The invention discloses a steer-by-wire system based on an articulated steering tractor, the steer-by-wire system comprises a steering wheel assembly, an ECU unit and a steering execution assembly which are connected in sequence, and the invention further discloses a control method of the steer-by-wire system of the articulated steering tractor. An ideal front wheel rotation angle is calculated through a control strategy of a fixed angle transmission ratio, meanwhile, an actual front wheel rotation angle is detected through an angle sensor, and the ideal front wheel rotation angle and the actual front wheel rotation angle form deviation to control a steering motor. On the basis of the articulated steering tractor, the steering-by-wire system is used for accurately controlling the steering angle of the front wheel, the turning radius of the articulated steering tractor is further optimized, agricultural operation is more flexible and efficient, the application performance of the articulated steering tractor in the agricultural field is greatly improved, and the market competitiveness of the articulated steering tractor is remarkably enhanced.

    本发明公开了一种基于折腰转向拖拉机的线控转向系统,包括依次连接的转向盘总成、ECU单元和转向执行总成三部分,本发明还公开了折腰转向拖拉机线控转向系统的控制方法,首先利用转角传感器检测转向盘转角,通过固定角传动比的控制策略计算理想前轮转角,同时利用角传感器检测实际前轮转角,理想前轮转角与实际前轮转角构成偏差对转向电机进行控制。本发明基于折腰转向拖拉机,通过线控转向系统对前轮转角进行精确控制,进一步优化了其转弯半径,实现了农业作业的更加灵活高效,大幅提升了折腰转向拖拉机在农业领域的应用性能,显著增强了其市场竞争力。
