Description

Technical Field

[0001] The present application relates to the field of vehicle key connection, and more specifically, to a digital key control method, device, electronic device and medium. Background Art

[0002] With the increasing popularity of digital car keys, the third generation of digital keys (NFC+BLE+UWB) has made great progress in smart cars. NFC stands for Near Field Communication, BLE stands for Bluetooth Low Energy, and UWB stands for Ultra-Wideband. Mobile phones, watches, bracelets, and BLE physical keys are car keys, which are smart keys based on BLE connections. BLE physical keys are powered by batteries with small capacity and cannot be charged, so their power consumption needs to be reduced within a certain range, otherwise the physical keys will have to replace batteries frequently. Smart keys such as mobile phones, watches, and bracelets have large battery capacity and can be charged, so their power consumption does not restrict key performance.

[0003] According to the power consumption characteristics of Bluetooth broadcast and scanning, the BLE physical key generally sends connection broadcasts at a certain period, and the vehicle scans the broadcasts to connect, so as to reduce the power consumption of the physical key; while the mobile phone, watch, and bracelet key scan the vehicle broadcast, and the mobile phone, watch, and bracelet key create a Bluetooth connection. Before the Bluetooth connection between the BLE physical key and the vehicle is established, the Bluetooth module on the physical key sends the connection broadcast as a broadcaster, and the Bluetooth module on the vehicle scans the connection broadcast sent by the BLE physical key as a scanner.

[0004] During the Bluetooth connection process, the party responsible for scanning opens the scanning window period, and within the scanning window period, if the target broadcast is scanned, the connection with the target broadcast can be initiated; the Bluetooth module of the digital key control device on the vehicle side is responsible for sending broadcasts to be scanned by mobile phones, watches, and bracelet keys, and also for scanning broadcasts sent by BLE physical keys. In addition, under the requirement of multi-key connection, it is also responsible for broadcasting and scanning during Bluetooth communication. Therefore, the Bluetooth module of the digital key control device on the vehicle side cannot use 100% of the time slice to scan the Bluetooth broadcast of the BLE physical key, which may result in a slow connection establishment when the BLE physical key is close to the car, and may even cause the BLE physical key to still not take effect when the user reaches the car door.

[0005] In view of this, this application is hereby filed. Summary of the invention

[0006] The purpose of the present application is to provide a digital key control method, device, electronic device and medium to solve the problem of slow connection speed of vehicle-side digital key to BLE physical key in the prior art.

[0022] When at least one of the second Bluetooth modules scans the broadcast information, acquiring a notification message sent by the second Bluetooth module;

[0023] According to the notification message, the scanning window is controlled to be closed until the scanning stop time reaches a preset time interval, the first Bluetooth module is controlled to open the scanning window, and the broadcast information is scanned within the preset scanning time. When the first Bluetooth module scans the broadcast information within the preset scanning time, the first Bluetooth module is controlled to connect with the BLE physical key.

[0038] Figure 3It is a structural schematic diagram of the electronic device provided by this application. DETAILED DESCRIPTION

[0039] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application 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 can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0040] As mentioned in the background technology, the existing technology has the problem that the digital key on the vehicle side cannot use 100% of the time segment to scan the Bluetooth broadcast of the BLE physical key, which may lead to a slow connection establishment when the BLE physical key is close to the car, and may even cause the BLE physical key to still not take effect when the user reaches the door. Based on the above problems, the present application controls the first Bluetooth module of the digital key and the second Bluetooth module of at least one vehicle body anchor point to scan the broadcast information sent by the BLE physical key in a time-sharing manner within a preset scanning period, and then connects according to different situations, thereby ensuring that the broadcast information is effectively captured within the period when the BLE physical key sends the broadcast information, achieving the effect of fast connection, and ensuring that the BLE physical key takes effect in a timely manner. The present application is further described in detail below in conjunction with the embodiments.

[0041] Example 1

[0042] Figure 1 It is a flow chart of a digital key control method provided in this embodiment. The method can be executed by a digital key control device. The device can be composed of software and / or hardware and is generally integrated in an electronic device. The electronic device can be a body controller or a digital key controller. For ease of understanding, each step in the control method of this embodiment takes the digital key controller as the execution subject.

