Automobile CAN communication interruption protection control method

Abstract

The invention relates to the technical field of Internet of Vehicles, and provides an automobile CAN communication interruption protection control method. The method specifically comprises the following steps that: S1, a T-box receives a whole vehicle network disconnection instruction sent by a mobile terminal, and uploads the vehicle network disconnection instruction to a CAN wiring harness; S2,the vehicle body controller BCM and the engine controller MCU are awakened based on the vehicle network disconnection instruction, the vehicle body controller BCM uploads the vehicle network disconnection instruction, and the instrument reads the vehicle network disconnection instruction; S3, the instrument monitors whether the whole vehicle meets a CAN communication interruption condition or notin real time based on the whole vehicle network disconnection instruction; if the detection result is yes, the CAN communication of the whole vehicle is interrupted, and CAN communication interruptioninformation is fed back to the instrument, and based on the network communication architecture of the whole vehicle, a control method for interruption and recovery of the CAN communication network ofthe whole vehicle is designed, network communication interruption control of the vehicle is quickly achieved, and the control feeling of a user on the vehicle is improved; and, in addition, the situation that a traditional automobile depends on the passive anti-theft function of an automobile body anti-theft system is improved, and active protection of the automobile is achieved.

Description

technical field [0001] The invention relates to the technical field of CAN communication, and provides an interruption protection control method for automobile CAN communication. Background technique [0002] With the rapid upgrade of automotive electronic technology, the number of electrified systems on the vehicle is increasing, and the amount of information exchange and communication data between vehicle controllers is also increasing, involving vehicle information related to driving safety, functional safety, and operator privacy. Also showing 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 cars in the current market in terms of network communication are extremely limited, mostly from the aspects of network encryption and information routing. Network security protection. At th...
