Abstract
A brake pedal position circuit includes a brake pedal mechanism having a ferromagnetic portion, which is movably mounted in a motor vehicle. At least one permanent magnet for generating a magnetic field is provided, as well as at least one Hall effect device for generating output data states that are dictated by variations in the magnetic field. A housing for the permanent magnet and the Hall effect device is fixedly secured in the vehicle so as to provide a portion in proximate relation to the brake pedal ferromagnetic portion when the brake pedal is in an 'at rest' position. Movement of the brake pedal mechanism in the vehicle changes the magnetic field and causes a resulting change in the Hall effect device data state.
