PROBLEM TO BE SOLVED: To prevent a speed change shock at the time of starting at a mode, snow mode for example, to start at a speed stage of the higher speed side than a normal speed stage by setting a working state of a control valve and a changeover valve in a non-driving range same as a working state to set a speed stage for starting. SOLUTION: An electronic control device for an automatic transmission is devised to judge ON/OFF of a speed stage and a lock-up clutch in accordance with an input data and a previously memorized speed change map, or to judge an adjusting level of line pressure, to output an indication signal to specified solenoid valve in accordance with its judgment result and to judge failure and control in accordance with it. Conversely, an electronic control device 8 for an engine controls opening of a subthrottle valve 5 in accordance with an input data, reduces fuel injection quantity at the time of speed change by the automatic transmission 1 or lowers output sorque by reducing opening of the subthrottle valve 5. |
