<P>PROBLEM TO BE SOLVED: To solve insufficient power generation of a generator caused by a shift schedule such as a traction control and the like when a driven wheel is driven by a electric motor driven by the power generated by the generator. <P>SOLUTION: The front wheels are driven by an engine 2 via an automatic transmission 4, the rear wheels are driven by a DC motor 3 via an electromagnetic clutch 12 and the DC motor 3 is driven by the power generated by the generator 7. The shift schedule of the automatic transmission 4 is changed from a regular shift schedule of a regular transmission line to the shift schedule setting a first or second TCS (Traction Control System) transmission line in a higher car speed side than the regular transmission line by starting the traction control. However, while continuing the four-wheel drive control, the changed shift schedule prohibits the change to the regular shift schedule side so as to prevent the insufficient power generation of the generator. <P>COPYRIGHT: (C)2004,JPO |
