[0028] Embodiment 1

[0029] Figure 1 This is a flow chart of a digital key control method provided according to the first embodiment of the present invention. This embodiment is applicable to the case of intelligently controlling the digital key of a vehicle. The method can be executed by a digital key control device. The digital key control device can be implemented in the form of hardware and / or software. The digital key control device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0030] S110, obtaining regional data of the digital key and sensor data of the mobile terminal.

[0031] Among them, the mobile terminal is the carrier of the digital key. The mobile terminal may include but is not limited to smart devices such as smart phones, smart watches or bracelets. The digital key may be a Bluetooth digital key. In this embodiment, the Bluetooth BLE digital key is usually equipped with 4 or 5 Bluetooth BLE anchor points on the car, of which at least one anchor point is installed in the car. The digital key is used to control operations such as unlocking or locking the target vehicle. The target vehicle may be a vehicle corresponding to the target user. The regional data can be understood as the sensing area where the digital key is located. In this embodiment, the regional data of the digital key refers to the sensing area where the digital key is located based on the Bluetooth strength of the digital key. The regional data may specifically include the welcome area, the unlocking area, the unlocking area, and the connection area, which can be set according to actual conditions. The sensor data can be understood as the smart sensor hub data in the mobile terminal. The mobile terminal in this embodiment may be a smart phone, and its sensor data may be the mobile phone Sensor Hub data. Specifically, in this embodiment, the accelerometer and global position GNSS data provided in the mobile phone Sensor Hub can be obtained. Among them, the GNSS data mainly refers to the position, speed, time and other information provided by the Global Navigation Satellite System.

[0032] In this embodiment, the current sensing area of ​​the digital key corresponding to the vehicle and the accelerometer data and global positioning data of the mobile terminal can be obtained.

[0033] S120: Determine a target behavior trend of the target user according to the area data and the sensor data.

[0034] The target behavior trend can be understood as the movement behavior trend of the target user relative to the vehicle. In this embodiment, the target behavior trend can include a behavior trend of approaching the vehicle, a behavior trend of moving away from the vehicle, and a behavior trend of staying in place.

[0035] In this embodiment, the movement trend of the target user relative to the target vehicle, that is, the target behavior trend, can be detected based on the real-time acquired data of the area where the digital key is located, the accelerometer and global position GNSS data provided by the smartphone Sensor Hub, and the receiving power of the N BLE anchor points carried by the target vehicle.

Specifically, the method of controlling the digital key based on the target behavior trend of the target user can be: when the target behavior trend of the target user is the approaching behavior trend, the digital key is controlled to perform an unlocking operation; when the target behavior trend of the target user is the moving away behavior trend, the digital key is controlled to perform a locking operation. When the target behavior trend of the target user is the staying in place behavior trend, the digital key is not controlled.

[0038] The technical solution of the embodiment of the present invention obtains the regional data of the digital key and the sensor data of the mobile terminal; wherein the mobile terminal is the carrier of the digital key; determines the target behavior trend of the target user according to the regional data and the sensor data; and controls the digital key based on the target behavior trend of the target user. This technical solution determines the user's behavior trend through the sensor data that can be obtained in the mobile terminal, and then controls the digital key, thereby improving the accuracy of the control of the digital key and enhancing the user experience of the digital key.

[0039] Embodiment 2

[0040] Figure 2 This is a flow chart of a digital key control method provided according to the second embodiment of the present invention, and this embodiment is optimized based on the above embodiment. The specific optimization is as follows: the sensor data includes acceleration data and position data; the target behavior trend of the target user is determined based on the area data and the sensor data, including: determining the motion state of the target user based on the acceleration data; when the motion state is a non-stationary state, reading the location data of the mobile terminal in real time; determining the initial behavior trend based on the position data and the area data, and updating the state flag based on the initial behavior trend; determining the target behavior trend of the target user based on the initial behavior trend, the state flag and the position data. Figure 2 As shown, the method includes:

[0041] S210: Acquire regional data of the digital key and sensor data of the mobile terminal.

[0042] The mobile terminal is the carrier of the digital key; the sensor data includes acceleration data and position data. The acceleration data can be understood as the data read by the accelerometer. The position data can be understood as the position coordinates, speed, time and other information provided by the Global Navigation Satellite System in the mobile terminal.

[0043] S220: Determine the motion state of the target user according to the acceleration data.

