摘要
车辆自动紧急制动系统AEB能够显著地提高车辆行驶过程中的安全性,因此,针对AEB系统相关技术和控制策略的研究有着重要的现实意义。文章介绍AEB系统的工作原理以及各部分组成及功能,分析国内外AEB系统测试方法。对比现有安全距离模型,并基于分层控制的思想,进行控制策略优化设计。进一步选用某款乘用车实际的整车参数,确定合理的模型参数值,搭建Carsim/Simulink联合仿真模型。最终根据C-NCAP(2018版)规定的测试要求,对建立的分层控制策略分别进行车辆三种典型工况仿真试验,研究验证其对整车精确控制的有效性。
The vehicle AEB system can significantly improve the safety of the vehicle during driving.Therefore,the research on the related technologies and control strategies of the AEB system has important practical significance.This paper introduces the working principle of the AEB system,the composition and functions of each part,and studies and analyzes the AEB system test methods at home and abroad;compares the existing safety distance model,and optimizes the control strategy design based on the idea of hierarchical control;further selects the actual vehicle parameters of a certain passenger car,determines the reasonable model parameter values,and builds a Carsim/Simulink joint simulation model;finally,according to the test requirements specified by C-NCAP(2018 version),the established hierarchical control strategy is simulated under three typical working conditions of the vehicle to verify its effectiveness in precise control of the whole vehicle.
