<p>PROBLEM TO BE SOLVED: To reflect in real time an acceleration intention and mode selection in a shift control even in a automatic transmission which is combined with engine with mode selection type electronic control throttle. SOLUTION: An engine controller 6 controls a throttle opening VTO via a step motor 4 so as to realize a target throttle opening (y) with respect to an accelerator pedal depression amount (x) every mode selected by a switch 9. A transmission controller 17 uses the accelerator pedal depression amount (x) representing an acceleration intention and a mode selection signal selected by the switch 9 as engine output information, predicts the target throttle opening (y) based on the engine output information, obtain a target transmission gear ratio i* based on the target throttle opening (y) and vehicle speed VSP to command an actuator 16 for a shift control. Accordingly, the acceleration intention and mode changeover can be reflect in real time in the shift control.</p> |
