The invention relates to a diagnostic
event management method, device and equipment, a medium and a vehicle. The method comprises the following steps: when a diagnosis event is reported, collecting and caching a freezing frame of the diagnosis event; collecting extended data of the diagnosis event, and de-jittering the diagnosis event to obtain a de-jittering result; if the de-
jitter result represents that the diagnosis event is a fault phenomenon, performing nonvolatile storage on the frozen frame and the extended data as diagnosis data of the diagnosis event; and if the
jitter removal result represents that the diagnosis event is a random phenomenon, deleting the frozen frame and the extended data. According to the invention, when the diagnosis event is reported, the frozen frame of the diagnosis event is collected immediately, so that the vehicle
system operation state recorded by the frozen frame is extremely small in change relative to the vehicle
system operation state when the diagnosis event occurs; therefore, the collected freezing frame more accurately records the running state of the vehicle
system when the diagnosis event occurs, and has higher practical value.
