  • Patent number: 11733702
    Abstract: An unmanned following vehicle includes a controller that controls the unmanned following vehicle to move in parallel with a moving object by following the moving object on a left side or a right side of the moving object. For example, the controller adjusts a moving speed of the unmanned following vehicle according to a Y-axis coordinate difference value, which is a difference value between a position of the moving object and a position of the unmanned following vehicle in a forward direction. The controller also adjusts a steering direction and a steering angle of the unmanned following vehicle according to an X-axis coordinate difference value, which is a difference value between the position of the moving object and the position of the unmanned following vehicle in a lateral direction.
