A brake pedal actuation sensor includes an optical coupler. In a preferred embodiment: the optical sensor is carried by a housing; a shutter is provided to interrupt the optical coupling according to the distance between the housing and a bearing; the shutter is carried by the bearing; 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.
A force sensitive sensor for a vehicle brake pedal assembly including a brake pedal, comprising: an optical coupler carried in said vehicle brake pedal assembly, said optical coupler including first and second members and means defining an optical coupling between said members which varies proportional to a force applied to said brake pedal; wherein said optical coupler generates an optical coupler output signal responsive to said optical coupling so that said output signal is proportional to said force applied to said brake pedal.
