全时四驱SUV爬坡性能分析与优化
Analysis and Optimization of Climbing Performance for an All Wheel Drive SUV
摘要
Abstract
In order to improve climbing performance of vehicle,the analysis and optimization of the climbing performance of an all wheel drive (AWD) SUV (Sport Utility Vehicle) is researched.Taking the wind resistance into consideration,a dynamic model of an AWD SUV is established,and the theoretical maximum climbing degree is calculated from the driving force condition and the ground attachment condition respectively.The AVL Cruise is applied to verify the theoretical model.The climbing degree of AWD,front drive and rear drive SUV with the same vehicle parameters are compared.To enhance the climbing performance,the genetic algorithm is used to optimize vehicle.parameters.The results show that the climbing degree of AWD drive is better than that of the front and rear drive with the same vehicle parameters,and the optimization algorithm can significantly improve the climbing performance under the constraint of fuel economy.关键词
