摘要： PROBLEM TO BE SOLVED: To prevent electrostatic charge capacity from decreasing due to memory effect, in a hybrid type electrically-driven vehicle equipped with a generator which generates power by being driven by an engine, a storage device which stores electric energy generated by the generator and an electric motor, in which electric energy is supplied from the storage device. SOLUTION: In completely discharging a storage part A, to prevent decrease in electrostatic charge capacity due to memory effect, if its storage capacity SOCA becomes lower than a predetermined value MC1, subsequent discharging of the storage part A is performed; while since a storage capacity SOCB of the other storage part B is maintained so as to be higher a predetermined value 2, the storage device is no longer need to be discharged completely, and such a situation as a vehicle becoming difficult to drive is avoided.

摘要： PROBLEM TO BE SOLVED: To efficiently charge a battery on a vehicle when the SOC of the battery is lowered. SOLUTION: An engine 1 is coupled through a torque converter T/C2 to a motor generator M/G3 coupled to an automatic transmission A/T4. If the SOC(state of charge) of a battery 41 is lowered, the output power of the engine 1 is increased so as to allow the motor generator M/G3 to serve as a generator for generating power. The rotational frequency and the torque of the engine 1, the slip rate of the torque converter T/C2, and the rotational frequency and the torque of the motor generator M/G3 are controlled by an ECU 100 in order to obtain a maximum power generation efficiency.
