Description

Technical Field

[0001] This disclosure relates to the field of Internet of Things (IoT) technology, and in particular to a vehicle control method, apparatus, device, and storage medium. Background Technology

[0002] With the increasing development of smartphones and other mobile terminals, setting up digital car keys via mobile terminals to control vehicle functions such as unlocking has gradually become an important aspect of enhancing the user's car-using experience. In related technologies, controlling vehicle unlocking via mobile terminals requires detecting the distance between the mobile terminal and the vehicle. For example, this can be done by detecting the Received Signal Strength Indication (RSSI) value of the Bluetooth broadcast signal sent by the mobile terminal, and then querying the distance between the mobile terminal and the vehicle based on a general mapping relationship between RSSI values ​​and distance. When the distance is determined to be less than a preset threshold, an unlocking command is sent to the vehicle's lock control device to achieve the unlocking action.

[0003] However, different mobile terminals have different performance characteristics, such as different antennas, different shell materials, and different transmission powers. Using the above-mentioned general mapping relationship to detect the distance between the mobile terminal and the vehicle will result in detection errors, which will affect the accuracy of the vehicle's seamless control and cause inconvenience to the user.

[0061] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0069] Figure 7 This is a block diagram illustrating an in-vehicle terminal according to an exemplary embodiment of the present disclosure. Detailed Implementation

[0070] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0071] Figure 1 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment; the method of this embodiment can be applied to an in-vehicle terminal (the vehicle terminal is a terminal associated with a vehicle and used for data processing). Figure 1 As shown, the method includes the following steps S101-S103:

[0072] In step S101, in response to obtaining the target RSSI value of the ranging broadcast information sent by the mobile terminal, a target mapping relationship matching the device model of the mobile terminal is obtained.

[0073] In this embodiment, when the vehicle terminal obtains the target RSSI value of the ranging broadcast information sent by the mobile terminal, it can obtain a target mapping relationship that matches the device model of the mobile terminal. The target mapping relationship includes the mapping relationship between the RSSI value and the distance.

[0074] For example, the Bluetooth module (Bluetooth anchor) in the vehicle can periodically send Bluetooth broadcasts. When a mobile terminal receives this Bluetooth broadcast and detects the vehicle within its communication range, the mobile terminal can initiate a Bluetooth connection request to the vehicle's Bluetooth module, thereby establishing a Bluetooth connection. Based on this, the mobile terminal can interact with the vehicle's Bluetooth module to establish a secure channel for identity verification. After successful identity verification, the mobile terminal can send ranging broadcast information based on the Bluetooth connection (this ranging broadcast information can be periodically sent by the mobile terminal for ranging purposes when a Bluetooth connection is established with the vehicle-mounted terminal). The vehicle-mounted terminal can then receive the ranging broadcast information sent by the mobile terminal via the vehicle's Bluetooth module, measure the target RSSI (Received Signal Strength Indication) value of the ranging broadcast information, and obtain a target mapping relationship matching the mobile terminal's device model. It is understood that there can be at least one Bluetooth module in the vehicle; this embodiment does not limit this.

[0075] In some embodiments, the vehicle-mounted terminal can obtain the pre-stored target mapping relationship from a server, or obtain the pre-stored target mapping relationship from the local storage of the vehicle-mounted terminal. The server can be a local server or cloud server with data processing capabilities pre-associated with the vehicle-mounted terminal. This server can be deployed in an electronic device or a cluster of multiple electronic devices. The pre-stored target mapping relationship in this server can be a mapping relationship obtained and uploaded by the vehicle-mounted terminal or other vehicle-mounted terminals.

[0076] In other embodiments, the method by which the vehicle-mounted terminal stores the target mapping relationship can be found in the following description. Figure 2 The embodiments shown will not be described in detail here.

[0077] In step S102, the target distance corresponding to the target RSSI value is determined based on the target mapping relationship.

