Description
Technical field
The present invention relates to running car fields, more particularly to a kind of linked by automatically controlled Booster and ABS to realize ESC function
It can be with the method for active safety control.
Background technique
In car steering field, automatically controlled Booster can be real by motor driven master cylinder according to operator demand
Now to the braking of vehicle.Automatically controlled Booster can also realize active brake in the case where non-driver demand simultaneously.At present
Vehicle can all use automatically controlled Booster+ESC system in combination, Lai Shixian ESC function and active safety control.But ESC system cost
It is higher, and structure is complicated, is unfavorable for save the cost, and ESC system is unfavorable for repairing once damaging.Therefore, automobile is solved to drive
The problem of sailing ESC system higher cost in system, and structure is complicated, being unfavorable for save the cost is just particularly important.
Summary of the invention
ESC function is realized by automatically controlled Booster and ABS linkage to solve the above problems, it is an object of the invention to provide one kind
On the basis of current market Booster and ESC, it can provide and be substituted with ABS system with the method for active safety control
ESC system, the method for realizing ESC function and active safety, solves ESC system higher cost in automobile driving system, and
The problem of structure is complicated, is unfavorable for save the cost.
The present invention provides a kind of side that ESC function and active safety control are realized by automatically controlled Booster and ABS linkage
Method, the method are as follows: the cardinal principle of ESC and active safety function is exactly to carry out active pressure control to wheel, works as needs
When carrying out active pressure control to wheel, automatically controlled Booster active control pressure；ABS according to require open need active pressure
The corresponding normally open valve of wheel is controlled, makes this wheel and Booster connection, Booster directly controls its pressure；Closing does not need to lead
The corresponding normally open valve of dynamic pressure wheel, is isolated this wheel with Booster；The method may be implemented to carry out pressure to each wheel
Independent control realizes ESC and active safety control function.
Further improvement lies in that: when controlling required wheel: carrying out active boost to required wheel, pressure maintaining is let out
Voltage-controlled system, if active boost, by Booster active boost, being powered by ABS, closing is other not to need the normally opened of pressurization wheel
Valve, the wheel normally open valve no power of required pressurization, keeps clear, and is thus only pressurized to required wheel.
Further improvement lies in that: when needing to carry out pressure maintaining to required wheel, then present bit is kept by Booster master cylinder
It sets, keeps its output pressure, be still powered by ABS and close other normally open valves for not needing pressure maintaining wheel, the wheel of required control is normal
Valve opening no power, keeps clear, and thus required wheel carries out pressure maintaining.
Further improvement lies in that: when pressure release control need to be carried out, then master cylinder is withdrawn by Booster, reduces its output pressure,
It is still powered by ABS and closes other normally open valves for not needing pressure maintaining wheel, the wheel normally open valve no power of required control keeps logical
Freely, thus required wheel carries out pressure release.
Further improvement lies in that: the independent control that pressure of wheel braking cylinder is adjusted by Booter and ABS coordinated control, then it can be with
The functional and derivative active safety function of institute of realizing ESC is controlled by algorithm.
Beneficial effects of the present invention: on the basis of current market Booster and ESC, ESC system is substituted with ABS system
System, the method for realizing ESC function and active safety are realized the repertoire of ESC and are spread out by the linkage of ABS and Booster
Raw active safety function, it is ensured that the stable state of vehicle and the safety of pedestrian.

Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the examples below, the embodiment
For explaining only the invention, it is not intended to limit the scope of the present invention..
As shown in Figs. 1-5, the present embodiment provides one kind realizes ESC function and active by automatically controlled Booster and ABS linkage
The method of the method for security control, the ABS and Booster linkage is that ECU passes through external sensor signal realization ESC and active
The algorithm of security function judges, realizes that the active pressure of ESC and active safety function controls by automatically controlled Booster, and ABS is according to wanting
It asks opening to need the corresponding normally open valve of active pressure control wheel, is connected to this wheel with Booster, Booster is directly controlled
Its pressure；Closing does not need the corresponding normally open valve of active pressure wheel, this wheel is isolated with Booster；The method can be real
Pressure independent control now is carried out to each wheel, realizes ESC and active safety control function.
When controlling single wheel: ECU judge to pressurize to the wheel, pressure maintaining, and pressure release controls, when needing to wheel
Under pressure, by taking the near front wheel as an example, as shown in figure 3, Booster actively builds pressure, the near front wheel normally open valve is opened (no power), is made
The near front wheel is directly connected to Booster, is pressurizeed to the wheel；To the normal of the wheel (right before, left back, right after) for not needing pressurization
Valve opening, which is powered, closes, and makes itself and Booster isolation, is not influenced by Booster；Booster hands over master cylinder pressure signal and ABS
Mutually, it is ensured that the pressure that Booster is provided can be adjusted in real time up to the target value for actively building pressure.
When needing to carry out pressure maintaining to wheel, by taking the near front wheel as an example, as shown in figure 4, Booster maintains current master cylinder
Position keeps its output pressure, continues to open left front normally open valve, at this time the pressure maintaining of the near front wheel, before right, left back and right rear wheel
Continue to maintain a normally open valve energization closing, the isolation with master cylinder.
When needing to carry out pressure release to wheel, by taking the near front wheel as an example, as shown in figure 5, Booster withdraws master cylinder, it is reduced
Output pressure continues to open left front normally open valve to target value, and the pressure of the near front wheel can follow under the pressure of Booster at this time
Drop, to carry out pressure release, before right, left back and right rear wheel continue to maintain a normally open valve to be powered and close, the isolation with master cylinder.
