Some embodiments of the present disclosure are directed to determining and validating a driver within a vehicle. More particularly, certain embodiments of the present disclosure provide methods and systems for determining which vehicle occupant is using a mobile device of the driver in view of positioning data of the mobile device within the vehicle. Merely by way of example, the present disclosure has been applied to verifying whether the vehicle occupant using the mobile device is the driver in order to accurately attribute driving behaviors to the driver. But it would be recognized that the present disclosure has much broader range of applicability.
A driver's driving behavior during a vehicle trip can be monitored for insurance related purposes. For example, various data generated by a mobile device of the driver are collected and analyzed to determine whether the driver was practicing safe driving. When the driver is accompanied by one or more passengers during the vehicle trip, a problem arises when a passenger uses or interacts with the driver's mobile device. Conventional systems would attribute the passenger's interactions to the driver and thus classify the driver as being distracted while driving. This misclassification can negatively impact the driver's insurance ratings. Accordingly, there exists a need to determine whether the driver or the passenger is using the mobile device during the vehicle trip so that data collected from the mobile device can be used to accurately assess the driver's driving behavior and not have any of the passenger's behavior imparted onto the driver.

Some embodiments of the present disclosure are directed to determining and validating a driver within a vehicle. More particularly, certain embodiments of the present disclosure provide methods and systems for determining which vehicle occupant is using a mobile device of the driver in view of positioning data of the mobile device within the vehicle. Merely by way of example, the present disclosure has been applied to verifying whether the vehicle occupant using the mobile device is the driver in order to accurately attribute driving behaviors to the driver. But it would be recognized that the present disclosure has much broader range of applicability.
At the process 110, the telematics data and the device interaction data generated by a mobile device during a vehicle trip are received according to certain embodiments. In various embodiments, the telematics data and/or the device interaction data are collected by one or more sensors (e.g., accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), cameras, gaze sensors, etc.) in the mobile device.
In certain embodiments, the vehicle trip is made by the driver of the vehicle. For example, the vehicle trip is made by the driver to commute to and from work. As an example, the vehicle trip is made by the driver in running errands (e.g., grocery shopping, visiting a hospital, picking up kids from school, etc.). For example, the vehicle trip is made by the driver for any suitable personal and/or business reasons (e.g., city travels, business trips, family vacations, etc.).
At the process 120, the telematics data and the device interaction data are analyzed to determine a plurality of driving instances in which the user interacts with the mobile device during the vehicle trip according to certain embodiments. In some embodiments, the plurality of driving instances in which the user interacts with the mobile device indicate usage of the mobile device during various driving events, such as high attention driving events (e.g., changing lanes, making turns, passing another vehicle, transiting through a roundabout, etc.) and/or low attention driving events (e.g., idling, cruising on an open highway, stopping, driving in light traffic, etc.).
In certain embodiments, the plurality of driving instances in which the user interacts with the mobile device are determined by correlating the telematics data and the device interaction data. For example, the telematics data may show that the vehicle is making lane changes while the device interaction data may show that the user is texting on the mobile device at the same time. As an example, correlation of the telematics data and the device interaction data will indicate that the user was interacting with the mobile device during a lane change maneuver. For example, the telematics data may show that the vehicle is completing a left turn while the device interaction data may show that the user is dialing a phone number on the mobile device at the same time. As an example, correlation of the telematics data and the device interaction data will indicate that the user was interacting with the mobile device during a left turn maneuver. For example, the telematics data may show that the vehicle is cruising on a straight road while the device interaction data may show that the user is responding to an email on the mobile device at the same time. As an example, correlation of the telematics data and the device interaction data will indicate that the user was interacting with the mobile device during steady vehicle travel. For example, the telematics data may show that the vehicle is moving at a slow speed while the device interaction data may show that the user is taking a picture with the mobile device at the same time. As an example, correlation of the telematics data and the device interaction data will indicate that the user was interacting with the mobile device during low-speed driving.
At the process 130, whether or not the user of the mobile device is the driver of the vehicle during the vehicle trip is determined based at least in part upon the plurality of driving instances by using the classification technique according to certain embodiments. In various embodiments, the classification technique determines whether the user is the driver by classifying each of the plurality of driving instances involving user interactions associated with the mobile device.
