VEHICLE, AND CONTROL METHOD AND CONTROL APPARATUS FOR AN AUTOMATIC TRANSMISSION

摘要

An ECU executes a program including the steps of: if downshift from a fifth gear implemented when a B3 brake and a C2 clutch both engage to a second gear implemented when a C1 clutch and a B1 brake both engage is done, or downshift from a sixth gear implemented when the B1 brake and the C2 clutch both engage to a third gear implemented when the C1 clutch and the B3 brake both engage is done (YES at S100), disengaging a frictional engagement element other than the C2 clutch, i.e., the B3 brake or the B1 brake (S104); and decreasing an engagement pressure that is applied to the C2 clutch to a reference value of target engagement pressure (S106).
