A distance control system of a vehicle includes: a signal transmitter for transmitting wireless signals forward with respect to a distance-controlled vehicle; a signal receiver for receiving the wireless signals reflected and returned from an object vehicle; a relative velocity measuring unit for measuring the relative velocity of the object vehicle in relation to the distance-controlled vehicle on the basis of the received wireless signals; a vehicle-to-vehicle distance measuring unit for measuring a first vehicle-to-vehicle distance between the distance-controlled vehicle and the object vehicle; and a vehicle-to-vehicle distance calculating unit for calculating a third vehicle-to-vehicle distance based on the first vehicle-to-vehicle distance and a second vehicle-to-vehicle distance calculated from the relative velocity.
