摘要
汽车安全状态判断是实现汽车主动避障系统功能的重要部分.文中在建立汽车安全状态判断模型时,综合考虑了汽车轮胎路面附着系数、前车运动状态以及驾驶员心理因素的影响,建立了一种改进的安全状态判断模型;通过搭建Carsim和Matlab/Simulink联合仿真模型对所提出的安全状态判断方法进行仿真分析.仿真结果表明,所建立的安全状态判断方法和传统的安全状态判断方法对比,能够在保证安全的同时,有效的增加道路交通利用率.
The judgement of vehicle safety state is an important part of realizing the function of active obstacle avoidance system.In this paper,the influence of the tire road adhesion coefficient,the front car movement state and the driver's psychological factors are taken into consideration in the model of automobile safety state judgment,and an improved safety state judgment model is established.By building the combined simulation model of Carsim and Matlab/Simulink,the proposed method of the safety state judgement is simulated and analyzed.The results of the simulation show that the established safety state judgement method comparing with the traditional methods can effectively increase the road traffic utilization rate while ensuring the safety.
