    • An automatic gear shift system is provided for an E-bicycle that maximizes the contribution of the electric motor assist of the bicycle while minimizing the instances in which the electric motor assist is invoked. A control system monitors several sensors and particularly the change in sensor data at discrete intervals. If the change in certain sensor data exceeds predetermined thresholds the control system directs an electronic shifting device to execute an upshift or downshift of the bicycle's gearing, as appropriate for the conditions. The control system also determines whether additional thresholds are exceeded, in which case the control system activated the electric motor to assist the rider.
    • 为自行车提供了一种自动换档系统,其使得自动电动机的助力的贡献最大化,同时最小化调用电动机辅助的情况。 一个控制系统监控几个传感器,特别是以离散的间隔改变传感器数据。 如果某些传感器数据的变化超过预定阈值,则控制系统根据条件指示电子换档装置执行自行车传动装置的升档或降档。 控制系统还确定是否超出附加阈值,在这种情况下,控制系统激活电动机以辅助骑手。
