The embodiment of the invention provides a digital key calibration method.
Referring to fig. 2, fig. 2 is a schematic flow chart of a digital key calibration method according to a first embodiment of the present invention; in the first embodiment of the invention, the digital key calibration method is applied to a mobile terminal, and the mobile terminal is connected with a cloud server; the method comprises the following steps:
step S10, receiving user calibration parameters input by a user, and sending the user calibration parameters to the cloud server;
in this embodiment, the mobile terminal may be an intelligent terminal having a near field communication function, such as a mobile phone, a tablet computer, an intelligent watch, and an intelligent bracelet.
The user calibration parameters are user-defined calibration parameters including, but not limited to, a target gear, a mobile phone model, a vehicle model, and a vehicle identification code. And the mobile phone model, the vehicle model and the vehicle identification code can be directly read by digital key software after the mobile terminal and the vehicle are connected by Bluetooth without being manually input by a user. The target gear can include 0 gear, +1 gear, +2 gear, +3 gear, -1 gear, -2 gear and-3 gear, and the gear means: the positive gears of +1 gear, +2 gear and +3 gear are positive compensation for the intensity parameter of the bluetooth signal on the basis of 0 gear, and are used for mobile terminals with weaker intensity of the bluetooth signal. The negative gears of-1 gear, -2 gear and-3 gear are negative compensation of the Bluetooth signal strength parameter on the basis of 0 gear, and are used for mobile terminals with over-strong Bluetooth signals.
The user can calibrate the digital key parameters in a digital key software mode, and can output preset standard suggestion prompts while receiving the user calibration parameters input by the user, for example, the standard suggestion prompts can be 'suggestion setting is close to 3 meters for unlocking and 8 meters for locking', so as to assist the user to better set the calibration parameters according to actual needs, wherein the mode of outputting the preset standard suggestion prompts is not limited to a popup window display mode, a user interface display mode of the user calibration parameters of the digital key software, a voice prompt mode and the like. After user calibration parameters input by a user are received, when a digital key generation instruction of the user is received, the user calibration parameters and the digital key generation instruction are sent to a cloud server of the mobile terminal, a user of the cloud server automatically generates a corresponding digital key according to the user calibration parameters, the cloud server can further comprise various calibration parameters for calibrating the intelligent terminal, and when the mobile terminal of the user is judged to be the calibrated intelligent terminal, the digital key can be directly generated according to the mobile terminal model and the calibration parameters corresponding to the mobile terminal model and sent to the mobile terminal.
In an embodiment, before the step S10, the method further includes:
step a, detecting whether a target calibration parameter corresponding to the terminal model of the mobile terminal exists in the cloud server;
b, if the target calibration parameters do not exist in the cloud server, acquiring preset calibration parameters in the cloud server and displaying the preset calibration parameters;
and c, executing the step of receiving the user calibration parameters input by the user based on the preset calibration parameters.
When user calibration parameters input by a user are allowed and received, a terminal model of the mobile terminal can be obtained first, a terminal model and a digital key request instruction are sent to the cloud server, the cloud server feeds back a corresponding request result according to the terminal model and the digital key request instruction to detect whether a target calibration parameter corresponding to the terminal model of the mobile terminal exists in the cloud server according to the request result, if the target calibration parameter corresponding to the terminal model does not exist in the cloud server, namely the mobile terminal of the user belongs to a non-calibrated mobile terminal, in order to enable the user to set the user calibration parameters more conveniently, the preset calibration parameters in the cloud server can be further obtained and displayed to the user, and the user can set the user calibration parameters on the basis of the preset calibration parameters. The preset calibration parameters may include an average gear or a median gear of a terminal series corresponding to the terminal model, for example, the P40 series includes a plurality of specific terminal models, the bluetooth signal strength of each terminal model has a certain difference, and an average value of the gears calibrated to the P40 series in the cloud server may be taken as the preset calibration parameters corresponding to the terminal model of the user, so that the preset calibration parameters may be matched with or have a smaller difference from the actual bluetooth signal strength of the mobile terminal of the user to a great extent, and the user may obtain a digital key satisfying the user and having a normal function by simply adjusting the preset calibration parameters or without adjusting the preset calibration parameters.
Step S20, receiving a digital key fed back by the cloud server based on the user calibration parameter;
after the cloud server receives the user calibration parameters and the digital key generation instruction, association and authentication can be performed on all the parameters in the user calibration parameters, so that the digital key corresponding to the user calibration parameters is generated and issued to the mobile terminal, and the mobile terminal receives the digital key.
