[0004] Currently, vehicle keys are generally divided into physical keys and digital keys. Digital keys typically communicate with the vehicle through Bluetooth technology such as BLE (Bluetooth Low Energy) and UWB (Ultra Wide Band). The digital key's proximity-free unlocking function requires precise positioning of the mobile device and the vehicle. To achieve accurate positioning, the mobile device must be calibrated to eliminate radio frequency differences between different mobile devices and ensure a consistent user experience.

[0005] Taking digital keys in mobile phones as an example, currently, when calibrating digital keys, car manufacturers purchase the top 30-50 mobile phones on the market and manually calibrate each phone separately. This method not only requires purchasing multiple models of mobile phones for calibration, which is costly, but also fails to cover all types of mobile phones. At the same time, manual calibration is inefficient and costly.

[0044] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0045] The digital key's proximity unlocking feature requires precise positioning of the mobile device (such as a phone) and the vehicle. This allows the user to automatically unlock the vehicle by approaching the vehicle (3-6 meters) while holding or wearing the mobile device, start the vehicle from within (1 meter), and lock the vehicle from a distance (6-15 meters). Implementing this solution requires mobile device calibration, which aims to eliminate radio frequency differences between different mobile devices and ensure a consistent user experience.

[0046] At present, when calibrating digital keys, automobile manufacturers purchase top-ranked mobile terminals for manual calibration and manually collect data to calibrate digital keys. For example, as shown in Figure 1, it is a schematic diagram of manually calibrating digital keys. Figure 1 shows three calibration areas, which are located on the left, right and rear sides of the vehicle. Each calibration area contains three semicircular circles for calibrating different functions, and each calibration area contains multiple angles. When manually calibrating a digital key, the calibrator takes the mobile terminal and stands at the intersection of each semicircular circle and the angle line in each calibration area to collect data at the corresponding position. With this calibration method, it takes 3-4 working days to complete the calibration work for one vehicle and one mobile terminal, which is time-consuming, inefficient, and requires labor costs. In addition, there are too many models of user mobile terminals on the market (taking mobile phones as an example, there are many models of user mobile phones on the market), and automobile manufacturers can only cover users of dozens of mobile terminal models. Not only is the cost high but the user coverage rate is low. If all mobile terminals need to be calibrated, all mobile terminal models on the market need to be purchased, which will cost more calibration costs, and the mobile terminal models on the market are constantly updated and iterated.

[0047] To this end, the present application provides a digital key calibration method, apparatus, calibration device and readable storage medium for reducing the cost of digital key calibration and improving the efficiency of digital key calibration.

[0048] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0049] Referring to FIG. 2 , which shows a flow chart of a digital key calibration method provided in an embodiment of the present application, the digital key calibration method provided in an embodiment of the present application is applied to a movable calibration device. The digital key calibration method may include:

[0050] S11: Acquire terminal information of the mobile terminal, generate a virtual terminal corresponding to the mobile terminal according to the terminal information of the mobile terminal, and establish a communication connection between the virtual terminal and the vehicle.

[0051] The digital key calibration method provided in the embodiment of the present application can be applied to a movable calibration device, which can specifically be a robot, or a control device that can control itself to move (for example, the control device can include a mobile platform and a controller placed on the mobile platform, and the controller can communicate with the mobile platform to control the mobile platform to drive the controller to move, etc.). Of course, the movable calibration device can also be in other forms, as long as it can control itself to move.

[0052] Among them, the mobile calibration device can be installed with a cloud real machine, which can provide a large number of virtual mobile terminals, that is, it can simulate a large number of real mobile terminals. It should be noted that the mobile terminal provided in the embodiment of the present application can specifically be a mobile phone, of course, it can also be a mobile terminal with Bluetooth function such as a tablet computer.

[0053] When performing digital key calibration, the portable calibration device first obtains the terminal information of the mobile terminal to be calibrated. The terminal information can specifically include information such as the model name, such as the model of the user's mobile phone. Then, based on the terminal information of the mobile terminal and the cloud-based real device installed on it, a virtual terminal corresponding to the mobile terminal can be generated using the cloud-based real device. In other words, the portable calibration device simulates and generates a virtual, digitized terminal corresponding to the mobile terminal, so as to facilitate digital key calibration based on the virtual terminal corresponding to the mobile terminal. Of course, the portable calibration device can also directly generate a virtual terminal corresponding to the mobile terminal through other methods such as modeling and simulation.

[0054] After generating a virtual terminal corresponding to the mobile terminal based on the terminal information of the mobile terminal, the calibration device can activate the virtual terminal and establish a communication connection between the virtual terminal and the vehicle, allowing the virtual terminal to interact with the vehicle, thereby facilitating data collection and digital key calibration. The aforementioned communication connection method is the same as the communication connection method between the mobile terminal and the vehicle when used as a digital key, such as a Bluetooth connection, so that the virtual terminal can effectively simulate the communication connection method between the digital key and the vehicle, thereby facilitating the accuracy of digital key calibration.

