Abstract
The present invention relates to a kind of brake-by-wire electronic vacuum booster with emergency stop switch, belongs to brake system of car field.Including controller and brake-by-wire electronic vacuum booster, the pin one and pin two of compound four emergency stop switch are normally open, pin three and pin four are normally off, power supply is in parallel with pin one and pin three respectively through fuse, pin two is in parallel with controller and brake-by-wire electronic vacuum booster, and pin four is connected with controller and brake-by-wire electronic vacuum booster.Advantage is structure novel, increase emergency stop switch structure, make booster that can also complete braking response in system exception, guarantees vehicle driving safety, and emergency stop switch can be arranged in any position of vehicle, only need all the way 12V power supply function starting can be realized, compare previous EVB, use is more convenient, braking dual fail-safe is provided for intelligent driving vehicle, convenient for arrangement, control is simple, is suitble to current intelligent network connection automobile application.
Description
Technical field
The invention belongs to brake system of car fields, especially the improvement to automobile brake-by-wire electronic vacuum booster.
Background technique
In previous brake-by-wire electronic vacuum booster, to realize active brake, usually inside booster assembly
Integrated electromagnetic motion component.When controller receives host computer signal, move electromagnetic component by control electric current or duty ratio,
The final active for realizing booster, meets braking system demand.When host computer, electronic vacuum booster controller or electromagnetism
When parts damages, it can also complete to brake in such a way that artificial foot is stepped on.
Previous brake-by-wire electronic vacuum booster, after controller receives the brake signal that host computer issues, to electricity
Magnet assembly issues electric current, and electromagnetic component movement is made to push atmosphere valve port open, and atmosphere enters booster and forms pressure, realizes booster
Active meets braking system demand.
Such brake-by-wire mode needs to step on using artificial foot when Vehicular system or the damage of EVB control system or crash
Mode is completed to brake.There must be related personnel to be sitting in steering position, just can guarantee intelligent driving ride safety of automobile.But with
Intelligent network connection automobile further develop, for save space, be usually not provided with position of driver, previous brake-by-wire electronics is true
Empty booster, not can guarantee vehicle driving safety functionally.
Summary of the invention
The present invention provides a kind of brake-by-wire electronic vacuum booster with emergency stop switch, to solve previous line traffic control
The problem of moving electronic vacuum booster, not can guarantee vehicle driving safety functionally.
The technical solution adopted by the present invention is that: including controller and brake-by-wire electronic vacuum booster, compound four
The pin one and pin two of emergency stop switch are normally open, and pin three and pin four are normally off, and power supply is distinguished through fuse
In parallel with pin one and pin three, pin two is in parallel with controller and brake-by-wire electronic vacuum booster, pin four and control
Device and the series connection of brake-by-wire electronic vacuum booster.
Power supply of the present invention is 12V.
It is an advantage of the invention that structure novel is guaranteeing original brake-by-wire electronic vacuum booster by structure optimization
Under the function of EVB, increase emergency stop switch structure, make booster that can also complete braking response in system exception, guarantees vehicle row
Safety is sailed, and emergency stop switch can be arranged in any position of vehicle, it is only necessary to function starting can be realized in 12V power supply all the way,
Compared to previous EVB, use is more convenient, increases manual intervention on the basis of original brake-by-wire, makes original braking system more
Add securely and reliably, provide braking dual fail-safe for intelligent driving vehicle, be convenient for arrangement, control is simple, and current intelligent network is suitble to join
Automobile application is the development trend of the following EVB.
Detailed description of the invention
Fig. 1 is the circuit diagram under normal condition of the present invention；
Fig. 2 is the circuit diagram under the compound four emergency stop switch starting states of the present invention；
Fig. 3 is the structural schematic diagram of compound four emergency stop switch of the present invention.
Specific embodiment
Including controller 1 and brake-by-wire electronic vacuum booster 2, one 301 He of pin of compound four emergency stop switch 3
Pin 2 302 is normally open, and pin 3 303 and pin 4 304 are normally off, power supply 4 through fuse 5 respectively with pin one
301 and pin 3 303 it is in parallel, pin 2 302 is in parallel with controller 1 and brake-by-wire electronic vacuum booster 2, pin 4 304
It connects with controller 1 and brake-by-wire electronic vacuum booster 2；
The power supply is 12V.
Working principle:
In the normal mode, compound four emergency stop switch do not trigger, and pin one, pin two are off-state, pin
Three, pin four is closed state, and the braking of brake-by-wire electronic vacuum booster 2 at this time is controlled by original controller 1, required
Braking maneuver is sent by controller and is instructed；
In emergency situations, after the scram button 305 for manually pressing compound four emergency stop switch, compound four emergency stops
Switch triggering, pin one, pin two are closed state, and pin three, pin four are off-state, brake-by-wire electronic vacuum power-assisted
Device 2 and controller 1 disconnect, and no longer receive controller instruction, directly by 12V power supply power supply, are directly connected by pin one, pin two
It is connected to brake-by-wire electronic vacuum booster, power for brake-by-wire electronic vacuum booster and drives brake-by-wire electronics true
Empty booster carries out the emergency braking of maximum power, reaches the state of emergency braking.
Claims (2)
1. a kind of brake-by-wire electronic vacuum booster with emergency stop switch, including controller and brake-by-wire electronic vacuum help
Power device, it is characterised in that: the pin one and pin two of compound four emergency stop switch are normally open, and pin three and pin four are
Normally off, power supply is in parallel with pin one and pin three respectively through fuse, and pin two and controller and brake-by-wire electronics are true
Empty booster is in parallel, and pin four is connected with controller and brake-by-wire electronic vacuum booster.
