The invention discloses a steering wheel limiting and road feeling simulation device suitable for a steer-by-wire system and a control method thereof.The steering wheel limiting and road feeling simulation device suitable for the steer-by-wire system comprises a road feeling motor, a steering shaft, a first shell, a rolling bearing, a first nut, a first spring, a stop nut, a second shell, a second nut and a second spring; a modularized designable road feeling is provided for a driver through the road feeling control strategy based on PID feedforward; the steering shaft is directly connected with a steering wheel through a spline, an external thread is arranged at the lower end of the steering shaft, and the external thread arranged at the lower end of the steering shaft is matched with an internal thread on the inner wall of the stop nut, so that rotation of the steering shaft is converted into movement of the stop nut in the axial direction of the steering shaft. Modularized and designable road feel is provided for a driver, so that the driver can feel stable road feel feedback in the driving process, and the driving safety and comfort are improved.
本发明公开了一种适用于线控转向系统的方向盘限位和路感模拟装置及其控制方法,包括路感电机、转向轴、第一壳体、滚动轴承、第一螺母、第一弹簧、止动螺母、第二壳体、第二螺母和第二弹簧,所述路感电机适配有基于PID前馈的路感控制策略,使得通过所述基于PID前馈的路感控制策略为驾驶员提供模块化可设计的路感;所述转向轴通过花键与方向盘互相直接相连,所述转向轴下端开设有外螺纹,且转向轴下端开设的外螺纹与所述止动螺母内壁的内螺纹互相配合,使得将所述转向轴的转动转化为止动螺母沿转向轴轴向的移动。本发明为驾驶员提供模块化、可设计的“路感”,使得驾驶员在行驶过程中能够感受到稳定的路感反馈,从而提高驾驶的安全性和舒适性。
