Reporters obtained the following quote from the background information supplied by the inventors: “Vehicles are typically operated by a human vehicle operator (e.g., a vehicle driver) who controls both steering and motive controls. Currently known methods for determining or rating a driver’s performance typically include collecting telematics data from the driver’s vehicle while a driver operates the vehicle, and analyzing the collected data to generate a rating or determination of the driver’s performance in operating the vehicle. Typical telematics data that is collected to rate a driver’s performance includes vehicle movement data such as speed, acceleration, cornering, braking, and the like. Other data that is conventionally used in rating a driver’s performance include the time of day, miles traveled, and whether (or not) and/or where the vehicle is garaged. Conventionally, a driver’s performance rating is reflected by an average over a period of time, such as a six-month or yearly average.”
In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors’ summary information for this patent: “The present disclosure generally relates to systems and methods for determining or rating driver safety performance based on relativity, e.g., to other drivers and/or to particular combinations of environmental conditions or contexts. Embodiments of example systems and methods are summarized below. The methods and systems summarized below may include additional, less, or alternate actions, including those discussed elsewhere herein.
“In an embodiment, a system for determining driver performance may comprise one or more communication interfaces; an access mechanism to a first set of data indicative of respective behavior of a plurality of drivers of a plurality of vehicles that traverse a plurality of routes, where the first set of data is based on data obtained by a set of sensors while the plurality of drivers operate respective vehicles along the plurality of routes; one or more processors; one or more non-transitory memories coupled to the one or more processors; and computer-executable instructions stored on the one or more non-transitory memories thereby particularly configuring the one or more non-transitory memories.
