摘要： A position sensing system and method for a braking assembly for a vehicle. The braking assembly includes a rotor (104, 1104), a caliper assembly (102, 1102) disposed around the rotor (104, 1104) and having a fixed mount bracket (106, 1106) and a floating portion (108, 1108) which moves when the brakes are applied. The position sensing system has a sensing element (226, 426) and a reference portion (560). The sensing element (226, 426) is attached to a location of the braking assembly such that the reference portion (560) moves in relation to the sensing element (226, 426) when the floating portion (108, 1108) moves. The sensor assembly is configured to generate a signal correlative to the relative positions of the sensing element and reference portion. The position sensing system includes a processor configured to store predetermined signatures and determine a condition of a component of the vehicle based on a match between the signal and one of the predetermined signatures.
