Abstract
Sensors on a vehicle are used to sense different data corresponding to a plurality of metrics, which are related to a performance of driver while operating the vehicle. Values are determined for the metrics that are thus collected. These values are added together and the resulting total is normalized to produce a driver performance value or performance ranking. The metrics that are collected can include, for example, idle time data, acceleration and deceleration data, times that a speed limit is exceeded, and other metrics of interest to an owner of the vehicle for evaluating driver performance. A weighting factor can be applied to any metric considered of greater importance. The driver performance value can be displayed in real-time to the driver to provide an immediate feedback of performance, or the collected metrics can be transmitted to a remote location for determination of driver performance rankings at a later time.
