The invention provides a method and system for restraining axial shaking of a steering wheel, a storage medium and equipment, and the method comprises the steps: obtaining vehicle information, and obtaining a wheel vibration frequency through a preset formula according to the vehicle information; a sensor arranged on the vehicle is controlled to collect real-time torque information on a steering wheel, and spectral analysis is conducted on the real-time torque information; filtering a spectral analysis result through a preset method to obtain a corrected torque vibration amplitude and a corrected torque vibration frequency; comparing the corrected torque vibration frequency with the wheel vibration frequency, and judging whether the ratio of the corrected torque vibration frequency to the wheel vibration frequency is within a preset range or not; if yes, a counter torque control signal is sent to the automobile power-assisted steering system according to the corrected torque vibration frequency and the corrected torque vibration amplitude, so that the automobile power-assisted steering system suppresses axial shaking of a steering wheel. The problem that in the prior art, the wheel dynamic balance of a vehicle is poor, a steering wheel shakes, and then the driving experience of a driver is affected is solved.
本发明提供一种抑制方向盘轴向抖动的方法、系统、存储介质及设备,所述方法包括:获取车辆信息,并根据车辆信息通过预设公式得到车轮振动频率;控制布设于车辆上的传感器采集方向盘上实时扭矩信息,并对实时扭矩信息进行频谱分析;将频谱分析的结果通过预设方法进行过滤,得到修正扭矩振动幅值和修正扭矩振动频率;将修正扭矩振动频率与车轮振动频率进行比较,并判断两者的比值是否在预设范围内;若是,则根据修正扭矩振动频率和修正扭矩振动幅值向汽车助力转向系统发出反力矩控制信号,以使汽车助力转向系统抑制方向盘轴向抖动。本发明解决了现有技术中的车辆的车轮动平衡较差,使得方向盘抖动进而影响驾驶员的驾驶体验的问题。
