【摘要】 考虑汽车旋转质量换算系数、滑移率等影响因素,建立了汽车联合制动系统的数学模型,并在Matlab/Simulink中建立其仿真模型进行仿真分析。仿真结果表明:联合制动系统,在紧急制动时,能够减少制动距离,提高汽车的制动效能;在非紧急停车时,缓速器消耗了汽车的绝大部分能量,降低了汽车维护成本;在坡道上持续制动时,能使汽车以经济、稳定的车速行驶。更多还原

【Abstract】 The math model of united brake system is set up on thinking of the influence of the coefficient of the revolving mass changes to linear mass,the efficiency of slippage and so on.The simulation model is set up in the Simulink module of Matlab.The result of simulation shows that the braking distance is shortened by the united brake system in the emergency brake,the braking ability of the automobile is advanced;The united brake system can also be used to stop automobile in the nonemergercy brake.The retarder exhausts most of energy of automobile.Thus,the maintenance cost is reduced;The automobile can run at steady and economic speed on the hillside path with continuous brake of united brake system.更多还原