[0043] like Figure 1 As shown, this embodiment provides a digital key control method, which is applied to a vehicle end and includes the following steps:

[0044] S110, controlling the first Bluetooth module of the digital key and the second Bluetooth module of at least one vehicle body anchor point to scan the broadcast information sent by the BLE physical key in a time-sharing manner within a preset scanning period.

[0045] Among them, the "digital key" is a key integrated in the vehicle end, which can authorize wearable devices such as smartphones, NFC smart cards, smart watches, smart bracelets, or BLE physical keys to unlock the vehicle through communication technologies such as NFC, BLE or UWB. The first Bluetooth module contained in the digital key can realize sending broadcasts and scanning broadcasts. The "body anchor point" is a device arranged around the vehicle body for the vehicle end to obtain the electromagnetic wave field strength value of the BLE physical key positioning. The body anchor point can be 1, 2, 3 or 4, etc. The second Bluetooth module set on the body anchor point can scan and broadcast. "Time-sharing scanning" is time-sharing scanning, for example, the preset scanning cycle is divided into 5 time periods, the first Bluetooth module scans in the first time period, the second Bluetooth module of the second body anchor point scans in the second time period, the second Bluetooth module of the third body anchor point scans in the third time period, and the second Bluetooth module of the fourth body anchor point scans in the fourth time period. The "preset scanning period" can be set according to the BLE physical key broadcast period, as long as the BLE physical key broadcast period covers the preset scanning period, for example, it is equal to the BLE physical key broadcast period, or 1 / 2 or 1 / 5 of the BLE physical key broadcast period. The BLE physical key broadcast period is the period during which the BLE physical key sends broadcast information.

[0046] In an optional implementation, before controlling the first Bluetooth module of the digital key and the second Bluetooth module of at least one vehicle body anchor point to time-share scan the broadcast information sent by the BLE physical key within a preset scanning period, it also includes:

[0047] The preset scanning period is determined according to the BLE physical key broadcast period, the number of vehicle body anchor points, the first Bluetooth module scanning time of the digital key and the second Bluetooth module scanning time of the vehicle body anchor points.

[0048] This embodiment determines the preset scanning period based on the BLE physical key broadcast period, the number of vehicle body anchor points, the scanning time of the first Bluetooth module of the digital key and the scanning time of the second Bluetooth module of the vehicle body anchor point. The preset scanning period is more in line with actual use requirements. The BLE physical key broadcast period is the period for the BLE physical key to send broadcasts, such as 500ms. The number of vehicle body anchor points refers to the number of vehicle body anchor points used to scan the broadcast information sent by the BLE physical key, such as 2, 4, etc. If one or more anchor points of the vehicle body are not used to scan the broadcast information sent by the BLE physical key, they are not counted. The scanning time of the first Bluetooth module and the scanning time of the second Bluetooth module can be pre-configured or use the default scanning time of the Bluetooth module, such as 20ms or 30ms, etc., and can be the same or different. The scanning time can be as short as possible to reduce Bluetooth power consumption.

[0049] In some examples, if the BLE physical key broadcast cycle is 500ms, within 500ms, the BLE physical key can send a total of 3 broadcasts on 3 network channels (such as 37, 38, and 39 network channels, which are data signal transmission channels using wireless signals as transmission media) (the transmission time of each broadcast is approximately 0.6 to 1.2ms), the number of vehicle body anchor points is 4, the scanning time of the first Bluetooth module of the digital key is 20ms, and the scanning time of the second Bluetooth module of the vehicle body anchor point is 20ms, then the preset scanning cycle is 20+20*4=100ms, 100ms<500ms, which meets the scanning requirements. It can be seen that the BLE physical key broadcast cycle is mainly used to determine whether the preset scanning cycle is within its coverage range. If it is within the range, the preset scanning cycle can be used. If it is not within the range, it is necessary to adjust the scanning time of the two Bluetooth modules or adjust the number of vehicle body anchor points.

[0050] If the moment when each Bluetooth module opens the scanning window can be accurately controlled during the time-sharing scanning process, the interference of the results caused by repeated scanning can be reduced. Therefore, in an optional implementation of this embodiment, before the first Bluetooth module controlling the digital key and the second Bluetooth module of at least one vehicle body anchor point time-sharingly scan the broadcast information sent by the BLE physical key within the preset scanning period, it also includes: the first Bluetooth module controlling the digital key sends a synchronous timing broadcast message in the vehicle body anchor point network; the second Bluetooth module controlling at least one vehicle body anchor point receives the synchronous timing broadcast message and starts the timing synchronously. This implementation can achieve time synchronization between the first Bluetooth module and at least one second Bluetooth module. The vehicle body anchor point network includes CAN / LIN / Ethernet or other networks used for vehicle body communication.

