The invention relates to a gear shifting system and method of an electric motorcycle, the gear shifting system of the electric motorcycle comprises a throttle valve position sensor (TPS), a motor controller and a whole vehicle controller, the throttle valve position sensor senses an accelerator opening degree to generate an accelerator opening degree signal, and the motor controller is connected with the whole vehicle controller. The motor controller receives a motor rotating speed signal representing a motor actual rotating speed of the motor, and the vehicle control unit receives the accelerator opening degree signal and the motor rotating speed signal and calculates an average accelerator change rate according to the accelerator opening degree signal. When the electric motorcycle is in the second gear and the average accelerator change rate meets a preset threshold value in an acceleration correction condition, the vehicle control unit outputs a gear shifting instruction to control the electric motorcycle to be switched from the second gear to the first gear, and the electric motorcycle has the good acceleration performance.

    本发明为一种电动摩托车的档位变换系统及方法,该电动摩托车的档位变换系统包含一节流阀位置感知器(TPS)、一马达控制器及一整车控制器,该节流阀位置感知器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,其中,该整车控制器接收该油门开度讯号及该马达转速讯号并且根据该油门开度讯号计算出一平均油门变化率,在电动摩托车处于二档且该平均油门变化率符合一加速补正条件中的预设门槛值时,该整车控制器输出一换档指令以控制该电动摩托车由二档降至一档,令电动摩托车具有较佳的加速性能。
