以MATLAB软件的GUI为设计工具，建立了汽车动力性数学模型，通过最小二乘法和插值法绘制了发动机外特性曲线、汽车驱动力与行驶阻力平衡图、加速度倒数曲线、爬坡度曲线，以及加速时间曲线、最高车速变化曲线、加速度变化曲线和爬坡度变化曲线，直观、清晰地分析了汽车的动力性和各参数对动力性灵敏度的影响，使设计者清楚地了解汽车的动力性好坏以及各参数的影响，进而对设计作出改进。

Mathematical model of automobile dynamic performance is established based on Matlab/GUI,the program can fit the engine′s external characteristic curve, automobile driving force and driving resistance equilibrium diagram, vehicle acceleration reciprocal curve and the car′s climbing curve, and the changing curve of these dynamic indicators. Through the graphic, we can analyze the vehicle′s dynam?ics performance and the sensitivity of the vehicle′s parameters,and improve the design.
