PROBLEM TO BE SOLVED: To improve shifting performance when a re-shifting request occurs such as cancellation of connection transition from normal connection to sudden connection during pre-charge control in connecting a frictional engagement element. SOLUTION: When a re-shifting request occurs during the pre-charge control, designated pressure is changed step by step to the standby pressure (critical pressure) after pre-charge control, and the designated pressure after the step change is taken as the initial pressure, re-shifting processing is started. |
