Digital signal in above-mentioned pattern function includes the content of IA and IB, and digital signal is again the function of IA and IB.Digital signal=fIA, IB.
The calculating of above-mentioned pattern function is: first in pattern function holder 11, remove to select pattern function corresponding to ID value by shift signal ID value, the value of ID does not participate in pattern function and calculates, then in the pattern function input IA > IB difference model data handler 7 and IA < IB difference model data handler 8 of ID being selected, select the some difference model data handlers in IA > IB difference model data handler 7 or IA < IB difference model data handler 8 according to vector, with the vector of the first module, digital signal n, IAn or IBn, add in the some difference model data handlers of ISn substitution and calculate y IAnISn and y IBnISn.Y IAnISn and y IBnISn are last for controlling the original data of former and later two motors of morpet.
Shift signal ID does not participate in the calculating of pattern function like this, but has selected pattern function with shift signal ID,, in the result of calculation of pattern function, has shift signal ID key element, and ID is also the variable of pattern function.So more easily set up pattern function, computation speed is faster, is more conducive to mobile morpet to make in good time front and back wheel power configuration.
The 3rd module: the input end of data distributor 10 is connected with IA > IB difference model data handler 7 and IA < IB difference model data handler 8 respectively, the mouth of data distributor 10 is connected with D and A converter 16, and the mouth of D and A converter 16 is connected with strong power controller A and strong power controller B respectively; Realize the object of difference controller to strong power controller A and strong power controller B control.
Its effect is; The y IAnISn of control data in groups and y IBnISn that data distributor 10 is inputted IA > IB difference model data handler 7 distribute to respectively strong power controller A and strong power controller B, or the y IAnISn of control data in groups and y IBnISn that IA < IB difference model data handler 8 is inputted distribute to respectively strong power controller A and strong power controller B, be that y IAnISn distributes to strong power controller A, y IBnISn distributes to strong power controller B; D and A converter 16 is carried out respectively digital to analogy conversion the digital signal y IAnISn and the y IBnISn that distribute control object, digital signal is converted to the control voltage signal that strong power controller A and strong power controller B can use, finally control voltage signals these two and send two corresponding strong power controllers to.
Realize the shift signal ID of shift signal manual mode controller 3, the car average rate signal IS of average rate device 20, feedback control signal electric current I A and feedback control signal electric current I B carry out the difference control of regulation pattern function to strong power controller A and strong power controller B by difference controller, when reaching front and back wheel and being subject to force unbalance, also can make the power of front and back wheel can keep matchingly within the scope of gear that ID specifies, with IS average uniform velocity pointed, both made respectively two motors power to front and back wheel output matching respectively, reach the front and back wheel object that average uniform velocity is travelled reposefully of morpet.
Control in groups data y IAnISn and y IBnISn and contain that shift signal ID, car average rate signal IS, feedback control signal electric current I A and feedback control signal electric current I B calculate through pattern function, there is this morpet to travel gear, speed state to the integrated demand of powering, although front and back wheel different stressed variations in a flash in other words, but car can also keep original speed as far as possible, the speed of a motor vehicle can be steadily like this.
General trailing wheel is stressed many, and power supply is many, and front-wheel is stressed few, and power supply is few.For different car average rates, the difference size of powering how many is different again, so want ID, IS, IA and tetra-of IB to control former key element.The weight of people on morpet is constant, certain wheel of front-wheel or trailing wheel is stressed when large, power consumption electric current can increase at once, feedback control signal electric current also increases at once, the former difference relation of IA and IB is changed, new ID, IS, tetra-of IA and IB control former key element input difference control boosted vehicle system, difference control boosted vehicle system process controls with these four the pattern function calculating that former key elements match, two of matching with these four controlling elements of output control voltage signals respectively to the motor of front-wheel and trailing wheel, even if make wheel A and wheel B stressed unequal, also can obtain the work of two motor couplings, two wheel balance motions, the effect that morpet held stationary speed is travelled.
Due to different electric controller A and strong power controller B, require the control voltage signal of different voltage ranges, D and A converter 16 is exactly according to different electric controller A and strong power controller B, and digital signal is converted to the control voltage signal that strong power controller A and strong power controller B can use.So D and A converter 16 is indispensable.

