Abstract: A steering system arranged in a vehicle having a steering wheel, a steering system control unit and a steering assistance unit with an electric motor. The steering system is designed to assist, by the motor of the steering assistance unit, a predefined steering movement of a driver at the steering wheel for steering steerable wheels of the vehicle and to steer the steerable wheels in accordance with the predefined steering movement. In this context, the steering wheel is mechanically coupled to the steering assistance unit. The steering system is also designed to block a predefined steering movement at the steering wheel, and therefore to block steering of the steerable wheels by the steering assistance unit, in a predefined state of rest of the vehicle.

Abstract: The invention relates to a device for implementing an additional heating system for a motor vehicle, having a heating/air-conditioning unit of a motor vehicle, which has a compressor that is driven by an electric motor and is arranged in a compression-type refrigerating circuit. In order to achieve additional heating of the motor vehicle in a simple manner while nevertheless obtaining the possibility of heating the motor vehicle rapidly and reliably, the electric motor (17) and/or at least the power components (30) of engine electronics (29) controlling the electric motor (17) are arranged in such a way that the waste heat of the electric motor (17) and/or the power components (30) is dissipated by a refrigerant or a heating agent of the heating/air-conditioning unit (1), which releases the heat absorbed to the interior of the vehicle.
