Embodiment 1

[0037] Such as figure 1 and figure 2 A low-cost interconnection system between a mobile phone and a vehicle is shown, including a mobile phone 5 and a vehicle, at least one APP program is installed on the mobile phone 5, and the vehicle includes a vehicle radio 7, a loudspeaker 1, and a Bluetooth interconnection module 6. Bluetooth interconnection button 2 and microphone 3, but the car machine does not have ARM chip, RAM, ROM and display. Described loudspeaker 1 is connected with car radio 7, and described car radio 7 is connected with bluetooth interconnection module 6 by CAN bus, and bluetooth interconnection module 6 establishes communication connection with the bluetooth module of mobile phone 5, and described mobile phone 5 is connected to control car by the bluetooth of establishment. The radio 7 tunes the frequency and adjusts the volume. The car radio 7 controls the APP program on the mobile phone 5 through the established Bluetooth connection. At the same time, the ...

Embodiment 2

[0043] Such as figure 1 and figure 2 As shown, the low-cost mobile phone and car-machine interconnection system described in the present invention, the car-machine also includes an in-car control system 4 (such as: ECU), and the Bluetooth interconnection module 6 is composed of a Bluetooth sub-module 6c and a wireless charger. The electronic module 6a is composed of, because the power consumption of the mobile phone is relatively large, so the wireless charging sub-module 6a is integrated in the Bluetooth interconnection module 6, and the mobile phone is charged through the wireless charging sub-module 6a. The Bluetooth interconnection module 6 is integrated in the in-vehicle control system 4 . The Bluetooth interconnection module 6 is connected with the in-vehicle control system 4 through a CAN line. When the in-vehicle control system 4 detects the door open signal, it turns on the Bluetooth interconnection module 6 (when the car door is opened, the car door signal light s...

Embodiment 3

[0046] Such as figure 1 and figure 2 As shown, in the low-cost mobile phone and car machine interconnection system described in the present invention, the Bluetooth interconnection module 6 is composed of a Bluetooth sub-module 6c, an NFC sub-module 6b and a wireless charging sub-module 6a, wherein the NFC sub-module 6b passes through the serial port As an independent submodule, the Bluetooth submodule 6c and the wireless charging submodule 6a are integrated with the Bluetooth submodule 6c and the NFC submodule 6b to form the Bluetooth interconnection module 6 . The Bluetooth interconnection module 6 is integrated in the car radio 7 .

[0047] All the other parts are the same as the first embodiment.
