When the operating speed of an accelerator pedal is higher than a given operating speed, a target acceleration as a target output value is multiplied by a gain so that an absolute value of the target acceleration is increased; therefore, a large acceleration requested by the driver can be achieved. The gain by which the target acceleration is multiplied is set to 1 when the target acceleration is about zero, so as to resume a condition where the absolute value of the target acceleration is not increased. Thus, when the control of increasing the absolute value of the target acceleration with the gain is stopped, an elevation change is less likely or unlikely to occur in the actual acceleration. Consequently, a desired acceleration is generated without causing the driver to feel uncomfortable during driving of the vehicle.
