PROBLEM TO BE SOLVED: To perform acceleration or deceleration using the maximum driving force of a vehicle during acceleration or deceleration control by setting an increase in a vehicle speed command value according to the vehicle speed deviation of a detected vehicle speed value from a vehicle speed command value, using a vehicle speed command value setting means. SOLUTION: The condition of a constant-speed driving control flag is checked (S6). When the constant-speed driving control flag is set, acceleration control is performed (S7), and then coast control is performed (S8). Next, based on a vehicle speed command value and actual vehicle speed, a desired driving force for making them coincide is computed (S9). Then desired engine torque is computed, and a throttle opening command value is computed from the desired engine torque and engine speed (S10). Then a throttle opening deviation (actual opening minus opening command value) is calculated, and a PWM duty ratio is computed based on the calculated deviation (S11), whereby a vacuum pump motor and a vent valve solenoid are pulse driven. |
