Hey Dave These cameras are usually mounted behind the rear view mirror! :) hence the slanted shape to fit the form of the windshield
Completely correct. The angle would be much too steep for a lane-keeping assistant. In most cases, only the radar module for the collision warning system is installed in the bumper.
Yes. And the module is built to handle the 186-200`F temps. It's at the top, where the heat from the roof and greenhouse and direct sun all conspire to kill those caps.
I once worked at a PCB factory in the early 90's and built boards by hand by sanding, dipping, screenprint, galvanics, gold-plating...and many more processes, gold plating was so much fun, we used to bring in the most inane objects and gold plate them for fun without realising the cost of this stuff! I was 16 and fascinated with the place, closed down now unfortunately....hopefully not because of all my gold-plated furniture!
That is pretty cool! Did you at least get to gold plate all your cutlery so you can feel like a king while eating?
I would gold plate my bong
I would gold plate my weed.
I would gold plate my platinum. No wait! I wouldn't!!
Did you gold plate your member?
The most important thing I learn through this channel is the thinking process - that you do throughout all of the videos. And amount of details - incredible!
Thanks for doing this. :)
1:45 We're in, but not like flynn?
This was an awesome video. I am no where even close to being an electronics engineer but have been an ASE Master certified Auto and Diesel repair technician for over 30 years. I am gaining a strong desire to learn electronics and this site has taught me quite a bit as well as being very entertaining. Thank you.
Oh man, If i was a kid, the first thing I'd do with this camera is the exact same thing you did. "It's a spaceship! wooosh!"
Pigs in Spaaaaaace....
EEVblog big Muppets fan were ya ;) me too

You need to do a teardown of the Jaguar radar cruise control unit. It has a tiny parabolic dish steered by a servo motor. Scans back and forth to determine road boundaries and vehicle(s) ahead. Pretty amazing stuff.
good to 105C! holy crap, the water in your body would be boiling through your pores but that cap will still be just dandy LOL
remids me of the 'puddle jumper' in stargate atlantis.
yep, brings me back to my childhood days of making do with playing with what we found around house most of time, and using ones imagination :)
Having been involved in temperature riser testing of electrical devices for use in northern Australia, I can tell you that in a car under a windscreen on a 35°C day the temperature will easily reach 65°C or 70°C
I dare say 80°C would not be uncommon
Have you ever felt the steering wheel of your car on a warn day after it's been sitting in the sun?
Amazing Car Lane Camera. Quality is really good.
the phone PDF is actually a really clear way to view documents. thats suprising! works quite well.
Loved the Pigs In Space reference, Dave. Made my day!
Yes. I'm trying to do this with each new video or teardown if I think it would be worthwhile.
if i remember correctly, i think the camera would be mounted above the review mirror behind the windscreen. not in the front bumper
IT is. I have changed them in hyundais because of a recall and also when changing windscreeens.
SPC is ST's equivalence of Freescale's MPC range. (they have a partnership)
Same parts, different names.
I believe the 8 pin IC opposite side of the common mode choke is the CAN transceiver. The common mode choke is to cancel interference on the CAN bus.
This came up in my feed and I thought it new with the UBER incident fresh in the world...So it's a bit old, it's still good stuff. +5 for the Pigs In Space reference! Kids today have no idea what they are missing! LOL
The wikipedia article for lane departure warning system uses a screenshot from this video.
I just happened to see these yesterday -- yes they are beneath the side mirror(s) of the car, facing to the rear of the car. Makes sense as facing rearward they are much less likely to get dust and bugs on the lenses that way.
Hey Dave, if you or the person who sent that to you has an approximate year make and model of vehicle that came out of, some of the auto mechanics in the chats and forums could look up description and theory of operation on a service such as Mitchell ProDemand. Perhaps even a Hyundai service manual.
A previous comment was correct... they are mounted at the top of the windshield next to the rear-view mirror. Extremely hot location!
