The invention relates to a hybrid driving method for a trailer and the trailer. The method comprises the following steps: (1) monitoring the gradient of a road section where a vehicle is located by an angle sensor mounted on a chassis of the vehicle, and when the gradient exceeds 15 degrees, commanding a tandem hybrid power driving system on the semitrailer to operate by a computer on the vehicle so that the semitrailer is ensured to have driving force required for climbing; (2) monitoring the speed of the tractor through a low-speed radar sensor, monitoring the instantaneous angular speed of wheels through a photoelectric pulse meter installed on a chassis of the tractor, calculating the slippage rate of the wheels through a computer according to the speed measured by the low-speed radar sensor and signals measured by the photoelectric pulse meter, and when the slippage rate exceeds 10%, commanding, by the computer, a tandem type hybrid power driving system on the semitrailer to operate so as to increase the adhesive force of the wheels to the road surface. The trailer is provided with a corresponding structure capable of implementing the method. The problems that a trailer is insufficient in driving force and poor in power performance can be solved.

    本发明涉及一种用于挂车的混合驱动方法及挂车,该方法包括:(1)由安装在车辆底盘的角度传感器监测车辆所处路段的坡度,当坡度超过15°时,由车辆上的计算机命令半挂车上的串联式混合动力驱动系统运行,以确保半挂车具有爬坡需要的驱动力;(2)由低速雷达传感器对于牵引车的车速进行监测,由牵引车底盘上安装的光电脉冲计监测车轮的瞬时角速度,计算机根据低速雷达传感器测得的车速和光电脉冲计测得的信号计算得出车轮的打滑滑转率,当打滑滑转率超过10%,则由计算机命令半挂车上的串联式混合动力驱动系统运行,以增加车轮对路面的附着力。所述的挂车具有能够实施上述方法的相应结构。本发明可以改善挂车驱动力不足、动力性能差的问题。
