This device is called a ADAS camera. It has nothing to do with the FTIR windshield wiper sensor. That's a seperate part, and that needs to be in contact with the glass directly via a round puck of silicone material that is like an optical fibre. It's a seperate unit that sits next to the ADAS camera. The IR LED with the Fresnel lens sends out light to the car in the front, and the three photodiodes are used to read the reflection. The camera lens is an actual camera and all the image processing is done in the ADAD camera itself. Most automote chips are custom made for automotive use and part numbers doesn't lead to anything useful. Putting FPGA into super cost-sensitive applications like automotive doesn't make sense. It's probably an ASIC (the big, main heatsunk IC)
I've always pictured modern cars as being a bit like octopuses where the processing happens mainly at the edges of the network rather than at the centre as it does in vertebrates. The reason for this is that it's easier to sell things like smart lane control sensors if they don't require much to be added to the ECU. I could be wrong though and it would be interesting to see if the ECU has got smarter too.
would think it also harder to hack 20 tiny puters instead of one big control module as well. Not impossible, but definitely a more advanced degree of skill than what the average skull cap would have.
The three sensors behind the two big lenses seem to be photodiodes that just output one voltage/current. In this setup maybe for sensing oncomming headlights and dimming their own headlight to prevent blinding other drivers?
Those 3 sensors look similar to motion sensors in PIR lights which works on a zebra strips for motion detection, with 3 looking through 2 lenses could measure distance, collision detection maybe ?
Modern ECU's have even more processing power and control many and all sensors of engine, transmission, anti theft and more. Yes!! Please do an investigation of ECM/ECU!!
So lot of uncessary info at the start and once you opened it, searched few parts online. I was expecting more hacking cameras and processor and see how it does that
It's often a tough pitch to know who will watch these videos on TH-cam. It could be anyone from a beginer with a little curiosity, to a subject matter expert. As such, I have to try and cover all the bases a little at least! Unfortunately for this one, there is a lot of tech and backround information that the average person may not no, so yes, this did end up being a little "talking heavy" compared to the norm. By all means - if you'd like a follow up with more can bus probing about, or even trying to get some low level output from the board (J-tag etc) we can look into this, but I'd suggest that the algorithyms made by auto manufacturers will be VERY well protected!
An ECU doesn't contain much processing power. It's just a glorified state machine with a lot of I/O drivers. All the processing "power" is to be found in the safety equipment and infotainment.
I've talked to an ECU engineer before and the amount of work it does in a given second is astounding. A lot of task management, it takes a lot of scheduling to handle things like firing an injector. Imagine doing other things
When you think that they have crank position sensors, they must have a huge sample rate for that to be of any use for something that rotates in the 000s of RPM!?

These days, yes, that's probably a good analysis!
I'll see what we can find to see if it's on any interest!

I can believe that 1 may be, however why have 3 is an arrangement behind 2 lenses? What would be the beninfit to a sterostropic configuration?

@@a531016 you have done an amazing job so far, with what you have to work with, I know you will see it through.
back in the days TDA were audio amplifier chips
So lot of uncessary info at the start and once you opened it, searched few parts online.

Same. Want to see it powered up and analysing some IO

@@hayd7371 It will not do /anyhting/ without being connected to the rest of the CAN-network in the car.
It would have been nice to see what the camera sees.
My 2019 Honda one went out and they are over 1200 to replace, part alone is over 900. Crazy expensive!!!
Texas Instruments DSP?
An optical "car sensor"😂 Cruise control doesn't rely on the ADAS camera module that you mistook for a rain sensor buddy 😂
Yup - Lets look inside an ECU next!
I'll see what we can do!
