Transient fault processing method and system of vehicle bus control system and vehicle

Abstract

The invention discloses a transient fault processing method and system of a vehicle bus control system and further discloses a vehicle provided with the processing system. The processing method provided by the invention comprises the steps of: S1, node-level fault processing; and S2, system-level fault processing. A hierarchical processing method is adopted for processing the transient fault of the vehicle bus control system, on the one hand, the transient fault can be processed and responded rapidly to improve the fault elimination efficiency, and on the other hand, superior resources in the system can be used for eliminating a small number of difficult faults in a centralized manner so as to facilitate the reasonable utilization of the resources of the vehicle bus control system. The processing system provided by the invention comprises at least one electronic control unit and a central controller, wherein the electronic control unit is used for processing node-level faults and reporting the node-level faults which cannot be processed to the central controller, and the central controller is used for processing system-level faults. The processing system disclosed by the invention has the advantage of improving the fault elimination efficiency and effectively utilizing the resources of the bus control system.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a bracket device and a vehicle equipped with the bracket device. Background technique [0002] With the development of electronic control technology, vehicle bus network communication technology has been widely used in the field of vehicles. At the same time, it has also brought about the increasingly prominent problem of instantaneous failure of the vehicle bus control system. The vehicle bus control system is a relatively complex control system. If the instantaneous fault in the system cannot be solved in time and effectively, it will seriously threaten people's property safety and personal safety. [0003] The operating environment of vehicles, especially engineering vehicles, is complex and changeable, and both external and internal disturbances may cause instantaneous failure of the vehicle bus control system. In the vehicle bus control system, system-level faults and f...

AI Technical Summary

Problems solved by technology

At present, due to the lack of consideration of the propagation law of transient faults in the vehicle bus control system and the communication constraints of the system, the centralized controller method is mainly used to solve the fault diagnosis and processing problems of the vehicle bus control system, and the transient faults in the vehicle bus control system cannot be analyzed. Rapid processing response is not conducive to the rational utilization of control system resources
