The invention provides a commercial vehicle electric control power-assisted steering system and a control method. The commercial vehicle electric control power-assisted steering system is characterized in that an upper steering column is connected with a steering wheel; the electromagnetic clutch is arranged between the upper steering column and the lower steering column and used for controlling mechanical connection and decoupling between the upper steering column and the lower steering column; the aligning and road feeling motor is mounted on the upper steering column and used for providing steering aligning torque and road feeling feedback; the electro-hydraulic power-assisted steering mechanism is connected with the lower steering column and used for providing power for wheel steering; the steering connecting rod is connected with the electro-hydraulic steering power-assisted mechanism and the wheels and used for transmitting steering torque to the wheels. And the control unit is used for controlling the connection and disconnection of the electromagnetic clutch according to the running state and the driving mode of the vehicle, and controlling the working states of the return and road feeling motor and the electro-hydraulic power-assisted steering mechanism. According to the scheme, the safety and reliability of vehicle driving are improved.

    本发明提供一种商用车电控助力转向系统及控制方法,包括:上转向管柱与方向盘相连;电磁离合器,设置在上转向管柱和下转向管柱之间,用于控制上转向管柱与下转向管柱之间的机械连接与解耦;回正及路感电机,安装在上转向管柱上,用于提供转向回正力矩和路感反馈;电液转向助力机构与下转向管柱相连,用于提供车轮转向的助力;转向连杆与电液转向助力机构和车轮连接,用于传递转向力矩至车轮;控制单元,用于根据车辆行驶状态和驾驶模式控制电磁离合器的接合与分离,以及,控制回正及路感电机和电液转向助力机构的工作状态。本发明的方案,提高了车辆驾驶的安全性和可靠性。
