DETAILED DESCRIPTION

[0019] 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.

[0020] As mentioned in the background technology, the prior art has the problem of slow connection speed between the smart key and the vehicle end, and slow reconnection speed when disconnection occurs. In response to this, the present application improves the connection speed and connection success rate by reducing the broadcast interval and broadcast power of the key end after the vehicle end scans the broadcast information sent by the key end and after the key end receives the connection request sent by the vehicle end, and improves the reconnection speed by reducing the broadcast interval when disconnection occurs. The present application is further described in detail below in conjunction with the embodiments.

[0021] Example 1 Figure 1 This 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 smart key. Each step in the control method of this embodiment is executed by the smart key.

[0022] like Figure 1 As shown, this embodiment provides a digital key control method, comprising the following steps: S110, in response to the scan reply information sent by the vehicle-side Bluetooth module, control the key-side Bluetooth module to broadcast according to a first broadcast interval and a first broadcast power, wherein the first broadcast interval is smaller than an initial broadcast interval, and the first broadcast power is greater than an initial broadcast power.

[0023] The Bluetooth module on the key side will send broadcast information at a certain broadcast interval (i.e., the initial broadcast interval in this application) and broadcast power (i.e., the initial broadcast power in this application). When the Bluetooth module on the vehicle side scans the broadcast information, the vehicle side will automatically send a scan reply message (for example, in the form of a reply frame). When the key side receives the scan reply message, it controls the Bluetooth module on the key side to broadcast according to the first broadcast interval and the first broadcast power. The broadcast information is the same as the broadcast information at the initial broadcast interval and the initial broadcast power, but because the broadcast interval and the broadcast power have been reduced, it is more conducive to the vehicle-side Bluetooth module to scan the broadcast information faster.

[0024] In an optional implementation manner, the first broadcast interval is determined in the following manner: A first broadcast interval is determined according to the initial battery power, the current battery power, and the initial broadcast interval.

[0025] Among them, "Battery initial power" is the power of the battery when it is fully charged. "Battery current power" is the battery power when sending broadcast information at the current moment.

[0026] Optionally, the first broadcast interval interval conn The calculation is done using the following formula: ,in, is the initial battery power, V is the current battery power, and interval is the initial broadcast interval.

[0027] In an optional implementation manner, the first broadcast power is determined in the following manner: The first broadcast power is determined according to the preset increase ratio and the initial broadcast power.

[0028] The "preset increase ratio" refers to a preset ratio for increasing the initial broadcast power, which may be 1.5 or 2, for example.

[0029] Optionally, the first broadcast power conn Use the following formula to calculate: power conn =k1·power nomal , where k1 is the preset increase ratio, power nomal is the initial broadcast power.

[0030] S120, responding to the connection request sent by the vehicle-side Bluetooth module, controlling the key-side Bluetooth module to broadcast according to the first broadcast interval and the first broadcast power until connecting with the vehicle-side.

[0031] During the whole process from the scan reply message sent by the vehicle-side Bluetooth module to the successful connection between the key-side and the vehicle-side, the key-side Bluetooth module always broadcasts at the first broadcast interval and the first broadcast power to improve the connection speed. After the successful connection, the broadcast power can be restored to the initial broadcast power.

[0032] S130. In case of disconnection, control the key-end Bluetooth module to send broadcasts according to a second broadcast interval, where the second broadcast interval is smaller than the initial broadcast interval.

[0033] When the key is accidentally disconnected from the vehicle's Bluetooth, it is necessary to quickly reconnect to reduce the functional failure caused by the disconnection. At this time, the key broadcast interval needs to be adjusted to the second broadcast interval, and the broadcast power can still be the initial broadcast power. Because the owner is near the car at this time, to speed up the reconnection, just adjust the broadcast interval. If the broadcast power is increased, the connection will still be reestablished when the owner is too far away from the vehicle, which has no practical effect.

[0034] In an optional implementation manner, the second broadcast interval is determined in the following manner: The second broadcast interval is determined according to the number of disconnections, the preset shortening ratio and the initial broadcast interval.

[0035] Among them, "Number of disconnections" refers to the total number of disconnections between the vehicle and the key in this connection cycle. This connection cycle is the period from the successful connection between the vehicle and the key to the vehicle locking. "Preset shortening ratio" refers to the preset ratio of shortening the initial broadcast interval, for example, it can be 0.5 or 0.7.

[0036] Optionally, the second broadcast interval interval disconn Use the following formula to calculate: interval disconn =interval*k2* , k2 is the preset shortening ratio, and n is the number of disconnections. For example, when k2 is 0.5 and n is 1, interval disconn is 0.5interval, when k2 is 0.5 and n is 2, interval disconn The calculation method means that each time a connection is disconnected, the second broadcast interval is shortened by half of the previous broadcast interval.