In some embodiments, the classification technique analyzes usage of the mobile device during high attention driving events. For example, the classification technique is implemented according to at least
At the process 140, the positioning data associated with the mobile device within the vehicle during the vehicle trip are received according to certain embodiments. In various embodiments, the positioning data indicate a location of the mobile device within the vehicle. In some embodiments, the positioning data are analyzed or processed to determine if the user of the mobile device is situated in a driver seat position of the vehicle during the vehicle trip. For example, processing of the positioning data is implemented according to at least
At the process 150, the classification technique is validated based at least in part upon the positioning data associated with the mobile device within the vehicle and whether or not the first user has been determined to be the driver of the vehicle according to certain embodiments. In various embodiments, the classification technique is validated in view of the positioning data to determine the accuracy of the classification technique.
In some embodiments, if the user of the mobile device is determined to be driver of the vehicle, validating the classification technique involves verifying that the user of the mobile device is in the driver seat position of the vehicle during the vehicle trip according to the positioning data. For example, if the positioning data show that the mobile device was in a driver seat of the vehicle during the vehicle trip, then user interactions of the mobile device can be attributed to the driver.
In certain embodiments, if the user of the mobile device is determined not to be driver of the vehicle, validating the classification technique involves verifying that the user of the mobile device is not in the driver seat position of the vehicle during the vehicle trip according to the positioning data. For example, if the positioning data show that the mobile device was in a rear seat of the vehicle during the vehicle trip, then it is impossible to attribute any user interactions of the mobile device to the driver.
At the process 210, the telematics data and the device interaction data are collected by the mobile device (e.g., first mobile device, second mobile device) during one or more vehicle trips according to certain embodiments. In some embodiments, the telematics data indicate driving maneuvers made during the one or more vehicle trips (e.g., braking, acceleration, cornering, stopping, etc.). In certain embodiments, the device interaction data indicate user interactions with the mobile device during the one or more vehicle trips (e.g., texting, making a phone call, interacting with an application on the mobile device, etc.). In various embodiments, the telematics data and/or the device interaction data are collected by one or more sensors in the mobile device.
At the process 220, the telematics data are analyzed to determine one or more first driving events of a predetermined type during the one or more vehicle trips according to certain embodiments. In various embodiments, the one or more first driving events of the predetermined type correspond to high attention driving events that require a high level of mental focus or alertness when operating the vehicle (e.g., entering/exiting a highway ramp). In some embodiments, in addition to the telematics data, vehicle environment data (e.g., location data, traffic data, weather data, etc.) collected or received by the mobile device are analyzed to determine the one or more first driving events.
At the process 230, one or more second driving events of the predetermined type during which the user interacts with the mobile device are determined according to certain embodiments. In various embodiments, the one or more second driving events indicate mobile device usage during the high attention driving events.
In some embodiments, the one or more second driving events of the predetermined type are determined by correlating the telematics data and the device interaction data. For example, the telematics data may show that the vehicle is traveling on a highway on-ramp while the device interaction data may show that the user is swiping on a screen of the mobile device at the same time. As an example, correlation of the telematics data and the device interaction data will indicate that the user was interacting with the mobile device while a highway entrance was taking place.
In certain embodiments, the one or more second driving events of the predetermined type are determined by correlating the telematics data, the device interaction data, and the vehicle environment data. For example, the telematics data and the vehicle environment data may show that the vehicle is traveling in a congested urban area while the device interaction data may show that the user is constantly viewing the mobile device at the same time. As an example, correlation of the telematics data, the device interaction data, and the vehicle environment data will indicate that the user was interacting with the mobile device while engaged in stop and go traffic.
At the process 240, a ratio of the number of the one or more second driving events to the number of the one or more first driving events is calculated according to certain embodiments. In various embodiments, the ratio compares the number of high attention driving events in which mobile device usage was detected to the total number of high attention driving events. At the process 250, whether or not the user of the mobile device is the driver of the vehicle during the one or more vehicle trips is determined by comparing the ratio to a predetermined threshold according to certain embodiments.
In some embodiments, if the ratio is less than the predetermined threshold, the user of the mobile device is determined to be the driver of the vehicle during the one or more vehicle trips. For example, the user of the mobile device is attributed to the driver of the vehicle because mobile device usage during the high attention driving events was relatively low when compared to the total number of high attention driving events.
