PROBLEM TO BE SOLVED: To make it possible to improve the learning accuracy of a lock-up clutch pressure learning control and to suppress a reduction in the learning frequency of the lock-up clutch pressure learning control.SOLUTION: At a time of executing a L/U clutch pressure learning control, the learning accuracy of the L/U clutch pressure leaning control can be improved by prohibiting the engagement of an L/U clutch in a running state in which an excessive variation in an engine revolving speed Ne due to gearshift of a continuously variable transmission tends to occur during learning. Furthermore, at the time of executing the L/U clutch pressure learning control, it is possible to suppress a reduction in the learning frequency of the L/U clutch pressure learning control not only by simply prohibiting the engagement of the L/U clutch in the running state in which the excessive variation in the engine revolving speed Ne due to the gearshift by the continuously variable transmission but also by engaging the L/U clutch after the running state transitions to a running state in which it is difficult for the excessive variation to occur during the learning. |
