Method and apparatus for determining workload of motor vehicle driver

摘要

A steering angle sensor monitors the steering angle of a vehicle as the vehicle is driven. The steering angle signal is input to a processing device which generates steering angle prediction errors based on the received steering angle. The processing device then generates a distribution of steering angle prediction errors. The distribution of prediction errors is compared to the distribution of steering angle prediction errors representing load-free driving. The comparison represents the driver's workload.
