Electrohydraulic Braking System Comprising Vehicle Dynamics Control

An electrohydraulic brake system with driving dynamics control comprising a master cylinder that is operable by a brake pedal and includes at least one piston, which is displaceably arranged in a housing of the master cylinder and delimits a hydraulic pressure chamber together with the housing, the pressure chamber being connectable to an unpressurized pressure fluid reservoir by way of a pressure fluid reservoir connection and a pressure fluid channel and to wheel brakes to by way of an outlet, with a pressure fluid supply device supplying pressure fluid from the pressure fluid reservoir in the direction of the wheel brakes in the case of driving dynamics control. In order to achieve a short reaction time of the driving dynamics control and, simultaneously, a short lost travel of the master cylinder, a bypass channel is interposed between the pressure fluid reservoir connection and the outlet of the master cylinder, and a valve is arranged in the bypass channel, which allows pressure fluid flow from the pressure fluid reservoir through the bypass channel to the pressure fluid supply device and prevents pressure fluid flow in the opposite direction.
