Method for recovering information about wear condition of friction lining at disk brake or friction clutch in passenger car, involves determining value for delay during deceleration, and recovering wear condition depending on value

摘要

The method involves determining value for a delay during deceleration, and recovering a wear condition depending on the determined value. The value for the delay is extracted from a delay signal or computed from a rotational speed signal (n). A value for acceleration (a) is extracted from an acceleration signal or computed from the rotational speed signal. A pressure (D) exerted by a friction lining on a friction partner is considered during recovering the wear condition of the friction lining. An independent claim is also included for a friction brake or friction clutch.
