Description

Technical Field

[0001] The present application belongs to the field of communication technology, and in particular, relates to a network connection mode switching method and a terminal device. Background Art

[0002] The vehicle's in-vehicle infotainment system and in-vehicle devices support access point mode (AP) and station mode (STA), and support switching between the two modes. Users can actively switch to the desired working mode according to different usage requirements. For example, the in-vehicle device can be operated in access point mode and connected to the in-vehicle infotainment system operating in station mode. However, in this working mode, the in-vehicle infotainment system cannot be connected to other network devices at the same time, such as smartphones or other peripherals. This situation not only limits the user's ability to handle multiple tasks at the same time, but also affects the efficiency of information acquisition. Therefore, users need to switch modes in time so that the in-vehicle infotainment system can connect to other network devices.

[0003] The existing network connection mode switching mostly relies on the physical buttons of the device itself or dedicated mobile applications. This switching mechanism requires manual operation by the user, which is significantly inconvenient in practical applications, especially in the use scenarios of in-vehicle products. For users who pursue operational continuity and convenience, frequent manual adjustments to network settings are cumbersome.

[0048] The embodiment of the present application provides a network connection mode switching method, which is applied to an in-vehicle infotainment system and can be executed by a processor of a terminal device when running a computer program with corresponding functions, by confirming the operation mode of the in-vehicle device; when the in-vehicle device is running in access point mode, running in site mode and sending a connection request signal to the in-vehicle device; if the connection is successful, sending a mode switching request signal to the in-vehicle device; receiving a confirmation signal sent by the in-vehicle device; sending the network name and password of the in-vehicle infotainment system to the in-vehicle device; switching to access point mode, and establishing a connection with the in-vehicle device in response to the connection request signal of the in-vehicle device, wherein the in-vehicle device is used to switch to site mode, and send a connection request signal to the in-vehicle infotainment system based on the network name and password of the in-vehicle infotainment system. The automatic switching of the network connection mode can be realized, making the switching of the network connection mode more convenient and ensuring driving safety.

[0049] like Figure 1 As shown, the network connection mode switching method provided in the embodiment of the present application includes the following steps S101 to S106:

[0050] Step S101: confirm the operation mode of the vehicle-mounted device.

[0051] In the application, when the vehicle-mounted device is powered on, it performs a self-test of the operating mode to identify whether the current working state of the vehicle-mounted device is access point mode (AP) or station mode (STA). This step ensures that subsequent operations can be performed based on the correct prerequisites.

[0052] Step S102: When the vehicle-mounted device operates in the access point mode, the device operates in the station mode and sends a connection request signal to the vehicle-mounted device.

[0053] In the application, when it is determined that the vehicle-mounted device is in the access point mode, the vehicle-mounted infotainment system operates in the station mode. At this time, the vehicle-mounted infotainment system sends a connection request signal to the vehicle-mounted device to try to establish a connection with the vehicle-mounted device.

[0054] Step S103: If the connection is successful, a mode switching request signal is sent to the vehicle-mounted device.

[0055] In the application, if the in-vehicle infotainment system successfully connects to the in-vehicle device as an access point, it will send a mode switching request to the in-vehicle device, indicating that it is ready to change the working mode. This step is used to make the in-vehicle infotainment system actively switch to the access point mode, so that it can connect with more network devices. The entire switching process is automatically performed by the in-vehicle infotainment system, and the entire switching process is automated without manual intervention.

[0056] In an application, the mode switching request signal may include preset switching time information, which is used to agree with the vehicle-mounted device to perform mode switching simultaneously when the preset switching time is reached.

[0057] Step S104: receiving a confirmation signal sent by the vehicle-mounted device.

[0058] In the application, after receiving the mode switching request, the vehicle device will send back a confirmation signal to indicate that it is ready for mode switching. This two-way confirmation process ensures that both parties are ready for the next data exchange.

[0059] Step S105: Send the network name and password of the in-vehicle infotainment system to the in-vehicle device.

[0060] In the application, in order to achieve seamless switching, the in-vehicle infotainment system will then share its Wi-Fi network name (SSID) and password with the in-vehicle device, so that the in-vehicle device can quickly locate and connect to the in-vehicle infotainment system under the new network configuration.

