Patent Application
20170068245
Many users utilize vehicles that operate in an autonomous and/or a semi-autonomous manner (e.g., parking assist, lane assist, etc.). In an example, some autonomous vehicles have the ability to transport users from one location to another location with minimal to no user involvement. In doing so, autonomous vehicles may be configured to make a majority of the operational decisions for the user. However, many users may desire to have the ability to control various aspects of how the autonomous vehicle operates, such as those users that have been accustomed a certain driving style, route, driving speed, etc. Unfortunately, users may not be able to efficiently and/or effectively control such operational aspects. As a result, autonomous vehicles may leave users feeling as if they have little to no control over the manner in which the autonomous vehicles operates.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
Among other things, one or more systems and/or techniques for operating an autonomous vehicle are provided herein. In an example, a driving profile, comprising a driving preference (e.g., a speed preference, a route preference, etc.) of a user, may be received by an automated driving component of the autonomous vehicle. In an example, the driving profile may be received, through a communication connection (e.g., Wi-Fi connection, Bluetooth connection, a cellular connection, etc.), from a remote driving preference provider (e.g., a storage component hosted on a cloud based server and/or a mobile device configured to store and/or provide access to driving profiles of the user). The driving profile may be evaluated to identify the driving preference of the user. An operational parameter for the autonomous vehicle may be generated based upon the driving preference of the user. In an example, a route to a destination may be generated based upon the driving preference. The autonomous vehicle may be operated based upon the operational parameter. In an example, the autonomous vehicle may be operated to travel along the route based upon the operational parameter (e.g., maintain a particular speed with respect to a posted speed limit; avoid bridges; avoid lane changes; etc.).
In an example, a condition of the user traveling in the autonomous vehicle may be determined (e.g., is the user calm, is the user stressed, etc.). The condition may be determined by evaluating biometric data corresponding to the user. In an example, the biometric data may comprise heartrate data, body temperature data, skin conductance data, voice stress level data, brainwave data, and/or blood alcohol level data. The operational parameter for the autonomous vehicle may be adjusted in response to the condition of the user not corresponding to the driving preference of the user (e.g., determining if the condition of the user corresponds to a condition associated with the driving preference; by way of example, a low stress state may be associated a low speed preference or a high speed preference may be associated with an emotionally high state). In another example, the route to the destination may be adjusted to generate an adjusted route in response to the condition of the user not corresponding to the driving preference of the user (e.g., the route may be adjusted based upon the condition of the user indicated the user is becoming stressed as a result of being stuck in traffic).
To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages, and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.
The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth to provide an understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are illustrated in block diagram form in order to facilitate describing the claimed subject matter.
One or more systems and/or techniques for operating autonomous vehicles are provided herein. Users may have a desire to control the manner in which autonomous vehicles are operated, such by adjusting an operational speed, a tailgating distance (e.g., bumper to bumper distance between two cars), a fuel performance characteristic, etc. of autonomous vehicles. Unfortunately, such control capabilities may not be available in autonomous vehicles, and control systems that operate autonomous vehicles may lack technology for allowing users to adequately customize how the autonomous vehicle operates. As provided herein, a driving preference (e.g., a route preference, a speed preference, a full consumption preference, a tailgating preference, a lane preference, etc.) of a user may be provided to an automated driving component of an autonomous vehicle. An operational parameter for the autonomous vehicle may be generated based upon the driving preference of the user. The autonomous vehicle may be operated based upon the operational parameter (e.g., the operational parameter may be used to control the operation of the autonomous vehicle, such that the autonomous vehicle operates and/or performs in accordance with the driving preference).