[0055] S12: Collect interaction data between the virtual terminal and the vehicle at multiple target positioning points respectively.

[0056] After establishing a communication connection between the virtual terminal and the vehicle, a mobile calibration device can carry the virtual terminal to each target location and collect interaction data between the virtual terminal and the vehicle at each target location. The target location can be pre-set based on the digital key's usage requirements, and the target location serves as the calibration point for the digital key. The collected interaction data between the virtual terminal and the vehicle specifically refers to the signal strength when the virtual terminal and the vehicle interact via Bluetooth.

[0057] S13: Calibrate the mobile terminal according to the interaction data collected at the multiple target positioning points to obtain calibration parameters corresponding to the mobile terminal.

[0058] After the movable calibration device collects the interaction data between the virtual terminal and the vehicle at the target positioning point, it can calibrate itself using a calibration algorithm based on the interaction data collected at multiple target positioning points to obtain calibration parameters corresponding to the mobile terminal, or it can send the interaction data collected at each target positioning point to the MCU (Microcontroller Unit) in the vehicle, and the MCU calibrates the interaction data collected at each target positioning point using a calibration algorithm to obtain calibration parameters corresponding to the mobile terminal. When sending the interaction data collected at each target positioning point to the MCU in the vehicle, the interaction data collected at each target positioning point can be sent to the MCU in the vehicle after the interaction data is collected at the target positioning point, or the interaction data collected at all target positioning points can be sent to the MCU in the vehicle together after the interaction data is collected at all target positioning points.

[0059] After obtaining the calibration parameters corresponding to the mobile terminal, the calibration parameters corresponding to the mobile terminal can be stored in the vehicle, so that when the corresponding mobile terminal is used as a digital key to control the vehicle later, the vehicle can perform corresponding operations according to the calibration parameters corresponding to the mobile terminal. In addition, the obtained calibration parameters can also be sent to the corresponding mobile terminal, so that the user of the mobile terminal can know that the calibration of the digital key of the mobile terminal has been completed, and the user of the mobile terminal can subsequently use the mobile terminal as the digital key of the vehicle to control the vehicle. Among them, when the calibration parameters are obtained by a movable calibration device, the calibration parameters can be sent to the mobile terminal by the movable calibration device or the vehicle, and when the calibration parameters are obtained by the vehicle, the calibration parameters are sent to the mobile terminal by the vehicle.

[0060] From the above, it can be seen that the embodiment of the present application realizes the automatic calibration of the digital key through the movable calibration device, and does not require manual digital key calibration. Therefore, it can reduce the cost and time of manual calibration, improve the efficiency of digital key calibration, and completely avoid the problem of users not being able to operate the digital key calibration, and improve the user experience. In addition, from the above, it can be seen that the embodiment of the present application can create a virtual terminal corresponding to the mobile terminal in the movable calibration device based on the terminal information of the mobile terminal. It can not only ensure the consistency of user experience while satisfying that all mobile terminal users can use the digital key (that is, it can realize the calibration task of all mobile terminals) to improve user coverage, but also eliminate the need for automobile manufacturers to purchase a large number of different types of mobile terminals, thereby saving the cost of purchasing mobile terminals.

[0061] The above-mentioned technical solution disclosed in the embodiment of the present application obtains the terminal information of the mobile terminal through a movable calibration device, and creates a virtual terminal corresponding to the mobile terminal according to the terminal information and communicates with the vehicle, and then moves the virtual terminal to each target positioning point respectively, collects the interaction data between the virtual terminal and the vehicle at each target positioning point, and calibrates according to the interaction data collected at multiple target positioning points to obtain the calibration parameters corresponding to the mobile terminal. Through the above-mentioned implementation, the calibration of the digital key is automatically completed using the movable calibration device without the need for manual calibration of various mobile terminals, thereby reducing the calibration cost of the digital key, improving the calibration efficiency of the digital key, and improving user coverage.

[0062] In an embodiment of the present application, a digital key calibration method is provided. Target positioning points may include at least a positioning point where a gear can be engaged in a vehicle, a positioning point where the vehicle can be unlocked when approaching the vehicle from the main driver's or co-driver's direction, and a positioning point where the vehicle can be unlocked when approaching the vehicle from the trunk direction. Interaction data between a virtual terminal and the vehicle is collected at each of the target positioning points. The method may include:

[0063] Identify the current relative position of the virtual terminal to the vehicle, determine a first target positioning point based on the current relative position of the virtual terminal to the vehicle, and collect interaction data between the virtual terminal and the vehicle at the first target positioning point;

[0064] After the interaction data between the virtual terminal and the vehicle is collected at the first target positioning point, the second target positioning point is determined, and the interaction data between the virtual terminal and the vehicle is collected at the second target positioning point until the interaction data between the virtual terminal and the vehicle is collected at the last target positioning point.

