Variable-speed bicycle capable of identifying unusual conditions and identifying method of bicycle

Abstract

The invention discloses a variable-speed bicycle capable of identifying unusual conditions and an identifying method of the bicycle. The bicycle comprises a transmission on the bicycle, a power supply module, a microcomputer, a gear check table which is stored inside the microcomputer, a gear shifting control driver, a vehicle speed sensor, a treading speed sensor and an alarming device, wherein gear identification is conducted through combination of the assemblies, during identification, the microcomputer obtains a virtual gear ratio through the ratio of the vehicle speed to the treading speed and inquires the gear check table according to actual gear information provided by the transmission to obtain a gear shifting-gear ratio, the microcomputer compares the virtual gear ratio with the gear shifting-gear ratio to determine whether gears are unusual or a chain falls down, and a rider is informed when unusual conditions occur.

Description

technical field [0001] The invention is related to the speed change system of the bicycle, in particular to a speed change bicycle capable of identifying abnormal conditions and an identification method thereof. Background technique [0002] Press, known variable speed bicycle, when the user rides, can't directly know whether the situation that chain comes off chain takes place, must directly observe the occlusal condition of chain with eyes, or judge whether the occlusal of chain is normal by the feeling of stepping on. Moreover, if the foregoing situation occurs, not only the transmission is likely to be damaged, but what is more, the rider may be harmed. [0003] At present, there is no technology that uses the speed of the vehicle and the pedal speed to judge whether the chain is engaged normally, nor does it use the speed of the vehicle and the pedal speed to judge whether the speed change is correct. Contents of the invention [0004] The object of the present inven...

AI Technical Summary

Problems solved by technology

[0002] By the way, with the known variable speed bicycles, the user cannot directly know whether the chain is unchained when riding, and must directly observe the occlusal state of the chain with eyes, or judge whether the occlusion of the chain is normal through the feeling of pedaling

Moreover, if the aforementioned situation occurs, it is not only likely to damage the transmission, but what is more, it may also cause harm to the rider.

[0003] At present, there is no technology to judge whether the chain bite is normal by using the vehicle speed and pedal speed, and there is no technology to judge whether the gear shift is correct by using the vehicle speed and pedal speed