In certain embodiments, if the ratio is greater than the predetermined threshold, the user of the mobile device is determined not to be the driver of the vehicle during the one or more vehicle trips. For example, the user of the mobile device is not attributed to the driver of the vehicle because mobile device usage during the high attention driving events was relatively high when compared to the total number of high attention driving events. As an example, the user of the mobile device can be attributed to another individual (e.g., a passenger) in the vehicle.
At the process 310, the telematics data and the device interaction data are collected by the mobile device during one or more vehicle trips according to some embodiments. In various embodiments, the telematics data and/or the device interaction data are collected by one or more sensors in the mobile device.
At the process 320, the device interaction data are analyzed to determine one or more first device interaction events during the one or more vehicle trips according to certain embodiments. In some embodiments, the one or more first device interaction events indicate user interactions with the mobile device during the one or more vehicle trips (e.g., turning the mobile device on/off, moving the mobile device, viewing the mobile device, etc.).
At the process 330, the telematics data are analyzed to determine one or more driving events of a predetermined type during the one or more vehicle trips according to certain embodiments. In various embodiments, the one or more driving events of the predetermined type correspond to low attention driving that require a low level of mental focus or alertness when operating the vehicle (e.g., driving with no traffic). In some embodiments, in addition to the telematics data, vehicle environment data (e.g., location data, traffic data, weather data, etc.) collected or received by the mobile device are analyzed to determine the one or more driving events.
At the process 340, one or more second device interaction events that occurred during the one or more driving events of the predetermined type are determined according to certain embodiments. In various embodiments, the one or more second device interaction events indicate mobile device usage during the low attention driving events.
In some embodiments, the one or more second device interaction events are determined by correlating the telematics data and the device interaction data. For example, the device interaction data may show that the user is typing into the mobile device while the telematics data may show that the vehicle is idling at the same time. As an example, correlation of the telematics data and the device interaction data will indicate that mobile device usage occurred while the vehicle was not in motion.
In certain embodiments, the one or more second device interaction events that occurred during the one or more driving events of the predetermined type are determined by correlating the telematics data, the device interaction data, and the vehicle environment data. For example, the device interaction data may show that the user is moving the mobile device from one location to another while the telematics data and the vehicle environment data may show that the vehicle is traveling in a rural area at the same time. As an example, correlation of the telematics data, the device interaction data, and the vehicle environment data will indicate that mobile device usage occurred while the vehicle was engaged in open road travel.
At the process 350, a ratio of the number of the one or more second device interaction events to the number of the one or more first device interaction events is calculated according to certain embodiments. In various embodiments, the ratio compares the number of mobile device usages that occurred during low attention driving events to the total number of low attention driving events. At the process 360, whether or not the user of the mobile device is the driver of the vehicle during the one or more vehicle trip segments is determined by comparing the ratio to a predetermined threshold according to certain embodiments.
In some embodiments, if the ratio is less than the predetermined threshold, the user of the mobile device is determined not to be the driver of the vehicle during the one or more vehicle trip segments. For example, the user of the mobile device is not attributed to the driver of the vehicle because mobile device usage during the low attention driving events was relatively low when compared to the total number of low attention driving events. As an example, the user of the mobile device will be attributed to another individual (e.g., a passenger) in the vehicle.
In certain embodiments, if the ratio is greater than the predetermined threshold, the user of the mobile device is determined to be the driver of the vehicle during the one or more vehicle trip segments. For example, the user of the mobile device is attributed to the driver of the vehicle because mobile device usage during the low attention driving events was relatively high when compared to the total number of low attention driving events. As an example, the driver can afford to interact with the mobile device because the chances of becoming distracted during the low attention driving events are small.
At the process 410, the first plurality of positioning measurements captured by a first mobile device within a vehicle during a vehicle trip are received according to certain embodiments. In various embodiments, the first mobile device corresponds to the mobile device of
At the process 420, the second plurality of positioning measurements captured by a second mobile device within the vehicle during the vehicle trip are received according to certain embodiments. In some embodiments, each of the second plurality of measurements includes a measured geographic location and an error estimate. In certain embodiments, the second plurality of positioning measurements are captured by one or more sensors (e.g., GPS sensors, accelerometers, gyroscopes, etc.) in the second mobile device.