[0051] In an optional implementation, controlling the first Bluetooth module of the digital key and the second Bluetooth module of at least one vehicle body anchor point to time-share scan the broadcast information sent by the BLE physical key within a preset scanning period includes:

[0052] Control the first Bluetooth module of the digital key to open a scanning window, scan the broadcast information sent by the BLE physical key within the scanning time of the first Bluetooth module, and close the scanning window;

[0053] The second Bluetooth module of at least one vehicle body anchor point is controlled to open a scanning window, scan broadcast information within the scanning time of the second Bluetooth module, and close the scanning window.

[0054] This implementation method realizes time-sharing scanning by controlling each Bluetooth module to open and close the scanning window, thereby improving the accuracy of time-sharing scanning and reducing resource waste.

[0055] Continuing with the above example, since there are 4 vehicle body anchor points, there are also 4 corresponding second Bluetooth modules. The first Bluetooth module opens the scanning window immediately after sending the synchronization timing message, and starts scanning the broadcast information sent by the BLE physical key. If the second Bluetooth module receives the synchronization timing broadcast message, the 4 second Bluetooth modules calculate the opening time of their respective scanning windows according to their respective numbers, T2=T1+anchor point number*t, where T2 is the opening time of a second Bluetooth module scanning window, T1 is the opening time of the first Bluetooth module scanning window, and t is the scanning time of the first Bluetooth module (equal to the scanning time of the second Bluetooth module). For example, if the opening time of the scanning window of the first Bluetooth module is 0, the opening time of the scanning window of the first second Bluetooth module is 20ms, the opening time of the scanning window of the second second Bluetooth module is 40ms, the opening time of the scanning window of the third second Bluetooth module is 60ms, and the opening time of the scanning window of the fourth second Bluetooth module is 80ms.

[0056] In an optional implementation, when the second Bluetooth module does not open the scanning window and does not have other tasks, the second Bluetooth module is controlled to sleep; when the second Bluetooth module does not open the scanning window and has other tasks, the second Bluetooth module is controlled to perform other tasks. This implementation can further reduce the energy consumption of the second Bluetooth module, and stop sleeping after opening the scanning window. Other tasks are tasks other than scanning the broadcast information sent by the BLE physical key.

[0057] S120: When the first Bluetooth module scans the broadcast information, control the first Bluetooth module to connect with the BLE physical key.

[0058] If the first Bluetooth module scans the broadcast information, the first Bluetooth module is controlled to connect with the BLE physical key, thereby achieving a one-time discovery and one-time connection effect.

[0059] S130. When at least one second Bluetooth module scans the broadcast information, control the closing of the scanning window until the scanning stop time reaches a preset time interval, control the first Bluetooth module to scan the broadcast information within the preset scanning time, and when the first Bluetooth module scans the broadcast information within the preset scanning time, control the first Bluetooth module to connect with the BLE physical key.

[0060] If the second Bluetooth module scans the broadcast information, it is necessary to close the scanning window, that is, during the closing period, the first Bluetooth module and the second Bluetooth module will no longer scan until the stop scanning time reaches the preset time interval. At this time, the BLE physical key will enter the next sending cycle. At this time, it is very likely to scan the broadcast information by controlling the first Bluetooth module within the preset scanning time. If it is scanned, the first Bluetooth module is controlled to connect with the BLE physical key, thereby achieving the effect of one scan and two connections. Since the preset scanning cycle and the preset time interval are not too long, a quick connection can be achieved. Among them, the preset time interval can be less than or equal to the BLE physical key broadcast cycle.

[0061] In an optional implementation, when at least one second Bluetooth module scans broadcast information, controlling to close the scanning window until the scanning stop time reaches a preset time interval, controlling the first Bluetooth module to scan the broadcast information within the preset scanning time, and when the first Bluetooth module scans the broadcast information within the preset scanning time, controlling the first Bluetooth module to connect to the BLE physical key, including:

[0062] When at least one second Bluetooth module scans the broadcast information, obtaining a notification message sent by the second Bluetooth module;

[0063] According to the notification message, the scanning window is controlled to be closed until the scanning stop time reaches the preset time interval, the first Bluetooth module is controlled to open the scanning window, and the broadcast information is scanned within the preset scanning time. When the first Bluetooth module scans the broadcast information within the preset scanning time, the first Bluetooth module is controlled to connect with the BLE physical key.

