Operating hydraulically operated locking device for wheel brake involves measuring and evaluating hydraulic pressure profile of locking device when it is activated to check locking device function

摘要

The method involves measuring and evaluating the pressure profile (p) of the hydraulic pressure of the locking device when the locking device is activated and drawing a conclusion regarding the locking of the wheel brake by the locking device from the pressure profile. The pressure profile is checked for a step pressure change. An independent claim is also included for the following: (a) a wheel brake for a motor vehicle with a hydraulically operated locking device.
