摘要
以在坡度为α的坡道上制动的汽车为研究对象,结合整车和前、后车轮的旋转运动微分方程,建立轮式汽车制动的力学模型,利用工程仿真软件Matlab中Simulink模块,建立轮式汽车制动的仿真模型,将某车型的参数代入仿真软件进行数值模拟仿真。分析轮式汽车制动时滑移率的影响规律得出:在相同的道路附着系数条件下,车速越高滑移率越大,制动距离越长;设计汽车时适当地增加汽车制动器的制动力,增大速率,可以控制滑移率的增长速度。
Abstract：Taking the down hill braking car as the research object with the slope is a,combining with motion differential equations of the whole vehicle and of the front and hear wheels, the mechanical model of the braking wheeled car was established, and the in- fluence law of slip rate of one brand car was simulated when the car braking, using Matlab/Simulink module. The results：with the same adhesion coefficient conditions ,the speed is higher, the sliding rate is bigger, and the braking distance is longer. By adding properly the velocity of increase of automobile brake when designing car, the increment speed of the slip rate can be controlled.
