Abstract

A driver attitude detection system for a vehicle includes a forward facing imaging sensor for capturing image data of a scene occurring forwardly of and in the direction of forward travel of an equipped vehicle. An image processor is operable to process image data captured by the forward facing imaging sensor. A control, responsive at least in part to image processing by the image processor of the captured image data, is operable to determine driver performance and generate a control output indicative of driver performance. The driver attitude detection system may include at least one monitoring device for monitoring a vehicle characteristic of the equipped vehicle, and the control may, responsive at least in part to the at least one monitoring device, be operable to determine driver performance and generate the control output.
