The invention discloses a vehicle. The vehicle includes: an electrical load; a generator; a battery; and a controller configured to control an operation of the generator based on a charging rate of the battery, identify a power generation margin rate representing a ratio of power that can be additionally output by the generator to maximum power that can be output by the generator based on a duty ratio of an input voltage applied to the generator, and reducing power consumption of the electrical load based on a comparison between the power generation margin rate and the target margin. The vehicle is capable of preventing or minimizing a voltage drop phenomenon of a generator by using a power generation margin of the generator.
本发明公开一种车辆,该车辆包括:电气负载;发电机;电池;以及控制器,被配置为基于电池的充电率来控制发电机的操作,基于施加到发电机的输入电压的占空比来识别表示所述发电机能够额外输出的电力与所述发电机能够输出的最大电力的比率的发电裕量率,并且基于发电裕量率与目标裕量之间的比较来减小电气负载的功耗。该车辆能够通过利用发电机的发电裕量来防止或最小化发电机的电压下降现象。
