This description relates to techniques for controlling the transmissions of operational information from vehicles for remote processing and analysis.
With the increased interest in reducing dependency on fossil fuels, the use of alternative energy sources has been incorporated into various applications, such as transportation. Both public and private transportation vehicles have been developed to run on fuels other than traditional petroleum based fuels (i.e., petrol, diesel, etc.). Some vehicles solely use alternative energy sources while others combine the functionality of petroleum based systems with alternative energy based systems (e.g., electrical, biofuel, natural gas, etc.). Along with being potentially more cost-effective and having more abundant resources, such alternative energy sources and their byproducts are considered to be more environmentally friendly.
The systems and techniques described herein relate to controlling the transmission of operational information from a vehicle to one or more external locations. Through collecting, processing and managing such information, data can be used to develop custom real world fuel saving strategies, to provide service insights so that technicians can be better prepared to service a vehicle prior to having direct access to the vehicle, and to keep customers abreast of fault codes, vehicle behavior, maintenance issues, etc.
Various implementations provide computing device-implemented methods. The methods include receiving data that represents a time interval for data capture, receiving time stamped operational parameter data of a vehicle, where the time stamped operational parameter data is captured at a frequency corresponding to the time interval, selecting vehicle inspection data from the time stamped operational parameter data, where the selected vehicle inspection data being collected during an inspection time frame defined by an event associate with the vehicle, compressing the vehicle inspection data selected from the time stamped operational parameter data, and transmitting the compressed vehicle inspection data to a server system remote from the vehicle.

The compressed vehicle inspection data includes time stamped operational parameter data from the vehicle selected from a data set and selected based on an inspection time frame window. The compressed vehicle inspection data includes time stamped operational parameter data having a time stamp within a pre-specified range of a time of the vehicle fault.
In some implementations, diagnosing the vehicle fault comprises analyzing a drive cycle of the vehicle.
In certain implementations, receiving compressed vehicle inspection data includes receiving performance specification corresponding to a drivetrain of the vehicle.

Referring to
Under some conditions, analysis of the operational information may suggest that particular vehicles, types of vehicles, etc. may be optimum. For example, some environments and driving conditions may be better suited for conventional internal combustion engine based vehicles, while alternative fuel vehicles, which may solely rely upon non-petroleum energy sources (e.g., electricity, natural gas, biofuels etc.), may be better suited for other environments. Other vehicles that may prove to be optimum may include hybrid vehicles that employ two or more distinct power sources (e.g., an electric motor and an internal combustion engine—referred to as a hybrid electric vehicle or HEV). Some hybrid vehicles (referred to as plug-in hybrid vehicles) may operate by using energy storage devices that can be replenished (e.g., rechargeable batteries). In some arrangements, for electrical energy storage devices, one or more techniques may be implemented for charging and recharging the devices. For example, batteries may be charged through regenerative braking, strategic charging techniques, etc. during appropriate operating periods of the vehicle. In general, energy is typically lost as heat in conventional braking systems; however, a regenerative braking system may recover this energy by using an electric generator to assist braking operations. Some systems and techniques may also strategically collect (e.g., leech) energy from the combustion engine during periods of efficient operation (e.g., coasting, traveling, etc.) and later assist the engine during periods of lesser efficiency. For such vehicles, the electric generator can be a device separate from the electric motor, considered as a second operating mode of the electric motor, or implemented through one or more other techniques, individually or in combination. Energy recovered by regenerative braking may be considered insufficient to provide the power needed by the vehicle. To counteract this lack of energy, the electric motor may be engaged during defined periods to assist the combustion engine or to be the sole source of propulsion. One or more control strategies may be used to determine these time periods. Similarly, periods of time may also be determined to engage regenerative braking and strategic charging in order to replenish energy storage. Other operations of the vehicle (e.g., accelerate, decelerate, gear changes, etc.) may also be defined for the control strategies. By developing such strategies to control the assistance provided to combustion engines (e.g., during low efficiency periods), energy may be conserved without negatively impacting vehicle performance. Along with such strategies, individual vehicles, types of vehicles, etc. may be selected for use based on the operational environment.
