The present disclosure relates generally to a device and system for determining the status of a vehicle, such as, for example, speed, location, accident, and the like, and transmitting associated data. More particularly, the present disclosure relates to a portable device for measuring data associated with vehicle movement and position, determining an unsafe driving status possibly associated with speeding, unstable driving conditions, an accident or other notable event, and transmitting data and/or alerts based on the determined status and/or measured data.
Conventional vehicle status or accident detectors are often used to promote safer driving and to allow emergency response professionals to respond faster to accidents. These conventional detectors are often built into vehicles, therefore making it difficult to continuously measure vehicle status of users who may have multiple vehicles. Additionally, the existing conventional detectors often measure only a single parameter (e.g., speed), and are unable to measure multiple parameters at once to allow for an early detection of a potential vehicle or driver problems that may be indicated by abnormities in multiple parameters when they are analyzed together. Furthermore, the lack of portable and scalable vehicle status and accident detectors often leads to overuse of emergency responder resources (e.g., emergency response professionals' time) which can be better spent on e.g., responding to more urgent or dangerous accidents, and the like.
An unfulfilled need exists for a means to enable continuous monitoring of vehicle status and the driver in a portable, easy-to-use manner.

Generally stated, a local device is configured in accordance with the present disclosure to detect a vehicle status, such as for example an accident or even unsafe driving conditions, and provide output signals to local and/or remote devices or indicators representative of vehicle data and vehicle status. A host system may include a central server configured to send and receive data to and from the device, and a user interface such as for example a hosted web site generated via the central server or a program application downloaded to and generated from a remote user device such as for example a smartphone, the user interface being optionally configured to display the vehicle data and status received from the local device and/or to receive remote user input for programming the local device. The local device may in various implementations be a dedicated or standalone device for use in (and powered by a power source associated with) a vehicle such as for example a cigarette lighter adapter as further described below, or may be a computing device having numerous alternative uses such as for example a smartphone running a dedicated program application.

As the local device protrudes outward from the cigarette lighter socket of a vehicle when it is plugged in, in other implementations (not shown) it may be desirable that the housing 12 include a bendable, rotatable or otherwise moveable portion which may allow an opposing or distal end of the housing 12 with respect to the cigarette lighter plug leads 14 to be positioned in a practical fashion and thereby accommodate varying vehicle interior designs. In such implementations, the moveable portion of the housing 12 may further include a locking mechanism such as a latch that prevents the moveable portion from moving relative to the first end (i.e., the cigarette lighter plug) once it is locked into position.

As previously described or otherwise implied above, a local device 10 in accordance with various implementations of the present disclosure may communicate and interact with other devices via a connector and/or cable such as for example a 30-pin cable or an embedded communications device such as an RF module. The device can communicate with a mobile cellular device, another device connected to an onboard vehicle data gathering module (e.g., via an OBD-II port as is known in the art), other sensor devices attached to the vehicle, and/or devices used to communicate with the driver in the vehicle. Interaction between a mobile cellular device and the local device 10 may be for the purpose of programming or setting up the local device 10 and/or viewing data from the local device 10. Interaction between a device connected to the OBD-II port and the local device 10 may further be established for the purpose of collecting data from the vehicle which would otherwise be unavailable but useful within the scope of the present disclosure, or even for the purpose of allowing the local device 10 to operate alternative vehicle functions such as for example the opening or locking of car doors, windows, trunk, etc. This data may include without limitation vehicle speed, airbag deployment, vehicle braking, and various additional information as may be supplied from the engine control unit (ECU).
Also as previously mentioned, the local device 10 may have a small button associated with the housing for user programming. Alternatively or in addition, it may be desirable to provide another physical input/output port on the device housing such as for example a USB port for external cable connection and programming, or even a USB cable connector integral with or otherwise for example extendable from the housing to establish a connection with a USB port of a programming device. However, in various implementations it may be desirable to omit such a physical programming mechanism and instead rely on wireless programming methods. One such method for programming the local device 10 may include accessing the hosted user interface (website) where some or all of the device/system parameters may be setup and then a message sent to the local device 10 to adjust the settings. This may generally involve providing a list of programmable settings for user selection, and subsequently providing either a data entry field or a series of user selectable parameters in association with each selected program setting. The predetermined contact information (e.g., telephone numbers) to be used by the local device in case of an accident or other predetermined extreme event via text messaging (e.g., SMS) can also be programmed through the website. The local device may further include an identification code and/or security code which is further entered via the website so that for example the website knows which device to program or confirms that authorization exists for the same.
