Abstract: The present disclosure relates to a brake pedal displacement sensing apparatus. The brake pedal displacement sensing apparatus includes a magnet assembly including a magnet that moves with the same displacement as that of a pedal rod that is moved by operation of a brake pedal, and a sensing unit including a sensor element, which senses a change in a magnetic field of the magnet and generates an electrical signal corresponding to the displacement of the pedal rod, and a connector, which is electrically connected to an electronic control unit (ECU) circuit board included in a brake control ECU to transmit the electrical signal from the sensor element to the brake control ECU.

Abstract: A stroke sensing apparatus for a brake pedal includes a pedal rod moved by an operation of the brake pedal; a magnet part mounted on the pedal rod and moved together with the pedal rod; a sensor spaced apart from the magnet part; a printed circuit board (PCB) part on which the sensor is mounted; and a pole piece part mounted on the PCB, spaced apart from the magnet part, and transmitting a magnetic field change generated in the magnet part to the sensor.
