Problems solved by technology

The fault codes and their corresponding fault information are usually stored in the fault code database. Every time the user equipment reads the fault information represented by the fault code, it needs to access the fault code database. In the prior art, there are malicious attempts to obtain data in the fault code database. risk, resulting in less secure DTC library

Abstract

The invention is suitable for the technical field of vehicles, and provides a fault code library access control method and device, a a server and a storage medium. The access control method comprises the following steps: when an access request for a fault code library sent by user equipment is received, obtaining at least one fault code in the access request; obtaining at least one piece of fault information according to the at least one fault code; judging whether the access request is abnormal access or not according to the at least one piece of fault information; and if the access request is abnormal access, prohibiting the user equipment from accessing the fault code library. According to the invention, abnormal access to the fault code library can be prohibited, and the security of the fault code library is improved.

Description

technical field [0001] The present application belongs to the technical field of vehicles, and in particular relates to an access control method, device, server and storage medium of a fault code library. Background technique [0002] With the development of automotive electronics, electronic control units become more and more complex, and vehicle fault diagnosis becomes more and more important. The fault code of the vehicle is the fault code diagnosed by the electronic control unit (Electronic Control Unit, ECU) after the vehicle fails. The fault codes and their corresponding fault information are usually stored in the fault code database. Every time the user equipment reads the fault information represented by the fault code, it needs to access the fault code database. In the prior art, there are malicious attempts to obtain data in the fault code database. Risk, resulting in lower security of the fault code library. Contents of the invention [0003] The embodiment of...
