Types of control codes in car systems

22.03.2024

There are three types of control codes of auto -signaling: static, dynamic and dialogue. Consider each of them.

Static codes

Auto alarm with a static code will not be able to provide a high level of car safety, because from the name itself it is clear that such a code is constant, and the length of its variable part leaves much to be desired (2-8 bits).

Dynamic codes

Such codes are the most common type of codes today. The principle of operation of dynamic codes is to generate a new code, each click on the Belok button. However, no matter how diversity and complexity these codes are different, they all obey a certain law that ensures their synchronization when random presses on the key fob buttons outside the zone of communication with the car. There must be synchronization of the main module and key fob, otherwise there will be a breakdown of the signaling and key fob, which will lead to the keychain to control the system.

The descriptor, that is, the law of code change with each next generation, is constant for all auto -signals of each model range. This is necessary to ensure the possibility «&Raquo; new keychain of the initial signaling model in case of loss of old.

Dialog codes

Of all the possible options for alarm alarm with the dialogue type of encoding, the most resistant to a hacking system today.

The principle of operation of the auto -signaling with dialogs is as follows:

When you press the button, the keychain gives out its individual ID-number, which takes the base unit;

If the ID-number of the key fob is identified as its own, then the basic block gives out the code executed according to the dynamic law;

The keychain accepts the sent code and encodes the desired command (the team is activated by pressing the button on the key fob), and then sends it back to the base unit, which, in turn, decodes the accepted command and performs it.

The base unit sends a confirmation of the command to the keychain.

This principle of coding seems to be the most reliable, and therefore experts have serious reason to believe that dynamic identification will soon supplant the remaining types of encoding from the market.
