Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a communication control method, electronic device, and medium. Background Technology

[0002] With the development of communication technology, more and more cars are being equipped with in-vehicle infotainment systems, which can transmit data with other smart devices. For example, a mobile phone can be connected to the in-vehicle infotainment system, allowing the system to perform some of the functions of mobile phone applications, such as navigation, music control, weather preview, or voice control.

[0003] Most vehicle models support wired connections. Electronic devices can connect to the vehicle's infotainment system via a wired connection. However, if a user accidentally touches the wired connection port or the vehicle travels on a bumpy road, the connection may become faulty. This can cause jitter in the wired signal transmitted between the electronic device and the vehicle's infotainment system, weakening the signal strength. Consequently, the communication connection at the wired interface may suddenly be interrupted while the electronic device maintains the connection, preventing the user from using certain connected car functions. For example, if a user is driving on a highway and using connected car navigation, a sudden signal interruption could cause them to miss a turn, or if a user is listening to music in the car, the music may suddenly stop. Summary of the Invention

[0004] The purpose of this application is to provide a communication control method, electronic device, and medium that can solve the problem of communication connection loss when using vehicle networking functions via wired means.

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] Among the related technologies, there are two connection methods to enable the interconnection between vehicles and electronic devices.

[0029] One type is a wired connection based on a data cable, which can be a Micro USB interface data cable, a Type-C interface data cable, or a Lightning interface data cable, etc.; the other type is a wireless connection based on technologies such as Bluetooth, Wireless Local Area Networks (WLAN), ZigBee protocol, Near Field Communication (NFC), Radio Frequency Identification (RFID), or Ultra Wide Band (UWB).

[0030] In wired connections, the signal quality transmitted via the wired interface primarily depends on the design and selection of modules such as the electronic equipment, data cable, and vehicle infotainment system. The performance of functional modules related to the data cable within the electronic equipment is relatively stable, having minimal impact on the wired signal transmission. Different types of data cables vary in length and performance, significantly affecting the wired signal transmission. Due to limited space on the main control board, extension cables corresponding to the wired interface are added inside the vehicle infotainment system; these extension cables significantly impact the wired signal transmission. Regardless of whether it's the data cable or the extension cable, poor wired signal quality can lead to communication disconnections.

[0031] The communication control method, electronic device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0032] The communication control method can be applied to electronic devices, and can be executed by the hardware or software within the electronic device. The electronic devices mentioned in this application include, but are not limited to, mobile communication devices such as mobile phones, tablets, computers, cameras, and wearable devices. The following description uses an electronic device as the executing entity to illustrate the communication control method provided in this application.

[0033] Figure 1 This is one of the schematic diagrams of the communication control system structure of the communication control method provided in this application embodiment. The communication control method provided in this application embodiment can be applied to, for example... Figure 1 The communication control system shown.

[0034] like Figure 1 As shown, the communication control system of this application embodiment may include an electronic device 100 and a vehicle-mounted system 130. The electronic device 100 and the vehicle-mounted system 130 are connected via a wired interface; wherein, the electronic device 100 may include an application processor 110 and a signal adjustment module 120.

[0035] In actual implementation, the electronic device 100 can be wired to the vehicle infotainment system 130 via a data cable. It is understood that both ends of the data cable are equipped with wired interfaces, and both the electronic device 100 and the vehicle infotainment system 130 have interfaces for connecting to the wired data cable.

[0036] It should be noted that "vehicle infotainment system" is a shorthand for in-vehicle infotainment products installed in cars. Functionally, vehicle infotainment systems enable information communication between the user terminal and the car, between the car and the outside world, or between cars. Currently, most vehicle infotainment systems are installed in the car's center console.

[0037] After the electronic device 100 and the vehicle system 130 in this embodiment of the application are connected by a wire, a communication connection corresponding to the wired interface can be established based on protocols such as USB 2.0 or USB 3.2.

