PROBLEM TO BE SOLVED: To make an acceleration control in the form of a follow-up control for a foregoing vehicle, which is performed in suiting a driver's running sense in the case a state capturing the preceding vehicle is changed to a state of not capturing. SOLUTION: In a state that the preceding vehicle is captured, a driving force control is conducted so that an inter-vehicle distance D sensed by an inter-vehicle distance sensor is identical with its target value D*. When a state of the follow-up running becomes the state not capturing the foregoing vehicle, an initial accelerationαsi having a greater value is calculated in reference to an acceleration calculation map on the basis of an own vehicle speed Vs at this time, and the acceleration control is performed on the basis ofαsi. A sense of incompatibility is prevented to be given to the driver while satisfying responsiveness by lowering the accelerationαwith increasing the own vehicle speed Vs.
