基于微观车流的拟人化换道决策规划
A Humanized Lane-Changing Decision-Making and Planning Method Based on a Microscopic Traffic Flow Model
摘要
Abstract
To improve the safety and comfort of autonomous vehicles during lane changes,the proposed approach incorporates the impact of lane-changing on local traffic flow and introduces a lane-changing inertia factor based on traditional decision-making models.To overcome the limitations of decoupled longitudinal and lateral trajectory planning,a joint constraint planning approach is proposed.Using dynamic programming and quadratic programming algorithms,the current lateral trajectory curvature is adjusted based on the longitudinal constraints from the previous frame.In the longitudinal planning process,key obstacles are filtered based on the current lateral planning results,and curvature-based speed constraints are applied.The results from real vehicle experiments show that the proposed approach generates lateral and longitudinal lane-changing trajectories that effectively enhance the rationality,stability,and comfort of lane changes.关键词
