The invention discloses a diagnosis method of a shock absorber, a storage medium, a controller and a vehicle. The diagnosis method of the shock absorber comprises the steps that acceleration data of a sprung structure and an unsprung structure of the vehicle are collected at a preset frequency within a preset period; calculating a first damping coefficient of the damper according to the acceleration data of the sprung structure and the acceleration data of the unsprung structure; and determining the failure condition of the shock absorber according to the first shock absorption coefficient of the shock absorber. According to the technical scheme, original acceleration sensors of the sprung structure and the unsprung structure of the vehicle are adopted, the acceleration data of the sprung structure in the preset period and the acceleration data of the unsprung structure in the preset period are obtained, and therefore the acceleration data of the sprung structure in the preset period can be obtained under the condition that no additional sensor is added and the original structure of a shock absorber is modified. The service life evaluation of the shock absorber is realized, and the setting cost of the shock absorber service life evaluation structure is saved.

    一种减震器的诊断方法、存储介质、控制器以及车辆,减震器的诊断方法包括在预设周期内以预设频率对车辆的簧上结构和簧下结构的加速度数据进行采集;根据簧上结构的加速度数据和簧下结构的加速度数据,计算减震器的第一减震系数;根据减震器的第一减震系数,确定减震器的失效情况。本申请技术方案通过采用车辆簧上结构和簧下结构原有的加速度传感器,对簧上结构在预设周期内的加速度数据以及簧下结构在预设周期内的加速度数据进行获取,如此,以在不增加额外传感器和对减震器原有结构进行改造的情况下,实现减震器的寿命评测,节约减震器寿命评测结构的设置成本。