[0065] In an embodiment of the present application, the movable calibration device uses at least three target positioning points when calibrating the digital key. Specifically, the target positioning points may include at least the following three positioning points: 1. A positioning point that can unlock the vehicle when approaching the vehicle from the main driver's direction or the co-driver's direction, and the positioning point can be at a first preset distance from the main driver or the co-driver; 2. A positioning point that can shift gears in the vehicle, and the positioning point can be in the center of the main driver's window; 3. A positioning point that can unlock the vehicle when approaching the vehicle from the trunk direction, and the positioning point can be at a second preset distance from the trunk of the vehicle. Specifically, please refer to Figure 3, which shows a schematic diagram of the target positioning points included in the digital key calibration method provided by an embodiment of the present application. It should be noted that Figure 3 uses a robot as an example for explanation of the movable calibration device. Among them, the function of point A is that the vehicle can be automatically unlocked when approaching the vehicle from the main driver's direction (wherein, when point A is located at the corresponding position of the co-driver, the function is that the vehicle can be automatically unlocked when approaching the vehicle from the co-driver's direction), the function of point B is to be able to shift gears inside the vehicle, and the function of point C is to automatically unlock the vehicle when approaching the vehicle from the trunk direction. Point A can be located at a first preset distance (e.g., 6 meters) from the main driver's side or a first preset distance from the co-driver's side, point B can be located at the center of the main driver's side window, and point C can be located at a second preset distance (e.g., 6 meters) from the vehicle trunk. Points A and C can achieve approach unlocking and distance locking, and point B can achieve vehicle start. Of course, other target positioning points can also be set according to the functional requirements of the digital key.

[0066] The movable calibration equipment is moved to each target positioning point respectively. The specific process of collecting the interaction data between the virtual terminal and the vehicle at each target positioning point can be as follows:

[0067] (1) Identify the current relative position of the movable calibration device (specifically, the virtual terminal therein) and the vehicle, such as the orientation of the movable calibration device with respect to the vehicle (e.g., the main driving direction, the co-driver direction, the trunk direction, etc.) and the current distance from the vehicle, so as to determine the first target positioning point of the target positioning hour based on the current relative position with respect to the vehicle and plan a path to the first target positioning point. Then, the movable calibration device moves to the first target positioning point and collects interaction data between the virtual terminal and the vehicle at the first target positioning point.

[0068] (2) After the interaction data between the virtual terminal and the vehicle is collected at the first target positioning point, the movable calibration device can determine the second target positioning point from the remaining target positioning points and plan a path to the second target positioning point based on its current relative position with the vehicle. Then, the movable calibration device can move to the second target positioning point and collect the interaction data between the virtual terminal and the vehicle at the second target positioning point... until it moves to the last target positioning point and collects the interaction data between the virtual terminal and the vehicle at the last target positioning point.

[0069] This allows accurate movement to each target location based on the vehicle's current relative position, thereby improving the accuracy of interactive data collection and, in turn, the accuracy of digital key calibration. Furthermore, as can be seen from the above, this embodiment of the present application can streamline the calibration points for digital key calibration, further saving calibration time and improving calibration efficiency.

[0070] An embodiment of the present application provides a digital key calibration method, which collects interaction data between a virtual terminal and a vehicle at a target location, and may include:

[0071] Collect interaction data of a preset duration at the target positioning point.

[0072] When the movable calibration device collects the interaction data between the virtual terminal and the vehicle at each target positioning point, it can collect the interaction data of a preset time length at each target positioning point respectively, wherein the preset time length can be determined in advance by experiment or based on experience, for example, it can be 10s.

[0073] By collecting interaction data for a preset time period at a target positioning point, it is convenient to improve the accuracy of interaction data collection, thereby improving the accuracy of digital key calibration.

[0074] A digital key calibration method provided in an embodiment of the present application may further include, after collecting interaction data of a preset duration at a target positioning point, the following steps:

[0075] Determine whether the collection has failed or whether the collected interaction data is abnormal;

[0076] If the collection fails or the collected interaction data is abnormal, the process returns to the step of collecting interaction data for a preset time period at the target positioning point until the interaction data collection succeeds and the collected interaction data is normal.

[0077] In an embodiment of the present application, after a movable calibration device collects interaction data for a preset time period at a target positioning point, it can determine whether the interaction data collection has failed or whether the collected interaction data is abnormal. A collection failure may mean that no interaction data was collected, and an abnormal interaction data may mean that interaction data was collected but the collected interaction data was abnormal. For example, normal interaction data for each target positioning point can be preset, and the interaction data collected at the corresponding target positioning point can be compared with the normal interaction data to determine whether the collected interaction data is abnormal.

