An embodiment of the invention provides a redundant electric power steering device. The redundant electric power steering device includes a first circuit board and a second circuit board configured to control a motor; the first circuit board and the second circuit board are arranged in a stacked mode in the direction parallel to the end surface of a motor shell; a plurality of control units are arranged on the first circuit board; the second circuit board comprises a plurality of redundant parts; the plurality of redundant parts are positioned on the same plane; and each redundant part is connected with the first circuit board in a bending manner. According to the redundant electric power steering device, the occupied space of a circuit board and part composition in the redundant electric power steering device are reduced, the arrangement efficiency in packaging is improved, the packaging size is reduced, the space utilization rate is improved, and the limitation of the installation space in a vehicle is overcome.

    本发明实施例提供了一种冗余电动助力转向装置,该冗余电动助力转向装置包括:被配置为控制电机的第一电路板和第二电路板;其中,第一电路板、第二电路板沿平行于电机的机壳端面的方向层叠设置;第一电路板上设置有多个控制单元;第二电路板包括多个冗余部分;多个冗余部分位于同一平面上;每个冗余部分分别与第一电路板弯折连接。该冗余电动助力转向装置减少了冗余电动助力转向装置中电路板的占用空间及零件组成,有利于提高封装中的布置效率,减小封装的尺寸,提高了空间利用率,有利于克服车辆内安装空间的限制。
