<P>PROBLEM TO BE SOLVED: To improve the efficiency of a whole vehicle while suppressing deterioration of efficiency due to the thermal influence of two motor generators as much as possible. <P>SOLUTION: This control unit of a hybrid car is provided with a first temperature sensor SW5 for detecting the temperature of a first motor generator MG1; a second temperature sensor SW6 for detecting the temperature of a second motor generator MG2; an operating state discrimination means 51 for detecting the operating state of the hybrid vehicle 1; a driving source selection means 52 for selecting any one out of an engine 10 and the first and second motor generators MG1 and MG2 which can be operated based on the decision of the operating state discrimination means 51; and a motor load distribution means 56 configured to decide the temperature states of the motor generators MG1 and MG2 based on the detection signals of the first and second temperature sensors SW5 and SW6, and to, when the temperature of the selected motor generator is a predetermined temperature T<SB>ST</SB>or more, determine the load distribution of the motor generator so that the load of the motor generator whose temperature is high can be reduced while maintaining whole torque. <P>COPYRIGHT: (C)2009,JPO&INPIT |
