Vehicle driver performance based on contextual changes and driver response
First Claim
1. A system for determining driver performance, the system comprising:
- a set of sensors fixedly attached to a vehicle being operated by a driver;
a transmitter disposed at the vehicle to transmit, via a wireless communication channel, a first set of time-series data obtained by the set of sensors, wherein each data point included in the first set of time-series data is associated with a respective time stamp and a respective geospatial location; and
one or more remote computing devices communicatively connected to the wireless communication channel and including one or more processors, one or more memories, and a set of computer-executable instructions stored on the one or more memories and executable by the one or more processors to;
collect, via the wireless communication channel, the first set of time-series data obtained by the set of sensors of the vehicle;
collect a second set of time-series data representing attributes of an environment in which the vehicle is operating, wherein each data point included in the second set of time-series data associated with a respective time stamp and a respective geospatial location;
generate a set of response data indicative of responses of the driver to one or more changes of the attributes of the environment that occur while the driver is operating the vehicle by identifying changes in the first set of time-series data corresponding to respective changes in the second set of time-series data, the set of response data including data indicative of respective elapsed time intervals between changes in the first set of time-series data and respective changes in the second set of time-series data; and
generate, based on the set of response data corresponding, an indication of a level of performance of the driver to the one or more changes of the attributes of the environment.

Abstract
Systems and methods for determining the performance of a driver of a vehicle based on changes, over time, in the context and environment in which the vehicle operates, and any resultant driver behavior are disclosed. A set of driver response data is created from based on an analysis of time-series data indicative of the driver'"'"'s operation of the vehicle in conjunction with time-series data indicative of changes in the vehicle'"'"'s context/environment. The driver response data indicates the types and magnitudes of the driver'"'"'s responses to various changes in the vehicle'"'"'s operating context/environment and the driver'"'"'s time-to-respond for each of the responses. That is, the driver response data indicates how a driver compensated his or her behavior (if at all) in response to different changes in the vehicle'"'"'s context and/or environment. The driver response data may be compared to one or more thresholds to determine the driver'"'"'s performance.

10. A method for determining driver performance, the method comprising:
-
collecting, via a wireless communication channel having one end terminating at a vehicle being operated by a driver, and by a set of remote computing devices communicatively connected to the wireless communication channel, a first set of time-series data obtained by a set of sensors fixedly attached the vehicle, wherein each data point included in the first set of time-series data is associated with a respective time stamp and a respective geospatial location; mapping, by the set of remote computing devices, the first set of time-series data with a second set of time-series data to form a set of mapped time-series data based on at least one of time stamps or geospatial locations, the second set of time-series data indicative of contextual attributes of an environment in which the vehicle is operating, and each data point included in the second set of time-series data associated with a respective time stamp and a respective geospatial location; generating, by the set of remote computing devices and based on the set of mapped time-series data, a set of response data indicative of respective responses of the driver to one or more changes to one or more conditions of the environment that occur while the driver is operating the vehicle in the environment, the set of response data including data indicative of respective elapsed time intervals between respective occurrences of the one or more changes to the one or more conditions and the driver'"'"'s respective responses; generating, based on the set of response data corresponding to the driver, an indication of a level of performance of the driver to the one or more changes to the one or more conditions of the environment; and transmitting, to at least one of the vehicle being operated by the driver, a user interface, or another computing device, at least one of the indication of the level of performance of the driver or at least a portion of the set of response data corresponding to the driver. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
