Embodiment Construction

[0041] According to the present invention, a variable-speed bicycle capable of identifying abnormal conditions includes:

[0042] A bicycle main body with a transmission; a power supply module installed on the bicycle main body; a microcomputer electrically connected to the power supply module and the transmission, the microcomputer stores a gear calibration table, the gear calibration table has vehicle speed, pedal speed, gear position and multiple gear ratios, these gear ratios correspond to different gears respectively, the transmission provides actual gear information to the microcomputer; a shift control driver is electrically connected to the microcomputer, and is controlled by the microcomputer The control of the microcomputer is used to drive the transmission to change speed; and a vehicle speed sensor and a pedal speed sensor are respectively arranged at predetermined positions of the bicycle body and electrically connected to the microcomputer to detect the vehicle sp...

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...
