<P>PROBLEM TO BE SOLVED: To secure cooling capability according to the heat generating value of a motor in a hybrid car. <P>SOLUTION: In the hybrid car 100, which includes a mechanical oil pump 32 for generating an oil pressure to be driven with a mechanical driving force from an engine 16 and supplying hydraulic fluid to motor generators MG1 and MG2 to perform cooling and lubrication, the calculation of the first flow rate of the hydraulic fluid based on the rotating speed of an engine 16 and the calculation of the predicted heating values of the motor generators MG1 and MG2 based on the operating states of the motor generators MG1 and MG2 and the calculation of the second flow rate of the hydraulic fluid necessary for cooling the predicted heating values is performed, and the rotating speed of the engine 16 is controlled so that the flow rate of the hydraulic fluid can approach the second flow rate based on the result of the comparison of the first flow rate and the second flow rate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
