Abstract
A system for sensing the manner of operation of an automotive vehicle and for generating feedback signals to the vehicle operator as a function of the manner of operation includes a pressure sensor connected to the brake pedal so as to generate a multi-state output signal as a function of the instantaneous pressure applied to the brake, and a plurality of acceleration sensors supported so as to sense the rate of change of the motion about different axes. The sensor output signals are all provided to a controller which compares their outputs to values stored in a table to generate one of a stored set of output values. An audio signal generator receives the output values and generates an audio feedback signal to the vehicle operator as a function of the status of the sensors. The system may also provide a signal to the vehicle engine to prevent operation of the vehicle when excessively erratic operation is detected.
