Description
FIELD

The following invention disclosure is generally concerned with multi-media playback systems and specifically concerned with playback systems for vehicle event record playback and analysis.


BACKGROUND

Multi-media players are known. Multi-media players are designed to run on computer systems and play back electronic audio and video files of specific types. The multi-media players typically include user interfaces for users to control playback. For example, a user may control ‘Windows Media Player®’ to play video encoded media files consistent with a format defined in the MP4 standard.


In some multi-media players the user interface controls are customized based on a user's internet browsing habits, computer system characteristics, and network authentication information. In some multi-media players, a user may control the visual appearance of the information displayed to the user.


SUMMARY

One aspect of the disclosure relates to vehicle event record playback systems including devices and methods. It is a primary function of these systems to provide review and analysis means suited and arranged in view of information captured by vehicle event recorders, active safety systems, and/or other systems installed in and/or coupled to a vehicle. In contrast to the prior art, systems presented here do not suffer limitations which prevent their use for synchronized display of data captured by vehicle event recorders, active safety systems, and/or other systems.


Vehicle event recorders may produce event record datasets in response to anomalies and/or other events detected during vehicle operation. Active safety systems may alert a vehicle driver to potentially dangerous conditions detected in and/or around a vehicle during operation of the vehicle. Because event record datasets and/or information generated by the active safety system may contain considerable amounts of data in many data formats and arrangements, they may be difficult to parse, read, interpret, and/or use. In known systems, some vehicle event recorder and/or active safety system data was manually reviewed and certain data subsets of greatest importance were manually developed from raw data into visual presentations by way of standard software such as spreadsheet plotting utilities.


Vehicle event data playback systems described herein may include advanced playback of vehicle event recorder data, active safety system data, vehicle subsystem data and/or other data. The playback of the vehicle event recorder data, the active safety system data, the vehicle subsystem data, and/or other data may be in real time, and/or may be played back at a later time. The playback of the vehicle event recorder data may be played back via a user interface located in the vehicle, a remotely located user interface, a remotely located computing device, and/or via other systems. These systems may include visual devices arranged to express vehicle performance data in graphical, image and/or alphanumeric forms. These systems may be arranged to present data in logical arrangements whereby many different types of datasets collected at various vehicle sensors may be presented in time synchronized schemes along with a plurality of complementary data. Data presented in this fashion may permit greater analysis and may enable reviewers to devise coaching feedback, for example.


In a first example, vehicle performance data may be collected by way of a vehicle's onboard electronic control unit (ECU). The ECU may include an engine control module (ECM), for example. The data from the ECU may be included in, and/or associated with other data collected at the same (or nearly same) instant in time from other sources such as data from aftermarket sensors (e.g., an accelerometer) coupled with the vehicle, data from an active safety system installed in and/or coupled with the vehicle, and/or data from other sources that generate information relevant to vehicle operation. An event record may be prepared in a manner where at least some data measurements are associated with a timestamp or other time synchronization scheme. In this way, synchronized playback of data from a plurality of data sources may be enabled.


On playback, a human reviewer may be presented with simultaneous views and expressions of multiple data elements. The individual data elements may be presented in a visual nature on a common display field of a graphical user interface (GUI). Since these data elements often have a high level of interdependence, simultaneous expression of their instantaneous values in a time sequenced series playback enables may enhance vehicle event record review.


Graphical user interfaces of these systems may include control objects. The control objects may be responsive to data values of vehicle event record datasets. The control objects may be expressed visually. A control object may be a visual element in the graphical user interface that is associated with data and/or a data stream from one or more sensors. Control objects may include parametric input couplings, data interfaces, underlying logic code which defines performance, a visual expression, an event set, triggers, an instantaneous state, and/or other control objects. Combinations of various related control objects may operate together in synchronization to characterize and/or describe actions and/or states associated with a vehicle and its many subsystems during a recorded event.


The control objects may be arranged to visually express data collected from vehicle subsystems in graphical and/or alphanumeric forms. In some implementations, the control objects may visually express data associated with standard ECU systems, an active safety system, a vehicle event recorder, and/or other systems, and present that data in one or more visual forms in conjunction with simultaneous playback of related video, for example.


The control objects of the graphical user interface may be coupled to an event timeline whereby presentation of data by the control objects conforms to the event timing. An event timeline may have a start-time, an end-time, and/or a continuous period of time therebetween. An event record dataset may include an event timeline definition for events recorded at a vehicle event recorder. For example, the controls presented by the GUI may be connected to a single timeline and that timeline may be coupled to the event time.


In some implementations of these systems, ‘video playback’ may be an included feature. Accordingly, video players may generally be included as a primary element of these graphical user interfaces. Video player systems of these devices may include those suitable for playback of common video captured at a vehicle event recorder video camera. These video players may also be suitable for playback of virtual video. Virtual video may include image series playback where the images are from sources other than a vehicle event recorder. These may include forward and aft video camera views, street view image series, mapview image series, and even bird's eye view playback. Video playback may be synchronized with the ECU data, active safety system data, and/or vehicle event recorder data, for example.


Other control objects found in the playback apparatus may include graphical representations of acceleration data in one or more coupled controls. One feature may relate to a notation facility which may be coupled to an event timeline. The notation facility permits replay of manually prepared notes to which a time Association has been made and assigned in synchronization with event replay.


These and other objects, features, and characteristics of the system and/or method disclosed herein, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures.

DETAILED DESCRIPTION


FIG. 1A-1G illustrate various views 3 of a graphical user interface included in and/or associated with a vehicle event data playback apparatus. The graphical user interface and/or the vehicle event data playback apparatus described herein may be configured to visually present a user with information related to operation of a vehicle. In some implementations, the user may review the information related to operation of the vehicle in real time, responsive to the vehicle being involved in a vehicle event, responsive to an active safety system alert, and/or at other times. The vehicle event may include an active safety system alert (e.g., events on the vehicle bus that indicate activations of active safety system), an accident, a specific driving maneuver, vehicle speed exceeding a set threshold or the posted speed limit, a narrowly avoided accident where a driver braked hard and/or swerved, trigger activations from external systems, a driver pressing a button (an/or gesturing via some other interface) designed to indicate an event, and/or other events. Specific driving maneuvers and/or active safety system alerts may be related to swerving, a U-turn, freewheeling, over-revving, short following (e.g. tailgating), a pedestrian detection and/or collision warning, driving in reverse, vehicle rollover, antilock braking, a forward collision warning, a lane departure warning, other events and/or maneuvers.


