【摘要】 在汽车动力学的研究中,对研究对象进行数学建模是一种非常普遍的方法。而在此基础上发展起来的动态仿真技术则是进行汽车性能研究的一种行之有效的手段。文中结合逻辑门限控制的方法,建立汽车ABS制动过程的动态数学模型,包括整车、制动器、轮胎以及控制器4个子模型。用Matlab对所建立的数学模型编制仿真程序。通过对制动过程的模拟仿真,探讨不同因素对ABS性能的影响,为汽车制动系统的设计开发提供参考。更多还原

【Abstract】 A good method to study vehicle dynamics is to construct a vehicle mathematical model.The dynamic simulation is one of the best means for vehicle performance research,which is developing based on the model.A mathematical model is set up according to the logic gate control,including vehicle model,braking model,tire model and controller model.A computer simulation program is written with Matlab.Through the computer simulation,the thesis discusses the main factors which influence the performance of ABS,and finds suitable control logic,the dynamics model which is built in this thesis is helpful for the vehicle design and ABS developing.更多还原
