Detailed description of the invention
As in figure 2 it is shown, the method being automatically adjusted throttle on distance increasing unit of the present invention, use monitoring automatically and control system
System realizes, and voltage battery tension and electromotor produced is obtained by sample circuit and sends CPU to, and voltage signal exists
Processing in CPU, then realize the open out of electromotor by controlling motor and subtract throttle, driver has only to control to increase
Journey device switch motion.Automatically monitoring and control system include that battery tension selects module, electromotor voltage filter module, stepping
Motor control module and protection module.
The working method of each module described further below.
Battery tension selects module
Because the storage battery performance of the relation of battery technology, different brands and model is different, there is also full electricity short of electricity etc. simultaneously
Different duties, more preferably reaches the purpose of voltage stabilizing for control system, can whole working stage is continuous must be to storage battery shape
State judges, selects module to choose the corresponding parameter that calculates by battery tension and participates in calculating.
As it is shown on figure 3, implementation is as follows: after monitoring and control system are started working automatically, control system sends
Voltage test signal, by AD sampling module read voltage information, then judges information of voltage, from controller
Reading out corresponding voltage in FLASH and calculate parameter, including by high pressure thresholding, low pressure thresholding quickly calculates voltage range,
By the starting current upper limit, the charging current upper limit quickly calculates speed threshold, the rotating speed protection upper limit, and calculates motor
Adjustable calculation coefficient.
Read from controller and calculate parameter accordingly.Including following:
Reference voltage: as controlling benchmark, the generated energy that throttle is adjusted to distance increasing unit is equal to reference voltage, by hardware electricity
Road sampling obtains, and reference voltage=set of cells model (48V/60V/72V) * downsampling factor (hardware circuit decision)+calibration value is (hard
Part device error).
High pressure thresholding, ratio high-pressure door limit for height, exceed the deviation value of generated energy, need comparatively fast to adjust motor, high
Pressure gate limits=protects voltage (such as 63V) * downsampling factor+calibration value；.
Low pressure thresholding, higher than low pressure thresholding, exceed the deviation value of generated energy, need comparatively fast to adjust motor.Low
Pressure gate limits=protects voltage (such as 56V) * downsampling factor+calibration value.
Quickly calculate voltage range: outside this voltage range, influence whether car duty, motor
Adjustment can be accelerated, and response is more timely, this be generally present in tricycle brake suddenly or suddenly startup stage, quickly calculate electricity
Thresholding=reference voltage ± (high pressure thresholding-low pressure thresholding) (response coefficient is by testing for * response coefficient for pressure scope=quickly calculate
Arrive, more than 1).
The starting current upper limit: determine according to ardware feature, for the current protection effect of electric motor starting, the starting current upper limit
=theoretical current * downsampling factor+calibration value.
The charging current upper limit: in order to protect the life-span of storage battery, the charging current during ZCQ work can not be excessive, by storage battery
Performance determines, the charging current upper limit=theoretical current * downsampling factor+calibration value.
Quickly calculate speed threshold: the generated energy of motor is not linear, process on according to rotating speed be classified as by
Two parts linear process.A part calculates fast, and slope is big, and another part calculates slow, and slope is little.Quickly calculate thresholding=benchmark
Rotating speed (experiment value)+deviation value (is selected by storage battery and power of motor).
Rotating speed protection is upper to be limited: determined by engine model, and the service behaviour exceeding this rotation engines is deteriorated, the life-span
Decline.Determined by engine model.For selective value.
Electromotor voltage filter module
As shown in Figure 4, because the four-stroke mode of operation of electromotor, cause in real work situation, even if throttle is big
Little identical, electromotor rotating speed be not constant, the speed of coil cutting magnetic induction line is the most different, and the voltage of generation is not
Steady state value, it is therefore desirable to voltage is processed.Control system waits that driver sends electromotor working signal, when signal produces
After, the voltage produced by AD thief hatch detection electromotor, sample frequency is motor commutation frequency, by front 300 signals
Calculating, it is judged that the magnetic pole logarithm of motor, determine the filtering parameter of sampled voltage, in the way of glide filter, voltage signal entered
Row calculates.
Step motor control module
Motor uses four phase eight beat control mode.According to the difference of sample voltage value Yu setting voltage, adjust stepping
The position of motor.
Coefficient value N, M are empirical value.
Protection module
The power of distance increasing unit does not mates with the power driving motor, or drives the situation of overload, can make distance increasing unit and electricity
The service life in pond reduces, to this end, be specifically added protection module in the controls, content is respectively rotating speed protection and electric current
Protection；As it is shown in figure 5, rotating speed protection is the rotating speed in order to limit electromotor, electromotor is made to be operated in the region that efficiency is higher.Inspection
Surveying rotating speed, when rotating speed is less than setting more than setting speed and current voltage, control system enters speed limit pattern, is maintained by rotating speed
At maximum speed, detect that magnitude of voltage jumps out speed limit pattern when being more than setting voltage.
As shown in Figure 6, current protection is to limit charging current, makes the charging current of accumulator less than maximum charge electricity
Stream, detects charging current, when charging current is more than maximum charging current, controls to enter current-limit mode, charging current is maintained
At maximum charging current, detect that magnitude of voltage jumps out current-limit mode when being more than setting voltage.
