The invention provides a vehicle shock absorber fault detection method, a controller and a vehicle. The method comprises the following steps: acquiring a plurality of vertical acceleration time domain signals of the vehicle; determining a power spectral density curve of the vertical acceleration based on the plurality of vertical acceleration time domain signals; determining a region area corresponding to a target frequency band in the power spectral density curve; according to the area of the area and the current temperature of the vehicle shock absorber, fault detection is conducted on the vehicle shock absorber, and a fault detection result is obtained; therefore, in the running process of the vehicle, the vertical acceleration signal of the vehicle is collected in real time for power spectrum analysis, and the power spectrum density can reflect the energy distribution of the shock absorber, so that when the shock absorber breaks down, the fault can be accurately detected based on the power spectrum density curve; therefore, the running stability and the running safety of the vehicle are improved.

    本发明提供了一种车辆减振器故障检测方法、控制器及车辆,方法包括:获取车辆的多个垂向加速度时域信号;基于所述多个垂向加速度时域信号,确定所述垂向加速度的功率谱密度曲线;确定所述功率谱密度曲线中目标频段对应的区域面积;根据区域面积和车辆减振器的当前温度,对车辆减振器进行故障检测,得到故障检测结果;如此,在车辆行驶过程中,实时采集车辆的垂向加速度信号进行功率谱分析,由于功率谱密度可反应出减振器的能量分布,因此当减振器出现故障时,可基于功率谱密度曲线准确检测出故障,从而提高车辆运行的稳定性以及车辆运行的安全性。
