Abstract
The invention belongs to the field of automobile electronic control and particularly relates to an air bag control system. The air bag control system comprises multiple air bags, ultrasonic sensors, chair weight sensors, collision intensity sensors and a central processing unit, wherein the collision intensity sensors are used for detecting force generated when collision occurs so as to determine whether to open or close the air bags; the chair weight sensors are arranged below chairs and used for detecting whether the chairs are seated; each ultrasonic sensor is used for detecting the distance between the abdomen, the chest and the head of a passenger and the corresponding air bag; detected signals are transmitted to the central processing unit through the collision intensity sensors, the chair weight sensors and the ultrasonic sensors, and then the central processing unit determines the unfolding manner of each air bag.
Description
Technical field
The present invention relates to vehicle electronics field, particularly relate to a kind of control system of safety air bag.
Background technology
The development of automobile not only creates great function to social economy, and the life on the mankind also brings important impact.Vapour
Car have become as people trip main traffic instrument, its convenience be aircraft, steamer and train incomparable.
China is as newly emerging economy, it has also become the whole world the first big automobile consumption state, the vehicle guaranteeding organic quantity of current China is
Through breaking through hundred million.Car is many, and road is blocked up, and vehicle accident also gets more and more.
Accident research shows, air bag can be substantially reduced the chance of injury of human pilot, but due on current automobile
Air bag all ejects when vehicle collides, but time by bus, sitting posture is different, causes, when airbag-releasing, causing
Unnecessary injury.
How to make the effect reaching optimal of opening of air bag, reduce driver and the chance of injury of passenger in vehicle accident,
It it is current problem demanding prompt solution.
Summary of the invention
The present invention provides a kind of air bag start control device of vehicle, for solving above technical problem.Technical solution of the present invention is as follows:
A kind of air bag start control device of vehicle, including: multiple air bags, ultrasonic sensor, seat-weight sensor,
Impact strength sensor, central processing unit；The power produced when described impact strength sensor is for detecting collision, to determine peace
The open and close of full air bag, described seat-weight sensor is arranged on the lower section of seat and detects whether this seat has passenger, institute
State ultrasonic sensor for detecting passenger's abdominal part, thoracic cavity and the distance of head distance air bag；This impact strength sensor, seat
The signal detected is sent to central processing unit by chair weight sensor and ultrasonic sensor, and described central processing unit determines again
The expansion mode of air bag.
Described central processing unit is digital signal processing unit dsp processor.
Described crash sensor is arranged on front bumper, rear bumper, car door, left front beater or beat-up and right wing, left back
Beater or beat-up and right rear fender position.
The invention have the benefit that and by seat sensor, the position of driver and passenger is detected, according to detection letter
Number control the unlatching of corresponding air bag, determine that different air bag opens strategy according to different sitting postures, preferably protect
The safety and health of occupant.
Accompanying drawing explanation
Fig. 1 is the block diagram of the air bag start control device of vehicle of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described, it is clear that described is only a present invention part
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are institute under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
A kind of air bag start control device of vehicle, including: multiple air bags, ultrasonic sensor, seat-weight sensor,
Impact strength sensor, central processing unit；The power produced when described impact strength sensor is for detecting collision, to determine peace
The open and close of full air bag, described seat-weight sensor is arranged on the lower section of seat and detects whether this seat has passenger, institute
State ultrasonic sensor for detecting passenger's abdominal part, thoracic cavity and the distance of head distance air bag；This impact strength sensor, seat
The signal detected is sent to central processing unit by chair weight sensor and ultrasonic sensor, and described central processing unit determines again
The expansion mode of air bag.
When the power produced when the detection collision of impact strength sensor is more than the threshold values set, central processing unit controls to allow safety
Airbag-releasing；Seat-weight sensor is used for detecting on this seat whether have passenger, has under passenger status and can take advantage of this seat
The relevant airbag-releasing that visitor shields, otherwise closes air bag to save the follow-up cost of repairs；Ultrasonic sensor is used for
The expansion mode that detection passenger's abdominal part, thoracic cavity is different to determine air bag with the distance of head distance air bag, further ensures
The safety of passenger.
Described central processing unit is digital signal processing unit dsp processor.
Described crash sensor is arranged on front bumper, rear bumper, car door, left front beater or beat-up and right wing, left back
Beater or beat-up and right rear fender position.
By seat sensor, the position of driver and passenger is detected, control corresponding air bag according to detection signal
Open, determine that different air bags opens strategy according to different sitting postures, preferably protect the safety and health of occupant.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect the most in detail
Illustrate, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, all should wrap
Within being contained in protection scope of the present invention.
