Abstract

The invention provides a matching control method and system for an automobile Bluetooth key, a Bluetooth module in the Bluetooth key is in communication connection with a one-key start controller through a CAN line, and the method comprises the following steps: after the whole automobile is powered on, requesting the one-key start controller and the Bluetooth module to enter an extension mode anda safety mode; after entering the security mode, sending a key KEY request to the one-key start controller and the Bluetooth module for authentication; after the authentication succeeds, requesting the one-key start controller to send a key SK, and writing a vehicle identification number VIN into the Bluetooth module to obtain a vehicle identification number SC; and requesting the Bluetooth moduleto write the vehicle identification code SC and the secret key SK. Unsafe access is intercepted by setting safe access limitation, a first safety barrier is set, and double matching authentication isperformed on a vehicle identification code SC and a secret key SK through the Bluetooth module, so that good anti-theft performance of the Bluetooth key is ensured while unlocking, locking and starting functions of the Bluetooth key are ensured.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a matching control method and system for an automobile bluetooth key. Background technique [0002] With the improvement of people's quality of life, there are more and more cars, and the safety of cars has become more and more important.
