PURPOSE:To suppress the speed change shock by calculating an aimed engine revolution speed from the car speed during speed change and the gear ratio of a transmission after speed change and controlling a throttle actuator so that the throttle opening degree corresponding to the revolution speed is obtained. CONSTITUTION:A gear type transmission 1 is equipped with a shift actuator 6 for speed change and a selector actuator 7, and further a clutch actuator 8 for connecting and disconnecting a clutch between an engine E and the transmission 1. Further a throttle actuator 10 for adjusting the opening degree of the throttle of the engine E is installed. These actuators 6-8 and 10 are controlled by an electronic controller 5 according to the engine operation state. In such an engine, the input shaft revolution speed of the transmission 1 is calculated from the car speed in speed change and the gear ratio of the gears after speed change, and the throttle opening degree is controlled by the throttle actuator 10 so that the engine revolution speed accords with the input shaft revolution speed. |
