Title:
【発明の名称】ロック防止用電子装置の機能を監視するための安全回路
Document Type and Number:
Japanese Patent JP3355485
Kind Code:
B2
Abstract:
A safety circuit (12) for the surveillance of the proper functioning of an electronic wheel lockup-protected motor vehicle brake system includes automatic control circuits (10, 38), automatically controlled magnet valves (4, 46), and pick-up transducers (3, 47) at the motor vehicle wheels (2, 48) to be monitored. An error message and/or a partial shut-off of a defective pair of circuits, relating to wheel lockup protection circuits relating to diagonally disposed wheels, occurs in this safety circuit when an upward jump or a downward jump is recognized in the measured velocity of the one wheel and, simultaneously, the speed of the diagonally, oppositely disposed wheel or of any other wheel is measured to be above a limiting value. It is thereby avoided that an undesired error message occurs already when a jump in velocity is recognized, for instance in case of a standing vehicle, in case of a starting of the motor, or in case of a beginning of rolling of the vehicle.
