Problems solved by technology

[0005] The user needs to manually input various configuration information of the vehicle, and this manual input process is generally error-prone and low in efficiency; in addition, the existing on-board diagnostic system needs to be connected to the Internet and interact with the server online to complete the learning and matching of the CAN protocol. A process of learning the CAN protocol. When a problem occurs, it is not easy to confirm the problem point due to the existence of interaction, and it is dependent on the network

Abstract

The embodiments of the invention provide a method for matching a vehicle CAN protocol and correlation equipment. The method and the equipment are used for automatically matching the vehicle CAN protocol so as to increase the convenience of vehicle parameter acquisition and the diversity of vehicle parameters. The method comprises the following steps of sending a VIN code acquisition request to a vehicle through the OBD interface of the vehicle; when the vehicle supports the VIN code acquisition request, receiving and parsing a VIN code to obtain the configuration information of the vehicle, and determining the vehicle model ID of the vehicle according to the configuration information of the vehicle; locally finding all CAN protocols corresponding to the vehicle model ID in matching equipment according to the vehicle model ID; monitoring the bus broadcast of the vehicle and collecting bus data; matching the bus data with all the CAN protocols corresponding to the vehicle model ID; and if the matching is successful, setting the successfully-matched CAN protocol to be the CAN protocol of the vehicle.

Description

technical field [0001] The present application relates to the technical field of vehicle diagnosis, in particular to a method for matching a vehicle CAN protocol and related equipment. Background technique [0002] With the popularization of personal vehicles, the safety of vehicles has become a problem that cannot be ignored, and the application of vehicle diagnostic equipment to electronic control units (ECUs) of vehicles to realize real-time monitoring of vehicle status parameters is becoming more and more popular among car owners. Pay attention to. [0003] The existing on-board diagnostic system (OBD, On-Board Diagnostic), as a system for monitoring vehicle parameters, has become the primary choice of many car owners because it covers a wide range of vehicle models and supports reading a lot of vehicle data. As a serial communication protocol bus for real-time applications, CAN (ControllerArea Network) is used in communication between OBD products and various component...
