Nowadays, it is practically impossible to imagine a car without electronics, which can be divided into groups according to purpose: engine control, motion control (transmission), increasing traffic safety, providing comfortable conditions for people in the cabin.
Vehicle management systems (for example, D-4, DME, DDE) make the car more economical and environmentally friendly, increase engine performance and promote smooth operation, and some of them even monitor the condition of the battery.
Electronic vehicle control systems include an automatic transmission, adaptive cruise control, and a parking assistance system. The rapid development of electronic car systems is gradually making the creation and use of autopilots a reality.
Electronic car control systems
Traffic safety enhancement systems consist of:
- anti-skid system, which prevents the wheels from slipping, which is especially important during sudden acceleration or driving uphill on a slippery road;
- anti-lock braking system, which prevents the wheels of a braking vehicle from locking and maintains its controllability and stability;
- a differential lock system, which increases the overall safety of the vehicle, improves its traction characteristics, facilitates the moment of starting and climbing, and ensures intense acceleration;
- a brake force distribution system that ensures effective traction of the rear wheels and prevents them from blocking and skidding;
- hill hold system and descent assist system;
- braking assistance system, it is activated in cases of emergency braking when the brake pedal is not pressed firmly but sharply. The principle of operation is to increase, if necessary, the pressure in the brake system;
- exchange rate stability system designed to maintain vehicle controllability and stability during maneuvers.

Main types of electronic automotive systems
The main types of electronic automotive control systems include:
- EU braking system;
- Electronic steering;
- Electronic throttle position control system.
Read about electronic immobilizers. And also about why ABS is needed?
In a car that has a full-fledged electric brake control system installed, there is no mechanical connection between the brake system and the brake pedal itself. When you press the pedal, an electronic switch is activated, which, through the efforts of a mechanical drive, applies the required level of braking.
The auxiliary systems of a modern car include automatic headlight switching on/off, a rain sensor, a car navigator, and tire pressure monitoring. Not all of the above vehicle control systems may be included in the basic equipment on production vehicles, but they can be installed additionally.
Thanks to electronic vehicle control systems, the mechanisms and components of the car have become more reliable, and the vehicle itself is safer, but it should be remembered that the driver must still correctly and quickly assess the situation on the road, react quickly and soberly.

Electronics in a modern car
Each new generation of car or truck contains an increasing number of electronic systems and sensors. All this electronics is designed to improve the handling, comfort and safety of the car. But increasingly complex systems are forcing car service technicians and dealers to increase their technical potential. After all, it is not possible to find and eliminate the cause of a malfunction in a complex computer system without special diagnostic equipment. Today, even banal speed meters, which previously consisted of a mechanical rotating cable running from the transmission to the instrument panel (speedometer), have been replaced by electronic speed sensors. The operation of the speed sensor is quite simple and is based on magnetic processes that create rotating parts in the transmission. The wire from such a sensor goes to the instrument panel, where the electronic signal is converted into speedometer readings.
Today, even the air conditioning system in any car has not one sensor, but several, plus a “smart” control unit. All these sensors evaluate the temperature in the car's interior and transmit data to the control unit, which in turn supplies cooler or warmer air into the cabin, optimizing air flows and controlling their speed. But this won’t surprise anyone.
Now the world leaders in the automotive industry have taken the path of making cars even more complex. In a premium car, you can choose the driving mode, the comfort of the suspension or the dynamics of the power unit and transmission operation. As a result, you customize the entire car for yourself. The concept of a mechatronic chassis appeared. This is when the car itself begins to adapt to the quality of the road surface and other current operating conditions, partially taking on the functions of the driver.
In some models, the absence of a mechanical connection between the steering wheel and the turning wheels has become the norm. The electronic system of the car itself determines how to turn the steering wheel based on current data from many sensors. Sometimes this not only corrects gross driving mistakes, but also saves the driver’s life.
Remote parking, when a car is parked without the driver's participation, is no longer a fantasy. Cruise control with acceleration and braking functions, all this is real. The next step in the development of automotive electronics will be the creation of a full-fledged autopilot. All leading manufacturers are actively working on creating such systems. According to the calculations of some industry analysts, by 2020, cars that will drive on public roads without a driver will become commonplace.
