Background technology
At present, the electronic transmission of electric bicycle is all independent not have any relation with the controller on car, have
When the foot of people steps on torque when speed change or to step on frequency very high, at this time have very big power that speed change can be caused difficult on chain,
System motor output torque is particularly put in current trend to be applied directly on chain, makes speed change more difficult, some road conditions
Power during as climbing on chain is also very big, at this moment if we speed change may damage speed changer or chain by force.
Utility model content
The utility model aim is：In view of the above-mentioned problems, providing a kind of speed change management system for electric bicycle, carry
Height is ridden experience.
The technical solution of the utility model is：
A kind of speed change management system for electric bicycle, including electric machine controller and connected speed change is defeated respectively
Enter device, electronic transmission, assistant sensor, the speed change input unit sends gear-shift command signal to electric machine controller, helps
Force snesor gathers the power-assisted signal of electric car, and electric machine controller controls electronic transmission shifting time according to power-assisted signal.
Preferably, the power-assisted signal of the assistant sensor collection electric car includes stepping on frequency signal.
Preferably, the power-assisted signal of the assistant sensor collection electric car further includes torque signals.
Preferably, the assistant sensor sends power-assisted signal through but not limited to serial ports or CAN to electric machine controller.
Preferably, the electric car of assistant sensor collection steps on frequency signal and when torque signals meets the threshold value of setting,
Electric machine controller controls electronic transmission speed change, otherwise not speed change.
Preferably, the speed change input unit uses selector button.
Preferably, the electric car uses built-in motor, and electric machine controller reduces accordingly when receiving gear-shift command signal
Motor exports, and motor recovers normal output after the completion of speed change.
The utility model has the advantages that：
1. the utility model provides speed change management system, electric machine controller controls electronic transmission to become according to power-assisted signal
The fast time, speed changer is just controlled when only power-assisted signal is smaller, user's speed change during cycling is easier to greatly improve
Ride experience.
2. the utility model provides speed change management system, the stress in speed-change process on chain and electronic transmission is very

Embodiment
Embodiment 1
As illustrated in fig. 1 and 2, the speed change management system described in the utility model for electric bicycle, including motor control
Device processed and respectively connected selector button, electronic transmission, assistant sensor, further include the electricity for above-mentioned each component power supply
Source.The selector button to electric machine controller send gear-shift command signal, assistant sensor collection electric car step on frequency signal and
Torque signals, and by serial ports or CAN bus to electric machine controller is sent to, electric machine controller is frequently big with torque according to stepping on
It is small, control electronic transmission shifting time.
As shown in figure 3, during utility model works, electric machine controller constantly detect selector button variable rate signal and
Assistant sensor signal steps on frequency, torque signals.When no variable rate signal comes, controller control speed changer is failure to actuate；When there is change
When fast signal comes, electric machine controller can detect the torsion signal of assistant sensor and step on frequency signal at once, as torsion T and step on frequency f
It is in respectively in the shaded region of Fig. 4 and Fig. 5, i.e. when T1≤T≤T2, f1≤f≤f2, electric machine controller can send speed change and refer to
Make to speed changer, realize steady speed change.
Embodiment 2
Above-mentioned implementation process is the electric bicycle for moment of torsion type, for the electric car of velocity profile, due to Motor torque
It is smaller, can be without considering torsion signal in implementation process.Therefore, assistant sensor no longer gathers the torque signals of electric car.When
When having the variable rate signal, only detection assistant sensor steps on frequency signal inside electric machine controller, when the shade for stepping on frequency f and being in Fig. 5
In the range of, i.e. during f1≤f≤f2, electric machine controller can send gear-shift command to speed changer, realize steady speed change.
, can also phase when at this moment controller obtains variable rate signal when it is implemented, some electric cars use built-in motor
The reduction motor answered exports, and motor normally exports after the completion of speed change.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
People can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this.It is all
The modification done according to the Spirit Essence of the utility model main technical schemes, should all cover in the scope of protection of the utility model
Within.
