[0003] Nowadays, the electronic control components of many vehicles have certain commonality. When the vehicle is being repaired or upgraded, the maintainer sometimes chooses to replace the non-original electronic control components for their own benefit. These non-original electronic control components are not strictly matched to the vehicle. Customization and testing, simply realize the basic functions according to the commonality, and the quality is uneven, especially the electronic control components related to the safety of vehicles and personnel (such as airbags and their controllers SRS, engine management system ECM, transmission control unit TCU , anti-lock braking system ABS, advanced driver assistance system ADAS, tire pressure monitoring system TPMS, etc.), there will be serious safety hazards and serious accidents; Replacing non-original electronic components cannot prevent this phenomenon from happening

Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0041] See Figure 1 to Figure 3 , a method for verification and matching of automotive electronic control parts, the MID, verification algorithm, matching algorithm and the reversible encryption and decryption algorithm to the password MK are burned into each module, and the comparison table of the MID and MK of each module and Burn the VIN of the vehicle into the erasable non-volatile memory of each module, and mark the MSF of each module as the certification status;
[0042] 1) The first module of each module is normally powered on, starts the background receiving function, stores and saves the received data information, and starts a 100 millisecond timer, which randomly generates a random number for verifying the algorithm when the timer is full x;
[0043] 2) Take the generated random number x as a value, and the unit is milliseconds, st...

The invention discloses a method for verifying the matching of automobile electronic control parts, for achieving encryption and verification replacement on the electronic control part; if the electronic control part influencing the safety of automobile driver and passengers is replaced by the non-original electronic control part, the automobile cannot start, and emits alarm sound and lights up a trouble light; if the important electronic control part not influencing the safety of automobile driver and passengers is replaced by the non-original electronic control part, the automobile can start and drive normally, and emits the alarm sound and lights up the trouble light; and if the other unimportant electronic control part is replaced by the non-original electronic control part, the automobile can start and drive normally, and intermittently emits the alarm sound.
Description
technical field [0001] The invention relates to the field of verification matching methods, in particular to a verification matching method for automotive electronic control components. Background technique [0002] Automobile technology, building technology and environmental protection are the three major symbols to measure a country's industrialization level; since the 1980s, improving automobile performance, saving energy and protecting the environment mainly depend on electronic control technology; in automobiles, electronic control technology is mainly used It is mainly used in vehicle dynamics, safety, comfort and entertainment communication information control. [0003] Nowadays, the electronic control components of many vehicles have certain commonality. When the vehicle is being repaired or upgraded, the maintainer sometimes chooses to replace the non-original electronic control components for their own benefit. These non-original electronic control components are n...
