In the related art, there are two connection methods to realize the interconnection between the vehicle and the electronic equipment.

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

In the wired connection mode, the quality of the signal transmitted by the wired interface mainly depends on the design and selection of modules such as electronic equipment, data lines, and vehicles. The performance of the functional modules related to the data line inside the electronic device is relatively stable, and has little impact on the wired signal transmitted by the data line; different types of data lines have different lengths, and the performance varies greatly, which has a greater impact on the wired signal transmitted by the data line ; Due to the limited layout of the main control board, an extension cable corresponding to the wired interface will be added inside the car, and the extension cable will have a greater impact on the wired signal transmitted by the data cable. Whether it is a data cable or an extension cable, there will always be problems with poor wired signal quality that will cause the communication connection to be disconnected.

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

Wherein, the communication control method can be applied to electronic equipment, and specifically can be executed by hardware or software in the electronic equipment. The electronic devices mentioned in the embodiments of the present application include but are not limited to mobile communication devices such as mobile phones, tablet computers, computers, cameras, and wearable devices. The communication control method provided in the embodiments of the present application will be described below using electronic devices as the execution subject as an example. .

FIG. 1 is one of the structural diagrams of a communication control system of a communication control method provided in an embodiment of the present application. The communication control method provided in the embodiment of the present application may be applied to the communication control system shown in FIG. 1 .

As shown in FIG. 1 , the communication control system in this embodiment of the present application may include an electronic device 100 and a car machine 130 . The electronic device 100 and the car machine 130 are connected through a wired interface; wherein, the electronic device 100 may include an application processor 110 and a signal adjustment module 120 .

In actual implementation, the electronic device 100 may be wired with the vehicle 130 through a data cable. It can be understood that both ends of the data line are also provided with wired interfaces, and the electronic device 100 and the car machine 130 are provided with interfaces for connecting with the wired interfaces of the data lines.

It should be noted that the car machine refers to the abbreviation of the in-vehicle infotainment product installed in the car. The car machine can realize the information communication between the user terminal and the car, the car and the outside world, or the car and the car. At present, most of the car machines are installed In the car center console.

After the electronic device 100 and the car machine 130 in the embodiment of the present application are wired connected, a communication connection corresponding to the wired interface can be established based on protocols such as USB2.0 or USB3.2.

In the USB2.0 protocol, in order to prevent interference signals from affecting normal signal transmission, the parameters of squelch detection (Squelch) and high-speed device disconnection detection (HS_Disconnect) are designed.

When the amplitude of the signal received by the electronic device or the vehicle is less than the threshold set by the Squelch parameter, the received signal will be judged as an interference signal, and will not be decoded, and the interference signal will be filtered out, and the electronic device will not receive the signal. That is, there is no data transmission, which leads to the problem of signal disconnection when the user uses the wired method for the Internet of Vehicles function, which affects the user experience. Similarly, when the amplitude of the signal received by the electronic device is greater than the threshold set by the HS_disconnect parameter, it will be judged that the electronic device is disconnected from the communication connection, which will also cause the signal disconnection problem when the user uses the wired method for the car networking function. affect the user experience.

Fig. 2 is one of the schematic flowcharts of the communication control method provided by the embodiment of the present application. As shown in Figure 2, the communication control method includes:

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 a signal transmitted when the electronic device 100 establishes a wireless connection with the vehicle 130;

Step 220, control the signal adjustment module 120 to increase the signal strength of the second signal, and the second signal is transmitted through the wired interface.

In actual implementation, the electronic device 100 and the car machine 130 may be connected via a data cable. Wherein, the data cable may be a Lighting data cable, a Micro USB interface data cable, or a Type-C data cable. The type of the wired interface at both ends of the data cable may be: Micro USB interface, Mini USB interface, Lightning interface, Type-A interface, Type-B interface or Type-C interface, etc.

In the embodiment of the present application, one end of the data cable can be plugged into the electronic device 100 , and the other end can be plugged into the car machine 130 . The wired interface at one end of the data line is usually a Type-A interface, which is used to plug into the vehicle 130; the wired interface at the other end of the data line is connected to the electronic device 100.

However, in some scenarios, when the electronic device 100 and the car machine 130 are connected via a data cable, the user can normally use the Internet of Vehicles function. When the car passes through a bumpy road, the body of the car will vibrate, causing the wired signal transmitted by the data line to jitter, and there is path attenuation in the wired connection. Although the data line is still connected, the signal strength of the wired signal may not be satisfactory at this time. The communication connection request causes the electronic device 100 and the car machine 130 to disconnect the communication connection corresponding to the wired interface.

