In step S3, the engine rotation speed detection signal value is set to a predetermined value N.
When the engine load is equal to or higher than e (engine high load state), the process proceeds to step S5 even if the vehicle is substantially at a standstill, and normal shift control (predetermined in advance by the vehicle speed detection signal value and throttle opening detection signal value) is performed.

As a result, the current 2nd speed gear ratio is shifted to the 1st speed gear ratio based on normal speed change control. Therefore, even if the vehicle is set to the second gear ratio, the vehicle starts smoothly from the first gear ratio. Further, as long as the vehicle speed detection signal value from the vehicle speed detector 18 is equal to or higher than the predetermined value vO, the process proceeds from step S2 to step S5, and normal gear shift control is continued regardless of the engine rotation speed detection value.

Further, in addition to the engine speed detection signal from the engine speed detector 14, an accelerator switch may be provided that opens and closes in conjunction with the depression of an accelerator pedal (not shown) to detect the engine load state. . In this case, detection signals from the engine rotation speed detector 14 and the accelerator switch are applied to the electronic control unit 13 via an OR circuit. As a result, even if either the engine speed detector 14 or the accelerator switch malfunctions, the automatic transmission 11 will not be able to move to a high gear ratio when the vehicle is stopped and return to the lowest gear ratio when starting. It will be ensured that there will be no hindrance.
