Automatic Temperature Controls (ATC) are complex systems incorporated into many newer car models. These temperature control systems take many different factors into consideration when setting and keeping the desired temperature inside the cabin of a car. Their systems use information from inside and outside of the car and look at the overall efficiency of the car and adjust accordingly. Simply, the goal of an ATC system is to keep the cabin of the car at its most ideal temperature. Let's learn a bit more about how these ATC systems actually work.
All of these different sensors and components are used in combination with each other to keep the car’s cabin and its passengers at the ideal temperature. ATC systems, in the simplest terms, does whatever it has to do in order to keep the car’s temperature at the specified level the passengers set it to. For instance, if you set the temperature to 72 degrees Fahrenheit, these systems work together to keep the car’s temperature at said level. It uses all of its different sensors placed in and around the car to keep its temperature in check.
This information the humidity sensor regulates how much air is aimed at the car’s windows to reduce fog buildup. Additionally, it also helps manage a comfortable climate within the car.
Similar to the temperature control systems, some humidity sensors use infrared sensors to measure the windshield and side window temperatures for further climate regulation inside of the cabin.
