What does a car’s computer do? Does it receive input from the car’s mechanical components? And if so, how?
In: Technology
Each sensor in the car reads something like fuel level or rpm of the engine, but just many, many more sensors. Each one returns a digital (on or off) or analog (a voltage range from 0-12V) and the cars many computers process those inputs. Other parts are controlled by the computer and are either turned on or off (digital) or controlled with variable voltage (analog).
This is oversimplified but mechanical components are controlled with actuators (motorized levers) or solenoids (electromagnetic push/pull).
