The invention provides a trailer width projection method. The method comprises the steps that trailer driving state information is determined based on driving state data of a tractor; determining a projection mode based on the width of the trailer and the trailer driving state information; and controlling projection equipment mounted at the tail of the trailer to execute tail width projection suitable for indicating the width of the trailer on the ground behind the trailer based on the determined projection mode. According to some embodiments of the invention, dynamic width projection is performed behind the tail part of the trailer based on the width and the driving state of the trailer, especially the driving track, so that users on other surrounding roads can be prompted timely and properly according to the driving state, and the users can pay attention to the width and the driving track of the trailer; and a safe distance and a safe driving state are kept, so that potential collision risks are avoided. The invention further provides a corresponding trailer width projection system, a trailer with the trailer width projection system and a vehicle with the trailer.

    本发明提出了一种挂车示宽投影方法,包括:基于牵引车的行驶状态数据确定挂车行驶状态信息;基于所述挂车的宽度和所述挂车行驶状态信息确定投影模式;和基于确定的所述投影模式控制安装于所述挂车的尾部的投影设备在所述挂车后方地面上执行适于指示所述挂车的宽度的车尾示宽投影。根据本发明的一些实施例,通过基于挂车的宽度和行驶状态、特别是行驶轨迹在挂车尾部后方进行动态的示宽投影,能够根据行驶状况及时且适当地对周围其他道路使用者进行提示,使其关注挂车的宽度和行驶轨迹,保持安全距离和安全行驶状态,以避免潜在的碰撞风险。本发明还提出了相应的挂车示宽投影系统、具有所述挂车示宽投影系统的挂车和具有所述挂车的车辆。
