PROBLEM TO BE SOLVED: To reduce apparatuses for driving each on-board auxiliary machine in an engine room for a generator for charging batteries as a power source for a running motor and in an electric vehicle with a generating engine installed for driving the generator. SOLUTION: When an oil pressure of a hydraulic tank 49 is lower than the prescribed pressure in a power steering mechanism, a generator engine 39 is driven and a hydraulic pump 41 is driven, and the oil pressure is stored in the hydraulic tank 49. Also, when a negative pressure of a negative pressure tank 51 in a booster mechanism of a hydraulic brake drops below a prescribed pressure, the power generating engine 39 is driven and a sucked negative pressure is stored in the negative pressure tank 51. Moreover, when air conditioning or heating is required, based on an outside air temperature, set temperature and the quantity of solar radiation, the generator's engine 39 is driven and a compressor 43 of an air conditioner is operated. |
