Abstract (en)
[origin: DE19750942A1] Road vehicles are equipped with transmitter/receivers and when a number of them are traveling in a column one of them acts as a reference vehicle. Each vehicle has identification data and means of transmitting data such as speed and distance. This enables warnings of hard braking or sudden changes in speed to be relayed to vehicles not within sight of each other.
