The Black Box
I am wondering if our cars have a "Black Box".
The reason I am asking is that last night I was watching the news and they was covering a car chase, and of course it ended in the death of two people, the driver and passenger.
So the police stated that they did not know how fast they was going but they would have to recover the black box from the car (2006 Honda civic, there was nothing left that was recognizable)
So do our cars have a black box? and where is it? can we access it?
Let me know what you know or think.

I wouldn't use the term black box but the ecu does record certain values. That is how BMW knows if you overrev, etc.

I think what he's asking is if there is a "box" that is recoverable after severe accidents. I guess it all depends on how well the ECU compartment is held together.

I know this is a common thing if the airbags explode. Long time ago I was watching Unsolved Mysteries and this pregnant woman got into a car accident and died. The cops ruled that she was driving recklessly and crashed. The family came forth and said she never drove fast and she is pregnant she wouldn't do that. They brough investigators in and they were able to see that she did hard brakes and accelerated very fast and when she crashed it was a high rate of speed so someone was chasing her.
I remember they said the car rerecords events and rewrites them until the airbags open then it saves the last set of data.

Here is a good article. I guess it's called an Event Data Recorder.

ECU records everything.
In trucks it can tell how many times you used engine brake or how many times the ABS got involved in braking.

yea there is something like that, as Sticky mentioned, the ECU. Two people I know had a race that ended up with an engaged couple being killed, so that came into play. But the info recovered may be limited considering the ROS before impact and also if & how the vehicle attempted to avoid the collision.

Well you can take our cars for example. When monitoring the car via OBDII, the car records if you spin the tires while braking, i.e. when you're at the track. If it records that, then I'm sure it records ALOT of other things.
