Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

In the related art, there are two connection modes for realizing interconnection between a vehicle and electronic equipment.

The wired connection is based on a data line, wherein the data line can be a Micro USB interface data line, a Type-C interface data line or a Lighting interface data line and the like; another is wireless connection based on bluetooth, wireless local area network (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 (UWB) technology.

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, a car machine and the like. The performance of a functional module related to the data line in the electronic equipment is relatively stable, and the influence on the wired signal transmitted by the data line is small; different types of data lines have different lengths and larger performance difference, and have larger influence on wired signals transmitted by the data lines; because the layout position of the main control board is limited, an extension line corresponding to a wired interface is added in the vehicle, and the extension line has a large influence on wired signals transmitted by the data line. The problem of disconnection of communication connection due to poor quality of the existing line signal occurs regardless of the data line or the extension line.

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

The communication control method can be applied to the electronic equipment, and can be specifically executed by hardware or software in the electronic equipment. The electronic device in the embodiment of the present application includes, but is not limited to, mobile communication devices such as a mobile phone, a tablet computer, a camera, and a wearable device, and the communication control method provided in the embodiment of the present application is described below by taking the electronic device as an execution body as an example.

Fig. 1 is a schematic diagram of a communication control system of a communication control method according to an embodiment of the present application. The communication control method provided by the embodiment of the application can be applied to a communication control system shown in fig. 1.

As shown in fig. 1, a communication control system according to an 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; the electronic device 100 may include, among other things, an application processor 110 and a signal conditioning module 120.

In actual implementation, the electronic device 100 may be connected to the vehicle 130 by a data line. It will be appreciated that the two ends of the data line are also provided with wired interfaces, and the electronic device 100 and the vehicle 130 are provided with interfaces for connecting with the wired interfaces of the data line.

It should be noted that, the car machine refers to the abbreviation of the car information entertainment product installed in the car, the car machine can realize the information communication between the user terminal and the car, between the car and the outside or between the car and the car functionally, and the car machine is mostly installed in the car center console at present.

After the electronic device 100 and the car machine 130 in the embodiment of the present application are connected in a wired manner, a communication connection corresponding to the wired interface may be established based on a protocol such as USB2.0 or USB 3.2.

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

When the amplitude of a signal received by electronic equipment or a vehicle machine is smaller than a threshold value set by the Squelch parameter, the received signal is judged to be an interference signal, decoding is not performed, the interference signal is filtered, the electronic equipment cannot receive the signal, namely, data transmission is not performed, and further the problem that the signal is disconnected when a user performs the function of the vehicle networking in a wired mode is caused, so that the experience of the user is affected. Similarly, when the signal amplitude received by the electronic equipment is larger than the threshold value set by the HS_disconnect parameter, the electronic equipment is judged to be disconnected from communication, and the problem of signal disconnection when a user performs the function of the internet of vehicles in a wired mode is also caused, so that the experience of the user is affected.

Fig. 2 is a schematic flow chart of a communication control method according to an embodiment of the present application. As shown in fig. 2, the communication control method includes:

step 210, determining that the communication connection corresponding to the wired interface is disconnected based on the first signal received by the application processor 110; the first signal is a signal transmitted in the case where the electronic device 100 establishes a wireless connection with the car machine 130;

In step 220, the control signal adjusting module 120 enhances 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 vehicle 130 may be connected by a wired connection through a data line. The data line may be a Lighting data line, a Micro USB interface data line, a Type-C data line, or the like. The types of wired interfaces at both ends of the data line 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 line may be inserted into the electronic device 100, and the other end may be inserted into the car machine 130. The wired interface at one end of the data line is usually a Type-a interface, and is used for being plugged into the vehicle 130; the wired interface at the other end of the data line is connected with the electronic device 100, and taking a mobile phone as an example, the wired interface of the mobile phone can be a Micro USB interface, a Mini USB interface, a Type-B interface, a Lighting interface, a Type-C interface or the like. The types of the wired interfaces at the two ends of the data line can be set according to practical situations, and the application is not particularly limited.

In some scenarios, the user may normally use the vehicle networking function in case the electronic device 100 and the vehicle 130 are wired via a data line. When the automobile passes through a bumpy road section, the automobile body can shake, so that the wired signal transmitted by the data line shakes, and the wired connection has path attenuation, and although the data line still maintains a connection state, the signal strength of the wired signal may not meet the communication connection requirement at this time, so that the electronic device 100 and the automobile machine 130 disconnect the communication connection corresponding to the wired interface.

It should be noted that, in addition to the wired connection through the data line, the electronic device 100 and the vehicle machine 130 may also be connected wirelessly, so that when the communication connection corresponding to the wired interface is disconnected, the electronic device 100 and the vehicle machine 130 may also perform data transmission through the wireless communication connection. For example: a bluetooth connection, zigBee network connection, or wireless fidelity (Wireless Fidelity, wi-Fi) connection, etc. may be made.

