Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A two-way WiFi implementation method of a vehicle, an in-vehicle infotainment system, and a storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
FIG. 1 is a flow diagram of a method for two-way WiFi implementation for a vehicle in accordance with one embodiment of the present invention. It should be noted that the vehicle two-way WiFi implementation method of the embodiment of the present invention is applicable to the vehicle-mounted infotainment system of the embodiment of the present invention, and it should be noted that the vehicle includes a vehicle-mounted infotainment system and a vehicle-mounted rear seat infotainment system, where the vehicle-mounted infotainment system has a first wireless WiFi module supporting an AP mode and an STA mode, and supports switching between the two modes.
As shown in fig. 1, the two-way WiFi implementation method of the vehicle may include:
s110, when the first wireless WiFi module works in the AP mode, the vehicle-mounted information entertainment system sends an interconnection connection request to a second wireless WiFi module of the vehicle-mounted rear seat entertainment system, so that the second wireless WiFi module establishes an interconnection local area network with the vehicle-mounted information entertainment system as a hot spot based on the interconnection connection request.
In the embodiment of the invention, after a vehicle is started, when the vehicle-mounted infotainment system detects that the first wireless WiFi module works in the AP mode, the vehicle-mounted infotainment system sends an interconnection connection request to the second wireless WiFi module of the vehicle-mounted rear seat infotainment system, so that the second wireless WiFi module receives the interconnection connection request and establishes an interconnection local area network with the vehicle-mounted infotainment system as a hotspot based on the interconnection connection request.
For example, as shown in fig. 2, assuming that the in-vehicle infotainment system IVI is located at the center console in the vehicle, RSE L and RSE R are two in-vehicle rear seat infotainment systems, wherein RSE L is located at the back of the driver's seat and RSE R is located at the back of the passenger's seat for entertaining rear seat personnel. When detecting that the vehicle-mounted information entertainment system IVI works in the AP mode, the vehicle-mounted information entertainment system IVI sends an interconnection connection request to a second wireless WiFi module of the vehicle-mounted rear seat entertainment system, and the PSE L and the PSE R establish an interconnection local area network taking the vehicle-mounted information entertainment system IVI as a hot spot based on the interconnection connection request, so that the vehicle-mounted information entertainment system IVI provides the hot spot to the PSE L and the PSE R.
And S120, when the vehicle-mounted information entertainment system determines that the external hot spot needs to be connected to acquire the network, determining a target external hot spot to be connected, and acquiring network configuration information of the target external hot spot.
The external hot spot includes, but is not limited to, a hot spot provided by a mobile terminal, for example, the mobile terminal may be a smart phone or a tablet computer.
It should be noted that the step of determining that an external hotspot needs to be connected to acquire a network by the in-vehicle infotainment system can be implemented by the following two ways:
as an example, the specific implementation process for determining that the in-vehicle infotainment system needs to connect to the external hotspot to acquire the network can be as follows: the vehicle-mounted information entertainment system can provide a network connection configuration interface for a user, wherein the network connection configuration interface is provided with a first trigger control for network connection, the first trigger control for network connection is used for indicating the first wireless WiFi module to be switched from the AP mode to the STA mode, and when receiving trigger operation of the user for the trigger control, the vehicle-mounted information entertainment system determines that the vehicle-mounted information entertainment system needs to be connected with an external hotspot to acquire a network.
For example, as shown in fig. 3, after an internet local area network with a vehicle infotainment system IVI as a hotspot is established, the vehicle infotainment system IVI may provide a network connection configuration interface to a user, where the network connection configuration interface has a first trigger control for network connection, and the user may select "network connection" in the network connection configuration interface through the first trigger control; when the vehicle-mounted infotainment system IVI receives the triggering operation of the triggering control, it can be determined that the vehicle-mounted infotainment system needs to be connected with an external hotspot to acquire a network.
It should be further noted that, as shown in fig. 3, the network connection configuration interface further has a second trigger control for the internet connection, where the second trigger control is used to instruct the first wireless WiFi module to switch from the STA mode to the AP mode, and establish an internet local area network with the in-vehicle infotainment system as a hot spot.
