The invention discloses a method for suppressing a steering wheel from swinging in a hand disengaging state of a driver. The method comprises the following steps: calculating the torque and angle vector value of torsion bar deformation; and calculating a required assistance vector value and a suppression force vector value signal. A steering master control unit calculates a final assistance value vector according to the received assistance vector value signal and the suppression force vector signal, and outputs the final assistance value vector signal to a motor; and the motor executes the final power-assisted vector value outputted by the steering master control unit to perform power-assisted suppression on swing of the steering wheel. According to the method for suppressing the steering wheel from swinging in the hand disengaging state of the driver, the steering swinging suppressing control module is additionally arranged on the basis of a steering common power assisting module, the steering swinging suppressing control module only acts in the hand disengaging state of the driver, suppressing force vector values can be provided, and the steering wheel can be suppressed from swinging in the hand disengaging state of the driver; the stability of the automobile steering wheel is improved, and the driving safety is guaranteed.

    本发明公开了一种驾驶员脱手状态下抑制方向盘摆动的方法,包括如下步骤:计算扭杆变形的扭矩和角度矢量值;计算所需要的助力矢量值和抑制力矢量值信号。转向总控制单元根据所接收的助力矢量值信号和抑制力矢量信号计算最终助力值矢量,并将最终助力值矢量信号输出至电机;电机执行转向总控制单元所输出的最终助力矢量值,进行助力抑制方向盘摆动。本发明所涉及的一种驾驶员脱手状态下抑制方向盘摆动的方法,在转向普通助力模块的基础上增加了转向抑制摆动控制模块,此模块仅在驾驶员脱手状态下作用,可以提供抑制力矢量值,能够在驾驶员脱手状态下抑制方向盘摆动,增加了汽车方向盘的稳定性,保障了行车安全。
