PROBLEM TO BE SOLVED: To achieve a hybrid vehicle control device, that is capable of preventing overcharging and overdischarging of a main battery and that enables extension of service life of the battery, so that reliability of the entire system can be improved. SOLUTION: In a vehicle having an engine as a vehicle-propelling device and a motor, which is connected to the output shaft of this engine, which has driving and generating functions, an engine control means that controls the operation state of the engine and a motor control means that controls the drive state of the motor are provided, independently of the control of the engine by the engine controlling means. Functions for detecting the open-circuit voltage of a main battery, when the motor operation is stopped and setting the upper limit and lower limit voltage when the motor is operated according to the open-circuit voltage of the main battery, are added to the motor control means. |
