摘　　要：分析汽车制动过程时普遍采用的制动模型是从车体受力角度建立的。提出一种基于动能转化建立制动模型的新方法。该方法根据车体动能主要消耗在轮胎与地面的摩擦和制动器内摩擦的原则,推导出制动过程的数学模型。为验证制动模型的正确性,在Matlab/Simulink环境下对安装防抱死制动系统(ABS)的模型和未安装ABS的模型进行仿真实验。仿真实验结果与装有防抱死制动系统的车体道路试验结果相比较,结果表明基于动能转化方法分析制动过程是可行的。When analyzing the braking process, it is used to establish the braking model according to the force on the vehicle. This paper puts forward a new method which based on the kinetic transformation. The kinetic is worn down by friction that come from the wheel and braking block and a mathematical model is deduced from this principle. For the purpose of validating this theory, anti-lock brake system （ABS）-e- quipped model and ABS-unequipped model are simulated in the Matlab/Simulink environment. The comparison between the simulation results and the road test ABS-equipped results shows that kinetic transformation method is feasible to analyze the braking process.
