AI Technical Summary

⚠Technical Problem

Existing technologies suffer from insufficient generalization and safety in longitudinal control of multiple traffic scenarios. Reliance on multiple model switching leads to strategy complexity and discontinuity, while end-to-end learning results in weak constraint guarantees and difficulty in suppressing boundary risks.

⚗Method used

By acquiring information on the vehicle's longitudinal operating status and traffic environment status, the nominal feasible speed range is determined, and a longitudinal risk characterization is constructed to generate longitudinal control commands. Traffic constraints and vehicle dynamics constraints are integrated to form a unified control framework. The longitudinal control model is trained using reinforcement learning to quantify the risk and generate continuous control commands.

🎯Benefits of technology

It achieves stable, safe and efficient longitudinal vehicle movement control in complex multi-traffic scenarios, enhances the interpretability and verifiability of control decisions, detects and suppresses high-risk boundary conditions in advance, and solves the problems of discontinuous control and low training efficiency in traditional methods.