In some implementations, an active safety system may be installed in the vehicle at manufacture. In some implementations, the active safety system may be an aftermarket system installed in and/or coupled with the vehicle. The active safety system may be configured to detect and/or alert a vehicle driver to dangerous and/or other driving conditions. An active safety system alert may cause the driver to take action to prevent and/or lessen the severity of collisions, for example, and/or other undesired events. The active safety system may include one or more sensors, one or more processors, a user interface, and/or other components. The one or more active safety system sensors may be configured to generate output signals conveying information related to vehicle safety and/or other information. The one or more processors may be configured to detect unsafe conditions during operation of the vehicle based on the output signals from the active safety system sensors, and/or other sources of information. The one or more processors may be configured to generate one or more alerts responsive to detection of unsafe conditions. The active safety system may be manufactured by one or more manufacturers including, for example, Meritor-Wabco, Bendix, Mobileye and/or other active safety system manufacturers.


The vehicle event data playback apparatus visually presents information that is generated based on output signals from one or more sensors associated with the vehicle. The vehicle event data playback apparatus may synchronize the presented information such that information from individual sensors may be compared and/or viewed at the same time by the user. The information from individual sensors may be compared and/or viewed at the same time by the user at one or more time points before, during, and/or after a vehicle event, an active safety system alert, and/or at other times.


The sensors may be configured to generate output signals conveying information related to the operation and/or the context of the vehicle. The sensors may be configured to generate output signals conveying information related to one or more operating parameters of the vehicle. Information related to the operation of the vehicle, the context of the vehicle, and/or operating parameters of the vehicle may include vehicle safety information, vehicle event information, vehicle environment information, vehicle subsystem information, and/or other information. Information related to the operation of the vehicle, the context of the vehicle, and/or operating parameters of the vehicle may include feedback information from one or more of the mechanical systems of the vehicle, and/or other information. In some implementations, at least one of the sensors may be an active safety system sensor. In some implementations, at least one of the sensors may be a vehicle system sensor associated with an ECU system of the vehicle. Information related to the context of the vehicle may include information related to the environment in and/or around vehicle. In some implementations, the output signals conveying the information related to the context of the vehicle may be generated via non-standard aftermarket sensors installed in the vehicle as part of a vehicle event recorder, for example. The non-standard aftermarket sensors may include, for example, a video camera, an accelerometer, a gyroscope, a geolocation sensor (e.g., a GPS device), a radar detector, an audio sensor (e.g., a microphone), and/or other sensors.


The vehicle event playback apparatus may include and/or communicate with the vehicle event recorder. The vehicle event recorder may be configured to record data associated with vehicle events. The vehicle events may be triggered to be recorded based on the information generated by the active safety system (e.g., the active safety system sensors and/or the active safety system processor(s)), the information from the non-standard aftermarket sensors installed in the vehicle, the information from the vehicle system sensors associated with an ECU system of the vehicle, pre-determined vehicle event profiles, and/or other information. In some implementations, the vehicle event recorder may be triggered to record the vehicle events based on a trigger, for example. A trigger may include and/or result from a comparison of the information conveyed by the output signals from the sensors to criteria included in the pre-determined vehicle event profiles. A trigger may be one or more logical criteria that is determined to have been met by the system. The vehicle event recorder may be configured to obtain one or more pre-determined vehicle event profiles. The one or more pre-determined vehicle event profiles may include criteria sets associated with the vehicle events. A specific vehicle event may be triggered to be recorded based on the information conveyed by the output signals and the obtained pre-determined vehicle event profiles by comparing the information conveyed by the output signals (and/or information determined based on the output signals) to the criteria sets such that a specific vehicle event is triggered to be recorded responsive to the information in and/or determined from the output signals satisfying one or more individual criteria in a criteria set associated with the specific vehicle event. A vehicle event recorded by the vehicle event recorder may include audio information, video information, information from the ECU, information from the active safety system, and/or other information.


By way of a non-limiting example, the system may detect that a driver has exited his lane 3 times in a 90 second period, where the criteria for triggering the event included activation of a lane departure warning system (e.g., information may be communicated across the ECU to the present system) and time elapsed. As another example, an event may be triggered to be stored based on criteria that include following distance as measured by an active safety system and time (e.g., following distance of less than 1.4 seconds for 10 or more seconds), where the distance is measured and based on a formula inclusive of time.


The vehicle event playback apparatus and/or the vehicle event recorder may include one or more processors. The processors may be configured to synchronize (e.g., systematically align) the information included in the output signals from the one or more sensors associated with the vehicle (e.g., the active safety system sensors, the vehicle system sensors associated with the ECU system of the vehicle, the non-standard aftermarket sensors installed in the vehicle as part of the vehicle event recorder). The processors may synchronize the information even though the information from the individual sensors may not be generated and/or received by the vehicle event playback apparatus at the same time. Synchronization may include associating data from two or more individual output signals with a single event timeline for a given event. An event timeline may have a start-time, an end-time, and/or a continuous period of time therebetween, for example.


In some implementations, the output signals from the one or more sensors may include time information indicating a time the information was generated, the order in which the information was generated, a timing of the generated information (e.g., periodic and/or continuous), and/or other time information. In some implementations, the processors may associate information in the individual output signals with a corresponding time location in the event timeline based on the time information included in the output signals.


In some implementations, associating information in the individual output signals to a corresponding time location in the event timeline based on the time information included in the output signals may not produce a synchronized event timeline. For example, the timing information in a first output signal (e.g., information indicating the start of an event at 2:40:48 PM) may not coincide with the timing information in a second output signal (e.g., information indicating the start of the same event may be received at 2:41:02 PM) even though both output signals include information related to the same event. In such implementations, the one or more processors may analyze information in the individual output signals and associate corresponding information in the individual output signals with the same time location in the event timeline, regardless of any time information in the output signals.


Analyzing the information in the individual output signals may include searching for expected information in individual output signals and associating the expected information with one or more appropriate time locations in the event timeline. Information conveyed by a first output signal may cause the processors to expect information in one or more other output signals. Continuing with the example above, one or more processors may determine that the information in the first output signal indicates the start of an event and may associate the information with the start of an event timeline (e.g., at 2:40 PM). After determining that the information in the first output signal indicates the start of the event, the one or more processors may search the information conveyed by the second output signal for information that also indicates the start of the event, regardless of any time information included in the output signal. After finding information in the second output signal that also indicates the start of the event, the processors may associate the found information with start of the event in the event timeline.


