Abstract
A vehicle cruising control device includes a detecting device for detecting the current speed of the vehicle, a constant speed control device for maintaining the speed of the vehicle at a selected speed, a measuring device for measuring the current inter-vehicle distance between the vehicle and an advance vehicle and an inter-vehicle distance control device for maintaining the inter-vehicle distance between the vehicle and the advance vehicle at a predetermined distance based on the degree of danger determined by the relationship of the current distance between vehicles and the relative speed between the vehicles. A switching device is provided for turning on either of the constant speed control device and the inter-vehicle distance control device.
