The invention relates to a steering column assembly abnormal sound detection method and device, a vehicle and a storage medium, and belongs to the technical field of vehicles, and the method comprises the steps that a first acceleration signal set sent by a plurality of acceleration sensors arranged on a plurality of parts of a steering column assembly is received; performing filtering processing on the first acceleration signal set, and judging whether crest values of all acceleration signals in the first acceleration signal set are smaller than a first calibration threshold value or not; when the crest value of any acceleration signal is larger than or equal to a first calibration threshold value and abnormity is not recorded in the ignition cycle, the abnormity is recorded once; and sending an abnormal sound reminding signal under the condition that the abnormal continuous recording frequency exceeds a preset frequency. According to the embodiment of the invention, the acceleration signal on the steering column assembly is collected in real time, so that the daily vehicle use scene of a driver can be completely covered, the abnormal sound condition is considered to occur only when the abnormal continuous recording times exceed the preset times, and misjudgment caused by a special road scene is avoided.
本发明涉及一种转向柱总成异响检测的方法、装置、车辆和存储介质,属于车辆技术领域,包括:接收设置在转向柱总成的多个部件上的多个加速度传感器发送的第一加速度信号集合;对第一加速度信号集合进行滤波处理,判断第一加速度信号集合中所有加速度信号的波峰值是否小于第一标定阈值;在任一加速度信号的所述波峰值大于等于第一标定阈值,且本次点火循环内未记录异常的情况下,记录一次异常;在异常连续记录次数超过预设次数的情况下,发送异响提醒信号。本发明实施例通过实时采集转向柱总成上加速度信号,可以完全覆盖驾驶员日常用车场景,在异常连续记录次数超过预设次数的情况下,才认为出现异响情况,避免因为特殊路面场景引起误判。