In some implementations, associating information in the individual output signals to a corresponding time location in the event timeline may be performed by the vehicle event playback apparatus. In some implementations, associating information in the individual output signals to a corresponding time location in the event timeline may be performed by the vehicle event recorder. The various data streams recorded within an event may involve some delays in the data collection process. These delays may vary by the signal (e.g., acceleration data may be received “faster” than the OBD vehicle speed data and even “faster” than the GPS data). These delays may be related to how the underlying sensors collect data. For example, accelerometers may be MEMS sensors that provide sub-millisecond readings. OBD vehicle speed measurement may be derived from an optical wheel speed sensor that generates pulses where the pulse periods are proportional to vehicle speed. This means that the slower the vehicle, the larger the delay in speed measurement because two consecutive pulses are necessary to estimate the vehicle speed. These delays may be measured in tens of milliseconds, but nonetheless represent delays that may result in misalignment of data when compared to accelerometer signals, for example. GPS relies of triangulation of satellite signals to determine the vehicle location. Many GPS systems determine the vehicle location once every second. Two consecutive vehicle locations measurements are necessary to derive the speed (e.g., distance between the points divided by the time interval between the measurements). Therefore, speed measurements from GPS systems are typically delayed by one second. Another reason for the delays in input signals may be related to the various buffers employed by electronic devices as they transmit information. Many communication devices send data in packets, which involved waiting for enough data to become available before sending the packet of information. These wait times further contribute to the input signal delays.


In some implementations, by being aware of these fixed time delays, the system may be constructed to purposefully delay individual signals except for the most delayed signal such that the individual signals become aligned with respect to time (e.g., synchronized) with the most delayed signal. After synchronizing the signals, the vehicle event recorder may store the aligned signals in volatile memory and/or other electronic storage.


Responsive to triggering of a vehicle event, the event data may be saved from a volatile memory to a non-volatile memory. The vehicle event recorder may compensate for the known delay in individual signals such that the saved event may be properly centered around the trigger point. For example, the largest signal delay may be 1.75 seconds. In this example, the individual signals (other than the one with the largest delay) may be purposefully delayed by additional delays (1.75 seconds minus the delay for the particular signal), such that aligned data is written to volatile memory with a 1.75 second delay. At the time that a vehicle event is detected (e.g., at the time a detection trigger signal is received), the vehicle event recorder may record a 30 second event with 15 seconds before the detection and 15 seconds after the detection. Upon receiving the trigger signal, the vehicle event recorder may immediately select the last 16.75 seconds (15 plus 1.75) of event data to be written from volatile to non-volatile memory, and then save the remaining 13.25 seconds of data (15 minus 1.75).


An indication that the vehicle event was detected (e.g., a trigger signal) may also be delayed. Triggers such as external voltage signals, where the trigger is generated on the rising edge, may not involve delays. However, more complex triggers may rely on delayed signals and a triggering algorithm itself may introduce additional delays. For example, a simple accelerometer triggering algorithm that involves measuring braking force may be configured to trigger once deceleration of 0.5 g is maintained over 1.0 seconds. This means that the triggering signal may be generated once the 1.0 seconds elapses with deceleration exceeding 0.5 g. However, the trigger point would ideally be identified in the middle of this interval, or at 0.5 elapsed seconds after the deceleration first exceeds 0.5 g. Therefore, the triggering signal from this triggering algorithm may be considered to be delayed by 0.5 seconds. A vehicle event recorder may compensate for triggering delays when saving event data from the volatile memory to the non-volatile memory. In the above example where all aligned signals written to volatile memory are delayed by 1.75 seconds, upon receiving a trigger signal that is known to be delayed by 0.5 seconds, the vehicle event recorder may compensate for this additional delay by immediately selecting the last 16.25 seconds (15 plus 1.75 minus 0.5) of event data to written from volatile to non-volatile memory, then proceeding to save the remaining 13.75 seconds of data (15 minus 1.75 plus 0.5).


By way of another non-limiting example, the one or more sensors may include an accelerometer (e.g., associated with the vehicle event recorder), a camera (e.g., associated with the vehicle event recorder), a sensor associated with the vehicle ECU, and/or other sensors. The accelerometer may generate output signals indicating that the vehicle has started breaking. The accelerometer information (e.g., the braking start time) may agree with video images that show the vehicle beginning to slow down. Information from the vehicle ECU may not indicate that the vehicle is breaking until a short time later, when the vehicle ECU information is received by the one or more processors of the vehicle event data playback apparatus. In this example, the one or more processors of the vehicle event data playback apparatus may synchronize the information from the accelerometer, the camera, and the vehicle ECU system so the information may be presented to the user in a synchronized manner. The user may better understand the event because of the synchronized information. The user may better understand the cause of the event, the outcome of the event, road and/or other environmental conditions during the event, and/or other information related to the event by viewing the synchronized information.


As shown in FIG. 1A, view 3 includes a first (e.g., forward looking) video playback view 4, a second (e.g., vehicle interior driver video) playback view 5, an event timeline 7, a graphical representation 9 of information related to the operation and/or the context of the vehicle, one or more visual representations 11 of information related to the operation and/or the context of the vehicle, visual representations 13 of vehicle ECU information, a notation field 15, and/or other information. In some implementations, view 3 (as shown in FIG. 1B-1G) may not include all of the components of view 3 shown in FIG. 1A. The number of video playback views shown in the figures is not intended to be limiting. The number of video playback views does not necessarily correspond to a number of cameras included in the system. For example, even though in some of the figures only two video playback views are shown, there may be 1, 2, 3, 4, 5, or more cameras included in the system. The two views may playback information from any two of the cameras, and/or other components of the system.


In some implementations, view 3 may include additional components now shown in FIG. 1A (e.g., an additional playback view 5 as shown in FIGS. 1E, 1F, and 1G). In some implementations, the components may be presented with a different visual format. In some implementations, view 3 includes one or more active safety system fields 19 (shown in FIG. 1B, 1C, 1D, and FIG. 2). The one or more active safety system fields may present information related to detections and/or alerts by the active safety system. In some implementations, the active safety system fields may present a textual, numeric, graphical, and/or other representative indication of what the active safety system communicates to the driver of the vehicle. For example, the active safety system may alert a driver via a red/yellow/green color coded display that is part of the active safety system. The red/yellow/green color coded display may be reproduced in the one or more active safety system fields 19 of the graphical user interface of the vehicle event data playback apparatus. In some implementations, the active safety system fields in view 3 may reproduce the active safety system detections and/or alerts presented to the driver in real time and/or at another time.


The additional components of view 3 are described in more detail below. The information presented by the one or more active safety system fields and/or the other components of view 3 of the graphical user interface may be synchronized by the vehicle event recorder and/or the vehicle event data playback apparatus and displayed to the user at the same time. The synchronized display may be in real time (e.g., a remote user may view the synchronized information while the driver is operating the vehicle) and/or at a later time.


The graphical user interface may be specifically designed to function and/or cooperate with the vehicle event recorder, the active safety system, and/or the event dataset/alert information they produce. Such a graphical user interface may be interactive and/or responsive to user/operator inputs affected by a computer and/or other peripheral devices. For example, a ‘point-and-click’ action of a computer mouse, entering and/or selecting information via a touch screen, and/or other user/operator inputs. In some implementations the graphical user interface may be presented to a driver of the vehicle and/or other users (e.g. located at the vehicle and/or located remotely) via a user interface associated with the active safety system. In some implementations, the graphical user interface may be presented to a driver of the vehicle and/or other users via a user interface separate from the active safety system. In some implementations, the alerts and/or other information generated by the active safety system may be presented to a driver of the vehicle and/or other users via the graphical user interface of the vehicle event record playback system.


