Accompanying drawing 2 is system charts that the manpower-electric power of " manpower-electric power is made a concerted effort " of the present invention electronic control system moves with joint efforts;
Accompanying drawing 3 is that " manpower-electric power is made a concerted effort " of the present invention electronic control system changes the all-electric system chart of riding over to;
Prior art has drawn such data, that is, when bicycle was generally ridden under level land, Wu Po, low wind speed, about 12 kilometers/hour of best moving velocity (be manpower when travelling the comparatively comfortable speed of bicyclist) was on average pedaled the about 35Kg-f of power; Surpass 12 kilometers/hour at upward slope, contrary wind or moving velocity, on average pedal the about 65Kg-f of power; Along with the gradient increases or wind-force increase against the wind, increase comparatively difficulty of the power of pedaling, electronic control system is devoted oneself to work and based on electric power, manpower is auxilliary at this moment, can to make " manpower-electric power is made a concerted effort " by key master cock 2.
It is by pedaling on the power position in the maximum in the step of Electrical Bicycle that Electrical Bicycle of the present invention is used one of embodiment of " manpower-electric power is made a concerted effort " electronic control system (EAS), be equipped with one and pedal force gauge, will pedal force signal and input to the EAS system.
When the power of pedaling exceeds setting value, during as 35Kg-f or littler setting value, the EAS system just starts working, and pedaling of bicyclist is tried hard to keep be held on the setting value.
Improve riding speed as needs, need only make electrical motor (actuator) 1 increase horsepower input, just can improve riding speed, about 24 kilometers/hour up to maximum riding speed by the speed regulator 4 of electronic system.
The great advantage of Electrical Bicycle of the present invention " manpower-electric power is made a concerted effort " electronic control system is that bicyclist's the power of pedaling can be given arbitrarily with each one muscle power, the bicyclist is ridden under the state of the power of economizing most, electrical motor 1-battery 5 then available power, in 24 kilometers/hour of moving velocitys, no matter go up a slope, all keep about 24 kilometers/hour running velocity against the wind.
Electrical Bicycle of the present invention also can be installed a speed sensor with another embodiment of " manpower-electric power is made a concerted effort " electronic control system on by Electrical Bicycle, speed signal is imported master control unit.Manpower has been ridden about 3 kilometers/hour (can be given arbitrarily by the bicyclist), and the EAS system just starts working, and electrical motor 1 puts into operation, and quickens the given speed of EAS system.
As regulating arbitrarily in 3-24 kilometer/hour scope, the bicyclist need only just can control 24 kilometers/hour to the Electrical Bicycle manpower given minimum riding speed value of riding with interior moving velocity by the EAS system.
Adopt the EAS system, can make the once electrically-charged operating range of Electrical Bicycle, improve more than 50%, the electrokinetic cell capacity 10AH of battery-driven car for example, 20 kilometers of moving velocitys/time, 30 kilometers of the operating ranges of charging, be equipped with the EAS system after, operating range can be brought up to 60 kilometers, and can see on telltale 3 that the driving magnitude of current significantly descends.
Manpower-the electric power of " manpower-electric power is made a concerted effort " of the present invention electronic control system is the system chart example such as the accompanying drawing 2 of operation with joint efforts.
When riding, the cyclist steps on movable sprocket, speed sensor can be with speed signal conversion or a certain size drive signal, make electrical motor 1 obtain certain electric power supply by having set at least two class in electronic controller 2 circuits, preferred three retainings, along with the increase of riding speed, the electric weight that corresponding increase is supplied with.If cyclist's pin is not stepped on movable sprocket 6, then speed sensor no signal output is just electrical motor 1 can not get electric power supply.
That is to say that want electrical motor to produce drive torque, then the cyclist must step on movable sprocket 6.
Because the power of driving Electrical Bicycle of the present invention has two sources (manpower+electrokinetic cell 5), so distance that power battery charging once travels and time are length than all-electric travelling.
No matter be to be provided with to pedal force gauge or speed sensor, technical characterictic of the present invention is different from the simple merging of manpower of the prior art and electric power, because simple merging of the prior art or use full electric power, so, just can't utilize the comfortable work done of manpower under the low power consuming situation, if simply driven by power is set several class, also electric power and manpower can't be adjusted to the degree of mating most to the contribution of the power of bicycle, and, when needs slow down, the merit that electric power or manpower are done just is wasted, and system of the present invention considers above-mentioned various situation and proposes.
