Brake Pad Prognosis System

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.

Radio frequency magnetron sputtering method to prepare superhard TiB2/TiAIN nano multilayer film

The invention relates to a radio frequency magnetron sputtering method to prepare superhard TiB2 / TiAIN nano-multilayers. By adopting the radio frequency magnetron sputtering technology, a radio-frequency power supply is used to excite plasma to sputter TiB2 and TiAI ceramic targets. Multilayers of TiB2 and TiAIN are deposited on a one-side polished Si (100) substrate. A mechanical pump and a molecular pump are adopted to pump the air pressure in a vacuum chamber to 3.0X10<-4> Pa to 1.0X10<-4> Pa. When TiB2 is deposited, pure argon gas is sputtered. The flow of argon gas is controlled with a mass flow controller, and is kept to be 4sccm to 60sccm. When TiAIN is deposited, argon gas and nitrogen gas are sputtered; and the ratio of nitrogen gas to argon gas is changed from 1:1 to 1:50. During the complete deposition process, the total working air pressure is: 0.1 Pa to 0.8 Pa when TiB2 is deposited; 0.2 Pa to 1.0 Pa when TiAIN is deposited. The cycle of the multi-layers is 30 layers to 200 layers. The novel superhard TiB2 / TiAIN nano-multilayers have the overall characteristics of high hardness, low internal stress, high binding force of the layer base. The novel superhard TiB2 / TiAIN nano-multilayers have important application prospects in reinforced films on the surface of knife edges and moulds.
