Zusammenfassung:The present invention discloses a method of shifting a transmission. A method of controlling a continuously variable transmission (CVT) simulates a step-ratio transmission upshift. In order to simulate a step-ratio torque phase, the input torque is gradually reduced before beginning to change the variator ratio. Then, as the variator ratio is changed, the input torque is gradually increased to compensate for the decreasing torque ratio, thereby simulating the relatively constant output torque of an inertia phase of a step-ratio upshift. 本发明公开种变速器换挡方法。种控制无级变速器(CVT)的方法模拟阶梯传动比变速器升挡。为了模拟阶梯传动比扭矩阶段,在开始改变变速机构传动比之前逐渐地减小输入扭矩。然后,随着变速机构传动比的改变,逐渐地增加输入扭矩以补偿减小的扭矩比,从而模拟阶梯传动比升挡的惯性阶段的相对恒定的输出扭矩。