[0061] Step S106, switching to access point mode, and establishing a connection with the vehicle-mounted device in response to a connection request signal from the vehicle-mounted device, wherein the vehicle-mounted device is used to switch to site mode and send a connection request signal to the vehicle-mounted infotainment system based on the network name and password of the vehicle-mounted infotainment system.

[0062] In the application, the in-vehicle infotainment system is converted to access point mode, and the in-vehicle device is converted to station mode accordingly. Subsequently, the in-vehicle device uses the previously acquired network information to try to reconnect to the in-vehicle infotainment system. When the connection request signal of the in-vehicle device is sent to the in-vehicle infotainment system, the in-vehicle infotainment system responds to the connection request signal, and the two are connected. This step enhances the flexibility of the system and can achieve seamless switching of modes, ensuring a good user experience.

[0063] The embodiment of the present application realizes the automatic switching of the network connection mode between the vehicle-mounted device and the vehicle-mounted infotainment system through the above method. This method significantly improves the convenience of use, reduces the trouble caused by manual adjustment of settings, and also ensures safety during driving, avoiding safety hazards caused by distracted operation. And the vehicle-mounted infotainment system is operated in access point mode as much as possible, so that it can be connected to more network devices, ensuring the efficiency of information acquisition and the ability of users to handle multiple tasks at the same time.

[0064] In one embodiment, step S106 specifically includes:

[0065] Switching to the access point mode at a preset switching time, and establishing a connection with the vehicle-mounted device in response to a connection request signal from the vehicle-mounted device;

[0066] Among them, the mode switching request signal includes a preset switching time, and the vehicle-mounted device is used to switch to the site mode at the preset switching time, and send a connection request signal to the vehicle-mounted infotainment system based on the network name and password of the vehicle-mounted infotainment system.

[0067] In the application, assume that the in-vehicle infotainment system and the dashcam are currently in station mode and access point mode respectively. At a certain moment, such as 5 minutes after the vehicle is started, the in-vehicle infotainment system will switch to access point mode according to the preset time. At the same time, it will send a mode switching request signal containing the preset time to the dashcam. After receiving this signal, the dashcam will automatically switch to station mode at the same preset time and try to connect using the network name and password previously obtained from the in-vehicle infotainment system.

[0068] For example, when the driver starts the vehicle, the in-vehicle infotainment system may be set to switch modes after 5 minutes. During these 5 minutes, the system will complete the initial connection, authentication, and necessary data exchange with the dashcam. After the preset time, the in-vehicle infotainment system will change to access point mode, while the dashcam will change to station mode and immediately start looking for and connecting to the new network environment. This time-synchronized switching mechanism ensures that both devices can complete the role conversion at almost the same time, thus avoiding connection failures or delays caused by asynchrony.

[0069] The method provided in the embodiment of the present application is highly automated and synchronized. First, by presetting the switching time, the entire process can be fully automated without manual user intervention, which greatly simplifies the operation process and improves the user experience. Secondly, synchronous switching reduces connection errors caused by mode mismatch and improves the reliability and stability of the system. In addition, this mechanism also allows for more flexible network configuration strategies, and the switching time can be adjusted according to different usage scenarios and requirements to achieve the best effect. For example, at the beginning of vehicle startup, important information can be quickly obtained through a short STA-AP connection, and then converted to a more stable AP-STA connection in the subsequent process to support long-term data transmission and service provision. In short, synchronous switching based on preset time not only enhances the flexibility of the system, but also ensures efficient and reliable network connection, which is of great significance for improving driving safety and enhancing the in-vehicle interconnection experience.

[0070] In one embodiment, before step S103, the following steps S201 and S202 are also included:

[0071] Step S201: Acquire authentication information of the vehicle-mounted device.

[0072] In the application, when the in-vehicle infotainment system establishes a connection with the dashcam for the first time, it obtains the authentication information of the in-vehicle device. This may include the device serial number (SN number), manufacturer ID, or other specific identifiers. Assume that the in-vehicle infotainment system and the in-vehicle device are produced by the same manufacturer and support the same communication protocols and security standards. In this case, the in-vehicle infotainment system will verify this authentication information to confirm that the dashcam is indeed an authorized device and that data can be exchanged securely between them.

[0073] Step S202: confirming based on the authentication information that the in-vehicle device and the in-vehicle infotainment system belong to the same ecosystem.

