Therefore, the bluetooth connection system provided by the embodiment simplifies the bluetooth connection and bluetooth disconnection operations of themobile terminal 2 and the vehicle-mountedterminal 1, and further, the bluetooth connection and bluetooth disconnection between themobile terminal 2 and the vehicle-mountedterminal 1 can be conveniently and quickly realized in the driving process of a driver, and the safe driving of the driver can be ensured.
The present invention is not limited to the above preferred embodiments, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