[0044] The target user's motion state may be the current state of the user determined by analyzing and processing the acceleration data reading. In this embodiment, the target user's motion state may include four motion states: static state, shaking state in place, walking state, and disordered shaking state in movement.

[0045] Specifically, in this embodiment, it is necessary to obtain the acceleration data of the target user at different time points through an acceleration sensor. These acceleration data are usually represented in the form of three-dimensional vectors, corresponding to the acceleration values ​​on the x, y, and z axes, respectively. The modulus, standard deviation, total energy and low-frequency energy are calculated according to the acceleration values ​​on the x, y, and z axes. Based on the calculated modulus, standard deviation, total energy, low-frequency energy and other information, a judgment basis can be designed to judge the user's motion state, thereby obtaining the target user's motion states such as static state, shaking state in place, walking state, and disordered shaking state while moving.

[0046] S230: When the motion state is not a stationary state, read the location data of the mobile terminal in real time.

[0047] The location data may be the latest location data acquired through real-time updates. In this embodiment, the area where the digital key is located and the Bluetooth signal strength sliding window may be updated in real time, and the acceleration value read by the mobile terminal API and the location coordinate information read by the mobile terminal API may also be updated in real time. In this embodiment, the area data and the location data and acceleration data in the sensor data have their corresponding sliding windows to store their respective corresponding data.

[0048] In this embodiment, when the target user's motion state is non-stationary, that is, when the target user's motion state is any state of shaking in place, walking, or disordered shaking during movement, the location information of the mobile terminal will be obtained in real time, the location coordinate data read by the mobile phone API will be updated in real time, and the sliding window of N seconds will be maintained; and the accuracy of the location coordinates and the motion state of the target user will be monitored in real time; if the accuracy of the location coordinates is too poor or the motion state of the target user changes, the location coordinate sliding window can be reset to re-update the location coordinate data read by the mobile phone API. Among them, N seconds can be a sliding window of 3-4 seconds, which can maintain a window data of relatively good quality, so as to obtain relatively good positioning data.

[0049] In this embodiment, when the user's motion state is a stationary state, it can be detected that the user's behavior trend is a staying in place behavior trend, and no further analysis and processing is required.

[0050] S240: Determine an initial behavior trend according to the location data and the area data, and update a status flag based on the initial behavior trend.

[0051] Among them, the initial behavior trend can be understood as the possible behavior trend of the target user. In this embodiment, the possible behavior trend of the target user can be preliminarily determined based on the location coordinate data and the area data. The initial trend of approaching the vehicle includes the initial trend of approaching the vehicle and the initial trend of moving away from the vehicle. Among them, the initial trend of approaching the vehicle can be understood as a possible trend of approaching the vehicle behavior; the initial trend of moving away from the vehicle can be understood as a possible trend of moving away from the vehicle behavior. The state flag can be understood as the identifier corresponding to the different behavior states corresponding to the initial behavior trend. In this embodiment, the state flag may include a state flag corresponding to the behavior state of the initial trend of approaching the vehicle, and a state flag corresponding to the behavior state of the initial trend of moving away from the vehicle.

[0052] Specifically, in this embodiment, it can be determined whether the target user is walking from inside the car to outside the car based on the location information obtained by the mobile terminal and the area information of the digital key. If the target user is walking from inside the car to outside the car, the initial behavior trend of the target user is that he may walk away from the vehicle, that is, he may walk away from the vehicle, and its corresponding status flag checkFlag can be updated to CHECK_AWAY_IN_OUT, that is, the mark of walking from inside the car to outside the car; if the target user is not walking from inside the car to outside the car, it is continued to be determined whether the target user is walking from the unlocking area to the locking area based on the location information obtained by the mobile terminal and the area information of the digital key. If the target user is walking from the unlocking area to the locking area, it is determined that the initial behavior trend of the target user is The behavior trend of moving away from the vehicle, that is, there is a possibility of moving away from the vehicle, and its corresponding status flag checkFlag can be updated to CHECK_AWAY_PE_LOCK, which is an indication of moving from the unlocking area to the locking area; if the target user is not moving from the unlocking area to the locking area, it is determined whether the target user is located in the connection area, the welcome area or the locking area based on the location information obtained by the mobile terminal and the area information of the digital key. If the target user is located in the connection area, the welcome area or the locking area, it is determined that the initial behavior trend of the target user is the initial approach to the vehicle trend, that is, there is a possibility of approaching the vehicle, and its corresponding status flag checkFlag can be updated to CHECK_APPROACH.

