The invention belongs to the technical field of automobiles, and particularly provides a steer-by-wire system for an automobile and the automobile. The invention aims to solve the problem that the signal of the sensor is repeated when the steering angle of the steering wheel of the existing steer-by-wire system exceeds 360 degrees. Therefore, the steer-by-wire system comprises a force feedback motor, a rotating shaft, a transmission part and a displacement sensor. The force feedback motor comprises an inner stator and an outer rotor, and the inner stator is used for being connected with an automobile body of the automobile. The rotating shaft and the outer rotor are fixedly connected or integrally manufactured, and the rotating shaft and/or the outer rotor are/is used for being connected with a steering wheel. The transmission part is in sliding connection with the inner stator, and the transmission part is in driving connection with the rotating shaft, so that the transmission part converts the rotating motion of the rotating shaft into linear motion under the limitation of the inner stator. The displacement sensor is used for detecting the linear displacement of the transmission part. The technical problems are solved.

    本发明属于汽车技术领域,具体提供了一种用于汽车的线控转向系统和汽车。本发明旨在解决现有的线控转向系统在方向盘的转角超过360°时,传感器的信号会出现重复的问题。为此,本发明的线控转向系统包括力反馈电机、转轴、传动件和位移传感器。其中,力反馈电机包括内定子和外转子,所述内定子用于连接所述汽车的车身。转轴与所述外转子固定连接或一体制成,所述转轴和/或所述外转子用于连接方向盘。传动件与所述内定子滑动连接,所述传动件与所述转轴驱动连接,以使所述传动件在所述内定子的限制下将所述转轴的旋转运动转换为线性移动。位移传感器用于检测所述传动件的线性位移。本发明克服了上述技术问题。
