基于Cruise软件对某自动档轿车燃油经济性及动力性的仿真应用

Simulation Application of Fuel Economy and Power of One Automatic Vehicle based on Cruise

为了满足法规及顾客对自动档汽车燃油经济性的要求,需要对带锁止液力变矩器自动变速器(AT)的特性进行合理的设定。文章通过修正整车阻力模型,研究设定换档特性图及液力变矩器锁止特性图,对某自动档乘用车进行了仿真分析和验证。

In order to meet customer＇ s requirement of fuel economy of automatic vehicle, the characteristic of AT with lock-up clutch should be optimized. Through modification of the resistance model and research of the shifting program and lock-up program, the automatic vehicle is simulated and validated.
