    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 brake assembly includes a brake pad, a bracket supporting the brake pad and having a first portion, a second portion spaced apart from the first portion, and a linkage interconnecting the first and second portions. The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly.

    摘要: A light-weight and sound-damped brake rotor for a vehicle braking system includes a rotor hat and a rotor cheek supported by the rotor hat. The rotor hat includes an axially-protruding central hub and a flange that extends radially from and circumferentially around the central hub. The rotor cheek, which provides at least one braking surface, is formed from two or more separate and distinct pieces which are fixedly secured to the flange of the rotor hat. Located within the rotor cheek underneath the at least one braking surface is a vibration damping element. The brake rotor derives its vibration-deadening and sound-damping effects from the vibration damping element through the occurrence of relative frictional contacting movement.

    摘要: A method of brake noise suppression via brake system pressure modulation is disclosed that includes detecting a brake apply and modulating a brake system pressure to disrupt formation of a friction instability upon detection of the brake apply. The brake system pressure can be modulated at each brake apply detected, only when the brake apply detected is of a brake apply type that is indicative of brake noise, or when the system actually detects brake noise. Further, the system can determine whether a brake apply is associated with a noise-inducing friction instability; and modulate the brake system pressure to disrupt formation of the noise-inducting friction instability by hindering development of the limit cycle associated with the noise-inducing friction instability.
