In the vehicle of the present invention, when the driver releases the depressed accelerator pedal, the drive control sets the vehicle speed V at that time as the target vehicle speed V* (step S440). The engine and the motor for outputting driving force are controlled to drive the vehicle at the target vehicle speed V*. When the driver steps on the relaxed brake pedal, the drive control stores the target vehicle speed V* set before the driver depresses the brake pedal as the previous target vehicle speed Vpre and cancels the setting of the target vehicle speed V* (steps S470 and S480 ). In response to the driver's subsequent release of the brake pedal, the drive control sets the vehicle speed V at this time as the target vehicle speed V* (step S510) and resumes constant speed (cruising) driving. When the driver turns the steering wheel to or beyond a predetermined degree for left or right turn, the driving control sets the previous target vehicle speed Vpre to the target vehicle speed V* (step S520) and restarts the constant speed driving. This arrangement ensures easy and quick start of constant speed (cruising) driving and enables constant speed (cruising) driving according to changes in the driving state.
