Bluetooth-based system for automatically matching vehicle-mounted device with mobile phone terminal

摘要

The disclosure discloses a Bluetooth-based system for automatically matching a vehicle-mounted device with a mobile phone terminal. The system controls a vehicle-mounted device and a mobile phone terminal to turn on/off their respective Bluetooth function based on a vehicle ignition switch signal. In such a way, the driver needn't to turn on, match, and turn off the Bluetooth functions of the vehicle-mounted device and the mobile phone terminal manually. More intelligentized, convenient and efficient service is provided for the drivers and the power of the mobile phone terminal can be saved.
