Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a method, device and system for adjusting calibration data of a vehicle digital key. Background Art

[0002] The core function of the digital key for cars is to realize the positioning of the mobile phone by the Bluetooth antenna on the car side. The current positioning performance of the digital key for cars depends on the positioning algorithm and calibration parameters. The calibration parameters specify the field strength values ​​of unlocking and locking and related specific areas. The algorithm locates different areas according to the characteristic values ​​in the calibration parameters.

[0003] However, generally speaking, algorithms are difficult to upgrade. There are two types of calibration parameters: official calibration and self-calibration. Official calibration is performed by vehicle manufacturers on certain mobile phones with large usage. Calibration data for each mobile phone model is generated based on the field strength characteristics of different mobile phones and uploaded to the cloud. During user use, the calibration data of the corresponding mobile phone model will be pulled from the cloud to achieve positioning; self-calibration relies on the user to collect the signals of each antenna at a relative position to generate self-calibration data and upload it to the cloud as the exclusive calibration data under the user account, which is used for the calibration parameters of vehicle-side positioning.

[0004] Since the digital key for the car uses the Bluetooth field strength for positioning, due to the natural physical characteristics of the Bluetooth protocol and band, whether it is official calibration or self-calibration, there will be deviations between the actual usage scenario effect and the actual calibration status. The main difference is that different mobile phones of the same mobile phone model will have perceptible differences in unlocking distance and stability on the same vehicle. The vehicle manufacturer can only regulate the consistency of the Bluetooth module on the vehicle side and cannot require it, and cannot restrict the mobile phone, resulting in slight differences between the actual use results and the expected functional status. For self-calibration users, many times they cannot calibrate completely according to the requirements and instructions on the mobile phone, resulting in problems with the self-calibration data. This will also cause differences between the actual use results and the expected functional status, resulting in a poor user experience. Summary of the invention

[0062] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0063] The following describes the method, device, electronic device and storage medium for adjusting the calibration data of a digital key for a vehicle according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0064] Figure 1 A flow chart of a method for adjusting the calibration data of a vehicle digital key provided by an embodiment of the present disclosure. The method is applied to a server, such as Figure 1 As shown, the method comprises the following steps:

[0065] Step 101: Identify the locking anomaly according to the log data sent by the target vehicle and determine the anomaly category of the locking anomaly.

[0066] In actual applications, the scenarios that affect the user's car experience are mostly when the user approaches the vehicle with a Bluetooth key to unlock it, but the vehicle triggers the lock when the user moves away from the vehicle without opening the door, opening the tailgate, or pulling out the charging gun. The lock anomaly can be divided into lock anomaly and charging anomaly. In the embodiment of the present application, the server identifies the lock anomaly based on the log data (such as the cloud CAN log) sent by the target vehicle.

[0067] Step 102: According to the correspondence between the abnormal category and the delay zone adjustment rule, determine the target delay zone adjustment rule corresponding to the abnormal category.

[0068] In the embodiment of the present application, when the digital key leaves the delay circle area, the timing starts, and when the time of leaving the delay circle reaches the preset locking time (such as 6 seconds), the target vehicle is locked. The preset locking time is an empirical value, which can also be set to 10 seconds, 12 seconds, etc., and the specific embodiment of the present application is not limited.

[0069] In a target vehicle, corresponding delay circles can be set for different doors, that is, if the target vehicle has 4 doors, 4 different delay circles can be set; or, a delay circle can be set for the target vehicle as a whole. The embodiment of the present application does not limit the number of delay circles. It should be noted that no matter how many delay circles there are, the functions and usage principles of different delay circles are the same.

[0070] The correspondence between the abnormal categories and the delay circle area adjustment rules is pre-configured, and different abnormal categories appear in different scenarios where the delay circle is too large or too small.

[0071] Step 103: adjusting the calibration data corresponding to the delay circle area according to the delay circle area adjustment rule.

[0072] The correspondence between the abnormal category and the delay zone adjustment rule is configured in advance. The delay zone adjustment rule is configured to adjust the calibration data corresponding to the delay zone according to the abnormal category, that is, to increase or decrease the processing.

[0073] The present embodiment provides a method for adjusting the calibration data of a digital key for a vehicle, which identifies the locking anomaly based on the log data sent by the target vehicle, determines the abnormal category of the locking anomaly, determines the target delay circle area adjustment rule corresponding to the abnormal category based on the correspondence between the abnormal category and the delay circle area adjustment rule, and adjusts the calibration data corresponding to the delay circle area based on the delay circle area adjustment rule. Compared with the existing related technologies, first, the cloud server determines the abnormal category of the locking anomaly based on the log data, and dynamically adjusts the target delay circle area corresponding to the abnormal category according to the abnormal category, thereby eliminating the difference between the actual use result of the digital key for the vehicle and the expected functional status.

