The controller and the assist motor M1, the regulation motor M2 are communicated to connect, and the controller is according to being obtained
Master cylinder pressure, hydraulic booster cavity pressure, the hydraulic regulation cavity pressure taken, controls the assist motor M1 and the regulation motor
M2。
Specifically, pedal input shaft 7 is connect with pedal 1, and when driver's pedal 1, pedal input shaft 7 pushes input to live
S1 is filled in, meanwhile, the case where according to current vehicle, assist motor M1 pushes boosting piston S2, input piston under controller driving
The promotion of S1 and input piston S2 so that hydraulic booster chamber C1 generates pressure and main piston S3 is pushed to advance, meanwhile, controller driving
Pressure of the regulation motor M2 based on hydraulic regulation chamber C2 adjusts the position of the first regulating piston S4, close due to hydraulic regulation chamber C2
Closing property, it is fixed in hydraulic regulation chamber C2 liquid measures, the position of the second regulating piston S5 can be regulated and controled by fluid flow,
And then the decrement or elongation of spring 2 are controlled to adjust, to adjust the hydraulic pressure of hydraulic regulation chamber C2, and then adjust hydraulic booster
The pressure difference of chamber C1 and hydraulic regulation chamber C2, the input power of the pressure difference of stroke as master cylinder 13, master cylinder 13 are preferably tandem master
Cylinder (Tandem Master Cylinder, TMC).Therefore, pressure=hydraulic regulation chamber C2 that hydraulic booster chamber C1 pressure generates
The reaction force for pressure+master cylinder 13 that pressure generates.Therefore in certain pedal travel, regulation motor M2 adjustment springs can be passed through

So that adjustment spring 2 is extended, relatively low power-assisted is provided.When assist motor M1 and regulation motor M2 fails simultaneously, driver can pass through
Pedal input shaft 7 pushes directly on boosting piston S2 and input piston S1 advances jointly so that main piston S3 movements, while needing to protect
Hinder the minimum braking requirement of regulation.
In loose pedaling process, pedal 1 drives input piston S1 to be resetted under the action of return spring 6, meanwhile, power-assisted electricity
Machine M1 drives boosting piston S2 to follow input piston S1 returns.Preferably, assist motor M1 is non-self-lock-ing motor, then in failure mould
Loose pedal, assist motor M1 non-self-lock-ing can be pushed back under the high pressure of hydraulic booster chamber C1 under formula.
Following function may be implemented in the structure of the present embodiment：
1. input shaft stroke is identical, 8 journey variable of power-assisted input shaft of assist motor M1, to realize pedal limit row
The adjustment of journey；
2. when automatic Pilot, it can make assist motor M1 that boosting piston S2 individually be pushed to be braked, and defeated
It is motionless to enter piston S1, pinch can be led to avoid brake pedal autonomous action；
3. in assist motor M1 and regulation motor M2 failures, driver can push directly on input piston S1 and boosting piston
S2 advances together, ensures the minimum braking ability demand of legal failure mode；
4. can be adjusted by boosting piston S2 under Brake energy recovery operating mode so that the holding positions main piston S3, into
And it ensures master cylinder 13 and is not pressurized.
Further include the liquid pot 4 being connected to the hydraulic cylinder in one of the embodiments,.
The present embodiment supplements brake fluid by liquid pot 4 to hydraulic cylinder.
The liquid pot 4 is connected to by check valve 10 with the hydraulic cylinder in one of the embodiments,.

In the present embodiment, the adjusting input shaft 9 of regulation motor M2 has latching characteristics preferably on transmission mechanism, is falling
Under electricity or other failure conditions, it is ensured that pressure remained steady in hydraulic regulation chamber C2 avoids leading to accident because of hypotony
To hydraulic regulation chamber C2 fluid infusion bodies.Simultaneously electricity is adjusted if you do not need to using the first regulating piston S4 in course of normal operation
Machine M2 can be in standby mode, reduce power consumption and the requirement to motor.
First regulating piston hole, which is provided with, in one of the embodiments, limits the first regulating piston S4 activities
The limited block 3 of distance.
The present embodiment increases limited block 3, further avoids causing surprisingly to hydraulic regulation chamber C2 fluid infusion bodies because of hypotony.
Effect of the invention is that
(1) for liquid as pressure transmission intermediary, resiliency is preferable, and controllability is high.
(2) pedal travel adjust and assist rate (pedal force) adjust decoupling, it can be achieved that new brake feel by and real time stepless
Brake feel is adjusted.
