发明名称 Control apparatus and control method for continuously variable transmission
摘要 In order to suppress the clutch applying shocks at a garage shift time of a continuously variable transmission equipped with a hydraulic type forward-backward switching device, an ECU starts a timer of a predetermined time period, when the engine starts. If the garage shift occurs before a timer-up, the ECU starts a standby oil pressure control to feed the forward-backward switching device with a standby oil pressure lowered to such a level as to leave the forward-backward switching device unapplied. The ECU calculates a first fill hydraulic value in accordance with the time period from the engine start to the garage shift operation. After the time up, the ECU ends the standby oil pressure control, and executes a first fill control at the first fill hydraulic value calculated.
