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.

Method and device for automatically switching to main beam

In a method and apparatus for radio-based issuing of warnings of hazards to the driver of a vehicle having a data receiver, the data receiver receives data from at least one data transmitter of at least one other vehicle, and evaluates the received data. The received data comprising information about the position, speed and direction of travel of the transmitting vehicle. The approach speed between the receiving vehicle and transmitting vehicle are determined in order to evaluate the received data in the receiving vehicle. According to the invention, in order to evaluate the received data in the receiving vehicle, the distance between the transmitting vehicle and the receiving vehicle is determined, and it is determined whether information is output to the driver, based on the distance between the transmitting vehicle and receiving vehicle, and based on the approach speed between the transmitting vehicle and receiving vehicle.

Device and method for radio-based danger warning

In order to make warning devices more efficient, it is known to design parameters to be variable and therewith to be adaptable depending upon the state or condition of a user of the warning information. Herein, for example, warning start points are changed or multi-stage warnings are engineered depending upon urgency. The disadvantage of such an adaptive system can however reside therein, that the mechanistic detection of the condition of the operator using various sensor systems and the subsequent output to the operator or the operator assistant system is not always acceptable, which can irritate the vehicle operator or occupants. In order to increase the acceptance by the user of the warning information it is proposed that in the lead-up to a planned change in the mode and manner of the output of the warning information, communication is initiated with at least one of the users. In the framework of this communication a user can indicate his acceptance or declining with respect to the planned change.

Dialog system for warning and information systems

The invention relates to a hazard-prevention system for a vehicle. The vehicle has devices for sensing driving state variables, for sensing ambient data and for sensing the driver's activity, and a data processing device. The data processing device is provided for processing the sensed data and for actuating a safety device in accordance with a predefined control strategy. According to the invention, the vehicle has a device for identifying the driver, and the data processing device derives a driver load factor related specifically to the driver from the driving state variables, the ambient data and the data relating to the activity of the driver, and said driver load factor is used to adapt the control strategy.

The invention concerns a system for assisting an operator of a technical appliance, with a image display device (), of which the image is in the normal field of vision of the operator, for display of operationally relevant information in the form of images or symbols (). According to the invention, a respective image or symbol is displayed at least once for a brief period of time, of which the duration is below the threshold of conscious recognition and above the threshold of subconscious recognition of the operator.

In an information system for a vehicle having a plurality of information sources for outputting a respective associated information signals when an associated information-generation condition is met, two or more vehicle-control information sources of different types are coordinate with one another, without conflict, in terms of their information output in such a way that at any time at most one of these vehicle-control information items is output. As an alternative, or in addition vehicle-control information signals and non-vehicle control information signals can be prioritized according to a plurality of sequentially processed urgency levels. The vehicle-control information signals are assigned higher urgency and the non-vehicle-control information signals are assigned lower urgency.
