摘　　要：针对自动紧急制动系统兼顾制动效能和制动舒适性的要求,设计了两级自动紧急制动系统控制策略。选取具有丰富驾驶经验的驾驶员在驾驶模拟器硬件在环试验台上进行试验,利用驾驶员实际制动数据确认驾驶员最舒适制动减速度,以此在单级自动紧急制动强度的基础上,建立了考虑前车运动状态的两级自动紧急制动安全距离模型和两级自动紧急制动系统控制策略,并通过驾驶模拟器硬件在环试验对所设计的控制策略进行验证。结果表明:两级自动紧急制动系统能够有效防止紧急制动车辆发生碰撞危险,具有良好的驾驶辅助功能。A two-level automatic emergency braking system control strategy is designed for the requirement of braking efficiency and braking comfort in automatic emergency braking system.The drivers with rich driving experience were selected to carry out the experiment on the driving simulator hardware in loop test bench,and the driver's actual braking data is used to confirm the driver's most comfortable braking deceleration.Based on the single-level automatic emergency braking strength,a two-level automatic emergency braking safety distance model and two-level automatic emergency braking system control strategy are established,and the control strategy is verified by the driving simulator hardware in the loop test.The results show that the two-level automatic emergency braking system can effectively prevent the collision risk of emergency braking vehicles,and has good auxiliary driving function.
