AI Technical Summary

Technical Problem

Existing control devices for manually driven vehicles have difficulty shifting gears properly under changing conditions, especially when the crankshaft stops rotating or is about to stop, in which case the derailleur cannot shift gears effectively.

Method used

By incorporating a motor into the control unit, the control unit can perform speed change operations by driving the transmission through the motor when the crankshaft rotation stops or is about to stop, and control the motor drive according to the predetermined amount of rotation and speed change ratio to ensure that the derailleur can change speeds appropriately.

Benefits of technology

This technology enables the derailleur to continue shifting gears appropriately even when the crankshaft has stopped or is about to stop rotating, reducing power consumption and adjusting the shift ratio according to driving conditions and environment, thus improving the adaptability and efficiency of shifting.

Abstract

This invention provides a control device for a manually operated vehicle that allows for appropriate gear shifting via a derailleur. The control device for the manually operated vehicle includes a control unit. The vehicle includes: a crankshaft; at least one first rotating body; a wheel; at least one second rotating body; a transmission body; a derailleur; and a motor configured to drive the transmission body. The control unit is configured to control the motor and the derailleur, and is configured to drive the transmission body via the motor in at least one of the following situations: after the derailleur shifting operation begins while the crankshaft is rotating and before a predetermined first period has elapsed; and after the derailleur shifting operation begins while the crankshaft is rotating and before a predetermined first period has elapsed, the control unit presumes that the crankshaft's rotation has stopped.