This system may include couplings to a vehicle event recorder and/or data captured via the vehicle event recorder, couplings to the active safety system and/or data captured via the active safety system, and/or other systems. This system may include one or more processors, one or more display devices, one or more graphical user interfaces, and/or other components. This system may receive as input vehicle event recorder datasets, information generated by the active safety system, and/or other information. Prescribed program code may be executed by the one or more processors to operate on datasets received from the vehicle event recorder, the active safety system, and/or other sources. Data from these datasets may be passed into control objects as parametric input to drive the various visual states of the control objects.


The graphical user interface of the vehicle event recorder dataset playback system presented herein may be comprised of a plurality of control objects. These control objects may include visual depictions of information which may change in response to user interaction and/or specific data values of a dataset under review. Some of these control objects may be interactive and adjusted responsive to ‘point-and-click’, ‘click and drag’, touch screen touches, and/or other user interactions. Control objects of these systems may be coupled to, and/or designed to cooperate with, data types and/or data objects unique to vehicle event recorder event record datasets, information from the active safety system, and/or information from other sources.


The control objects may have an appearance and/or data ranges that are correlated with information generated by vehicle event recorders during operation of vehicles. The control objects of these graphical user interfaces may have be configured to visually express data and/or information which is contained in a vehicle event record event dataset, information generated by the active safety system, and/or other information. Illustrative examples are included herefollowing.


Control objects may include and/or display information based on logic code. Logic code (not visible to a user) may facilitate receipt of input data, parsing that data, processing the data in accordance with prescribed algorithms (e.g., which are part of the logic code), providing outputs which may include adjustments to the visual states of the control objects, and/or other actions.


It should be noted that the series of control objects described below and shown in FIG. 1-FIG. 11 are not intended to be limiting. The system described herein may be configured to generate control objects related to any vehicle operation information that would be helpful for a user reviewing event data recorded before, during, and/or after a vehicle event.


A vehicle event recorder may be configured to capture compound datasets relating to vehicle operation and/or events during a finite period. Accordingly, one or more aspects of this vehicle event playback system may relate to a timeline control object and/or its relationship with the event dataset, and/or other controls of the graphical user interface. Timeline control objects may include an associated time range equivalent to the time range of the event period. The time range associated with a given event may vary in length from a fraction of a second to several tens of minutes or even hours. However, many events recorded by vehicle event recorders may be a few seconds or a few tens of seconds. Timeline control objects in accordance with these teachings may have one or more of a ‘start time’, an ‘end time’, a continuous time period therebetween, and/or other features. The ‘continuous’ time period between the start time and the end time may include a finite number of frame instants and/or frame stops, for example. These may be discrete moments in the event period for which an image may be captured. A timeline control object of these graphical user interfaces may be synchronized with the time span of events recorded by a vehicle event recorder when its start time and end time are set in accordance with specific related values in an event record dataset. In the example illustrated as FIG. 1, an event record includes a start time of 4:19:35 and an end time of 4:20:02 for a total event period of 27 seconds.


In some implementations, via the graphical user interface, a user may control the length of the event period, select (e.g., by clicking and/or touching a location) an individual time within the event period, continuously play the frame instants, rewind and/or fast forward the frame instants, and/or control the length of the even period in other ways.


For improved ease of operation of these timeline controls, when playing back vehicle event record data, it may be useful for a user to arrange the control to extend an appreciable length of interface regardless of the event period extent. That is, a timeline control which supports a twenty-seven second event may be the same size as a timeline control which supports a 10 minute event. Thus a timeline control may be ‘normalized’ to the event period without change of its physical size. In view of the data contained in an event record dataset, the start time and/or the end time may be associated with the timeline control extremities, and/or 100% of the timeline control length may be divided evenly and/or occupied by the entire event without dependence upon the actual extent of the event period. Accordingly, the timeline control object may cooperate with playback of the vehicle event recorder output in that the timeline may auto-adjust to normalize for events of any period length.


A timeline control object may be adapted to match the extent of a time period of a specific event under replay and/or thereafter may be set to agree with a specific event record. For example, as shown in FIG. 2, timeline pip markers 23, which may indicate noteworthy features of the event record, may be distributed about the timeline to provide access to information relating to those features. Timeline pip markers 23 may be pre-encoded elements made responsive to mouse clicks, touch screen touches, and/or other control indications entered and/or selected by a user via the graphical user interface and/or one or more peripheral devices. These pip markers may be associated with an instant in time and/or a time period which is a subset of the entire event period. Other control objects of the graphical user interface may be coupled to these pip marker objects and/or may be responsive thereto. They may be responsive to mouse clicks, touch-screen touches, and/or other control gestures associated with the pip markers. FIG. 2 also illustrates event timeline 22, image series players 21, 24, and a vehicle location 25.


The timeline object may include a timeline replay instant indicator control object. The instantaneous state of a timeline replay instant indicator may specify a replay instant in time, the replay instant to which other controls may be bound and responsive. A timeline replay instant indicator may mark the present instant of the playback system at a given time. The present instant may represent a moment in the event period between the event start time and the event end time. For controls bound to the timeline control object, the present instant time may be used to set the visual state of the control (individually, or as a coordinated group). The visual state of a control object may be different for the individual instants of the event period. When the timeline replay instant indicator is associated with another time instant of the event period, either manually or during a pre-play execution, individual ones of the controls bound to the timeline control may automatically update their visual state to represent data captured at that moment of the event period. Timeline replay instant indicators may be responsive to click-and-drag, touch, and/or other actions, and/or may be responsive to automated replay controls such as ‘play’ control, ‘fast forward’ control, ‘rewind’ control, etc.


Replay controls of these systems may include, for example, a ‘play’ control button, ‘fast forward’, rewind, ‘loop’, and/or other controls. Timeline control objects of these vehicle event playback systems may also include such controls.


Timeline control may be sensitive to keyboard input. For example, left and right arrow keys may be used to advance the timeline backward or forward, respectively, by one video frame (e.g. 0.25 seconds for 4 frames per second video) at a time. The space key may be used to start and/or pause the event data playback. Page Up and Page Down keys may be used to advance the timeline in larger fixed time intervals, such as 5.0 seconds forward or backward, respectively.


Modes of vehicle event playback systems presented here may include side-by-side playback of a plurality of videos (time series presentation of images). In two separate video control objects, a prescribed video may be played back synchronously. For example, a view from the front of a vehicle and a view from the back of the vehicle may be synchronized to represent separate images taken at the same point in time and played side by side. In some implementations, the synchronized video may be synchronized with vehicle ECU data, for example. This may be useful in gaining an understanding of a complex scene which may have more than one point of view, such as a driving incident. For example, in a driving incident it may be important to consider the precise timing of event in the view of the driver and/or in view of traffic ahead. When these two views are considered together, an expert reviewer may draw more precise conclusions with regard to the event details. Accordingly, the event playback systems may include side-by-side video playback controls for playing back videos of two or more unique viewpoints.


