Automobile NFC digital key implementation system and method, medium and automobile NFC digital key

Abstract

The invention provides an automobile NFC digital key implementation system. The system comprises: a digital key which communicates with an NFC card reader module and transmits data to the NFC card reader module; an NFC card reader module which is used for receiving the data transmitted by the digital key for authentication and checking whether the digital key has the authority of controlling the vehicle or not; a keyless entry and start module which receives authentication result of the NFC card reader module through a CAN bus so as to decide whether to execute start control or not; and an automobile body control module which receives an execution instruction of the NFC card reader module through a CAN bus. According to the invention, the production cost is reduced, and the authentication speed when a user swipes a card outside a vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a vehicle NFC digital key realization system, method and medium, and a vehicle NFC digital key. Background technique [0002] Car NFC digital key is a near-field communication technology based on NFC. Users use the NFC function of mobile phones or NFC cards to control the car. Car NFC digital keys generally include the main functions of using mobile phone NFC or NFC cards to lock and unlock the vehicle, and one-key start control of the vehicle. [0003] Deploy two NFC card reader modules on the car, one is deployed outside the car, such as the exterior rearview mirror, for user access, and the other is deployed inside the car, such as the center console, for one-key start function. Both inside and outside the car communicate with the NFC card reader module. The user uses the mobile phone or card to swipe the card outside the car. After the card reader ou...

AI Technical Summary

Problems solved by technology

The shortcomings of the aforementioned prior art are: first, the vehicle needs to deploy two NFC card reader modules inside and outside the vehicle, which will cause high costs; When swiping the card, the card reader outside the car needs to transmit the mobile phone or card data to the card reader inside the car through the CAN bus for authentication. Due to the low data transmission efficiency of the CAN bus, this will slow down the authentication speed when the user swipes the card outside the car.

Although this prior art has improved the success rate of NFC digital key remote unlocking and the business success rate of car owners using NFC digital key, it still has the disadvantages of the above prior art, such as requiring two NFC card readers, cost High; and the data transmission efficiency of the CAN bus is low, which will lead to slow authentication when the user swipes the card outside the car
