PEPS technical principle of bluetooth key
With the continuous development of science and technology, the degree of intelligence of cars is getting higher and higher, and the PEPS technology of Bluetooth key has become an important technology in the automotive industry. This article will introduce the PEPS technology of the Bluetooth key from two aspects of principle and technology.
PEPS technical principle of bluetooth key
PEPS, Passive Entry and Passive Start, is a passive entry and passive start technology. Its principle is to control the vehicle through Bluetooth communication between the vehicle identification device and the key. The PEPS technology of the Bluetooth key can be divided into two parts: passive entry and passive start.
passive entry
Passive entry means that the owner only needs to bring the Bluetooth key close to the vehicle to automatically open the door. This is achieved by the vehicle identification device being installed near the door handle. When the owner brings the Bluetooth key close to the door handle, the vehicle identification device will automatically sense the presence of the key and automatically unlock the door. This process is realized through Bluetooth communication. The vehicle identification device sends an authentication request to the key, and the key replies with authentication information. The vehicle identification device verifies the legitimacy of the authentication information. If the authentication is passed, the door is automatically unlocked.
passive start
Passive start means that the owner only needs to sit in the driver's seat and press the start button to start the vehicle. This is achieved through Bluetooth communication between the VID and the key. When the owner presses the start button, the vehicle identification device will automatically sense the presence of the key, and send an authentication request to the key, and the key will reply with authentication information, and the vehicle identification device will verify the legitimacy of the authentication information, and if the authentication passes, the vehicle will be started.
PEPS technology of bluetooth key
The realization of the PEPS technology of the Bluetooth key requires the support of various technologies, mainly including the following aspects:
Bluetooth communication technology
The Bluetooth communication technology is the core technology of the PEPS technology of the Bluetooth key, which can realize the wireless communication between the vehicle identification device and the key. During the Bluetooth communication process, the vehicle identification device will send an authentication request to the key, the key will reply the authentication information, and the vehicle identification device will verify the legality of the authentication information. If the authentication is passed, it will perform corresponding operations, such as unlocking the door and starting the vehicle.
RFID technology
RFID technology can be used to identify the distance between the vehicle identification device and the key, so that the door can be opened automatically. When the owner brings the Bluetooth key close to the door handle, RFID technology can sense the presence of the key and automatically unlock the door.
hardware encryption
Hardware encryption technology can ensure the security of the communication between the vehicle identification device and the key. During the Bluetooth communication process, the communication between the vehicle identification device and the key needs to be encrypted to ensure the security of the communication process.
Software Encryption Technology
Software encryption technology can ensure the security of authentication between the vehicle identification device and the key. During the Bluetooth communication, the authentication between the vehicle identification device and the key needs to be encrypted to ensure the security of the authentication process.
PEPS Technology Application Scenario of Bluetooth Key
The PEPS technology of the Bluetooth key has a wide range of application scenarios in the automotive industry, mainly including the following aspects:
Automobile industry
The PEPS technology of the Bluetooth key has become an important technology in the automotive industry. More and more car brands are adopting this technology to improve the intelligence and safety of vehicles.
logistics industry
The PEPS technology of the Bluetooth key can be used in the management of trucks in the logistics industry, so that managers can better understand the driving conditions of trucks and effectively manage and monitor them.
Hotel industry
The PEPS technology of the Bluetooth key can be used for room management in the hotel industry, so that guests can enter and exit the guest room more conveniently, and at the same time, it can improve the security of the room.
epilogue
The PEPS technology of the Bluetooth key has become an important technology in the automotive industry. It can improve the intelligence and safety of the car, and it can also be used in logistics, hotels and other industries. It is believed that with the continuous development and improvement of technology, the PEPS technology of Bluetooth keys will be more widely used in the future.
