摘要： A supplemental inflatable restraint deployment system comprises an energy reserve capacitor, a first supplemental inflatable restraint deployment circuit comprising a controllable current source in series with a first squib, a second supplemental inflatable restraint circuit comprising a second controllable current source in series with a second deployment squib and a control unit for providing a first pulse of first duration to the first controllable current source to activate the first squib and for providing a second pulse of second predetermined duration to the second controllable current source to activate the second squib, wherein the first and second pulses are staggered with respect to each other.

摘要： A side impact sensor processes side acceleration signals and upon a crash event develops a deploy signal which comprises accurately timed pulses of preset duration including a single pulse wake up message and a multiple pulse deploy message. A single wire interface couples the deploy signal to a microprocessor in a central controller which manages deployment of side and frontal air bags and runs frontal impact algorithm. The pulse edges cause interrupts used to measure the pulse widths which are compared to stored values to verify the messages. A wake up pulse causes the microprocessor to give priority to an algorithm for processing the deploy message over the frontal algorithm and still service the frontal algorithm without degradation. Signal drivers in the side impact sensor impose sharp pulse edges for the deploy signal and sloping edges for other signals monitoring the state of health of the side sensor to reduce radiated emissions.

摘要： An inflatable restraint system includes a diagnostic circuit which measures the resistance of an external deployment path containing a squib. The circuit supplies a test current through the path and measures the voltage across the path which is monitored by a microprocessor. A vehicle battery supplies the power to the system and is connected to a constant current source in series with the external path to provide the test current. A current limiting device between the external circuit and ground comprises a current sink allowing a maximum safe current in the external circuit in the event of inadvertent application of battery voltage to the external circuit and, during a normal resistance test, imposes only a small voltage drop on the test current circuit.

摘要： Air bags are deployed by firing circuits each containing a squib in series with a common control switch, and a control containing an accelerometer and a microprocessor for operating the switch to deploy the air bags. To diagnose shorts, a current source feeds a trickle current through each squib and a current limited voltage regulator across the switch passes the combined trickle currents to ground. The microprocessor senses the voltage across the switch via an A/D converter. That voltage goes low for a short to ground and high for a short to battery voltage.

摘要： Large reserve capacitors store energy sufficient to operate the firing circuit and the deployment circuit for an SIR in the event of loss of battery or ignition voltage in a crash. A voltage doubling or tripling circuit charges the reserve capacitors. Normally the capacitors are isolated from the deployment circuit to minimize the load on the charging circuit. An isolation circuit detects the loss of ignition voltage and then connects a reserve capacitor to the deployment circuit for continued control operation.
