Hi, there are some cars (modern ones) that automatically turn off car's high-beams if there is any car in front of you.
My question is:
There are any possibilites to do that with our arduino & sensors ?
In order to be a good sensor it must accomplish the following:
-it must detect the car even if is with the front or the back, at you
-it must detect it from a considable distance(150-200m)
-it shoudn't turn off when you're taking a curve with car and the high-beams are reflected in some trees(really close to you) or others
I tried to figure it out by myself but the only thing that came to my mind was a powerful IR transmitter
with reflects itself on the car number plate and a receiver with some lens that can detect it.
Simply said, no it's not. In those cars a lot of heavy image processing (from a video camera) is done in order to make it work. So no, it's nothing simple.

Your could take the easy way, and buy a nice 1954 Cadillac.

How do those modern cars do it? Seems like the obvious thing to look up first.

The reason i posted this topic is cause i wanted to know your opinion about how this can be done using an arduino
It wasn't about opinion. You had an 'opinion' about IR sensors.
How do those modern cars do it? What sensors are being used? Seems like the obvious thing to look up first.
A quick google search here turns up that same paper at researchgate. That requires transmitters and receivers on every vehicle and doesn't even seem to consider the cars travelling in the same direction. That's obviously never going to happen.
The cars I've seen with automatic high beams also tend to have the collision-avoidance and adaptive cruise control features. That requires 3 radar units in the grille to detect cars ahead. Some use more than 3. I'm sure the headlights use that data in their decision process as well.
Cameras and image processing may be able to do 95% of the job of an alert human driver. But it's a multi-million dollar research project to get to even that level.
