The invention discloses a vehicle fault identification method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining a count value obtained by monitoring the desorption flow of the vehicle through an air flow meter; load desorption working conditions of the vehicle are determined, the load desorption working conditions comprise the first load desorption working condition and the second load desorption working condition, and the first load desorption working condition and the second load desorption working condition are determined according to the comparison result of the first pressure value of the intake manifold and the second pressure value of the atmospheric environment; and determining whether the desorption flow has a fault according to the load desorption working condition and the count value. According to the method and the device, the technical problem that the running stability of the vehicle is influenced due to the fact that the desorption flow is determined through a fully-opened and fully-closed carbon canister electromagnetic valve in the prior art is solved.

    本发明公开了一种车辆故障的识别方法、装置、车辆及存储介质,其中,车辆故障的识别方法包括:获取空气流量计对车辆的脱附流量进行监测得到的计数值;确定车辆的负荷脱附工况,其中,负荷脱附工况包括第一负荷脱附工况和第二负荷脱附工况,第一负荷脱附工况与第二负荷脱附工况由进气歧管的第一压力值与大气环境的第二压力值的比较结果来确定;根据负荷脱附工况和计数值确定脱附流量是否存在故障。本发明解决了由于相关技术中通过全开全闭炭罐电磁阀确定脱附流量,从而存在影响车辆行驶的稳定性的技术问题。
