The invention provides an electric power assisted steering method and system and a power steering device thereof. The power steering device comprises an auxiliary mechanism unit; a steering shaft passing through the auxiliary mechanism unit in a first direction; a motor which is connected to the auxiliary mechanism unit in the second direction, an included angle being larger than 0 degree and smaller than 180 degrees is formed between the first direction and the second direction; a control unit including: a logic controller connected to either side of the auxiliary mechanism unit in the axial direction of the steering shaft, the logic controller configured to provide logic control and capable of integrating a torque sensor and a steering angle sensor; and a power controller connected between the auxiliary mechanism unit and the motor, is configured to provide motor control and can be integrated with a motor position sensor, wherein the power controller is physically connected with the logic controller. The flexibility of the electric power steering system is improved.

    本发明提供一种电动转向助力方法、系统及其助力装置,助力装置包括:辅助机构单元;转向轴,沿第一方向穿过所述辅助机构单元;电机,沿第二方向连接于所述辅助机构单元,所述第一方向和所述第二方向形成大于0度且小于180度的夹角;控制单元,包括:逻辑控制器,连接于所述辅助机构单元沿所述转向轴的轴向方向的任一侧,所述逻辑控制器配置成提供逻辑控制,且可集成扭矩传感器和转角传感器;以及功率控制器,连接于所述辅助机构单元与所述电机之间,配置成提供电机控制,且可集成电机位置传感器,所述功率控制器与所述逻辑控制器物理连接。本发明提高电动转向助力系统的灵活性。
