PROBLEM TO BE SOLVED: To make a maximum use of the charging capacity of a battery, and to drive a motor with a good energy efficiency by charging the battery with regenerative power generated by the motor, so that a charged quantity may be a target value determined by a target state-of-charging determining means. SOLUTION: When a battery 11 is charged by regenerative power generated by a hybrid motor 2, a target state-of-charging (target SOC) is changed and determined only by a hybrid motor electronic control unit(ECU) 10. Besides, as for regenerative power of wheel motors 7, 8, a target SOC is changed and determined by the hybrid motor ECU 10 and a wheel motor ECU 13. Namely, the hybrid motor ECU 10 and the wheel motor ECU 13 function as a target state-of-charging determining means. Consequently, it becomes possible to make the most efficient use of the charging capacity of the battery, and to consume and recover power with a good energy efficiency. |