Thank you
That's a really great idea!
Thanks, I liked that. Good video. Very Informative. :-)
You're right. I was on a smartphone and had no hope to read the numbers. But the common mode choke is used for CAN, so seeing the closest 8 pin IC. :)
CAN should have a separate transceiver, either 8 pin or a fail-safe 14 pin version.
hi Dave
Love the PIGS IN SPACE Reference hehe
hey... that watch
is that by any chance one of those RED Transformer watches that you used to be able to click off your wrist with 2 buttons and it actually transformed into a robot hehe
you know the one i'm talking about... right
the one that came after the Casio Calculator Watch that you could store your friends phone numbers in.
Looks like that sort of a watch
I always love the way dave pronounce hyundai. Hi, Undye!
Qorivva as I found out, is a Power PC architecture.
So, similar to Game Cube or pre-OSX-Macintosh.
OSX was originally PowerPC, they switched around 2006ish... en.wikipedia.org/wiki/Apple%27s_transition_to_Intel_processors
@ 10:24 - "And what is that gunk stuck to my esd-mat?"
That made me laugh. Thumbs up on the video just for that ;-)
Depends what part of the vehicle inside the engine compartment temps close to and above 212*F can commonly occur which is why ignition modules and voltage regulators are common failure items.
Anyone can tell why some people like those layer marks? It seems that would make sense to see those marks during the PCB manufacturing or in some case that you are peeling off layer by layer. Is there any other reason for those marks? I see them a lot.
There are probably clock multipliers in the chip, so it does not actually run at 10MHz, but for some applications, 10MHz is a lot.
Episode 556 we progress to the dual timer IC :P Going to be a wait before the 741 op amp tutorials though.
Very interesting video. Also because "Car" Technologie is always a little different then, well, i'd say "standard day to day electronics", because of the safety requirenments. Cool video :=)
I spotted a Coil-Craft inductor...great stuff.
Was not expecting this level of quality from Hyundai. Wonder if this is from an Equus or a high optioned Optima.
probably same on both
You'd be surprised at the quality of computers in most modern cars, they have taken major steps forward in build quality and general design as of late. It was once that I would complain about every car computer I had to work on outside of a Lexus. Now the build quality is so insanely good that I doubt we'll see electronic issues outside of rubbed wires/software glitches before the engine finally needs rebuild in modern cars. If you look at old isuzu computers and compare them to today it's chalk and cheese and this is a good thing as it means I don't have to test so many god damn capacitors.
Was that part actually made by TRW? You would be surprise how many parts in your car might be made by them. They even make brake pads, various electrical parts, and seat belt components just to name a few things that I know of.
s0nnyburnett Hyundai does make some great quality cars now. They're far from mediocre ugly sendans they used to be.
foxman105 Some Chevrolets were Hyundias really. Some of them are also Toyotas which are very similar to Hyundais and some of them even use the same parts.
Just wanted to point out that the Freescale chip has PowePC core, like most (all?) of their automotive products. They have been doing these automotive chips quite a long time and have well respected and highly reliable chips.
so to sum it up,
Image sensor
MIPS32 based DSP
PowerPC based co-processor & CAN controller
DRAM
Flash memory
Haha! I know all about this I worked on it.
It is from ZF - or TRW back in the day. That is my groups design. I was in the DAS group (driver assisted systems).
Nice :D with how many people and for how long did you work on this? :)
@@johnuferbach9166 very small team like 2-3 (2 hardware 1 mechanical) . ME provide all the software and algorithms for this, they have a whole team of people in Israel working on this. I guess I should say Intel now...
Google Hyundai and capacitors in electronics and you find they used to have a pretty high failure rate in ECU models in the beginning. Caused a few issues on older cars with engine management units failing just out of warranty.
Hi Dave, I stumbled on this video... anyway wanted to let you know that "Qorivva" is a PowerPC architecture MCU targeted, of course, towards automotive stuff. Nothing fancy, just marketing.
what tablet are u using?
