An unmanned vehicle (20) travels by driving an electric motor using electric power generated by a generator, and is provided with a position sensor (240) for detecting the position of the unmanned vehicle (20), a speed sensor (250) for detecting the speed of the unmanned vehicle (20), and a vehicle control device (220) for controlling the unmanned vehicle (20). On the basis of the position of the unmanned vehicle (20) detected by the position sensor (240) and the speed of the unmanned vehicle (20) detected by the speed sensor (250), the vehicle control device (220) calculates the work progress of the loading work to the unmanned vehicle (20) by the loader (30) or the work progress of the preceding vehicle. The time from the time at which the calculated work progress is predicted to exceed the predetermined proportion to the time at which the unmanned vehicle (20) is predicted to start acceleration is calculated as the acceleration preparation time, and the generator is caused to generate power during the calculated acceleration preparation time.

    无人车辆(20)是通过由发电机发出的电力来驱动电动马达并通过电动马达的驱动而行驶的车辆,具有检测无人车辆(20)的位置的位置传感器(240)、检测无人车辆(20)的速度的速度传感器(250)和控制无人车辆(20)的车辆控制装置(220)。车辆控制装置(220)基于由位置传感器(240)检测到的无人车辆(20)的位置和由速度传感器(250)检测到的无人车辆(20)的速度来计算基于装载机(30)执行的向无人车辆(20)的装载作业的作业进度或前行车辆的作业进度,并作为加速准备时间而计算从预测为计算出的作业进度超过规定比例的时刻到预测为无人车辆(20)开始加速的时刻为止的时间,在计算出的加速准备时间的期间内使发电机发电。
