The Most Complex System In Modern Cars

An airbags, in its most elemental forms is an automotive safety restraint system designed to inflate a cushioning bag extremely quickly, then rapidly deflate it in a controlled manner, during a collision. They’re considered a passive restraint system, because unlike seatbelts, they require no interaction by the occupant for their operation.
SYSTEM DESIGN
An airbag system is fundamentally composed of one or more inflation mechanisms located primarily within the steering wheel for the driver and the upper dashboard for the front passenger. These inflation mechanisms are controlled by a centralized system that continuously monitors for impact events using as little one to dozens of sensors, depending on the system’s sophistication. Once this system detects an impact, one or several inflation mechanisms are pyrotechnically triggered by an electrical signal, causing a gas generating propellant to be ignited, rapidly inflating a bag that is folded within each inflation mechanism. While simple in concept, the difference between an airbag’s deployment protecting an occupant, and causing traumatic or even deadly injuries, comes down to the precise millisecond timing of its operation.
ANATOMY OF AN COLLISION
This incredibly narrow window to act within the first ⅓ of the entire collision duration is due to the airbags needing to deploy before the occupants contact any portion of the vehicle interior as it crushes, and before the limits of the seat belt’s stretch are reached. The airbag’s inflation must also be timed so that it is fully inflated before the occupant engages with it, to minimize trauma from the inflation process itself.
COMPRESSED AIR
Both systems were based on a store of compressed airbags that would inflate the airbag using mechanical trigger valves. By the 1960s, practical airbag systems for vehicles were being explored by the major manufacturers and from this decade of research it was determined that compressed air systems were far too slow reacting to be effective. These flaws made the mechanical compressed air airbag system completely unsuitable for commercial adoption.
A BREAKTHROUGH
Allen K Breed would make a breakthrough that finally made airbags commercially viable, with the development of the ball-in-tube electromechanical crash detection sensor. When a collision occurs, the ball is separated from the magnet, moving forward to electrical contacts and closing the trigger circuit. Breed also pioneered the use of a gas-generator as a method for rapidly inflating an airbag. Breed devised an inflation mechanism that used just 30-150 grams of the solid-fuel, sodium azide as a gas generating agent for airbags. The sodium azide would then exothermically decompose rapidly to sodium and nitrogen, fully inflating the airbag with the resultant gas, within just 60-80 milliseconds.
AIRBAG HISTORY
Any car sold in the United States must now be certified to meet the Federal Motor Vehicle Safety Standards or FMVSS, a comprehensive set of regulations on vehicle design, construction, and performance. The NHTSA began to prepare for a second wave of mandates during the 1970’s, specifically targeting a push for new safety technologies, with the airbag being a prime technology for regulatory compliance. The first mass-produced vehicle to have an airbag system was introduced on a government-purchased in 1973. Called the The Air Cushion Restraint System or ACRS, General Motors employed impact sensors mounted in the vehicle's front bumper in order to deploy the airbags embedded in the steering wheel, for the driver, and in the dashboard for the passenger.
By 1984, the NHTSA would reach a compromise with the industry, and with this agreeing to the introduction of a passive restraint system mandate for all new vehicles produced in the US, beginning on April 1, 1989. Manufacturers had 2 options, either an automatic seat belt system or the airbag.
The 1980s saw the shift of the industry's view of airbag as a primary safety system to one designated as a supplemental restraint system or SRS, or the less common designation of supplemental inflatable restraints or SIR.
THE NEXT WAVE OF AIRBAG TECHNOLOGY
This proliferation led to the development of a new generation of airbag systems during the 1990s that overcame the flaws of earlier systems through the use of recent breakthroughs in the semiconductor industry.
ALGORITHMIC CRASH DETECTION
The electronic control unit that formed the backbone of airbag systems, called the airbag control unit or ACU, would now become an embedded computer, relying on a fusion of MEMS sensor data and other vehicle inputs, to employ algorithms that could now manage a larger spectrum of collision types and inflation response profiles.

    Very well explained . I spent ten years working in the airbag gas generator industry, focusing on quality and functional testing. For driver and passenger frontal airbags, the generators contain two pyrotechnic charges of different sizes that can be triggered with a delay determined by the calculator, depending on the speed of the impact and deceleration to modulate the deployment speed of the airbag so that it is fully deployed by the time the person makes contact. A few milliseconds of advance or delay are sufficient to avoid suboptimal functioning that could lead to inadequate protection or worsened injuries. For side airbags and curtains, the generators are hybrid. They function with both a pyrotechnic charge and a neutral gas under pressure, or nitrous oxide, to provide a colder gas.

Counterintuitively, cars rolling - assuming the roof is sufficiently strong so as to not collapse on the passengers - is actually often helpful in preventing serious injury, as the car's velocity is bled off over a large distance, instead of a much more sudden stop. It's facetious to say, but it's not the fall that kills you, but the sudden stop at the end. Had you _not_ rolled, my guess is you'd not be alive today.

