Senna crash car telemetry
jwb...@hotmail.com
Faculty of Technology here in Kingston University in the UK.
We observed certain occurences that I believe you might find of
interest. The information here is shared information with CINECA
Italy, (Image Processing division responsible for footage on Senna crash
car).
A brief analysis was carried out of the publicly available footage on
CINECA's website, you can view the mpeg, mov footage yourself and follow
this analysis. The website is http://www.cineca.it/visit/SENNA/
I will try to summarise what was written.
Upon viewing the enhanced footage it was noticed here at the School of
Information Systems, (Faculty of Technology) that;
1. cam_car.mov
As the car passes the Q8 advertisement on the right side (approxiamtely
3.00 seconds into the footage (cam_car.mov), as soon as the nose passes
the advertisement you'll notice that the car strikes a bump in the road,
at quite a force. When one examines the yellow button on the steering
wheel one finds that just before this point, it lowers significantly,
as if the steering column is slipping in the housing. MORE
IMPORTANTLY---> As soon as the car hits this bump
you notice that Mr A. Senna, looks down onto his dashboard, as if he
also senses that something is wrong. As if something is slowly coming
apart.
This reaction is very visible in zoom_tr.mpeg, watch the footage, and
wait for the reaction... (3 seconds into play)
As Mr A.Senna enters Tamburello, we have noticed the following. When the
clock in cam_car.mov hits 11.24 seconds into play,.. the front wheels
point away from the direction of travel, towards the right. It seems as
if at this point the "steering column" breaks. But NO! We have
found this:
At 11.24s seconds Mr A.Senna applies slight opposite lock to the
steering wheel,... probably to ease off the 3.62g LATTACC that has been
building up (sensing something might break or perhaps simply because of
driving style) BUT as soon as the "little yellow button" on the steering
wheel pops up into view at the bottom of the screen (I.E. As soon as Mr
A.Senna applies even the slightest Rightside opposite lock from having
previously been turning left, the front wheels detach from his input.=
The steering column breaks (somewhere
between 11.24s - 11.28s)
So (we believe) it is a stress fracture induced by long term torsion
effects that causes steering column failure on FW-16. And the proof is
there,. From a continuing pressure on the steering wheel from turning
left, a stress fracture induced by long term torsion effects, occurs at
between 11.24-11.28 seconds, when Mr A.Senna applies opposite lock
towards the right (seeing as LATACC has been building up to 3.62g
possibly sensing something is about to break/snap). As soon as this
opposite lock STARTS (11.24 seconds) ---snap.the column breaks, and the
wheels point away, never to return. No matter what the steering input
(11.40s until ~11.80s)
NOTE://
The LATACC reading is slow in "catching" up with the fact that lateral
acceleration at 11.24 seconds is reduced to the region of zero, as it
registers a decrease only at 11.30 seconds.
This fact we believe is the most important piece of information we at
the School of Information Systems have been able to extract from the
footage.
NOTE2://
Moments before impact with the wall in the third perspective camera
angle the front left wheel shows highly distorted toe-in toe-out, again
in accordance with a MECHANICAL failure (Steering,.. not suspension, not
pressure (Tire or Human))
That summarising and concluding:
1. Upon hitting the bump (~3) seconds into cam_car.mov
Mr A .Senna senses something is wrong and looks "down"
onto his steering wheel.
2. The car is building LATACC to 3.62g at 11.24s, invokes an opposite
lock reaction from Mr A.Senna (perhaps because he senses something is
just about to snap or perhaps simply because of driving style), causing
the steering column to break at THIS point in time (11.24 s),... The
steering column snaps, and the front wheels never change their angle
after 11.24s, no matter what the input from Mr A.Senna afterwards
(11.40s to ~11.80s).

During the trial it WAS proved that his accident was caused by the steering
column failing.
Why the trial went on for so long was that they were trying to determine
whether anyone (i.e.: Williams,Head,Newey) was to blame for this.
I ask all of you out there, if one of your loved ones (wife,Husband,Kids
etc...) got killed because of a faulty object at work (lets say electrocuted
by a faulty computer?? for arguments sake). Wouldn't YOU want to know IF
someone was to blame and if so wouldn't you want them prosecuted??
Hmmm makes you think a bit when it involves yourself doesn't it????
Aubrey
definitely moving way off its normal axis. Glad no one got convicted
though. These things just happen in racing.
Although, the bit about Senna looking down at the steering wheel is just
silly. Surely, no one can judge what he's looking at from the back of his
helmet. There's all sorts of things on the dash he could have been looking
at.
BTW I don't see what Kingston University has to do with any of this. The
CINECA site makes it look like they figured it out on their own.
Very interesting at any rate. Thank you.