At the process 430, the respective enhanced geographic location measurements for the first plurality of positioning measurements and the second plurality of positioning measurements are calculated according to certain embodiments. In some embodiments, the respective enhanced geographic location measurements are calculated based on the measured geographic location and the error estimate corresponding to each of the first plurality of positioning measurements and the second plurality of positioning measurements.
In certain embodiments, the respective enhanced geographic location measurements are calculated using a Kalman filter. For example, the Kalman filter determines an estimated geographic location measurement for a current geographic location measurement based on a previous geographic location measurement. As an example, the Kalman filter calculates the estimated geographic location measurement by integrating an acceleration value associated with the previous geographic location measurement over a period of time between measurements to determine a displacement estimate from the previous geographic location measurement. For example, the Kalman filter adds the displacement estimate to the previous geographic location measurement to determine the estimated geographic location measurement. As an example, the Kalman filter calculates an enhanced geographic location measurement by taking a weighted average of the current geographic location measurement and the estimated geographic location measurement. For example, the weights assigned to the current and the estimated geographic location measurements are based on a predicted error of the current and the estimated geographic location measurements where a lesser predicted error corresponds to a greater weight.
At the process 440, the predicted position of the first mobile device relative to the second mobile device with respect to a forward direction of travel of the vehicle based at least in part upon the respective enhanced geographic location measurements are determined according to certain embodiments. For example, the first mobile device and the second mobile device may be determined to have the same forward direction of travel with the relative positions of the first mobile device and the second mobile device being constant with respect to the forward direction of travel. As an example, the respective enhanced geographic location measurements may indicate that the first mobile device is on average to the left of the second mobile device with respect to the direction of forward movement of the vehicle.
In some embodiments, other sensor data (e.g., acceleration data measured by an accelerometer and/or gyroscope) can be used to determine the predicted position of the first mobile device relative to the second mobile device. For example, assume that the first mobile device is a left position (e.g., driver seat) and the second mobile device is in a right position (e.g., front passenger seat). As an example, if the vehicle makes a right turn, the first mobile device has a longer turning radius than the second mobile device. For example, the first mobile device will experience a greater angular acceleration than the second mobile device as a result of the right turn of the vehicle. As an example, the angular acceleration can be used to determine that the first mobile device is to the left of the second mobile device with respect to the direction of forward movement of the vehicle. For example, assume the first mobile device is in a front position and the second mobile device is in a rear position. As an example, if a degree of incline at which the vehicle is moving changes (e.g., vehicle begins to move up or down a hill), the first mobile device will experience a change in vertical acceleration before the second mobile device. For example, a delay in the vertical acceleration of the first mobile device and the second mobile device can be used to determine that the first mobile device is a certain distance in front of the second mobile device with respect to the direction of forward movement of the vehicle.
At the process 450, the driver of the vehicle is identified to be associated with the first mobile device based at least in part upon the predicted position of the first mobile device relative to the second mobile device according to certain embodiments. In various embodiments, a map is generated indicating the position of the first mobile device with respect to the second mobile device within the vehicle based on the predicted position of the first mobile device relative to the second mobile device. For example, the map is analyzed to determine that the first mobile device is situated in a driver seat position of the vehicle during the vehicle trip.

In some embodiments, the collected data are transmitted directly to the server 506 via the network 504. For example, the collected data are transmitted to the server 506 without being stored in the memory 518. In certain embodiments, the collected data are transmitted to the server 506 via a third party. For example, a data monitoring system stores any and all data collected by the one or more sensors 524 and transmits those data to the server 506 via the network 504 or a different network.

According to various embodiments, the server 506 receives, via the network 504, the data collected by the one or more sensors 524 using the communications unit 534 and stores the data in the data storage 536.

According to certain embodiments, any related information determined or generated by the method 100, the method 200, the method 300, and/or the method 400 (e.g., plurality of driving instances, first driving events, second driving events, first device interaction events, second device interaction events, enhanced geographic location measurements, etc.) are transmitted back to the client device 512, via the network 504, to be provided (e.g., displayed) to the user via the display unit 522.