[0038] In the USB 2.0 protocol, in order to prevent interference signals from affecting normal signal transmission, the Squelch parameter and the HS_Disconnect parameter were designed.

[0039] When the signal amplitude received by an electronic device or vehicle system is less than the threshold set by the `Squelch` parameter, the received signal will be identified as interference, not decoded, and filtered out. The electronic device will not receive a signal, meaning no data transmission will occur. This will lead to signal disconnection issues when using wired vehicle-to-everything (V2X) connectivity, impacting the user experience. Similarly, when the signal amplitude received by an electronic device exceeds the threshold set by the `HS_disconnect` parameter, the communication connection will be considered disconnected, also causing signal disconnection issues when using wired V2X connectivity, affecting the user experience.

[0040] Figure 2 This is one of the flowcharts illustrating the communication control method provided in the embodiments of this application. For example... Figure 2 As shown, the communication control method includes:

[0041] Step 210: Based on the first signal received by the application processor 110, determine that the communication connection corresponding to the wired interface has been disconnected; the first signal is the signal transmitted when the electronic device 100 and the vehicle system 130 establish a wireless connection.

[0042] Step 220: The control signal adjustment module 120 enhances the signal strength of the second signal, which is transmitted through a wired interface.

[0043] In practice, the electronic device 100 and the vehicle infotainment system 130 can be connected via a wired data cable. This data cable can be a Lightning cable, a Micro USB cable, or a Type-C cable, etc. The types of wired interfaces at both ends of the data cable can be: Micro USB, Mini USB, Lightning, Type-A, Type-B, or Type-C, etc.

[0044] In this embodiment, one end of the data cable can be inserted into the electronic device 100, and the other end can be inserted into the vehicle infotainment system 130. The wired interface at one end of the data cable is typically a Type-A interface, used for insertion into the vehicle infotainment system 130; the wired interface at the other end of the data cable connects to the electronic device 100. Taking a mobile phone as an example, the mobile phone's wired interface can be a Micro USB interface, a Mini USB interface, a Type-B interface, a Lightning interface, or a Type-C interface, etc. The type of wired interface at both ends of the data cable can be set according to actual conditions, and this application does not impose specific limitations on this.

[0045] In some scenarios, when the electronic device 100 and the vehicle infotainment system 130 are connected via a wired data cable, the user can use the vehicle networking function normally. However, when the car travels over bumpy roads, the car body vibrates, causing the wired signal transmitted via the data cable to jitter. Furthermore, the wired connection experiences path attenuation. Although the data cable remains connected, the signal strength of the wired signal may not meet the communication requirements, causing the electronic device 100 and the vehicle infotainment system 130 to disconnect from the wired interface.

[0046] It should be noted that, in addition to wired connection via data cable, electronic device 100 and vehicle infotainment system 130 can also connect wirelessly. This ensures that even when the wired communication connection is lost, electronic device 100 and vehicle infotainment system 130 can still transmit data wirelessly. For example, they can connect via Bluetooth, ZigBee network, or Wireless Fidelity (Wi-Fi).

[0047] When the vehicle infotainment system 130 detects that the communication connection corresponding to the wired interface is disconnected and the electronic device 100 has established a wireless connection with the vehicle infotainment system 130, the vehicle infotainment system 130 can send a first signal to the electronic device 100 via wireless communication, so as to promptly report to the electronic device 100 that the vehicle infotainment system 130 is in a disconnected state.

[0048] In this embodiment, a signal transmitter can also be provided in the data cable. When the vehicle infotainment system 130 or the data cable detects that the communication connection corresponding to the wired interface is disconnected, the signal transmitter in the vehicle infotainment system 130 or the data cable can send a first signal to the electronic device 100.

[0049] The electronic device 100 can receive the first signal through a functional module for receiving wireless signals, such as a signal receiver or Bluetooth module, and send the first signal to the application processor 110 of the electronic device 100.

