A Car-Following Control Strategy for AEB Systems Balancing Safety and Comfort
摘要
Abstract
To address the difficulty of balancing safety and ride comfort,this paper proposes a new safety model considering both factors,and introduces a corresponding early-warning braking strategy.First,the second-order time-to-collision(TTC)model is constructed by incorporating the accelerations of both vehicles into the classical TTC model.Then the safety distance model based on braking process analysis is modified according to road conditions.Combining the safety and comfort requirements,the paper employs the second-order TTC model during the warning phase,and the modified safety distance model during the braking phase to judge dangerous states.The hierarchical AEB control system is designed,and co-simulation and real-vehicle test platforms are built for verification.The results show that,under various test scenarios,the proposed car-following control strategy for AEB systems successfully avoids collisions,initiates braking without disrupting normal driving,provides warning times that give the driver ample reaction time,keeps the minimum inter-vehicle distance after braking within a reasonable range,and achieves effective hazard avoidance even on wet roads.关键词