[0074] In the application, the in-vehicle infotainment system receives the in-vehicle device, such as the dashcam, which provides a device serial number of "ABCD1234", and this serial number is in the preset whitelist of the in-vehicle infotainment system. The in-vehicle infotainment system will further check other relevant authentication information, such as device type, software version, etc., to ensure that both parties can work seamlessly. Once it is confirmed that the dashcam is trustworthy and that the two do belong to the same ecosystem, the in-vehicle infotainment system will continue to execute subsequent mode switching requests.

[0075] In the embodiment of the present application, for the vehicle-mounted devices belonging to the same ecosystem, after receiving the mode switching request signal, the mode switching can be performed at the preset switching time through the pre-made program, so as to avoid the vehicle-mounted devices being unable to recognize the mode switching request signal and unable to achieve the mode switching. This switching mechanism based on time synchronization not only improves the response speed of the system, but also ensures seamless collaboration between devices. Even in a complex network environment, it can ensure that the device can accurately and timely complete the mode switching, thereby avoiding the connection failure or delay caused by asynchronization. This is particularly important for application scenarios that require frequent switching between network roles, such as quickly establishing a stable network connection within a short time after the vehicle is started, or dynamically adjusting the network configuration according to different needs during driving. In addition, by confirming that the device belongs to the same ecosystem through authentication information and using the preset time for mode switching, it not only enhances the security, reliability and compatibility of the system, but also realizes highly automated network management, providing users with a smoother and more efficient Internet experience. While ensuring the security of data transmission, this mechanism also greatly improves the overall collaborative working ability and user experience of vehicle-mounted devices.

[0076] In one embodiment, the following step S301 is also included:

[0077] Step S301: When the vehicle-mounted device is operating in the station mode, the device is operated in the access point mode, and in response to a connection request signal from the vehicle-mounted device, a connection is established with the vehicle-mounted device.

[0078] The embodiment of the present application provides a method for establishing a connection when the vehicle-mounted device operates in station mode and the vehicle-mounted device operates in access point mode, so that the user can achieve seamless connection between the vehicle-mounted device and the vehicle-mounted infotainment system without manual intervention. The vehicle-mounted infotainment system can automatically identify and adapt to the status of the vehicle-mounted device, thereby providing a more convenient user experience.

[0079] The embodiment of the present application also provides a network connection mode switching method, which is applied to an in-vehicle device and can be executed by a processor of a terminal device when running a computer program with corresponding functions, by responding to a connection request signal sent by the in-vehicle infotainment system when running in access point mode, establishing a connection with the in-vehicle infotainment system; receiving a mode switching request signal sent by the in-vehicle infotainment system; sending a confirmation signal to the in-vehicle infotainment system; receiving a network name and password sent by the in-vehicle infotainment system; switching to a site mode, and sending a connection request signal to the in-vehicle infotainment system based on the network name and password of the in-vehicle infotainment system, wherein the in-vehicle infotainment system is used to switch to an access point mode, and respond to a connection request signal sent by the in-vehicle infotainment system to establish a connection with the in-vehicle device. The automatic switching of the network connection mode can be realized, making the switching of the network connection mode more convenient and ensuring driving safety.

[0080] like Figure 2 As shown, the network connection mode switching method provided in the embodiment of the present application includes the following steps S111 to S115:

[0081] Step S111 : When operating in the access point mode, in response to a connection request signal sent by the in-vehicle infotainment system, establish a connection with the in-vehicle infotainment system.

[0082] In the application, when the vehicle device is in access point mode, it responds to the connection request from the vehicle infotainment system, thus establishing a direct communication channel between the two.

[0083] Step S112: receiving a mode switching request signal sent by the in-vehicle infotainment system.

[0084] In the application, as the connection is established, the vehicle device receives a mode switch request from the vehicle infotainment system, indicating that it is ready to change its working mode. This request contains information about the upcoming network role change so that the vehicle device can prepare accordingly.

[0085] Step S113: Send a confirmation signal to the in-vehicle infotainment system.

[0086] In the application, to indicate that it is ready to accept the upcoming role change, the vehicle device sends a confirmation signal to the vehicle infotainment system.

[0087] Step S114: receiving the network name and password sent by the in-vehicle infotainment system.

