A method for protection and control of automobile CAN communication interruption

Abstract

The present invention relates to the technical field of Internet of Vehicles, and provides a method for protecting and controlling automotive CAN communication interruption. The method specifically includes the following steps: S1, T-box receives a vehicle network disconnection command sent by a mobile terminal, and uploads it to the CAN wiring harness; S2. The body controller BCM and the engine controller MCU wake up based on the vehicle network disconnection command, the body controller BCM uploads the vehicle network disconnection command, and the instrument reads the vehicle network disconnection command; S3. The instrument is disconnected based on the vehicle network The instruction monitors in real time whether the vehicle meets the CAN communication interruption condition. If the detection result is yes, the CAN communication of the vehicle is interrupted, and the CAN communication interruption information is fed back to the instrument. Based on the vehicle network communication architecture, a vehicle CAN communication is designed. The control method of interruption and recovery of the communication network quickly realizes the interruption control of the network communication of the vehicle, and improves the user's sense of control over the vehicle; in addition, it improves the passive anti-theft function of the traditional automobile relying on its own body anti-theft system to realize the active protection of the vehicle.

Description

technical field [0001] The invention relates to the technical field of CAN communication, and provides an automotive CAN communication interruption protection control method. Background technique [0002] With the rapid upgrading of automotive electronic technology, the number of electrified systems carried by the vehicle is increasing, and the amount of information interaction and communication data between vehicle controllers is also increasing, involving vehicle information related to driving safety, functional safety, and operator privacy. also showed explosive growth. Compared with the comprehensive and complete security protection system of the computer network, limited by the network structure of the whole vehicle and the equal factors of the current technology, the measures taken by the vehicles on the current market in terms of network communication are extremely limited, mostly from the aspects of network encryption and information routing. Carry out network secur...
