Abstract: According to the invention, the security and driving comfort on driving road vehicles is increased by the fitting thereof with automatic systems for distance control and traffic separation. The operating properties of vehicles filled with such systems may be better adapted to traffic users merging into the lane thereof and the operating properties essentially better matched to those of a human vehicle driver, whereby an automatic traffic separation is carried out in which the position and speed of objects and traffic users are detected by a separation sensor. The vehicle is then subjected to a braking or acceleration, depending on said detected information.