In addition, or in the alternative, programming for the local device may be carried out via a mobile computing device such as for example a smartphone, for example wirelessly or using a hardware connector that is attached to the device. Setup proceeds in substantially the same manner or via similar pathway as that described with respect to the website. As an alternative to entering a device-specific code, there may in certain implementations be a predetermined radius of for example several feet around the local device where a remote device can auto-connect with the local device and allow programming through the local device's RF module (or equivalent). This auto-connect feature may be for example triggered by the depressing of a small-pin sized programming button on the device.
In various implementations, the local device may be programmed to continuously collect and transmit data associated with the vehicle to the host server for storage in the database. Further, the local device processes vehicle data to determine vehicle status conditions such as for example an emergency event/accident, or more broadly a driving status which may include safe, unsafe or merely cautionary status modes. In other implementations within the scope of the present disclosure, the vehicle status conditions may be determined remotely on for example the host server based on received data associated with the vehicle having been transmitted on a more or less continuous basis via the communications network.

The process may start (at step 102) upon power being initially provided to the local device via vehicle ignition, initial plug-in to the onboard power source, etc. Once power has been supplied to the device, the microcontroller waits for acceleration data to be received from the accelerometer of the local device (step 104). If the acceleration data is greater than a predetermined acceleration threshold of for example 3G's (i.e., “no” in response to the query of step 106), the process returns to step 104 and continues to monitor the acceleration data. If an acceleration reading (or alternatively a set of acceleration readings where the data may be averaged and filtered for any of various reasons) exceeds the acceleration threshold (i.e., “yes” in response to the query of step 106), the process continues to step 108 and the vehicle speed may be determined. In certain implementations the device may rather than relying on a predetermined acceleration threshold include neural network processing algorithms for recognizing vehicle acceleration patterns and comparing current vehicle acceleration data with an acceleration threshold that has been determined by the microcontroller, perhaps as adjusted from a predetermined initial acceleration threshold in view of the recognized patterns.
Upon determining a vehicle speed or a series of two or more vehicle speed readings (step 108) and storing the vehicle speed reading(s) (step 110), the process then determines whether the change in speed is consistent with an accident in view of for example a change in speed being greater than a second predetermined threshold (step 112). If the change in velocity is less than the second predetermined threshold (or for example where only one velocity reading has been taken and therefore no rate of change can be determined) the process is then directed to step 114. If a subsequent acceleration reading determines that the vehicle acceleration has dropped below the first threshold (i.e., “yes” in response to the query in step 114), the process continues by erasing the stored velocity data (step 116) and then returns to step 104. If the vehicle acceleration remains above the first threshold (i.e., “no” in response to the query in step 114) the process returns to step 108 and the microcontroller takes additional velocity readings.
If at any point a vehicle acceleration reading is determined to be greater than the first threshold and the change in vehicle velocity is determined to be greater than the second threshold (i.e., “yes” in response to the query in step 112) the process continues by acquiring position coordinates for the vehicle via the position sensor/GPS (in step 118) and then reporting the accident pursuant to programmed instruction by for example transmitting vehicle position data and other programmed data to predetermined personnel such as EMS, family, friends, etc. (in step 120). In this manner detailed feedback regarding specifics of an accident may be provided, such as for example how the accident occurred, the order and direction of impacts over the course of the accident. This information may be used to estimate likely injuries to passengers in the vehicle and assist emergency personnel in allocating resources for dispatch to the emergency site.
Various additional modes of operation as further described below but without limitation to the specific modes recited herein may be activated by the user via engaging of the main button on the device housing. The local device may be programmed to perform any one or more of the modes upon activation or engaging of the button based for example on user selections via either or both of the host website or a program application via a remote computing device (i.e., smartphone handset).
