Abstract:
Power train control unit 100 controls friction clutch 203 when shifting from one cogwheel row to the other cogwheel row, sets the target synchronous rotation speed based on the output rotation speed of a transmission and parameters indicative of the state of engine 1 or the transmission, and sets the command value to the friction clutch so that the input rotation speed can be synchronized with the target synchronous rotation speed. Control unit 100 sets the target shifting required time based on parameters indicative of the state of engine 1 or the transmission, and corrects the command value to the friction clutch so that the required shift time can approach the above target shift required time.
