Abstract
The invention discloses a kind of power assist vehicle velocity response formula power assist control method, for power assist vehicle technical field, it is based on original velocity response formula power assist control method, measure the gradient on road surface in real time by increasing obliquity sensor, inputted using the output of obliquity sensor as the compensation of system, so that system possesses the ability that different power-assisted outputs are realized under identical speed and different road conditions that original velocity response formula power assist control method does not possess, it optimizes power-assisted, lifting customer experience/experience of riding.
Description
Technical field
The present invention relates to electric driving-aid two-wheel car technical field, more particularly to a kind of power assist vehicle velocity response formula Power assisted control
Method.
Background technology
Existing power assist vehicle, which is used, mainly two ways：One is torque induction type, and this mode is mainly by torque
Sensor sensing ride people pedalling force size control moment motor output torque, in high, medium and low speed all the time according to certain
Assist rate output, experience of riding is preferable, but cost is higher；Two be velocity response formula, and this mode mainly leans on revolution speed sensing
The output speed of the common brushless buncher of stepping frequency control of device sensing bicyclist, it is characterized in that the size and speed of power-assisted
Positive correlation, if that must improve assist rate setting if the power-assisted output for increasing upward slope chronic states, but this can bring level road to go slowly
When preshoot sense and step on empty sense when riding at a high speed, otherwise powerlessness when going up a slope chronic can be brought again, this mode is difficult simultaneous
The experience of riding under high, low speed and different road conditions is turned round and look at, but due to low cost, is used widely on low side power assist vehicle.
The content of the invention
The main technical problem to be solved in the present invention is to provide a kind of power assist vehicle velocity response formula power assist control method, its
Optimize power-assisted, lift customer experience.
In order to solve the above technical problems, the present invention provides a kind of power assist vehicle velocity response formula power assist control method, based on speed
Spend induction type power assist control method；It increases the gradient for setting obliquity sensor to measure road surface in real time；Pass through obliquity sensor
Measure inclination degree, and using measurement result as compensation rate and velocity sensor output quantity collective effect in drive and control of electric machine
Device.So that system possesses the ability that different power-assisted outputs are realized under identical speed and different road conditions.
It is described using measurement result as compensation rate and velocity sensor output quantity collective effect in motor drive controller, tool
Body：When measurement result is that then expanded motor is exported uphill angle, when measurement result is that upper lower angle then reduces motor output, incline
Slope angle is more big, increase/reduction amplitude is bigger.
The obliquity sensor is electronic type obliquity sensor.
After the obliquity sensor is arranged on the power assist vehicle, it senses two-wheeled of the direction perpendicular to the power assist vehicle
Line between axle center.
The motor drive controller includes：Voltage-controlled type motor driver and frequency-control-type motor driver.
When the motor drive controller is voltage-controlled type motor driver, it is by integrating circuit by speed probe
The square wave model of output is converted to voltage output uX, obliquity sensor output uy is multiplied with uX by multiplier after being compensated
Control voltage uo, pass through the output of uo controlled motor drivers.
When the motor drive controller is frequency-control-type motor driver；It is passed through using obliquity sensor output uy
Voltage-controlled FM circuit change speed probe output ω X frequency be compensated after control signal ω o, pass through ω o control electricity
The output of machine driver.
For velocity response formula power assist control method, by introducing the compensation rate that road slope value is inputted as system, reach
The effect more consistent with user's impression is more smoothed out in different road conditions and friction speed to the power-assisted of power assist vehicle is exported.
The beneficial effects of the invention are as follows：A kind of power assist vehicle velocity response formula power assist control method, it is based on original speed
Induction type power assist control method, the gradient on road surface is measured by increasing obliquity sensor in real time, with the output of obliquity sensor
Inputted as the compensation of system so that system possess that original velocity response formula power assist control method do not possess in identical speed
With the ability that different power-assisted outputs are realized under different road conditions, it optimizes power-assisted, lifting customer experience/experience of riding.

Embodiment
The present invention is described in further detail below by embodiment combination accompanying drawing.
It refer to shown in Fig. 1, a kind of velocity response formula power assist control method, based on velocity response formula power assist control method,
Characterized in that, increase obliquity sensor measures the gradient on road surface in real time；Inclination degree is measured by obliquity sensor, and
Using measurement result as compensation rate and velocity sensor output quantity collective effect in motor drive controller.So that system possesses
What original velocity response formula power assist control method did not possessed realizes the energy of different power-assisted outputs under identical speed and different road conditions
Power.We can also be referred to as gradient compensation.
It is described using measurement result as compensation rate and velocity sensor output quantity collective effect in motor drive controller, tool
Body：When measurement result is that then expanded motor is exported uphill angle, when measurement result is that upper lower angle then reduces motor output, incline
Slope angle is more big, increase/reduction amplitude is bigger.
The obliquity sensor is electronic type obliquity sensor.
After the obliquity sensor is arranged on the power assist vehicle, it senses two-wheeled of the direction perpendicular to the power assist vehicle
Line between axle center.
In practical application, motor drive controller has been generally included：Voltage-controlled type motor driver and frequency-control-type
Motor driver.
As shown in Fig. 2 implementation one:
For voltage-controlled type motor driver, pass through integrating circuit（It is not limited to）The square wave model that speed probe is exported turns
Voltage output uX is changed to, passes through multiplier（It is not limited to）The obliquity sensor output uy controls after being compensated that are multiplied with uX is electric
Uo is pressed, by the output of uo controlled motor drivers, so that realize improves velocity response formula Power assisted control by gradient compensation
Power-assisted output effect and ride experience, concrete principle.
As shown in figure 3, implementation two:
For frequency-control-type motor driver, export uy using obliquity sensor and pass through voltage-controlled FM circuit change revolution speed sensing
