摘要路面附着系数是影响车辆行驶安全性的重要因素，利用轮边驱动电动汽车驱动力矩可以对路面利用附着系数进行观测。 - Based on the confirmation of driving force of lunar rover , we analyze the relationship between adhesion coefficient of road surface and wheel slip . in our research , several types of wheel force model are referenced among them , and we select the polynomial model with exponential function as the wheel force model of the lunar rover
围绕月球车驱动力的确定,本文分析了路面附着系数与滑转率的关系,以车辆动力学分析中常用的几种车轮力模型为基础,选择了带有指数函数的多项式模型作为分析月球车车轮附着力的模型。 - Detailed contrastive simulation tests of four - phase and self - optimalizing abs control have been made and applying effects of self - optimalizing control are discussed , which establish stable principle foundation for self - optimalizing control applying to realistic abs controller . from the simulation results we can find that : automobiles which install self - optimalizing abs apparatus lock on the any road surface only when the vehicle body velocity and wheel velocity arrive at zero approximately , which is better for improving driving stability under braking . it shows anti - lock ability of self - optimalizing ; slip ratio approximates and surround the desired slip , which shows that this abs system uses fully road surface performance and retains large adhesion and braking performance is good ; braking force regulates with varies of road condition , which realizes road self - identification
通过仿真试验可以看出：在各种路面上，汽车在安装了自寻优防抱制动装置后，在车速、轮速接近为0时才抱死，这对提高汽车制动时的操纵稳定性特别有利，显示了自寻优避免车轮抱死的能力：滑移率的值基本上一直接近并且围绕着与路面附着系数相对应的滑移率上下变化，说明了该系统充分利用了路面性能，基本上保持了较大的附着力制动，制动性能较好；制动力随着路面条件的变化而相应做出调整，实现了路面自动识别的功能。 - Accordingly a top town vehicle braking model is built with the foundation of vehicle , tire and road adhesion model , meanwhile emb and hb braking system are introduced for contrast and simulation of braking efficiency , the result is prove to be better and higher response speed for the new designed system . additionally , primary anti - rollover analysis for the emb braking system is included in this paper
因此,根据车辆的动力学模型、轮胎动力学模型、路面附着系数模型等建立了综合的整车制动模型,并把emb制动系统和hb制动系统引入到模型中,进行了制动效能的对比仿真,仿真结果表明emb制动系统具有比传统制动系统更好的制动效能和更快的响应速度。
