PROBLEM TO BE SOLVED: To determine the feed time and the preparation pressure required to complete the invalid stroking work to an optimum, to realize the invalid stroking work with little variance and excellent responsiveness, to effectively reduce the shifting shock, and to give favorable adaptation to the feeling of occupants. SOLUTION: The feed time (the preparation completion time) T1 is map- retrieved from the input shaft number of revolution NM and the ATF temperature (S400), the preparation pressure QDB1A is map-retrieved from similar parameters (S402), the remaining oil quantity OILn of a clutch is estimated (S404), the preparation completion time is corrected from the estimated oil remaining quantity (S406), and the preparation pressure is supplied in the corrected time to achieve the invalid stroking work. |
