The charging rate of the battery (2) is set so that the power that can be inputted to the battery (2) becomes lower as the charging rate approaches a predetermined upper limit value, and the power that can be inputted becomes smaller than the sum of the regenerative power and the generated power when the charging rate of the battery (2) reaches the vicinity of the upper limit value due to the regenerative power received from the drive motor (1) and the generated power received from the generator (4). When power generation is requested to be stopped, fuel supply to the engine (3) is stopped and power generation by the generator (4) is stopped, power is supplied from the battery (2) to the generator (4) and the engine (3) is powered, thereby consuming regenerated power, and when the temperature of the catalyst exceeds a predetermined temperature for suppressing deterioration of the catalyst when power generation is requested to be stopped, the power generation is stopped. The supply of fuel to the engine (3) is continued to maintain the output of the engine (3), and then the output of the engine (3) is reduced when the moving average value of the current related to the sum exceeds a predetermined reference value or when the negative electrode potential of the battery (2) is lower than a predetermined reference potential.
电池2的充电率设定为越接近规定的上限值则对于电池2的可输入电力越低,如果因从驱动电机1接受的再生电力和从发电机4接受的发电电力而使得电池2的充电率到达上限值的附近,可输入电力变得小于再生电力和发电电力的总和,则停止向发动机3的燃料供给而使发电机4的发电停止,从电池2对发电机4供给电力而使发动机3进行动力运行运转,由此消耗再生电力,在发电请求停止时催化剂的温度超过用于抑制催化剂的劣化的规定温度的情况下,持续进行向发动机3的燃料供给,由此维持发动机3的输出,然后在该总和涉及的电流的移动平均值超过规定的基准值时、或者电池2的负极电位低于规定的基准电位时使发动机3的输出降低。
