PROBLEM TO BE SOLVED: To efficiently recover regenerative energy by charging a battery, causing the upper limit value of the remaining capacity of the battery to approach full charging, only when deterioration of the battery is in an unpromoted state. SOLUTION: A charge discharge control part 92 informs an assist/ regeneration control part 42 that regeneration is permitted in a range which does not exceed the upper limit value of the quantity of regeneration control, and issues a direction for performing assist/regeneration. The controlling part 42 finds a quantity of assists or regeneration referring to an assist/regeneration map 41 and controls a motor by an assisting quantity if the state of a car is in an assisting region. Regeneration is performed to limit the quantity of regeneration, when the quantity of regeneration exceeds an upper limit value of the quantity of regeneration control informed by the control part 92, regenerating the quantity of regeneration by the motor, if the state of the car is in a regenerating region. Consequently, efficient recovery of regenerative energy without deterioration of a battery becomes feasible. |
