建立了电机控制的金属带式无级变速器的动力学模型,并通过仿真,研究了其速比变化率对车辆性能的影响.为某车型装备此类CVT提供了控制电机转速范围选择的依据.%A dynamics model for the motor-controlled metal V-belt CVT is built and the effects of its changing rate of speed ratio on the performance of vehicle are studied by simulation. This provides a basis for selecting the speed range of control motor for a vehicle equipped with this type of CVT.
