PROBLEM TO BE SOLVED: To obtain the controller of a hybrid vehicle, where its engine and its motor-generator having as a power source a high-voltage battery are provided, and when charging by its motor-generator in the case of its deceleration the high-voltage battery and a low-voltage battery for its mounted electric load, the overcharges of these batteries and its over-deceleration are prevented, and its regenerative electrical energy is also taken efficiently. SOLUTION: By a desired charging current calculating means 23, a desired charging current is calculated, corresponding to the charge state of a high- voltage battery to regulate its charging current by a first current-limiter means 24 having a certain limiting current value. Then, by an electrical load current sensing means 27, an electrical load current fed to an electric load mounted on a hybrid vehicle is detected. Subsequently, by adding to each other through desired-generation-current sensing means 28, 30 the desired charging current and the electrical load current, the desired-generation current of the motor generator of the hybrid vehicle is calculated, to regulate it by a second limiter means 31 having a limiting current value which responds to the rotational speed of the engine of the hybrid vehicle, the turning on/off of its air- conditioner, and its gear ratio. |