It should be noted that, in addition to the wired connection through the data cable, the electronic device 100 and the car-machine 130 can also be connected wirelessly, so as to ensure that the electronic device 100 and the car-machine 130 are still connected when the communication connection corresponding to the wired interface is disconnected. Data transmission may take place via a wireless communication link. For example: a Bluetooth connection, a ZigBee network connection or a wireless fidelity (Wireless Fidelity, Wi-Fi) connection, etc. can be performed.

When the in-vehicle 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 in-vehicle 130, the in-vehicle 130 can send a first signal to the electronic device 100 through wireless communication, so that the The electronic device 100 reports back that the car machine 130 is in a disconnected state.

In the embodiment of the present application, a signal transmitter may also be provided in the data line. When the car-machine 130 or the data line detects that the communication connection corresponding to the wired interface is disconnected, the signal transmitter in the car-machine 130 or the data line can both send a first signal to the electronic device 100 .

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

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, so that the signal adjustment module 120 can be controlled to dynamically adjust the signal strength of the second signal transmitted through the wired interface to enhance The signal strength of the second signal is such that it reaches the signal strength required by the electronic device 100 and the car machine 130 to restore the communication connection. The signal strength required for the communication connection may be determined based on a universal serial bus (Universal Serial Bus, USB) communication protocol, which is not specifically limited herein.

Wherein, the signal adjustment module 120 may be constructed based on a signal enhancement chip, and the signal enhancement chip will be described in subsequent embodiments. The second signal refers to a differential signal transmitted based on a wired interface, and the differential signal may include a data negative (Data Minus, DM) signal and a data positive (Data Positive, DP) signal.

The signal adjustment module 120 in the embodiment of the present application can monitor the signals transmitted by different lengths and different types of data lines in real time, and adjust the signal strength in real time, which has a wide range of applications.

According to the communication control method provided by the embodiment of the present application, the connection status of the communication connection corresponding to the wired interface can be determined in time through the first signal received by the application processor, and the signal adjustment module can be adjusted in real time according to the connection status. The signal strength of the transmitted second signal is dynamically adjusted, so that the signal strength of the second signal can be enhanced to reach the signal strength of the communication connection corresponding to the wired interface, reducing disconnection and improving the user's vehicle experience; in addition, in the electronic A signal adjustment module is added to the device, and the circuit structure is simple and the cost is low.

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

In actual implementation, the signal adjustment module 120 can be constructed based on a signal enhancement chip, and the signal enhancement chip can include but not limited to a Redriver chip and a Retimer chip, or other chips with a signal adjustment function, which are not specifically limited here.

It should be noted that the Redriver chip can be a chip that functions as a signal repeater, which can amplify signals and increase signal quality or signal strength on high-speed interfaces. Specifically, by using techniques such as equalization and pre-emphasis to adjust and correct the loss of the channel signal on the transmission end, and restore the integrity of the signal on the receiving end.

A Retimer chip is a hybrid device of digital and analog signals. The analog signal entering the Retimer chip will be restored to a digital signal, and then re-transmitted as an analog signal. It is sentient and fully recovers the data signal re-emission. Specifically, the embedded clock in the input signal is extracted through the clock data recovery circuit embedded in it, and then the complete unattenuated clock signal is used to retransmit the data to form a new copy of the original data signal. The Retimer chip first recovers the data and then resends the signal through the serial channel, which can effectively solve the problem of signal strength attenuation.

In the embodiment of the present application, one or more of a Redriver chip or a Retimer chip may 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 based on the USB interface, so that the car machine 130 and the electronic device 100 can re-establish the communication connection corresponding to the USB interface as soon as possible, thereby quickly restoring the Internet of Vehicles function and improving the user experience. in-vehicle experience.

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

Based on the signal strength of the second signal, a signal strength configuration parameter of the signal adjustment module 120 is adjusted, and the signal strength configuration parameter is used to enhance the signal strength of the second signal.

In actual implementation, for data lines of different types and lengths, different signal strength configuration parameters may correspond to them.

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 the length and type of the data line, and writes the signal strength configuration parameters into the signal adjustment module 120 . And based on the signal strength configuration parameter, the signal strength of the second signal is adjusted to restore the integrity of the second signal, so that the signal strength of the second signal can be enhanced.

According to the communication control method provided by the embodiment of the present application, the signal adjustment module can realize real-time adjustment of the signal strength of the second signal, thereby enhancing the signal strength of the second signal and reducing disconnection of the communication connection corresponding to the wired interface.

