<P>PROBLEM TO BE SOLVED: To improve the energy efficiency of the entire vehicle by warming up a planetary gear using the heat from a motor which is disposed to transfer the heat to the planetary gear and outputs power to a drive shaft through the planetary gear, for improved drive efficiency of the planetary gear. <P>SOLUTION: A creep torque Tcr outputted from a motor is set according to an oil temperature To (S112) if a shift position is in a drivable position, with an accelerator being off, and a brake on, and the travel condition of the vehicle is in the region to permit outputting of a creep torque (S100-S104), while the oil temperature To of a lubricator that lubricates the planetary gear is equal to or above a prescribed temperature Toref and an SOC of a secondary battery which supplies power to the motor is equal to or above a prescribed amount Sref. The creep torque Tcr is so set as to rise as the oil temperature To falls. <P>COPYRIGHT: (C)2004,JPO |