In one exemplary mode of operation, the local device may have been programmed to treat the button as a help button, wherein upon activation of the button by a user the local device transmits an SMS and/or email message to a predetermined number and/or address with for example an alert and the location of the vehicle as determined from the GPS receiver. In an implementation, activation of the button may automatically trigger a call to a public safety answering point (i.e., 911), which may be supplemental rather than merely an alternative to other predetermined contacts and/or addresses. The voice call may in fact be preferable over the SMS option as a mistaken activation of the button may be easily identified by the emergency personnel.
In another exemplary mode of operation, the local device may have been programmed to treat the button as a position indication and notification button, wherein upon activation of the button by a user the local device transmits a vehicle location as determined from the GPS receiver to a predetermined location such as for example a social networking site associated with the driver, a group, a destination, etc. In this manner a user that is running late for an event may notify others collectively without sending several individual text messages or email messages.
In another exemplary mode of operation, the local device may have been programmed to treat the button as a tracking toggle button, wherein upon engagement of the button by a user a tracking feature is successively activated and deactivated. The tracking feature may include continuous transmission of vehicle position data and any other appropriate data as received or determined by the local device to a remote site such as the host website. One example of a tracking feature may include the tracking of service personnel, where the local device is plugged into a service provider's vehicle and customers of the service provider who are waiting for service can use the host website (or alternatively a web portal associated with the service providers themselves where such features are appropriately established) to actively track the current status of the vehicle along a service route (for example) and better determine when they can expect service. In a second example, the local device may be plugged into a delivery vehicle (i.e., mail, FedEx) to facilitate the tracking of packages that have been confirmed as loaded onto the particular vehicle. The present status of the button (i.e., the underlying tracking feature) may be indicated to the user by for example a light or through the use of an audio signal via the speaker.
In another exemplary mode of operation, the local device may have been programmed to treat the button as a business mileage logging button, wherein upon engagement of the button by a user a business mileage logging feature is successively activated and deactivated. When the feature is activated, the local device may be programmed to send a message to a remote program that keeps track of business mileage. The message may include a current odometer reading, wherein the remote program can perform business mileage calculations based on a previous message and associated odometer reading. Alternatively, the local device may be programmed to begin tracking mileage upon a first engagement of the button, and upon a second engagement of the button to determine a mileage since the first engagement and to transmit a message including the determined mileage to a remote program.
In another exemplary mode of operation, the local device may be programmed to treat the button as an “I'm Lost” button, wherein upon engagement of the button by a user the local device transmits an email to a predetermined contact along with the vehicle location on a map and a request to call the user.
In another exemplary mode of operation, the local device may be programmed upon engagement of the button by a user to record a sound clip or sound message and subsequently to transmit the recorded sound clip or message to a predetermined destination such as for example one or more email addresses or a social networking site (i.e., Facebook, Twitter, etc.). The sound clip or message may be recorded for a pre-determined length of time after the button has been initially engaged, or alternatively the local device may be programmed to record a sound clip or message for as long as the button remains engaged by the user, either by remaining depressed or, as with the tracking feature, by remaining in a toggled “on” or “off” position.
In another exemplary mode of operation, the local device may be programmed upon engagement of the button by a user to transmit a message including vehicle location data received via the GPS receiver to a predetermined website. The website may be configured to generate and place a pin or equivalent indicator on an associated map upon receiving the message, wherein the user may later access the map and see and label the “pins” on the map without forgetting their location. The website may further associate other data such as for example a time stamp, a user identifier, voice clip taken from the device, etc., with the location “pin”.

The computer program product may upon execution by the device 54 generate a user interface on the associated display screen by which the various parameters for the program may be set by the user, as well as display collected vehicle data, vehicle status information and other visual indications or cues as programmed. An example of such a visual indication may be a current speed limit for a particular stretch of road which is recognized by the program based on a GPS-determined location and comparison of the location with that same location on a digital map having speed limit data, as may be further described below.

