本发明公开了一种线控转向控制系统、控制方法及其车辆,属于车辆技术领域,其中线控转向控制系统,包括转向执行器和路感模拟器,路感控制器通过路感电机进行路感模拟,能够给予驾驶员路感反馈;转向控制器接收转角请求并控制执行电机进行转向,当转向执行器的齿轮转动到机械限位位置时,转向控制器对执行电机的输出扭矩进行控制,避免与机械限位位置发生过大机械干涉;同时路感模拟器同步控制路感电机的输出扭矩,对路感模拟器通过路感电机进行限位,达到限制方向盘转角的目的,这样能够使转向执行器和路感模拟器的转角状态一致,以保证二者的位置对应关系,有效减小出现限位位置关系不对应而导致保护失效的可能性。
The invention discloses a steer-by-wire control system, a control method and a vehicle, and belongs to the technical field of vehicles, the steer-by-wire control system comprises a steering actuator and a road feeling simulator, and the road feeling controller performs road feeling simulation through a road feeling motor and can provide road feeling feedback to a driver; the steering controller receives the steering angle request and controls the execution motor to steer, when a gear of the steering actuator rotates to a mechanical limiting position, the steering controller controls the output torque of the execution motor, and excessive mechanical interference with the mechanical limiting position is avoided; meanwhile, the road feeling simulator synchronously controls the output torque of the road feeling motor, the road feeling simulator is limited through the road feeling motor, and the purpose of limiting the steering angle of the steering wheel is achieved, so that the steering actuator and the road feeling simulator are consistent in steering angle state, and the position corresponding relation of the steering actuator and the road feeling simulator is guaranteed; and the possibility of protection failure caused by non-corresponding limiting position relations is effectively reduced.
