Problems solved by technology
Excessive reliance on the protection of ground signal equipment, lack of active safety protection capabilities
[0007] 2. Failure to balance high efficiency and energy saving, or ignoring a certain aspect of demand
[0008] 3. Compared with the average level of manual driving, the ride comfort of passengers is still relatively insufficient
Compared with a series of cumbersome processes such as sign recognition, road recognition, pedestrian and vehicle recognition, and path planning in traditional automotive automatic driving systems, this solution is simple and direct, and the learning process is closer to the human driving learning process. There are quite a few companies that use this solution to carry out research and application of automotive autonomous driving technology, such as Nvidia, Comma.ai, Drive.ai, Momenta, PlusAI, etc., and most of them have achieved good initial results; however, these artificial intelligence solutions are not yet effective. Applied to train automatic driving technology