[0053] In this embodiment, the initial behavior trend away from the vehicle corresponds to two status flags, and the initial behavior trend towards the vehicle corresponds to one status flag. In this embodiment, the initial behavior trend of the target user can be determined based on the sensing area where the digital key is located and the real-time location data, and the status flag can be updated according to the status corresponding to the initial behavior trend.

[0054] S250: Determine a target behavior trend of the target user according to the initial behavior trend, the state flag, and the location data.

[0055] The target behavior trend can be understood as the behavior trend of the vehicle corresponding to the target user that is finally determined. In this embodiment, the target behavior trend can include a behavior trend of approaching the vehicle and a behavior trend of moving away from the vehicle.

[0056] In this embodiment, if the initial behavior trend is an initial approaching vehicle trend, the algorithm logic of the approaching trend operator is executed according to the state flag corresponding to the target user behavior state of the initial approaching vehicle trend and the real-time location data to determine whether the target user's final behavior trend is an approaching vehicle behavior trend. If the initial behavior trend is a moving away from the vehicle trend, the algorithm logic of the moving away trend operator is executed according to the state flag corresponding to the target user behavior state of the initial moving away from the vehicle trend and the real-time location data to determine whether the target user's final behavior trend is a moving away from the vehicle behavior trend.

[0057] In this embodiment, optionally, the initial behavior trend includes an initial trend away from the vehicle; determining the target behavior trend of the target user based on the initial behavior trend, the status flag and the position data, including: when the initial behavior trend is the initial trend away from the vehicle, judging whether the sliding window data has a target away heading angle; if the sliding window data does not have a target away heading angle, determining a first heading angle and a first distance based on the status flag and multiple position data; determining the target away heading angle based on the first heading angle, and determining the target behavior trend based on the target away heading angle and the first distance.

[0058] Among them, the sliding window data can be understood as a sliding window for storing calculated data, and in this embodiment, it can be used to store the calculated heading angle data and other data information. The target away heading angle can be understood as the away heading angle calculated when the target behavior trend is determined to be a away behavior trend. In this embodiment, the away heading angle corresponding to each time the target behavior trend is determined to be a away from the vehicle trend by the algorithm logic of the away trend operator can be used as the target away heading angle, and the target away heading angle is stored in the sliding window so as to be used as a judgment basis or reference information when the judgment logic is looped.

[0059] Among them, multiple location data can be understood as location coordinate data within a set time period. In this embodiment, if the status flag is checkFlag is CHECK_AWAY_IN_OUT, the GNSS coordinates of the target user just when he gets out of the car are recorded, and the GNSS coordinates of the user in motion in the next N seconds are continuously recorded as multiple location coordinate data. If the status flag is checkFlag is CHECK_AWAY_PE_LOCK, the real-time location coordinates of the target user within the current set time length are recorded as multiple location coordinate data. Among them, within N seconds can be at least within 3 seconds.

[0060] Among them, the number of first heading angles and first distances corresponds to the number of position data. The first heading angle may include multiple heading angles. In this embodiment, each position data can be determined by calculation to obtain a corresponding distance data and heading angle. Therefore, the number of first heading angles and the number of first distances in this embodiment can depend on the number of position data. Exemplarily, in this embodiment, if the corresponding three position coordinates can be determined within at least 3 seconds, the three position coordinate data are the first position coordinate, the second position coordinate, and the third position coordinate, respectively. The heading angle and distance from the first position coordinate to the second position coordinate, the heading angle and distance from the first position coordinate to the third position coordinate, and the heading angle and distance from the second position coordinate to the third position coordinate can be calculated respectively.