[0074] In the embodiment of the present application, due to the consistency deviation between the vehicle usage environment and the mobile phone antenna, the official standard vehicle digital key calibration data may use the cloud CAN log to identify the abnormal scenarios in certain abnormal scenarios, and iterate and optimize the self-calibration data according to the characteristics of multiple abnormal scenarios.

[0075] As a refinement of the above embodiment, when the step 101 of identifying the locking abnormality according to the log data sent by the target vehicle and determining the abnormality category of the locking abnormality is performed, it can be implemented in but not limited to the following manner: the locking signal and / or unlocking signal and the charging status in the log data are analyzed to determine the abnormality category of the locking abnormality; when it is determined that the locking signal is triggered and the unlocking signal is triggered within a first preset time period, the abnormality category is determined to be a bypassing vehicle category; when it is determined that the charging port cover state is open, and the locking signal is triggered, and the unlocking signal is triggered within a second preset time period, the abnormality category of the locking abnormality is determined to be a charging category.

[0076] Scenario 1: After the target vehicle is connected to Bluetooth, the relevant vehicle-side signal collects that Bluetooth is connected, and the Bluetooth connection triggers the vehicle approach unlocking within N seconds (N represents any time). After the approach unlocking is triggered, the door is not opened, which triggers the vehicle to lock. Within the first time period after locking (such as within 6 seconds), the approach to the target vehicle is triggered to unlock, or the touch unlock is triggered.

[0077] Scenario 2: After the target vehicle is connected to Bluetooth, the relevant vehicle-side signal collects that Bluetooth is connected, and the charging cover is in the open state: the vehicle approach unlock is triggered within the second time period of Bluetooth connection (such as within 12s), and the door is not opened after the approach unlock is triggered, triggering the vehicle to lock: Bluetooth key is valid || vehicle lock (|| is or), and the approach unlock is triggered within M seconds after locking (M represents any time), or touch unlock, or press the charging cover.

[0078] Scenario 3: Disconnected locking scenario: Disconnected locking, locking; the delay circle needs to be less than the unlocking value of the four-door keyless entry system (Passive Entry, PE) during the iterative update and amplification process.

[0079] The signals of the above scenarios 1, 2 and 3 will all be recorded in the log data. Based on the locking signal / unlocking signal in the log data, the server analyzes the locking signal and / or unlocking signal and the charging status in the log file.

[0080] Exemplarily, when it is determined that the locking signal is triggered, that is, the vehicle digital key leaves the delay circle area, the timing starts. When the time of leaving the delay circle reaches the preset vehicle locking time (such as 6 seconds), the target vehicle is locked and the locking signal is triggered. After locking, the unlocking signal is triggered within the first preset time period (such as 6 seconds), indicating that the vehicle has not entered the delay circle area, and the abnormality category is determined to be the circumvention category, which corresponds to the above-mentioned scenario one.

[0081] If it is determined that the abnormal category is the vehicle bypass category, then it is determined that the target delay circle area is relatively small. According to the correspondence between the abnormal category and the delay circle area adjustment rule, the target delay circle area adjustment rule is determined to be to increase the calibration data corresponding to the target delay circle area, and the calibration data corresponding to the delay circle area is increased on the cloud server.

[0082] Exemplarily, when it is determined that the charging port cover is open and the locking signal is triggered, that is, the vehicle digital key leaves the delay circle area, the timing starts. When the time left the delay circle reaches the preset vehicle locking time (such as 6 seconds), the target vehicle is locked, and the unlocking signal is triggered within a second preset time period (such as 12 seconds), indicating that the delay circle area has not been entered. The abnormality category of the locking abnormality is determined to be the charging category, corresponding to the above-mentioned scenario two.

[0083] If it is determined that the abnormal category is the charging category, then it is determined that the target delay circle area is relatively large. According to the correspondence between the abnormal category and the delay circle area adjustment rule, the target delay circle area adjustment rule is determined to reduce the calibration data corresponding to the target delay circle area, and the calibration data corresponding to the delay circle area is reduced.

[0084] As a feasible method of an embodiment of the present application, the adjustment of the calibration data corresponding to the delay circle area according to the standard delay circle area adjustment rule includes: adjusting the antenna field strength value corresponding to the calibration data according to the standard delay circle area adjustment rule. When adjusting the antenna field strength value, it can be increased or decreased in a step-by-step manner, for example, the step amplitude is +1 or -1, +2 or -2, etc. The specific embodiment of the present application does not limit the adjustment amplitude of the field strength value.

[0085] In order to achieve consistency between the vehicle digital key calibration data of the cloud server and the vehicle-side data, after adjusting the calibration data corresponding to the delay circle area according to the delay circle area adjustment rules, the adjusted calibration data is sent to the target vehicle.