I was never convinced and remain so. I have the '94 review video which plays
Senna's last lap up to the point it all goes wrong. IMHO the most telling
piece of evidence is the car oversteers slightly (jinks to the left) prior
to veering right. On top of the very visual evidence of Senna's car
bottoming out repeatedly (this was also observed by MS) I still think the
most likely explanation is too low a ride height, compounded by a possible
slow puncture. The safety car period would have lowered the temperature (and
hence pressure) of the tires significantly. Senna's head does move to the
left, but my reading of that is that he is all to aware of that wall on his
right hand side which I suspect he knew he was going to hit.
I see no evidence at all for steering column failure. Put it another way,
you're turning left on a very fast corner, which no doubt requires quite a
bit of effort from the driver. If the column suddenly failed I would expect
to see a very sudden movement of the wheel and Senna's hands to the left,
which just isn't there (ever used a spanner/monkey wrench which suddenly
slips on the bolt and your hand carry on in the direction of pull?).
That's my reading of it anyway.
I guess we'll never know for sure, likewise with many other accidents. In
the end it was just that, a racing accident. Not the first and not the last.

I also remember MS saying that the car' rear end was hitting the road hard.
Maybe Senna knew then that he would'nt make it trough the curve with the
rear end following the front (he felt the oversteer) and that's why he ease
off the steering input to the left.
On the other hand, (I don't know about you) but I don't know how a carbon
steering column break. Does it break all at once (wich would produce the
sudden movement you are talking about) or does it slowly delaminate and
altough the steering wheel stays at the same angle, the wheels get back
straight. To know for sure we woulg have to know the input force to the
steering wheel from the driver's arms... Something wrong for sure is that we
clearly see the steering wheel go off his axis and that's not supposed to
happen.
The fact that the subject is debated 5 years after the accident indicate
that there's a lot of different opinions about the facts.

The facts are this:
Senna's car never went by the pitlane after the accident to transmit the
onboard telemetry. While the Renault engine blackbox was salvagable, the box
containing every other performance telemetry was damaged beyond extractable
use. Nobody ever saw what was stored in it. And it was _not_ submitted in
the court case against Williams and the Imola organizer for that very
reason. So exactly where CINECA got their hands on this so-called telemetry
is because they _invented_ it to get the recognition.

Apparently, it wasn't on their website until December '97, which is why I
hadn't seen it until yesterday. It's under the "New Image Processing" link.
There's another mpeg which is far too small to make out anything in the
cockpit, which was the only one I knew of before. In zoom_tr you can really
see the steering wheel gradually coming loose in his hands, and wiggling up
and down abnormally. Personally, my mind is pretty much made up.

You must be right, I'm sorry about my statement about the carbon column. I
have pictures I took in the tub of the 96 Minardi and it definitevely shows
a metal column (with the electrical connections for the steering electrical
hardware in the center of the column). But I have to put my hand on the info
wich led me to beleive that it was a carbon column all that time...

telemtry to prove it was a car handling issue, not a break in the
column that caused the crash,... so if there was no telemtry williams
made some up aswell.

alone,.. what does your university have to do with this?
2.) Good idea but how do you know he didn't just hit a bump and
understeer off the track?
I would appreciate a reply...

> alone,.. what does your university have to do with this?
1. I can see why my original posting could have been misleading, my
apologies. The information as posted, has been merely (as it says)
"shared" with them. We (myself and several Imagery/Information systems
people) started a personal research project and shared the results with
CINECA of Italy. That is all, there is absolutely no collaboration
between CINECA of Italy and Kingston University! All credit to the
imaging work lies solely with CINECA of Italy.
> 2.) Good idea but how do you know he didn't just hit a bump and
> understeer off the track?
2. Good Question...
I understand your argument:
Senna bottoms out --> opposite locks --> understeers off the track
yet this is the problem with that argument;
A.) From the enhanced video footage we can see the front wheels'
direction stay absolutely constant after 11.24 seconds. I.e. after your
proposed "understeer" starts, or after my proposed steering column
breaks, the tyres on the williams DO NOT "visually" change direction,
even though we can see A. Senna's hands jink the steering wheel, left,
left, left, and then his head, left, left, left.
((A.1) Advanced reasoning = You may say that the tyres do not change
direction to the left because Mr A. Senna tries to keep the car stable,
and provide maximum braking grip in a straight line, and HE keeps the
tyres facing forward, and therefore we do not see them trying to go
left, so there is no steering column failure. But this is wrong--> HUMAN
psychology tells you that if his hands are pointing the steering wheel
in a straight line. His head would not be jinking left, left, left.)
B.) The "understeer" argument does not account for the abnormal toe-in,
toe-out visible on A. Senna's left front tyre milliseconds before impact
with the wall. A steering column failure will.
C.) If it were true that A. Senna understeered off the track at 190 mph,
most drivers will tell you that, one brakes at maximum braking force,
then as you are about to impact the wall you release braking force to a
certain extent, and try to steer away from the obstacle. A. Senna would
have RELEASED braking force at the last minute before trying to steer
away from the wall, --> UNLESS he knew there was no more steering. DO
you see? If the front tyres did not grip, he would brake at maximum (as
he did), and at the last minute release the brake and try to steer away
(to reduce impact angle), certainly his speed way low enough at impact
to release the brake and attempt to steer (+-120 mph I believe) Although
the track surface was debatable. Any driver would do this by instinct,
NOT brake all the way into a wall. A.Senna would surely have tried a
last minute steering input at reduced braking force, UNLESS he knew
there was no more steering, only a brake pedal, in which case he would
do what he did --> reduce speed as much as possible before impact.
(check telem.)
D.) I believe that A. Senna's head movement, the left, left, left.. is
not in accordance with normal car mechanical functioning. I realise it
sounds opinionated, and it is perhaps my weakest point. It seems as if
the left, left, left head movement is a reaction that stems very much
out of surprise rather than understeer.
E.) Again you can tell from the tape,.. the front wheels do not change
direction, look and see, understeer is when there is no grip no matter
WHAT the direction they point in, in this case they point in one
direction ONLY.
To me this is definitely a steering failure.

