Chair is controlled, within the scope of the present invention.
After identification needs to be controlled seat, S32 is performed, otherwise, perform S33.
S32：The support pressure value of detection seat left and right sides airbag.
In specific implementation, when confirming not to be controlled the seat, can detect at the vehicle
When non-negotiation of bends state, the support pressure value of seat left and right sides airbag ensures to use so as to be informed in
During the normal driving vehicle of family, seat left and right sides airbag needs the support pressure value for providing.
S33：Detect the support pressure value of seat left and right sides airbag.
In specific implementation, when confirming to be controlled the seat, can detect that the vehicle is in
During negotiation of bends state, the support pressure value of seat left and right sides airbag, so, it is possible to
When obtaining vehicle in negotiation of bends state, because the effect of centripetal force etc. causes user to the seat
The influence of the pressure value that airbag is produced.
S34：Judge the direction of the vehicle traveling.
In an embodiment of the present invention, in order to the left and right sides airbag targetedly to the seat does phase
The adjustment and control answered, it can be determined that the direction of the vehicle traveling, the direction of the vehicle traveling can
Be vehicle bend travel direction.
In specific implementation, can be gone to judge that the vehicle is curved according to the steering wheel angle signal of the vehicle
The method of road traveling, when the steering wheel angle signal of the vehicle is more than zero, it may be determined that the vehicle
The direction of negotiation of bends is a left side, when the steering wheel angle signal of the vehicle is less than zero, it may be determined that institute
The direction for stating vehicle bend traveling is the right side.
S35：The direction travelled according to the vehicle and the difference of the support pressure value, accordingly by gas
Pump is respectively controlled to the support pressure value of seat left and right sides airbag.
In specific implementation, when being in negotiation of bends state in order to ensure the vehicle, the driver's
Security and comfortableness, the direction and the vehicle that can be travelled according to the vehicle bend are in bend row
The difference of state and the support pressure value of non-negotiation of bends state is sailed, accordingly by air pump to described
The support pressure value of seat left and right sides airbag is respectively controlled.

Can be tilted to the left, so as to be pressed in the left side of the seat, if the support pressure value in the left side of the seat
Do not make any adjustments, due to the inclination of driver's body, can cause the right crus of diaphragm of the driver from
The pedal for needing control is opened, so as to cause driving accident.By this control in one embodiment of the invention
Measure, you can avoid this problem, such that it is able to lift the security and comfortableness that are driven during negotiation of bends.
In an alternative embodiment of the invention, when the direction of vehicle bend traveling is right, control is described
Air pump stopping is seat left side air bag inflator, seat right side air bag inflator is continued as, until institute
The support pressure value for stating seat right side airbag is equal to the seat when vehicle is in non-negotiation of bends state
The support pressure value of right side airbag.So, you can avoid the influence due to centripetal force, be likely to result in
The traffic accident that is caused to the out of control of vehicle of driver.
In specific implementation, in order to improve the hommization degree of negotiation of bends control, may also receive from
The regulation actuating signal of user, and described seat or so two is correspondingly adjusted according to the regulation actuating signal
The support pressure value of lateral airbag, so that obtain user can be according to demands of individuals, by seat regulation to the most comfortable
State.
In an embodiment of the present invention, in order to improve the intellectuality that negotiation of bends is controlled, institute can also be recorded
Adjustment result of the user to the support pressure value of seat left and right sides airbag is stated, when vehicle is again started up
And when being not detected by user the seat being adjusted, by the branch bulging of seat left and right sides airbag
Force value is initialized to the adjustment end value.So, same user need not just adjust every time, i.e.,
The suitable seat state of oneself can be enjoyed, so as to improve the comfortableness of driving.
