Electronically pressure adjustable vehicle brake system and method for controlling an electronically pressure adjustable vehicle brake system

摘要

The invention relates to an electronically pressure adjustable vehicle brake system (10) and to a method for controlling an electronically pressure adjustable vehicle brake system (10). Such type of vehicle brake system (10) stabilizes the vehicle, assists in the operation of said vehicle brake system (10), and / or enables full automatic or semi-automatic traveling operation. Can. For this purpose, the vehicle brake system is a primary actuator system (14) for adjusting or regulating the various brake pressures at the wheel brakes (16), and also the vehicle brake system (10), in particular the primary actuator system (14). And an electronically controllable secondary actuator device (26) to protect against failure of the According to the present invention, when a malfunction occurs in the primary actuator device (14), the secondary actuator device (26) generates a dynamic axial pressure in the direction of the front axle (VA) generated at the time of brake operation. It is controlled to generate a brake pressure greater than the brake pressure that can be converted to the brake power from the wheel brakes (16.3, 16.4) of the rear axle (HA), taking into account the deviation. The provided device (40.2) comprises the brake pressure at the at least one wheel brake (16.3, 16.4) of the rear axle (HA) and the at least one wheel of the rear axle (HA). Reduce the wheel of the car associated with the brake (16.3, 16.4) to a value that does not lock. [Selected figure] Figure 1
