Braking system has pressure sensor on pump output to detect pressure pulsations during pump operation that are evaluated to obtain measurement signal for controlling/monitoring pump

摘要

The system has valves (161-164) via which hydraulic fluid passes in regulated manner from a pressure reservoir (185) into each wheel brake cylinder, whereby the hydraulic fluid is pumped (190) into the pressure reservoir. A pressure sensor (200) on the output side of the pump determines pressure pulsations during operation of the pump that are evaluated (300) to obtain a measurement signal for controlling and/or monitoring the pump. An Independent claim is also included for a method of controlling and/or monitoring a pump in a braking system.
