The operation principle of the present invention is as follows：
(1) when vehicle is manned mode, as shown in Figure 2：
When vehicle is arranged to manned mode, or driver forces to step on pedal to enter and had under unmanned pattern
During people's driving model：Controller 7, which controls, causes first switch valve 4 open in usual to be in opening, at normally closed type second switch valve 5
In closed mode.
(1) when braking：During driver's brake pedal 3, brake pedal 3 chooses to install around pin joint promotes brake pedal to push away
Bar 26 is moved to the left, and brake pedal force is delivered to power assisting device 21 by brake pedal push rod 26, and power assisting device 21 produces power-assisted
Acting on and brake force is passed into second piston bar 22, first switch valve 4 open in usual is opened, and normally closed type second switch valve 5 is closed,
Second piston bar 22 moves to left the hydraulic pressure rise for causing second chamber 12, and brake fluid (is now switched by first switch valve 4 open in usual
Valve is opening) enter first chamber 11, the hydraulic pressure of first chamber 11 also increases.When continuing brake pedal 3,
The hydraulic pressure of second chamber 12 and first chamber 11 continues to raise, and elevated hydraulic pressure passes through brake monitor 14 and brake piping
2 conduction, finally raise the hydraulic pressure in left front brake 15, right front brake 16, right rear brake 17 and right front brake 18,
It is final to produce brake force.
(2) when releasing braking：Driver loosen the brake 3 when, first switch valve 4 open in usual is opened, normally closed type second
Switch valve 5 is closed, and brake pedal 3 and the wheelcylinder piston of second piston bar 22 and each brake act in respective return spring
Lower return, the oil return valve that the brake fluid in brake piping 2 is pushed open on master cylinder 1 flow back to master cylinder 1, brake fluid eventually through
First switch valve 4 open in usual flows into second chamber 12, realizes brakes pressure release, and brake force releases.
(2) when vehicle is unmanned pattern, as shown in Figure 3：
When vehicle is arranged to unmanned pattern：(1) now brake pedal 3 does not produce without active force, power assisting device 21
Power-assisted is acted on, and second piston bar 22 is not moved；(2) controller 7 control cause first switch valve 4 open in usual be closed,
Normally closed type second switch valve 5 is in opening.
(1) when braking：After controller 7 sends braking instruction, electric machine controller 24 receives the brake signal of controller 7
When, motor 23 starts, while electromagnetic clutch 25 combines, and the rotary motion of motor 23 is converted to directly by worm gear 10 and worm screw 9
Line moves, and worm screw 9 promotes First piston bar, and toward moving to left, master cylinder second piston bar 22, which moves to left, causes the 3rd chamber 13
Hydraulic pressure raises, and brake fluid enters first chamber 11 by normally closed type second switch valve 5 (now switch valve is opening), and first
The hydraulic pressure of chamber 11 also increases.When motor 23 is rotated further, the hydraulic pressure of the 3rd chamber 13 and first chamber 11 continues to rise
Height, and elevated hydraulic pressure is conducted by brake monitor 14 and brake piping 2, finally makes left front brake 15, right preceding braking
Hydraulic pressure rise in device 16, right rear brake 17 and right front brake 18, finally produces brake force.
(2) when releasing braking：After controller 7 sends releasing braking instruction, motor 23 is inverted, and the rotary motion of motor 23 is led to
Cross worm gear 10 and worm screw 9 is converted to linear motion, worm screw 9 drives First piston bar 8, and the wheelcylinder piston of each brake exists toward moving to right
The lower return of respective return spring effect, the oil return valve that the brake fluid in brake piping 2 is pushed open on master cylinder 1 flow back to braking master
Cylinder 1, brake fluid flow into the 3rd chamber 13 eventually through normally closed type second switch valve 5, realize brakes pressure release, brake force solution
Remove.Last motor 23 stops operating, while electromagnetic clutch 25 separates.
The present invention also provides a kind of vehicle, including Vehicular brake device, and the Vehicular brake device is the various embodiments described above
Described Vehicular brake device.