By providing functionality for controlling various aspects of the operation of autonomous vehicles, users may be able to better utilize the functionality of autonomous vehicles, as well as benefit from an enhanced user experience therewith. For example, with increased control over the operation of autonomous vehicles, users may be able to more effectively and efficiently operate autonomous vehicles based upon the needs of a user and/or the functionality the user may desire to optimize (e.g., increased fuel economy for long drives, increased power output when hauling heavy loads, increased tailgating distance on icy roads, reducing stress by avoiding high traffic routes, etc.). Accordingly, operating efficiency, functionality, and/or power consumption of autonomous vehicles may be improved and more fully utilized by providing users with an increased ability to control autonomous vehicles, such as through the use of driving profiles. Furthermore, by maintaining driving profiles on a remote preference provider, users may be able to efficiently store, update, and/or transfer custom driving profiles from one autonomous vehicle to another autonomous vehicle without the need to recreate the driving profile. In this way, the driving profile of the user may be conveniently and efficiently utilized on one or more autonomous vehicles.
An embodiment of operating an autonomous vehicle is illustrated by an exemplary method 100 of
In an example of providing the driving preference, the driving profile may be selected, such as manually by the user and/or automatically by the automated driving component (e.g., the automated driving component may access a calendar of the user to identify an event time and location, and select the driving profile that will enable the user to arrive to the event on time or in a manner desired by the user for traveling to such an event). The driving profile may comprise a cautious profile, a shortest duration profile, a shortest distance profile, a leisurely profile, a driving enthusiast profile, a fuel economy profile, a scenic profile, a sightseeing profile, a weather profile, etc.
In an example, the driving profile may be evaluated to identify the driving preference. The driving preference may comprise a route preference (e.g., a scenic route preference, a shortest route preference), a speed preference (e.g., a speed equal to a speed limit, a speed 5 mph under the speed limit, a speed that is 10% under the speed limit, a speed equal to other cars traveling a route, a speed within a speed range, etc.), a lane preference (e.g., a right lane preference, a left lane preference, a carpool lane preference, an express pay lane preference, etc.), a tailgating preference (e.g., the user may prefer to maintain a minimum tailgating distance based upon the speed being traveled and/or a set tailgating distance, such as four car lengths regardless of speed, etc.), a turn preference (e.g., the user may prefer to avoid left hand turns, right hand turns at red lights, etc.), a traffic level preference (e.g., a traffic avoidance preference), a traffic control device preference (e.g., the user may prefer to avoid red lights, stop signs, etc.; the user may prefer to stop at yellow lights; etc.), a performance preference (e.g., a fuel performance preference), etc.
By way of example, the route preference may comprise a high speed route preference (e.g., the user may indicate a preference for routes with speed limits above 55 mph), a low speed route preference (e.g., the user may indicate a preference for routes on surface roads with speed limits below 40 mph), an atheistic route preference (e.g., the user may indicate a preference for routes through parks, nature preserves, etc.), a safe route preference (e.g., the user may indicate a preference for routes that avoid roads, intersection, and/or areas with a historically high occurrence of accidents, etc.), a shortest distance route preference (e.g., the user may indicate a preference for a route with the shortest distance), a traffic flow route preference (e.g., the user may indicate a preference for routes that avoid historically high traffic areas, current traffic jams, stop lights, roundabouts, construction zones, etc.), a route terrain preference (e.g., the user may indicate a preference for routes along flat roads; the user may indicate a preference for routes which avoid hilly regions; the user may indicate a preference to avoid routes where pot holes have been reported by other users; etc.), a traffic enforcement route preference (e.g., the user may indicate a preference for routes that avoid red light cameras or area's highly patrolled by law enforcement officers; the user may indicate a preference for routes that include speed cameras to reduce the likelihood that other drivers will be speeding; etc.). In another example, the performance preference may comprise a fuel performance preference (e.g., the user may indicate a preference to operate the autonomous vehicle to maximize fuel performance, such as by firing less cylinders when traveling a long distances on a highway, etc.), an environmental performance preference (e.g., the user may indicate a preference to operate the vehicle such that CO2 emissions are reduced, etc.), a sports performance preference (e.g., the user may indicate a preference to operate the vehicle such that handling, acceleration, and/or torque are maximized), etc.
