PROBLEM TO BE SOLVED: To provide acceleration performance along a feeling of a driver by varying an acceleration according to a state of preceding vehicle leaving when deciding that a preceding vehicle has left during follow travel control to transfer to a constant-speed travel control. SOLUTION: When recognizing the preceding vehicle by a forward recognition device 3 having a stereo camera 3a loaded in one's own vehicle 1, the follow travel control to follow the preceding vehicle is performed. When the preceding vehicle has relatively left by a course change of the own vehicle 1 to a right-side travel lane during the follow travel control (S1-S3) when performing the constant-speed travel control to travel with a preset set vehicle speed as a target vehicle speed when the preceding vehicle is not recognized, a one's own vehicle in-leaving speed increase correction valueβthat is a larger value than a preceding vehicle in-leaving speed increase correction valueαis added to a present target vehicle speed Vtg to make the target vehicle speed Vtg largely skip (S5), and thereafter the target vehicle speed Vtg is increased to the set vehicle speed at a prescribed acceleration.
