AI Technical Summary

Problems solved by technology

The problems arising from both are: the virtual simulation test can only be used as an auxiliary verification, the fidelity of the virtual environment is not enough, and it cannot be completely based on the simulation test results
The road test of real vehicles will face many limitations, such as long test cycle, which greatly affects the efficiency of autonomous driving technology research and development, huge test cost and driving safety issues, etc.
When using scene simulation to carry out real vehicle simulation test, the scene needs to be closely coordinated with the test vehicle, and the design with low precision will make the environment and the test vehicle disconnected, showing lag, and affecting the intelligent driving of the test vehicle and the decision-making of the ADAS system
