<P>PROBLEM TO BE SOLVED: To provide a controller of a hybrid vehicle which prevents an energy storage device from being overcharged. <P>SOLUTION: The controller of the hybrid vehicle includes a high voltage battery 5 for charging and discharging a power in association with drive or regeneration of a traveling motor 1, an engine drive compressor 19 which can be operated by a power of the engine 2, and an air conditioner 14 for the vehicle having a motor operated compressor 16 which can be operated by the power of the motor. An ECU 11 judges whether or not the high voltage battery 5 is an overcharging state or not according to whether input and output voltage Vbatt of the high voltage battery 5 is raised to a specified value or more. If the high voltage battery 5 is judged to be the overcharging state, the ECU 11 performs a temperature regulation in the vehicle by operating the motor operated compressor 16 when there is the operation request of the air conditioner 14 and the motor operated compressor 16 can hold required air conditioning performance, and continues the discharging process of the high voltage battery 5 by the motor operated compressor 16 until the overcharging state is eliminated. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
