Car on-board computer - this is digital device, which receives information from various vehicle sensors, processes this information and displays the necessary data on the screen. At the same time, the functions of many models of modern computers go far beyond this scope. What are they - modern on-board computers?
Its main function is to indicate data such as average fuel consumption and distance traveled. The trip computer also displays the savings, storage and energy consumption for each trip. The time when we had to reflect on what we were offered is good and true. We offer a calibration system that allows you to customize the information displayed on the on-board computer.
However, what is more interesting with this system is that it allows you to measure average consumption in different ways and over a period of time that is strikingly long. Not to mention, the data can be displayed in real time, allowing you to know your average consumption without having to wait.

Types of on-board computers
By purpose, on-board computers (BC) can be divided into:
- Narrowly targeted - trip and diagnostic computers, as well as automobile electronic systems management.
- Universal - their functions additionally include a multimedia part, the ability to exchange data with the Internet, the ability to determine geographic coordinates, etc.
Respectively, appearance BC varies significantly. It can be from a monochrome two-inch screen to a full-size display built into the front panel.
Installation and configuration
Your car becomes, in a sense, your personal driving experience. The latter allows the driver to be informed about his driving by means of visual indications. Like other systems, it allows you to know the average consumption over a long period.
Various driver assistance systems, including those that manage fuel consumption, are becoming more sophisticated. However, this is not without consequences, as some cars have lost some of their sporty soul. On the other hand, cars are safer and more fuel efficient than ever with modern on-board computers.
On-board computer functions
The car computer can perform from several tens to hundreds or more different tasks... The simplest ones are displaying data on vehicle speed, engine speed and temperature, fuel remaining, mains voltage, etc.
The advantage of BC over standard indicators is increased accuracy and the ability to adjust. For example, when installing wheels of a different radius, the speedometer will calculate the speed based on the previous parameters, and the data in the computer can be changed, due to which the correct information will be displayed.
On-board computers provide the driver of the car with a lot of information about the vehicle, obtained from the data obtained using the sensors. Thanks to the growing number of components and electronic sensors in modern vehicles, this information usually goes well beyond the outside temperature or fuel consumption. Rather, it is a driver search information system that displays information on a screen in the driver's field of vision.
Previously, vehicles had traffic and distress lights to help the driver or even warn him of danger. This function is increasingly provided by the on-board computer today. For example, some on-board computers indicate brake wear or the number of seat belts that are not fastened, and the vehicle's current information systems often provide average speed data. fuel consumption and trip duration. In addition, the on-board computer has additional functions to control heating and cooling, radio or navigator.
Trip computers will report fuel consumption, distance and travel time. Moreover, they will not only give information about the actions already taken, but also calculate the estimated travel time and the required amount of gasoline.
The control computer controls the ABS, ignition control system, climate control, cruise control, parking sensors and a number of other system functions electronic control.
The calculations are based on data provided by sensors that are either already being used for other functions or are being added to the vehicle. Among the available sensors already in use for other purposes, these are related to the injection pump, tachometer and tachometer. On the other hand, brake wear sensors can be added specifically to the vehicle to provide specific information.
The on-board computer is responsible for evaluating and processing data from various sensors, displaying them in the driver's field of view - depending on the programming and settings of the manufacturer's parameters. Many devices are also used, combined or located in the center console. There are other alternatives for displaying on-board computer data, such as displaying on dashboard or projection onto the windshield.

Why do you need an on-board computer
We have already talked with you about helping drivers, the first step to autonomous vehicles, with this. You enter your destination on the onboard computer, and you have nothing to do. On the side european manufacturers we should always be happy with smart cruise control that brakes, accelerates and turns the wheel when it's on a fast track with well-defined lanes. At the same time, the current legislation does not provide for any cars that drive with a driver reading a book, it is useless to rush.
Some systems allow you to continue driving the car in the event of a sensor failure. This is achieved by replacing the sensor signal with a stored value (Fale Safe Mode).
