液力自动变速器的换档控制策略

Shift control strategies of AT

从最佳动力性、最佳经济性换档规律的计算切入,同时指出基本换档规律存在的主要弊端,并针对这些弊端提出具体的驾驶员意图和上坡、下坡、低附着路面、拥挤市区等行驶环境的识别方法及相应的换档控制策略,以克服基本换档规律的不足,最后通过建立以驾驶员意图及行驶环境识别为基础的智能换档控制系统,实现汽车液力自动变速器的换档控制策略。

The thesis pays a great attention on the shift control strategies of AT. This chapter begins with the calculation of basic shift schedule, and meanwhile the disadvantages of basic shift schedule are pointed out. Then the methods of strategies are come up respectively. control system is set up. driver＇s intention and environment recognition and shift control With the analysis of these shift control strategies, an intelligent shift
