ABSTRACT
In order to enable the automatic transmission shifting of the AMT vehicle to reflect the changes of road conditions and vehicle conditions, and to meet the requirement of shifting smoothness of the vehicle, we studied the fuzzy three-parameter shifting control of the AMT vehicle and put forward that acceleration should be used to reflect the changes of road conditions. This paper will introduce the principle of fuzzy three-parameter shifting control at first, and then it will show the design of fuzzy three-parameter shifting controller. Finally, it will give the fuzzy three-parameter shifting simulation of a certain model of AMT car produced by Changan Automobile. In addition, we will also compare it with the fuzzy two-parameter shifting. The result shows that the fuzzy three-parameter shifting is fit with drivers’ shifting experience and habits than the two-parameter shifting. And compared with solving the shifting rules with traditional calculation method, it is more convenient and easier to be implemented with stronger robustness.
