The invention relates to the technical field of vehicle steering devices, and provides a steer-by-wire hand feeling simulator, a vehicle and a steering wheel resistance control method. The steer-by-wire hand feeling simulator comprises a shell, a connecting shaft and a control circuit. A containing cavity is formed in the shell, the containing cavity is filled with magnetorheological fluid, and a limiting structure is arranged in the containing cavity; one end of the connecting shaft is used for being connected with a steering wheel, the other end of the connecting shaft is arranged in the containing cavity, fan blades are arranged at the end, in the containing cavity, of the connecting shaft, and the connecting shaft can rotate to drive the fan blades to stir the magnetorheological fluid; the control circuit can control the resistance of the magnetorheological fluid to the rotation of the fan blades, and the magnetorheological fluid is matched with the limiting structure when solidified so as to limit the rotation of the fan blades relative to the shell. Through mutual cooperation of the control circuit, the connecting shaft, the magnetorheological fluid and the limiting structure, the steer-by-wire hand feeling simulator can conveniently change the rotation resistance of a steering wheel to simulate the hand feeling, the number of rotation turns of the steering wheel can be limited, the structure of a vehicle steering system is simplified, and the assembly efficiency is improved.
本申请涉及车辆转向装置技术领域,提供一种线控转向手感模拟器、车辆及方向盘阻力控制方法。其中线控转向手感模拟器包括壳体、连接轴和控制电路;壳体的内部设有容纳腔,容纳腔内填充有磁流变液,且容纳腔内设有限位结构;连接轴的一端用于与方向盘连接,另一端置于容纳腔内,且连接轴在容纳腔内的一端设有扇叶,连接轴能转动以带动扇叶搅动磁流变液;控制电路能控制磁流变液对扇叶转动的阻力,且磁流变液固化时与限位结构配合,以限制扇叶相对壳体转动。通过控制电路、连接轴、磁流变液和限位结构的相互配合,使线控转向手感模拟器既能便捷的改变方向盘转动阻力以模拟手感,又能限制方向盘转动圈数,简化了车辆转向系统的结构,提升装配效率。