When the signal strength of the second signal meets the strength threshold, re-establish the communication connection corresponding to the wired interface with the car machine 130;

When the holding time of the communication connection corresponding to the wired interface exceeds the time threshold, the signal strength configuration parameter is saved.

In the embodiment of the present application, 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, so that the electronic device 100 and the car machine 130 can reconnect to each other through the wired interface. Establish a communication connection. Wherein, the intensity threshold can be set based on the USB protocol, or can be set according to device-related parameters corresponding to the electronic device 100 or the vehicle 130 , which is not specifically limited here.

When the holding time of the communication connection corresponding to the wired interface exceeds the time threshold, it can be considered that the communication connection corresponding to the wired interface tends to be stable, and the application processor 110 then saves the signal strength configuration parameters of the signal adjustment module 120 . Wherein, the time threshold may be determined according to actual requirements, and is not specifically limited here.

Based on the signal strength configuration parameters of the signal adjustment module 120, the electronic device 100 and the vehicle 130 can perform data transmission, and the user can use the electronic device 100 to use the Internet of Vehicles function normally, for example: some applications in the electronic device 100 can be projected to the on the corresponding display screen of the car machine 130.

According to the communication control method provided by the embodiment of the present 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, and after the electronic device and the vehicle maintain a stable communication connection through the wired interface , save the dynamically adjusted signal strength configuration parameters, and use the signal strength configuration parameters in the subsequent car-machine connection, further improving the stability of the communication connection.

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

Determine the plug-in state of the wired interface;

When it is determined that the wired interface is plugged into the vehicle machine 130, the control signal adjustment module 120 increases the signal strength of the second signal.

It can be understood that, when the application processor 110 receives the first signal, it can judge the insertion state of the data line, and confirm whether the wired interface is inserted into the vehicle machine 130 .

If it is determined that the wired interface is not plugged into the vehicle machine 130, the application processor 110 does not send a control signal to the signal adjustment module 120, and the signal adjustment module 120 does not perform signal strength adjustment. The in-vehicle device 130 may send prompt information to the electronic device 100 to remind the user that the data line is disconnected, so as to facilitate the user to reconnect the data line.

If it is determined that the wired interface is plugged into the vehicle machine 130, the application processor 110 may send a control signal to the signal adjustment module 120, so as to control the signal adjustment module 120 to enhance the signal strength of the second signal.

The on-board display can display the normal communication connection between the car-machine system and the mobile phone through the USB data cable.

When the communication connection corresponding to the USB interface is in a communication disconnection state, the vehicle-machine system generates a vehicle-machine disconnection signal. It should be noted that the disconnection of the car and the machine is because the signal strength of the DP/DM signal does not meet the signal strength required to establish the communication connection of the USB interface due to the path attenuation during the transmission of the DP/DM signal, which finally leads to the disconnection of the car and the machine. even.

The car machine Bluetooth can send the car machine disconnection signal to the mobile phone Bluetooth, and the mobile phone Bluetooth will feed back to the application processor after receiving the car machine disconnection signal.

The mobile phone and the vehicle system perform normal data transmission, and the application processor performs data output based on the original signal strength configuration parameters of the signal adjustment module. The on-board display can display the normal communication connection between the car-machine system and the mobile phone through the USB data cable.

When the communication connection corresponding to the USB interface is in a communication disconnection state, the vehicle-machine system generates a vehicle-machine disconnection signal. It should be noted that the disconnection of the car and the machine is because the signal strength of the DP/DM signal does not meet the signal strength required to establish the communication connection of the USB interface due to the path attenuation during the transmission of the DP/DM signal, which finally leads to the disconnection of the car and the machine. even.

The wireless signal transmitter in the USB data cable sends the car machine disconnection signal to the wireless signal receiver in the mobile phone, and the wireless signal receiver feeds back the application processor after receiving the car machine disconnection signal.

The application processor determines whether the USB interface is in a plugged state. If the USB interface is not plugged in, the application processor does not perform any processing, and the vehicle display can display that the mobile phone and the vehicle system are not connected through the USB data cable. If the USB interface is in the plug-in state, the application processor controls the Redriver chip or the Retimer chip to adjust the signal strength of the DP/DM signal transmitted by the USB data line to enhance the signal strength of the DP/DM signal until the mobile phone and the car are connected normally. .

After the car-machine and the mobile phone are normally connected through the USB interface and stabilized for a period of time, the application processor saves the dynamically adjusted signal strength configuration parameters, and uses the signal strength configuration parameters in future car-machine connections.
