摘　　要：在对目前金属带式无级变速器(CVT)通用的夹紧力控制方法分析的基础上,提出了一种在做出驾驶员想要急加速的判断后,以行车速度及节气门开度为输入量,利用模糊控制的方法对提前夹紧力进行控制,以满足汽车在该工况时大扭矩输出的要求。利用这种方法就可以在汽车行驶于稳定工况时降低夹紧力的输出,减小能量损失,达到提高汽车经济性的目的,同时在急加速时能够提供足够的夹紧力保证汽车的动力性。Based on the analysis of clamping contrlol methods used in metal V-belt continuously variable transmission,a new method is introduced. After judgement of driver＇s fast accelaration intention, clamping force is controlled by fuzzy control strategy to satisfy big torque output under this driving condition with the inputs are set as vehicle speed and throttle angle. Using this method,the clamping force can be reduced during stable driving condition,so will be the loss of power. A nd the economical efficiency of vehicle wil! inerease ,meanwhile ,the power performance will also be improved because of enough clamping force.
