The invention relates to the technical field of steering systems, in particular to a steering wheel and front wheel corner coupling alignment method for a steer-by-wire system. A method for steering wheel and front wheel corner coupling alignment of a steer-by-wire system includes a steering wheel alignment state machine. Compared with the prior art, the steering wheel and front wheel steering angle coupling alignment method for the steer-by-wire system can solve the problem of how to align and couple again after up-down decoupling of steer-by-wire; according to the method, power-on automatic operation is achieved, manual key activation is not needed, and the flexibility and comfort of the alignment function are improved; after the steering wheels are aligned, abnormal sound generated by large fluctuation of downward torque can be avoided during upper and lower steering coupling.
本发明涉及转向系统技术领域,具体的说是用于线控转向系统的方向盘与前轮转角耦合对齐的方法。一种用于线控转向系统的方向盘与前轮转角耦合对齐的方法,包括方向盘对齐状态机。同现有技术相比,提供一种用于线控转向系统的方向盘与前轮转角耦合对齐的方法,该方法可以解决线控转向在上下解耦后如何重新对齐耦合的问题;该方法上电自动运行,不需要人为按键激活,提升对齐功能灵活性和舒适性;在方向盘对齐完成后上下转向耦合时可以避免下转力矩波动较大而产生的异响。