[0078] In this embodiment, after obtaining the target RSSI value and the target mapping relationship, the target distance corresponding to the target RSSI value can be determined based on the target mapping relationship.

[0079] Since the above target mapping relationship is a mapping between RSSI value and distance, once the target RSSI value is determined, the target distance corresponding to the target RSSI value can be queried based on this target mapping relationship. It can be understood that the target distance can be used to measure the distance between a mobile terminal and a vehicle.

[0080] In step S103, in response to the target distance being less than or equal to a preset distance threshold, the vehicle door lock associated with the vehicle terminal is unlocked.

[0081] In this embodiment, after determining the target distance corresponding to the target RSSI value based on the target mapping relationship, the vehicle terminal can compare the target distance with a preset distance threshold. Then, when the target distance is detected to be less than or equal to the preset distance threshold, the vehicle door lock is unlocked. Since no user intervention is required to unlock, this embodiment achieves seamless vehicle unlocking.

[0082] As described above, the method of this embodiment obtains a target mapping relationship matching the device model of the mobile terminal in response to the target RSSI value of the ranging broadcast information sent by the mobile terminal, and determines the target distance corresponding to the target RSSI value based on the target mapping relationship. Then, in response to the target distance being less than or equal to a preset distance threshold, it controls the vehicle door lock associated with the vehicle terminal to unlock. Since the target distance is determined based on the target mapping relationship matching the device model of the mobile terminal, compared with the method of determining distance using a general mapping relationship in related technologies, the accuracy of ranging can be improved, thereby improving the accuracy of seamless vehicle control based on the ranging results and enhancing the user's driving experience.

[0083] Figure 2 This is a flowchart illustrating how to locally store the target mapping relationship on the vehicle terminal according to an exemplary embodiment of this disclosure; this embodiment is based on the above embodiment and uses the example of how to locally store the target mapping relationship on the vehicle terminal for illustrative explanation. Figure 2 As shown, the method in this embodiment further includes storing the target mapping relationship locally on the vehicle terminal based on the following steps S201-S203:

[0084] In step S201, the reference RSSI value of the ranging broadcast information sent by the mobile terminal at at least one reference location is obtained.

[0085] In this embodiment, when the mobile terminal is detected to be at any of the above-mentioned at least one reference position, the reference RSSI value of the ranging broadcast information sent by the mobile terminal at that reference position can be obtained, wherein the distance between the above-mentioned at least one reference position and the vehicle is known.

[0086] For example, the aforementioned reference location may include a preset location around the vehicle door. Then, when the vehicle terminal detects a user's touch operation on the door (e.g., opening the door and / or gripping the door handle, where opening the door may include opening the door from inside or outside the vehicle), it can determine that the mobile terminal is currently at the preset location around the door, and can then obtain the reference RSSI value of the ranging broadcast information sent by the mobile terminal at that location.

[0087] For example, the preset position around the car door can be 0.3 meters away. That is, when a user's hand touches the door handle (which is equipped with a sensor to detect touch operation), it can be determined that the vertical distance between the user's mobile terminal and the car door is 0.3 meters. Since the distance between the vehicle's Bluetooth module and the door is known, the distance between the mobile terminal and the vehicle's Bluetooth module (i.e., the distance between the reference position and the vehicle) can be calculated. It is worth noting that the above-mentioned value of 0.3 meters is only for illustrative purposes and can be adjusted according to application requirements in actual applications.

[0088] In some embodiments, the aforementioned doors may include the driver's side door, the front passenger side door, the rear passenger side door, the trunk door, etc., but this embodiment does not limit this.

[0089] Understandably, after a Bluetooth connection is established between the mobile terminal and the Bluetooth module in the vehicle, the mobile terminal can continuously send ranging broadcast information at a set period based on this Bluetooth connection. Therefore, when a user carrying the mobile terminal triggers a touch operation on the car door, the vehicle terminal can obtain the corresponding reference RSSI value based on the ranging broadcast information currently sent by the mobile terminal.

