- Abstract:
-
To achieve safe and efficient lane-changing of autonomous vehicles in complex traffic environments, a lane-changing strategy based on multi-objective constraints is proposed. Driving dissatisfaction is decomposed into speed dissatisfaction and space dissatisfaction, which are used to evaluate the current lane condition and generate lane-change intentions. A lane evaluation function is established to quantitatively assess candidate lanes and determine the optimal target lane. Within a connected vehicle environment, constraint checks are conducted from the perspectives of legality, safety, and altruism, and lane-changing is executed only when all constraints are satisfied. A quintic polynomial is employed for lane-change trajectory planning, and efficiency and comfort weights are introduced to balance lane-change efficiency and ride comfort. Results from CarSim–Simulink co-simulation and vehicle-in-the-loop experiments demonstrate that the proposed strategy meets multi-objective constraint requirements and achieves stable and reliable lane-change decision-making and execution. Specifically, the maximum yaw angle is 3.45 deg, the maximum lateral acceleration is 1.31 m/s², and the maximum trajectory tracking errors are 0.02 m in the lateral direction and 0.012 m in the longitudinal direction. These results verify that the proposed decision model can achieve precise lane-change control with satisfactory performance.
