Body situation.
Then average force situation in each region is acquired, and compares the information of each region, it is possible to determine that cushion is each
Region stress condition, such as normal occupant's sitting posture situation are that the load in leg area should be less than stern section load, and left and right leg
Loading condition is identical, and left and right buttocks loading condition is identical, when there is slight load value if there is only left and right leg area, that
It can be determined that load is from article above cushion, moved back if there is an only left side or when right leg area limit load value, then
It can be determined that occupant is supported on seat with single knee, when if there is missing left or right side leg area load, and not
It lacks leg side and ipsilateral stern section load increases, then can determine that occupant is to stick up leg sitting posture at this time, and so on, but be not excluded for
The case where pole special circumstances can not determine, the aggregate-value of obtained load corresponding at this time may not be able to represent the true negative of occupant
Situation is carried, so there may be deviations for obtained air bag detonation grade corresponding at this time.
After judging load condition, determines which grade drive and passengers weight is according to the accumulated value of load suffered by each region, lead to
Often be divided into 0-5 kilograms without occupant state, 5-30 kilograms of occupant is child state, and 30-55 kilograms of occupant is petite women
Adult's state of state and 55 kilograms or more, the corresponding air bag of identification load condition open after quick-fried grade that (air bag opens
Quick-fried grade sets the classification of different weight occupant according to air bag producer or main engine plants), pass through data line output safety air bag
The discernible signal of control system or vehicle ECU.
