What is the difference between the electronic anti theft of the engine and the iron general anti the

Hello, the engine electronic anti-theft is locked from the inside of the computer, and the iron general anti-theft device installed later is anti-theft by disconnecting the oil circuit, so the engine electronic anti-theft is more advanced.

Hello, the engine electronic anti-theft is the internal anti-theft of the computer module, and the iron general is mainly the central control door lock anti-theft, of course, the iron general also has the external anti-theft of the oil pump relay,

What kind of model, generally the current original car electronic anti-theft is controlled by the computer version, and the additional is controlled by the iron general control box.

The engine electronic anti-theft is an internal anti-theft that is more advanced.

Engine anti-theft is to make the engine not start.

The engine itself is equipped with an electronic anti-theft function that follows the car computer, but it is an anti-theft device.

Engine electronic anti-theft is a set of anti-theft system installed on the engine, commonly known as engine anti-theft locking system. For cars that are already equipped with an engine anti-theft locking system, the car thief will not be able to drive away even if the car thief can open the door.

The engine anti-theft locking system is developed on the basis of the general V ATS, and inherits the idea of VATS in the anti-theft principle, that is, the password of the chip in the key is matched with the password in the starting electric door to control the starting of the engine to achieve the purpose of anti-theft.

This function has a great effect on vehicle anti-theft, without engine anti-theft of the car, others pry open your car door and enter the car, you can directly start your car by wiring and then drive away.

If someone else enters the car with anti-theft, even if the wiring is correct, it will not start your car, and it will turn off immediately after starting, because the engine power module will not supply power to the engine to supply fuel and fire (high-end cars directly lock the transmission), and the car with anti-theft is safer.

So of course it is important to have an electronic anti-theft of the car engine, otherwise everyone can start your car. @2019

When we buy a car, we often hear the salesperson say "engine anti-theft" to us, but I don't think many people know what it means. Today, we're going to follow the Lord's question. Let's take a closer look at the features of "Engine Anti-Theft".

The first thing to say is that engine anti-theft is not a configuration invented to prevent engine theft, but a device to prevent vehicle theft and make the vehicle safer. Now that we understand what engine anti-theft is, let's take a look at how it works and what it does. Here's how the engine's anti-theft locking system works:

There are electronic chips in the ignition key of the car, and each chip is equipped with a fixed ID, such as our ID card or fingerprint, which is only one per person. That is to say, only one key can start the engine, and only the ID of the key chip is consistent with the ID of the engine side, and the car can start normally. Conversely, if the key and engine ID do not match, the car will immediately and automatically cut off the circuit, making the engine unable to start.

In this way, even if you open the door and enter the car, you will not be able to start the engine and avoid theft. After listening to the above introduction, many riders may feel fortunate at this moment, but I would like to kindly remind all old drivers that although the engine electronic anti-theft has improved the safety performance, the engine electronic anti-theft is not 100% safe, especially for luxury brands. Some theft gangs use special instruments to copy keys with identification chips.

Therefore, it is advisable to park your vehicle in a supervised or monitored parking lot to prevent theft. Some people may say, how can you get the right key if you lose your key? In fact, there is a confidential envelope with the PIN code of the engine electronic immobilizer in the owner's manual.

When the key is lost or the anti-theft converter assembly is damaged, you can give this envelope to the distributor to match the appropriate key.

{{Do not disconnect the car battery casually for more than 2 seconds, even if you connect it again, the anti-theft system does not work, and is in the initial state,!! Who said BMW, Audi and other high-end car anti-theft systems still work! When you run short of the battery, the anti-theft system will automatically enable the self-contained battery and start working.

No problem with the principle analysis! Courtesy.

BMW, Audi, Buick and other electronically controlled cars are the anti-theft systems that come with the original car, and there is a main integrated chip. The electronic immobilizer represented by the "Iron General" also has an integrated chip, in which several "doors" are designed, any of which "doors" are triggered to open, and a high potential will be output to the driving circuit, and then to the actuator, which can be a relay, a thyristor, a power triode, etc. For example, after the triode is turned on, the alarm circuit can be energized, and the wire can be connected to the small horn in the front cover of the car to make the alarm sound.

The aforementioned "door" triggering is done by using sensors, that is, the switch is wired triggering, so the reliability is greatly reduced. Some electronically controlled cars use infrared sensing in the car to detect that someone has illegally entered the car, but this infrared has a fatal defect, when the temperature in the car reaches more than 3 degrees, the infrared detector loses its effect, this is because the detection chip is also the same as the ambient temperature, and the temperature of the person is close to the ambient temperature. In the summer sun exposure of the car, the inside of the car has reached 4 degrees, and the infrared detector is completely useless.

The principle of the car immobilizer also includes the power supply system, which is powered by the car battery, do not disconnect the car battery casually, more than 2 seconds later, even if it is connected again, the anti-theft system does not work, and is in the initial state, which is equal to the anti-theft without fortification.

Do you want to steal the car, even if you get it to make it not ring, there is no car that must be unlocked. Otherwise, the power of the starter system will be cut off and the power supply will not be provided. The electricity on the road will also be cut off, and there will be no oil supply. I can't start it.

My central co-pilot can control all the doors. What's wrong with the driver's seat.

It's still a bit useful, install the engine electronic anti-theft, if someone wants to steal the car, the anti-theft system does not detect the key information, then the thief can't start anyway, which also plays a protective role.

It is useful, because now many people will do anything to steal the engine of the car for their own interests, if the engine also has electronic anti-theft, then the safety of the car is a very good guarantee.

Electronic anti-theft is very useful, even if the line is correct, the car cannot be started, and even if it is started, it will be extinguished immediately, because the car computer cannot receive the correct key signal, so electronic anti-theft is very useful.

I think it's useful because there are also a lot of people who steal engines nowadays, so installing an anti-theft device can make the engine more secure.
