PROBLEM TO BE SOLVED: To prevent a battery from deteriorating without losing regeneration power when the regeneration power is generated from a motor. SOLUTION: When a motor is in regeneration state, maximum regeneration electrical energy is read from a maximum regeneration electrical energy operation part (S160). Then, the electrical energy is controlled so that the sum of the maximum regeneration electrical energy and the amount of electricity generated by a generator reaches an allowable charge electrical energy that is the output of a battery allowable charge power operation part 10. By subtracting the maximum regeneration electrical energy read in the step S160 from the allowable charge electrical energy of the battery, the amount of electricity generated is calculated. Also, the conduction rate of the field current of a generator 2 that matches the amount of electricity generated is calculated (S170). The control of the conduction rate of the field current and a constant speed control for controlling the fluctuation of an end speed due to the fluctuation of the drive torque of the generator to a specific speed are executed simultaneously by a generation unit controller (S180). |