The previously described method 100 determined an accident based upon acceleration and rate of change in velocity readings that are consistent with an accident, and consequently with conditions under which airbag deployment would be expected in theory but without explicit confirmation. In an effort to eliminate false positives, the data from the accelerometer/gyroscope may be substantiated using the microphone to detect the impulse/noise physically generated by airbag deployment or an equivalent sound sufficiently representative of an accident. As embodied in the algorithms of the computer program product of the present disclosure, this allows for the mobile cellular device 54 to detect and explicitly confirm accidents where for example the airbag is in fact deployed, or at least is determined to have been employed with a substantially higher degree of certainty.
The process may begin in step 202 by confirming that the mobile device is in fact located in a moving vehicle. Since a mobile cellular device does not remain in a vehicle at all times, such an assessment is necessary to avoid false positives. This can be done by using the GPS receiver, accelerometer or various combinations of sensors to discern when conditions being experienced by the device are consistent with being in a vehicle. The real time detection of circumstances allows the application to run in the background of the mobile cellular device 54 without the program being executed to assess movements for potential crashes when otherwise not applicable. In an alternative implementation, however, this step may be omitted or skipped by programming the device to perform the vehicle status determination sequence only upon manual execution of the program by a user rather than automatically detecting vehicle movement.
In an effort to conserve battery life, in various implementations the accelerometer may be the only sensor that runs the entire time that the program product is engaged. Typically, when the program is passively running in the background it only draws data constantly from the accelerometer. The data from the accelerometer is used to determine when the device 54 (handset) is transported into the interior of a moving vehicle. This change in environment can be discovered using velocity and duration of velocity data, as the speed achieved in a moving vehicle coupled with the time spent at that speed is only rarely achieved outside of a moving vehicle. Velocity data can be garnered by integrating the acceleration data from the accelerometer as the area under the acceleration curve is the velocity.
However, while the accelerometer can detect changes in velocity it cannot detect absolute velocity without being made aware of initial velocity (a reflection of the unknown variable that results when integrating). This means that after the program is launched initial velocity will first need to be calculated by enabling the additional sensors (step 204) and then using the GPS receiver. Ideally, absolute velocity would only need to be calculated once when the program is initiated and after that point would be accurately updated using the accelerometer data. Due to accuracy issues, however, using the accelerometer data alone is not sufficient to maintain accurate absolute velocity. In order to maintain a precise velocity value over time, the initial velocity may be updated via the GPS receiver. This update process may happen based on a set value that determines how often this occurs, such as for example every ten minutes. Assuming that the accelerometer data indicates the device is in a moving vehicle, the other sensors will start collecting data to aid in the full functioning of the application.
Even when the program is executed and fully functioning in “active mode,” it may continue to check data from the sensors to confirm that it is, in reality, in a moving vehicle (step 206). This continuous checking serves at least two purposes—it confirms that the judgment to turn on all of the sensors based on accelerometer data was accurate, and further triggers the program to turn off the sensors when the data from the sensors indicates that it is no longer in a vehicle (step 208). Upon the sensors determining collectively that the device is no longer in a vehicle (or never in fact was), the program returns to passive mode where it only draws data from the accelerometer.
The process of returning the program to passive mode may in various implementations require that the data from the sensors have determined that the device is not in a moving vehicle for some predetermined period of time. This substantially serves to prevent the program from returning to passive mode in congested traffic or other routine stops along the road.
In an alternative implementation, the process of returning the program to passive data may include a step of determining the user is in a position associated with the location of a road. This may be performed by for example using map data which has been previously downloaded to the associated device, or receiving signals from a remote server having performed the step which are representative of the user being on or off of such a position. If the determined position of a user does not coincide with a mapped road location, the process may either determine that the user is not in a moving vehicle based on the determined position alone, or may seek confirmation prior to returning to passive mode, such as for example based on the aforementioned movement data results.
