Scope.
As shown in Figure 1, a kind of novel full decoupling electro-hydraulic energy assisted braking system, operating mode are divided into normal mode of operation
With failure operating mode.Specific embodiment description is carried out from two kinds of operating modes now respectively.Wherein under normal mode of operation
It is divided into three kinds of damped conditions to be described, the pure braking mode of the first damped condition, i.e., completely by the driving of electric vehicle
Motor generates regenerative braking force, meets demand braking force；Second of damped condition is by braking mode and hydraulic braking pattern
Collective effect；The third damped condition is by pure hydraulic braking pattern.
Under normal mode of operation, the pure braking mode of the first damped condition, when driver's brake pedal 1,
Top level control unit ECU obtains the braking driving intention of driver, i.e. demand system by the stroke and speed of brake pedal 1
After power, it is found that after driving motor can fully meet demand brake force, the driving motor of electric vehicle is according to operator brake
Pedal signal generates corresponding demand brake force.The pedal sense of driver is simulated by first segment spring A14, first segment bullet at this time
Spring B8, second segment spring 9 are simulated.If pedal travel is shorter, i.e. driver's brake pedal 1 transfers force to pedal
Connector 2, compression first segment spring A 14 and first segment spring B 8, will be generated by first segment spring A 14 and first segment spring B 8
Reaction force simulates pedal sense；If pedal travel is more than the compressed line of first segment spring A 14 and first segment spring B 8
Journey will be generated reaction force by second segment spring 9, simulate pedal driving sensation.
Under normal mode of operation, second of damped condition braking mode and hydraulic braking pattern collective effect, when driving
During the person's of sailing brake pedal 1, top level control unit ECU obtains the system of driver by the stroke and speed of brake pedal 1
Dynamic driving intention that is, after demand brake force, it is found that after driving motor can not fully meet demand brake force, needs this system
Motor 13 carries out power-assisted, and motor 13 is after worm screw 12, worm gear 16 slow down, then by gear 17, rack 15 by rotation motion
Into translation, middle gear 17 and worm gear 16 are on same axis, and rack 15 compresses rack return spring 18, is pushed away with hour rack 15
Dynamic first piston 21, second piston 23 generate corresponding brake fluid pressure, and a brake fluid pressure part passes through the first pipeline 26, the
Two pipelines 27 flow through electronic stability program/anti-lock braking system 28, then pass through the near front wheel brake piping 29, off-front wheel system
Dynamic pipeline 30, left rear wheel brake piping 32, off hind wheel brake piping 31 are respectively acting near front wheel brake 33, off-front wheel braking
Device 34, off hind wheel brake 35 generate corresponding brake force on left rear wheel brake 36.The pedal sense simulation of driver at this time
It is simulated by first segment spring A14, first segment spring B 8, second segment spring 9.If pedal travel is shorter, i.e., driver steps on

Reaction force will be generated by second segment spring 9 with the compression travel of first segment spring B 8, simulates pedal driving sensation.
Under normal mode of operation, the third damped condition is pure hydraulic braking pattern, when driver's brake pedal 1
When, top level control unit ECU obtains the braking driving intention of driver, i.e. demand by the stroke and speed of brake pedal 1
After brake force, it is found that when motor cannot or not need to generate regenerative braking force at this time, system is completely by passing through motor 13 at this time
Power-assisted mode generates demand brake force, i.e., after driver's brake pedal 1, power-assisted effect, electricity just takes place in motor 13
Rotary motion is become to be translatable by machine 13 after worm screw 12, worm gear 16 slow down, then by gear 17, rack 15, middle gear 17
It is on same axis with worm gear 16, rack 15 compresses rack return spring 18, and first piston push rod 19 is pushed with hour rack 15
Compression first piston 21, master cylinder second piston 23 generate corresponding brake fluid pressure, and brake fluid pressure passes through the first pipeline 26, the
Two pipelines 27 flow through electronic stability program/anti-lock braking system 28, then are braked by the near front wheel brake piping 29, off-front wheel
Pipeline 30, left rear wheel brake piping 32, off hind wheel brake piping 31 are respectively acting near front wheel brake 33, off-front wheel brake
34th, off hind wheel brake 35, generate corresponding brake force on left rear wheel brake 36；The pedal sense simulation of driver at this time
By, first segment spring A14, first segment spring B 8, second segment spring 9 simulate.If pedal travel is shorter, i.e., driver steps on
Brake pedal 1 transfers force to pedal connector 2, compression first segment spring A 14 and first segment spring B 8, will be by first segment bullet
Spring A 14 and first segment spring B 8 generate reaction force, simulate pedal sense；If pedal travel is more than first segment spring A 14
Reaction force will be generated by second segment spring 9 with the compression travel of first segment spring B 8, simulates pedal driving sensation.
It fails under operating mode, i.e. motor 13 or other electronic apparatus parts fails, and driver steps on system at this time
Dynamic pedal 1, transfers force to pedal connector 2, then compresses mandril 3, pedal force then is transmitted to 14 Hes of first segment spring A
First segment spring B 8 is stepped on, then compresses second segment spring 9, when second segment spring 9 is more than between fail safe set 10 and bushing 5
Pretightning force when, fail safe set 10 can come off under the action of second segment spring 9 with bushing 5, the then pedal force of driver
It is transmitted to mandril and acts on first piston push rod 19, first piston push rod 19 overcomes the reaction force acts of rack return spring 18
On first piston 21, then compress first piston return spring 22 and second piston return spring 24 generate master cylinder hydraulic pressure power,
Master cylinder hydraulic pressure power flows through electronic stability program/anti-lock braking system 28, then pass through by the first pipeline 26, the second pipeline 27
The near front wheel brake piping 29, off-front wheel brake piping 30, left rear wheel brake piping 32, off hind wheel brake piping 31 act on respectively
Corresponding braking is generated near front wheel brake 33, off-front wheel brake 34, off hind wheel brake 35, left rear wheel brake 36
Power.
It is acted in conclusion the present invention can meet power-assisted when braking is stepped on to driver, passes through 14 Hes of first segment spring A
First segment spring B 8 carries out pedal sense first segment simulation, and pedal sense second segment simulation is carried out by second segment spring 9；It loses
It still can be braked under effect pattern using the foot pedal power of driver.
It is obvious to a person skilled in the art that the present invention is not limited to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requirement rather than above description limit, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
