Patent Application
20170032673
Drivers are surrounded by vehicles that are driven by other drivers having varying degrees of driving competence. For example, a user may drive a route through a neighborhood, along a highway, and through a downtown area while traveling to work. While driving along the route, the user may drive alongside drivers having a variety of driving skills and behaviors, such as a teenager learning to drive, a college student that may be aggressively speeding because the college student is late to class, a truck driver lacking sleep, etc. Because the user may lack information about the individual driver's skills and behaviors, the user may assume that all of the drivers are dangerous and thus the user may default into a defensive driving behavior. It may be advantageous to provide the user with information regarding driving behavior history of other drivers within the user's vicinity in order to improve awareness and/or mitigate accidents.
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 providing driving behavior information and/or driver alerts are provided herein. In an example of providing driving behavior information, a client device module (e.g., a smartphone, a vehicle head unit such as a navigation system, a vehicle computing device, a tablet, a smart device, a wearable device, etc.) may be configured to identify a driver of a vehicle (e.g., an owner of the smartphone that is driving the vehicle). The client device module may be configured to collect driving behavior information of the driver (e.g., a braking pattern, a vehicle location, a vehicle speed, vehicle acceleration/deceleration, a weather condition, a roadway condition, a current time, driving condition visibility, whether the driver appears to be tired, etc.). In an example, the client device module may be configured to receive driver specified information from the driver (e.g., a number of passengers in the vehicle, whether the driver is in driver training, whether a child or infant is onboard, etc.). The client device module may be configured to provide the driving behavior information and/or the driver specified information to a driver alert provider for distribution to one or more vehicles within a threshold distance of the vehicle (e.g., the information may be provided over a wireless communication connection to the driver alert provider).
In an example of providing driver alerts, a driver alert provider (e.g., hosted on a device that may be remote to a client device module, such as a route navigation server) may be configured to receive driving behavior information of a driver from a vehicle, such as from the client device module. The driver alert provider may be configured to maintain a driver profile for the driver based upon the driving behavior information and/or other information such as driver specified information. The driver alert provider may be configured to generate a driver alert (e.g., a driving behavior of the driver, a driver risk score for the driver, a notice that the driver has 3 passengers and an infant onboard, etc.) based upon the driver profile. The driver alert provider may be configured to provide the driver alert to a second driver of a second vehicle that is within a threshold distance of the vehicle (e.g., the driver alert may be provided over a wireless communication connection to a device of the second driver). In an example, vehicle location data, such as global positioning system (GPS) data of the first vehicle, may be compared to vehicle location data, such as GPS data, of the second vehicle to determine that the second vehicle is within the threshold distance.
A driver may take affirmative action, such as providing opt-in consent, to allow access to and/or use of driving behavior information and/or driver specified information, such as for the purpose of providing driver alerts to other drivers and/or maintaining a driver profile of the driver (e.g., where the driver responds to a prompt regarding the collection and/or use of such information).
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 broadcasting driver alerts are provided herein. A client device module, such as a smartphone or vehicle computer, may collect and transmit driving behavior information, associated with a driver of a vehicle, to a driver alert provider. For example, the client device module may access onboard vehicle telemetry and/or sensors (e.g., a brake sensor, a speed sensor, etc.) to obtain the driving behavior information that may be sent using a wireless communication module of the client device module to the driver alert provider (e.g., a remote server that communicates driver alerts to client devices over wireless communication connections). The driver alert provider may maintain a driver profile of the driver, and may generate a driver alert (e.g., a driver risk score of the driver) based upon the driver profile. The driver alert provider may provide the driver alert to drivers of vehicles within a vicinity of the vehicle. The driver alert may be actively provided to a user in a non-distracting manner, such as through an audio notification, a projection onto a window or dashboard of a vehicle (e.g., a projection component may be integrated into the windshield for projecting driver alert notifications onto the windshield), etc. In an example, a driver alert may be used to improve travel route planning because a travel route creation module may use driver profiles and/or driver alerts to plan a route for a user that avoids drivers that pose safety hazards to the user (e.g., drivers having high risk driver risk scores). In this way, drivers may become aware of driving behavior history of a driver, which may improve awareness and mitigate accidents.
An embodiment of providing driving behavior information of a driver is illustrated by an exemplary method 100 of
At 106, driving behavior information of driver Dan may be collected. In an example, a computing device of the family minivan may collect driving statistics data as the driving behavior information (e.g., a braking pattern, a vehicle speed, a vehicle acceleration, a vehicle deceleration, roadway conditions, etc.). In another example, the smartphone may identify a current time, weather conditions, driving condition visibility, and/or other information as the driving behavior information. In this way, driving behavior information, indicative of how the driver is driving (e.g., a safe driving behavior pattern, a risky driving behavior pattern, a slow driving behavior pattern, an erratic driving behavior pattern, a tailgating driving behavior pattern, etc.), may be collected.
