Convention V-belt Continuously Variable Transmission, shifts gears the travel mechanism property fixed constraint, unable full into full play initiative control advantage, to engine and Transmission on the go to hold optimum match, Also takes into consideration acceleration and fuel consumption performance, so this paper research Motorcycles with an Electronically-Controlled Continuously Variable Transmission shift gears planning, to use motor power screw, we shall revolve motion changes rectilinear motion, to push driving sheaves achieved to change speed ratio; Comparison between analysis convention CVT speed ratio shift gears curves of acceleration and fuel consumption performance optimum curves, use engine can hold high performance output or low fuel consumption region run.

中文摘要传统皮带式无段变速器(Continuously Variable Transmission， CVT)，换档行程由於机械特性的限制，无法完全发挥主动控制的优点，让引擎与变速器随时保持在最佳的匹配状态，同时顾及加速性能与燃油消耗，所以本文主要研究机车用电子控制式无段变速系统(Electronically Controlled Continuously Variable Transmission， ECVT)最佳换档规划，利用马达与动力螺杆，将旋转运动改变为直线运动，以推动主动滑轮达到改变减速比；分析传统CVT减速比换档曲线与最佳化曲线之加速性能及燃油消耗比较，使引擎能够保持较高性能输出或较低油耗区间运转。