Of course, you cannot drive like this for a long time, but in order to get to the garage or car service, this is quite enough. In the event of a failure of important sensors, the computer limits the dynamic parameters of the engine. BC of a car with an injection engine before starting the journey conducts automatic diagnostics and reports problems immediately.
It is ergonomic and intuitive. Your smartphone becomes the brain of your car. At least part of the brain, because it is only about music, telephony and navigation. On the other hand, the integration is excellent at the management level. Especially at the moment, although they are mostly available from premium brands, often loaded with high tech options and connectivity. Is there no duplication?
For this, you will additionally need
It's about a point of view. Smarter than a Mercedes? Free, this feature is powerful, smart, knows your workplace and your home, and you automatically take it in the morning or evening. It also correctly integrates the traffic issue into the course. He plugs in his smartphone and he's gone. The phone function is more of a summary.
Full-featured car computers, in addition to diagnostics, also perform entertainment functions that largely coincide with the capabilities of a standard PC. They run Linux and Windows operating systems optimized for use in cars. These devices allow you to fully use the navigation system, view photos or videos, play discs that are not recognized by most radio tape recorders, you can even play simple games.
With the advent of smartphones and other tablets automotive industry is finally considering integrating touchscreens into the dashboard for better vision and comfort. The car dashboard is a collection of instruments and indicators that inform and alert the driver. According to the models, the indicators are more or less abundant and more or less rich. It should be noted that some indicators are legally required.
Today, while there are still most cars with analog dashboards or a mix of both technologies, digital is gradually invading the interior, not just behind the wheel. While these “new” dashboards add personality, they shouldn't bother or complicate, a delicate exercise for the design departments that design them. The main purpose of these digital screens is primarily to inform the driver, but if before the driver had important information in front of them, the arrival of digital screens changed the game. from a smartphone or computer, you now need to “enter” and go to the system to determine the information you want to display.
Abroad they are often referred to as "carputer". By connecting a car subwoofer to a computer, you can fully use all the possibilities of high-quality sound equipment.

Most popular models
On-board computers are equally necessary for owners of cars of any class. Typically in expensive foreign cars high quality equipment is already built in. But manufacturers don't forget about the rest.
Most often chosen
It goes without saying that such manipulations can be performed while driving under the eyes to get out of the road with the consequences that this can provoke! However, if we go back to modern times? For car manufacturers and equipment manufacturers in the sector, the answer is clearly no. Behind the wheel, a 12, 3-inch non-touch digital display shows key speeds and engine rpm, separated by a compact roadmap. The latter can be displayed in full screen mode followed by two small counters.
Even owners of domestic or inexpensive imported cars can buy a car computer.
Most often they choose:
- Pilot is the only on-board computer that can be connected to carburetor Zhiguli models without much difficulty. For all its simplicity in management, it is quite functional.
- Virage Prestige has advanced functionality. Information about engine problems is displayed in the form of clear pictograms. The disadvantage is the highest price for devices in this segment (from 2 thousand rubles).
- MK-10 is the cheapest copy (less than 1000 rubles). But the capabilities are fully consistent with the price: inconvenient control, small display and lack of some basic functions.
- State - has several varieties. All of them are quite functional and easily connect to on-board network any injection vehicle.
- The navigator is a route-diagnostic computer that includes all types of electronic control units. Installation of an on-board computer of this brand is similar to the installation of the simplest devices.
From the models of the higher price category, Multitronix and Prestige can be distinguished. Car computer Multitronics has a wide range of functions (over 200). Access to numerous settings allows you to make it fully meet all the requirements of a particular car owner. For example, you can group the parameters shown on the display according to your preference.
The driver can select the information to be displayed using dedicated buttons on the steering wheel. Admittedly, it does not leave the road of the eye, but it is better to be at a stop for manipulation, at least at the beginning of the apprenticeship of the system. The first, located at the top of the dashboard, lets you control your infotainment, navigation, phone, internet and music.
