摘要/Abstract

摘要： 为应对景（园）区内行人横穿等复杂情况，提高自动紧急制动（AEB）对行人保护的安全性。文章建立了某智能接驳车在路面激励特性和车辆特性前提下的动力学模型，提出了基于模糊推理的智能接驳车 AEB 控制算法，通过 MATLAB/Simulink 仿真软件对控制算法进行仿真，并将该算法应用到实车测试，与传统控制算法进行了比较试验。结果表明，接驳车在 5.14 s 全力制动时比传统值（5.35 s）快 0.21 s；接驳车刹停后，距离行人安全距离传统值为 1.53 m，优化值为 1.91 m，两者误差为 0.38 m，优化后更加精确安全，能有效避撞的同时也说明了该算法的可行性。

Abstract: To improve the safety of autonomous emergency braking (AEB) for pedestrian protection in complex situations such as pedestrian crossing in landscape (garden) area. In this paper, a dynamic model of an intelligent shuttle bus under the conditions of road excitation characteristics and vehicle characteristics is established, and an intelligent shuttle bus AEB control algorithm based on fuzzy reasoning is proposed. The control algorithm is simulated by MATLAB/Simulink simulation software, and the algorithm is applied to the real vehicle test and compared with the traditional control algorithm. The results show that at 5.14 s full braking, the shuttle is 0.21 s faster than the traditional value of 5.35 s. When the shuttle bus is stopped, the safety distance from the pedestrian is 1.53 m, the optimal value is 1.91 m, and the error of both is 0.38 m, which is more accurate and safe after optimization, and can effectively avoid collisions, and also shows the feasibility of the algorithm.
