PURPOSE:To invariably perform the follow running control of a vehicle after a preceding vehicle stably by assuming that the preceding vehicle is located on the running path of this vehicle near the boundary of the inter-vehicle distance when no preceding vehicle exists in the preset inter-vehicle distance, and controlling this vehicle for acceleration or deceleration. CONSTITUTION:A vehicle is accelerated or decelerated by an accelerating/decelerating device A for the follow running of this vehicle after a preceding vehicle. The inter- vehicle distance between this vehicle and the preceding vehicle is detected by a sensor B. The vehicle speed of this vehicle is detected by a sensor C, and the steering angle of this vehicle is detected by a sensor D respectively. When the preceding vehicle exists in the preset detection region, the proper control quantity of the accelerating/ decelerating device A for the follow running after the actual preceding vehicle is determined by a means E based on the detected inter-vehicle distance and the detected vehicle speed. When no preceding vehicle exists in the preset detection region, the proper control quantity for the follow running after a virtual preceding vehicle is determined by the means E based on the detected vehicle speed and the detected steering angle respectively. The accelerating/decelerating device A is controlled by a means F in response to the determined control quantity.