In an example, the driving profile and/or the driving preference may be provided from a remote preference provider to the automated driving component. The remote preference provider may be hosted on a cloud-based server, a mobile device of the user (e.g., a smartphone, a tablet, a smart watch, etc.), and/or an in-vehicle human machine interface. In an example of providing the driving profile, a communication connection (e.g., a Wi-Fi connection, a Bluetooth connection, a cellular connection, etc.) may be created to provide the driving profile from the remote preference provider to the automated driving component. In this way, the driving profile may be conveniently and efficiently utilized by one or more autonomous vehicles (e.g., the driving profile may be provided to a personal autonomous vehicle of the user, a work autonomous vehicle of the user, and/or a family member's autonomous vehicle that the user is borrowing).
In an example of providing the driving profile, a calendar, an email client, a webpage, a social media profile, and/or a mobile application of the user may be assessed to identify event information for an event. The event information may comprise an event location, an event time, an event type (e.g., a work meeting, birthday party, doctor appointment, flight departure, etc.), and/or an event priority. The event information may be evaluated to select the driving profile based upon at least one of the event location, the event time, the event type, and/or the event priority. For example, responsive to determining that a business event having a high priority begins in 12 minutes, a driving profile may be selected that will enable the user to arrive at the event on time based upon the location of the event.
At 106, an operational parameter for the autonomous vehicle may be generated based upon the driving preference. The operational parameter may be utilized by the automated driving component to determine a manner in which the autonomous vehicle should perform under various conditions and/or in response to various events. The operational parameter may be configured based upon a characteristic of the autonomous vehicle (e.g., vehicle length, width, weight, braking ability, acceleration, turning radius, fuel range, etc.). In an example, the operational parameter may be utilized to determine a response for the autonomous vehicle as a result to a change in a driving condition (e.g., determine an amount of braking necessary to maintain a tailgating distance in response to a change in speed of a second vehicle traveling in front of the autonomous vehicle, determine a speed adjustment to safely operate the autonomous vehicle in response to a change in weather, determine a speed adjustment in response to a change in speed limit along a route, etc.).
In an example, a set of operational parameters may be generated based upon a set of driving preferences within the driving profile. A priority value may be determined for individual operational parameters within the set of operational parameters (e.g., operational parameters are assigned a priority value based upon the importance of the operational parameters to the user). The operational parameters within the set of operational parameters may be ranked to generate a ranked set of operational parameters. In an example, the operational parameters may be ranked based upon their priority value. The autonomous vehicle may be operated based upon the ranked set of operational parameters. For example, responsive to a maximum speed limit operational parameter being ranked higher than a right lane operational parameter, the automated driving component may direct the autonomous vehicle into the left lane as a result of a second vehicle traveling in the right lane at a speed under the speed limit.
At 108, the autonomous vehicle may be operated based upon the operational parameter. In an example, a route to a destination may be generated based upon the driving preference for the user and/or the operational parameter of the autonomous vehicle. Responsive to generating the route to the destination, the autonomous vehicle may be operated to travel the route based upon the operational parameters for the user. In an example, the operational parameter may be utilized to operate the autonomous vehicle in accordance with the driving preference (e.g., if the user prefers the autonomous vehicle be operated at speeds below the speed limit, the operational parameter may be utilized by the automated diving component to adjusted the speed of the autonomous vehicle as it travels across roads having various speed limits).
In an example, a condition of the user traveling within the autonomous vehicle may be determined (e.g., the user may be in a high stress state as a result of being stuck in traffic). The condition of the user may be determined by evaluating biometric data corresponding to the condition of the user. In an example, one or more biometric sensors may be utilized to obtain biometric data for the user (e.g., a smart watch worn by the user may collect heartrate data of the user, a conductive sensor in a surface of steering wheel may collect skin conductance data related to a perspiration level of the user, etc.). The biometric data may comprise heartrate data, body temperature data, skin conductance data (e.g., galvanic skin response data, electrodermal response data, psychogalvanic reflex data, skin conductance response data, etc.), voice stress analysis data, brainwave data (e.g., electroencephalography data), blood alcohol content data, etc. In another example, the user may provide the condition to the automated driving component though an interaction with a user interface (e.g., an interface displayed by a mobile device, a webpage, an in-vehicle human machine interface, a voice input or instruction, etc.).
