To maintain a suitable vehicle separation between a driven vehicle and a preceding vehicle, a controller predicts a closest approach distance between the driven vehicle and the preceding vehicle on the assumption that the preceding vehicle decelerates at a deceleration detected by a sensor and that the driven vehicle decelerates at a prescribed assumed deceleration after running at a speed detected by the vehicle speed sensor for an idle running time. The controller predicts the speed at the time of closest approach when the separation between the preceding vehicle and the driven vehicle is the closest approach distance. A suitable vehicle separation is determined based on the predicted speed at the time of closest approach and a previously set length of time, and when the predicted closest approach distance is smaller than the suitable vehicle separation, a warning or braking force is generated.