Some vehicle manufacturers may recommend operations and control strategies for entire classes of vehicles or other types of large vehicle groups (e.g., same model vehicles, same vehicle line, etc.) at particular times (e.g., at the release of the vehicle line). Similarly, the level of assistance provided by an electric motor or other type of alternative fuel system may be constant. Being rather static, such recommendations do not account for the environment in which the vehicle is operated. Route specific information (e.g., vehicle is driven under highway, city, rural, etc. conditions), driver information (e.g., driver accelerating and braking tendencies, etc.), and other types of environmental information (e.g., time of day, season, etc.) are not accounted for in determining the appropriate operational strategies. Furthermore, vehicle selection is typically determined without consulting such route and environmental information. Typically a vehicle is selected absent this information because there is no other option (e.g., the driver has access to a single vehicle) or no information is provided for vehicle management (e.g., a vehicle is randomly assigned to a driver, such as a delivery truck). Absent taking steps to attain, analyze, and use such information for vehicle selection, poor performance may occur along with related negative impacts (e.g., reduced fuel efficiency, increased operating costs, etc.). One or more techniques may be implemented for appropriately selecting a vehicle, type of vehicle, etc. for operating in a particular environment. For example, data reflective of vehicles operating in the environment may be used for selecting a vehicle, which type of vehicle, etc. Vehicle selection may also identify that one vehicle type (e.g., a combustion engine based vehicle) should be converted into another vehicle type (e.g., hybrid vehicle) to improve performance (e.g., fuel efficiency, costs, etc.). Such operational data from vehicles may be used for other types of analysis. For example, vehicle operational data may be used for analysis to improve recommended operations and control strategies for a vehicle, type of vehicle, etc. For example, hybrid conversions may be more advantageous (e.g., reduced fuel consumption) for lower speed environments and less advantageous in high-speed environments.
One or more techniques may be employed for making such selections or other types of analysis. For example, from the vehicle operational parameters (e.g., operating speed, fuel economy, etc.) one or more metrics (e.g., performance metrics) may be calculated. In turn, the metrics may be utilized for further analysis. For example, along with using the information for vehicle selection, vehicle type selection, etc., converting one vehicle type (e.g., a combustion engine based vehicle) into another vehicle type (e.g., hybrid vehicle) may be determined through use of the operational parameters and metrics to achieve performance improvements in fuel efficiency, costs, etc.
As shown in
In some situations, data from sources other than the vehicle may also be collected. For example, user input may be provided. In this arrangement, the vehicle 100 includes an electronic display 106 that has been incorporated into its dashboard to present information such as selectable entries regarding different topics (e.g., operator ID, planned vehicle operations, trip destination, etc.). Upon selection, representative information may be gathered and provided to the vehicle information manager 102. To interact with the electronic display 106, a knob 108 illustrates a potential control device; however, one or more other types of devices may be used for user interaction (e.g., a touch screen display, etc.). Similar to using one or more sensors to collect operational data, other types of information may also be gathered; for example, a sensor 110 (here embedded in the dashboard of the vehicle 100) may collect information such as cabin temperature, location of the vehicle (e.g., the sensor being a GPS receiver) and other types of information. By collecting information such as GPS location, additional information may be provided to the vehicle information manager 102 (e.g., current location, start location, destination information) which may be used for quantifying vehicle performance. In some arrangements, information from other vehicles may be used by the vehicle information manager 102. For example, data may be collected from a fleet of vehicles (e.g., similar or dissimilar to the vehicle 100) and used, for example, in data comparisons. While one sensor 110 is illustrated in this example, multiple sensors may be located internally or externally to the vehicle for information collection (e.g., internal or external temperature or various vehicle components, etc.). One or more devices present in the vehicle 100 may also be used for information collection; for example, handheld devices (e.g., a smart phone 112, etc.) may collect and provide information (e.g., location information, identify individuals present in the vehicle such as vehicle operators, etc.) for use by the vehicle information manager 102 (e.g., identify driving characteristics of a vehicle operator). Similarly, portions of the vehicle itself (e.g., vehicle components) may collect information for the vehicle information manager 102; for example, one or more of the seats of the vehicle 100 (e.g., driver seat 114) may collect information (e.g., position of the seat to estimate the driver's weight) to provide to the vehicle information manager 102. Similar to data directly provided by one or more sensors, processed data may also be provided to the vehicle information manager 102. For example, gathered information may be processed by one or more computing devices (e.g., controllers) before being provided to the vehicle information manager 102.
In some arrangements, along with collecting information at the vehicle, remotely located information sources may be accessed by the vehicle. Once the vehicle information is collected, the data may be prepared and transmitted by the vehicle information manager 102 (along with assistance from the controller 104) to one or more locations by employing one or more communication techniques and methodologies. For example, wireless communication techniques (e.g., radio frequency, infrared, etc.) may be utilized that call upon one or more protocols and/or standards (e.g., the IEEE 802.11 family of standards such as WI-FI, the International Mobile Telecommunications-2000 (IMT-2000) specifications such as 3rd generation mobile telecommunications (3G), 4th generation cellular wireless standards (4G), 5th generation cellular wireless standards (5G), wireless technology standards for exchanging data over relatively short distances such as BLUETOOTH, etc.). While the figure illustrates the vehicle information manager 102 (and the controller 104) as being entirely located onboard the vehicle 100, some or all of the functionality of the vehicle information manager 102 may be provided from one or more other locations (including remote locations). In one such arrangement, vehicle equipment (e.g., sensors) may provide (e.g., stream) raw data to a remotely located vehicle information manager by employing one or more communication techniques and methodologies.