Don't confuse 10K hours at rated temp and current, with it's actual operational life.
The dash of a car, where this unit is intended to go, can reach 190F while parked. I don't see how these units will be reliable in phoenix arizona.
@@FelonyVideos the caps are rated over 212°F
I can't believe I keep watching this stuff on a somewhat regular basis.
The content is the utmost, total overkill for what I'm capable of comprehending.
I've yet to see anything being discussed that would be of use to me - ever.
What the hell is going on with this channel.
same here. eevblog magic!
Freescale is BIG ins automotive. Many inyection computers runs on Freescale MPC micros. In fact, they have an special flavour with peripherals just to enhace precision at reading and engine's calculating camshaft and crankshaft position. You cannot simply beat them in its habitat. Guessing that some early 68000 has this facility included and ECU makers turned to Motorola.
There cameras are mounted outside of the vehicle, usually in the wheel arches, so the temperatures won't be as extreme.
Dave, i've noticed some interesting stuff in the text you might have not noticed:
@25~ min it says it's in production SINCE 2010, so it's not from 2008 and that there's an eyeq3 in production, 6 times more powerful
what brand is that?
MIPS and Power on the same board. Lovely.
Would it be possible to get a signal out of that directly?
I drew up a split CAN terminator for a board less than a year ago and looking at that funny CML and resistors at 15:00, it looks just like one. Funny values, though. It could just be filtering for a differential line with that cap to ground point.
liionbms.com/php/can_bus_termination.php Here's one scheme like that.
Better digital.ni.com/public.nsf/allkb/C03609ECFF16A14E86256E5A008293EA
yeah the case would be about 2 years.. My 06 volkswagen jetta died in 2012 (did the engine rebuild myself just last week) while my 02 Chevy Silverado never changed oil/filters, injectors etc since i bought it in 05, and its still alive today...
They already recognise speed limit signs. I can turn on the auto speed limiter in my car. It's quite handy actually...
The architecture isn't Qorivva it's IBM Power architecture en.wikipedia.org/wiki/Power_Architecture
It's some pretty cool stuff, just only used in embedded systems and corporate server environments.
The opening few seconds had me geeking out lol. Don't grow up Dave it's a trap!
Did you put a picture of this up to wikipedia ? :)
Picture looks like your working mat and "Camera model: Canon LEGRIA HF G10" sounds familiar.
I like it.
I had to pause for a second to make sure that the data sheet did not, in fact, have the (non) word "complexibility" in it.
Why are the vias untented?
TRW Conekt (conekt.net) is the external consultancy arm of TRW Automotive. On their site you see more about test facilities and stuff.
Also something about a T Cam+. Looks like the next model of this lane guidance camera. Shows a small list of technical spec in a pdf but again hardly any info (see T Cam+ under sensing products).
It would be nice to have half an idea of what a lane guidance camera is trying to do.
Left left, straight straight right sort of thing?
I'm interested in this concept of "complexability", Dave.
You saved me the trouble of responding to the troll. He/she thinks "lazy" is synonymous with keen!
More automotive teardowns!
5:00 Nope, this sits inside the Aircondition passenger cabin in the middle-top of the windscreen overlooking the road ahead.
They are usually in the rear view mirror. Kind of a pig to change when they are recalled.
How would you reverse engineer a 10 layer board? Or a 4 layer board for that matter?
Separate the layers of course. Not an easy task but doable. Have to take images at each stage and clear all the vias of solder before separating them.
Dave, If i can get a year make and model of the vehicle that sensor came off of I can print a schematic and pin out.
They are mounted where the rear view mirror is
part number had 24c ... 24c.xx is usually serial eeprom, which usually comes in 8 pin packages, the st-eye chip has built in can bus as shown on its data sheet later in the vid, I'd bet a $ it is a serial eeprom
They seem to be using ARM's AHB bus matrix in the Freescale chip. Interesting...
