Problems solved by technology

[0002] At present, the more popular mobile network car control is to remotely control the wireless distance vehicle through the mobile phone network, but there is a problem that the mobile phone network cannot be used to control the car when the mobile phone has no GPRS signal or the original car has no network signal.
Bluetooth car control is to use the mobile phone car control APP to connect to the Bluetooth of the equipment equipped in the car to control the car at a short distance; but there are also situations where the mobile phone must be held in the hand to open the APP before it can be used, and there will be cases when the mobile phone has no GPRS signal or the battery power of the mobile phone When it is insufficient, the APP cannot be opened to connect to the Bluetooth device, and the function is inconvenient to use and the function cannot be used, which brings great trouble to the user.

Embodiment 1

[0028] refer to figure 2 , in this embodiment, the Bluetooth module receives the control command and forwards it to the vehicle body controller.

[0029] The vehicle control system described in this embodiment can wirelessly control the original vehicle through the mobile terminal APP to unlock, lock, search for, open the trunk, close the trunk, search for the car, start and / or turn off the engine.

Embodiment 2

[0031] refer to image 3 As shown, the Bluetooth module establishes HID communication with the mobile terminal, the Bluetooth module obtains the signal strength or distance between it and the mobile terminal, and when the signal strength or distance reaches the preset condition, the vehicle-mounted terminal Send unlock or lock command to body controller.

[0032] In this embodiment, the Bluetooth module is equipped with a HID protocol. After the Bluetooth module establishes Bluetooth pairing with the mobile terminal APP and passes the verification, the Bluetooth module communicates with the mobile terminal APP through the HID protocol. System Bluetooth establishes a Bluetooth connection.

[0033] When the signal strength or distance reaches the preset condition, the specific meaning of the vehicle-mounted terminal sending an unlock or lock command to the body controller is as follows:

[0034] The Bluetooth module obtains the signal strength or distance between it and the mo...

Embodiment 3

[0038] After the Bluetooth module establishes Bluetooth pairing with the mobile terminal APP and passes the verification, the user operates the mobile terminal APP point to generate an NFC key, and brings the NFC device close to the mobile terminal APP, and the mobile terminal APP passes the NFC key generation module Read the UID of the NFC device, and then authenticate and store the read UID in the NFC module and the cloud server.

[0039] refer to Figure 4 As shown, in this embodiment, the NFC device with the above-mentioned UID is brought close to the NFC module, and the vehicle-mounted terminal sends an unlock or lock command to the vehicle body controller.

[0040] In this embodiment, the vehicle-mounted terminal is installed on the inside of the vehicle window, and when the original vehicle is in the locked state, after the NFC device with the above-mentioned UID is brought close to the vehicle-mounted terminal, an unlock command is sent to the vehicle body controller, ...
