PURPOSE:To prevent collision against an obstacle by limiting the maximum speed to a predetermined value according to a signal fed from a sensor for detecting an object existing in the detection area in the running direction of a vehicle. CONSTITUTION:An object detecting sensor 19 is mounted in the front center of the steering shaft of a vehicle 1. The object detecting sensor 19 detects an object existing in the detection area thereof and produces a detection signal which is then transmitted to a drive control means for limiting the maximum speed to a predetermined level. If an object is detected when the vehicle is running at higher speed than the limit speed, the speed is controlled automatically and thereby the vehicle can be braked before it collides against the object or can steer clear of the object. By such arrangement, safety running can be carried out and collision against an obstacle such as a pedestrian can be prevented.
