Can be divided into two classes by the type of drive Electrical Bicycle.One class is a battery-driven car, and promptly the bicyclist does not need oneself firmly, as long as energized, the motor on the Electrical Bicycle can be worked and be driven bicycle running.This vehicle power derives from storage battery fully, and conventional electric bike battery once charges and can only travel 30～50 kilometers, and frequent charge makes the service life of battery generally less than 1 year.This causes battery-driven car inconvenience in use, and use cost is higher.
Another kind of is the foot-operated two electric assisted bicycles that drive of electric power and manpower, this car collection manpower and electric power are one, between battery-driven car and bicycle, motor provided power-assisted when the bicyclist exerted oneself treadmill, and the size of manpower is passed to computer chip in the controller by a torque sensor, by the output torque of computer chip control motor, power-assisted and manpower are in direct ratio, manpower is big more, and power-assisted is big more, and the not afterburning then motor of bicyclist is not worked.This vehicle has certain energy-saving effect when going up a slope by bike, but generally speaking, energy-conservation not remarkable.Because battery-driven car is when smooth road traveling, the people does not need bigger additional power-assisted, but motor still exports and the corresponding power-assisted of manpower, not only wastes the energy of storage battery, but also may cause the unsafe condition of driving over the speed limit.
Need at present that energy resource consumption is few in a kind of the travelling, once the stroke that charges is long, the electric assisted bicycle that use cost is low and safe and reliable badly.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of easy to use, cost is low, the stroke that once charges is long, energy-conservation Intellectualized electric assisted bicycle.
The technical scheme that realizes the foregoing invention purpose is: a kind of Intellectualized electric assisted bicycle, electric booster system comprise storage battery, controller, digital sensor, DC machine and foot-operated, wherein,
Described digital sensor, it and motor coaxle are used for comprising to the transmission of digital dynamic force moment signal processing circuit the dynamic digital impulse singla of real-time moment dynamic-change information and velocity information;
Be provided with in the described controller:
The reference velocity digital signal generator is used to set the standard digital speed pulse signal of described DC motor, and with this impulse singla as exporting to dynamic digital torque signals treatment circuit with reference to digital speed pulse signal;

In sum, adopt digital moment/voltage close loop control among the present invention in the electric power assisted control system, by the dynamic change of the detected Real Time Drive moment of the digital position transducer that is installed in axis or other region of interest, the digital dynamic force moment signal processing circuit comprehensively obtains comprehensive moment increment signal with real-time dynamic force moment variable signal and reference speed signal then, the last time output torque output signal of comprehensive moment increment signal and motor inversely adds, impulse singla after the stack goes to control the output torque of motor to power inverter, forms a digital dynamic force moment closed loop circuit.This moment, the output torque of motor was relevant with bicyclist's speed, applied moment, increased if manpower applies moment, and comprehensive moment increment increases, and the output torque of motor just reduces.
As a further improvement on the present invention, the present invention also comprises protective circuit, and protective circuit comprises that hypervelocity suppresses circuit, Ultra-Low Speed signal generator and Ultra-Low Speed protective circuit; Hypervelocity suppresses circuit, receive the reference velocity impulse singla that real-time speed impulse singla that described digital sensor sends and reference speed signal send, real-time speed impulse singla and pre-set velocity impulse singla are compared, when real-time speed is higher than pre-set velocity, constantly sends an of short duration pulsewidth and close gate signal to described Digital Logic interface circuit; The Ultra-Low Speed signal generator, default ultralow speed pulse signal; The Ultra-Low Speed protective circuit; receive the ultralow speed pulse signal that real-time speed impulse singla that described digital sensor sends and Ultra-Low Speed signal generator send; real-time speed impulse singla and Ultra-Low Speed impulse singla are compared; when real-time speed is lower than ultralow speed; send pulse and close gate signal to described Digital Logic interface and power amplifier; make not conducting of power tube, when real-time speed increase to surpass ultralow speed, send the pulse enabling signal and give described Digital Logic interface and power amplifier.
