The invention discloses an electric power steering system which comprises a torque and angle sensor, a controller, an axial flux motor, an input shaft, a torsion bar and an output shaft, the input shaft, the torsion bar, a motor shaft of the axial flux motor and the output shaft are located on the same axis, one part of the torque and angle sensor is connected with the input shaft, and the other part of the torque and angle sensor is connected with the torsion bar. The input shaft is connected with the motor shaft through a torsion bar, the end, away from the motor shaft, of the input shaft is connected with the steering wheel, the end, away from the input shaft, of the motor shaft is connected with the output shaft, the controller is in communication connection with the torque and angle sensor, and the controller is electrically connected with the axial magnetizer. The invention further discloses an automobile. By using the axial magnetic flux motor, the problems of abnormal sound, fluctuation, efficiency loss and the like caused by existence of a turbine speed reducing mechanism are avoided, the controller, the motor and the sensor in the electric power steering system are highly integrated, and the size of the system structure is reduced.

    本发明公开了一种电动助力转向系统,其包括:扭矩和角度传感器、控制器、轴向磁通电机、输入轴、扭力杆和输出轴,输入轴、扭力杆、轴向磁通电机的电机轴和输出轴位于同一轴线上,扭矩和角度传感器一部分与输入轴连接,扭矩和角度传感器的另一部分与电机轴连接,输入轴与电机轴通过扭力杆连接,输入轴远离电机轴的一端与方向盘连接,电机轴远离输入轴的一端与输出轴连接,控制器与扭矩和角度传感器通讯连接,控制器与轴向磁通电机电性连接。本发明还公开了一种汽车。本发明通过使用轴向磁通电机,避免了涡轮减速机构的存在而导致的异响、波动和效率损失等问题,使电动助力转向系统中控制器、电机和传感器高度高集成度,减少系统结构的尺寸。