cause the crash would be Senna. And even then, he may not have known what
happened. There is no way now anyone can say - this is what happened or
that is what happened. It is impossible to prove, we can only speculate.
This is true for most major crashes, especially ones which unfortunately
result in fatalities.

available information there is, and subsequently reach a conclusion that
provides the most likely explanation of what happened.
I am sure that the driver in the final moments of that racecar had no
where near enough time to evaluate all the telemetry figures, in the way
that is done now. Perhaps it was too quick even for the driver to
realise what was going on. (And provided the telemetry studied is
genuine) researchers now have days and days to look at the ride
heights, suspension values, tyre pressures, and have the ability to come
to perhaps a better conclusive reason as to what happened, than even the
driver.
One of the most efficient ways of doing this, as I am sure you are aware
are usergroups/newsgroups.

You're Paul Ryder from AtlasF1 news. One of the best F1 news archives on the
www by the way.
I don't know if you wrote this AtlasF1 news item, the author is Atlas Team.
But here you go. From AtlasF1 news, March 18, 1997:
"I authorized the Williams representatives to remove the black box
immediately after the accident - but the efforts made at the circuit to read
the data were all in vain." Charlie Whiting, FIA Technical Director,
testifying at the Senna Trial (AtlasF1, March 18, 1997).
In AtlasF1 news two weeks later:
"Ayrton Senna's Williams 'black box' was scrutinised today when the Trial
Senna continued. Witnesses had said that this recorder was damaged and could
not be linked to the team's computer. Marco Spiga showed the court how the
recorder worked: with a three pin connector. The session also showed however
that the recorder also needed a data card in order to send information....
The prosecution said: "Only today are we told we need a card. Williams never
told us this before. Why wasn't it made available?"...Reply: "Because we
were only asked for the pin connectors." " (AtlasF1, April 2, 1997)
Let's go back to March 17, 1997, and we find on AtlasF1 this odd news item
of eventual immense importance:
"...Italian Software company[*] CINECA has compiled a MPEG movie showing not
only the external views and in car shots, but the actual telemetry output of
the FW16, moments before its crash." (March 17, 1997 AtlasF1)
* not a software company by the way. It's a consortium of 14 Italian
universities.
This wasn't nor could it have possibly been the "actual telemetry" from
Senna's FW16. Not even the Italian prosecutor had it, who as you can see
(because your site wrote it), was quite angry in court, two weeks after this
so-called FW16 "actual telemetry" mpeg came out.
That while thousands on the internet were downloading and being mesmerized
by this horseshit, Maurizio Passarini was hopping mad in court why nobody
gave him a data card (which didn't exist by the way), therefore no data of
the "actual telemetry" to present before the court.
All of the above is from your site, AtlasF1, and your choice whether you
want to defend its accuracy or admit that AtlasF1 simply invented it, it
doesn't matter to me. Feel free to challenge your own legitimacy if you
want.
The reason why it's impossible for CINECA or anyone to acquire the actual
FW16 telemetry from Senna's car containing the final 16 seconds of lap 7
data:
It was a "recorder," but not the near indestructable aircraft-style black
box which FIA only introduced after 1994, and this recorder and any data it
may or may not have contained was destroyed in the accident.
Williams never submitted this "very same telemtry [sic] to prove it was a
car handling issue" in court either. And has certainly never been conveyed
by your news. Nor is it found in your archive.
Their entire defence, which the judge agreed with and cleared of
manslaughter charges, was that the steering column did not cause the
accident but broke on impact.
Have a nice day.