The most enjoyable driving experience I have ever had was at the helm of a 1949 Hudson Commodore, second best a 1954 Plymouth Savoy, third best my 85 F150. None of these vehicles would do shit for me in a wreck(The F150 would, at least, retain my corpse within the cabin as it has 3-point seatbelts but let's not kid ourselves here that thing won't do anything to protect me in a wreck either), but they are orders of magnitude more pleasant to drive. Meanwhile, my 14 Challenger would do reasonably well in a crash BUT I FUCKING HATE THAT GOD DAMNED PIECE OF SHIT! I can't see out of it, I can't get comfortable in it, I feel like I'm in a goddamn sardine can because the dash, console, door cards all squeeze me so tight. The seat is horrid to sit in. I can lose a peterbilt behind the A-Pillars and the C-pillars render shoulder checks near pointless. My head hits the roof, I had to remove the headrests to be able to shoulder check without cold cocking myself...I could rant on for days about that car, but to keep it succinct, the only part about it I can not find fault in is the radio. If someone hadn't gotten it before I got the money raised I would have happily replaced the Challenger with that 54 Plymouth I drove. Not a moment's hesitation. And there is a 52 Chevy for sale in my area still......

But, to be fair, I was in an SN95 GT that I bought at auction (see the video series on my channel called "Auction Car Rehab" if you're into that sort of thing...which you sound like you are) when a dude in a Caddy trying to beat a yellow light, ending up basically hitting me head on. His car turned into a cannoli, my seatbelt barely even tried...the airbags had apparently been out to lunch. He didn't have a scratch on him, I ended up needing 8 staples in the top of my head and had a CRAZY concussion (or something?...weird shit happens when you hit your head...lol) for about a week where I had weird bruising at the back of my jaw bones, felt like I had a cold, couldn't remember shit...all kinds of weird shit. lol Cars ABSOLUTELY HAVE become the mechanical embodiment of helicopter parenting, but it's not all for naught. I work in IT security and it's similar...it's always a trade-off between privacy (visibility, comfort, cheap, simple) and functionality (728 airbags, pre-tensioning seatbelts, cars like the new Audis that can LITERALLY lean into an oncoming collision, etc). We can't really have it all. Unfortunately.

    @@rmp5s I'm pretty familiar with the SN95 Mustang even though I nver owned one. My best bud in HS had a V6 5-speed SN95 and he beat the SHIT out of it. Totalled it twice, wrecked it 4-5 times, still managed to get it back on the road himself every single time. Go figure. For me the tradeoff just is not worth it. I'd rather drive the old iron instead. I love the sound of their engines, the 3-on-the-tree shifting, the 'this bench seat is more comfortable than the couch in your living room' seating, the roomy interiors, great visibility, plush ride....yeah itt'l kill me in a fender bender but I'm fine with that. And if I really wanted to be totally pointless they actually do make airbag retrofits for those old cars! Some are totally self contained modules bolted to the center of the steering wheel and are pure analog devices, others do have a rudimentary electronic trigger system like you saw in the early generations of factory airbags. Why you would fit them to these old cars is beyond me because there's no crumple zones, the steering columns just turn into spears in an impact, the doors pop open, the seats come out of the floor and fly around...I 'spose you're not supposed to install them standalone, but combine them with a modern collapsible steering column, partial roll cage, bucket seats padded dash, seatbelts, etc. May not bring a 54 Plymouth up to 2023 crash standards but it's certainly plausible for an enterprising gearhead to bring one at least up to the mid 90s. Got my eyes on a 1953 Ford Mainline Business Coupe and a 1941 Packard 8. Both are stunning cars, both contain things you don't see every day(Business Coupes don't exist, nor do straight 8s), both are in good shape, both are at or below 20 grand. The Ford has the advantage of better part support(The 8BA Flathead in it is still enjoying a thriving hotrod scene so I can buy pretty much any part for that engine except the block itself!), but the Packard enjoys 163hp, 0-60 of 13s and change, top speed of 107 which puts its straight line performance on par with a brand new $20,000 car. AKA itt'l be more comfortable on the interstate. Decisions decisions. Oh, and I'm also getting my F150 back on the road. Worn out engine is pulled, waiting on clutch kit, when that arrives I'll be stabbing a used-but-good engine down into it.

    Deploy on open isn't the best idea for a few reasons, one of the biggest is sensors degrading. Cars live an awful life for a machine being exposed to frigid temps, high temps, and lots of salt. Airbag sensors can often times form corrosion on conductors over time which can break the circuit open eventually. Having an airbag deploy while driving is pretty likely to lead to an accident on its own, with the unfortunate side effect of no-longer having an airbag. I know this is an old comment, but I'm scrolling so maybe someone else will too.

    No, I don't think you can say that, although they perhaps are built in a way that resembles microscopic spring mechanisms. Modern accelerometers can measure positive or negative acceleration as a three-dimensional vector to multiple digits of precision, whereas the earlier mechanical sensors were more like "on" and "off" - that's the point of the whole segment where he talks about detection profiles, advanced algorithms and computing power; all stuff that is decidedly _not_ possible unless you have very accurate data on the (crashing) car's movement and acceleration/deceleration in 3d space.
