The invention relates to a semitrailer with rear wheels having reversing power and a reversing method. The semitrailer comprises an ECU and a rotation angle sensor capable of measuring the rotation angle of a steering wheel, and a pair of wheels at the rearmost end of the semitrailer are two electric wheels capable of being independently driven; the ECU can calculate the deflection angle of the front wheels in the tractor according to the information of the rotation angle sensor, then calculate the turning radius of the semitrailer when the semitrailer backs towards the side rear portion, further calculate the speed difference value between the two electric wheels and control the two electric wheels to actively walk at different speeds so as to achieve steering reversing.
本公开涉及一种后轮具有倒车动力的半挂车辆及倒车方法,包括ECU以及能够测量方向盘转角的转角传感器,半挂车最后端的一对车轮为两个能独立驱动的电动轮;ECU能够根据转角传感器的信息计算出牵引车中前轮的偏角,进而计算出半挂车朝侧后方倒车时的转弯半径,进一步测算出两个电动轮之间的速度差值,并控制两个电动轮以不同速度主动行走,以实现转向倒车。
