<P>PROBLEM TO BE SOLVED: To expand a speed area allowing selection of a mode for travel operated only by a motor. <P>SOLUTION: A second driving force transmission part 16 is set so that its deceleration ratio to a rotational shaft 12a in the motor 12 is higher than that of a first driving force transmission part 15. When a vehicle velocity V is not less than a predetermined first low limit velocity VL1 and not more than a first high limit velocity VU2, an ECU 19 connects an internal combustion engine 11 and a transmission 13 together by means of a main clutch 14, connects a first driving shaft gear 15a to the rotational shaft 12a by means of a first clutch 17, and separates a second driving shaft gear 16a from a driving shaft P by means of a second clutch 18. When the vehicle velocity V is not less than a predetermined second low limit velocity VL2 and not more than a second high limit velocity VU2, the ECU 19 separates the internal combustion engine 11 and the transmission 13 from each other by means of the main clutch 14, integrates the rotational shaft 12a with an input shaft 13a by the first clutch 17, and connects the second driving shaft gear 16a to the rotational shaft 12a by means of the second clutch 18. <P>COPYRIGHT: (C)2003,JPO |
