PURPOSE:To promote the improvement of drivability, by setting a target car speed such that the lower is a car speed the smaller the target car speed decreases its value and suppressing an engine output from its rapid change in the low car speed when the target car speed is set for an accelerator control amount. CONSTITUTION:A control unit 25, which inputs detection values from an accelerator sensor 26 detecting a step in amount of an accelerator 5, car speed sensor 27 and a throttle sensor 28, controls the opening of a throttle valve through a throttle actuator 18 so as to obtain a target car speed corresponding to an accelerator step in amount. When the target car speed is set corresponding to the accelerator step in amount, the control unit 25, which sets the target car speed where, the lower the car speed the smaller the target car speed decreases in upper and lower limit values, preventing an engine output from change at the time of the low car speed.