[0037] The above-mentioned digital key control method is applied to the key end, including: responding to the scan reply information sent by the vehicle-end Bluetooth module, controlling the key-end Bluetooth module to broadcast according to the first broadcast interval and the first broadcast power, the first broadcast interval is less than the initial broadcast interval, and the first broadcast power is greater than the initial broadcast power; responding to the connection request sent by the vehicle-end Bluetooth module, controlling the key-end Bluetooth module to broadcast according to the first broadcast interval and the first broadcast power until it is connected to the vehicle end; in the case of disconnection, controlling the key-end Bluetooth module to broadcast according to the second broadcast interval, the second broadcast interval is less than the initial broadcast interval. After the vehicle-end Bluetooth module scans the broadcast information of the key end and receives the connection request, this method realizes the rapid connection between the smart key and the vehicle end and improves the connection success rate by reducing the broadcast interval and the broadcast power. When the two are disconnected, the method also realizes rapid reconnection by reducing the broadcast interval.

[0038] Example 2 Figure 2 It is a flowchart 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. Each step in the control method of this embodiment is executed by the digital key controller.

[0039] like Figure 2 As shown, this embodiment provides a digital key control method, which is applied to a vehicle end and includes: S210 , in response to scanning the broadcast sent by the BLE physical key, sending a scan reply message and a connection request.

[0040] S220: In case of a connection failure, resend the connection request until the connection is successful or the total number of connection requests sent meets a preset total number of times.

[0041] In this embodiment, when the connection fails, the connection request needs to be resent, and there is no need to rescan the broadcast sent by the key, thereby shortening the connection time.

[0042] In an optional implementation manner, the preset total number of times is determined in the following manner: The preset total number of times is determined according to the initial value of the number of connection requests sent, the number of successful connection establishments, the number of failed connection establishments, and the minimum number of connection requests sent.

[0043] Among them, "Initial value of the number of times the connection request is sent" refers to the initial value of the number of times the vehicle is allowed to send connection requests during the current connection cycle, for example, 2 or 3. "Number of successful connections" refers to the total number of successful connections between the vehicle and the key. "Number of failed connections" refers to the total number of failed connections between the vehicle and the key. "Minimum value of the number of times the connection request is sent" refers to the minimum number of times the vehicle is allowed to send connection requests, which can be the same as the initial value of the number of times the connection request is sent, for example, 2 or 3.

[0044] Optionally, the preset total number N is calculated using the following formula: N=N1+m N -floor(m Y / 10) and N≧N2, where N1 is the initial number of connection requests sent, N2 is the minimum number of connection requests sent, and m N The number of failed connection establishments, m Y is the number of successful connections. floor() represents the rounding function. For example, when m Y When / 10 is 0.3, floor(m Y / 10) is 0, when m Y When / 10 is 1.3, floor(m Y / 10) is 1. This calculation method means that every time a connection fails to be established, the preset total number of times is increased by 1 based on the initial value of the number of connection requests sent, and every 10 successful connections are established, the preset total number of times is reduced by 1 based on the initial value of the number of connection requests sent, but it must be greater than or equal to the minimum number of connection requests sent.

[0045] S230: When the connection fails after the total number of connection requests is sent meets the preset total number, the vehicle-side Bluetooth module is controlled to rescan the broadcast sent by the BLE physical key.

[0046] If the total number of connection requests sent meets the preset total number and the connection still fails, it means that the key is far away from the vehicle and needs to be scanned again.

[0047] S240: In case of disconnection, control the vehicle-side Bluetooth module to rescan the broadcast sent by the BLE physical key.

[0048] The above-mentioned digital key control method is applied to the vehicle side, including: responding to scanning the broadcast sent by the BLE physical key, sending a scan reply message and a connection request; in the case of connection failure, resending the connection request until the connection is successful or the total number of connection requests sent meets the preset total number; in the case of connection failure after the total number of connection requests sent meets the preset total number, the vehicle-side Bluetooth module is controlled to rescan the broadcast sent by the BLE physical key; in the case of disconnection, the vehicle-side Bluetooth module is controlled to rescan the broadcast sent by the BLE physical key. This method corresponds to the control method applied to the key side, so it has at least the same technical effect, and this method also achieves fast connection by resending the connection request when the connection fails, without rescanning the key-side broadcast, which further speeds up the connection speed.

[0049] Example 3 like Figure 3 As shown, this embodiment provides a digital key control device, which is applied to a key end, and includes: The broadcast sending module 301 is used to respond to the scan reply information sent by the vehicle-side Bluetooth module, and control the key-side Bluetooth module to send a broadcast according to a first broadcast interval and a first broadcast power, wherein the first broadcast interval is smaller than the initial broadcast interval, and the first broadcast power is larger than the initial broadcast power; The connection module 302 is used to respond to the connection request sent by the vehicle-side Bluetooth module, and control the key-side Bluetooth module to broadcast according to the first broadcast interval and the first broadcast power until it is connected with the vehicle-side; The reconnection module 303 is used to control the key-end Bluetooth module to send a broadcast according to a second broadcast interval when the connection is disconnected, and the second broadcast interval is smaller than the initial broadcast interval.
