Abstract

The invention discloses a vehicle diagnosis method and device, equipment and a readable storage medium. The method comprises the following steps of performing authorization check on a vehicle diagnosis file locally stored, and deleting the vehicle diagnosis file exceeding authorization validity; receiving and analyzing a vehicle diagnosis request, and determining a target vehicle model diagnosed by the request; acquiring newest diagnosis file version number of the target vehicle model from a server; acquiring a target diagnosis file corresponding to the newest diagnosis file version number; and diagnosing the vehicle by the target diagnosis file, and acquiring a diagnosis result. In the method, corresponding vehicle terminal files are respectively stored according to the vehicle model, local storage validity is set, cleaning is performed at expiration time, the newest diagnosis filer version number is taken as a bond when vehicle diagnosis is needed, the target diagnosis file is acquired to complete diagnosis, the safety of the vehicle diagnosis file is guaranteed, and the reliability of the vehicle diagnosis result is also ensured.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a vehicle diagnosis method, device, equipment and readable storage medium. Background technique [0002] With the continuous update of vehicle technology, the data of vehicle ECU (Electronic Control Unit, also known as "driving computer", "vehicle computer", etc.) is also increasing, which is a great challenge to traditional diagnosis. ECU's The increase means that the diagnostic process will continue to increase, and the diagnostic workload will also continue to increase. [0003] In order to solve this problem, ODX technology was proposed. OXD is an open diagnostic data format for the interaction of diagnostic data in the vehicle life cycle. Due to the open source and standardized nature of ODX data, using ODX as a data exchange format in the vehicle diagnosis process will make the entire process easier, faster, and less likely to make mistakes. [000...
