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.

A method for determining the overall-deceleration values is attainable by actuation of wheel brakes, of a utility vehicle or of a vehicle combination with several axles. For the purpose of implementing a deceleration request in the course of partial brake applications, a braking-force distribution with braking forces distributed unequally to brake units with the wheel brakes of one or more axles is undertaken. In each instance one of the brake units is selected and a larger braking force is imposed via this selected brake unit than via the other brake units. A current deceleration of the utility vehicle or of the vehicle combination is measured or ascertained and is assigned as partial-deceleration value to the respectively selected brake unit and stored and the attainable overall-deceleration values are determined as the sum of the partial-deceleration values of all the brake units.

The invention relates to a method for operating a control device for a braking system of a motor vehicle, wherein the control device receives a braking request from a driver assistance system and determines a target value of a braking operation parameter of the braking system and determines an ideal temporal process for the braking operation parameter, which gradually leads to the target value, complying with a predetermined jerk criterion, and a determines a control fault of an actual value of the braking operation parameter in relation to the ideal process and determines a request value for a controller of a brake pressure pump of the braking system from the control fault on the basis of a controller unit. According to the invention, the control device determines a maximum achievable temporal gradient of the braking operation parameter by means of the brake pressure pump and examines whether the gradient fulfills a freezing criterion and, in the case of the freezing criterion being fulfilled, limits at least one control operation parameter of the controller unit and/or a gradient of the brake request.
