<P>PROBLEM TO BE SOLVED: To prevent the overheating of a generator motor in a driving device equipped with an automatic transmission, an internal combustion engine and the generator motor. <P>SOLUTION: The driving device 20 is provided with: a CVT 50 for performing a shift between an input shaft 51 and an output shaft 52; an engine 22 equipped with a crankshaft 24 connected to the input shaft 51; and a motor 40 equipped with a rotary shaft 41 connected to the input shaft 51. In this driving device 20, while the engine 22, the motor 40 and the CVT 50 are controlled so that the output shaft 52 can output target power and so that the motor 40 can output target electric power, the transmission gear ratio of the CVT 50 is changed according to the temperature of the motor 40, so that the temperature of the motor 40 can be prevented from exceeding an allowable critical temperature. <P>COPYRIGHT: (C)2008,JPO&INPIT |