As for the second, it happens where the ashtray and cigarette lighter are usually located. We feel vibration depending on the pressure applied to the desired function. In the competition, too, the dashboard will be digital, tactile and gesture. But the Bavarian manufacturer took the concept further. On the dashboard, a huge 21-inch long screen benefits both passenger and passenger. Since the distance between the screen and the passenger, the gesture commands are in place, or you will need to go through the touchpad located in the center armrest.
It can be installed on any injection or diesel car... One of the important features of on-board computers of this brand is the ability to control fuel quality. Based on the data of several trips, the parameters of the "ideal fuel" are calculated. At each refueling, the BC compares the filled fuel with the "ideal" one. If its quality is too low, the computer will signal this. Also, "Multitronics" automatically selects the optimal injection mode.
If not, the driver will be entitled to a "small" 7-inch screen. it is a wonderful exercise in style to see the day, in contrast to the technology it contains, and which should quickly find its place in future productions of the brand screw. With a 17-inch screen, Tesla is in abundance and keeps the competition at bay.
This is the text that the ghost of Big Brother leaves behind in French. Under this text, which has yet to be considered by the Senate, security forces "whose list is enshrined in the Council of State" will be able to access "embedded physical and digital data of the vehicle" to check if it is an Idea, Justice Minister Jean-Jacques said. Urvoas in front of deputies, was blown up by the inter-ministerial committee on road safety.
How to install an on-board computer?
Before installing the BC, you need to find out whether it is suitable this model for your car. Some computers are suitable for different cars, if you fill it with the appropriate software before installation.
The installation process itself is simple:
- Please select appropriate place... For example, on the center dashboard if there is a free Din seat or above the rearview mirror.
- Connect the BC input to the diagnostic block, and using the connecting cable to the K-line. Hide the cable behind the panel.
- Turn on the ignition, the computer should automatically pick up the data transfer protocol. If it doesn't, make your selection manually.
- Set the correct date and time. If necessary, in the settings mode, configure other functions (depending on the device model).
Car computer firmware
There are situations when bookmakers do not work quite correctly or with insufficient performance. This can be fixed with an update software... It is quite easy to reflash a car computer with your own hands if you are at least a little friends with a regular PC.
"No question about remote control"
Faced with this amendment, almost imperceptibly, motorists' rights advocates shout for massive espionage. Therefore, those who make our laws believe they can interfere with such private property. The wording of the amendment is very vague, which raises a lot of concerns as current technology allows newest cars log the speed, time of use, braking or even direction of the vehicle.
Checks can be made in the car
That way, they will know if the parts are of origin or not, ”he explains. “There is no question of remote control, which is technically impossible, but in fact the wording of the text is confusing,” he says. Pierre Chasseray of the 40 million motoring association also agrees: "The text voted absolutely stupid from the editorial point of view, it leaves room for all the observational fantasies." With this software, we recover very little speed-related data, says Emmanuel Barbet, and it would still be unusable, we can never prove who is driving.
For this you will additionally need:
- USB programmer;
- USB connection cable;
- The file of the required firmware version.
Depending on the model of the vehicle on-board computer and the USB programmer, the actions for updating the software may differ slightly. Therefore, when downloading new version carefully read the features of its installation.
To generalization of "black boxes"?
The amendment, if implemented, could help avoid large-scale fraud schemes for damaged and recycled vehicles, as was the case last September when it was prompted by the state. The idea of \u200b\u200bmore general control over the digital data contained in vehicles is not completely buried, but President of the League Against Road Violence Chantal Perrishon would like to introduce “speed, braking, turn signals or headlights” in every car to provide access to data.
If the data transfer process was interrupted due to sudden reasons, be sure to reprogram the BC from the very beginning. Otherwise, incorrect operation of the device or its complete failure is possible.
Some motorists consider the on-board computer to be an unnecessary electronic "gadget" that has little practical value. Of course, you can make calculations on a piece of paper yourself, and control the engine's performance "by ear". But a car on-board computer will handle this much more conveniently and better.