In an example, driver specified information may be received from the driver Dan (e.g., driver Dan may provide a voice command, comprising the driver specified information, to the smartphone or the vehicle head unit). The driver specified information may comprise a number of passengers within the family minivan (e.g., driver Dan may be in a high occupancy vehicle lane requiring at least 3 passengers), proof of insurance and/or driver license information (e.g., driver Dan may have provided a snapshot image of an insurance card and/or driver license), information as to whether driver Dan is in driver training, an age of driver Dan, information as to whether a child or infant is onboard the family minivan (e.g., so that other drivers may be warned to be more cautious), a driving skill of driver Dan (e.g., driver Dan may input a number of years driving; driver Dan may specify how skilled the driver feels the driver is at driving; etc.), information as to whether driver Dan is late (e.g., driver Dan may want to warn other vehicles that the driver will be more inclined to maneuver around slower traffic going below the speed limit), information as to whether driver Dan is driving under an emergency situation (e.g., driver Dan may be driving to a hospital), etc.
At 108, the driving behavior information and/or the driver specified information may be provided to a driver alert provider for distribution to one or more vehicles within a threshold distance of the family minivan. For example, a client device module (e.g., hosted by the smartphone, hosted by the vehicle head unit or computing device of the family minivan, etc.) may transmit the driving behavior information and/or the driver specified information over a wireless communication connection to a remote server hosting the driver alert provider. The driver alert provider may provide driver alerts, indicative of a driving behavior of driver Dan (e.g., a driver risk score, an description of the family minivan, a message such as whether driver Dan is driving under the emergency situation or has an infant onboard, etc.), to other users within a vicinity of the family minivan of driver Dan (e.g., a notification sent to head unit or navigation system of another vehicle; a notification sent to a smartphone of another driver such as a message provided through a driving app on the smartphone; etc.). In an example, the client device module of driver Dan within the family minivan may provide the driving behavior information and/or the driver specified information to a computing device of another driver within the vicinity of the family minivan of driver Dan (e.g., a driving app on the smartphone of driver Dan may send a message to the driving app on a smartphone of driver Tom that driver Dan has an infant onboard and is driving to the hospital).
In an example, the client device module of driver Dan may receive a driver alert from the driver alert provider. The drive alert may indicate a driving behavior of driver Tom that is driving a sports car within a threshold distance of the family minivan. The driver alert may indicate that driver Tom tends to driver 2 miles under the speed limit and poses a relatively low driving hazard risk to driver Dan. The driver alert, such as a driver risk score for driver Tom, may be provided to driver Dan, such as through the driving app on the smartphone or the vehicle head unit of the family minivan. At 110, the method 100 ends.
An embodiment of providing driver alerts of a driver is illustrated by an exemplary method 200 of
At 206, a driver profile may be maintained (e.g., maintained by the driver alert provider hosted on the route navigation server) based upon the driving behavior information and/or the driver specified information. The driver profile may comprise a file, a table, a database entry, or any other data structure used to store information regarding the driver and driving behavior of the driver. In an example, the driver profile may be populated with the driving behavior information, the driver specified information, a name of the driver, an address of the driver, a license plate number of the driver, a driver license number of the driver, insurance information of the driver, and/or personal identification information of the driver. In an example, the driver profile may be maintained with differing levels of access to portions of the driver profile. For example, a first level of access may be assigned to a first portion of the driver profile (e.g., an anonymous ID of the driver, a driver risk score, and/or other non-sensitive information such as a number of occupants in the vehicle) based upon a first privacy sensitivity of the first portion of the driver profile (e.g., information within the first portion may be provided to drivers within a threshold distance of the vehicle). A second level of access may be assigned to a second portion of the driver profile (e.g., driver license information, insurance information, recent violations, etc.) based upon a second privacy sensitivity of the second portion of the driver profile (e.g., information within the second portion may be provided to drivers, such as traffic safety authorities, that successful authenticate with the driver alert provider).
In an example, the driving behavior information may be evaluated to determine a driving behavior of the driver for inclusion within the driver profile. For example, a distribution of a particular aspect (e.g., an average speed above a speed limit, a frequency of not using a seat belt, a distance to a car that is in front of the driver, acceleration, deceleration, and/or other aspects) may be evaluated to determine whether the driver is riskier (e.g., more aggressive than average drivers). An aspect may be computed for a context, such as the frequency of acceleration and deceleration within a fixed time period, such as 15 minutes, during a congested traffic context. The information, such as the frequency of acceleration and deceleration, may be aggregated for a plurality of drivers to determine a distribution. If the driver is one or more standard deviations above an average of the distribution, then the driver may be labeled as a risky or aggressive driver, which may be included as the driving behavior within the driver profile.