[0050] After receiving the first signal, the application processor 110 in the electronic device 100 can send a control signal to the signal adjustment module 120, thereby controlling the signal adjustment module 120 to dynamically adjust the signal strength of the second signal transmitted through the wired interface, enhancing the signal strength of the second signal to achieve the signal strength required for the electronic device 100 and the vehicle system 130 to restore communication connection. The signal strength required for communication connection can be determined based on the Universal Serial Bus (USB) communication protocol, and is not specifically limited here.

[0051] The signal adjustment module 120 can be built based on a signal enhancement chip, which will be described in subsequent embodiments. The second signal refers to a differential signal transmitted via a wired interface, which may include a data minus (DM) signal and a data positive (DP) signal.

[0052] The signal adjustment module 120 in this embodiment can monitor the signals transmitted by data cables of different lengths and types in real time and adjust the signal strength in real time, which has a wide range of applications.

[0053] According to the communication control method provided in the embodiments of this application, the connection status of the communication connection corresponding to the wired interface can be determined in a timely manner by receiving the first signal from the application processor. The signal strength of the second signal transmitted based on the wired interface can be dynamically adjusted in real time according to the connection status, thereby enhancing the signal strength of the second signal to achieve the signal strength required to establish the communication connection corresponding to the wired interface, reducing disconnection and improving the user's in-vehicle experience. In addition, the addition of a signal adjustment module to the electronic device results in a simple circuit structure and low cost.

[0054] In some embodiments, the signal adjustment module 120 includes at least one of the following: a Redriver chip or a Retimer chip.

[0055] In actual implementation, the signal adjustment module 120 can be built based on a signal enhancement chip. The signal enhancement chip can be, but is not limited to, a Redriver chip and a Retimer chip, or other chips with signal adjustment functions. No specific limitation is made here.

[0056] It should be noted that a Redriver chip can function as a signal repeater, amplifying the signal and increasing signal quality or strength at high-speed interfaces. Specifically, it adjusts and corrects channel signal loss at the transmitting end using techniques such as equalization and pre-emphasis, and restores signal integrity at the receiving end.

[0057] A retimer chip is a mixed-signal device that transmits both digital and analog signals. Analog signals entering the retimer chip are converted back to digital signals, and then back to analog signals before being transmitted. It has sensing capabilities, enabling it to completely recover and retransmit the data signal. Specifically, it extracts the embedded clock from the input signal using its internal clock data recovery circuit, and then retransmits the data using the complete, undamaged clock signal, creating a new copy of the original data signal. This mode of recovering the data first and then retransmitting the signal through a serial channel effectively solves the problem of signal strength attenuation.

[0058] In this embodiment, one or more of a Redriver chip or a Retimer chip can be added to the electronic device 100. Both the Redriver chip and the Retimer chip can dynamically adjust the signal strength of the second signal transmitted via the USB interface, enabling the vehicle infotainment system 130 and the electronic device 100 to quickly re-establish the communication connection corresponding to the USB interface, thereby rapidly restoring the vehicle networking function and improving the user's in-vehicle experience.

[0059] In some embodiments, the control signal adjustment module 120 enhances the signal strength of the second signal, including:

[0060] Based on the signal strength of the second signal, the signal strength configuration parameters of the signal adjustment module 120 are adjusted to enhance the signal strength of the second signal.

[0061] In practice, different signal strength configuration parameters can be used for different types and lengths of data lines.

[0062] After receiving the control signal from the application processor 110, the signal adjustment module 120 determines the signal strength configuration parameters of the data line based on its length and type, and writes these parameters into the signal adjustment module 120. Based on these parameters, it adjusts the signal strength of the second signal to restore its integrity, thereby enhancing its signal strength.

[0063] According to the communication control method provided in the embodiments of this application, the signal strength of the second signal can be adjusted in real time through the signal adjustment module, thereby enhancing the signal strength of the second signal and reducing the disconnection of the communication connection corresponding to the wired interface.

