A vehicle can bus data interaction system and its interaction method

Abstract

The invention discloses a vehicle CAN bus data interaction system and an interaction method thereof, which has both safety and cost considerations. On the hardware, the CAN bus data interaction module is set on a third-party vehicle monitoring terminal to reduce equipment redundancy and reduce In terms of software, by writing its own bus communication protocol and encryption mechanism in the CAN bus data interaction module, the operating data of the vehicle's CAN bus equipment can be transparently transmitted to the car factory data through the third-party vehicle monitoring terminal In the platform, at the same time, the car factory does not need to open the bus communication protocol of the vehicle to the third party, which can effectively guarantee the data security of the vehicle CAN bus and protect the data value of the car factory.

Description

technical field [0001] The invention relates to the field of vehicle data interaction, in particular to a vehicle CAN bus data interaction system and an interaction method thereof. Background technique [0002] In recent years, with the popularization of 3G / 4G wireless communication technology and the promotion of national-level intelligent network connection and new energy vehicle industry policies, the Internet of Vehicles data collection and monitoring platform based on the device-pipe-cloud architecture design has been basically completed and deployed in major Commercial vehicle factories promote the use. With the advent of big data artificial intelligence technology, people pay more attention to the data security of the Internet of Vehicles and the value brought by the analysis and mining of data. Data becomes the energy and raw materials of the intelligent era, and vehicle operation data will also become The important assets and core values ​​of car companies. [0003...

AI Technical Summary

Problems solved by technology

Third-party vehicle monitoring terminal manufacturers must connect to the CAN bus network of the vehicle to collect vehicle CAN bus data. Since the vehicle monitoring terminal is a networked device, there are hidden dangers of various data security attacks from the network. The bus communication protocol is not conducive to the confidentiality and security of data for third-party terminal manufacturers, and will also pose a security threat to the vehicle CAN bus network
