摘　　要：随着汽车技术不断发展,电子液压制动系统(EHBS)在汽车制动系统中的应用越来越广泛,但在急刹车时,由于车轮与路面之间的摩擦力过大,很易导致车轮抱死,从而影响制动效果和驾驶安全性。为解决这一问题,文章基于模糊逻辑控制方法,提出一种电子液压制动系统的防抱死控制策略。文章通过分析车辆制动过程中的物理特性,建立电子液压制动系统的数学模型。然后,根据车辆的实时制动状态和路面摩擦系数等信息,设计一套模糊逻辑控制器。为验证所提出的防抱死控制策略的有效性,进行一系列的仿真实验。结果表明,所设计的模糊逻辑控制器在不同驾驶条件下实现良好的防抱死效果,且具有较高的稳定性和鲁棒性。此外,与传统PID控制方法相比,基于模糊逻辑的防抱死控制策略在制动性能和驾驶安全性方面具有更好的表现。With the continuous development of automobile technology,electronic hydraulic braking system(EHBS)is more and more widely used in automobile braking system,but in the emergency braking,due to the excessive friction between the wheel and the road,it is easy to lead to wheel lock,which affects the braking effect and driving safety.In order to solve this problem,an anti-lock control strategy of EHBS is proposed based on fuzzy logic control method.This paper establishes the mathematical model of EHBS by analyzing the physical characteristics of vehicle braking process.Then,a fuzzy logic controller is designed according to the information of real-time braking status and road friction coefficient.In order to verify the effectiveness of the proposed anti-lock control strategy,a series of simulation experiments were carried out.The results show that the designed fuzzy logic controller can achieve good anti-lock performance under various driving conditions,with high stability and robustness.Furthermore,compared with the traditional PID control method,the anti-lock control strategy based on fuzzy logic has better performance in braking performance and driving safety.
