ABSTRACT:
An automatic transmission control unit switches on and off operations for a plurality of solenoids in response to combinations of throttle openings estimated on the basis of an output of a throttle sensor and vehicle speeds estimated on the basis of an output of a vehicle speed sensor to set a proper speed change gear. The automatic control unit sets second gear when a vehicle is stopped to suppress creep during the stoppage of the vehicle, and starts the vehicle with the second gear as it is when the changing rate of the throttle opening is small. When the changing rate of the throttle opening exceeds a predetermined rate in an acceleration state, it is determined that an operator desires powerful acceleration and hence the operation is shifted to first gear. In contrast, when the operator requires a slow start, a second gear start is automatically selected without permitting down-shift to the first gear every time the vehicle is started.
