An SBW steering system and steering wheel reaction torque signal generation method and device thereof. The present disclosure relates to a device and method for generating steering reaction torque. In providing a reaction torque to a steering wheel of a steer-by-wire steering system, the device may determine a target frequency according to the rotational speed of the wheel, generate a filtered rack force signal excluding a cutoff band including the target frequency from the rack force signal, generate a target reaction torque signal based on the filtered rack force signal, and generate the reaction torque based on the target reaction torque signal. Therefore, it is possible to improve the steering feeling of the SBW steering system by providing the steering wheel with reaction torque from which unnecessary vibration components such as shimmy and judder are removed.
SBW转向系统及其方向盘反作用扭矩信号生成方法和装置。本公开涉及用于生成转向反作用扭矩的装置及方法。在向线控转向系统的方向盘提供反作用扭矩时,装置可以根据车轮的转速确定目标频率,生成从齿条力信号中排除了包含目标频率的截止频带的经滤波的齿条力信号,基于经滤波的齿条力信号生成目标反作用扭矩信号,并基于目标反作用扭矩信号生成反作用扭矩。因此,可以通过为方向盘提供从中去除了诸如摆振和颤振之类的不必要振动分量的反作用扭矩,来改善SBW转向系统的转向感。