[0061] In this embodiment, when determining the possibility that the initial behavior trend is the initial trend of moving away from the vehicle, first determine whether the sliding window data contains the target moving away heading angle, that is, determine whether the target moving away heading angle has been calculated; if the sliding window data does not contain the target moving away heading angle, then the target moving away heading angle can be calculated. Specifically, since there are two corresponding status flags for the initial trend of moving away from the vehicle in this embodiment, in this embodiment, it can be determined whether the status flag is CHECK_AWAY_IN_OUT. If the status flag is CHECK_AWAY_IN_OUT, the GNSS coordinate data of the target user's position when he just got out of the car is recorded, and the GNSS coordinates of the target user's position in the next N seconds are continuously recorded. Among them, the N seconds here can be at least 3 seconds, which can be set according to actual needs. Then, the first heading angle and the first distance are calculated based on the position data of the target user when he just got out of the car and the corresponding multiple position data within at least 3 seconds. In this embodiment, the heading angle average can be calculated based on the multiple heading angles included in the first heading angle, and the heading angle average is used as the target away from the heading angle, and it is determined whether the multiple heading angles in the first heading angle meet the corresponding heading angle threshold requirements and whether the first distance meets the corresponding distance threshold requirements; if the multiple heading angles and multiple distance data meet the corresponding threshold requirements respectively, then the target behavior trend is determined to be away from the vehicle behavior trend. Among them, the heading angle threshold requirement and the distance threshold requirement can be pre-set. Exemplarily, the heading angle in this embodiment is used to characterize the current running direction of the target user, the heading angle threshold can be within 75 degrees, and the distance threshold requirement can be set to within 10 meters. In this embodiment, it can be set according to actual needs. In this embodiment, a total heading angle can be determined by calculating the target away angle, which is used to determine whether the current direction is consistent and consistent with changing in a stable direction.

[0062] Furthermore, in this embodiment, if multiple heading angles in the first heading angle do not meet the corresponding heading angle threshold requirements and / or each distance in the first distance does not meet the corresponding distance threshold requirements, the check flag of the initial behavior trend can be reset, indicating that the target user has no obvious behavior trend at this time.

[0063] Through such a setting in the present embodiment, the possibility of the initial trend being the trend away from the vehicle can be determined, and then the heading angle and distance of the target user's coordinate data can be determined, thereby determining the target behavior trend of the target user, thereby improving the reliability of the target behavior trend judgment and the turning curve, so as to accurately control the digital key.

[0064] In this embodiment, optionally, the status flag includes a first status flag and a second status flag; determining the first heading angle and the first distance based on the status flag and multiple position data includes: when the status flag is the first status flag, determining the first heading angle and the first distance based on multiple position data within a specified time period; when the status flag is the second status flag, determining the first heading angle and the first distance based on multiple position data acquired in real time.

[0065] The first flag may be CHECK_AWAY_IN_OUT, which is a flag corresponding to the state where the target user is walking from inside the car to outside the car. The second flag may be CHECK_AWAY_PE_LOCK, which is a flag corresponding to the state where the target user is walking from the unlocking area to the locking area. The specified duration may be when the target user just leaves the car and within at least 3 seconds of continuous recording.

[0066] In this embodiment, when the status flag is the first status flag, that is, CHECK_AWAY_IN_OUT, multiple position data corresponding to the target user just getting out of the car and continuously recorded for at least 3 seconds can be obtained, and the first heading angle and the first distance can be determined based on the determined multiple data; when the status flag is the second status flag, that is, CHECK_AWAY_PE_LOCK, multiple position data obtained in real time at the current moment can be obtained to determine the first heading angle and the first distance.

[0067] In this embodiment, different position coordinate data can be determined according to different determined status flags, thereby determining different heading angles and distance data, thereby improving the accuracy of data under different user states and improving the accuracy of user behavior state judgment.

[0068] In this embodiment, optionally, it also includes: if there is a target moving away from the heading angle, calculating the second heading angle and the second distance based on the current position data; comparing the second heading angle with the heading angle at which the target moves away, and continuing to judge whether the second heading angle and the second distance meet the first set threshold based on the comparison result, and determining the motion trajectory based on the heading angle at which the target moves away and the second heading angle; when the second heading angle and the second distance meet the first set threshold, and the motion trajectory moves away from the first initial coordinate, determining that the target behavior trend of the target user is a behavior trend moving away from the vehicle.

[0069] Among them, the first initial coordinate is determined based on the heading angle of the target away. The first initial coordinate in this embodiment can be understood as the initial position coordinates for calculating the first calculation of the heading angle of the target away. The current moment position data is the real-time position coordinate data of the current moment in the position data sliding window. The second heading angle can be understood as the heading angle determined according to the current moment position data. The second distance can be understood as the distance data calculated according to the current moment position data. The first set threshold can be understood as a pre-set threshold. The first set threshold in this embodiment may include a heading angle threshold and a distance threshold.