[0090] In other embodiments, the method for obtaining the reference RSSI value of the ranging broadcast information transmitted by the mobile terminal at at least one reference location may also be described below. Figure 3 The embodiments shown will not be described in detail here.

[0091] In step S202, the currently stored mapping relationship to be corrected is corrected based on the reference RSSI value and the corresponding distance to obtain the corrected mapping relationship.

[0092] In this embodiment, after obtaining the reference RSSI value of the ranging broadcast information sent by the mobile terminal at at least one reference location, the currently stored mapping relationship to be corrected can be corrected based on the reference RSSI value and the corresponding distance to obtain the corrected mapping relationship.

[0093] The aforementioned distances can be known distances between the reference position and the vehicle, which are pre-measured, such as the distances between each door of the vehicle and the Bluetooth module.

[0094] In some embodiments, after obtaining the reference RSSI value of the ranging broadcast information sent by the mobile terminal at at least one reference location, the distance corresponding to the corresponding RSSI value in the currently stored mapping relationship to be corrected can be replaced based on the reference RSSI value and the corresponding distance. Furthermore, the distances corresponding to other RSSI values ​​in the above-mentioned mapping relationship to be corrected can be uniformly corrected based on known signal attenuation rules or a preset interpolation algorithm, thereby achieving the correction of the currently stored mapping relationship to be corrected. It is worth noting that the aforementioned signal attenuation rules or preset interpolation algorithms can be selected from related technologies based on actual needs, and this embodiment does not limit them.

[0095] In step S203, the corrected mapping relationship is stored locally on the vehicle terminal as a target mapping relationship that matches the device model of the mobile terminal.

[0096] In this embodiment, when the currently stored mapping relationship to be corrected is corrected based on the reference RSSI value and the corresponding distance, and the corrected mapping relationship is obtained, the corrected mapping relationship can be used as the target mapping relationship matching the device model of the mobile terminal and stored locally on the vehicle terminal.

[0097] For example, if the vehicle terminal has not previously stored a target mapping relationship matching the mobile terminal's device model locally, the modified mapping relationship described above can be used as the target mapping relationship matching the mobile terminal's device model and stored locally on the vehicle terminal. Conversely, if the vehicle terminal has previously stored a target mapping relationship matching the mobile terminal's device model locally, the modified mapping relationship described above can be used as the updated target mapping relationship, replacing the previously stored target mapping relationship stored locally on the vehicle terminal. Furthermore, when the vehicle terminal subsequently needs to use the target mapping relationship, it can directly retrieve it from its local storage.

[0098] Furthermore, such as Figure 2 As shown, the method in this embodiment may further include the following step S204:

[0099] In step S204, the corrected mapping relationship is uploaded to the server for storage as the target mapping relationship that matches the device model of the mobile terminal.

[0100] In this embodiment, after correcting the currently stored mapping relationship based on the reference RSSI value and the corresponding distance to obtain the corrected mapping relationship, the corrected mapping relationship can also be uploaded to the server as a target mapping relationship that matches the device model of the mobile terminal for storage, so that other vehicle terminals can download the target mapping relationship from the server in the future.

[0101] The aforementioned mapping relationship to be corrected can be a general mapping relationship that does not distinguish between device models in related technologies, or it can be a target mapping relationship previously stored in the vehicle terminal. This embodiment does not limit this.

[0102] For example, the vehicle terminal can first send a request to the server to obtain the aforementioned target mapping relationship. If the server stores the target mapping relationship, it can return the target mapping relationship to the vehicle terminal based on the request. If the server does not store the target mapping relationship, it can return a feedback message to the vehicle terminal indicating that the mapping relationship does not exist. Then, the vehicle terminal can obtain the target mapping relationship through the steps S201-S203 described above.

