A controller is configured to control at least one valve of a brake system of a vehicle that is closed in a de-energized state. The controller includes an actuation device configured to actuate the valve into an open state and to keep the valve in the open state. A holding current with at least one first average target current strength is output as a control signal by the actuation device to the valve. The holding current output to the valve is increased to at least one second average target current strength which is greater than the first average target current strength while taking into consideration provided information pertaining to a current rotational speed of an electric motor of a piston/cylinder device of the brake system and/or at least one current hydraulic pressure in at least one sub-volume of the brake system.

A method for operating an electric motor for braking a vehicle, including controlling the electric motor in such a way that the vehicle is slowed or decelerated with the aid of a motor braking torque exerted by the controlled electric motor. The method includes ascertaining whether a requested setpoint speed change is in a predefined normal range, and if so, the electric motor is controlled in such a way that a load to be applied by the electric motor remains less than or equal to a nominal load capacity of the electric motor. If the requested setpoint speed change is outside the predefined normal range, the electric motor is controlled in such a way that the load to be applied by the electric motor exceeds the nominal load capacity of the electric motor, at least during a predefined overload operation time interval.

In a method and a device for predicting movement trajectories of a vehicle to prevent or reduce the consequences of an imminent collision, in which for predicting the movement trajectories, only those trajectories are considered for which, because of a combination of steering intervention and braking intervention, the forces occurring at the wheels of the vehicle are within the range corresponding to the maximum force transferable from the wheel to the road. Particularly for systems which provide an automatic braking and/or steering intervention for avoiding a collision or reducing the severity of a crash with another object, an automatic braking and/or steering intervention is carried out as a function of the pre-calculated movement trajectories.

In a method and a device for monitoring a brake system, e.g., a wheel pressure sensor suite of a brake system of a motor vehicle, the fault detection is implemented on the basis of a differential threshold being exceeded by a signal that is representative for the difference of the brake pressures at the individual wheel brakes of a wheel axle. In the process, the differential threshold is set as a function of the averaged rate of increase of the individual pressures at the wheel brakes. Fault detection is carried out on the basis of a model, which takes the instantaneous operating state of the brake system into account.
