Abstract

The invention is suitable for the technical field of vehicle diagnosis and provides a vehicle diagnosis method and device, a terminal and a storage medium. The method comprises steps of classifying N ECU systems in a to-be-detected vehicle, and obtaining system types; N being greater than or equal to 2; based on the category number of the system categories, creating a target number of diagnosis threads; based on the diagnosis threads, parallel diagnosis being carried out on the ECU systems of different system types, and a corresponding initial diagnosis result output by each diagnosis thread being obtained; wherein each diagnosis thread only diagnoses the ECU system of one system category at the same time; and determining a target diagnosis result of the to-be-detected vehicle based on the initial diagnosis result. According to the method, diagnosis efficiency of a large number of ECU systems with complex relations can be improved, and meanwhile the accuracy degree of diagnosis results is improved.

Description

technical field [0001] The present application belongs to the technical field of vehicle diagnosis, and in particular relates to a vehicle diagnosis method, device, terminal and storage medium. Background technique [0002] The penetration rate of automobiles is getting higher and higher, and the development of vehicle technology is becoming more and more intelligent. In order to ensure the quality of vehicle production and the efficiency of vehicle maintenance, it is necessary to conduct accurate and efficient diagnostic tests on the on-board systems in the vehicle. [0003] At present, when performing fault testing or fault diagnosis on vehicles, due to the development of vehicle intelligence and diversified additional functions, there are a large number of ECU (Electronic Control Unit, electronic control unit) systems deployed in vehicles, and the differences between different ECU systems There may also be a certain interaction relationship. When scanning and diagnosing ...
