Ok, I’m going to jump right into this. My husband and I rented a car to make our family vacation trip from Texas to Florida. We were given a newer Toyota Camry, as we requested a car of similar size to our car, which happens to be a 2001 Toyota Camry. My mind was just blown by this car. My husband veered off the road just slightly, and an alarm started going off in the car. I am in my 30s with 2 teenagers, so I thought nothing could surprise me. I was wrong. As soon as the alarm went off, I jumped in my seat in excitement and asked if it was what I thought it was. We have now been playing with this system to see how it works. I had to pick my jaw up off of my lap because HOW DOES IT KNOW??!!?? When there is a slight bend in he road, we don’t use a blinker, but we turn the wheel ever so slightly, and it doesn’t go off. However, if we’re in a straight lane and we turn the wheel so the car moves into the next lane a little or into the shoulder, we get the alarm. It doesn’t come on when we use the blinker, and I understand how that would work, but I can’t figure this out, and I don’t understand any materials I’ve found on it, so someone please, ELI5!

There’s a camera in the top center behind the windshield. A software analyzes the videostream to detect lane markings and depending on the car also other things, such as pedestrians or traffic signs.
Some systems are better and some are worse. I’ve seen cars that can detect lane markings even in the worst conditions, while others already fail when the markings are worn out. In the end though, the system is usually as good as the software is.
Some cars use the lane system to also automatically steer and keep the car in the center of the lane. Also, a lot of cars combine the system with an adaptive cruise control that can follow the car in front of you and adjusts the speed automatically to follow the traffic. That system can either also use a camera, or radars that are mounted somewhere in the front of the car.
In very advanced systems, cars can also do automatic lane changes and fancy stuff like that.
