Open systems and the corresponding interfaces for automotive electronics (OSEK) architecture-based automobile fault diagnosis method and device, automobile and storage medium

Abstract

The invention relates to an open systems and the corresponding interfaces for automotive electronics (OSEK) architecture-based automobile fault diagnosis method and device, an automobile and a storagemedium. The automobile fault diagnosis method comprises the following steps of acquiring each vehicle real-time state information of a vehicle; comparing the acquired vehicle real-time state information with preset vehicle fault state information, and judging whether the vehicle real-time state information is vehicle fault state information or not, wherein the preset vehicle fault state information comprises advance fault state information and conventional fault state information, the step of judging whether the vehicle real-time state information is the vehicle fault state information or notcomprises the step of judging and identifying that the vehicle real-time state information is the advanced fault state information or the conventional fault state information; and preferably processing the advance fault state information when the vehicle real-time state information is judged and identified to be the advance fault state information. During the fault diagnosis process, various faults can be classified and processed according to priority, and an import fault is conveniently and timely found out and processed.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to an OSEK architecture-based vehicle fault diagnosis method, device, vehicle and storage medium. Background technique [0002] At present, the fault diagnosis system of electric vehicles is generally developed based on the software architecture and system of OSEK (open systems and the corresponding interfaces for automotive electronics, which refers to the German automotive electronics open system and corresponding interface standards). However, in the traditional technology, the electric vehicle diagnosis system generally obtains the operating state characteristics of the electric vehicle through the network, compares and evaluates it with the fault feature database in real time, and determines whether there is a fault. In this technical scheme, when a BUS-OFF (bus-off) fault occurs, all nodes will fail; all faults will be recorded and sent to the fault diagnosis...

AI Technical Summary

Problems solved by technology

In this technical scheme, when a BUS-OFF (bus-off) fault occurs, all nodes will fail; all faults will be recorded and sent to the fault diagnosis system for processing. When there are many faults in the vehicle, major faults cannot be To detect and deal with it in time; when reading the fault memory, there may be too many recorded faults and it is impossible to record all faults; when multiple control systems are involved, more than one diagnostic or diagnostic redundant system is required to ensure the safety of the vehicle; for Different models need to develop different diagnostic modules, which has certain limitations