As another example, a specific implementation of determining that an in-vehicle infotainment system needs to connect to an external hotspot to acquire a network may be as follows: the vehicle-mounted infotainment system determines the residual flow of a mobile data network of the vehicle-mounted infotainment system, and determines that an external hotspot needs to be connected to acquire the network when the residual flow is less than or equal to a preset threshold value.
For example, the vehicle-mounted infotainment system IVI may automatically detect and determine a remaining traffic of the mobile data network in its own system, and when the remaining traffic is less than or equal to a preset threshold, it may be determined that the vehicle-mounted infotainment system needs to connect to an external hotspot to acquire the network, so as to avoid over-consuming the mobile data network of the IVI.
In the embodiment of the invention, when it is determined that the vehicle-mounted infotainment system needs to connect with the external hotspot to acquire the network, a target external hotspot to be connected needs to be determined, for example, an external hotspot WiFi list can be provided for a user, wherein the external hotspot WiFi list comprises at least one external hotspot, then, the selection operation of the user for the at least one external hotspot is received, and the external hotspot selected by the user is determined as the target external hotspot to be connected.
For example, when it is determined that an external hotspot needs to be connected to acquire a network, the vehicle-mounted infotainment system may send a WiFi list synchronization request to an operating system of the vehicle-mounted infotainment system, so that the operating system returns an external hotspot WiFi list in system settings based on the WiFi list synchronization request, then receives the external hotspot WiFi list in the system settings returned by the operating system, and provides the external hotspot WiFi list to a user, and the user performs an external hotspot selection operation, and then the vehicle-mounted infotainment system receives a selection operation of the user for at least one external hotspot, determines the external hotspot selected by the user as a target external hotspot to be connected, and acquires network configuration information of the target external hotspot, where the network configuration information includes but is not limited to WiFi, a password, and other information.
S130, the vehicle-mounted information entertainment system sends the network configuration information to a second wireless WiFi module of the vehicle-mounted rear seat entertainment system based on the internet local area network, so that the second wireless WiFi module is accessed to a target external hotspot according to the network configuration information.
In the embodiment of the invention, based on the interconnected local area network when the vehicle-mounted information entertainment system works in the AP mode, the vehicle-mounted information entertainment system sends the network configuration information of the accessed target external hotspot to the second wireless WiFi module, and when the second wireless WiFi module in the vehicle-mounted rear seat entertainment system receives the network configuration information, the second wireless WiFi module feeds back the feedback information to the vehicle-mounted information entertainment system so as to inform the second wireless WiFi module that the network configuration information is received. When the vehicle-mounted information entertainment system receives the feedback information, the vehicle-mounted information entertainment system automatically disconnects the interconnected local area network when the vehicle-mounted information entertainment system works in the AP mode, so that the second wireless WiFi module can be accessed to a target external hotspot according to network configuration information.
And S140, the vehicle-mounted information entertainment system switches the working mode of the first wireless WiFi module from the AP mode to the STA mode, and accesses the target external hotspot according to the network configuration information in the STA mode.
In the embodiment of the invention, the second wireless WiFi module of the vehicle-mounted backseat entertainment system is successfully accessed to the target external hotspot, the vehicle-mounted infotainment system switches the working mode of the first wireless WiFi module from the AP mode to the STA mode, and the vehicle-mounted infotainment system is accessed to the target external hotspot according to the network configuration information in the STA mode.
It should be noted that, the external hotspot provides a network for the in-vehicle device on one hand, and establishes the WiFi local area interconnection function and has a network management function at the same time on the other hand.
For example, as shown in fig. 4, the internet with the vehicle infotainment system IVI hotspot as the center is changed to the internet with the smartphone WiFi hotspot as the center, that is, the smartphone is in AP mode, and the vehicle infotainment system IVI, PSE L, and PSE R are in STA mode.