[0103] As described above, this embodiment obtains the reference RSSI value of the ranging broadcast information sent by the mobile terminal at at least one reference location, where the distance between the at least one reference location and the vehicle is known. Based on the reference RSSI value and the corresponding distance, the currently stored mapping relationship to be corrected is corrected to obtain the corrected mapping relationship. The corrected mapping relationship is then used as the target mapping relationship matching the device model of the mobile terminal and stored locally on the vehicle terminal and / or uploaded to the server. This enables the direct acquisition of the target mapping relationship, improves the efficiency of acquiring the target mapping relationship, and improves the accuracy of ranging based on RSSI values. Consequently, it improves the accuracy of seamless vehicle control based on ranging results and enhances the user's driving experience.

[0104] Figure 3 This is a flowchart illustrating how to obtain the reference RSSI value of ranging broadcast information transmitted by the mobile terminal at at least one reference location, according to an exemplary embodiment of this disclosure. This embodiment, based on the above embodiment, provides an illustrative example of how to obtain the reference RSSI value of ranging broadcast information transmitted by the mobile terminal at at least one reference location. Figure 3 As shown, obtaining the reference RSSI value of the ranging broadcast information sent by the mobile terminal at at least one reference location in step S201 above may include the following steps S301-S302:

[0105] In step S301, a prompt message is generated to prompt the sending of confirmation information at the reference location.

[0106] In this embodiment, when the vehicle terminal detects that the conditions for correcting the target mapping relationship are met, it can generate a prompt message to prompt the user to send confirmation information based on the mobile terminal at the reference location. The confirmation information is used to confirm that the mobile terminal is at the reference location.

[0107] In some embodiments, the condition for detecting that the modified target mapping relationship is satisfied may include at least one of the following (1) to (3):

[0108] (1) Detecting a user-triggered instruction to correct the target mapping relationship, such as if the user thinks the vehicle unlocking time is not accurate enough after using the vehicle for a period of time, the user can manually trigger the instruction to correct the target mapping relationship.

[0109] (2) The system initialization process of the vehicle terminal was detected;

[0110] (3) The current time reaches the preset period for the target mapping relationship correction. The preset period can be set according to actual needs, such as 1 month, half a year or 1 year, etc. This embodiment does not limit this.

[0111] In some embodiments, the reference position may include the four corners of the vehicle and / or a preset position around the door, etc., and this embodiment does not limit this.

[0112] In step S302, in response to receiving the confirmation information, the reference RSSI value of the ranging broadcast information currently sent by the mobile terminal is obtained.

[0113] In this embodiment, after the vehicle terminal receives the confirmation information sent by the user based on the mobile terminal, it can determine that the mobile terminal is currently at a reference position with a known distance. Then, it can obtain the reference RSSI value of the ranging broadcast information currently sent by the mobile terminal, and subsequently correct the currently stored mapping relationship based on this reference RSSI value and the corresponding distance. For detailed explanations and descriptions, please refer to the above. Figure 2 The embodiments shown are not described in detail here.

[0114] As described above, this embodiment generates a prompt message to prompt the user to send confirmation information at the reference location, and in response to receiving the confirmation message, obtains the reference RSSI value of the ranging broadcast information currently sent by the mobile terminal. This enables the user to be guided to send ranging broadcast information at at least one reference location, thereby obtaining the reference RSSI value of the ranging broadcast information sent by the mobile terminal at at least one reference location. This allows for subsequent correction of the currently stored mapping relationship to obtain the target mapping relationship.

[0115] Figure 4 This is a flowchart illustrating how to replace the pre-stored target mapping relationship according to an exemplary embodiment of this disclosure; this embodiment further includes steps S401-S403 based on the above embodiment:

[0116] In step S401, a timer is started in response to controlling the vehicle door lock associated with the vehicle terminal to unlock.

[0117] In this embodiment, when the vehicle door lock associated with the vehicle terminal is unlocked in step S103, the timer can be started.

[0118] It is worth noting that the above-mentioned method of starting the timer can be selected based on actual needs, such as choosing the method of starting the timer, etc., and this embodiment does not limit this.

