Chinese New Year approaches automotive smart keys to improve vehicle safety

Among the many trendy electronic devices in the car, the smart key system is very eye-catching, and the keyless entry technology brings excellent convenience, and one-click activation brings a full technology taste. The stylish and compact appearance and high-tech smart keys have gradually become the pursuit of young people.

At present, many models are equipped with a smart keyless entry system that can be unlocked without leaving the key. The RFID-based smart key of RFID technology has a verifying action during the opening of the door. When the vehicle is locked, it will continue to send out signals. When the smart key appears in the signal range, there will be a In response, complete the checkmark behavior.

Integrated three functions The keyless entry system includes three basic functions: automatic unlocking, intelligent ignition and identifying the owner. Some brand models also have the ability to automatically close the windows after locking the car.

The function automatically unlocks the chip-sensing automatic switch lock in the smart card carried by the owner. When the owner approaches the car, the key and the car begin to exchange the set command information through radio waves. The car's shutdown and safety systems and the engine's control system are all activated. In other words, when you approach the vehicle a certain distance (usually 1 meter) the door lock will automatically open and release the anti-theft; when you leave the vehicle, the door lock will automatically lock and enter the anti-theft state.

Function 2 Smart Ignition Usually, the driver needs to insert a key into the ignition key hole of the car to start the engine. The smart keyless start-up method makes this easier. The function of the smart key is to make the engine recognize whether the operator is the owner and enter the standby state before starting at any time. When the engine needs to be started, as long as the smart key is in the area that can be detected, the driver can press the start button or twist the spin button to start the engine.

Even if you simply copied the key, you cannot start the vehicle without an ID code. Only when the owner enters the car, the car's detection system will immediately recognize your smart card. After confirmation, the car's internal computer will enter the working state. At this time, just press the start button (or knob) in the car. , you can start the vehicle normally.

No opportunity for anyone. As long as no one slipped into your car during this period, it was basically safe. Although there is no lack of violence, but which thieves are willing to pick a difficult vehicle to challenge their skills?