Vehicle event recorder systems may include a plurality of video cameras positioned at a plurality of video capture stations (locations). An individual video capture station may have a unique viewpoint relative to other video capture stations. In some vehicle event recorders, a ‘forward-looking’ camera may be arranged to capture a traffic view ahead of the vehicle and a second reward looking camera may be arranged to capture a view of a passenger/driver space.


There may be a time relationship between these two video views because actions taken by a vehicle operator may relate to the traffic and conditions ahead. One may understand a driver's response to things which may be discovered observable in the forward view. The vehicle event data playback systems may include a plurality of video players where individual views of the video players may be synchronized in time to the others and/or timeline control objects, and/or with respect to the timeline replay instant indicator. Where vehicle event recorders support more than two video cameras, a single timeline control may be used to synchronize those in a similar manner.


An operator/reviewer of these vehicle event data playback systems may ‘scroll’ through discrete video frames of the event timeline by adjusting the playback instant indicator, for example via ‘click-and-drag’, touch, keyboard key strokes, and/or other types of actions. Accordingly, the graphical user interface of this invention may include video playback controls coupled to the playback instant element of a timeline control object. In this way, two separate views about the vehicle environment may be considered simultaneously in a side-by-side arrangement where both views represent substantially the same instant in time as synchronized by the timeline control.


While some versions of these systems include side-by-side playback of forward facing and rear facing (for example) views taken from video cameras in a vehicle event recorder, (e.g., ‘real’ video), alternative versions may include at least one video playback display in which a ‘virtual video’ is presented. A virtual video may include a time series of images whereby the images are captured in a system which is not a vehicle event recorder. However, these virtual videos may relate directly to the events captured. For example, one type of virtual video in accordance with this teaching may present images having dependence upon the event timeline. Another example may have dependence upon the vehicle position as a function of time. Still another may have a position dependence with prescribed offset. Other examples are contemplated. More details of these types of virtual videos follow.


In some implementations, as shown in FIG. 3, an image series player 31 (video player) may be arranged to play an image series which was not recorded by the vehicle event recorder. Rather, a plurality of still images is recalled from a prepared database to form an image set which may be played in series. Those images when played together as a ‘video’ in the video player may constitute a ‘virtual video’ for purposes of this teaching. However, this replay may be well coordinated and having direct dependence with respect to the event record. For example, this virtual video timeline may be synchronized with the event timeline 32. The actual location of a vehicle as recorded by the vehicle event recorder may be coupled to the viewpoint from which the recalled images are made.


When the timeline control is set into a ‘play’ mode, the video of actual captured images may appear in a video player control adjacent to a second player which plays the virtual streetview video. This virtual video may include images from the same locations and/or viewpoints with respect to the event period, but these images may include enhancements and augmentations to bring a more complete understanding of the actual event. In one example, streetview images provided by a service like Google's StreetView system may be recalled in view of a plurality of position measurements taken by the vehicle event recorder. For this plurality of locations (vehicle's location as measured by a GPS for example) captured over the period of a given event, a streetview image from a corresponding location may be recalled from the image database. Individual recalled images may then be assigned a time instant corresponding to those times from which the playback timeline is comprised to assemble a virtual video of streetview images which directly corresponds to the video actually captured at the vehicle event recorder cameras. One advantage may lie at least partly in the clarity of the recalled images which may have been provided on a nice sunny day in comparison to images captured by the vehicle event recorder which may be of inferior clarity due, for example, to inclement weather including fog or sun glare, nighttime darkness, a large vehicle that obstructs the view of the event recorder, and/or other factors. Further advantages may be realized in view of the labels which may be may be incorporated with the prepared streetview images. For example, address label 28 may indicate a street address most closely associated with the image viewpoint. FIG. 3 also illustrates event timeline 32, image series player 34, vehicle location 35, a street address 38 corresponding to the vehicle location, a street view image 37 corresponding to the vehicle location, and/or other information.


Another benefit of this approach is that streetview may be further manipulated by the user to gain a better understanding of the environment in which the event was captured. For example, the user may pause the event playback, then rotate the streetview to show the image to the left, right or behind the vehicle. The system may be configured such that this user action would temporarily decouple the streetview from the event playback. Upon restarting the playback of the paused event playback, the system may be configured such that streetview would then realign and show the view in front of the vehicle again.


It may be inconvenient to view many videos simultaneously. To address this, these players may have two players side-by-side with the video type selectable in the interface by way of a tab strip control 33, which as shown in FIG. 3 for example, may include five tab selections (e.g., “BackCam”, “StreetView”, “MapView”, “BirdseyeView”, “Driver View”, and/or other tab selections). In agreement with which tab is selected and triggered, the video playback may be switched between the possible video presentation types. The player may present a synchronized playback of both real and virtual videos in agreement with the event period and/or the timeline control. The example of two side by side players is not intended to be limiting. The system described herein may have any number of players in the graphical user interface. The multiple players need not be side by side. They may be positioned anywhere in the graphical user interface that is helpful to the user. Additional views that correspond to additional cameras may be provided, for example. In some implementations, the cameras may include a forward road camera, an interior cab camera, a left side backward facing camera, a rear of the vehicle backward facing camera, and/or other cameras. The additional views/cameras may give greater perspective for a review analyst and/or a coach reviewing the information.


There may be another type of virtual video which may be supported by these playback systems which relates to moving maps. A map view virtual video is depicted in FIG. 4. In a fashion similar to that described in the streetview embodiment, a plurality of map images may be prepared and saved to form an image series consistent with an event record dataset. The vehicle location and/or the event timeline 41 may be considered in forming a series of map images suitable for playback in a mapview video player 42.


A separate map image 43 with appropriate scale, size and orientation may be presented in the viewer for every discrete instant of the event period as represented in the event timeline. When playback instant control 44 is moved to another time (constant) of the event timeline, the vehicle also moves (in most events). The new vehicle location 45 may cause a new map and/or a separate map image to be allocated and displayed for that time instant. The image in image series player 47 may correspond to vehicle location 45. The vehicle's position within the map may be indicated by an icon marker 46 to reflect the position of the vehicle as measured by the vehicle event recorder. In a an event replay, the series of map images may be played back synchronously alongside the actual forward view images (for example) captured at the vehicle event recorder camera.


A mapview player in accordance with this teaching may be useful when it is arranged to present maps with enhancements and/or markings which may be derived from information in the event record dataset. For example, when actual vehicle speeds are compared to local speed limits, a determination may be possible with regard to regions in which a speed infraction occurs. A graphical representation of the same may be included superimposed with the maps presented.


