Why do Vehicles have so many Computers?


Modern vehicles are really quite revolutionary. Their ability to interact with drivers and other devices has made driving an extremely easy and comfortable experience. In order for all this magic to happen many microprocessors, sensors and other computers are placed throughout the vehicle to optimize the driving experience. These electronics are used for a wide variety of purposes, but each one serves a specific purpose. While some may only be accessories and others are part of important safety systems there is a good chance that if you experience trouble with any part of your vehicle it can be traced back to an electronic issue. While the main goal is to enhance the driving experience, here are three specific reasons today's vehicles utilize so many computers.

Exceptional Comfort

Many of the computers used in vehicles, especially modern European luxury cars, are part of an accessory that increases the driver and passenger comfort. These computers handle climate control, navigation, bluetooth connectivity, music and other entertainment. They also control memory features such as seat and steering wheel placement that may differ between drivers. If you experience a fault with one of the comfort features it is important to allow a professional mechanic to identify the problem using computer diagnostic equipment that can communicate with each vehicle sensor.


One of the greatest things about modern technology is that it's allowing for the creation of safer and safer cars. Microprocessors and sensors are used in many safety features that can be activated in a fraction of a second, including accident avoidance systems, assisted braking and ABS brake systems and they of course deploy the airbags the instant a collision happens, helping to reduce injuries to vehicle occupants. While it may be hard to detect a problem with these systems if there is not an emergency always be aware of your dashboard indicator lights. These lights, such as the airbag light and check engine light, may indicate an issue with these systems and it is important to have them serviced before it's too late.

Optimal Performance & Reduced Emissions

Sensors are used throughout the vehicle to ensure maximum power and fuel efficiency under all sorts of driving conditions. Parts such as the Mass Air Flow Sensor and Oxygen Sensor help regulate the amount of fuel being used and the EVAP system detects evaporating fuel vapors to prevent the loss of gasoline into the atmosphere. If these and other performance sensors fail there is a good chance the check engine light will be activated.

Computers and other electronic equipment are a great addition to the many systems of today's automobiles, but they can have their faults, which will result in a rough running vehicle or loss of comfort.
