A control device for a first motorized pressure build-up device of a braking system of a vehicle. The control device is designed to output at least one first piece of information to an activation device of a second motorized pressure build-up device of the braking system by, under consideration of the respective first piece of information, a first motor activatable in such a way that a pressure prevailing in at least one partial volume of the braking system is varied in accordance with a pressure change signal, which is interpretable as the respective first piece of information for the activation device using a second pressure sensor unit of the second motorized pressure build-up device.

A method and device for a vehicle having wheels which are each assigned a sensor for generating wheel signals. The unit determines whether a wheel is affected by a failure of the corresponding wheel signal. The unit acquires wheel signals which are assigned to the wheels, and for a wheel affected by a wheel signal failure, the corresponding wheel signal is acquired in the form of a substitute signal. The unit calculates a target brake pressure for a wheel at which an increase in brake pressure is necessary. The increase in brake pressure takes place in accordance with the wheel signal which is obtained for the wheel and in accordance with the determination as to whether the wheel is affected by a wheel signal failure. The unit further determines a slip threshold for an anti-lock brake control operation applied to the wheel affected by the wheel signal failure.

A plug-type driver assistance device includes an external brake module and an auxiliary control module. The external brake module includes a hydraulic pump and a control valve group, the control valve group includes an inlet valve and an outlet valve, and the hydraulic pump is connected between the inlet valve and the outlet valve. The auxiliary control module includes a receiving unit, a processing unit and an output unit. The processing unit selectively switches to the original vehicle control mode or the assist driving mode. The original vehicle control mode means that the processing unit receives the accelerator pedal signal and controls the output unit to output the accelerator pedal signal. The assist driving mode means that the processing unit receives the surrounding information of the vehicle, and generates an analog pedal signal and an analog braking signal.
