摘　　要：近年来,自动紧急制动(AEB)系统被越来越多的研究,以提高车辆的安全性。由于驾驶员倾向于过度依赖主动安全系统,自动紧急制动的设计需要反映真实的路面情况,如各种路面坡度和摩擦系数。文章提出了一种自动紧急制动控制算法来补偿斜坡和路面摩擦力的影响。基于真实路况下的最大可能减速度,用裕度参数来描述最小制动距离。设计了带前馈项的减速控制器,以避免自动紧急制动系统在真实路况下运行时发生碰撞。对所提出的算法进行了仿真验证,并在不同坡度条件下进行了实验验证。In recent years,automatic emergency braking(AEB)systems had been studied more and more to im・prove vehicle safety.Since drivers tended to over-rely on active safety systems,the design of automatic emergency braking needed to reflect real road conditions,such as various road slopes and friction coefficients.In this study,an AEB control algorithm was proposed to compensate for the influence of slope and road friction.Based on the maximum possible deceleration under real road conditions,the margin parameter was used to describe the minimum braking distance.A deceleration controller with feedforward term was designed to avoid collision of the AEB system in real road condition.The proposed algorithm was verified by simulation and experiment under different slope conditions.
