The thesis brings a new method of design a universal automobile brake system test instrument 本文提出了一种通用汽车制动系综合测试系统的设计方法。
Motor vehicles - hydraulic braking systems - pipes , tapped holes , male fittings and hose end fittings 汽车液压制动系金属管内外螺纹管接头和软管端部接头
It can keep the vehicle at retard and on cruising easily , so improve the driving safety and handling quality 其作用原理与传统制动方式不同，有延长传动系和制动系寿命的功效。
Secondly , the simulation program for tire - model , vehicle body model , braking system model and road surface model are developed with c + + language 随后用c + +语言对车体模型、轮胎模型、制动系模型和路面模型进行了二次模型化。
The dedicated portable integrated test system of automobile braking has been designed as the typical application of field test instrument in automobile test field “车载式汽车制动系综合测试系统”是在线测试技术在汽车工业领域的典型应用。
As the parameters to be tested of automobile brake system are more and more complex , the traditional test technique could not meet the current requirements gradually 随着汽车制动系被测参数复杂程度的增加，传统测试方法越来越不能满足要求。
Firstly , methods of founding vehicle dynamics model , the mathematical models of tire , vehicle body , braking system and road surface are discussed and studied 首先研究分析了汽车动力学建模的各种方法，现有的各种车体模型、轮胎模型、制动系模型和路面模型。
To simply controller design low dimension models ( including longitudinal dynamics , engine and brake model ) based on analysis and experiment are developed 在机理分析基础上建立了适合于控制应用的车辆动力学模型、发动机及制动系子模型及相应的纵向运动控制律。
The brake system in ev and hev which are of regenerative braking is different from the conventional friction braking system in certain aspects . its braking stability would change during braking besides it can recover kinetic energy of the vehicle 具有再生制动功能的电动汽车制动系与传统燃油汽车的摩擦制动系有所不同,除了能回收部分制动能外,其制动时的制动稳定性也将发生变化。
