Problems solved by technology

[0002] With the gradual development of unmanned driving technology, people have higher and higher safety requirements for unmanned vehicles. Since the safety of unmanned driving is closely related to the gear control of unmanned vehicles, how to improve the safety of unmanned vehicles The safety of gear control and the improvement of the safety of unmanned driving have become issues that need to be considered, and the current unmanned vehicle gear control technology is mainly designed based on the network architecture of unmanned vehicles. When the network architecture changes, the corresponding gear control method also needs to be adjusted. Therefore, the existing unmanned vehicle gear control technology still has problems of low security and low universality.
