Lubricant film detection on brake discs or friction coefficient monitoring involves evaluating braking effect variation time and/or current ratio of braking effect to braking pressure

摘要

The method involves evaluating the variation of the braking effect with time and/or evaluating the current ratio of the braking effect achieved in relation to the braking pressure with respect to an increasing ratio. An increasing ratio is used as a signal representing the system response taking into account a known tolerated hysteresis.