[0078] If the interaction data collection has not failed and the collected interaction data is not abnormal, the next target location can be determined, and the interaction data between the virtual terminal and the vehicle can be collected at the next target location. If the interaction data collection fails or the collected interaction data is abnormal, the interaction data collection can continue at the current target location, that is, the step of collecting interaction data for a preset time period at the target location can be returned to execute until the interaction data is successfully collected at the target location and the collected interaction data is not abnormal. Then, the next target location can be determined, and the interaction data between the virtual terminal and the vehicle can be collected at the next target location.

[0079] The above judgment can improve the quality and accuracy of the collected interaction data, thereby improving the accuracy of data key calibration.

[0080] An embodiment of the present application provides a digital key calibration method for identifying the current relative position of the key to the vehicle, which may include:

[0081] Use infrared radar to identify the current relative position of the vehicle.

[0082] In an embodiment of the present application, an infrared radar may be provided on the movable calibration device, which may be used to identify the current relative position of the movable calibration device and the vehicle, so that the movable calibration device library may be moved to the corresponding target positioning point based on the current relative position with the vehicle.

[0083] Of course, other types of radars or other methods may also be used to identify the current relative position to the vehicle.

[0084] A digital key calibration method provided in an embodiment of the present application may further include:

[0085] Receive login information and verify the login information;

[0086] If the login information is verified, the step of establishing a communication connection between the virtual terminal and the vehicle is executed.

[0087] Before establishing a communication connection between the virtual terminal and the vehicle, the portable calibration device may also receive login information sent by the user of the mobile terminal, which may specifically include a user account number and password. The portable calibration device may include a human-computer interaction interface, through which the user may enter the login information, or by voice.

[0088] The mobile calibration device can then verify the login information, for example by querying the vehicle's cloud platform to see if the login information is stored. If the received login information fails verification, it indicates that the user is not a legitimate user. In this case, the step of establishing a communication connection between the virtual terminal and the vehicle can be rejected, and digital key calibration of the corresponding user's mobile terminal can be rejected. If the received login information passes verification, it indicates that the user is a legitimate user. In this case, the step of establishing a communication connection between the virtual terminal and the vehicle can be executed to perform digital key calibration on the corresponding user's mobile terminal.

[0089] The above process can ensure the reliability and accuracy of the vehicle's digital key verification, thereby reducing property losses.

[0090] An embodiment of the present application provides a digital key calibration method for obtaining terminal information of a mobile terminal, which may include:

[0091] Receive the model information of the mobile terminal input from the outside.

[0092] The movable calibration device can specifically include a human-computer interaction interface, and the outside world (specifically, the user of the mobile terminal, or other personnel who can obtain the model information of the mobile terminal, etc.) can input the model information of the mobile terminal on the human-computer interaction interface, so that the movable calibration device can obtain the terminal information of the mobile terminal conveniently, efficiently and accurately.

[0093] Specifically, the movable calibration device can display the model information of various mobile terminals on the human-computer interaction interface, so that the outside world can select the model information of the mobile terminal to be calibrated on the human-computer interaction interface, or the model information of the mobile terminal to be calibrated can be directly input on the human-computer interaction interface through keyboard input, touch screen input or voice input.

[0094] In order to more clearly illustrate the above technical solution of the present application, it can be specifically described in conjunction with FIG3 and the following embodiment. The following is an example in which the movable calibration device is a robot and the mobile terminal is a mobile phone:

[0095] 1. First, the robot installs the cloud real phone service. The user selects their phone model on the robot interface. The robot activates the virtual phone, verifies the user account, and connects to the vehicle via Bluetooth.

[0096] 2. The robot uses infrared radar to identify the distance to the vehicle, sets a location point A 6 meters from the driver's seat, and collects data at location point A for 10 seconds. If the collected data is abnormal or fails, the robot will determine and re-collect data.

[0097] 3. The robot uses infrared radar to identify the distance to the vehicle, moves forward to a location B in the center of the main driver's window, and collects data at location B for 10 seconds. If the collected data is abnormal or fails, the robot will determine and re-collect data.

[0098] 4. The robot returns to point A and moves to point C, 6 meters from the vehicle's trunk, where it collects data for 10 seconds. If the collected data is abnormal or fails, the robot determines the error and re-collects data.

[0099] 5. After all the data is collected successfully, the vehicle temporarily stores the calibration data. At this time, the robot prompts the user to connect the vehicle with his or her mobile phone. The vehicle transmits the calibration parameters to the user's mobile phone via Bluetooth, thus completing the calibration of the user's mobile phone.
