    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: An automotive product having a plurality of components coated with a refractory interface coating and method for making the same are provided. The automotive product may include at least a first component and a second component configured to interconnect and engage one another. The first component may be composed of a first high-density material. The second component may be formed of a second lower-density material. A refractory interface coating may be applied at the interconnection between the first and second components to provide an enhanced surface finish to limit friction, prevent metallurgical bonding between the first material and second material, provide a barrier against galvanic corrosion, and provide a thermal barrier between the first component and second component to guard against thermal deformation or change in dimension of the second component.

    摘要: One or more layers of vibration damping material are placed on one or more selected surface regions of a body portion of a vibratile metal article. The layer of damping material is covered with a thin metal sheet. The selected surface may be recessed in the body portion to receive the damping material. The covering sheet may be formed of the same metal composition as body portion, or of a compatible metal composition. The peripheral edges of the covering sheet are ultrasonically welded to the surface of the article body portion to confine the damping material against the selected surface(s) so that the damping material forms a vibration damping interface(s) with the surface(s) of the article. The damping material may function as a coulomb damping material, or a viscous damping material, or both.
