The invention discloses a bicycle, an electronic transmission and a low-electric-quantity gear control method thereof.The method comprises the steps that in response to a gear shifting instruction of a user, whether the current state of the electronic transmission is a low-electric-quantity state or not is judged; if the current state of the electronic transmission is a non-low electric quantity state, gear shifting operation is carried out according to the gear shifting instruction; if the current state of the electronic transmission is the low-electric-quantity state, a target gear of the gear shifting instruction is obtained, and whether the target gear is within a preset gear shifting limiting range or not is judged; when the target gear is within a preset gear shifting limiting range, gear shifting operation is carried out according to the target gear; and when the target gear exceeds the preset gear shifting limiting range, the current gear of the electronic transmission is kept. According to the method, low-electric-quantity gear control of the electronic transmission can be achieved, the probability of gear shifting failure under the low electric quantity is reduced, waste of the electric quantity of a battery is avoided, and meanwhile the stability of the battery and the system can be protected.

    本发明公开了一种自行车、电子变速器及其低电量档位控制方法,该方法包括:响应于用户的变档指令,判断所述电子变速器的当前状态是否为低电量状态;若所述电子变速器的当前状态为非低电量状态,则根据所述变档指令进行变档操作;若所述电子变速器的当前状态为低电量状态,则获取所述变档指令的目标档位,并判断所述目标档位是否在预设变档限制范围内;当所述目标档位在预设变档限制范围内时,则根据所述目标档位进行变档操作;当所述目标档位超出预设变档限制范围时,则保持电子变速器的当前档位。本发明能够实现电子变速器的低电量档位控制,降低低电量下换挡失败的概率,以及避免对电池电量的浪费,同时还能对电池和系统的稳定性起到保护作用。
