<P>PROBLEM TO BE SOLVED: To improve early temperature rising of a battery while suppressing deterioration of fuel consumption as much as possible at the time of cold starting of a vehicle in a hybrid vehicle provided with a dual fuel engine capable of switching hydrogen as fuel to be used and gasoline whose engine torque at the time of usage is large compared with the hydrogen. <P>SOLUTION: A battery temperature sensor is provided, then a drive control of the engine is performed so that charge or discharge of a battery is executed by a battery controller when temperature detected by the battery temperature sensor is not higher than a predetermined setting temperature (YES in the step SB13), and the fuel used for the engine is made to be the gasoline when the charge of the battery is performed (NO in the step SB15), while the fuel to be used for the engine is made to be the hydrogen when the discharge of the battery is performed (YES in the step SB15). <P>COPYRIGHT: (C)2008,JPO&INPIT |