The leading rotational angle of bicycle substantially can representative at the bicycle state stable in whether, if leading rotational angle has rotated the angles of 80 degree to 90 degree while comparing just forward, bicycle is in unstable motoring condition, at this moment feedback control signal electric current I A and IB are no matter be any signal, can not, again to motor power supply, must stop immediately motor to power.If leading rotational angle has rotated the angles of 30 degree to 80 degree than just forward time, feedback control signal electric current I A and IB require increasing the delivery that reduce motor with leading rotational angle to motor power supply.General leading rotational angle is at 0 degree during to the angle of 30 degree, and bicycle is that feedback control signal electric current I A and IB require can be completely according to execution to the delivery of motor, do not need to revise in completely normal motoring condition.
For the speed of a motor vehicle that differential distributing box 1 controls and cyclist's body weight are matched, namely, under the condition of the same group of feedback control signal electric current I A changing and feedback control signal electric current I B, two control voltage signals that differential distributing box 1 is exported can change with cyclist's body weight is different.To match with 50 kilograms of body weights as controlled voltage signal with former two of should export of differential distributing box 1, in the time that cyclist's body weight is 40 kilograms, control voltage signal and all reduce 20% for two of the 1 actual output of differential distributing box, or in the time that cyclist's body weight is 70 kilograms, controls voltage signal and all reduce 40% for two of the 1 actual output of differential distributing box.Reaching the speed of a motor vehicle that differential distributing box 1 controls and cyclist's body weight matches.For achieving this end technical scheme be: on the human body cushion of morpet, or on the elastomeric element being connected with cushion, pressure sensor is set, this pressure sensor is connected with the data distributor 10 in differential distributing box 1, the pressure signal of pressure sensor respectively in data distributor 10 two control voltage signal and carry out the processing that same ratio increase or same ratio reduce.
Advantage of the present utility model: differential distributing box of the present utility model can carry out the processing of digital model function to car average rate signal IS, feedback control signal electric current I A and the feedback control signal electric current I B of the shift signal ID of shift signal manual mode controller, average rate device, to will control two controlled things, two motors of front and back wheel of morpet carry out differential control power supply, and the content of differential control is exactly the pattern function processing of setting in advance.Namely differential distributing box Neng Dui tetra-road analog current signals of the present utility model carry out pattern function and are processed into the independently voltage control signal output respectively of differential two-way, can Dui Si road analog signal add digital model function content, two motors of front and back wheel are distinguished and independently controlled power supply, also claim difference control power supply.The work of two motor couplings of front and back wheel, both the strained condition that front and back wheel changes, two motors of front and back wheel mate to from different power supply, reach front and back wheel velocity of rotation identical, and be to make morpet substantially keep being limited within the scope of gear by ID, form the state of the average velociity of IS.The people who rides on this morpet feels comfortably cool, the identical electric power of not wasting again of front and back wheel velocity of rotation.
In pattern function holder, select to be applicable at first the pattern function of ID value by the shift signal ID value of shift signal manual mode controller, under identical IA and IB condition, the gear difference that morpet travels, the control power-assisted effect difference of last difference control boosted vehicle system output.Car average rate signal IS participates in pattern function and calculates, and makes the control signal of last output the speed of a motor vehicle can be controlled to the average velociity that produces IS.Even speed of a motor vehicle held stationary.
The utility model difference control boosted vehicle system is through ID, IS, IA and IB and these four the pattern function calculating that the former key element of control matches, output is controlled former key elements match two and is controlled voltage signals respectively to the motor of front-wheel and trailing wheel with these four, even if make wheel A and wheel B stressed unequal, also can obtain the work of two motor couplings, the effect of two wheel balance motions.
In the case of tetra-of identical ID, IS, IA and IB control former key elements identical, as long as change the digital model function of setting, just can obtain the different control signal outputs of multiple artificial setting, solve by IA and directly two analog electronics of control of two analog signals of IB, only have a kind of mode, can not adjust by human needs the shortcoming of mode.
Can infer the bicycle state stable in whether with leading rotational angle, and by the size of leading rotational angle, feedback control signal electric current I A and the desired difference delivery of IB that cycle racing state is produced are revised, to ensure in the time that bicycle plays pendulum, no longer bicycle is increased to labile factor, use morpet of the present invention more humane, safer.