[0064] In some embodiments, after the control signal adjustment module 120 enhances the signal strength of the second signal, the communication control method further includes:

[0065] If the signal strength of the second signal meets the strength threshold, a new communication connection corresponding to the wired interface is re-established with the vehicle's infotainment system 130.

[0066] If the duration of the communication connection corresponding to the wired interface exceeds the time threshold, the signal strength configuration parameters are saved.

[0067] In this embodiment, the application processor 110 controls the signal adjustment module 120 to adjust the signal strength of the second signal until the signal strength of the second signal meets the strength threshold, thereby enabling the electronic device 100 and the vehicle system 130 to re-establish a communication connection via a wired interface. The strength threshold can be set based on the USB protocol or according to the relevant device parameters of the electronic device 100 or the vehicle system 130; no specific limitation is made here.

[0068] If the communication connection corresponding to the wired interface is held for a duration exceeding a time threshold, the communication connection can be considered to have stabilized, and the application processor 110 then saves the signal strength configuration parameters of the signal adjustment module 120. The time threshold can be determined based on actual needs and is not specifically limited here.

[0069] Based on the signal strength configuration parameters of the signal adjustment module 120, the electronic device 100 and the vehicle system 130 can transmit data. Then, the user can use the vehicle networking function normally through the electronic device 100. For example, some applications in the electronic device 100 can be projected onto the corresponding display screen of the vehicle system 130.

[0070] According to the communication control method provided in the embodiments of this application, the signal strength of the second signal is adjusted by the signal adjustment module so that the signal strength of the second signal meets the strength threshold. After the electronic device and the vehicle are connected to maintain a stable communication connection through the wired interface, the dynamically adjusted signal strength configuration parameters are saved and used in the subsequent vehicle connection, thereby further improving the stability of the communication connection.

[0071] In some embodiments, after determining that the communication connection corresponding to the wired interface has been disconnected, the communication control method further includes:

[0072] Determine the insertion status of the wired interface;

[0073] When the wired interface is inserted into the vehicle infotainment system 130, the control signal adjustment module 120 enhances the signal strength of the second signal.

[0074] Understandably, upon receiving the first signal, the application processor 110 can determine the insertion status of the data cable and confirm whether the wired interface is inserted into the vehicle infotainment system 130.

[0075] If it is determined that the wired interface is not plugged into the vehicle infotainment system 130, the application processor 110 will not send a control signal to the signal adjustment module 120, and the signal adjustment module 120 will not perform signal strength adjustment. The vehicle infotainment system 130 can send a prompt message to the electronic device 100 to inform the user that the data cable is disconnected, so that the user can reconnect the data cable.

[0076] If it is determined that the wired interface is inserted into the vehicle infotainment system 130, the application processor 110 can send a control signal to the signal adjustment module 120 to control the signal adjustment module 120 to enhance the signal strength of the second signal.

[0077] Figure 3 This is the second schematic diagram of the communication control system structure of the communication control method provided in this application embodiment. The communication control method provided in this application embodiment can be applied to, for example... Figure 3 The communication control system shown.

[0078] The communication control system may include a mobile phone and a vehicle-mounted infotainment system. The mobile phone and the vehicle-mounted infotainment system are connected via a wired USB cable. The mobile phone may include an application processor, Bluetooth connectivity, a signal conditioning module (Redriver chip or Retimer chip), a USB switch, and an audio switch. The vehicle-mounted infotainment system may include vehicle-mounted Bluetooth and a vehicle-mounted infotainment system.

[0079] The USB data cable is mainly used to connect the mobile phone and the vehicle system, serving as the hardware medium for data transmission. The USB switch can be a DIO5000, a high-speed, low-power double-pole / double-throw analog switch used to switch high-speed USB 2.0 signals in handheld devices (such as mobile phones, digital cameras, and laptops, or devices with hubs or controllers). The audio switch can be an FSA4480, a high-performance multimedia switch that allows the transmission of USB 2.0 signals, analog audio signals, and analog microphone signals.