The process continues in step 210 when a sound has been detected by the program as being consistent with airbag deployment in the vehicle, while the program is in active mode. The noises/impulses that the microphone detects can be interpreted in two fashions, by analyzing the sound signature (or sound signal) or by detecting the occurrence of a given threshold (measured in for example decibels—dB—as is conventionally known in the art). The more complex method of sound evaluation involves matching the sound signature collected by the microphone to that of a sampling of airbag detonation sound profiles. The more simplistic method of sound evaluation requires a threshold dB to be reached to conclude that the airbag has been deployed. Due to the extremely loud nature of airbag deployment, the noise can be uniquely identified by a threshold. Airbag deployment generates peak pressures between 167 and 173 dB which are higher than a typical mobile cellular device such as for example an iPhone can register. This means that in the event of airbag deployment the device's microphone will be saturated (for example, the current version of the iPhone's microphone saturates at 120 dB). Similar to the iPhone, most cellular phones do not contain microphones that are sensitive enough to accurately measure the pressures/impulses/noises generated by airbag deployment. This means that the microphone in the cellular device 54 can saturate when events other than an airbag deployment occur, and further explains why sound detection may desirably be used in conjunction with other data points to detect a crash.
Therefore, in step 212 the process continues by confirming the accident reading via other device sensors such as the accelerometer, in a manner which in various implementations may be substantially equivalent to that of the process 100 described above.
If the detected accident condition is not confirmed by other sensors (i.e., “no” in response to the query of step 214) the process returns to step 206. If the detected accident condition is in fact confirmed by other sensors (i.e., “yes” in response to the query of step 214) the process continues to step 216 and the program is triggered to report the accident in a manner which in various implementations may be substantially equivalent to that of the process 100 described above.
In accordance with implementations of the present disclosure as described above, the algorithm that assesses accidents may further apply a probability algorithm to maximize the efficacy of accident detection. Different values are assigned to the various sensors which are included and activated at a given time, and their respective indications. This may reduce the likelihood of accidents going undetected where not all of the sensor inputs indicate the certainty of an accident, while at the same time substantially avoiding false positives.
In another implementation, a real time feedback method in accordance with the present disclosure may deliver audible and/or visual cues to a driver after an unsafe driving maneuver has been detected. Regardless of whether the local device 10 as a cigarette lighter adapter or the mobile cellular device 54 using the computer program product is being utilized in accordance with the present disclosure, the vehicle status may include a determination of whether or not the driver is adhering to “safe” driving practices based on for example a comparison of detected vehicle speeds and/or acceleration with predetermined safety thresholds. Where a mobile cellular device 54 is used to execute the program, or is otherwise available and communicating with a local device 10, the visual cues may be displayed on the display for the device, possibly by flashing an icon or a colored screen. The audible alert, projected out over the speaker built into the handset, may generally be a safer way to cue the driver to risky driving behavior as the audible alert does not require the driver to avert their eyes from the road.
Referring now to
In step 306, the method continues by determining whether or not abrupt changes in velocity or acceleration have exceeded a predetermined threshold (safety limit). In the implementation shown, the primary sensor at work in assessing dangerous driving conditions is generally the accelerometer, as it may easily detect both abrupt increases and decreases in velocity (i.e., high magnitude acceleration or deceleration) as key indicators of unsafe driving. Alternatively or in addition, the GPS receiver may be utilized to provide safety feedback by detecting vehicle speeds.
If the change in velocity or acceleration is determined to have been greater than the predetermined threshold (i.e., “yes” in response to the query in step 306), the method proceeds to step 308 and an unsafe driving alert is generated for the benefit of the driver, which may be visually and/or audibly generated and provided as previously described. The number of unsafe driving alerts is subsequently incremented (N=N+1) in step 310 and then the new number of unsafe driving alerts is compared to predetermined threshold number of alerts (step 312). If the number of unsafe driving alerts that have been generated during a single driving session exceeds the predetermined threshold (i.e., “yes” in response to the query in step 312), the method may in various implementations proceed by generating and transmitting correspondence such as for example an email or SMS notification to a predetermined third party regarding the number of unsafe driving alerts. The email or text message may include for example the date, time, location, user name, type of unsafe driving practice (where available), number of unsafe driving alerts (N), or any of various other user-selectable options.
If the change in velocity or acceleration is determined to have been less than the predetermined threshold (i.e., “no” in response to the query in step 306), the method instead proceeds to step 316 and a stored speed limit is obtained with respect to a current position for the vehicle, as determined from the position data. The stored speed limit may be obtained from a digital map or the like which may further be stored in a remote database which is continuously accessed via a communications network, or at least relevant portions of the map may be stored in a memory on the device 10, 54. Where a speed limit is not stored for the current position, this step can obviously be skipped or omitted. Where a speed limit is available, however, the method then includes comparing the instantaneous velocity of the vehicle with the obtained speed limit for the instantaneous position (step 318) to determine if an unsafe driving event is occurring.