With reference to FIG. 5, timeline control object 51 agrees with the event record dataset from a vehicle event recorder. A playback instant control 52 marks an instantaneous moment of the event period. At the moment 4:19:38.50 p.m. indicated in a numeric label control 53, the vehicle GPS system determined the vehicle location at latitude 32.8295 and longitude −117.2733 as recorded by the vehicle event recorder's position determining system and position is reported numerically at position label control 55. In some implementations, the latitude and longitude information may be translated into a street address by the system and/or presented to the user in a field of the graphical user interface.


With the video player set into a map view mode 54 by a tab strip tool 56, a map image 57 suitable in scale and location may be presented that shows the vehicle's location at the corresponding instant in time. An icon image of a car 58 (for example) may mark the location in the map. In addition, a spatial highlight 59 for example (highlighting portions of Bonair and Draper streets in the image), may be superimposed on the map image to mark regions where speeding infractions have been identified.


Timeline marker 60 may designate a finite period of time within the event period when the speeding occurs. Thus, some timeline controls of these systems may include marker objects aligned and/or cooperative with elements appearing in virtual videos. This cooperation may be due to associations with time instants within the event period.


Both the streetview player and the mapview player may offer advantages in reaching a complete understanding of a scene. They may be augmented based on information collected by a vehicle event recorder.


Another virtual video player that may be included in these systems may be characterized as a bird's eye view virtual video player. Illustrated in FIG. 6, a bird's eye view video player of these systems may include images taken from an elevated viewpoint, for example images made from an airplane and/or satellite. In consideration of the vehicle's time-dependent position as measured and/or recorded by a vehicle event recorder, images may be selected from a prerecorded database of so described images, and/or obtained from other sources.


Timeline control 61 specifies an instant in time by a playback instant control 62. Video player display 63 may include an image 64 and a ‘car’ icon marker 65 to indicate the location of the vehicle at the capture time 4:19:38.50. When tab strip 66 is used to set the video player into a bird's eye view mode 67, an image series of perspective images made from altitude may be played back in time with respect to the event timeline. As the event player executes playback of event data, images displayed by image series player 68, bird's eye images 64, marker icon 65, and/or other components of the system, may be updated for instants of the timeline to reflect appropriate views of the event scene.


Because the image viewpoint may be selectable, it may be possible to specify that the viewpoint be constant at a virtual location, for example 100 meters behind the car and/or 50 meters above the car, and the view direction may point in the direction of travel with respect to the vehicle. In this way, the bird's eye view playback virtual video may be envisioned as if a helicopter video camera followed the car throughout the event to make the video images. A reviewer may gain a clearer understanding of the event environment as presented in a synchronized manner alongside with other event record information.


Accordingly, these vehicle event data playback systems may include one or more of a real view video player, a virtual video player, and/or other video players which may be arranged to interact with event data recorded in vehicle event recorders. Individual ones of these specialized video players may provide a time synchronized image series in conjunction with a visual presentation of other related event record data.


While the preceding description sets forth several video playback control objects, the following description is directed to other aspects of these vehicle event playback systems which may not be based upon data from image systems. Rather, the graphical user interface may control objects presented herefollowing to express non-image data from a plurality of sources. In some implementations, these sources may include onboard data systems. In some implementations, information sources may include those which are external with respect to a vehicle and/or its vehicle event recorders.


Control objects of graphical user interfaces of these playback systems bound to vehicle onboard systems may have two primary but non-limiting types including: 1) control objects bound to data from sensors deployed as part of a vehicle event recorder apparatus, for example, a vehicle event recorder may include accelerometers which measure G-force levels in two orthogonal spatial dimensions while a vehicle is being used; and 2) a control object bound to vehicle subsystems characterized as those installed by a vehicle manufacturer. Other types are contemplated. Data provided by way of a vehicle's ECU systems may be received, managed, parsed, and/or time-stamped at a vehicle event recorder which forms a dataset to which control objects of the graphical user interfaces may be bound. In some implementations, control objects of graphical user interfaces of these playback systems bound to vehicle onboard systems may include a third type. The third type of control object may be associated with the data generated by analysis modules of the vehicle even recorder, such as a wasted fuel estimate, triggers for dangerous driving maneuvers, calculated fuel consumption from mass air flow sensors, and/or other data generated by analysis module of the vehicle event recorder.


Some control objects of these systems may be bound to data sources not part of a vehicle event recorder system and/or external with regard to vehicle subsystems. These control objects may be nevertheless implicitly strongly coupled to event record datasets which are subject to playback in these devices and methods. In one illustrative example, a notation system which associates an expert reviewer's comments and notes with portions of an event record in a note field or notation control object may be coupled to receive data therefrom. Details of these types follow.


In one version, a control object and/or plurality of control objects may be coupled to the timeline control and thus the event period to affect time synchronization between these. Acceleration control objects may be arranged to visually show acceleration data collected during an event captured with a vehicle event recorder. With respect to acceleration data collected in a vehicle event recorder, it may be useful to present this type of information in two fashions. First, it may be useful to present instantaneous acceleration data associated with an instant of time during the event period. In a second fashion, acceleration data collected over the entire event period (or finite subset thereof) may be displayed in a graph of two axes. Force data may be presented in a form where the abscissa of which may be time, and the ordinate force.


For example, in FIG. 7, a view 72 of a first acceleration control object includes a line graph 71 representation of acceleration data into orthogonal directions. ‘G-force’ or acceleration is plotted versus time to form line representations 73 of acceleration data. A playback instant indicator 74 is synchronized with the playback instant indicator 75 of the timeline control object both spatially and with respect to displayed data.


Another related acceleration control object 76 which expresses acceleration data in an alternative visual form is additionally illustrated. This 2-D expression of instantaneous force includes a pointer 77 which gives a visual representation of force in both forward/aft and left/right directions 78 (also synchronized with playback instant indicators 74 and 75). The acceleration control objects may be bound to information in the event record dataset whereby synchronization is realized with respect to the timeline control and other control objects similarly bound including the video display control objects. Accordingly, control objects may be arranged to present instantaneous data as well as plots of data over time. In both cases, these controls may be bound and/or responsive to the playback timeline 79.


Vehicle event recorder systems may produce information-rich event record datasets. Event record datasets of vehicle event recorders may include data captured at vehicle subsystems, for example, by way of the onboard diagnostics and/or ECU systems. In vehicle event recorder systems so equipped, data captured at various vehicle subsystems may be time-stamped in a scheme coordinated with the event period and/or with video frame capture rates. Where such data is time-stamped, it may enhance synchronous replay via these vehicle event data playback systems.


