Abstract
In a radio-based device for issuing hazard warnings to the driver of a vehicle a data receiver situated on board the vehicle receives hazard data from a data transmitter of at least one other vehicle, and evaluates the received data in a computer unit. The received data includes information about the position, speed and direction of travel of the transmitting vehicle. According to the invention, from the received data of the transmitting vehicle and from information relating to the position, speed and direction of travel data of the receiving vehicle, a relevance measure is determined in the receiving vehicle, which relates to whether the transmitting vehicle is located on a section of road lying ahead of the receiving vehicle. A chronological profile of the relevance measure is determined by repeatedly determining the relevance measure.
