Brief description of the drawings
Fig. 1 is the exploded view of automatic transimission of the present invention.
Embodiment
The present invention is described in more detail with reference to the accompanying drawings and examples.
The invention discloses a kind of automatic gear shifting method for multi-speed bicycle, including upward slope pattern, upward slope pattern bag
Two or more gearshift mechanism are included, different gearshift mechanism corresponds to corresponding gear shift area according to the gradient size of upward slope
Between, the gradient is bigger, and the gear of gearshift is lower.
On the basis of such scheme, in addition to upward slope pattern starting step, the upward slope pattern starting step include：
Step S1, self study sets the threshold value A of uphill angle；
Step S2, when angular transducer senses that the angle change of car body exceedes the threshold value of uphill angle, upward slope mould is started
Formula.
Automatic speed-changing bicycle is put on a horizontal ground or the ground with certain slope, then we pass through
One entrance (such as pressing a button) allows the lower level of micro-control unit MCU meter records to strengthen state or gradient state lower angle sensor
Data A and preserve, then when actually riding, data that micro-control unit MCU is measured in real time and this angular transducer are pre-
The data A deposited is compared, and determines whether to start upward slope pattern.Meanwhile user can be with according to ride custom and the muscle power controlled oneself
Control oneself and the data A that prestores of angular transducer be set, can obtain preferably, be suitable for the experience of riding of oneself.
Specifically, angular transducer senses that the angle change of car body exceedes the duration of uphill angle threshold value more than 500ms
When, start upward slope pattern.On the ground with hollow, the angle change of car body is instantaneously completing and rapid can reply
To original state, the actual change for the gradient of not riding, if also carrying out upward slope pattern in angle transient change
Start, then useless switching can frequently occur, can not only influence the experience ridden, can also influence the life-span of gearshift.
Preferably, upward slope pattern include three gearshift mechanism, when car body angle exceed threshold value A+1 but less than A+2 degree it
Between when, gearshift gear be limited to the 4th grade；When the angle of car body is more than A+2 degree but less than or equal between A+3 degree, shelves of shifting gears
Position is limited to the 2nd grade；When the angle of car body is spent more than A+3, gearshift gear is limited to the 1st grade.So that threshold value A is 2 degree as an example, when
When the angle of car body is more than 3 degree but less than between 4 degree, the lowest gear of gearshift is the 4th grade；When car body angle more than 4 degree but
When between less than or equal to 5 degree, the lowest gear of gearshift is the 2nd grade；When the angle of car body is more than 5 degree, the deep low gear of gearshift
Position is the 1st grade.
Preferably, in addition to level road pattern, when the angle of car body equals or exceeds threshold value A degree but less than between A+1 degree
It is considered as level road pattern, the gearshift gear of the level road pattern is limited to default gear.For example in level road pattern, gearshift is most
Low-grade location can be limited to 6 grades, 7 grades or 8 grades.
Specifically, when switching between different stalls, 500ms duration is exceeded into the angular interval corresponding to new gear
The switching of new gear is just carried out afterwards.On the ground with hollow, the angle change of car body is instantaneously completing and fast
Speed can be returned to original state, the actual change for the gradient of not riding, if also carried out in angle transient change new
The switching of gear, then useless switching can frequently occur, and can not only influence the experience ridden, and can also influence the longevity of gearshift
Life.
Specifically, also including upward slope pattern switching descending pattern, the upward slope pattern switching descending pattern includes following step
Suddenly：
Angular transducer senses that the angle change of car body is become by uphill angle and turns to the lasting default duration of descending angle
And when speed meets or exceeds default velocity amplitude, gear by 1 grade, 2 grades, 3 grades or 4 grades of low speed jump to 6 grades, 7 grades, 8 grades,
9 grades, 10 grades or 11 grades, it is considered as lower angle of slope when the angle of car body is spent less than threshold value A.
Preferably, angular transducer senses that the angle change of car body turns to descending angle duration by uphill angle change and exceeded
2 seconds and speed meet or exceed 18 kilometers per hour, and any one gear of gear in 1 grade, 2 grades or 3 grades is leapt to
8th grade, to eliminate influence caused by torque diminishes suddenly.
