Description
Technical field
The invention belongs to car electrics field, and in particular to a kind of for recognizing that automobile rear has the perception of children's seat
System.
Background technology
The air bag of the front-seat positive co-driver of automobile is the part that automobile must be configured, when colliding, for right
The body and head of front-seat positive co-driver personnel are effectively protected.If being provided with children's seat on automobile, corresponding positions
The air bag put needs to be closed, and during avoiding colliding, air bag detonation causes wound to the children on children's seat
Evil.The copilot of front-row seats of vehicle is typically equipped with occupant's identifying device（Such as weight sensor, harness tension sensing
Device etc.）If being provided with children's seat on assistant driver seat, occupant's identifying device can recognize the children's seat and send signal
To safety air sac controller, safety air sac controller control co-driver air bag is closed（Suppress co-driver substitute
Capsule works）, when being collided so as to avoid, air bag for copilot detonation causes wound to the child passenger on children's seat
Evil.
With the rising of motor traffic accidents incidence, security configuration requirement of the people to riding vehicle also increased,
It is used to protect the heel row forward security air bag of heel row occupant also configured and use on automobile, exists the purpose is to mitigate heel row occupant
What body and head were subject to during collision scenario injures.Because current automobile rear is four or six points of seats and integral chair bone
Frame structure, it is different from front seat framework structure, it is impossible to which the occupant such as erection weight sensor, seat belt tension sensor recognizes
Device, it is impossible to recognize whether heel row has the presence of children's seat, if being mounted with children's seat on back seat, colliding
When, the detonation of heel row forward security air bag can cause serious impact to injure the child passenger on children's seat.
The content of the invention
It is right to meet it is an object of the invention to provide a kind of for recognizing that automobile rear has the sensory perceptual system of children's seat
Automobile rear judges demand with the presence or absence of the function of children's seat, prevents heel row forward security air bag from detonating on children's seat
Child passenger impacts injury.
It is of the present invention for recognizing that automobile rear has the sensory perceptual system of children's seat, including heel row ISOFIX interfaces
（ISOFIX is International Standards Organization FIX, refers to child safety seat fixed system）、
Vehicle power, electromagnetic relay, analog-digital converter and safety air sac controller, the heel row ISOFIX interfaces have first, the
Two conductive parts, one end of first conductive part is hanging free end, the other end of the first conductive part and the positive pole of vehicle power
Electrical connection, the negative pole of vehicle power electrically connects with coil one end of electromagnetic relay, the coil other end of electromagnetic relay and the
One end electrical connection of two conductive parts, the other end of the second conductive part is hanging free end, the hanging freedom of first conductive part
Holding can realize electrically connecting with the hanging free end of the second conductive part by the ISOFIX joints of the children's seat for inserting；The electromagnetism
Switch one end of relay connects vehicle power, and the input of another termination analog-digital converter of switch of electromagnetic relay, modulus turns
The output termination safety air sac controller of parallel operation.Safety air sac controller judges whether automobile rear is deposited according to the signal for receiving
In children's seat.The operating voltage of analog-digital converter and safety air sac controller comes from vehicle power and is changed through direct current transducer
The DC voltage for obtaining afterwards.
First, second conductive part is all formed by the conductive material being coated on heel row ISOFIX interfaces.
First, second conductive part is all the conducting strip being coated on heel row ISOFIX interfaces.
The conducting strip is copper sheet.
Its operation principle is：
When automobile rear does not exist children's seat（Children's seat is not installed on back seat）When, the first conductive part it is outstanding
The hanging free end of empty free end and the second conductive part is unrealized electrically connect, the first conductive part, the second conductive part, vehicle power and
The ISOFIX power circuits that the coil of electromagnetic relay is formed are not turned on（It is in off state）, the coil of electromagnetic relay
In there is no electric current to pass through, the switch of electromagnetic relay is off, and does not have signal input to analog-digital converter, analog-to-digital conversion
Device exports low level digital signal, and the low level digital signal is sent into safety air sac controller, safety air sac controller
Low level digital signal according to receiving is judged not installing children's seat on back seat, after safety air sac controller control
Row's forward security air bag normal work.
When automobile rear has children's seat（Children's seat is installed on back seat）When, the ISOFIX of children's seat
In joint insertion heel row ISOFIX interfaces, the hanging free end of the first conductive part is electrically connected with the hanging free end of the second conductive part
Connect, the ISOFIX power circuit quilts of the coil formation of the first conductive part, the second conductive part, vehicle power and electromagnetic relay
ISOFIX joints are connected, and have electric current to pass through in the coil of electromagnetic relay, and the switch connection of electromagnetic relay has voltage signal defeated
Enter to analog-digital converter, analog-digital converter is converted into high level digital signal, and the high level digital signal is sent to
Safety air sac controller, safety air sac controller is judged to be mounted with back seat according to the high level digital signal for receiving
Children's seat, safety air sac controller suppresses the work of heel row forward security air bag.
The present invention is using the control of heel row ISOFIX interfaces, vehicle power, electromagnetic relay, analog-digital converter and air bag
Device constitutes sensory perceptual system, and it can judge automobile rear with the presence or absence of children's seat, it is therefore prevented that heel row forward security air bag
Detonation injury is impacted to the child passenger on children's seat, both reached automobile rear do not exist children's seat when heel row just
To the demand of air bag normal work, heel row forward security air bag when automobile rear has children's seat is met again and is suppressed
The demand of detonation.Meanwhile, the ISOFIX formed by the coil of first, second conductive part, vehicle power and electromagnetic relay is led to
The connection of electrical circuit or the switch connection or off-state of off state and electromagnetic relay, sensing children's seat
Whether ISOFIX joints are inserted in heel row ISOFIX interfaces, its simple structure, easy to operate, low cost, and can standardized production.