[0070] In this embodiment, when the possibility of determining that the initial behavior trend is the initial trend away from the vehicle is determined, by judging that the current sliding window data has a target away heading angle, that is, the away heading angle has been calculated, then the second heading angle and the second distance are calculated according to the corresponding position data in the GNSS sliding window at the current moment, and the second heading angle is compared with the target away heading angle to determine whether the two heading angles are close, so as to determine whether the target user is moving in this direction. In this embodiment, if the second heading angle is very close to the target away heading angle and the angle is relatively small, it can be further determined whether the second heading angle and the second distance meet the heading angle threshold and the distance threshold in the first set threshold, and the movement trajectory of the target user is determined based on the target away heading angle and the second heading angle; when the second heading angle and the second distance meet the heading angle threshold and the distance threshold in the first set threshold, and the movement trajectory is away from the first initial coordinate corresponding to the first determined target away heading angle, it can be determined that the target behavior trend of the target user is the trend away from the vehicle.

[0071] Furthermore, in this embodiment, when the second heading angle and the second distance do not satisfy the heading angle threshold and the distance threshold in the first set threshold, and the motion trajectory does not move away from the first initial coordinate corresponding to the heading angle determined for the first time when the target is away from the target, it is determined whether the target user has deviated from the running direction. If the target user has deviated from the running direction, the turning flag can be set and the relevant variables can be reset. At this time, it can be determined that the behavior trend of the target user has no obvious behavior trend.

[0072] Through such a setting in this embodiment, the corresponding heading angle and distance are determined based on different location data to judge the final behavior trend of the target user, thereby improving the reliability and accuracy of user behavior trend judgment and avoiding erroneous operation of the digital key when the Bluetooth signal is unstable.

[0073] In this embodiment, optionally, the initial behavior trend includes an initial trend of approaching the vehicle; determining the target behavior trend of the target user based on the initial behavior trend, the status flag and the position data, including: when the initial behavior trend is the initial trend of approaching the vehicle, judging whether the signal change trend of the Bluetooth anchor point satisfies the set signal condition; if the signal change trend of the Bluetooth anchor point satisfies the set signal condition, judging whether there is a target approaching heading angle in the sliding window data; if the sliding window data does not contain a target approaching heading angle, determining a third heading angle and a third distance based on the current multiple position data; determining the target approaching heading angle based on the third heading angle, and determining the target behavior trend based on the target approaching heading angle and the third distance.

[0074] Among them, setting the signal condition may be a condition for setting the signal of the Bluetooth anchor point, and in the present embodiment, the setting of the signal condition may be pre-set. In the present embodiment, the setting of the signal condition may be a characteristic of a gradually enhanced Bluetooth signal, that is, an approaching vehicle. The target approach heading angle may refer to an approach heading angle calculated when it is determined that the target behavior trend is an approaching behavior trend. In the present embodiment, each time the target behavior trend is determined by the algorithm logic of the approach trend operator to be an approaching vehicle trend, the corresponding approach heading angle may be used as the target approach heading angle, and the target approach heading angle may be stored in a sliding window so as to be used as a basis for judgment or reference information in the loop judgment logic.

[0075] The number of the third heading angle and the third distance corresponds to the number of the position data; the third heading angle may include multiple heading angles, and in this embodiment, each position data can be determined by calculation to obtain a corresponding distance data and heading angle, so the number of the third heading angle and the number of the third distance in this embodiment can depend on the number of the current multiple position data. Exemplarily, in this embodiment, if the number of the current multiple position data is 3, the third heading angle and the third distance are determined based on 3 position coordinate data, then the third heading angle may include three heading angle data, and the third distance may include three distance data.

[0076] When determining the possibility that the initial behavior trend is the initial trend away from the vehicle, first determine whether the signal change trend of the Bluetooth anchor point meets the set signal conditions, that is, whether it meets the characteristics of approaching the vehicle. If the signal change trend of the Bluetooth anchor point meets the set signal conditions, continue to determine whether there is a target approaching heading angle in the sliding window data, that is, determine whether the target approaching heading angle has been calculated; if the sliding window data does not contain a target approaching heading angle, then you can start calculating the target approaching heading angle, and you can calculate the corresponding heading angle and distance respectively according to the multiple position data in the current GNSS coordinate sliding window. You can determine whether the heading angle and distance meet the corresponding threshold requirements, and then continue to calculate the target approaching heading angle.

[0077] Furthermore, in this embodiment, if the sliding window data contains a target approaching heading angle, a fourth heading angle and a fourth distance are determined based on the current multiple position data; wherein the number of fourth heading angles and fourth distances corresponds to the number of position data; and when the fourth heading angle and the fourth distance satisfy the third set threshold, the target behavior trend is determined to be an approaching vehicle behavior trend.

