An emergency brake valve system for a pneumatic brake system of a vehicle, in particular of a rail vehicle, includes a first valve and a second valve, wherein the first valve is configured to conduct an auxiliary pressure to, or isolate this from, the second valve, whereas the second valve is configured to provide either a static or a regulated pressure in a manner which is dependent on the auxiliary pressure. The first valve is configured in such a way that it isolates the prevailing auxiliary pressure from the second valve in regular operation, with the result that the second valve provides a regulated pressure, and that it conducts the prevailing auxiliary pressure to the second valve in emergency operation, with the result that the second valve provides a static pressure.

A control device of a brake system, according to the present invention, includes, as redundancy, a first control unit for controlling the valve, the motor and the like of a brake system by receiving a sensor unit input, and a second control unit capable of performing the same function as the first control unit when the first control unit malfunctions, and thus the present invention can control the brake system of a vehicle by using the second control unit in an emergency situation in which the first control unit does not normally operate.

The invention relates to a method for decelerating a motor vehicle at least during emergency braking, in which method a first braking torque is applied to at least one front wheel of the motor vehicle by means of at least one service brake system of the motor vehicle. According to the invention, at least one parking brake different from the at least one service brake system is activated by a control apparatus of the motor vehicle and a second braking torque is thereby applied to the at least one front wheel while the first braking torque is applied. A further aspect of the invention relates to a motor vehicle.

According to at least one embodiment, the present disclosure provides an electrohydraulic brake system including main brake assemblies, electronic parking brakes (EPBs), a main control unit, and a redundancy control unit (RCU). The main brake assemblies generate a braking force in one or more front wheels and one or more rear wheels of a vehicle. The electronic parking brakes (EPBs) generate a braking force to one of the front wheels and rear wheels. The main control unit is configured to control the operation of the main brake assembly. The redundancy control unit (RCU) is configured to control the operation of the electronic parking brake. Here, the redundancy control unit performs, upon determining that a malfunction occurs in a braking function of the main control unit, a slip control on the vehicle by using the electronic parking brake based on signals from one or more wheel speed sensors.
