摘要:
In order to suppress an engagement shock of a clutch at the time of garage shifting in a continuously variable transmission including a hydraulic forward/reverse driving switching device, when an engine starts up (YES in S100), an ECU starts a timer having a predetermined time period (S102). When the garage shifting is done before the timer up (YES in S104 and NO in S106), the ECU starts waiting hydraulic pressure control in which a waiting hydraulic pressure reduced to such an extent that the forward/reverse driving switching device is not engaged is supplied to the forward/reverse driving switching device (S110), and calculates a fast fill hydraulic pressure value in accordance with a time period from the engine startup to the garage shifting operation (S114). After the timer up (YES in S116), the ECU ends the waiting hydraulic pressure control (S118) and exercises fast fill control at the calculated fast fill hydraulic pressure value (S120).
