SYSTEM AND METHOD FOR CONTROLLING A TRANSMISSION OF A HUMAN-POWERED VEHICLE

摘要

This system creates a virtual image of the user's entire operating environment using a combination of hub speed, crank speed, inclination, and acceleration measurements. With this information, the system is able to understand the output torque and speed, and through control of the transmission, change the“gear ratio”to achieve a more desired operating condition based on the individual user's preferences. In addition, this system is designed to also work with a continuously variable transmission to avoid the shortfall of the state of the art systems, which can only get within a wide range of the optimal cadence because of the fixed ratios of a derailleur system.
