Problems solved by technology

When the rider is pedaling, if he just shifts gears when he is pedaling hard, it will cause the transmission to change the gear ratio and cause the problem of uneven bite, which will affect the riding comfort of the user.

Abstract

The invention relates to an automatic variable speed bicycle with best gear shifting time. The automatic variable speed bicycle comprises a bicycle main body, a power supply module, a microcomputer, a gear shift control driver and a pedal position sensing module, wherein the bicycle main body consists of a crankshaft, two cranks, two pedals and a speed changer; the pedal position sensing module is arranged on the bicycle main body and corresponds to the at least one crank, and by the pedal position sensing module, the swinging angle position of the at least one crank and whether the pedaling direction is forward treaded or reversely treaded can be known; in treading process, the microcomputer can judge the best gear shifting time to be the time point when the at least one crank is positioned at next pedal dead point, or the time when the value of the treading rotating speed is smaller than a preset value of rotating speed, or the time when the reverse treading is carried out.

Description

technical field [0001] The present invention is related to an automatic transmission bicycle, in particular to an automatic transmission bicycle with optimum shifting timing. Background technique [0002] For automatic transmission bicycles, the timing of shifting is mostly based on the vehicle speed and pedaling speed. At present, there is no technology for judging the timing of shifting according to the pedaling angle of the user. When the rider is pedaling, if he just shifts gears when stepping heavily, it will cause the transmission to change the gear ratio and cause the problem of uneven bite, which will affect the riding comfort of the user. Therefore, if the rider can select the opportunity to shift gears when stepping lightly, the gear shifting can be made smoother and the riding comfort can be improved. [0003] However, the shifting of the bicycle must be under the condition of being pedaled. Therefore, if the timing of shifting is to be judged according to the pe...
