Actuation responsive brake pedal pad assembly

摘要

A pressure sensitive pad assembly for a brake pedal having in one embodiment a pair of plastic films with metallized surfaces spaced apart by apertured spaces and embedded in an elastomeric pad to be placed on a brake pedal. Application of a brake actuating force on the pad causes the elastomer to deform closing contact between the metallized surfaces for actuating a brake light. In another embodiment a pressure sensitive transducer pad assembly has embedded in elastomeric material, a plurality of piezoelectric strips which are deformed, upon application of a brake actuating force to the pad, for providing an electrical signal indicative of the magnitude of the brake actuating force. In another embodiment an elastomeric pad spans a shallow recess in a support with piezoelectric material provided on the spanning surface and deformation of the pad into the recess deforms the piezoelectric material to provide a brake actuating force signal.
