For a better understanding of the present invention, first, the meaning of smart key calibration will be briefly described: the Bluetooth digital key can realize keyless entry and one-key starting, in order to ensure safety, a vehicle-mounted communication module comprehensively judges whether the distance between a mobile terminal (a mobile phone or wearing equipment and the like) and a vehicle is in an effective range or not through a sensor (generally, the keyless entry is 3 meters, the deviation in one-key starting vehicle is not more than 1 meter), and in order to ensure the positioning of the vehicle to the mobile terminal aiming at the difference of different mobile terminals, the mobile terminal needs to be calibrated before use, and the RSSI data of the mobile terminal in different positions inside and outside the vehicle needs to be acquired in the calibration process as reference data.
As shown in fig. 1, a main flow diagram of an embodiment of a smart key calibration data synchronization method provided by the present invention is shown, and in combination with fig. 2, in this embodiment, the method includes the following steps:

table 1 calibration data base data example (version number: v 1.0)
It can be appreciated that smart key calibration data of each model of mobile terminal corresponding to each vehicle model needs to be stored in the calibration database in advance. The present invention therefore needs to include the following steps: the intelligent key calibration data of each model of mobile terminal corresponding to each vehicle type are obtained in advance through a manual calibration mode and stored in the calibration database. The method comprises the steps that a host factory engineer manually calibrates according to the model of a mobile terminal (such as a mobile phone) which is continuously updated in the market to form a calibration database, and the calibration database is periodically updated according to the flow of the host factory according to the mapping relation between the model, different mobile phone brands and different mobile phone models (wearable equipment models).
Step S11, after inquiring that the calibration data of the current mobile terminal model corresponding to the current vehicle model is updated, downloading the updated calibration data and covering the stored calibration data on the mobile terminal;
step S12, after the calibration database cannot be connected or the calibration data of the current mobile terminal model corresponding to the current vehicle model is inquired to be not updated, the stored calibration data in the mobile terminal are used; or the calibration data of the current mobile terminal corresponding to the current vehicle type is obtained and stored in a manual calibration mode;

The step S13 further includes: and in a second preset time (such as 60 seconds) after the vehicle-mounted communication module establishes communication connection with the mobile terminal, if the vehicle-mounted communication module does not receive the calibration data from the mobile terminal, feeding back a message of 'calibration data error' to the mobile terminal.
It is understood that in the present invention, the near field communication connection may be, for example, a bluetooth connection, an NFC (Near Field Communication ) connection, an UWB (Ultra wide band) connection, or the like.
It can be understood that the vehicle-mounted communication module can determine whether the mobile terminal is outside or inside the vehicle according to the current RSSI value and calibration data of the mobile terminal; in the case of off-board, what is the distance from the vehicle, etc. The matters not focusing on the present invention are not described in detail here.
It will be appreciated that when the vehicle communication module determines the exact location of the mobile terminal, it may send the location information to a keyless entry and start system (PEPS) for subsequent operations (e.g., opening a door, starting a car, etc.).
More specifically, the step S12 specifically includes:
step S120, the mobile terminal prompts a user to place the mobile terminal in a designated area, and a calibration mode is started in response to user operation; the specified area is a range of distances of 1 meter from the left front door handle of the vehicle outside the vehicle.
Step S121, the mobile terminal establishes near field communication connection with the vehicle-mounted communication module, and notifies the vehicle-mounted communication module to work in a calibration mode and broadcasts a message;
in step S122, the mobile terminal receives calibration data from the vehicle-mounted communication module, where the calibration data is obtained by the vehicle-mounted communication module according to RSSI information of the mobile terminal received by a plurality of connected sensors disposed at different positions on the vehicle body in a calibration mode. In one example, the vehicle-mounted communication module is arranged on a vehicle center console, and a plurality of sensors connected with the vehicle-mounted communication module through a private bus are respectively arranged at least two positions of the left side, the right side, the rear floor and the rear bumper of the vehicle. More specifically, in one example, the calibration data may be RSSI signal values of the handsets detected by the respective sensors.
In one example, the step S12 further includes:
and in a first preset time (for example, 30 seconds) after the near field communication connection between the mobile terminal and the vehicle-mounted communication module is established, if the mobile terminal does not receive the calibration data from the vehicle-mounted communication module, prompting that the manual calibration process fails. In some examples, a manual calibration failure may occur if there are situations, for example, during calibration, the mobile terminal is located in a car; during calibration, the vehicle-mounted communication module has no data; calibrating on the right side outside the vehicle; performing operations at a greater distance than 1 meter; or left front door not closed, etc.
It can be understood that in the embodiment of the invention, the latest calibration data is stored in the calibration database, and the corresponding calibration data of the intelligent key is stored in the mobile terminal, when the mobile terminal is connected with the vehicle, whether the calibration data is updated or not can be queried in real time, and the latest calibration data is obtained from the calibration database and transmitted to the vehicle-mounted communication terminal so as to realize the function of the intelligent key; according to the method, calibration data are not required to be stored in the vehicle-mounted Bluetooth end all the time, the real-time performance and the efficiency of data synchronization are improved, the cost of calibration data synchronization is reduced, and good user experience and flexibility can be brought.