When correct use their cost will be justified, at least due to fuel economy. They will also help prevent serious engine damage, which will save it from expensive repairs. The choice is yours.
Somehow imperceptibly a new century began and accelerated - the age of information technology. And who would have thought, well, at least twenty years ago, that computers would take such a fundamental position in our life.
Today the computer has ceased to be a self-sufficient thing, causing delight and surprise, it is an everyday tool for solving a wide range of tasks. The computer has found a place both at home and at work.
And what makes a car worse? Moreover, for many, a car is a job, and often a second home. And in general, over the past few years, electronic filling has noticeably increased in automotive products, and it is increasingly difficult for a motorist to manage it alone.
It is for those who want to live in comfort everywhere and always, including in their own car, that a number of companies develop and produce special devices that can significantly facilitate the difficult life of a motorist. Such devices are called on-board or trip computers.
What the on-board computer can do
To say that the on-board computer is capable of a lot would be to say nothing. He is the brain of the machine and you can ask him what does not work in your car or does not fall within the specified limits of the norm. Although, of course, this is not a complete analysis that can be performed by a qualified technician, you can still find out most of the condition of the machine. The number of functions of a modern on-board computer is measured in dozens, and for some models exceeds a hundred. But let's not be unfounded and go through the main ones.
Instant parameters
The very first thing that an on-board computer is capable of is displaying instantaneous parameters: current time, vehicle speed, engine speed, engine temperature, temperature in the cabin and outside air temperature, remaining fuel in the tank, on-board voltage, etc. Many will argue that most of these values \u200b\u200bcan be seen from the indicators on the instrument panel, and they will be wrong. Reading accuracy standard systems leaves much to be desired, and most importantly, does not lend itself to correction.
For example, when installing larger diameter wheels, the speed of your car at the same engine speed will be higher. However, the stock speedometer knows nothing about your new wheels and will display incorrect information. While most on-board computers will allow you to make adjustments to the work and tell you about the true value of the speed.
Route parameters
With the on-board computer, information about the current fuel consumption, average consumption per 100 km, fuel consumption for the current trip, trip time, distance traveled becomes available. Some on-board computers can not only display information about a completed trip, but also help plan a new one. For example, they will report the time required to cover the path, calculate the recommended speed, report the required amount of gasoline or the number of kilometers that can be covered with the remaining fuel.
Control over the situation
The ability to see a number of parameters on the screen is nice. However, it is important not only to see, but also to react in time to an emergency situation. Here, the ability of the on-board computer to constantly monitor a number of parameters and, if necessary, promptly signal their change will be extremely useful.
For example, if the cooling system malfunctions or on just a very hot day, you may not notice that the engine temperature has exceeded the norm. In this case, there is a great risk of "boiling", which will ultimately result in serious problems for you and your car. The on-board computer will not lose control of the situation for a second and will immediately warn you about engine overheating sound signal - website. In the same way, it will monitor and warn about exceeding the recommended speed, about the value of the on-board voltage, about the need for regular maintenance.
There are systems that keep the car working even if one or another sensor fails, so that you can get to a car service or garage and fix the malfunction. The strategy is that if a malfunction occurs in the circuit of a sensor, the computer will replace the signal of this sensor with a constant value stored in the memory (Fale Safe Mode is the default parameter).
When entering limited control mode, the engine continues to run, albeit with less efficiency. Some control systems are so "smart" that the driver may not even notice that he continues to drive with a malfunction. Only a lit warning light indicates that not everything is in order with the engine, or its operating parameters do not correspond to the accepted standards.
In the event of a malfunction of especially important sensors that determine the operating mode of the engine, its efficiency and environmental friendliness, such as an air flow sensor or a pressure sensor in the manifold, a temperature sensor - the computer can limit the dynamic characteristics of the engine. After the fault has been rectified, the system returns to normal operation.
Service functions and engine diagnostics
For car owners with injection engines the on-board computer turns into a personal auto mechanic, who, before each trip, will diagnose the engine and vehicle components and report on the presence of problems and the reasons that caused them.
