US Patent 7011186 Method for determining a brake state

In a method for determining the state of a motor vehicle brake, particularly the brake-lining state or the brake-lining thickness, a temperature sensor is arranged in the brake lining of the motor vehicle brake, and the temperature detected by the sensor is used to determine the brake state. In addition to a first temperature value, at least one second temperature value detected after the first temperature value and the time duration between the detection time points of the two temperature values are employed. The brake state is determined based on an evaluation of a time profile of temperature values sensed by said sensor.
