A movable component of a motor vehicle, for example a tailgate can be moved between two end positions by a drive unit of a moving device. A release energy for the drive unit, which is to be used to release the component at the start of a movement from a starting position, is selected as a function of the starting position.

The invention relates to a method for operating a radio system of a motor vehicle. In one embodiment, the method comprises: specifying an area surrounding the motor vehicle, determining which digital radio stations within this area can be received error-free using a receiving device of the radio system, and displaying only those digital radio stations which can be received error-free within this area. The invention furthermore relates to a radio system for a motor vehicle and to a motor vehicle with a radio system.

An operator control element in a motor vehicle generates an activation signal as a function of the activation of the operating element, and a control unit receives the activation signal and measures a signal length of the activation signal, and signals the activation if the signal length becomes greater than a predetermined debounce time. Despite possible incorrect triggering of the activation signal owing to voltage fluctuations, the debounce time is to be short. The control unit determines for this purpose an operating parameter, and on the basis of the operating parameter it is detected that a supply voltage, made available at the control unit, satisfies a predetermined instability criterion, and when the instability criterion is satisfied the control unit delays the measurement of the signal length for a predetermined blocking time.

The invention relates to a collision protection device for a pivotable hatch of a motor vehicle, comprising at least one sensor for detecting an obstacle in the pivoting range of the hatch, and comprising a control unit, which is designed to output, in dependence on sensor signals of the at least one sensor, control commands for stopping an opening movement of the hatch, wherein the at least one sensor is an optical visibility sensor, which is designed for capturing an optical visibility in an environment of the sensors.

In a method of controlling different lighting functions in a vehicle, activation of another one of the lighting functions is dependent on an actual speed of the vehicle, when manually switching from a currently activated one of the lighting functions to the other one of the lighting functions. In particular, when a low beam is automatically activated and a predefined speed is exceeded, activation of a parking light is barred while the low beam remains activated.

A motor vehicle includes an internal combustion engine and a parking assistance system with a system controller. During the assisted performance of a parking maneuver, the system controller receives one or more pieces of information from other controllers or units, which is continuously stored in the system controller. When restarting the internal combustion engine that has previously stalled during the ongoing parking maneuver, information previously stored by the system controller is accessed and forms the basis of a continued parking maneuver during a defined time interval, after which the assistance is once again based on current information acquired from the controllers or units.

A method and a device for controlling movement of an outside rearview mirror of a vehicle from an unfolded position to a folded position includes determining whether an ignition of a vehicle is turned off, and determining whether an object has been detected in a rear detection range of the vehicle. The mirror is moved into the folded position, when the ignition is turned off, and when either no object has been detected in the detection range, or when an object has been detected in the detection range and a seat associated with the mirror is unoccupied and/or a door associated with the mirror is opened. The vehicle has a seat occupancy sensor and a door switch.

The inventive bearing arrangement for a device for activating a vehicle brake has a central threaded spindle (,) which is secured against torsion in a fixed housing (,) and which is arranged in such a way that it can be displaced up to a brake disk (,) of the vehicle and from thereon axially. The inventive arrangement is also provided with an inner ring (,) which concentrically surrounds the threaded spindle (,) together with roll bodies. Said inner ring (,) is coupled with a rotating rotor of an electromotor (,) at the front and is supported with the same in the housing (,) by an axial roller bearing and a radial roller bearing so that it can rotate. According to the invention, the axial roller bearing of the inner ring (,) is made up of a planetary gear with several roll bodies serving as planets. Said roll bodies are situated between the inner ring (,) and a bore wall (,) of the housing (,) which is axial to the inner ring (,). This reduces the friction losses of the axial roller bearing.
