Problems solved by technology

Diagnostic data such as diagnostic protocols, flashing files, and security algorithms are the core secrets of automobile manufacturers. Once leaked, it will cause major security risks to the vehicles they belong to.
However, since the diagnostic data are all included in the operating directory of the diagnostic software, once the diagnostic software is released, anyone who has the diagnostic software and a diagnostic instrument can flash and program the vehicle model. Management and control, diagnostic protocol data and flash files configured under the diagnostic software have the risk of leakage

Abstract

The invention discloses a vehicle fault diagnosis method. The method comprises the steps of receiving a fault diagnosis instruction; requesting to obtain a diagnosis file and license from a backgroundserver according to the fault diagnosis instruction; decrypting the diagnosis file by using the license to obtain diagnosis data; performing vehicle fault diagnosis by using the diagnosis data. According to the vehicle fault diagnosis method, a user can be effectively managed and controlled in the vehicle fault diagnosis process, diagnosis data leakage is avoided, and information safety is guaranteed. The invention further discloses a vehicle fault diagnosis device, equipment and a computer readable storage medium, which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of vehicle safety, in particular to a vehicle fault diagnosis method, and also to a vehicle fault diagnosis device, equipment, and a computer-readable storage medium. Background technique [0002] The initial automotive after-sales diagnostic systems are all stand-alone versions, and the diagnostic protocol and other data are configured in the diagnostic software running directory, or fixed in the program by code, and the user can execute all diagnostic protocols and functions supported by the diagnostic software without networking. . [0003] With the advent of the Internet of Things era, automobile manufacturers have higher and higher requirements for after-sales service quality, and the demand for unified management of user and diagnostic data is increasing. Diagnostic data such as diagnostic protocols, flashing files, and security algorithms are the core secrets of automobile manufacturers. On...