Accordingly, these vehicle event data playback systems may be suited for playback of vehicle event records having been formed with time-stamped data from factory installed vehicle subsystems. Some vehicle event recorder systems may be arranged to capture engine speed data and/or to associate a time instant with speed data measurements. Engine speed in ‘revolutions per minute’ or RPM, may be read from an ECU via a coupling to which a vehicle event recorder may be connected. In some alternative versions, engine speed measurements may be made via ‘aftermarket’ installed sensors and/or vehicle subsystem detector which may obviate need to directly couple with the ECU. In either case, when event record datasets which are compatible with these playback systems are prepared and recorded, individual engine speed measurements may be associated with an instant in time and/or “time-stamped”. In systems common in the art where engine speed is recorded, engine speed is generally recorded without regard for simultaneous and/or synchronized playback. In those systems, engine speed data may not be provided with an association with time. Because it is a goal of these playback systems to playback data in a synchronized fashion, it may be necessary to time stamp data in this way. Where vehicle subsystems, for example an engine tachometer, do not provide measurement data at a rate equal or similar to video camera frame rates, data smoothing and or data averaging may be used to improve a dataset or portion thereof to make it better cooperate with the objectives of these playback systems, which may include a discrete number of time instances on an event timeline. Common vehicle tachometers may not face this restriction and may be otherwise free to take measurements at a convenient rate including those rates having unequal periods between data measurements. To facilitate time synchronization in these playback systems, the moment any measurement is made may be accounted for.


Many modern vehicle manufacturers may include advanced electronic systems with many of the vehicle's subsystems. For example, a mechanical accelerator pedal often includes a transducer from which pedal position may be readily measured. However, electronic data which may exist within a vehicle's proprietary electronic control schemes may not always readily available for third-party use. In some implementations, vehicle event recorders may be unable to record information relating to vehicle performance parameters such as the odometer on light duty vehicles, the fuel flow meter on light duty vehicles, and/or other parameters. This is not intended to be limiting. The system described herein should be understood to utilize any information made available by the vehicle's subsystems. If unavailable types of information are eventually made available by the vehicle manufactures, it should be considered within the scope of this disclosure to include a control object associated with the newly available information.


In implementations where a vehicle event recorder may be successfully coupled to vehicle electronic subsystems to receive the difficult to obtain and/or newly released data, the vehicle event recorder may be adapted to pass the data and/or manage a timestamp scheme in conjunction with the vehicle event recorder. For example, if a vehicle event recorder operates with a video frame rate of 30 frames per second, but the factory installed odometer and/or fuel flow data only update three times per second, a data recording scheme may be set to rectify timing issues between these independent data sources so that an event dataset may accurately reflect an ‘instantaneous’ time value for the data elements.


Vehicle event recorder systems which record time-stamped engine speed data are not known in the art. As such, synchronized playback of same has been impossible. As shown in FIG. 8, in systems disclosed herein, engine speed information may be expressed graphically in a visual presentation, in an alphanumeric expression, and/or in other forms as at least part of an engine speed control object 81. An engine speed control object of this example may be comprised of graphical portions and/or alphanumeric portions. An analog arc 82 may provide a range continuum upon which instantaneous magnitude may be displayed by a pointer 83. A digital numeric readout 84 may allow an instantaneous report of engine speed for an instant of the event timeline 85. Playback instant indicator 86 may be moved (e.g. via mouse type computer pointing peripheral device) to any point along the timeline. The engine speed control object, which is bound to the timeline, may be updated to indicate the engine speed recorded at that particular time. In a similar control object, vehicle speed control object 87, pointer 88 may yield an instantaneous value of ‘31 mph’ on an analog scale, while a digital numeric value 89 may also be provided at vehicle speed label.


Event records which may compatible with, and/or may be played by these vehicle event playback systems may include measurement data from the groups characterized as those including: throttle position data, engine load data, power takeoff system data, malfunction indicator light system data, brake system data, antilock brake system data, automatic traction control system data, electronic stability control system data, excess fuel consumption system data, and/or other data. FIG. 9 illustrates an event timeline 91 having playback instant indicator 92 set at time corresponding to 4:19:53.00 p.m. that is coupled to a plurality of control objects. Individual ones of the control objects may be arranged to express time-stamped data in a visual presentation which may include both graphical and/or alphanumeric representations.


Most vehicle event recorder systems are incapable of recording data related to throttle position. However, this may remain a factor in accident analysis. For example, it may be useful to understand how much time passes between the time a red light traffic signal appears (detectable via forward view video review—for example) and the time a vehicle operator disengages application of power (e.g. removes foot from an accelerator pedal). Because it may be difficult to arrange a custom sensor to detect accelerator position, many vehicle event recorders may include datasets devoid of this critical data.


While access to this information may be available on a vehicle's ECU system, to date, it has been prohibitively difficult to couple vehicle event recorders to the ECU of modern vehicles. Where that has been achieved, the dataset produced by such advanced vehicle event recorders may include time synchronization management schemes with respect to its video camera. These systems may include time-stamped data regarding throttle state where an event record dataset having such timestamp throttle state data are available. These vehicle event data playback systems may be cooperative and/or provide graphical user interface controls which are suitably responsive to such event record datasets.


A graphical user interface with a throttle state control object may provide graphical expressions of throttle states, and/or other information. The control object may be coupled to an event timeline and/or corresponding event timeline control whereby the instantaneous throttle state for a time in the event period may be selectively displayed by the control.


In some implementations, an instantaneous numeric value 93 (digital) and/or a graphical expression 94 (analog) of the throttle state may be given for individual instants of the timeline control. When the playback instant indicator is moved to another position of the event timeline, the throttle state control may be updated such that data represented there is updated in synchronization with other controls of the graphical user interface, including video.


The video of the video playback control object may indicate a red traffic signal has occurred at 4:19:44. A user/reviewer may be able to see by sliding the playback instant control to that moment of the timeline that the throttle state remained at 100% (recall FIG. 1). However, when the playback instant control is advanced further down the timeline to about 4:19:46, the throttle position may be at 0%, for example.


This may be verified by considering vehicle speed 710 (shown in FIG. 7) data presented in a continuum chart. In it, a user/reviewer may see that the vehicle begins to decelerate just before 4:19:45. While the acceleration data may be a good indicator of when the driver releases the throttle, it will remain imprecise because of mechanical delays inherent vehicle powertrain systems and the overall vehicle dynamics. Also, using acceleration data alone will result in misdetection of vehicle deceleration that may be due to vehicle travelling uphill and the force of gravity acting against the forward momentum of the vehicle. That is, the accelerator pedal may stay depressed at 25%, which may maintain vehicle speed while travelling 55 mph on a level road, but will result in vehicle deceleration should the road grade change to 5% uphill. To learn the precise time the throttle was released, the playback instant control may be manipulated to indicate a time prior to 4:19:45 and the throttle state control may be reviewed. This control may more accurately tell a fuller story as it relates to the question “when did the driver respond” rather than the question “when did the vehicle respond”. Accordingly, in some circumstances a throttle state control well synchronized with related data and/or bound to a timeline control unit may tell the full story which otherwise could not be known in the absence of throttle state information.


