Fig. 1 is the schematic block circuit diagram of the utility model embodiment one;
Fig. 2 is the schematic block circuit diagram of the utility model embodiment two;
Fig. 3 is the schematic circuit diagram of the utility model embodiment one;
[specific embodiment]:
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment one: as shown in Figure 1, be that the electronic controller ECU control signal one tunnel of vehicle outputs to operator's saddle safety air bag firing circuit 2 at existing air bag system, operator's saddle safety air bag firing circuit 2 output signals connect operator's saddle safety air bag 3; The ECU control signal outputs to non-operator's saddle safety air bag firing circuit 7 simultaneously, and non-operator's saddle safety air bag firing circuit 7 output signals connect non-operator's saddle safety air bag 8; So, in case collision happens, ECU makes identification and judges, sends firing command, starts operator's saddle safety air bag 3 and non-operator's saddle safety air bag 8 simultaneously.The utility model is on the prior art basis, set up a non-operator's saddle air bag module automatic dialing unit, comprise a control circuit and occupy-place testing circuit, the first input end of control circuit is accepted the safety air bag control signal output ends of ECU, second input end is gathered the output signal of occupy-place testing circuit, the signal output part of control circuit connects non-operator's saddle safety air bag firing circuit 7, control circuit just can start non-operator's saddle safety air bag only in the firing command of receiving ECU with detect when being arranged at occupant's occupy-place information that the occupancy sensor on the non-operator's saddle sends.
The occupy-place testing circuit comprises occupancy sensor 4 and signal conditioning circuit 9, occupancy sensor 4 adopts weight sensor, when non-operator's saddle had the occupant, signal conditioning circuit was high level with the strain signal conditioning of weight sensor, exports to second input end of control circuit.
Control circuit is by AND circuit 6 and control gate 5.As shown in Figure 3, control gate is a delay trigger circuit, mainly is made of two-way d type flip flop U1 and peripheral circuit, and U1 selects the 74HC74 chip for use; Control gate is used for preventing moving or beating at the instantaneous human body that bumps, and causes sensor 5 signal to occur and changes or interrupt, and keeps the identification (keeping high level output) that not being shorter than in 500 milliseconds of times occupy-place.AND circuit 6 is by with a door U5 forming employing AND2 module, formation secondary AND circuit with a door U3, the 3rd with a door U4, first with second.
When automobile generation forward direction collides into, air bag system electronic controller (ECU) is made identification and is judged, sends firing command.One the tunnel directly delivers to operator's saddle safety air bag firing circuit 2, and chaufeur seat air bag 3 is launched.AND circuit 6 is delivered on another road, and can AND circuit 6 open and will look copilot's seat air bag and have or not the occupant to decide.
Control circuit is located at the sampled signal of the occupancy sensor 4 that the copilot attends a banquet by the collection of J7 terminals, when on the seat occupant being arranged, occupancy sensor is sent high level to control gate 5, thereby guaranteed that AND circuit 6 is opened, firing command continues to be delivered to non-operator's saddle safety air bag firing circuit 7, and copilot's seat air bag 8 is launched.When on the seat nobody the time, what occupancy sensor 4 was sent is low level, therefore locking of AND circuit 6, firing command can't hand on, copilot's seat air bag 8 is at a stalemate does not work.
Occupancy sensor can also adopt temperature (human temperature) or electromagnetic field sensor sensitive such as (existence of human body have disturbing influence to electromagnetic field), selects to use by the actual conditions of concrete vehicle.
Embodiment two: as shown in Figure 2, in this example, control circuit only adopts AND circuit 6, the control command of ECU is accepted in AND circuit 6 one tunnel inputs, one the tunnel gathers non-operator's saddle occupy-place information, and the occupy-place testing circuit adopts non-operator's saddle safety belt buckle trigger switch, when buckling safety strap when non-operator's saddle has the occupant, triggers a high level signal and offers AND circuit; This routine circuit is simplified greatly.Can realize goal of the invention of the present utility model equally.
