Abstract
A device for the radio-transmission of a hazard warning to the driver of a motor vehicle includes a data transmission device for transmitting and receiving data. The data transmission device exchanges data with data transmission devices of other motor vehicles, including data to warn other motor vehicles of the hazard, evaluates received data and outputs warning signals to the driver when a hazard is detected. The transmitted data includes information on the position, speed and direction of travel of the transmitting motor vehicle, as well as the type of road on which the transmitting motor vehicle is moving. The information on the position, the type of road and the direction of travel is generated by a navigation system. A warning zone around the current position of the transmitting vehicle is calculated by a computer unit and emitted by means of the data transmission device.