[0078] Among them, the third set threshold may include a heading angle threshold and a distance threshold. In this embodiment, if the sliding window data has a target approaching heading angle, a fourth heading angle and a fourth distance are determined according to the current multiple position data in the current GNSS coordinate sliding window, and compared with the target approaching heading angle, and whether the fourth heading angle and the fourth distance meet the third set threshold is further determined according to the comparison result. If the fourth heading angle and the fourth distance meet the third set threshold, the target behavior trend is determined to be an approaching vehicle behavior trend.

[0079] In this embodiment, the specific method of determining the approaching heading angle of the target according to the third heading angle is to calculate the heading angle average according to the multiple heading angles included in the third heading angle, and use the heading angle average as the heading angle of the target moving away. Then, the corresponding target behavior trend is determined by judging the calculated heading angle of the target moving away, the third distance, and the third heading angle through the set threshold requirement.

[0080] Through such a setting in the present embodiment, in the case of the initial approach trend, the corresponding heading angle and distance are determined based on different position data to determine the final behavior trend of the target user, thereby improving the reliability and accuracy of user behavior trend judgment and avoiding erroneous operation of the digital key when the Bluetooth signal is unstable.

[0081] In this embodiment, optionally, the target approach heading angle is determined based on the third heading angle, and the target behavior trend is determined based on the target approach heading angle and the third distance, including: when the third heading angle and the third distance meet a second set threshold, determining the target approach heading angle based on the third heading angle; and determining the target behavior trend as an approaching vehicle behavior trend based on the target approach heading angle.

[0082] The second set threshold may include a heading angle threshold and a distance threshold. In this embodiment, when multiple heading angles in the third heading angle all meet the corresponding set heading threshold and the third distance all meet the corresponding distance threshold, the heading angle average can be calculated according to the multiple heading angles included in the third heading angle, and the heading angle average is used as the target away from the heading angle, and the current motion trajectory is determined to gradually move away from the first initial coordinate according to the target approaching heading angle, and the target behavior trend of the target user is determined to be the away from the vehicle behavior trend.

[0083] In this embodiment, if multiple heading angles in the third heading angle do not meet the corresponding set heading threshold and the third distances meet the corresponding distance threshold, the check flag of the initial trend is reset. In this case, the target user has no obvious behavioral trend.

[0084] In addition, in this embodiment, if the difference between the current heading angle and the approaching heading angle or the away heading angle is within a certain threshold range, it can be determined whether the target user has the possibility of turning around; if the target user has the possibility of turning around, it is necessary to recalculate the approaching heading angle or the away heading angle. Exemplarily, if the difference between the current heading angle and the approaching heading angle, or the difference between the current heading angle and the away heading angle is within the threshold range of -150 to 150 degrees, it is determined that the target user may have a tendency to turn around, and TURN_FLAG is set to 1. At this time, the approaching or away heading angle needs to be recalculated.

[0085] In this embodiment, through such a setting, the approach behavior trend of the target user is determined based on the calculated heading angle and distance, thereby improving the reliability and accuracy of user behavior trend determination.

[0086] S260. Control the digital key based on the target behavior trend of the target user.

[0087] The embodiment of the present invention integrates multiple sensor technologies, including Bluetooth, accelerometer, satellite positioning and other data, to provide user behavior trend assistance for the realization of digital key functions, enhance the stability of existing Bluetooth digital keys in complex environments, and to a certain extent solve the related pain points of the prior art, such as incorrect unlocking, ping-pong effect, etc.; moreover, the embodiment of the present invention is not limited to mobile terminals, or smartphone brands and models, and does not limit the layout of Bluetooth BLE anchor points on vehicles, and has wide adaptability.

[0088] The technical solution of the embodiment of the present invention is to obtain the regional data of the digital key and the sensor data of the mobile terminal; wherein the mobile terminal is the carrier of the digital key; the sensor data includes acceleration data and position data; determine the motion state of the target user according to the acceleration data; read the position data of the mobile terminal in real time when the motion state is not static; determine the initial behavior trend according to the position data and the regional data, and update the state flag based on the initial behavior trend; determine the target behavior trend of the target user according to the initial behavior trend, the state flag and the position data; and control the digital key based on the target behavior trend of the target user.
