The invention discloses a steering-by-wire active return method based on a return rotating speed reference model, and relates to the field of automobile steering wheel active return. Acquiring a return intention of the driver according to an active return state judgment mechanism based on a time window; obtaining a target steering wheel aligning rotating speed according to the aligning rotating speed reference model and the current steering wheel rotating angle; acquiring required active aligning torque according to the current rotating speed of the steering wheel and the target aligning rotating speed by using a control method; and based on the active aligning torque transition mechanism, obtaining the final active aligning torque requested from the road sensing motor. According to the method, the return rotating speed reference model is designed based on the steering-by-wire system dynamics model, so that the smooth steering wheel return process is achieved, driving scenes of low, medium and high vehicle speeds are covered, and the comfort experience of a driver for steering wheel return is enhanced.

    本发明公开了一种基于回正转速参考模型的线控转向主动回正方法,涉及汽车转向盘主动回正领域,该方法包括:获取相关车辆参数;根据基于时间窗的主动回正状态判断机制获取驾驶员的回正意图;根据回正转速参考模型和当前的转向盘转角获取目标转向盘回正转速;利用控制方法根据当前转向盘转速和目标回正转速获取需求的主动回正力矩;基于主动回正力矩过渡机制,得到最终的向路感电机请求的主动回正力矩。本发明基于线控转向系统动力学模型设计了回正转速参考模型,以实现平顺的转向盘回正过程,覆盖低、中、高各车速的行驶场景,增强了驾驶员对于转向盘回正的舒适性体验。
