<p>A vehicle is provided including a high-voltage battery for a motor/generator power source, a low-voltage battery for electrical loads, an inverter for controlling the motor/generator, sensors which detect a condition of the high-voltage battery, a rotation speed of the engine, a vehicle speed, and a depression of an accelerator pedal, and a microprocessor. The microprocessor is programmed to compute a state of charge (SOC) of the high-voltage battery, compute a degree of deterioration of the high-voltage battery, control a current generated by the motor/generator so that the SOC of the high-voltage battery coincides with a target SOC, vary the target SOC according to the degree of deterioration of the high-voltage battery, determine whether or not the vehicle is decelerating, and set the target SOC to the low target SOC when the vehicle is not decelerating and to the high target SOC when the vehicle is decelerating.</p> |