[0088] In the application, the vehicle-mounted device will receive the SSID and password of the new network environment provided by the vehicle-mounted infotainment system. This information will be used to guide the vehicle-mounted device on how to correctly access the new wireless network that is about to be formed.

[0089] Step S115: switch to the site mode, and send a connection request signal to the vehicle infotainment system based on the network name and password of the vehicle infotainment system, wherein the vehicle infotainment system is used to switch to the access point mode, and establish a connection with the vehicle device in response to the connection request signal sent by the vehicle infotainment system.

[0090] In the application, the in-vehicle device completes the role transition from AP to STA, and uses the newly obtained network credentials to try to connect to the in-vehicle infotainment system that has become an AP.

[0091] The embodiment of the present application realizes the automatic switching of the network connection mode between the vehicle-mounted device and the vehicle-mounted infotainment system through the above method. This method significantly improves the convenience of use, reduces the trouble caused by manual adjustment of settings, and also ensures safety during driving, avoiding safety hazards caused by distracted operation. And the vehicle-mounted infotainment system is operated in access point mode as much as possible, so that it can be connected to more network devices, ensuring the efficiency of information acquisition and the ability of users to handle multiple tasks at the same time.

[0092] In one embodiment, step S115 specifically includes:

[0093] Switching to the station mode at a preset switching time, and sending a connection request signal to the in-vehicle infotainment system based on the network name and password of the in-vehicle infotainment system;

[0094] The mode switching request signal includes a preset switching time, and the in-vehicle infotainment system is used to switch to the access point mode at the preset switching time, and establish a connection with the in-vehicle device in response to a connection request signal sent by the in-vehicle device.

[0095] In one embodiment, the following step S211 is also included:

[0096] Step S211: When operating in station mode, sending a connection request signal to the in-vehicle infotainment system;

[0097] The in-vehicle infotainment system is used to operate in an access point mode and establish a connection with the in-vehicle device in response to a connection request signal sent by the in-vehicle device.

[0098] In one embodiment, step S211 includes the following steps S311 and S312:

[0099] Step S311, confirming the connection status;

[0100] In the application, suppose the vehicle device is currently running in STA mode and attempts to connect to the Wi-Fi network of the vehicle infotainment system. After the vehicle device sends a connection request signal, the vehicle infotainment system should respond to this request and establish a connection. However, due to some reasons (such as signal interference, incorrect password, or the vehicle infotainment system is temporarily unavailable), the connection may fail. In this case, the vehicle device will execute step S311 to confirm the connection status. By checking the connection status signal fed back by the vehicle infotainment system, the vehicle device can determine whether the connection is successfully established.

[0101] Step S312: If it is confirmed that the connection fails, switch to the access point mode and return to the step of establishing a connection with the in-vehicle infotainment system in response to a connection request signal sent by the in-vehicle infotainment system when running in the access point mode.

[0102] In the application, if the connection fails, the vehicle-mounted device will execute step S312, that is, switch back to AP mode and wait for the vehicle-mounted infotainment system to initiate a connection request again. In this way, the vehicle-mounted infotainment system can retry to establish a connection with the driving recorder. This process can ensure that even if the connection fails, the system can automatically recover and retry to establish a connection, thereby improving the success rate and stability of the connection.

[0103] The embodiment of the present application automatically switches back to AP mode and tries to connect again when the connection fails. This method not only improves the fault tolerance and self-recovery ability of the system, but also simplifies the user's operation process and enhances the reliability and robustness of the system. This mechanism provides users with a more efficient, convenient and reliable in-vehicle network environment.

[0104] In one embodiment, step S311 includes the following steps S411 to S413:

[0105] Step S411: confirming the connection status with the in-vehicle infotainment system based on the connection status signal fed back by the in-vehicle infotainment system.

[0106] In the application, after the vehicle device receives the connection status signal from the vehicle infotainment system, it will parse the signal to determine whether the connection is successful. For example, if the vehicle infotainment system returns a "connection successful" message, the vehicle device will think that the connection has been established. On the contrary, if it returns "connection failed", the dashcam will proceed to the next step.

[0107] Step S412: If the connection with the in-vehicle infotainment system is not successful, return to the step of sending a connection request signal to the in-vehicle infotainment system when operating in the station mode.

