Abstract: A main beam switching arrangement for a road vehicle has a lighting device switchable over main beam and dipped headlamps. A sensor device determines at least one ambient parameter, and a control unit with an activatable and deactivatable automatic function automatically switches over the lighting device as a function of the ambient parameter. An operator control unit generates switchover signals by an operator to manually bring about switching over the lighting device with priority. In each case, at least one change of state of the automatic function can be brought about by a first switchover signal for switching on continuous operation of the main beam that is not occurring at the time of signal generation. By way of a second switchover signal, continuous operation of the main beam, which is occurring at the time of signal generation, is switched off.

Abstract: A cascaded overall actuating system for a vehicle motion simulator is divided into an actuating system for small, high-frequency movements and an actuating system for large, low-frequency movements. A manipulator for implementing the low-frequency excitations is itself composed as a cascaded system of a rotary plate, a six-axle movement unit and a horizontal displacement device. To simulate movements which are as low in frequency as possible, the horizontal displacement device spans, as the actuator stage which is arranged at the lowest point in the cascade, a large movement area of 40 m×40 m. The six-axle movement unit with rotary plate and high-frequency actuating system is mounted on a carrier carriage which is supported in a freely displaceable fashion on a planar base surface bounded by the displacement paths of the horizontal displacement device and is pulled and/or pushed with respect to this base surface by means of the horizontal displacement device.

Abstract: A motor vehicle has an outer contour around which the headwind flows when driving has associated with it flow-influencing structure to reduce the air resistance of the motor vehicle is known. The flow-influencing structure are movably mounted in a vicinity of the outer contour and can be activated periodically with the aid of drive devices in order to introduce suitably time-dependent disturbances into the flow of the headwind in the vicinity of the flow-influencing structure.
