Driver Performance Metric
First Claim
1. A method, using a computer, for assessing driver performance relative to a standard of performance, the method comprising:
- receiving measurement data at a computer, the measurement data indicative of one or more vehicle state parameters corresponding to a driver operating the vehicle during a driving trip;
receiving reference data at the computer, the reference data indicative of one or more vehicle state parameters corresponding to a standard of performance for the vehicle during at least a portion of the driving trip; and
determining, at the computer, at least one metric of comparison based at least in part on the received measurement data and the received reference data, the metric of comparison indicative of an assessment of the driver operating the vehicle relative to the standard of performance for at least a portion of the driving trip.

Abstract
Systems and methods for quantifiable assessment of vehicle driver performance based upon objective standards are disclosed. The physical and/or control states of a vehicle are monitored by sensors during a driving trip. Measurement data, optionally comprising a measurement signal, is composed from parameters selected from the measured physical and/or control states. The measurement data is then compared to reference data, optionally comprising a reference signal, comprising the same or similar physical and control state parameters, for the same or analogous driving trip or portion thereof, including discrete driving tasks, as determined by one or more of: a known driver of specific attributes, a population average, or an autonomous driving algorithm. A metric of comparison may be determined as one or more characteristic metrics of a driving task, according to one or more path metrics of a driving task, or as a signal distance metric between the reference and measurement signals.

60. A computer program product embodied in a non-transitory medium and comprising computer-readable instructions that, when executed by a suitable computer, causes the computer to perform a method for assessing driver performance relative to a standard of performance, the method comprising;
-
receiving measurement data at a computer, the measurement data indicative of one or more vehicle state parameters corresponding to a driver operating the vehicle during a driving trip; receiving reference data at the computer, the reference data indicative one or more vehicle state parameters corresponding to a standard of performance for the vehicle during at least a portion of the driving trip; and determining, at the computer, a metric of comparison based at least in part on the received measurement signal and the received reference data, the metric of comparison indicative of an assessment of the driver operating the vehicle relative to the standard of performance.

61. A system for assessing driver performance relative to a standard of performance, the system comprising:
-
a measurement signal generator, the measurement signal generator being capable of generating a measurement signal that provides measured values for one or more parameters of a vehicle'"'"'s state while a driver is operating the vehicle on a driving trip; a reference signal generator, the reference signal generator being capable of generating a reference signal that, for at least a portion of the driving trip, provides values for one or more parameters of a vehicle'"'"'s state while it is being driving in accordance with a standard of performance; and a scorer, the scorer being capable of determining a metric of comparison between the reference signal and the measurement signal, the metric of comparison being indicative of how the driver executed the one or more driving tasks with the vehicle relative to the standard of performance, wherein the scorer is communicably connected to the reference signal generator and the measurement signal generator such that the scorer receives the reference signal and the measurement signal.