But we'd never be able to determine if the driver eg. lost concentration for
a moment, hit a slippery patch of road, turned too hard at the wrong second,
hit something on the track that we couldn't see, felt a tyre suddenly go
off. Not that I'm saying that any of this happened just that there are a
lot of factors that can't be explained by rewatching tapes and calculating
numbers.

There were TWO data recorders.
The Williams chassis data recorder was damaged, and thus provided no
salvageable information. But data WAS successfully retrieved from
the Renault engine data recorder.
Unfortunately the engine data recorder could not be used to prove
conclusively whether or not the steering column failed. It did
record the various engine parameters displayed on the CINECA site as
well as lateral and longitudinal g-forces and pressures in the power
steering system.
The prosecution use this data in an attempt to prove that the crash
was caused by a steering failure. The defence lawyers argued that
the data could just as easily demonstrate a "car handling issue"
resulting from cold tires and low inflation pressures.
The data only proved conclusively that "something" caused Senna to
lose control as the car bottomed over that last bump, and that Senna
then braked heavily to significantly slow the car before impact.
Beyond that, the data did not prove the case for either the
prosecution or the defence. Hence the heavy reliance on the video
evidence presented by CINECA.

Wide-angle in-car video footage is notoriously unreliable for
arriving at any meaningful measure of "abnormal toe-in, toe-out".
When Jacques Villeneuve embarassingly spun off and hit the "Welcome
to Quebec" wall at Montreal a few years ago, and again when Michael
Schumacher crashed this year at Silverstone, many people were quick
to analyse the in-car video footage and pronounce each incident as
resulting from "definitely a steering failure".
It turns out that neither of those accidents was caused by steering
failure, proving only that you really cannot tell anything useful
about steering angles from a typical wide-angle in-car video shot.
I'm inclined to treat the "evidence" from the Senna video, as
presented above, with the same high degree of scepticism.

The charge of culpable homicide was filed _long_ before the Renault
telemetry emerged, of which I am well aware survived, which was handed to
the prosecutor who then gave it to CINECA. It did not, because of this, form
any foundation in the charge. The trial would've guaranteed transpired
without it. It wasn't what Williams used to defend against either. Their
case was that the steering was working before Senna's car left the road, and
that only the impact with the wall could have produced the required torsion
to break the column. A defence of which the Renault telemetry plays no role.
Williams used the 8 channels in the ECU set aside by Renault that
transmitted steering telemetry data in bursts beside the pitlane to
demonstrate the case. It was Charlie Whiting, siding with the defendents,
who commented on the Renault box telemetry and said that the steering was
working.
Remember, as well, that this telemetry, even if real, and even if it did
actually show a steering problem (it didn't of course), had no bearing on
the charge of culpable homicide launched at the track organizors and others
who weren't responsible for the car. To prove innocence required putting the
prosecutor's case in doubt regarding matters before the start of the race.
This telemetry is not in any originating manner Renault's either. At least
not subjectively. It's Williams's, because Renault transferred the only
remaining data on the recorder that was badly damaged and everything else
having been wiped, 11.8 seconds worth, onto floppy discs and gave these to
Williams, who handed them to the prosecutor. The discs came from Williams.
Renault underlined this point during testimony. Nor is this to imply that
Williams modified this telemetry. They didn't.
As already mentioned the charge of culpable homicide was filed long before,
so the telemetry means nothing. The charge was based on a 500 page report
(waiting for the report in reality), compiled under CINECA's leadership,
concluding that the most probable cause of accident was steering failure due
to a faulty and unauthorized weld. Although, where they got the evidence to
form this opinion is anyone's guess. Because it doesn't exist and never did
beyond the image of a broken steering column seen dangling from Senna's car.
The prosecutor, and CINECA synonymous to this function, argued their primary
case around the in-car video of Senna with his hands on the steering wheel.
The facts are CINECA altered the video sequencing of this camera angle and
every other. Admitting this, saying it did so to get a clearer picture. A
most misleading claim by an utmost partial academic opinion. That did so "to
favor the State Prosecutor interpretation." CINECA used "defocalization"
(their word) for Senna's onboard video. They brought the video out of focus
to help their case. The original video, which is obviously _better_ in focus
and shows nothing out of the ordinary, was useless to the "Prosecutor
interpretation." And so they brought it out of focus to create ambiguity,
potential, and the opportunity, which then happened, for "expert" testimony
to allege that the steering moves out of the ordinary in Senna's hands, 7cm
more in alleged fact. It doesn't, of course. Alongside the preposterous
testimony that the steering column was "70%" broken before the accident.
