Like this, will spend a lot of time before reaching the shift gear that the cyclist wishes to reach, wasted time
Furthermore, since the useless shifting operation is performed, when the electric transmission is used for shifting, power consumption is unnecessary.

[0020] "constitute"
[0021] figure 1 The bicycle 1 provided with the bicycle gearshift control device of the present invention is shown.
[0022] Bicycle 1 is a mountain bike type sports bicycle, which is composed of the following main components: frame 2; front fork 3; handle 4; front wheel 5; rear wheel 6; chain 7; front external transmission device 8; And rear exterior speed change device 9.
[0023] Vehicle frame 2 is the basic part that constitutes bicycle, and front fork 3 is arranged at its front part, and front external gear change device 8 is arranged at the lower part of its center, and rear wheel 6 and rear part external gear change device 9 are arranged at its rear part. In addition, at the upper part of the center of the vehicle frame 2 there is a seat 11 on which a rider sits.
[0024] Front fork 3 is installed in vehicle frame 2 front parts, can rotate freely on the shaft of inclination. A handle 4 is mounted on the top of the front fork 3, and a front whee...

The present invention provides a gear-change control unit for bicycle that conducts appropriate speed change according to a gear-change signal in actuation of speed change. The solution of the present invention is that this gear-change control unit is equipped with gear-change command unit 14b that outputs a gear-change signal for causing the speed of rear sheathing transmission 9 to change and a gear-change control unit 15 to cause a speed of rear sheathing transmission 9 to change, according to the output gear-change signal. The gear-change control unit 15 stores all of one or more gear-change signals that are output from a gear-change command unit 14b during the time after the rear sheathing transmission 9 starts gear-change actuation until its completion, and it measures the gear step, when performing the memorized gear-change signal altogether one by one and actuates the rear sheathing transmission to the final gear step of the result that is measured, after completion of gear-change operation of the transmission.
Description
technical field [0001] The present invention relates to a speed change control device and a speed change control method, in particular to a speed change control device and a control method for a bicycle with a speed change control device mounted on a bicycle and having multiple gears. Background technique [0002] In recent years, bicycles equipped with electric or other variable speed transmission devices have been known. In this gear shifting device, it can be automatically shifted according to the speed, or it can be shifted manually by the cyclist. In this way, according to the speed and the shifting operation, a shifting signal is issued, and according to the outputted shifting signal, the motor is controlled by means of the shifting control section to shift the speed of the shifting device. [0003] There are also those that send out a shift signal during the shifting process. In the past, when a shifting signal was received during the shifting process, the shifting ...
