The invention discloses an automobile electromagnetic power-assisted steering device and a control method. When a driver turns a steering wheel to the left, a direction bevel gear at the lower end of the direction shaft simultaneously drives a transmission bevel gear and a driven bevel gear of a rotation angle sensor to rotate, and a vertical plate in the middle section deflects to the left to press a pressure variable resistor disc of a left pressure sensor; and the computer control instrument adjusts the voltage and the initial phase angle of the sine alternating current of the two groups of coils of the electromagnetic power-assisted rotor according to a signal of the left pressure sensor and a signal of the rotation angle sensor. The front magnetic pole is adjusted from an S-pole magnetic field to a zero magnetic field; the rear magnetic pole is adjusted from an N-pole magnetic field to a zero magnetic field, the left magnetic pole gradually adjusts the N-pole magnetic field from the zero magnetic field, and the right magnetic pole gradually adjusts the S-pole magnetic field from the zero magnetic field. The electromagnetic power-assisted steering gear assists the transmission bevel gear to rotate clockwise, the transmission bevel gear rotates clockwise to drive the rack to move rightwards, the rack moves rightwards to enable the direction control rod to move rightwards, and the direction control rod moves rightwards to enable the two front wheels to deflect leftwards.
本发明公开一种汽车电磁助力转向装置及控制方法。当司机把方向盘向左转动,方向轴方向轴下端的方向锥形齿轮同时带动传动锥形齿轮和转动角度传感器的被动锥形齿轮转动,中段的竖版向左偏转压动左压力传感器的压变电阻片,电脑控制仪根据左压力传感器的信号和转动角度传感器的信号调整电磁助力转器两组线圈的正弦交流电的电压和初相角。前磁极由S极磁场向零磁场调整;后磁极由N极磁场向零磁场调整,左磁极由零磁场逐渐调整N极磁场,右磁极由零磁场逐渐调整S极磁场。电磁助力转向器帮助传动锥形齿轮顺时针转动,传动锥形齿轮顺时针转动带动齿条向右移动,齿条向右移动使方向操纵杆向右移动,方向操纵杆向右移动使两个前边的车轮向左偏转。
