There are computers in almost every single car on the road today. They are responsible for a huge range of functions from monitoring and regulating the engine to providing in-car entertainment and information. Sometimes called Electronic Control Units (ECUs) these computers use a variety of sensors to monitor different systems in the car and make decisions based on the data they receive.
Just how many computers are in a car? It depends on the make and model but a typical car will have around 50-100 ECUs. The most complex cars on the market today can have as many as 150 ECUs.
The majority of these computers are dedicated to specific tasks. For example there will be an ECU for the engine one for the transmission one for the braking system and so on. However there are a few general-purpose ECUs that handle tasks that are not specific to any one system. These include the body control module (BCM) which controls functions like the interior lights and power windows and the infotainment system which controls the car’s entertainment and information functions.
So how do all these computers work together? Most cars use a network called a Controller Area Network (CAN) to connect the different ECUs. The CAN allows the ECUs to share information and data and makes it possible for them to coordinate their activities. For example if the engine computer decides the car needs more power it can send a message to the transmission computer telling it to shift to a lower gear.
The increasing number of computers in cars is part of a trend towards what is known as “vehicle electrification.” This refers to the process of replacing mechanical components in a car with electronic ones. For instance cars today often have electric power steering which is much more efficient than the hydraulic power steering systems of the past. Electric power steering is just one example of the many ways that computers are making cars more efficient safe and comfortable to drive.
