How does autopilot work?


Automatic driving is a relatively new technology and concept. In 1999, the automatic driving car Naclab-V developed by Carnegie Mellon University in the United States completed the first driverless test. Since then, automatic driving has come into reality. However, it was Tesla that really made the concept of automatic driving (assisted driving) popular more than a decade later.


There are 6 levels of automatic driving, and L0 level is completely driven by the driver; L1 level means that the vehicle can assist the driver to complete some driving tasks under specific circumstances; L2 level automated driving can complete some driving tasks, but the driver needs to constantly monitor the changes of the surrounding environment and be ready to take over in case of danger; At L3 level, the driver hardly needs to be ready to take over at all times, and the car can complete all actions independently; L4 and L5 levels are fully automatic driving, and the driver doesn’t need to control the car at all. However, L4 level can be completely independent only under specific conditions such as expressway, while L5 level is established under any conditions, including rainstorm, heavy fog, heavy snow and other complex environments.
