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.
