The invention relates to a commercial vehicle steering column reset system with a memory function. The hardware part of the commercial vehicle steering column reset system comprises a main control unit, a key circuit, a driving circuit, a power switching circuit, an overcurrent and overvoltage protection circuit and direct-current motors, wherein the key circuit comprises four key switches, the four key switches are used for man-machine interaction, every two switches control forward rotation and reverse rotation of one direct-current motor, and the four key switches control forward rotation and reverse rotation of the two direct-current motors respectively, so that up-and-down movement and front-and-back movement of a steering wheel of the vehicle are achieved. According to the invention,forward rotation and reverse rotation of the two direct-current motors are controlled through PWM signal control to control the specific position of a steering column. The commercial vehicle steeringcolumn reset system with the memory function and the control method thereof have the advantages that the response is rapid, the control operation steps are simple, and the application is convenient.
本发明涉及的一种带记忆功能的商用车转向管柱复位系统,它的硬件部分包括主控单元、按键电路、驱动电路、电源转换电路、过流过压保护电路以及直流电机;按键电路包括四个按键开关,使用四个按键开关负责人机交互,每两个开关控制一个直流电机的正转和反转,四个按键开关分别控制两个直流电机的正反转,从而实现车辆方向盘上下与前后移动。本发明通过PWM信号控制来控制两个直流电机的正反转来控制转向管柱的具体位置,带记忆功能的商用车转向管柱复位系统及其控制方法具有响应较快,控制操作步骤较为简单,应用方便的优点。
