Abstract:
A pedal assembly adapted to be mounted on a body structure of a motor vehicle and operative to generate a control signal for vehicle system, said assembly comprising:a support adapted to be mounted to the body structure; a pedal arm having an upper end pivotally mounted to said support for movement relative to the body structure and a lower end for supporting a pedal pad, said pedal arm being movable between a plurality of operational positions as a force is applied to said pedal pad; a magnet including multiple poles and cylindrical in shape with each of said poles having a predetermined width with said poles alternating between positive and negative orientations about the circumference of said magnet and a non-contact sensor mounted adjacent to said magnet such that said sensor remains fixed relative to said pedal arm at all operational positions wherein said sensor generates an electric control signal for controlling a vehicle system as said pedal arm is moved between said operational positions, said signal varying in magnitude by the extent of angular rotation of said magnet relative to said sensor, a non-rotatable pivot shaft fixed to said support and defining an axis of rotation for said pedal arm to pivot between operational positions, a transversely extending shaft for supporting said magnet and rotatably supported on said pivot shaft, said transversely extending shaft being concentric by being disposed about said pivot shaft, whereby said transversely extending shaft rotates about said pivot shaft about said axis of rotation as said pedal arm is moved between operational positions.
