The invention discloses a vehicle fuel evaporation system diagnosis method, device and equipment and a storage medium, and belongs to the technical field of vehicle diagnosis. A carbon tank solenoid valve and a carbon tank stop valve of a target vehicle are controlled to diagnose a fuel evaporation system according to a diagnosis entry request sent by a diagnosis instrument, and diagnosis data are collected; fault code information is determined according to the diagnosis data, and the fault code information is fed back through the diagnosis instrument. In this way, the water temperature, the air inlet temperature, the driving working condition, the fuel oil liquid level and the like of a vehicle engine do not need to meet diagnosis conditions through the triggering mode of the external diagnostic instrument, and the problem processing waiting time is saved. In the diagnosis process, the data flow and the diagnosis result are directly fed back to the diagnosis instrument in real time, visualization of data in the diagnosis process is achieved, the accuracy of problem point detection is improved, and the problem processing efficiency is greatly improved.

    本发明公开了一种车辆燃油蒸发系统诊断方法、装置、设备及存储介质,属于车辆诊断技术领域。本发明通过根据诊断仪发送的诊断进入请求控制目标车辆的碳罐电磁阀与碳罐截止阀进行燃油蒸发系统的诊断,并采集诊断数据;根据所述诊断数据确定故障码信息,并将所述故障码信息通过所述诊断仪反馈。通过这种方式,实现了通过外接诊断仪触发的方式不用需要车辆发动机水温、进气温度、行车工况、燃油液位等满足诊断条件,节省问题处理等待时间。诊断过程中直接将数据流实时及诊断结果反馈到诊断仪,实现诊断过程数据的可视化,提升了问题点检测的准确性,极大提升问题处理效率。
