Spacing distance control device

(57) Abstract: The apparatus of the present invention, depending on the traveling speed, determine the target distance or a target time interval with respect to the preceding vehicle. Gap distance control, when determining the target distance or a target time interval, is performed on the basis of the minimum distance or minimum time interval given beforehand given previously by the driver. The distance feeling of the driver is dependent on the visibility state of the current, visibility condition is poor (poor weather, dark), the spacing distance control, the target distance or a target time interval is determined for normal vision state increase.
