Abstract
A lane change warning system is proposed, which gets the surrounding vehicle's motion states based on V2V communication. The safe distance between the ego-vehicle and the rear vehicle in a target lane is analyzed according to the goal of both collision avoidance and vehicle following safety. Safe distance between the ego-vehicle and the front vehicle in the target lane is analyzed to ensure safety in emergency collision avoidance. Safe distances between the ego-vehicle and the front and rear vehicles in the original lane are analyzed to realize safe following. Meanwhile, a driving style index is proposed to adapt the warning system to different kinds of drivers. Simulation results show that the lane change warning system can make a composite analysis of the collision risk during the lane-changing, and provide an accurate real-time warning to assist drivers.
