Could always do body color on the "power bar" and leave the bowtie black. My bowtie doesn't look quite like that for some reason. I wonder if it used to have a shell on it that has broken off or something. My Avalanche is an '03 but cladded like yours. Mine is black and I am considering going all black.
OK. So I am back at it again
For the past few months I have been racking by brains on how to come up with a solution to use my 4 cameras in my truck not only as an around view system but also a system that will aid me (the driver) with minimal input from my end.
Basically I want to tie in the cameras to do what the rear view cameras of today do by switching to reverse automatically when backing up but to also incorporate the side cameras as a blind spot monitor without me having to physically switch inputs when I need to switch lanes etc.
It sounds easy enough just thinking about it but when you consider all that needs to be accomplished autonomously it does start to get mind boggling.
I am listing my thought processes here as I do cherish your feedback and input as I may miss some things while trying to make this work.
Auto Switching Cameras
Goal: To use one video input on my in dash monitor to automatically switch inputs when
1. Driving everyday
2. Backing up
3. Switching lanes or making right or left turns
This system is obviously going to be similar to a passive blind spot warning systems of today as I have no means or resource to do an active system.
1. System must not interfere with the driver when not needed ( must not be distracting)
2. User can disable system when not in use.
3. Process must not require any user input when engaged
*** I will update as it evolves. ***
For the most part it is simple.
Because I do not want this system to be intrusive, I am ruling out the option of an auto switching monitor as it may be good while backing up only however having the video input switch every time you change lanes, make a left or right turn etc. will make it really annoying when you have the same monitor for your in car computing needs.
This means I have 2 options
1. use an app that will create a video window on the PC and switch app on and off as needed.
2. Use the other video input on the monitor so system only seems to be on when user switches input.
I choose to go with the second option so that only when I switch to that input that the system will seem to function.
In the back end however the cameras will still be auto switching but just wont be seen by me.
To that end I may add a switch to turn the cameras off but that would to a point involve a bit more interaction from my end which I am trying to avoid.
So to solve this problem I will use one input, HDMI, for the PC and Video 1 for the camera system ........ for now.
That's the easy part.
Now this is where the fun begins.
This is where I was stuck for months until a brilliant idea just popped into my head
For the side cameras which I have in the side mirrors, my plan is to tap into the turn signal wires in my truck so that individual cameras in the side mirrors receive power only when the turn signals area engaged.
This has to be done somewhere in between the turn signal stalk on the steering wheel and the flasher module so as to get a steady current to the cameras when engaged.
If necessary, I will also add a diode to each individual connection to ensure that current flows one way only when a camera is engaged.
For the 2 side and rear view I went with a 10" 3 screen mirror it works well for this type of application. I am in the process of rewiring the back of my truck so no pics at the moment. Here is one during testing couple of years ago. SNO
I am using these as side view cameras
Thought about that SNO and researched it a lot but the whole theme of my build has been to avoid adding stick on parts to my build. If I could actually integrate that to my rear view mirror without it looking so bulky that would be fine but that is not what I want. Thanks for adding it though
After months of research I finally found the wiring diagrams for my truck which shows the connection and circuits to the BCM and underhood fuse box.
There are 2 point at which I can tap power for the camera in the side mirrors
At the under hood fuse box:
And under the dash
I am no good at creating circuit diagrams at this time so don't expect one from me but I am looking at this and in theory it does seem doable at least for my vehicle.
I plan on adding relays to actually provide power to the cameras rather than drawing from the current to the BCM
I realize that they do not draw a lot but since I will be connecting to my vehicle's BCM which I know can bring about costly repairs if something gets screwed up, I prefer to err on the side of caution.
I have seen mention a couple times now of a system someone is building to show an over head view of the vehicle for backing purposes. They use 4 cameras and a computer. I have seen this mentioned in more than one place. I am hoping to do something similar. I have also heard of a panoramic type view being created from 4 cameras and being able to move the display around. So you SHOULD be able to accomplish something like this at some point. You are much further along in your build than I am but I am researching this because I would like to do something like this myself.
I hear ya Rodney.
I also want to use mine as a passive blind spot detection system.
So when changing lanes on the highway and you put your turn signal on the individual camera can pop up on the display.
When backing up however I think I want it to default to the rear view camera.
I've tried the around view camera systems and in my opinion the novelty wears out quick.
You never get a seamless around view image as the individual camera angles are different and in some cases part of the images overlap.
This means you now have to take the time to figure out exactly where things are and it is a drag after a few tries.
I also considered a 3D camera with dual lenses at one point but so far those are just plain bulky even without their own hardware to process a 3D image.
Maybe sometime in the future.
