A cleaning device for a vehicle, with which at least one cleaning location is cleaned with pressurized cleaning liquid and/or pressurized ambient air, is proposed, including: a pump-compressor stage for sucking up and conveying the cleaning liquid and/or the ambient air, a fluid path which fluidically connects the pump-compressor stage upstream to a cleaning liquid tank and to an environment of the cleaning device, and a fluid distribution apparatus downstream of the pump-compressor stage, which is fed with the cleaning liquid and/or the ambient air by the pump-compressor stage, the fluid distribution apparatus being fluidically connected to the cleaning location. A vehicle with such a cleaning device, the first and the second use, and a cleaning method for a vehicle are also proposed.

Cleaning device

An actuator for a side door of a motor vehicle is described, which brings about automatic opening or closing of the side door depending on a signal and has a device for holding the side door in any open position. The holding device is realized by a function of the electric motor itself, according to which function the control device initiates a short-circuit function of the motor phases when the motor is activated, which causes a high current flow and thus a high torque for holding the side door open. By short-circuiting the motor phases, no additional components are required, since this is a special activation function of the motor.