[0080] The application processor is responsible for running the mobile phone software system, implementing the functions of the mobile phone terminal, and controlling peripheral devices. The application processor is the control center of the entire mobile phone.

[0081] The phone's Bluetooth can be used to receive signals sent by the car's Bluetooth, thereby confirming whether the wired interface corresponding to the phone's USB data cable is in a communication connection state.

[0082] The Redriver or Retimer chip is used to adjust the signal strength of the DP / DM signal transmitted via the USB data cable, with the aim of enhancing the signal strength of the DP / DM signal.

[0083] The USB switch can switch between the central processing unit (CPU), the charging microcontroller unit (MCU), and the power management chip.

[0084] The audio switch allows you to toggle between headphone, USB, and OTG (On-The-Go) functions. OTG is a technology that allows a phone to connect to various peripherals without the need for a computer.

[0085] Figure 4 This is a second flowchart illustrating the communication control method provided in the embodiments of this application. Figure 4 As shown, the communication control method provided in this application embodiment may include:

[0086] One end of the USB cable connects to the phone, and the other end connects to the vehicle's infotainment system. The in-vehicle display shows the connection information between the phone and the infotainment system.

[0087] Normal data transmission occurs between the mobile phone and the vehicle's infotainment system. The application processor outputs data based on the original signal strength configuration parameters of the Redriver or Retimer chip in the signal adjustment module. The in-vehicle display shows that the infotainment system and the mobile phone are in normal communication connection via USB data cable.

[0088] When the communication connection corresponding to the USB interface is disconnected, the vehicle infotainment system generates a disconnection signal. It should be noted that the disconnection occurs because the DP / DM signal attenuates during transmission, causing the signal strength to be insufficient to establish a communication connection via the USB interface, ultimately leading to the disconnection.

[0089] The car's Bluetooth system can send a disconnection signal to the phone's Bluetooth system. After receiving the disconnection signal, the phone's Bluetooth system sends a feedback to the application processor.

[0090] The application processor determines whether the USB port is plugged in. If the USB port is not plugged in, the application processor does not perform any processing, and the in-vehicle display can show that the mobile phone and the vehicle system are not communicating via the USB port. If the USB port is plugged in, the application processor controls the Redriver chip or Retimer chip to adjust the signal strength of the DP / DM signal transmitted through the USB data cable to enhance the signal strength of the DP / DM signal until the mobile phone and the vehicle system can communicate normally.

[0091] After the vehicle's infotainment system and the mobile phone have established a stable communication connection via USB for a period of time, the application processor saves the dynamically adjusted signal strength configuration parameters and uses these parameters in subsequent vehicle-to-vehicle connections. Once the application processor confirms that the vehicle's infotainment system has re-established the communication connection via USB, the mobile phone and the vehicle's infotainment system can use the vehicle networking function normally.

[0092] Figure 5 This is the third schematic diagram of the communication control system structure of the communication control method provided in this application embodiment. The communication control method provided in this application embodiment can be applied to, for example... Figure 5 The communication control system structure is shown.

[0093] It should be noted that, with Figure 3 The communication control system shown is different from that shown. Figure 5 The wireless connection of the communication control system shown is not achieved through the vehicle's Bluetooth and the phone's Bluetooth. Instead, a wireless signal transmitter is added to the USB data cable, and a wireless signal receiver is added to the phone to achieve a wireless connection.

[0094] Figure 6 This is the third flowchart illustrating the communication control method provided in the embodiments of this application. Figure 6 As shown, the communication control method provided in this application embodiment may include:

[0095] One end of the USB cable connects to the phone, and the other end connects to the vehicle's infotainment system. The in-vehicle display shows the connection information between the phone and the system.

[0096] The mobile phone and the vehicle's infotainment system exchange data normally. The application processor outputs data based on the original signal strength configuration parameters of the signal adjustment module. The in-vehicle display shows that the infotainment system and the mobile phone are communicating normally via USB data cable.

