[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting to the scope of the application or its applications or uses.

[0035] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, the techniques, methods, and devices should be construed as being a part of the specification to the extent that the same are pertinent to the disclosure.

[0036] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Thus, other examples of the example embodiments can have different values.

[0037] As shown in Figure 1 and Figure 2 The embodiment of the present application provides a key welcome unlocking control method based on a vehicle position, and the method comprises the following steps:

[0038] Step S1, a specific position area is started to close a key welcome unlocking function, and a unlocking key is set; specifically, the key welcome unlocking function is closed, that means, on a mobile phone app or a central control large screen corresponding to the vehicle, the key welcome unlocking function in the specific position area is closed.

[0039] It should be noted that the function of starting the key welcome unlocking in the specific position area needs to be set, and the mobile phone app or the central control large screen has options of starting and closing.

[0040] When the key welcome unlocking function is not closed, the key responds to a conventional welcome unlocking strategy.

[0041] Step S2, a first position area which does not respond to the welcome unlocking and a second position area which responds to the conventional welcome unlocking strategy are set;

[0042] Step S3, a position of the unlocking key is acquired;

[0043] Step S4, based on the position of the unlocking key, it is judged whether the unlocking key is in the first position area, if yes, step S5 is executed;

[0044] Step S5, a stay time of the unlocking key in the first position area is acquired;

[0045] Step S6, based on the stay time, it is judged whether the stay time is less than a preset time, if yes, the welcome unlocking is not triggered.

[0046] The application opens the specific position area first, sets the key unlocking function, and then sets the first position area which does not respond to the welcome unlocking and the second position area which responds to the conventional welcome unlocking strategy, then acquires the position of the unlocking key, and judges whether the unlocking key is in the first position area based on the position of the unlocking key, if yes, acquires the residence time of the unlocking key in the first position area, and judges whether the residence time is less than the preset time based on the residence time, if yes, the welcome unlocking is not triggered. The application sets the first position area which does not respond to the welcome unlocking and the second position area which responds to the conventional welcome unlocking strategy, and real-time locates the position of the unlocking key, when the unlocking key is in the first position area and the time in the first position area is less than the preset time, the welcome unlocking is not opened, and the purpose of preventing the frequent false triggering of the welcome unlocking is achieved.

[0047] In an embodiment of the key welcome unlocking control method based on the vehicle position, the unlocking key includes a traditional remote key, a digital key, a smart key, or any combination thereof.

[0048] Specifically, the digital key includes a UWB key, and the smart key includes an RKE key, a BLE key of a mobile phone / bracelet Bluetooth.

[0049] The RKE key is composed of a vehicle-mounted anti-theft host and an electronic key. The smart key mainly realizes the remote control and unlocking function of the vehicle through low-power Bluetooth, and can control the vehicle door through the mobile phone, bracelet and Bluetooth connection.

[0050] It should be noted that the unlocking key can be selected multiple times, including but not limited to a traditional RKE key, a BLE key of a mobile phone / bracelet Bluetooth, a UWB key, etc. It should be noted that only the keys supported by the vehicle and owned by the vehicle owner can be selected.

[0051] In an embodiment of the key welcome unlocking control method based on the vehicle position, the second position area and the first position area refer to the positions defined by the mobile phone or the vehicle central control large screen.

[0052] Specifically, the vehicle position information navigation interface of the mobile phone app or the central control large screen can be defined by zooming in on the interface to finely draw the first position area which does not respond to the welcome unlocking and the second position area which responds to the conventional welcome unlocking strategy.

[0053] In an embodiment of the key welcome unlocking control method based on the vehicle position, in step S6, if it is judged that the unlocking key is in the second position area, the conventional welcome unlocking strategy is responded to. In this way, the situation of frequent false triggering of the welcome unlocking is avoided.

[0054] In an embodiment of the vehicle location-based key welcome unlocking control method of the present application, in step S6, if the stay time is greater than the preset time, the welcome unlocking strategy is triggered, further avoiding frequent false triggering of the welcome unlocking.

[0055] Further, the preset time can be set to 3 seconds, that is, the key is considered to be valid to unlock the door when it stays near the vehicle for more than 3 seconds. When the selected key stays near the vehicle for less than the preset time, the vehicle identifies the key as invalid and does not trigger the welcome unlocking request.

[0056] In an embodiment of the vehicle location-based key welcome unlocking control method of the present application, after step S2, the following steps are further included: obtaining key information, determining whether the key is an unlocking key, if yes, executing step S3, and if no, responding to the regular welcome unlocking strategy.

[0057] Regardless of the above steps operated in the mobile phone app, the vehicle central control large screen, or other vehicle control terminal, when all settings are completed and the OK button is clicked, all terminals logged in by the same user are synchronized with the above information to prevent the information from being out of synchronization when different keys are switched. It should be noted that the key of the other user is not synchronized by the vehicle owner to achieve the personalized user experience of thousands of people.

[0058] After the above steps are set, when the unlocking key stays near the vehicle for less than the preset time, the body domain controller identifies the unlocking key as invalid and does not trigger the welcome unlocking, that is, the door is not unlocked.

[0059] When the unlocking key stays near the vehicle for more than the preset time, the body domain controller identifies the key as valid and triggers the welcome unlocking, that is, the door is unlocked.

[0060] When the non-unlocking key approaches the vehicle, the body domain controller identifies the key as valid and triggers the welcome unlocking, that is, the door is unlocked.

[0061] When the vehicle drives away from the designated area or the user turns off the function, when all keys approach the vehicle, the body domain controller identifies the key as valid and responds to the regular welcome unlocking strategy.

[0062] According to the second aspect of the present application, as shown in Figure 3 A vehicle location-based key welcome unlocking control system is provided, which includes a body domain controller, an intelligent key, a vehicle positioning system, a door lock system, and a central control system.

[0063] The body domain controller is electrically connected with the door lock control system and the central control system, respectively, and is used to control the opening or closing of the door lock system.

[0064] The smart key is wirelessly connected with the vehicle positioning system and the central control system.

[0065] The vehicle positioning system is used to locate the positions of the smart key and the vehicle, and is electrically connected with the central control system.

[0066] The first position area on the central control system is set not to respond to the welcome unlocking, and the second position area is set to respond to the regular welcome unlocking strategy, when the smart key is located in the first position area for less than a preset time, the vehicle positioning system sends a signal to the vehicle body area controller, and the vehicle body area controller controls the door lock system not to be unlocked.

[0067] When the smart key is not located in the first position area, or is located in the first position area for less than a preset time, the vehicle positioning system does not send any signal, and the door is not unlocked.

[0068] In an embodiment of the key welcome unlocking control system based on the vehicle position of the application, the preset time is 3 seconds.

[0069] It should be noted that the preset time is set to 3 seconds here, which is only illustrative, and by no means limits the application and its application or use, and can be set according to the actual situation.

[0070] The application sets the first position area not to respond to the welcome unlocking, and the second position area to respond to the regular welcome unlocking strategy, and real-time locates the position of the unlocking key, when the unlocking key is in the first position area, and the time in the first position area is greater than the preset time, the welcome unlocking is started, which can prevent frequent false triggering of the vehicle welcome unlocking, improve the user welcome experience, and reduce the battery power supply.

[0071] Although some specific embodiments of the application have been described in detail above, those skilled in the art should understand that the above examples are only for illustration, and are not intended to limit the scope of the application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the application. The scope of the application is defined by the appended claims.
