It is believed that the first developers of the onboard computer devices became IBM-they installed their products on the BMW cars. However, the onboard computer has now become an integral part of modern cars. On many vehicle models, it is part of the basic equipment, although it raises the cost of the machine as a whole. So why does the driver have this expensive toy? Appointment

On-board computers are divided into universal ones, which are used for entertainment, navigation and Internet access. Others are also referred to as highly specialized-for example, diagnostic or route on-board computers. However, they are all referred to as the on-board.
In addition, the on-board computer can monitor engine performance: coolant temperature, oil pressure, air flow, and so on.
The text recognition system of the onboard computer can read out aloud SMS messages. If the message contains poetry, the system will handle them
In addition to all of the above, the on-board computer may notify the driver of problems and errors in the operation of the different systems: the engine overheating or the voltage in the power grid. Also point to an exceedance of the installed speed limit and to recall unfastened safety belts. Also, some of the onboard computers have the function of the desk clerk.
Modern on-board computers have integration with mobile phones-so the owner of the car can, for example, display the temperature in the passenger compartment or track the car's location directly from the mobile device.
Device and operating principle
The on-board computer is connected to the sensor chain, reads the information, then processes it as well as a regular familiar computer-using a special program installed. For example, if the computer has received information about gasoline consumption, the program may suggest mileage for the remaining fuel.
VAG, Mercedes-Benz and a number of other companies can program "behaviors" of dozens of different options, such as the central lock
There are also on-board computers, which consist of several computable blocks beyond their control, each with its own set of sensors. However, more often than not, there is a single digital system that combines all functions: diagnostics, navigation, management, and information and entertainment.
Displays all information on the display of the onboard computer, which can be of different types: numeric, three-or four-bit, monochrome, or color. To display 10-15 parameters, there is usually a 2-inch monochrome display and 128x64 pixel resolution. In multipurpose (multimedia) computers running the operating system, a high resolution color liquid crystal display and a large diagonal is usually installed.
It is worth noting that now the developers of the onboard computers are working in two directions. Digital technology companies specialize mainly in highly functional computers, such as multimedia, navigation and so on. And car manufacturers, in turn, seek to combine all functions in one central computer. Such a rich computer has its advantages and disadvantages. Plus, it costs less than a few mono-functional devices. On the other hand, if the onboard computer fails, the driver will be stripped of all programs. In all this, the most recent type is given to multifunction computers from the manufacturer. All modern car novelties already in the basic equipment have an onboard computer system that combines navigation, information and entertainment functions. Especially this trend is prone to hybrid and fully electric cars, as the most computerized.

However, if an amateur buys a car that is not equipped with an onboard computer, the advantages of highly specialized systems are in this situation. In many cases, this is because the multifunctional computer requires deep integration, especially if it has a diagnostic function. And it is often impossible, because it risks costly modifications to the main components of the car-for example, motor, electric system, transmission, etc. In addition, if the vehicle does not have a complex onboard device, you can buy computers as they are needed.