And step S30, determining a vehicle corresponding to the digital key, and sending the digital key to the vehicle.
When the mobile terminal is not in Bluetooth connection with the vehicle, the user vehicle corresponding to the digital key needs to be found and determined first, and then the digital key is synchronized into a Bluetooth module of the vehicle through Bluetooth transmission. The digital key may also be sent directly to the vehicle if the mobile terminal has previously made a bluetooth connection with the vehicle. In one embodiment, if the vehicle is in a networking state, the digital key can be synchronously sent to the mobile terminal and the vehicle through the cloud server.
In an embodiment, the step S30 includes:
d, acquiring all Bluetooth signals in a preset range, and filtering off-vehicle Bluetooth signals in the Bluetooth signals to obtain vehicle-mounted Bluetooth signals;
step e, determining a target Bluetooth signal which is consistent with the Bluetooth address in the digital key in the vehicle-mounted Bluetooth signal, and determining a vehicle corresponding to the target Bluetooth signal;
and f, connecting the vehicle through Bluetooth and sending the digital key to the vehicle.
In this embodiment, the preset range can be set according to actual needs, for example, 10m, but cannot exceed 30m, because 30m is the limit distance of the current civilian bluetooth, and vehicles exceeding 30m of the mobile terminal cannot be detected naturally. Detect in order to acquire all bluetooth signal of predetermined range, non-on-vehicle signal in the bluetooth signal carries out the filtering shielding, thereby just can confirm all on-vehicle bluetooth signal of predetermined range this moment, wherein the mode of filtering non-on-vehicle bluetooth signal can go on through the mode of bluetooth name, general on-vehicle bluetooth's name is distinguished from other non-on-vehicle bluetooth, other non-this brand bluetooth signal can also be selected to filter in all bluetooth signal by the car company in order to obtain on-vehicle bluetooth signal in addition, can be through this brand specific bluetooth name with the bluetooth signal differentiation as non-on-vehicle bluetooth signal and on-vehicle bluetooth signal promptly. The Bluetooth signal quantity can be reduced through the mode of filtering the Bluetooth signals so as to rapidly position the Bluetooth signals of the target vehicle of the user, and then the residual vehicle-mounted Bluetooth signals carry out Bluetooth connection on the target vehicle of the user through the Bluetooth address in the digital key, and the digital key is sent to the target vehicle of the user when the Bluetooth connection is completed.
Referring to fig. 3, in an embodiment, after the step S30, the method further includes:
step S40, when the prompt information that the vehicle is unlocked by the Bluetooth or locked by the Bluetooth is received, receiving a distance adjusting instruction of a user;
and S50, updating the digital key according to the distance adjusting instruction and sending the updated digital key to the vehicle.
Since the user often performs the actual distance of on-site test unlocking and locking after setting the user calibration parameters to obtain the digital key, taking bluetooth unlocking as an example, when the user performs the test of bluetooth unlocking, the vehicle can be unlocked when the user approaches the vehicle for a certain distance, and simultaneously the prompt message of bluetooth unlocking is sent to the mobile terminal, when the mobile terminal receives the prompt message of bluetooth unlocking, the user can decide not to increase or decrease the unlocking distance according to the prompt and the position where the user is located, assuming that the distance between the user and the vehicle is 5m, the vehicle performs bluetooth unlocking, the user feels that the distance is long and worried that the distance is not safe enough, the unlocking distance can be adjusted through the mobile terminal, that is, the mobile terminal receives the distance adjustment instruction of the user, for example, the user can input the distance adjustment instruction of 2m reduction, the mobile terminal can determine a gear to be shifted according to the distance adjusting instruction and the gear of the current digital key, for example, the gear of the current digital key is a-1 gear, the mobile terminal of a user can be determined to belong to the mobile terminal with the too strong Bluetooth signal intensity, the gear of the digital key needs to be reduced according to the distance adjusting instruction reduced by 2m, the reduction amount can be determined according to the current gear and the specific distance adjusting instruction, for example, the gear of the current digital key is the-1 gear, the distance adjusting instruction is reduced by 2m, the gear to be shifted can be set to the-2 gear, the-2 gear parameter is sent to the cloud server to update the current digital key, and the digital key of the vehicle needs to be updated synchronously to ensure that the key of the mobile terminal and the vehicle is matched when the digital key is updated. The adjustment of other functions of the digital key such as bluetooth lock is the same as above, and will not be described in detail herein.