In various implementations, the obtained speed limit may be incremented by a predetermined “offset” or “buffer” amount which may be set as a percentage (e.g., 10%) or an absolute number (e.g., 10 MPH) such that the comparison is actually between the instantaneous velocity of the vehicle and a value corresponding to the buffered speed limit.
If the instantaneous velocity is greater than the stored speed limit, or otherwise the stored speed limit with the predetermined buffer amount applied thereto (i.e., “yes” in response to the query in step 318), the method proceeds to step 308 and continues as previously described. If the instantaneous velocity is less than the stored speed limit, or otherwise less than the stored speed limit with the predetermined buffer amount applied thereto (i.e., “no” in response to the query in step 318), the method instead moves on to step 320 and the device/program may transmit the movement data and position data to a remote server such as for example the host server as described above. In various implementations the movement data and position data may be stored locally, collected and transmitted at periodic intervals rather than continuously transmitted. Finally, the method may (in step 322) confirm that the vehicle is still in transit or otherwise that the real time feedback program is still active or enabled, consistent with the battery conservation method as previously described.
As described above, speed limit data may be obtained from a remote server and associated database. In accordance with the present disclosure, the remote database may in certain implementations include raw data which has been received or otherwise acquired from a third party such as for example the Department of Transportation (DOT). By doing this for every state a complete database of road speed limits can be acquired and used to populate a hosted or otherwise central remote database for use in real time driver feedback. The database may be considered to have substantially correct speed limits in such cases, but some of the speed limits may become outdated during the time between database updates being performed by the associated agency.
In various implementations other factors may come into play in determining unsafe driving maneuvers or circumstances. For example, the vehicle may have sensors or equivalent mechanisms for detecting conditions such as for example nighttime conditions, less-than-desirable weather conditions such as fog, rain and snow, or congested traffic conditions which might heighten the negative effects from unsafe driving. The method 300 may in such implementations be supplemented in terms of the number of steps or otherwise to modify the various thresholds in order to account for the various non-optimal driving conditions and provide alerts as appropriate.
Referring now to
The method 400 includes a first step 402 of populating the host database with speed limit data from a third party source such as for example the DOT. It may be understood that while a continuous update is preferable, this step may generally not be performed on any kind of a continuous basis, but rather in accordance with an expected update period as provided by the third party. Where the third party may for example update speed limits as they become known rather than provide periodic updates to the entire database, the host server may be programmed to request speed limit updates from the third party at predetermined intervals to encompass changes that have been made in the interim.
The host server then receives movement data and position data from a vehicle source (step 404, see also step 320 of
The stored movement data may be aggregated (in step 408) with other movement data having been previously received and stored with respect to the same location or associated locations (such as an equivalent stretch of road) to generate for example an average and a median speed recorded from that particular location, while still maintaining the individual data points. In various implementations the movement data may be dated and/or other data of interest appended to the stored data entries, such that for example speed limit data from the third party source that is received on a particular date is not revised in view of vehicle data that was previously received and stored. It may be desirable to eliminate data points that are recorded as having been stored for more than a predetermined amount of time, being for example greater than the interval for updating the database with data from the third party source, which may reduce the potential effect of old readings on aggregate.
If a concentrated number of drivers in a particular area provide device input, then the host database may be updated in near real time for that particular area. This is possible because the average speed, disregarding outliers, on a given road would theoretically be consistently deviant from a posted maximum speed limit. Outliers may be eliminated or otherwise disregarded (in step 410) in accordance with a first threshold deviation value with respect to the remainder of the movement data stored in the host database for a particular location/area.
The deviation value may be determined by analyzing the aggregated movement data from the plurality of vehicle inputs with respect to a location/road with a known speed limit. If data points on a given road are found to be outside of a normal or expected range for the particular speed limit as indicated by the third party source, the host server may act by adjusting the speed limit data in the database (step 412). The determination may further include confirming that the plurality of vehicle inputs satisfy at least a threshold degree of confidence, such that for example a sufficient number of readings are available or that the number of readings are within a narrow enough band to instill a minimal degree of confidence as needed to support maximum speed limit adjustment in accordance with the present disclosure.
