The invention relates to a constant-speed system and method for a constant-speed downhill electric bicycle, which comprises a control module, a control panel, a battery pack and at least one hub motor/generator, and the control panel is electrically connected with the control module. The hub motor/generator is electrically connected with the control module, and the battery pack is electrically connected with the control module. A target speed is set through the control panel, the control module sets an initial electric energy recovery value according to the target speed, an electric bicycle enters a constant speed control mode, and if the current speed of the electric bicycle is larger than the target speed, the control module gives an electric energy recovery increasing instruction to the hub motor/generator. The hub motor/generator can increase electric energy recovery; or if the current speed is smaller than the target speed, the control module gives an electric energy recovery reduction instruction to the hub motor/generator, so that the hub motor/generator reduces the electric energy recovery.

    本发明为一种定速下坡电动自行车的定速系统及方法,其包含有一控制模块、一控制面板、一电池组与至少一轮毂马达/发电机,控制面板电性连接控制模块。轮毂马达/发电机电性连接控制模块,电池组电性连接控制模块。藉由控制面板设定一目标车速,控制模块依据目标车速,而设定一起始电能回收值,一电动自行车进入一定速控制模式,电动自行车的一当前速度大于目标车速,则控制模块将一增加电能回收指令给予轮毂马达/发电机,以使轮毂马达/发电机增加电能回收;或者当前速度小于目标速度,则控制模块将一降低电能回收指令给予轮毂马达/发电机,以使轮毂马达/发电机降低电能回收。