According to the vehicle two-way WiFi implementation method of the embodiment of the invention, when the first wireless WiFi module works in the AP mode through the vehicle-mounted information entertainment system, an interconnection connection request can be sent to the second wireless WiFi module of the vehicle-mounted backseat entertainment system, so that the second wireless WiFi module establishes an interconnection local area network with the vehicle-mounted information entertainment system as a hot spot based on the interconnection connection request, then when the external hot spot is determined to be connected to obtain the network, a target external hot spot to be connected is determined, the network configuration information of the target external hot spot is obtained, then the network configuration information is sent to the second wireless WiFi module of the vehicle-mounted backseat entertainment system based on the interconnection local area network, so that the second wireless WiFi module is accessed to the target external hot spot according to the network configuration information, then the working mode of the first wireless WiFi module is switched from the AP mode to the STA mode, and in the STA mode, and accessing the target external hotspot according to the network configuration information. According to the method, the AP mode of the vehicle-mounted information entertainment system is automatically switched into the STA mode, and the external hotspot and the password which need to be connected are informed to the vehicle-mounted rear seat entertainment system in the interconnection environment before the mode switching, so that the vehicle-mounted rear seat entertainment system and the vehicle-mounted information entertainment system are automatically connected with the external hotspot, the double-path WiFi function of the vehicle-mounted information entertainment system is realized, redundant WiFi modules do not need to be carried on hardware of the vehicle-mounted information entertainment system in the whole process, and the material cost, the test cost and the production cost of a product are reduced.
FIG. 5 is a flow diagram of a method for two-way WiFi implementation for a vehicle in accordance with one embodiment of the present invention. As shown in fig. 3 and 5, the two-way WiFi implementation method of the vehicle may include:
s510, when the first wireless WiFi module works in the AP mode, the vehicle-mounted information entertainment system sends an interconnection connection request to a second wireless WiFi module of the vehicle-mounted rear seat entertainment system, so that the second wireless WiFi module establishes an interconnection local area network with the vehicle-mounted information entertainment system as a hot spot based on the interconnection connection request.
For example, as shown in fig. 2, assuming that the in-vehicle infotainment system IVI is located at the center console in the vehicle, RSE L and RSE R are two in-vehicle rear seat infotainment systems, wherein RSE L is located at the back of the driver's seat and RSE R is located at the back of the passenger's seat for entertaining rear seat personnel. When detecting that the vehicle-mounted information entertainment system IVI works in the AP mode, the vehicle-mounted information entertainment system IVI sends an interconnection connection request to a second wireless WiFi module of the vehicle-mounted rear seat entertainment system, and the PSE L and the PSE R establish an interconnection local area network taking the vehicle-mounted information entertainment system IVI as a hot spot based on the interconnection connection request, so that the vehicle-mounted information entertainment system IVI provides the hot spot to the PSE L and the PSE R.
S520, the vehicle-mounted infotainment system determines the residual flow of the mobile data network of the vehicle-mounted infotainment system.
For example, after establishing an internet lan with the in-vehicle infotainment system IVI as a hotspot, the in-vehicle infotainment system IVI may automatically detect and determine the remaining traffic of the mobile data network in its own system.
S530, when the residual flow is smaller than or equal to the preset threshold, it is determined that an external hotspot needs to be connected to acquire the network.
That is to say, the vehicle-mounted infotainment system IVI may automatically detect and determine the remaining traffic of the mobile data network in its own system, and when the remaining traffic is less than or equal to the preset threshold, it may be determined that the vehicle-mounted infotainment system needs to connect to an external hotspot to acquire the network, so as to avoid over-consuming the mobile data network of the IVI.
The external hot spot includes, but is not limited to, a hot spot provided by a mobile terminal, for example, the mobile terminal may be a smart phone or a tablet computer.
And S540, sending a WiFi list synchronization request to an operating system of the vehicle-mounted infotainment system, so that the operating system returns an external hot spot WiFi list in the system setting based on the WiFi list synchronization request.
In the embodiment of the invention, when the vehicle-mounted infotainment system determines that an external hotspot needs to be connected to acquire a network, the vehicle-mounted infotainment system can send a WiFi list synchronization request to an operating system of the vehicle-mounted infotainment system, so that the operating system returns an external hotspot WiFi list in the system setting based on the WiFi list synchronization request.
It should be noted that, when the WiFi list of the operating system of the in-vehicle infotainment system is updated, the external hotspot automatically synchronizes the WiFi list.
