AI Technical Summary

Technical Problem

Existing human-powered vehicle control devices are difficult to properly control the gear shifting mechanism, resulting in improper increases or decreases in the gear ratio, which affects the rider's load changes and operating experience.

Method used

The control unit of the vehicle control device, driven by human power, controls the transmission to suppress or increase the gear ratio based on the gear change conditions and auxiliary level change conditions. This includes detecting parameters such as vehicle tilt angle, crankshaft speed and driving environment, and using the transmission unit and gearbox to achieve appropriate control of the gear ratio.

Benefits of technology

It enables appropriate control of the gear ratio under different riding conditions, reducing rider discomfort from load changes and improving operational convenience and safety.

Abstract

This invention provides a control device for a manually operated vehicle capable of appropriately controlling a transmission. The manually operated vehicle includes: a transmission configured to change the ratio of the rotational speed of the wheels of the manually operated vehicle to the rotational speed of the crankshaft of the manually operated vehicle, i.e., a gear ratio; and a transmission unit configured to apply a propulsive force to the manually operated vehicle, the transmission unit being configured to change an assist level. The control device for the manually operated vehicle includes a control unit configured to control the transmission, the control unit being configured to control the transmission based on shifting conditions to change the gear ratio, and, when both the assist level change condition and the shifting condition are satisfied, controlling the transmission in a first control state that suppresses an increase in the gear ratio.
