PURPOSE:Absorb a difference of driving torque caused by a difference between speed change ratios before and after the speed change so as to decrease any shock during speed change by setting respective driving torques before and after the speed change to equal values and suppress torque variation during the speed change. CONSTITUTION:A device main body is composed of the controller 7 of a speed changer 12 and the control unit 10 of an engine 11. An electronic throttle 8 for regulating an intake air quantity of an engine 11 is controlled by the control unit 10 based on respective detection signals of a vehicle speed sensor 14, an accelerator opening sensor 15, a speed changer input shaft rotational speed sensor 16, and an engine rotational speed sensor 17. The target driving torque, speed changer input shaft torque, target engine torque, shock reduction torque at the time of speed change, and throttle opening are calculated in the control unit 10 by the respective calculation parts 1-5, and fuel injection and ignition are controlled by a control part 6. In this case, respective driving torque before and after the speed change are set to equal values, and torque variation during speed change is suppressed. |