Referring to
In some arrangements, the network architecture may be considered as including one or more of the vehicles. For example, vehicles may include equipment for providing one or more network nodes (e.g., supply truck 208 functions as a node for exchanging information between the supply truck 210 and the network 204). As such, the information exchanging capability may include the vehicles exchanging information with the vehicle information service provider 202 and other potential network components (e.g., other vehicles, etc.).
One or more technologies may be used to exchange information among the vehicle information service provider 202, the network 204 (or networks) and the collection of vehicles. For example, wireless technology (capable of two-way communication) may be incorporated into the vehicles to exchange information with the vehicle information service provider 202. Along with providing and collecting information (e.g., operational parameters) from the vehicles, the vehicle information service provider 202 may be capable of processing information (e.g., in concert with a vehicle data analyzer 214 to analyze data (e.g., determine vehicles for possible selection, conversion, etc.) and executing related operations (e.g., store collected and processed information).
In some arrangements, the vehicle information service provider 202 may operate as a single entity; however, operations may be distributed among various entities to provide the functionality. In some arrangements, some functionality (e.g., operations of the vehicle data analyzer 214) may be considered a service, rather than a product, and may be attained by entering into a relationship with the vehicle information service provider 202 (e.g., purchase a subscription, enter into a contractual agreement, etc.). As such, the vehicle information service provider 202 may be considered as being implemented as a cloud computing architecture in which its functionality is perceived by users (e.g., vehicle operators, business operators, vehicle designers and manufacturers, etc.) as a service rather than a product. For such arrangements, users may be provided information (e.g., vehicle or vehicle type selections for operating in particular environments, vehicle selections for conversion into hybrid vehicles, etc.) from one or more shared resources (e.g., hardware, software, etc.) used by the vehicle information service provider 202. For service compensation, one or more techniques may be utilized; for example, subscription plans for various time periods may be implemented (e.g., a time period for monitoring use of vehicles or vehicle types in particular environments, analyzing if new technology should be incorporated into or used to replace vehicles, etc.).
Along with information being provided by one or more vehicles (e.g., received through the network 204, etc.), the vehicle information service provider 202 may utilize data from other sources. For example, information sources 216 external to the vehicle information provider 202 may provide vehicle related information (e.g., manufacturer recommendations for performance, vehicle load conditions, etc.), environmental information (e.g., current road conditions where the vehicle is operating, traffic conditions, topographical information, weather conditions and forecasts, etc.). In some arrangements, the information sources 216 may be in direct communication with the vehicle information service provider 202; however, other communication techniques may also be implemented (e.g., information from the information sources 216 may be provided through one or more networks such as network 204).
In the illustrated example, to provide such functionality, the vehicle information service provider 202 includes a server 218 that receives information via the network 204 and the information sources 216. Additionally, the server 218 is illustrated as being in direct communication with a storage device 220 that is located at the vehicle information service provider 202 (however, remotely located storage may be accessed by the server 218). In this example, the functionality of the vehicle data analyzer 214 is located off-board the vehicle while the functionality of the vehicle information manager 102 (shown in
Referring to
The vehicle information manager 102 may implement one or more techniques to improve the efficiency of transmitting information from the vehicle. For example, rather than simply transmitting all of the data (e.g., operational parameters) collected from the vehicle (by the data collector 300), techniques may be employed to reduce the amount of potentially unneeded transmissions and thereby improve efficiency and reduce costs. For example, rather than transmitting collected information at a relatively constant rate (e.g., as each segment of data is ready for transmission), one or more events may be defined and used as triggers for transmitting data. Such events may be associated with situations that occur during the operation of the vehicle 210 (although events may also be defined for situations that occur off-board the vehicle). In one instance, an event could be defined by one or more predefined rules associated with operations of the vehicle, activities detected in the vehicle, etc. For example, attaining a particular speed, acceleration, deceleration, fuel consumption level, etc., can be considered such an event, which triggers the transmission of information (e.g., time series data of the speed, acceleration, etc.) to one or more locations (e.g., the vehicle information service provider 202). Events may also be associated with vehicle location, route being driven, etc. For example, based upon the GPS coordinates of the vehicle, travel direction, etc., the vehicle may stray from a predefined route and more information may be sent from the vehicle to the service provider 202. Activities of the vehicle driver may also be used to define one or more events. For example, displacement of the vehicle's accelerator pedal, brake pedal, etc. (due to the driver) may extend beyond a predefined amount and trigger the transmission of information from the transceiver 302. Detecting such predefined events may be implemented by employing one or more techniques, for example, the vehicle information manager 102 may include an event detector 304. In this arrangement, information such as operational parameters (e.g., collected by the data collector 300) is monitored by the event detector 304 to determine if one or more rules have been satisfied to declare a predefined event (or multiple events) as being detected. In some arrangements, the event detector 304 may use a series of predefined rules (e.g., “vehicle speed has exceeded 80 mph”, “battery charge is below 20%”, etc.) to determine if one or more events has occurred. In some arrangements, multiple rules may need detection before an event is considered to have occurred. For example, rules may reflect hysteresis by depending upon both current conditions of the vehicle and past conditions. To assist the operations of the event detector 304, the transceiver 302 and the data collector 300, one or more data storage techniques may be employed by the vehicle information manager 102. As illustrated, one or more storage devices (e.g., memory components, hard drives, etc.) such as storage device 306 may be included in the vehicle information manager 102. Also with assisting with the operations of the information manager components, the storage device 306 may also be considered as providing a data store for information such as operational parameters (collected during the operation of the vehicle) that can be later accessed. For example, after traveling its route, collected data may retrieved from the storage device 306 (e.g., by the vehicle owner, the vehicle information service provider 202, etc.) for analysis to quantify performance, to compare performance with other vehicles, etc.
