ABSTRACT:
An ECU executes a program including a step of detecting a running speed of a vehicle and a current gear stage of the vehicle, a step of determining whether or not shifting is required, a step of calculating a required period T(D) for performing double clutch control if shifting is required, a step of calculating a required period T(S) for synchro-rotational synchronization, a step of determining whether or not the required period T(D) for double clutch control is equal to or shorter than the required period T(S) for synchro-rotational synchronization, and a step of carrying out shifting by performing double clutch control if the required period T(D) for double clutch control is equal to or shorter than the required period T(S) for synchro-rotational synchronization. A sense of incongruity felt by a driver during shifting is thereby suppressed.