[0064] In this embodiment, when a second Bluetooth module scans broadcast information, the second Bluetooth module will automatically send a notification message (a notification message refers to a message used to inform the digital key that the Bluetooth module has scanned broadcast information, which can be sent in the form of a body message. The body message refers to a message sent through CAN / LIN / Ethernet or other communication network transmission methods, and the message content includes broadcast content, cycle, next broadcast time point and other information). Therefore, the notification message can be obtained, and then the scanning window can be closed according to the notification message until the scanning stop time reaches the preset time interval, and the first Bluetooth module is controlled to open the scanning window. This method realizes the accurate scanning of the broadcast information by the first Bluetooth module through the notification message and the control of closing or opening the scanning window, thereby improving the connection efficiency.

[0065] In an optional implementation, the preset scanning period is less than the BLE physical key broadcast period, the preset time interval is less than the BLE physical key broadcast period, and the preset scanning time is greater than the scanning time of the first Bluetooth module during time-sharing scanning. The preset scanning period in this implementation is less than the BLE physical key broadcast period, so that the BLE physical key broadcast period covers the preset scanning period to ensure that the broadcast information is scanned; the preset time interval is less than the BLE physical key broadcast period, so that the first Bluetooth module enters the scanning working state in advance to ensure that no broadcast information is missed; the preset scanning time is greater than the scanning time of the first Bluetooth module during time-sharing scanning to ensure that the broadcast information can be scanned.

[0066] In some examples, the preset scanning period is 100ms, the BLE physical key broadcast period is 500ms, the preset time interval is 480ms, and the preset scanning time is 50ms.

[0067] In an optional embodiment, the method further includes: when neither the first Bluetooth module nor the second Bluetooth module scans the broadcast information within the first preset scanning cycle, repeating the step of controlling the first Bluetooth module of the digital key and the second Bluetooth module of at least one vehicle body anchor point to scan the broadcast information sent by the BLE physical key in a time-sharing manner within the preset scanning cycle. If neither the first Bluetooth module nor the second Bluetooth module scans the broadcast information within the first preset scanning cycle, it means that there is no BLE physical key that can be connected to the vehicle side, or the BLE physical key has not entered the discoverable range, then the step S110 needs to be repeated in the subsequent preset scanning cycle so that the adapted BLE physical key can be promptly discovered and connected when it enters the discoverable range.

[0068] The above method first controls the first Bluetooth module and the second Bluetooth module to scan the broadcast information in a preset scanning cycle in time-sharing manner, and can distribute the scanning tasks that the first Bluetooth module cannot complete due to the execution of the broadcast sending task to the second Bluetooth module, so as to ensure that the broadcast information is discovered by the vehicle end at one time when it appears in the discoverable range, greatly improving the speed of discovering the BLE physical key. When the time-sharing scanning is performed in the preset scanning cycle, if the broadcast information is discovered by the first Bluetooth module, the first Bluetooth module is directly connected to the BLE physical key. If the broadcast information is discovered by the second Bluetooth module, the scanning is first controlled to stop, and when the stop scanning time reaches the preset time interval, the first Bluetooth module is controlled to scan the broadcast information within the preset scanning time. The broadcast information will definitely be scanned within the preset scanning time. When the broadcast information is discovered by the first Bluetooth module, the first Bluetooth module is connected to the BLE physical key. The method makes full use of the Bluetooth scanning function of the vehicle body anchor point through time-sharing multiplexing, and realizes that the first Bluetooth module establishes a connection with the BLE physical key when the BLE physical key sends the broadcast information for the first or second time within the discoverable range without affecting other tasks or functions of each Bluetooth module on the vehicle end, and the connection speed is fast, which improves the user experience.

[0072] A connection module 202, configured to control the first Bluetooth module to connect with the BLE physical key when the first Bluetooth module scans the broadcast information;

[0073] When at least one second Bluetooth module scans the broadcast information, the scanning window is controlled to be closed until the scanning stop time reaches a preset time interval, and the first Bluetooth module is controlled to scan the broadcast information within the preset scanning time. When the first Bluetooth module scans the broadcast information within the preset scanning time, the first Bluetooth module is controlled to connect with the BLE physical key.
