In system and method for an automotive vehicle equipped with the system and defined as a system vehicle, an inter-vehicle distance from the system vehicle to a preceding vehicle traveling ahead of the system vehicle is detected, a velocity of the system vehicle is detected, a determination is made whether the system vehicle is running to follow up the preceding vehicle at a target value of the inter-vehicle distance, a control system for performing a feedback control of the detected value of the inter-vehicle distance to the target value thereof is provided, a target value of the velocity of the system vehicle is outputted, a control gain of the feedback control system being modified according to the detected value of the inter-vehicle distance and a result of a determination whether the system vehicle is running to follow up the preceding vehicle at a target value of the inter-vehicle distance and a braking force and a driving force of the system vehicle are controlled so as to make a detected value of the system vehicle velocity coincident with the target value of the velocity of the system vehicle.