Recall that in describing the real time driver feedback method 300, the process included a step (316) of obtaining a stored speed limit for a current position, and the stored speed limit may be offset by a predetermined offset or buffer value which may be an absolute offset value or a percentage offset with respect to the stored speed limit. In various implementations, the local device 10 or mobile cellular device 54 running a computer program product in accordance with the present disclosure may obtain an adjusted speed limit value from the host server as derived using the speed limit database updating method 400 as further described herein. In this case, the buffer value may become redundant, as the updated speed limit value inherently represents a safe driving speed range as determined from the various data points received, stored and aggregated by the host server in association with that particular area, which accounts for the buffer value itself with respect to the underlying fixed speed limit. For example, while generally stated a road having a 55 MPH speed limit may nevertheless be safely navigated at 62 MPH in which case a buffer is desirable to prevent unsafe driving alerts at such speeds, a particular stretch of the road may have blind spots, tight curves, or the like, which would eliminate the desirability of using a buffer in such cases.
Another case where the buffer value may be considered redundant is where a process in accordance with the present disclosure is able to rely on information from a sufficient number of vehicles on a particular road in real time. In this case, real time traffic information may affect the determination of an unsafe driving alert where for example the various vehicles are traveling at a mean or median speed with a relatively small deviation (e.g., less than a predetermined deviation threshold or otherwise within an associated range based on the detected speeds and a predetermined deviation). A subsequent determination that a particular user/driver is traveling within the associated range may in such an implementation be considered to overrule an otherwise unsafe driving condition, as the driver would be permissibly traveling within the flow of traffic.
In certain implementations, a road safety mapping method may further be performed by a program executed from the host server, which may be a subset of the speed limit database updating method or otherwise independently executed. Such a method includes an algorithm for monitoring accidents and other unsafe driving events (e.g., extreme acceleration/deceleration events) as derived in accordance with methods previously described above. The events may be archived on the host server or equivalent remote central server. Overlaying the database of extreme events collected from the various users of the host system on a map using geo-coordinates, tagged to the events, generates a safety map. The safety map indicates locations where users/drivers have had accidents or otherwise generated unsafe driving alerts such as where they have been determined to have accelerated or decelerated in an extreme fashion. Knowledge of this aggregated data allows users with access to it to avoid dangerous roads or junctions when possible and to be extra alert when having to navigate them. After a large sample of data has been collected, road sections and intersections can be mapped in colors indicating their riskiness, much like traffic status is currently depicted on may global positioning systems.
In an implementation, systems and methods in accordance with the present disclosure may further be able to provide audio and/or visual alerts to a user indicating that a relatively unsafe stretch of road is upcoming or otherwise anticipated (based, e.g., on current heading, speed, alternative roads).
In an implementation, systems and methods in accordance with the present disclosure may implement a road safety mapping method as described above to determine that unsafe driving practices were used by a driver with respect to a particular stretch of road, even where not otherwise accounted for by the available speed limit data.
In an implementation, systems and methods in accordance with the present disclosure may further implement a road safety mapping method as described above to generate an optimal route between a starting point and an ending point based upon a number of criteria, which may include for example and without limitation an estimated amount of time needed to navigate each of a plurality of routes and a road safety value for each route. The road safety value may be determined by for example aggregating a number of dangerous locations along the route in accordance with predetermined weighting factors. The road safety value may further account for a number of times the driver has been recorded as previously traveling the given route, or data indicating road construction or other current road data that requires accounting.
Once a comprehensive database of road safety data is compiled insurance companies may be able to for example evaluate insurance rates taking into consideration the risk of the roads upon which the policy holder drives.
While the disclosure has been described in terms of exemplary implementations, those skilled in the art will recognize that the disclosure can be practiced with modifications in the spirit and scope of the appended claims. These examples are merely illustrative and are not meant to be an exhaustive list of all possible designs, implementations, applications or modifications of the disclosure.
