After commenting on this question and realizing that the system is fairly complicated, I began to wonder how exactly Lane Keeping Assist works. While having service information does help some, it doesn't answer all the questions I had about the system or gave vague descriptions of the component functions.
So in short, how does Infiniti's version of Lane Keeping Assist work?
I'm more interested in the technical aspects of the system. If the steering input is converted to an electric signal, what's the process? How does the system know that the car is drifting out of it's lane? What sensors are involved? What modules are included in the system. Are there safety backups incase the EPS system goes down?
I don't care about the logic i.e. the math behind turning x input into y output.