Dave sounds like Chewbacca in this one, especially starting at 12:40
Can you scrounge a few boards of the decommissioned petaflop supercomputer 'Roadrunner' for a 500th episode Teardown Special'??
Mobileye is a very cool Israeli company with a very interesting technology to keep drivers and pedestrians safe.
myyoutubeusername ... though cyclists not so safe? :-)
gorillaau actually the Mobileye warns drivers of cyclists as well!
I'm reasonably sure the version 5 & 6 of this system are part of tesla's autopilot system too
Is it proprietary? It's marked as as an AMP 185740-1, and shows up on Tyco's website. However, no distributors have any stock. Online components will let you order it, but the lead time is 8 weeks. Blech.
Considering the amount of safety necessary in these, I'd hazard a guess the five processing cores are each sampling a different area of the camera picture, and overlaping with each other - that way you have some redundancy should a processor core become corrupted. But it's just a guess; "I'm no expert!"
Well, it's not supposed to go beep beep under normal circumstances. At the point where you're about to fall asleep and drive onto the oncoming lane, you'd probably prefer to have your car beep at you.
That actually seems like it would be a very poor mounting location as it'll stop working after the first mud hole until you hose it off.
These are located behind the windscreen below the rear view mirror.
Really nice teardown. Was already looking on ebay if I could find such a camera :D. Would be nice for my electronics project. But unfortunately ...
Found the manufacturer: trw.com/sub_system/camera_technology
Some specs and features can be found in the pdf they have on that page.
Alas, not much technical info.
Even if the cap was working at max rated temp and current during its life cycle, and lasted the 10k hours, and if over that 10k hours of driving your average speed was 30MPH that would be 300,000 miles on the clock.I would imagine there would have been a fair bit of replacement to the mechanics of the car, prior to you having to worry about the caps.
The applied voltage is not really relevant,the heat and amount of charges/discharges per second usually wears it out so much faster.
Those caps would do as good for 5VDC as they do at 35VDC,doing nothing.
If you sell cars, Do you want people to bye one every 20 years or every 5-10 year?
Dave this thing would live above the interior mirror
do you keep you pcbs from teardowns? you must have a lot
Aluminum/aluminium doesn't "rust" but does corrode.
Not sure if that's entirely true. They used acrylic lacquer in 40s all the way to 60s. It's quite brittle and not quite durable either, specially if exposed to UV and water (not very environmentally good either). Then in 60s they switched to acrylic enamels which were better but still very brittle in today's standards. The only good thing in acrylic lacquer was that it was extremely easy to repair. But sure those paints lasts long if you keep them indoors.
looks like the puddle jumper from stargate
So magic elves? Thanks! ;)
And people wonder why the parts on their cars cost so much. They aren't just some one-off hobbyist stuff. They do massive R&D and then make them on an assembly line. 4:2:2, nice.
you can do sooo much with that technology, can you not?
Most cars still use steel body panels you can test this with a magnet.
just the connectivity interface chip has the processing power of the Power Macintosh 6100 I used at university. God I'm getting old.
and the quantum chemistry department probably used a similar spec chip in their massive IBM RS/6000 type workstations. Now we have 1990s supercomputing power in a mobile phone or a 300 dollar option for your car...
If you want your mind blown have a look at some of the TINY purchasable IC's that some people put on their projects
It's mind blowing that all they need is a resonator and some caps to work
LGU unit probably mounted top of windshield inside the cabin
Australia has consumer laws that prevent this sort of forced failure.
Not so, you are now thinking about air temp. Car's body on a sunny day may heat up to 60-80 Celsius degrees with ease. It's the same thing as you can't leave your dog inside your car on a parking lot.
These cameras are always mounted on the windshield right behind the mirror.
No doubt, lots of blind vias on that very dense PCB
The first car manufacture to make a car that disobeys it's driver would probably end up going under as people would demand their money back.
