Compensating for wear and temp. differences at brake units of vehicle - using pressure control, position sensor to detect operation and electronic control unit picking up signals of sensors of brake units

摘要

When different brake unit position sensor signals are received at the electronic control unit (8), the higher signal causes a pressure change at the lower signal. During operation of the braking unit, a variable number of regulating cycles is carried out. These include: pressure control, signal determination and signal evaluation, resulting in pressure changes. During a first phase of the operation, a low number of regulating cycles are carried out to compensate for wear. In a second phase, a higher number of regulating cycles is undertaken to compensate for the pressure differences. ADVANTAGE - In one phase only small heating influence exists; in second phase, measures are taken to reduce unpermitted thermal loading. Brake lining wear is reduced and higher quality of temp. compensation results.
