    • Apparatus and method for controlling an electric motor (50) providing assistance to a bicycle rider based on measuring the mechanical power generated by the rider. The power generated by the rider is measured by measuring tension in a bicycle chain (34) (or belt) and RPM. A chain (or belt) roller (14) is carried at the free end of a cantilevered beam (16) and the chain (34) (or belt) rides over the roller (14). The resulting deflection of the cantilevered beam (16) provides a measurement of chain tension. A control signal for the electric motor (50) is generated based on a smoother version of the power generated by the rider.
    • 基于测量骑车人产生的机械动力来控制向自行车骑行者提供辅助的电动机(50)的设备和方法。 骑车人产生的动力是通过测量自行车链条(34)(或皮带)和RPM中的张力来测量的。 在悬臂梁(16)的自由端携带链条(或带)辊(14),并且链条(34)(或带)骑跨在辊(14)上。 所产生的悬臂梁(16)的偏转提供链条张力的测量。 电动机(50)的控制信号是基于驾驶者产生的功率的更平滑版本而产生的。
