<p>An object of the invention is to improve the speed change control characteristics of a vehicle fitted with an automatic transmission. With the present invention, after speed change judgment (after a speed change command), a currently set throttle opening (TVO_REF) is gradually decremented to a final target by predetermined throttle decrement amounts (TVODDWN), and from after commencement of a gear change period is detected the throttle opening is returned to a target throttle opening (TVO_REF1) which is based on the accelerator operation of the driver. Therefore, even if there is a response delay in an automatic opening control of a throttle valve, then at the time of completion of the gear change period, the throttle opening can be controlled to the target throttle opening which is based on the accelerator operation of the driver. Therefore the possibility as with the conventional arrangement of the occurrence of a torque pull after completion of the gear change period and an increase in speed change shock so that the driver is subjected to a different feeling, can be reliably eliminated. <IMAGE></p> |
