By setting the identification code and the flag in the mode recognition module, the driving mode is locked and monitored to avoid program jump errors during the operation of the system as a whole, thereby improving the recognizability of the system during operation.

[0023] 3. In the intelligent mode of the present invention, the system performs logical judgment on the working state of the motor system, the fault level, the working state of the remote control key and the main driver's seat sensor.

[0025] 5. When the present invention performs intelligent driving or unmanned driving functions, because different people have different risks when using this function, the system can enter the third condition judgment to confirm the condition by setting an exclusive mode. When the working state of the motor system, the system fault level, the working state of the remote control key, the main driver's seat sensor and the face recognition authentication all meet the requirements, the mode recognition module can send a high-voltage command to ensure that the vehicle is the designated driver of the vehicle system and can activate the relevant function;

[0026] 6. Each submodule in the first confirmation module of the present invention verifies the identification code in the pattern recognition module through logical judgment. If the corresponding identification code is met, the corresponding conditional judgment is entered for conditional confirmation. The system jump can be verified by verifying the identification code to ensure that the judgment logic performed is the corresponding identification mode, and the security verification function can be realized by this identification code method to prevent the system from being deceived by the illegal intrusion signal of the vehicle and causing the vehicle to be stolen. This anti-theft method is of great significance to the safe use of intelligent vehicles. BRIEF DESCRIPTION OF THE DRAWINGS
