Fault tree-based diagnosis method and device, electronic equipment and storage medium

The invention relates to the technical field of vehicles, and discloses a diagnosis method and device based on a fault tree, electronic equipment and a storage medium, and the method comprises the steps: carrying out the matching operation of vehicle condition information at the current moment and preset vehicle condition information corresponding to a target fault tree if a vehicle fault at the current moment is detected; wherein the vehicle corresponds to the target fault tree; if the matching is successful, diagnosing the fault of the vehicle at the current moment according to a target fault tree to obtain a target fault; outputting a diagnosis report corresponding to the target fault; wherein the diagnosis report comprises the processing strategy and the target fault tree after marking processing, and the target fault tree after marking processing is marked with a target fault event corresponding to the target fault. Diagnosis errors caused by the fact that the target fault tree is used due to the fact th
