The invention relates to an automatic gear shifting system of an electric motorcycle and a method thereof, the automatic gear shifting system of the electric motorcycle comprises a throttle valve position sensor, a motor controller, a vehicle control unit and a gear shifting calculation unit, the throttle valve position sensor is used for sensing an accelerator opening degree to generate an accelerator opening degree signal. The motor controller receives a motor rotating speed signal representing the actual rotating speed of the motor, the vehicle control unit receives the accelerator opening degree signal and the motor rotating speed signal, and the gear shifting calculation unit is provided with a downshift critical curve and an upshift critical curve in advance. And the accelerator opening signal and the motor rotating speed signal are compared with the downshift critical curve and the upshift critical curve so as to judge whether to output a shift instruction to control the electric motorcycle to shift.

    本发明为一种电动摩托车的自动换档系统及其方法,该电动摩托车的自动换档系统包含一节流阀位置感知器、一马达控制器、一整车控制器、一档位变换计算单元,该节流阀位置感知器(TPS)感测一油门开度以产生一油门开度讯号,该马达控制器接收代表该马达的一马达实际转速的一马达转速讯号,该整车控制器接收该油门开度讯号及该马达转速讯号,该档位变换计算单元预设有一降档临界曲线及一升档临界曲线,将该油门开度讯号及该马达转速讯号与该降档临界曲线及该升档临界曲线相互比对,以判断是否要输出一换档指令以控制该电动摩托车进行换档。
