Abstract
A brake-pressure control device is provided for a road vehicle with electrohydraulic multi-circuit brake system. For each wheel brake, a hydraulic servo-cylinder is driven by an electric motor. The servo-cylinders enables certain functions to be implemented, namely spot braking mode, including electronic control of the VA/HA braking force distribution (EBKV); anti-lock braking control (ABS function); traction control (TCS function); and vehicle movement control as a result of automatically controlled increase in brake slip at one or more of the wheels of the vehicle. A desired-value setting unit with a single-circuit master cylinder is provided which, in normal electronically controlled braking mode, serves as a desired-value transmitter and, in the event of failure of the vehicle's electronic system, can be activated as an emergency braking unit for building up brake pressure in the front-wheel brakes.
