ABSTRACT:
A vehicle deceleration warning apparatus for use in a vehicle having brake lights, a floorboard and an accelerator pedal, the system including a piezoelectric sensor element connected to one of the accelerator pedal or the floorboard for outputting a first signal when subjected to appropriate stress conditions, a contact element connected to the other of the accelerator pedal or the floorboard for contacting the piezoelectric sensor in a manner which is dependent upon the rate of release of the accelerator pedal and causing the sensor to output the first signal in response thereto, and a circuit element connected to the brake lights and to the piezoelectric sensor for analyzing the first signal produced by the piezoelectric sensor and for actuating the brake lights in response to the analysis when the first signal is above a predetermined threshold.
