摘要: A method for providing an estimate of brake pad thickness. The method employs fusion of sensors, if used, and driver brake modeling to predict the vehicle brake pad life. An algorithm is employed that uses various inputs, such as brake pad friction material properties, brake pad cooling rate, brake temperature, vehicle mass, road grade, weight distribution, brake pressure, brake energy, braking power, etc. to provide the estimation. The method calculates brake work using total work minus losses, such as aerodynamic drag resistance, engine braking and/or braking power as braking torque times velocity divided by rolling resistance to determine the brake rotor and lining temperature. The method then uses the brake temperature to determine the brake pad wear, where the wear is accumulated for each braking event. A brake pad sensor can be included to provide one or more indications of brake pad thickness from which the estimation can be revised.

摘要: A wheel assembly for a non-driven wheel includes a rotating wheel hub with a shaft portion supporting a bearing inner race. A magnetic encoder is mounted for rotation with the shaft portion. A non-rotating component radially surrounds the shaft portion and has a bearing outer race. A cap is secured to the non-rotating component and covers the outer and inner races, the shaft portion and the magnetic encoder inboard of the races to seal an inboard side of the outer and inner races. A sensor is mounted to a non-rotating vehicle steering member externally to, not covered by, and not extending through the cap. The sensor is configured to deflect to be biased into continuous contact with an outer surface of the cap to read the magnetic encoder through the cap without extending through the cap.
