1. Urban NOA (Navigate on Autopilot) covers functions such as intelligent obstacle avoidance, cut-in avoidance, traffic light recognition and vehicle control, intelligent navigation following, and urban intersection navigation, making city driving safer and more convenient. The technical approach mainly includes "heavy perception" and "light mapping," with more comprehensive sensor configurations and increased computing power requirements.

2. Main challenges:

Higher demands on the perception system, requiring accurate detection of surroundings under various conditions; complexity of prediction and interaction; system strategy and safety assurance, considering various extreme scenarios.

Urban NOA is reshaping the competitive landscape of intelligent driving, with high costs and whether users are willing to pay sparking discussions and debates.
