基于车辆负荷度的挡位决策研究

Shift Strategy Research Based on Vehicle Load Degree

针对货车自动变速器的特性,提出了车辆负荷度的概念,并利用模糊控制的方法,对货车制定了相应的挡位决策,解决了货车自动变速器不同于轿车自动变速器的一些关键问题。在轻型货车上实验表明,该方法对车辆载荷及环境有较强的适应性,对开发具有自主知识产权的货车电控机械式自动变速器有重要意义。

According to the automated transmission characters of the truck,the concept of the vehicle load degree is advanced, and the shift strategy of the truck is made with the use of fuzzy control method. Some key problems of the automated transmission of truck which is different from the one of car are solved. The test results in light truck showed that this method is very suitable to vehicle load and environment. There is a significant meaning for developing the electronically automated mechanical transmission of the truck with independent intellectual property rights.
