ABSTRACT:
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.
