CONTROL APPARATUS AND CONTROL METHOD FOR AUTOMATIC TRANSMISSION |
摘要 |
An ECU executes a program including the steps of: starting monitoring the turbine revolution speed and the output shaft revolution speed when a direct shift is started (YES in S100) (S102); performing complete disengagement control on a disengagement element (1) (S106), lowering control pressure of a disengagement element (2) to preliminarily fixed control pressure (S110); starting engagement control on an engagement element (1) when a set time period Is (1) passes (YES in S112) (S114); performing complete disengagement control on the disengagement element (2) when a set time period Is (2) passes (YES in S118) (S120); and starting the engagement control on an engagement element (2) when turbine revolution speed NT is equal to or larger than (the synchronous revolution speed of a gear after a shift—a set value Ns) (YES in. S 122) (S 124). |
