Abstract: The present disclosure relates to a vehicle, a method, a device and a steering system for a vehicle. In particular, the disclosure relates to a device for a vehicle with a first direct voltage source and at least one second direct voltage source, which are connected in series, for operating a consumer in the vehicle. The device comprises a potential tap which is designed to tap a potential between the first and the second direct voltage source. The device further comprises a circuit which is designed to provide the potential tapped between the first and the second direct voltage source for operating the consumer in the event of a fault in the first or second direct voltage source.

Abstract: A hydraulic servo-steering device includes a pump and a pump drive motor. At least one defined high power stage (C) and one defined low power stage (B) are provided in which the motor is selectively operated. Moreover, a defined additional power stage (A) is provided for the motor, in which the speed of the motor is reduced with respect to the low power stage (B). According to a method for controlling the pump drive motor of the hydraulic servo-steering device, the motor is operated in the additional power stage (A) under certain conditions which rule out an impairment to driving safety.
