  • first detecting means for detecting respective velocities of the vehicles and the vehicle distance therebetween;

    calculating means for calculating a desirable distance to be kept between the vehicles based on the respective velocities of the vehicles detected by the first detecting means;

    warning means for producing a warning when an actual distance is smaller than a warning distance which, in turn, is larger than the desirable distance by a predetermined value; and

    setting means for automatically controlling the warning distance so that it increases as a velocity difference between the respective velocities of the vehicles is increased.
