FORCE SENSITIVE SIGNAL DEVICE FOR VEHICLE BRAKE PEDAL

摘要

A brake pedal actuation sensor includes an optical coupler (47,48). In a preferred embodiment: the optical sensor (47,48) is carried by a housing (40); a shutter (55) is provided to interrupt the optical coupling according to the distance between the housing and a bearing (52); the shutter (55) is carried by the bearing (52); and the distance between the housing and the bearing is dependent upon the force applied to the brake. Additionally, a circuit responsive to an output of the optical coupler is provided for generating an electrical output signal indicating brake pedal actuation.
