<P>PROBLEM TO BE SOLVED: To raise a temperature of cooling oil of an electric motor 13 without separately providing a heat source. <P>SOLUTION: In an HV-ECU 18 controlling cooperation relation between an engine 10 and the electric motor 13 of a hybrid automobile 1 traveling by cooperation between the engine 10 and the electric motor 13, the cooling oil 19 cooling the electric motor 13 remains inside the electric motor 13. When the temperature of the cooling oil 19 is not more than a prescribed temperature or less than the prescribed temperature and when an SOC (State of Charge) of a battery 15 is not more than a prescribed range or less than the prescribed range, the HV-ECU 18 makes the engine 10 drive the electric motor 13 as a power generator. When the temperature of the cooling oil 19 is not higher than the prescribed temperature, and when the SOC of the battery 15 is not lower than the prescribed range, the HV-ECU 18 executes the travel by the electric motor 13, or the travel wherein the engine 10 and the electric motor 13 are used together. <P>COPYRIGHT: (C)2011,JPO&INPIT |
