Zusammenfassung:	PROBLEM TO BE SOLVED: To achieve an automatic transmission during the EV mode traveling by providing a transmission drive to selectively set the gear ratio of a transmission, a clutch drive to joint/disjoint a second clutch, and a transmission control circuit to give the electric signal for control to the transmission drive and the clutch drive. SOLUTION: When a transmission 6 is in the neutral position, a clutch drive 36 is operated to set a second clutch 22 in the off-condition. When the transmission 6 is engaged with a traveling gear, the rotational speed of an output shaft of a power connection gear 7 is calculated by a vehicle speed sensor 30, and the rotational speed of a second electric generator 2 is received from a second rotation sensor 32. The rotational speeds of two shafts of the second clutch 22 opposite to each other are substantially equal to each other based on the rotational speed of the output shaft. A transmission drive 35 is driven by controlling a transmission control circuit 40 to set the second clutch 22 in on-condition.
