The invention discloses a dual-winding dual-motor steer-by-wire system of a commercial vehicle and a control method of the dual-winding dual-motor steer-by-wire system. The dual-winding dual-motor steer-by-wire system comprises a steering wheel module, a dual-winding dual-motor power assisting module, a circulating ball hydraulic power assisting module, a mechanical transmission module and a steering control unit. The system has a motor and winding dual hardware redundancy function, the failure of steering instruction execution caused by faults of any single steering motor or single winding is avoided, the reliability of a steer-by-wire system is further improved, and the safety of a vehicle is enhanced; in addition, the advantages of a double-winding motor are integrated, compared with a single-winding motor, larger torque can be output, the torque requirement needed by an existing commercial vehicle steer-by-wire system is met, and the problems that energy consumption is large and the response speed is low are solved.
本发明公开了一种商用车双绕组双电机线控转向系统及其控制方法,包括:转向盘模块、双绕组双电机助力模块、循环球液压助力模块、机械传动模块及转向控制单元;本发明具有电机、绕组双重硬件冗余功能,避免了任何一个单转向电机或者单个绕组故障而造成转向指令执行的失效,进一步提高了线控转向系统的可靠性,增强了车辆安全性;此外,融合了双绕组电机的优点,相比单绕组电机能够输出更大的转矩,保证了现有商用车线控转向系统所需的转矩要求,解决了能耗较大且响应速度慢的问题。
