Abstract
A control device of a hybrid vehicle is provided, capable of detecting the over-discharge state of the battery and controlling the charging and discharging rates of the battery for protecting the battery. The control device of the hybrid vehicle comprises an engine which outputs propulsive force to the vehicle, a motor which is directly connected to said engine and which assists the output of the engine, a battery which supplies the electric power to said motor and which is charged by electric energy generated by activating said motor as a generator when the assisting driving force is not necessary, an electric load whose electric energy is supplied by electric power generated by the motor and the battery, and a battery protecting device which increases the rotation speed of said engine when the over-discharge of said battery is detected and which stops supplying the electric power to said electric load when the over-discharge further advances.