[0108] In the application, if the vehicle device fails to connect, it will try to send a connection request signal again. This retry mechanism can increase the probability of successful connection, especially when the initial connection attempt fails due to temporary problems (such as signal interference or a short device failure). For example, the vehicle device may try to connect every few seconds until it succeeds or reaches a preset number of retries.

[0109] Step S413: If the connection with the in-vehicle infotainment system is not successful within the specified time period, it is determined that the connection has failed.

[0110] In the application, if after multiple attempts, the connection still fails within a preset time period (such as 30 seconds or 3 minutes), the vehicle device will finally confirm that the connection has failed. At this point, the system will take further measures, such as switching back to access point mode (AP) to restart the entire connection process.

[0111] The embodiment of the present application confirms based on the connection status signal, attempts to connect multiple times, and confirms that the connection has failed when it fails within a specified time period. This method not only improves the fault tolerance and reliability of the system, but also simplifies the user's operation process and enhances the system's self-recovery ability. This mechanism provides users with a more efficient, convenient and reliable in-vehicle network environment.

[0112] The present application also provides a method for switching a network connection mode. Figure 3 As shown, the following steps S11 to S28 are included:

[0113] Step S11, start.

[0114] Step S12: Power on the product.

[0115] In the application, after the vehicle-mounted device is powered on, it will perform a self-test to determine whether the vehicle-mounted device is in access point mode or in station mode. If it is in station mode, step S21 is executed, and if it is in access point mode, step S13 is executed.

[0116] Step S13: When the in-vehicle infotainment system is in the station mode and the in-vehicle device is in the access point mode, the in-vehicle infotainment system sends a connection request to the in-vehicle device.

[0117] Step S14, receiving the request and responding to the connection.

[0118] Step S15: Connection successful.

[0119] Step S16: Determine whether it is an ecological product.

[0120] In the application, the in-vehicle infotainment system obtains the authentication information of the in-vehicle device to determine whether it belongs to the same ecosystem. The authentication information may include at least one of the serial number, manufacturer ID or other identifier of the device. If the in-vehicle device passes the authentication, the system will proceed to step S17.

[0121] Step S17: Send a mode switching request signal.

[0122] In the application, after confirming that the vehicle-mounted device is an ecological product, the vehicle-mounted infotainment system will send a mode switching request signal to the vehicle-mounted device. This signal contains the upcoming role switching information and possible preset switching time.

[0123] Step S18: Receive the request and reply OK, entering the ready state.

[0124] In the application, after receiving the mode switching request signal, the vehicle-mounted device will reply with an "OK" signal, indicating that it is ready for mode switching. At this time, the vehicle-mounted device enters the ready state and waits for the preset switching time to arrive.

[0125] Step S19: Send the vehicle computer SSID, password and other information.

[0126] In the application, the in-vehicle infotainment system will send its own Wi-Fi network name (SSID) and password to the in-vehicle device. This information is used to enable the in-vehicle device to connect to the new network environment provided by the in-vehicle infotainment system.

[0127] Step S20: After receiving the vehicle machine SSID and password, both parties automatically complete the switch at the specified time.

[0128] In the application, after the vehicle device receives the SSID and password of the vehicle infotainment system, it will automatically switch to station mode at a preset time. At the same time, the vehicle infotainment system will also switch to access point mode at the same time. In this way, both parties will complete the role conversion and re-establish the connection at almost the same time.

[0129] Step S21: When the in-vehicle infotainment system is in access point mode and the in-vehicle device is in station mode, the in-vehicle device sends a connection request to the in-vehicle infotainment system.

[0130] Step S22, receive the request and respond to the connection.

[0131] Step S23: Send the connection status result.

[0132] Step S24: Accept the connection status result.

[0133] Step S25: Determine whether the connection with the vehicle computer is successful.

[0134] In the application, the vehicle-mounted device determines whether the connection is successfully established based on the connection status result sent by the vehicle-mounted infotainment system. If the connection is successful, the system will execute step S26; if the connection fails, the system will execute step S27.

[0135] Step S26: normal use.

[0136] Step S27, continue to send connection requests to the vehicle computer. If the connection still fails after 3 minutes, automatically switch to AP mode and execute step S13.

[0137] Step S28, end.
