PURPOSE: A control device for distance between vehicles is provided to control the distance by detecting in the entire control range with a long distance radar sensor and a short distance ultrasonic sensor without interference, and to relieve driving load by automatically controlling the distance between the vehicles. CONSTITUTION: A distance control device of a vehicle is composed of a travel information detecting unit(100) detecting the travel condition of the vehicle, a first distance detecting unit(102) installed in the front of the vehicle to detect the distance from the preceding vehicle, a second distance detecting unit(104) symmetrically installed to the first distance detecting unit to detect the distance from the preceding vehicle, a distance control unit(110) analyzing first and second forward distance signals from the first and second distance detecting units and the travel condition signal from the travel information detecting unit and outputting the travel condition control signal to control cruise of the vehicle according to the distance from the preceding vehicle, and a distance adjusting actuator(120) regulating cruise of the vehicle and adjusting the distance according to the travel condition control signal.