Similarly, a graphical user interface engine load control object 95 may be included in some versions of these vehicle event data playback systems. Engine load data may help a user reviewing an event via the graphical user interface to understand how heavily loaded the engine is at its given speed (RPM). This may inform the user if the vehicle was heavily loaded with cargo, whether the driver had excess power that he could have used for an evasive maneuver, etc. A sensor installed by a vehicle manufacturer may produce data to indicate engine load on a scale from 0% to 100%. Data from the sensor may be available via the ECU, for example. Data which indicates engine load may be periodically detected and/or captured, then added to the event record dataset produced by the vehicle event recorders. This step may be done with attention to time calibration and/or time synchronization. For example, data from the ECU may arrive at irregular intervals. Or the data may arrive with extreme time jitter between successive measurements. This data may be used in playback systems taught herein after being synchronized with other events encoded in event records. It may not be enough, with respect to the present vehicle event data playback systems, to merely collect multiple readings of engine load. Because of the particular playback characteristics suggested here, engine load data (among other data) may be time stamped before being included as part of these event records.


Another information source which may relate to vehicle performance and/or which may be replayed in these event data playback systems may relate to power distribution. It may be useful to know when engine power is needed by, and/or being delivered to, auxiliary systems. If a vehicle engine is delivering power to coupled power consuming subsystems (e.g. refrigeration, hydraulic actuator, et cetera) an event record may be configured to indicate the status of power takeoff systems.


In some implementations, a power takeoff indicator 96 may be embodied as a binary indicator. A power takeoff control object arranged to indicate binary states for every instant of an event timeline may include a graphical portion, an alpha numeric portion, and/or other portions, for example.


As shown in FIG. 9, other control objects may be provided to visually present data collected from vehicle subsystems. For example, these may include a brake indicator control object 98, an antilock braking system ABS control object 99, an automatic traction control (ATC) control object 910, an electronic stability control ESC control object 911, and/or other control objects. The graphical user interface control objects may be driven by data contained in a vehicle event recorder event dataset, and/or be responsive thereto. These controls may be bound to the timeline control object whereby visual presentation of data in the controls may be time synchronized. These controls may present data in graphical, alphanumeric, and/or other presentations.


In systems which produce data having a limited few states, it may be convenient to present the data states via prescribed and/or preconfigured icon symbols. For example a malfunction indicator light (MIL) system may operate to provide driver alerts with respect to five types of malfunction in addition to a binary ‘ON’-‘OFF’ value 912. A low tire pressure icon 913 may be displayed to indicate a malfunction. The control object, which may remain synchronized with event playback, may be showing its ‘ON’-‘OFF’ indication and/or malfunction type via the displayed icon, for example.


In some implementations, vehicle event recorders may include an excess fuel consumption indicator. When a driver takes an action which may be determined to be one associated with excess fuel consumption, an excess fuel consumption indicator may provide a driver with instant feedback to signal the condition. Where vehicles are equipped with such devices, they may also provide data to be included in a vehicle event recorder event record dataset. Accordingly, these vehicle event data playback apparatus may include an instant driver feedback control object 914. Because feedback may be provided as a three color scheme (for example) in vehicles in which they are deployed, the instant driver feedback control object may similarly express these feedback states. This control object may be an example which illustrates the value of a visual playback of vehicle event records. When an indicator is given to a driver to alert him that a maneuver has caused excess fuel consumption, it may be useful to understand in detail a driver's response in order to administer appropriate coaching. The system described herein may facilitate visualization and/or understanding of details associated with vehicle operation. For example, a reviewer/coach may decipher a driver response to instant feedback relating to fuel consumption maneuvers.


The description of data collected via vehicle event recorder systems is not intended to be limiting. There may be information sources that are not part of the vehicle event recorder which contribute data that may be played back the systems described herein.


In some implementations, vehicle event recorders may record data from vehicle systems, from event records, and/or from other sources, which details many aspects of vehicle and/or driver performance. In some of these systems, a human reviewer may study video captured in an event record and/or prepare notes in accordance with observations made. Some of these notes may be general to the entire event period (e.g. a ‘no seat belt’ infraction) and/or others may be particular to specific time portions of the event period and/or a single instant in the event period. Once prepared, the notations may become appended to, and/or part of an event record. When event records are played back in these data players, these notations may be displayed via the graphical user interface.



FIG. 10 shows one illustrated example of a timeline control 101 coupled to a notation field control 102. The notation field may include numeric review data such as a score value 103 and icon indicator 104 related to severity, a review date label 105 and a note list 106 containing therein a plurality of note entries (two notes entries are shown in the example).


A first note 107 relating to an occurrence of “aggressive accelerating” may be coupled to timeline marker pip 108 while “other task” notation 109 may be coupled to timeline marker pip 1010. Finally, note field 1011 may contain text which describes the reviewer's observations as those relate to the ‘other task’ note. Since these notes relate to specific parts of the event period, event playback may be improved when note text is appropriately displayed with respect to the note time association during the event data playback.


Access to several of these notes may also be affected by pointing and clicking, touching, etc., on the timeline pip marker elements. For example, if a user were to click on/touch the diamond shaped marker pip, the “other task” note closes and the “aggressive accelerating” note opens to reveal text of that note. In this way, access to appended notes may be readily available via timeline cues.


The notation control object described in the foregoing graphs may be illustrative of a first kind of information whose source may not be from onboard a vehicle but may be related to a vehicle event playback. There may be other sources which provide information related to a vehicle event but are not part of the vehicle, any of the vehicle's subsystems, or a vehicle event recorder.


Another information source external from the vehicle may include one which reports on environmental conditions related to the time and location of the recorded event. In one type of environment control object 1012, the state of the weather may be reported as recorded in remote weather reporting stations. For example, if an event recorder produces an event record with location and time information, a weather station may report ambient temperature via text label 1013. It may report whether or not the roadways were dry or wet at that time via icon display 1014. It may indicate whether or not the roads were icy or snowy. These systems may indicate whether or not the event occurred during a windy day. In view of sidereal time, and in view of a vehicle's direction of travel (as recorded by a vehicle event recorder), this control object may indicate the level of sun glare 1015 which may have hindered a driver's visibility during an event. A weather reporting station accessed via the internet (for example) before, during, or after an event record is made, may provide such data.


Other information sources external from the vehicle that may be helpful to a user reviewing an event via the graphical user interface may include databases containing speed limit information and/or road type information (e.g., freeway, major boulevard, two-lane road), sources of information about a traffic level, and/or other information.



FIG. 11 illustrates additional features. For reference, event timeline control 111 is illustrated in this drawing.
