The invention provides a dual-mode coupling steer-by-wire system and a steering angle tracking control method thereof. The dual-mode coupling steer-by-wire system comprises a steering motor module, a steering transmission module, a commutator, an electromagnetic clutch, a steering angle sensor and an ECU control module. The commutator comprises a commutator A and a commutator B and is used for changing the output torque direction of the steering motor module; the electromagnetic clutch is used for connecting the commutator A and the commutator B to realize power disconnection or connection between the commutator A and the commutator B; the rotation angle sensor is used for obtaining rotation angles of wheels and transmitting the rotation angles to the ECU control module; the ECU control module is connected with the steering angle sensor, the steering motor A driver and the steering motor B driver and used for controlling the electromagnetic clutch, the steering motor A driver and the steering motor B driver to work according to induction signals of the steering angle sensor. According to the system, the steering flexibility and the structural reliability of the steer-by-wire system are improved.

    本发明提供一种双模耦合线控转向系统及其转角跟踪控制方法。双模耦合线控转向系统包括:转向电机模块,转向传动模块,换向器,电磁离合器,转角传感器,ECU控制模块;换向器包括换向器A和换向器B,用于改变转向电机模块的输出扭矩方向;电磁离合器用于连接换向器A和换向器B,实现换向器A和换向器B之间的动力断开或连接;转角传感器用于获得车轮的转角,并将其传递给ECU控制模块;ECU控制模块分别和转角传感器、转向电机A驱动器及转向电机B驱动器相连,用于根据转角传感器的感应信号控制电磁离合器、转向电机A驱动器和转向电机B驱动器工作。本发明的系统提高了线控转向系统的转向灵活性和结构可靠性。