Once a predefined event or multiple events have been detected (e.g., by the event detector 304), one or more type of changes may be introduced for transmitting data from the vehicle 210 to one or more locations (e.g., the vehicle information service provider 202). In one arrangement, upon detection the amount of information being transmitted increases, e.g., to allow for a more detailed analysis to be performed (by the vehicle information service provider 202). To increase the amount of information, one or more techniques may be utilized such as including more information in transmissions. For example, different information (e.g., a time series of pedal displacement) may be transmitted based upon the event detected (e.g., the vehicle brake pedal being abruptly stepped on by the driver). In some arrangements, this additional data to be included in transmissions may be defined along with the event. Data transmission properties may also be changed upon the detection of an event (by the event detector 304) to increase the amount of information being sent. For example, prior to detection, information may be transmitted (e.g., from the transceiver 302) at one frequency and post detection the transmission frequency may be increased (e.g., for a period of time). Bursts of information may be sent from the vehicle to the vehicle information service provider 202 due to event detection. Similar to adjusting transmission characteristics for a single period of time (e.g., increase transmission frequency for a period of time and then return to the original transmission frequency), such characteristics may be periodically adjusted. For example, based upon an event being detected, a repetitive sequence of higher transmission frequency periods followed by lower transmission frequency periods may be employed by the transceiver 302. As such, a sequence of information bursts followed by periods of less information being transmitted may be utilized for efficient data transfer. Similar to frequency, other transmission properties involving compression, modulation schemes, etc. may be changed due to the detection of an event (by the event detector 304).

These computer programs (also known as programs, software, software applications or code) include machine instructions for a programmable processor, and can be implemented in a high-level procedural and/or object-oriented programming language, and/or in assembly/machine language. As used herein, the terms machine-readable medium and computer-readable medium refer to a computer program product, apparatus and/or device (e.g., magnetic discs, optical disks, memory, Programmable Logic Devices (PLDs)) used to provide machine instructions and/or data to a programmable processor, including a machine-readable medium that receives machine instructions.
To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for presenting data to the user, and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well. For example, feedback provided to the user can be a form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback). Input from the user can be received in a form, including acoustic, speech, or tactile input.
The systems and techniques described here can be implemented in a computing system that includes a backend component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a frontend component (e.g., a client computer having a user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described here), or a combination of such backend, middleware, or frontend components. The components of the system can be interconnected by a form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network (LAN), a wide area network (WAN), and the Internet.
The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
In some implementations, the engines described herein can be separated, combined or incorporated into a single or combined engine. The engines depicted in the figures are not intended to limit the systems described here to the software architectures shown in the figures.
A number of embodiments have been described. Nevertheless, it will be understood that various modifications can be made without departing from the spirit and scope of the processes and techniques described herein. In addition, the logic flows depicted in the figures do not require the particular order shown, or sequential order, to achieve desirable results. In addition, other steps can be provided, or steps can be eliminated, from the described flows, and other components can be added to, or removed from, the described systems. Accordingly, other embodiments are within the scope of the following claims.
Also, the technology described herein may be embodied as a method, of which at least one example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, implementations may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative implementations.
The claims should not be read as limited to the described order or elements unless stated to that effect. It should be understood that various changes in form and detail may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims. All implementations that come within the spirit and scope of the following claims and equivalents thereto are claimed.