And S550, receiving an external hot spot WiFi list in the system setting returned by the operating system, and providing the external hot spot WiFi list for the user.
In the embodiment of the invention, the vehicle-mounted infotainment system receives the external hot spot WiFi list in the system setting returned by the operating system, provides the external hot spot WiFi list for the user, and the user can select the WiFi list based on the network connection configuration interface in the vehicle-mounted infotainment system. For example, as shown in the schematic diagram of fig. 3, a user may click "network connection" through a network connection configuration interface, then click "wifi name 1" connected, then click the edit of "wifi name 1", and then execute information such as password input of "wifi name 1" so that the in-vehicle infotainment system IVI is connected with "wifi name 1".
When the connection between the vehicle-mounted information entertainment system IVI and the WiFi name 1 fails, for example, the password input of the WiFi name 1 is wrong, the vehicle-mounted information entertainment system IVI can reselect an external hotspot in the WiFi list, or after the correct password is modified, the vehicle-mounted information entertainment system IVI is connected with the WIFI hotspot again.
And S560, receiving a selection operation of the user for at least one external hotspot, determining the external hotspot selected by the user as a target external hotspot to be connected, and acquiring network configuration information of the target external hotspot.
For example, the vehicle-mounted information entertainment system IVI receives a WiFi name 1 operation selected by a user and is successfully connected with the WiFi name 1, the vehicle-mounted information entertainment system IVI determines a smartphone with the WiFi name 1 as a target external hotspot to be connected, and obtains network configuration information of the target external hotspot, such as a WiFi name and a password.
S570, sending the network configuration information to a second wireless WiFi module of the vehicle-mounted rear seat entertainment system based on the internet local area network, so that the second wireless WiFi module can access the target external hot spot according to the network configuration information.
In the embodiment of the invention, based on the interconnected local area network when the vehicle-mounted information entertainment system works in the AP mode, the vehicle-mounted information entertainment system sends the network configuration information of the accessed target external hotspot to the second wireless WiFi module, and when the second wireless WiFi module in the vehicle-mounted rear seat entertainment system receives the network configuration information, the second wireless WiFi module feeds back the feedback information to the vehicle-mounted information entertainment system so as to inform the second wireless WiFi module that the network configuration information is received. When the vehicle-mounted information entertainment system receives the feedback information, the vehicle-mounted information entertainment system automatically disconnects the interconnected local area network when the vehicle-mounted information entertainment system works in the AP mode, so that the second wireless WiFi module can be accessed to a target external hotspot according to network configuration information.
And S580, the vehicle-mounted information entertainment system switches the working mode of the first wireless WiFi module from the AP mode to the STA mode, and accesses the target external hotspot according to the network configuration information in the STA mode.
For example, as shown in fig. 4, the internet with the vehicle infotainment system IVI hotspot as the center is changed to the internet with the smartphone WiFi hotspot as the center, that is, the smartphone is in AP mode, and the vehicle infotainment system IVI, PSE L, and PSE R are in STA mode.
S590, when the vehicle-mounted infotainment system does not successfully access the target external hotspot, the operating mode of the first wireless WiFi module may be switched from the STA mode to the AP mode, and the step of sending the interconnection connection request to the second wireless WiFi module of the vehicle-mounted rear seat infotainment system when the vehicle-mounted infotainment system operates in the AP mode is executed again, that is, the step of executing step S510 is executed again.
According to the vehicle two-way WiFi implementation method, the vehicle-mounted information entertainment system is automatically switched from the AP mode to the STA mode, and the vehicle-mounted rear seat entertainment system is informed of the external hot spot and the password which need to be connected in the interconnection environment before the mode switching, so that the vehicle-mounted rear seat entertainment system and the vehicle-mounted information entertainment system are automatically connected with the external hot spot, the two-way WiFi function of the vehicle-mounted information entertainment system is achieved, redundant WiFi modules do not need to be carried on hardware of the vehicle-mounted information entertainment system in the whole process, and material cost, test cost and production cost of products are reduced. And when the WiFi list of the operating system in the vehicle-mounted information entertainment system is updated, the WiFi list is automatically synchronized by external hotspots, so that the product experience is optimized.