[0119] In step S402, the target mapping relationship is adjusted in response to the time interval between the start of timing and the detection of an operation to touch the driver's side door of the vehicle being greater than or equal to a set time threshold.

[0120] In this embodiment, when the time interval between the start of timing and the detection of an operation to touch the driver's side door of the vehicle is greater than or equal to a set time threshold, the target mapping relationship can be adjusted.

[0121] It is worth noting that the above-mentioned time threshold can be set according to actual needs, such as setting it to 3 seconds, etc. This embodiment does not limit this.

[0122] It is worth noting that the aforementioned time interval refers to the time it takes for the user to walk to the car door and open it after the vehicle has unlocked. Understandably, if this time is too long, it indicates that the vehicle is unlocking too early, which could easily lead to vehicle safety issues. Therefore, the target mapping relationship needs to be adjusted.

[0123] Specifically, in this embodiment, when the target distance corresponding to the target RSSI value is detected to be less than or equal to a preset distance threshold, the vehicle door lock associated with the vehicle terminal is unlocked. If the time interval between the start of timing and the detection of the operation of touching the driver's side door of the vehicle is greater than or equal to a set time threshold, it indicates that the actual distance corresponding to the target RSSI should be greater than the target distance. Therefore, the target mapping relationship can be adjusted based on a preset adjustment method, such as increasing the distance value corresponding to each RSSI value. The specific adjustment range can be determined based on experience or through experiments. This embodiment does not limit this.

[0124] In step S403, the pre-stored target mapping relationship is updated based on the adjusted target mapping relationship.

[0125] In this embodiment, after the target mapping relationship is adjusted, the pre-stored target mapping relationship can be updated based on the adjusted target mapping relationship, such as replacing the original target mapping relationship stored locally or on the server side of the vehicle terminal based on the adjusted target mapping relationship for subsequent use.

[0126] As described above, this embodiment starts timing in response to the vehicle door lock being unlocked by the control unit associated with the vehicle terminal, and adjusts the target mapping relationship in response to the time interval between the start of timing and the detection of an operation to touch the driver's side door of the vehicle being greater than or equal to a set time threshold. Then, based on the adjusted target mapping relationship, the pre-stored target mapping relationship is updated. This allows for adjustment of the target mapping relationship based on its actual usage, further improving the accuracy of the target mapping relationship and consequently enhancing the accuracy of distance measurement based on it.

[0127] Figure 5 This is a block diagram illustrating a vehicle control device according to an exemplary embodiment of the present disclosure; the device of this embodiment can be applied to an in-vehicle terminal (the vehicle terminal is a terminal associated with a vehicle and used for data processing). Figure 5 As shown, the device includes: a mapping relationship acquisition module 110, a target distance determination module 120, and a vehicle unlocking control module 130, wherein:

[0128] The mapping relationship acquisition module 110 is used to acquire a target mapping relationship matching the device model of the mobile terminal in response to acquiring the target RSSI value of the ranging broadcast information sent by the mobile terminal. The target mapping relationship includes the mapping relationship between the RSSI value and the distance.

[0129] The target distance determination module 120 is used to determine the target distance corresponding to the target RSSI value based on the target mapping relationship;

[0130] The vehicle unlocking control module 130 is used to control the vehicle door lock associated with the vehicle terminal to unlock in response to the target distance being less than or equal to a preset distance threshold.

[0131] As described above, the device in this embodiment obtains a target mapping relationship matching the device model of the mobile terminal in response to receiving the target RSSI value of the ranging broadcast information sent by the mobile terminal, and determines the target distance corresponding to the target RSSI value based on the target mapping relationship. Then, in response to the target distance being less than or equal to a preset distance threshold, it controls the vehicle door lock associated with the vehicle terminal to unlock. Since the target distance is determined based on the target mapping relationship matching the device model of the mobile terminal, compared with the method of determining distance using a general mapping relationship in related technologies, the accuracy of ranging can be improved, thereby improving the accuracy of seamless vehicle control based on the ranging results and enhancing the user's driving experience.
