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 is controlled the difference that strong power controller A and strong power controller B carries out regulation pattern function by difference controller, when reaching front and back wheel by force unbalance, within the scope of the gear that the power of front and back wheel also can be made to keep ID to specify matchingly, with the average uniform velocity pointed by IS, both made two motors respectively to the power of front and back wheel output matching respectively, the front and back wheel reaching morpet is the object that travels of average uniform velocity reposefully.
Control data y IAn and y IBn contains shift signal ID in groups, car average rate signal IS, feedback control signal electric current I A and feedback control signal electric current I B calculate through pattern function, this morpet is had to travel gear, speed state to the integrated demand of power supply, stressedly to change although front and back wheel is different in a flash in other words, but car can also keep original speed as far as possible, such speed of a motor vehicle can be steadily.
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 rate, the difference size of powering how many is different again, so want ID, IS, IA and IB tetra-to control former key element.The weight of people on morpet is constant, front-wheel or certain wheel of trailing wheel stressed large time, power consumption electric current can increase at once, feedback control signal electric current also increases at once, the former difference relationship of IA and IB is changed, new ID, IS, IA and IB tetra-controls former key element input difference and controls boosted vehicle system, difference controls boosted vehicle system through controlling the pattern function that former key element matches calculate with these four, two control figure signals that output and these four controlling elements match give the motor of front-wheel and trailing wheel respectively, even if make wheel A and wheel B stressed unequal, also the work of two motor couplings can be obtained, two wheel balance motions, the effect of morpet held stationary speeds.
Due to different electric controller A and strong power controller B, require the control figure signal of different digital scope, data normalization conv 16 is exactly according to different electric controller A and strong power controller B, and the digital signal calculated is converted to the control figure signal that strong power controller A and strong power controller B can use.So data normalization conv 16 is indispensable.
Can also be, IA > IB difference model data handler 7 is connected with data distributor 10 by corner parameter Processor 30 with IA < IB difference model data handler 8, and corner parameter Processor 30 is also connected with leading rotary angle transmitter 31.
Whether stable the leading rotational angle of bicycle representative can be in state at bicycle substantially, if leading rotational angle is than the angle that have rotated 80 degree to 90 degree time just forward, then bicycle is in unstable motoring condition, at this moment no matter feedback control signal electric current I A and IB is any signal, can not, again to feeding electric motors, must stop feeding electric motors immediately.If leading rotational angle is than the angle that have rotated 30 degree to 80 degree time just forward, feedback control signal electric current I A and IB requires to reduce the delivery to motor to should increasing with leading rotational angle of feeding electric motors.General leading rotational angle is when the angle of 0 degree to 30 degree, and bicycle is in completely normal motoring condition, and feedback control signal electric current I A and IB requires can, completely according to execution, not need to revise to the delivery of motor.
The speed of a motor vehicle controlled to make difference controller 1 and the body weight of cyclist match, namely under the condition of the same group of feedback control signal electric current I A changed and feedback control signal electric current I B, two control figure signals that difference controller 1 exports can change with the body weight difference of cyclist.As being match with 50 kilograms of body weights with former two the control figure signals that should export of difference controller 1, when the body weight of cyclist is 40 kilograms, two control figure signals that difference controller 1 reality exports all reduce 20%, or when the body weight of cyclist is 70 kilograms, two control figure signals that difference controller 1 reality exports all reduce 40%.The body weight reaching the speed of a motor vehicle that difference controller 1 controls and cyclist matches.For achieving this end technical scheme be: on the human body cushion of morpet, or pressure sensor is set on the elastomeric element be connected with cushion, this pressure sensor is connected with the data distributor 10 in difference controller 1, and the pressure signal of pressure sensor carries out to two control figure signals in data distributor 10 process that same ratio increase or same ratio reduce respectively.
Advantage of the present utility model: difference controller of the present utility model can carry out the process of digital model function to car average rate signal IS, the feedback control signal electric current I A and feedback control signal electric current I B of the shift signal ID of shift signal manual mode controller, average rate device, to two controlled things that will control, front and back wheel two motors of morpet carry out differential control power supply, and the content of differential control is exactly the pattern function process of setting in advance.Namely difference controller Neng Dui tetra-road of the present utility model analog current signal carries out pattern function and is processed into differential two-way digital controlled signal independently and exports, digital model function content can be added to four tunnel analog signals, the control that front and back wheel two motors carry out independently is powered, also claims difference to control power supply.The work of front and back wheel two motor couplings, both front and back wheel change strained condition, front and back wheel two motors mate to from different power supplies, reach front and back wheel velocity of rotation identical, and be make morpet substantially keep being limited within the scope of gear by ID, form the state of the average velociity of IS.The people ridden on this morpet feels comfortably cool, the identical not wastes power again of front and back wheel velocity of rotation.
In pattern function holder, the pattern function being applicable to ID value is selected at first by the shift signal ID value of shift signal manual mode controller 3, namely under identical IA and IB condition, the gear that morpet travels is different, and last difference controls the control power-assisted effect difference that boosted vehicle system exports.Car average rate signal IS participates in pattern function and calculates, and the speed of a motor vehicle can be controlled at the average velociity producing IS by the last control signal exported.Even if speed of a motor vehicle held stationary.
The utility model difference controls boosted vehicle system and controls through ID, IS, IA and IB and these four pattern function that former key element matches and calculate, export and to control two control figure signals that former key element matches with these four respectively to the motor of front-wheel and trailing wheel, even if make wheel A and wheel B stressed unequal, also the work of two motor couplings can be obtained, the effect of two wheel balance motions.
When the former key element of identical ID, IS, IA and IB tetra-control is identical, as long as change the digital model function of setting, the different control signals that just can obtain multiple artificial setting export, solve and directly control two analog electronics by IA and IB two analog signals, only have a kind of mode, the shortcoming of mode can not be adjusted by human needs.
Whether stable state can be in leading rotational angle presumption bicycle, and by the size of leading rotational angle, the feedback control signal electric current I A produce cycle racing state and the difference delivery required by IB are revised, to ensure when bicycle plays pendulum, no longer labile factor is increased to bicycle, use morpet of the present invention more humane, safer.
