In an accident, a deploying airbag
asks for and gets Vehicle
Identification Numbers of
surrounding
vehicles.
Each vehicle's airbag(s) could come
equipped with a crash activated two-
way radio with two interrelated
functions.
1) in the event of airbag deployment
it
sends out
a "who is here? I've just
deployed, le'mme jot down your
digits, 'k?" signal. AKA
"WIH IJDLJDYDK" (presumably these
chipsets will be manufactured in
Bosnia.)
2) in the event of being near (say 25
meters?)a
deploying bag, the device answers
the
above question with "I'm vin
#4567H2345J23, bummer 'bout your
accident, dude" (or the equivalent
hexadecimal code)
Then when you submit your
insurance claim you also have the
documentation from the chip in the
airbag and they can call up the
insurers/owners of the other cars
and hash it out along with the
various accident reports.
Great for nabbing non-premeditated
hit and run drivers, drunks and
reluctant witnesses. Also good for
establishing who was where in
reconstructing the scene, especially if
there is some basic directional data
captured at the same time. Since it is
tied to the deployment of the Airbag,
it is restricted to just the more
serious events.
I think the outgoing message might
need to have a Vehicle identification
Number in it as well to prevent
random snooping pings of the "I
wonder who is here at the shopping
mall today, let's troll the parking lot
pinging" type. The vehicle being
pinged could get a signal that says
"check the log for the latest "WIH
IJDLJDYDK" signal history and
instructions for researching who sent
it.

I wouldn't advise actually putting it in the airbag, but OK. |
|
| |
As long as it included a firewall to stop people launching DoS attacks on your airbag. |
|
| |
"All your wreck are belong to us!" |
|
| |
ok, yes,[half] not inside the airbag
but
somewhere back in that bit of kit
that anchors and powers it... |
|
| |
I forgot to mention fembots in the
details. They can use this too. |

I thought cars came with firewalls
but did not know they were for
Driving on Sidewalk attacks.
Remind me to stay off the
sidewalks when you are around. |

So how does this distinguish between other accident-
mates, and nearby unrelated autos? You might run in to
illegal search laws, at least in the USA. If it depends on
other cars' airbags deploying, that won't work. My brother
hit another car head on at about 6 mph a piece. His
airbag popped, the other one didn't. And you'd have to
make sure to only hit other cars with the system. I like
the idea, but not the potential for implementation. We'd
have to start spending the extra cash now to get this in
our cars, for real benefit in about 20 years from now,
when the ratio of cars with to cars without is good enough
for regular use. |

1) how to distinguish between
accident-mates and non (great
term btw)? it doesn't. it just gets
the raw census data about the cars
in the vicinity. We let humans sort
out what it means. The placement
of "non involved" cars even parked
ones could influence the
settlement and adjudication as
they effect sight lines and might
contain witnesses. |
|
| |
2) Illegal search laws. Yeah I was
wondering about them. The
Supreme Court (US) seems to be
loosing interest in such niceties
but I think, even still, you are
legally obliged to bear witness if
you have seen an accident. And
lend aid if you can. This just
automates the witness
identification/scene detail
gathering process. |
|
| |
3) It does not depend on all the
airbags deploying. Just any one
bag going off sends out the "Who
all is here" message and then that
triggers the "me!" message (and
the "who asked" line in the log.) |
|
| |
4) yes it is understood that it
would take a while for the
prevalence to make it worthwhile.
But the same is true of common
bumper heights and was true for
basic controls in cars being the
same from car to car. As the
rolling stock is replaced (20 years
sounds right) this feature would be
more and more valuable. The first
car with this would be useless
(unless it got stuck in the
assembly line and got hit by the
second!) |

I plan on driving for the next 30
years or so and the kid won't be
behind the wheel for 16 or so...
can we sign you up? |
|
| |
Yeah, sure. My only hesitation now is the privacy thing. I
have no knowledge of any legal requirement to bear
witness either, although I do whenever I see any
accident, just
to be nice, and for karmic justice (which I don't believe in,
but what the heck). As they say, work it out in
production. |
|
| |
Ok Privacy... I don't think we have
it now... if you go an look at your
car's windshield on the driver's
side there is a place to look
through and down to see the VIN.
It is supposed to stay visible.
(see link). Plus the plates are
supposed to be unobscured as
well. |
