Abstract
The vehicle is provided with a radar unit for detecting an obstacle existing ahead in the course of the running way along which the vehicle is running. When the radar unit detects a variation in its detectable region, such as a detectable distance or a detectable area range in left and right directions, from the detectable region to be detectable during ordinary running, a safety unit such as an alarm unit or an automatic brake unit is operated. A control logic for operating a collision-avoiding system for avoiding a collision with the obstacle existing ahead, such as an alarm unit or an automatic brake unit, is altered to a safe side on which safety in driving the vehicle is improved, when the detectable region is varied.