Through the embodiment, the perception of the user can be combined, the user can conveniently and accurately adjust the digital key, the adjustment times of the user on the digital key are reduced, and the use experience of the user on the digital key is improved.
The invention meets the use requirements of users on various functions of the digital key to the maximum extent mainly by giving users a mode of self-defining calibration parameters aiming at non-calibrated intelligent terminals to generate the digital key, accords with the use habits of the users, is more humanized, and greatly relieves the working pressure and cost of vehicle enterprises for calibrating the digital key of various intelligent terminal models.
Referring to fig. 4, fig. 4 is a schematic flow chart of a digital key calibration method according to a second embodiment of the present invention; further, a second embodiment of the digital key calibration method of the present invention is proposed based on the first embodiment of the digital key calibration method of the present invention, and in this embodiment, after the step S30, the method further includes:
step S31, acquiring a real-time distance between the mobile terminal and the vehicle, and determining user behaviors according to the real-time distance;
in this embodiment, the real-time distance between the mobile terminal and the vehicle may be detected by the vehicle and sent to the mobile terminal, or the real-time distance between the mobile terminal and the vehicle may be detected by the mobile terminal, where the difference between the real-time distance and the real-time distance is that which main body receives the broadcast bluetooth signal of another main body to determine the bluetooth signal strength of the other main body.
The real-time distance between the mobile terminal and the vehicle is acquired in real time, the behavior of the user can be determined to be whether the user walks into the vehicle or leaves the vehicle by acquiring the real-time distance in real time and further determining the change trend of the real-time distance, the vehicle which walks into the vehicle can be determined as that the user intends to unlock the vehicle for use, and the vehicle which leaves the vehicle can be determined as that the user leaves the locked vehicle.
Step S32, if the user behavior belongs to an approaching vehicle behavior, judging whether a main driving distance in the real-time distance reaches an unlocking distance corresponding to the digital key;
and S33, if the main driving distance reaches the unlocking distance corresponding to the digital key, sending an unlocking instruction to the vehicle to unlock the vehicle.
Due to the fact that the size of the vehicle body is large, in order to refine the unlocking distance of a user, the real-time distance can include the main driving distance and the auxiliary driving distance under the condition that the left vehicle door and the right vehicle door of the vehicle are respectively provided with the left Bluetooth module and the right Bluetooth module, and then the main driving distance in the real-time distance, namely the distance from the mobile terminal to the main driving door, can be determined.
If the user behavior belongs to a walking vehicle, namely the user intends to unlock the vehicle, judging whether the main driving distance reaches the unlocking distance in the digital key, and unlocking the vehicle door only when the main driving distance reaches the unlocking distance, wherein the unlocking of the vehicle door can be realized by actively unlocking the vehicle according to the Bluetooth signal intensity of the mobile terminal, or by sending an unlocking instruction to the vehicle by the mobile terminal when the unlocking distance is judged to be reached so as to unlock the vehicle.
Through this embodiment, can realize becoming more meticulous the unblock, further promote the user and use the experience of using the digital key.

and h, if the actual unlocking distance or the actual locking distance does not accord with the respective corresponding preset standard distance range, outputting corresponding prompt information to remind a user to reset the user calibration parameter.
In this embodiment, it is considered that the distance is reliably and accurately determined based on the intensity of the bluetooth signal broadcast by the bluetooth module of the vehicle, considering that the intensity of the bluetooth signal broadcast by the bluetooth module of the vehicle is almost not different for each mobile terminal despite the difference in the intensity of the bluetooth signal of the mobile terminal. Then, the actual unlocking distance or the actual locking distance between the mobile terminal and the vehicle can be determined according to the bluetooth signal strength broadcasted by the vehicle, that is, the actual distance between the corresponding mobile terminal and the vehicle when the vehicle is unlocked and the actual distance between the corresponding mobile terminal and the vehicle when the vehicle is locked are determined, whether the actual unlocking distance or the actual locking distance meets the respective corresponding preset standard distance range or not is respectively determined, if the actual unlocking distance does not meet the corresponding preset standard distance range, the user can be prompted to reset the user calibration parameter to adjust the unlocking distance, and if the actual locking distance does not meet the corresponding preset standard distance range, the user can be prompted to reset the user calibration parameter to adjust the unlocking distance, wherein the preset standard distance range can be a standard distance range suggested by the vehicle enterprises or a standard distance range expected and set by the user.
Through the embodiment, the user can be helped to adjust the calibration parameters at the reasonable or expected unlocking distance or locking distance, so that the generated digital key can actually meet the use requirements of the user to the maximum extent.
