Überwachungseinrichtung für Fahrzeugbremssysteme mit einem Bremskraftverstärker

摘要

The invention concerns a monitoring device for vehicle brake systems that has a brake booster externally controlled by an electromagnetic valve. To construct said monitoring device with little hardware requirements and few computing operations, the invention proposes the installation of a comparator (20), which issues control commands depending on data pist provided by a pressure sensor and by reference pressures pr. Said device has at least one control unit (10) that issues control commands depending on the travel of the electromagnetic valve, wheel speed, reference speed, etc. It also has at least one logical AND gate (70) for the control commands of the microprocessor (1), the comparator (20) and the control unit (10).
