Abstract

A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing.

Description

[0001] divisional application [0002] This application is a divisional application of an invention patent application with the application number 202010091160.7, the application date is February 13, 2020, and the invention name is a shift system for human-powered vehicles. Background technique [0003] Many human powered vehicles such as bicycles include the ability to shift gears. If the rider of such a vehicle enters a gear change command at the wrong time for the shift, the ideal shift point on the sprocket may be missed. In this case, shift shock may occur and cause discomfort to the rider. While very experienced cyclists can develop skills for timing gear changes to avoid shift shock, many other cyclists lack such skills. Contents of the invention [0004] According to a first aspect of the invention, a gear shifting system for a man-powered vehicle includes a controller. The controller is configured to receive drive torque and cadence of the human powered vehicle ...
