Deviation range, it is ensured that the air pressure of air bag 1 is controlled air pump 6 by essence and is adjusted within the scope of the tolerance of parameter C1, prevents because of essence
Control 6 degree of regulation of air pump is not good enough and 1 air pressure of air bag is caused over-voltage or under-voltage situation occur.
In actual operation, parameter C1 can become according to pre-stored data in the actual demand of user or control panel 3
Change adjustment.When parameter C1 changes, the fast charge shutdown pressure difference value B of fast inflator pump 5 can also change therewith, so that
The essence control section to work independently for essence control air pump 6 is formed between parameter C1 and parameter B, when essence control section has suitable range
When, both ensured that air bag 1 leveled off to preset pressure value under the effect of fast inflator pump 5 as far as possible, it is ensured that 1 air pressure of air bag is adjusted as early as possible
To preset pressure value, also it effectively prevent fast inflator pump 5 to occur the case where over-voltage because of Delayed shutdown, influences usage experience.Specifically
Ground, when the absolute value of parameter C1 is smaller, essence control section should be bigger, prevents air bag 1 from the case where inflating overpressure occur, works as parameter
When the absolute value of C1 is bigger, essence control section should be smaller, it is ensured that 1 air pressure of air bag is by fast 5 fast lifting of inflator pump to default pressure
Force value.
As C1≤20KPA, the KPA of 10KPA≤C1-B≤20, since preset pressure value is lower, as C1-B > C1, fastly
Inflator pump 5 can be in shutdown status in entire gas replenishment process, prevent air bag 1 from over-voltage occur under the effect of fast inflator pump 5
Situation, essence control air pump 6 complete the inflation work to air bag 1 by isolated operation.
As 20KPA < C1≤30KPA, preferred embodiment, C1-B=10KPA.Such as when C1=25KPA, fast inflator pump 5 is assisted
It helps 1 air pressure of air bag to be promoted to 15KPA, then 1 air pressure of air bag is promoted to by 25KPA by isolated operation mode by essence control air pump 6.This
Outside, the numerical value of C1-B, which can according to need, is adjusted, such as 7KPA, 9KPA, 11KPA, 15KPA etc., if meet 7KPA≤
