Method for operating a vehicle brake system using brake temperature

A method that compensates for temperature-related effects in a vehicle brake system. According to one embodiment, the method determines the temperature of a brake pad, calculates a temperature-based modifier, and then uses the temperature-based modifier to adjust one or more brake command signals pr...

Summary:A method that compensates for temperature-related effects in a vehicle brake system. According to one embodiment, the method determines the temperature of a brake pad, calculates a temperature-based modifier, and then uses the temperature-based modifier to adjust one or more brake command signals provided to the vehicle brake system so that they are compensated for temperature-related changes in the coefficient of friction (μ) of the brake pad and rotor. The method may be used with brake-by-wire systems such as electrohydraulic braking (EHB) systems and electromechanical braking (EMB) systems.
