Abstract

The invention discloses an automobile intelligent key system based on a mobile phone storage extension card. The automobile intelligent key system comprises an intelligent key system controller (1), a vehicle-mounted Bluetooth module (2), an intelligent mobile phone (3), an electronic steering lock (4), an engine control unit (5), a door handle switch (6), a starting switch (7), a door lock motor (8) and a power supply relay module (9). The automobile intelligent key system is characterized in that a user takes a mobile phone intelligent key inserted into the storage extension card implanted with a secret key, and enters an automobile after the mobile phone intelligent key is communicated with and performs two-way encryption authentication with the automobile intelligent system through the Bluetooth module (2) and an application program on an intelligent mobile phone (1), so that the user can start or safely operate the automobile. The automobile intelligent key system can be applied after the storage extension card implanted with the secret key is inserted into the mobile phone, and the user can utilize the automobile without carrying a RFID intelligent key, so that the convenience of using the automobile can be improved, the secret key information can be effectively prevented from being stolen and copied, and the anti-theft safety of the mobile phone intelligent key can be improved.

Description

technical field [0001] The invention relates to an automobile intelligent entry and start system.
