基于前车换道意图识别与车车通信的汽车切入防撞预警模型
A Cut-in Collision Avoidance Warning Model Based on Front-Vehicle Lane-Change Intention Recognition and Vehicle-to-Vehicle Communication
摘要
Abstract
Existing driver-assistance systems often deliver late or inaccurate alerts when a vehicle cuts in suddenly from an adjacent lane.To address this issue,the paper develops a collision-warning model that detects the lane-change intention of the lead vehicle.The vehicle-vehicle communication is utilized to send that intention to the following vehicle,which then predicts the cut-in path and performs collision detection.The collision time TTC-S is proposed,the avoidance time TTA is re-examined,and a tiered warning strategy is designed.In order to verify the effectiveness of the collision warning system,a joint simulation platform is built based on Simulink and PreScan.The results show that the collision-warning model achieves an average true-positive rate of 90.32％,outperforming the Mazda model by 8.44％and the traditional TTC model by 11.66％.The system also provides earlier alerts,extending the average warning lead time by 1.42 s and 1.9 s,respectively,which provides a larger safety margin.关键词
