Do you know what the computers in your car actually do? Did you even know that there were computers in your car? Do you know why there are computers in your car or what they do?
Cars have evolved significantly since the first car was built long ago. Most of the changes that have come to cars over the last decade have necessitated a computer in the car, or at least a new sensor to relay new information back to an existing computer. Cars continue to become more complicated as new improvements bring new sensors and new computers into the car.
Some of the things that car computers monitor via sensors include oxygen sensors, air pressure sensors, air temperature sensors, engine temperature sensors, throttle position sensors and knock sensors
There are even more sensors on cars, particularly for luxury cars. The extra sensors in luxury cars usually have to do with the extra features that come in those types of cars. In the end, a lot of sensors are designed to relay information back to the computer that can then relay the information to you on the dash. An auto mechanic can also hook up to the cars computer and get more specific data. That specific data helps them to quickly and accurately diagnose the problem so that it can be fixed.
All computers for cars are designed and installed for a specific purpose. If you combine all of the computers and their purposes, they can be reduced to some general categories. Those general categories are: comfort, handling, emissions and performance.
There are 2 major computers on most cars. The ECM, or engine control module, controls all things that relate to the performance and emissions of the engine. The PCM, or power control module, has everything to do with the handling of the car including braking and traction control.
The engine control module is by far the most common computer found in cars. This is in large part, a result of a desire to improve the emissions of vehicles and the impact that they have on the environment. It also came about because of a demand to increase the fuel mileage of cars for the same underlying purpose of the environment.
For the end user, the use of computers in cars is almost invisible. Car computers work in the background while creating a better ride and a more efficient car. True, car computers are just one more thing that potentially will need to be fixed on a car. However, when all benefits and costs are considered, the gains from the computers in our cars far outweigh any negatives.

About the Author:
An engine control module and other car computers have been around for many years, but they continue to evolve as the get better for better results from our cars get better. There is no doubt that cars have improved with the use of computers. Safety, efficiency, and comfort have continued to get better as more computers and sensors are invented.