[0097] When the communication connection corresponding to the USB interface is disconnected, the vehicle infotainment system generates a disconnection signal. It should be noted that the disconnection occurs because the DP / DM signal attenuates during transmission, causing the signal strength to be insufficient to establish a communication connection via the USB interface, ultimately leading to the disconnection.

[0098] The wireless transmitter inside the USB data cable sends a disconnection signal from the vehicle's infotainment system to the wireless receiver inside the phone. After receiving the disconnection signal, the wireless receiver sends it back to the application processor.

[0099] The application processor determines whether the USB port is plugged in. If the USB port is not plugged in, the application processor does not perform any processing, and the in-vehicle display can show that the phone and the vehicle system are not communicating via the USB data cable. If the USB port is plugged in, the application processor controls the Redriver chip or Retimer chip to adjust the signal strength of the DP / DM signal transmitted via the USB data cable to enhance the signal strength of the DP / DM signal until the phone and the vehicle system can communicate normally.

[0100] After the vehicle's infotainment system and the mobile phone have established a stable communication connection via USB for a period of time, the application processor saves the dynamically adjusted signal strength configuration parameters and uses these parameters in subsequent vehicle-to-vehicle connections. Once the application processor confirms that the vehicle's infotainment system has re-established the communication connection via USB, the mobile phone and the vehicle's infotainment system can use the vehicle networking function normally.

[0101] According to the communication control method provided in the embodiments of this application, the signal parameters are dynamically adjusted in real time by utilizing the internal circuit of the mobile phone, USB data cable, and Redriver chip or Retimer chip while ensuring the integrity of the vehicle circuit, so as to ensure that the vehicle unit will not disconnect. The circuit is very simple, low cost and easy to implement. It can solve the pain point of vehicle unit disconnection for users, reduce user complaints and improve the user's in-vehicle experience.

[0102] The communication control method provided in this application can be executed by an electronic device 700. This application uses the electronic device 700 executing the communication control method as an example to illustrate the electronic device 700 provided in this application.

[0103] This application also provides an electronic device 700. Figure 7 This is one of the structural schematic diagrams of the electronic device provided in the embodiments of this application. For example... Figure 7 As shown, the electronic device 700 includes an application processor 710 and a signal adjustment module 720, and the electronic device 700 is connected to the vehicle's infotainment system via a wired interface.

[0104] The application processor 710 is used to control the signal adjustment module 720 to enhance the signal strength of a second signal based on the received first signal, the second signal being transmitted through the wired interface;

[0105] The first signal is used to indicate that the communication connection corresponding to the wired interface has been disconnected. The first signal is a signal transmitted when the electronic device 700 establishes a wireless connection with the vehicle system.

[0106] According to the electronic device provided in the embodiments of this application, the application processor receives a first signal, thereby timely determining the connection status of the communication connection corresponding to the wired interface. It can also control the signal adjustment module in real time to dynamically adjust the signal strength of the second signal transmitted based on the wired interface according to the connection status, thereby enhancing the signal strength of the second signal to achieve the signal strength required to establish the communication connection corresponding to the wired interface, reducing disconnection and improving the user's in-vehicle experience. In addition, the electronic device is also equipped with a signal adjustment module, which has a simple circuit structure and low cost.

[0107] In some embodiments, the application processor 710 is specifically used for:

[0108] Based on the signal strength of the second signal, the signal strength configuration parameters of the signal adjustment module are adjusted to enhance the signal strength of the second signal.

[0109] In some embodiments, the application processor 710 is specifically used for:

[0110] After the signal adjustment module enhances the signal strength of the second signal, and the signal strength of the second signal meets the strength threshold, the communication connection corresponding to the wired interface is re-established with the vehicle system.

[0111] If the duration of the communication connection corresponding to the wired interface exceeds a time threshold, the signal strength configuration parameters are saved.

[0112] In some embodiments, the application processor 710 is further configured to:

[0113] After determining that the communication connection corresponding to the wired interface has been disconnected, the insertion status of the wired interface is then determined.
