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.
