Method for configuring vehicle control authority based on nfc device

Abstract

The invention discloses a method for preparing vehicle management and control authority based on NFC equipment, including the following steps: preparing an NFC module, the NFC module includes a single chip microcomputer and an NFC chip, the single chip microcomputer is respectively connected to the vehicle central control system and the NFC chip for communication and connection, and the single chip microcomputer is provided with useful information In the password storage unit that stores the unlocking password, the unlocking password has the authority to control the vehicle central control system to unlock and lock the vehicle; under the preset conditions, the NFC chip exchanges information with the user-defined card with NFC function, and reads The user defines the NFC identification number in the card and sends the information to the single-chip microcomputer; the single-chip microcomputer receives the NFC identification number and stores it in the password storage unit, so that the user-defined card has the authority to control the vehicle central control system to unlock and lock the vehicle. The invention can directly prepare a card or mobile phone with NFC function as a vehicle key, and has the advantages of high security, simple customization and low cost.

Description

technical field [0001] The invention relates to the technical field of near field communication, in particular to a method for configuring vehicle control authority based on an NFC device. Background technique [0002] With the popularity of NFC technology, many vehicles have begun to carry NFC cards as car keys to replace traditional remote control keys. However, due to the limitation of the NFC wallet function of mobile phone manufacturers, car manufacturers must sign a development cooperation agreement with each mobile phone brand manufacturer. Take BYD's NFC car key as an example, the new NFC car key jointly created by BYD and Xiaomi mobile phone is in support of NFC. Smartphone vendors associate BYD Cloud Service APP with Xiaomi Wallet APP. However, it is extremely difficult to develop with every mobile phone manufacturer to make the mobile phone manufacturer's app wallet support the car factory's NFC card issuance mode, which is almost impossible. Xiaomi mobile phone ...

Problems solved by technology

However, it is extremely difficult to develop with every mobile phone manufacturer, and it is extremely difficult for the app wallet of the mobile phone manufacturer to support the NFC card issuance model of the car manufacturer. Since BYD is not connected to Apple mobile phones, Apple users cannot drive BYD cars by swiping their mobile phones.

[0003] Now every vehicle that supports NFC function is equipped with two original cards before leaving the factory as vehicle keys, and users often have various cards that meet NFC functions, such as access control cards, bus cards, etc. Extended to car key
