<P>PROBLEM TO BE SOLVED: To provide a control device for a vehicle, eliminating a bad influence upon vehicle control due to a change in temperature of a driving source itself such as an electric motor and its environmental temperature. <P>SOLUTION: In a hybrid vehicle HV, which speed-shifts the output of a motor/generator MG2 using an automatic transmission 3 and transmits the speed-shifted output to a drive wheel 7, a magnet temperature of the motor/generator MG2 is estimated, and when the magnet temperature is higher than a reference temperature, an oil pressure command value for engaging or disengaging a brake B1, B2 of the automatic transmission 3 is corrected in a decreasing direction, thereby preventing tie-up shock. When the magnet temperature is lower than the reference temperature, on the other hand, the oil pressure command value for engaging or disengaging the brake B1, B2 of the automatic transmission 3 is corrected in an increasing direction, thereby avoiding racing in the motor/generator MG2. <P>COPYRIGHT: (C)2009,JPO&INPIT |