At 208, a driver alert may be generated based upon the driver profile. For example, a driver risk score may be computed for inclusion within the driver alert by evaluating the driver profile using a statistical evaluation technique (e.g., a number of standard deviations from an average behavior of drivers). The statistical evaluation technique may increase or decrease the driver risk score based upon driver behavior patterns derived from the driver profile, such as increasing the driver risk score for rapid deceleration, rapid braking, excessive lane changing, driving over a speed limit, etc. and/or decreasing the driver risk score for driving within the speed limit, using turn signals, fully stopping at stop signs, etc. In an example, the driver alert may comprise identification information about the vehicle, such as a license plate number, a type of vehicle, a location of the vehicle relative to another vehicle to which the driver alert will be provided, etc.
At 210, the driver alert may be provided to a second driver of a second vehicle that is within a threshold distance of the vehicle. For example, the driver alert may be sent over a wireless communication connection to a smartphone (e.g., a driving app) and/or a vehicle head unit (e.g., a navigation unit) for display to the second driver as a textual (e.g., a message that the vehicle is driven by a high risk driver), audio (e.g., an audio message that the vehicle is driven by a high risk driver), and/or visual alert (e.g., display of a map populated with a vehicle indicator of the vehicle, which may be colored red to indicate high risk behavior of the driver). In an example, the driver alert may be provided based upon a court ordered instruction, the driver having a threshold number of driving violations, an insurance agency instruction (e.g., the driver may receive an insurance discount if the driver provides driver alerts to other users), the vehicle being located within a restricted access portion of a road (e.g., a number of occupants within the vehicle may be communicated to other drivers when the driver is in a high occupancy lane), and/or other information and instructions associated with the driver profile. In this way, the driver alert may be sent to one or more vehicles within the threshold distance of the vehicle.
In an example, a request, for driver information, may be received from a traffic safety authority (e.g., a police officer, a park ranger, etc.). The request may be evaluated to authenticate or not authenticate the traffic safety authority as being authorized to access the driver information (e.g., the request may be decrypted, a signature of the request may be verified, a login credential of the traffic safety authority may be evaluated, etc.). Responsive to authenticating the request (e.g., the traffic safety authority may have authorization to a high level of access to portions of the driver profile), driver information associated with one or more vehicles within a proximity threshold of the traffic safety authority may be obtained (e.g., first driver information of a first driver may be obtained from a first driver profile of the first driver; second driver information may be requested from a second driver; etc.). The driver information may be provided to the traffic safety authority. At 212, the method 200 ends.
The first client device module 304 may be configured to identify the first driver as driving the first vehicle 302. The first client device module 304 may collect driving behavior information 314 of the driver (e.g., a computing device of the first vehicle 302 may provide driving statistics such as speed, braking patterns, acceleration/deceleration patterns, turn signal usage, horn usage, turning patterns, lane changing patterns, etc. as the driving behavior information 314; the smartphone may provide driving patterns based upon global positioning system (GPS) data, weather information, time of day, etc. as the driving behavior information 314; etc.). For example, the first client device module 304 may determine that the first driver has a jerky braking pattern, an average of 5 mph speed over speed limits, normal acceleration, above normal deceleration, is driving in rainy weather conditions, and/or other information for inclusion within the driving behavior information 314.
The first device device module 304 may receive driver specified information 312 from the first driver (e.g., the user may provide the driver specified information 312 through a voice command to the smartphone). For example, the driver specified information 312 may indicate that the first driver did not provide proof of insurance, the first driver is a 25 year old male, the first driver is running late for an appointment, the first driver has no children onboard, the first vehicle has no other passengers, etc. The driver alert provider 316 may maintain a driver profile 318 for the first driver based upon the driving behavior information 314 and/or the driver specified information 312. The driver alert provider 316 may create and store a driver risk score 322, indicating that the first driver is a high risk driver having a score of 18 out of 20, within the driver profile 318. The driver alert provider 316 may assign a first level of access to a first portion 320 of the driver profile 318 (e.g., the first level of access may specify that a driver that is registered with the driver alert provider 316 may obtain access to the first portion 320), a second level of access to the driver risk score 322 (e.g., the second level of access may specify that a driver that is within a threshold distance of the first vehicle may obtain access to the driver risk score 322), and a third level of access to a third portion 324 of the driver profile 318 (e.g., the third level of access may specify that drivers that can successfully authenticate with the driver alert provider 316 may receive access to the third portion 324).