In an example, the operation of the autonomous vehicle may be adjusted based upon the condition of the user. For example, responsive to the condition of the user not corresponding to a conditional state associated with the driving preference of the user, the operational parameter for the autonomous vehicle may be adjusted (e.g., if the user selected a low speed preference associated with a low stress state and the condition of the user is indicative of a high stress state, the operating speed of the autonomous vehicle may be adjusted to a lower speed). In another example, responsive to the condition of the user not corresponding to the driving preference, an adjusted route to the destination may be generated (e.g., if the user selected a high speed preference associated with a medium stress level and the user is experiencing a high stress state as a result of being stuck in traffic, the automated driving component may generate an adjusted route allowing for a faster rate of travel). The autonomous vehicle may be operated by the automated driving component to travel along the adjusted route to the destination based upon the operational parameter.
In an example, the user may be identified as entering a second autonomous vehicle. The driving preference (or driving profile) for the user may be provided to a second automated driving component of the second autonomous vehicle in response to the user entering the second autonomous vehicle (e.g., the driving profile of the user may travel with the user from autonomous vehicle to autonomous vehicle). For example, if the user rents an autonomous vehicle in another city, the driving profile for the user may be downloaded to the rented autonomous vehicle. In an example, the driving preference may be provided from the remote preference provider. A second operational parameter for the second autonomous vehicle may be generated based upon the driving preference and/or a second characteristic of the second autonomous vehicle. The second autonomous vehicle may be operated by the second automated driving component based upon the second operational parameter.
In an example, the user may provide feedback to the automated driving component. The feedback may provide an indication of whether the autonomous vehicle is operated as the user intended based upon the driving profile selected. The feedback may be utilized by the automated driving component to modify the operational parameters corresponding to the feedback. In an example, the feedback may be provided to the automated driving component in real time. The feedback may comprise an activity record of adjustments suggested and/or made to the operation of the autonomous vehicle by the user (e.g., responsive to a cautious driving profile being selected and the user reducing the speed of the autonomous vehicle, feedback may be provided indicating that the speed of the autonomous vehicle was greater than desired by the user). In another example, the feedback may be provided as a set of operational features. The set of operational features may be extracted from vehicle data collected while the automated driving component operated the autonomous vehicle along the route. In an example of extracting an operational feature, fuel consumption data collected at various speeds along the route may be indicative of an optimal speed for operating the autonomous vehicle along the route and/or a similar route (e.g., fuel usage data illustrating a fuel usage rate of 21 mpg at 65 mph and a fuel usage rate of 24 mpg at 55 mph may be indicative that it is more fuel efficient to operate the autonomous vehicle at 55 mph rather than at 65 mph). In another example of extracting an operational feature, heart rate data of the user collected at various points along the route may be indicative of an optimal tailgating distance for the user (e.g., heartrate data illustrating the user's heartrate was 60 bpm when the tailgating distance was 35 feet and 120 bpm when the tailgating distance was 10 feet, which may be indicative that the user prefers the 35 foot tailgating distance). In an example, the feedback from the user may be utilized to train an operational parameter model of the automated driving component. At 110, the method ends.
In an example, responsive to the scenic profile 224 being selected, the automated driving component 230 may receive the scenic profile 224 from the remote preference provider component 202. The scenic profile 224 may be evaluated by the automated driving component 230 to identify the aesthetic route preference 226 from the scenic profile 224. An operational parameter, such as an aesthetic route operational parameter 232 may be generated by the automated driving component 230 based upon the aesthetic route preference 226. The automated driving component 230 may be configured to operate the autonomous vehicle based upon the aesthetic route operational parameter 232. For example, the automated driving component 230 may configure the autonomous vehicle to travel along a longer route through a park rather than a shorter route through an industrial area based upon the aesthetic route operational parameter 232. In another example, the user may select a plurality of driving preferences and/or generate a plurality of operational parameters to control various aspect of the autonomous vehicle. In this way, the user may have more control over the operation of autonomous vehicles and thus a driving experience may be improved.
