The invention discloses a steering control method for a trailer heavy-duty vehicle. The steering control method comprises the steps that a control instruction of a user is received to determine a current steering mode; the initial steering angle information of the corresponding position is collected through an angle sensor installed on each wheel set; generating an operation instruction according to the target sensing information, the current vehicle speed and all the initial steering angle information; the main controller decomposes the operation instruction into sub-commands which can be executed by all components in the steering system; each component in the steering system is responsive to its corresponding sub-command to enable the trayable heavy duty vehicle to travel in accordance with the current steering mode. Each axis steering mechanism of the wheel set is provided with an angle sensor, the angle sensors can sense the steering angle of each axis and upload angle signals to the controller, and the controller sends out control instructions to control the steering proportional valves corresponding to the three axes according to various angle states of the three axes, so that steering of the three axes is achieved. Therefore, the corresponding steering oil cylinders are controlled to act, and various steering modes are achieved.
本发明公开了一种可拖挂重型载运车的转向控制方法,包括:接收用户的控制指令以确定当前转向模式;利用每个轮组上安装的角度传感器采集相应位置的初始转向角信息;根据目标传感信息、当前车速,所有初始转向角信息生成操作指令;主控制器将操作指令分解为能被转向系统中各个部件执行的子命令;转向系统中各个部件响应于与其对应的子命令以使可拖挂重型载运车能按照当前转向模式进行行驶。本发明轮组每轴线转向机构上均布置了角度传感器,角度传感器可以实现感知各轴线的转向角度,上传角度信号到控制器,控制器根据三个轴线各种的角度状态,发出控制指令控制三个轴线对应的转向比例阀,从而控制对应的转向油缸进行动作,实现多种转向模式。