When the vehicle machine 130 detects that the communication connection corresponding to the wired interface is in the disconnected state and the electronic device 100 and the vehicle machine 130 have established wireless connection, the vehicle machine 130 may send a first signal to the electronic device 100 through wireless communication, so that the vehicle machine 130 may timely feed back to the electronic device 100 that the vehicle machine 130 is in the disconnected state.

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

The electronic device 100 may receive the first signal through a function module for receiving a wireless signal, such as a signal receiver or a bluetooth module, and transmit 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 may send a control signal to the signal adjustment module 120, so that the signal adjustment module 120 may be controlled to dynamically adjust the signal strength of the second signal transmitted through the wired interface, and enhance the signal strength of the second signal, so as to achieve the signal strength required by the electronic device 100 and the vehicle 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 particularly limited herein.

The signal adjustment module 120 may be configured based on a signal enhancement chip, which will be described in the following embodiments. The second signal refers to a differential signal transmitted based on a wired interface, and the differential signal may include a Data Minus (DM) signal and a Data Positive (DP) signal.

The signal adjustment module 120 in the embodiment of the present application can monitor signals transmitted by data lines with different lengths and different types in real time, and adjust signal strength in real time, so that the application range is wider.

According to the communication control method provided by the embodiment of the application, the connection state of the communication connection corresponding to the wired interface can be determined in time by applying the first signal received by the processor, and the signal intensity of the second signal transmitted based on the wired interface can be dynamically adjusted by the signal adjusting module according to the connection state in real time, so that the signal intensity of the second signal can be enhanced, the signal intensity of the communication connection corresponding to the wired interface can be established, the disconnection condition is reduced, and the vehicle-mounted experience of a user is improved; in addition, a signal adjusting module is added in the electronic equipment, so that the circuit structure is simple and the cost is low.

In some embodiments, the signal conditioning module 120 includes at least one of: a driver chip or a repeater chip.

In practical implementation, the signal adjustment module 120 may be constructed based on a signal enhancement chip, and the signal enhancement chip may include, but is not limited to, a driver chip and a Retimer chip, and may also be other chips with signal adjustment functions, which are not specifically limited herein.

It should be noted that the driver chip may be a chip that functions as a signal repeater, which may amplify a signal and increase signal quality or signal strength on a high-speed interface. In particular by using techniques such as equalization and pre-emphasis to adjust and correct the loss of the channel signal at the transmitting end and to restore the integrity of the signal at the receiving end.

The Retimer chip is a device that mixes digital and analog signals. The analog signal entering the Retimer chip is restored to a digital signal, and then is changed into an analog signal again to be sent out. It has sensing capability and can fully recover the data signal and re-send. Specifically, an embedded clock in an input signal is extracted through a clock data recovery circuit embedded in the clock data recovery circuit, and data is retransmitted by using a clock signal which is completely unattenuated and deformed so as to form a new copy of an original data signal. The mode that the data is recovered first and then the signal is retransmitted through the serial channel of the Retimer chip can effectively solve the problem of attenuation of the signal intensity.

In the embodiment of the present application, one or more of a driver chip or a Retimer chip may be added to the electronic device 100. The driver chip or the repeater chip can dynamically adjust the signal strength of the second signal transmitted based on the USB interface, so that the vehicle machine 130 and the electronic device 100 can reestablish communication connection corresponding to the USB interface as soon as possible, further, the function of the vehicle networking can be quickly recovered, and the vehicle-mounted experience of a user is improved.

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, the 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, parameters may be configured for different types and lengths of data lines corresponding to different signal strengths.

After the signal adjustment module 120 receives the control signal from the application processor 110, the signal strength configuration parameter of the data line is determined based on the length and the type of the data line, and the signal strength configuration parameter is written into the signal adjustment module 120. And based on the signal strength configuration parameter, adjusting the signal strength of the second signal, and recovering the integrity of the second signal, thereby enhancing the signal strength of the second signal.

According to the communication control method provided by the embodiment of the application, the signal intensity of the second signal can be adjusted in real time through the signal adjusting module, so that the signal intensity of the second signal can be enhanced, and the disconnection condition of the communication connection corresponding to the wired interface is reduced.

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

reestablishing a communication connection corresponding to the wired interface with the vehicle machine 130 when the signal strength of the second signal meets the strength threshold;

and under the condition that the holding time of the communication connection corresponding to the wired interface exceeds a time threshold, the signal strength configuration parameters are saved.

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, so that the electronic device 100 and the vehicle machine 130 may reestablish the communication connection through the wired interface. The intensity threshold may be set based on a USB protocol, or may be set according to a device-related parameter corresponding to the electronic device 100 or the vehicle 130, which is not specifically limited herein.

In the case that the holding time of the communication connection corresponding to the wired interface exceeds the time threshold, it may be considered that the communication connection corresponding to the wired interface tends to be stable, and the application processor 110 further saves the signal strength configuration parameter of the signal adjustment module 120. The time threshold may be determined according to actual requirements, and is not specifically limited herein.

Based on the signal strength configuration parameters of the signal adjustment module 120, the electronic device 100 and the vehicle machine 130 can perform data transmission, and the user can normally use the vehicle networking function through the electronic device 100, for example: a portion of the applications in the electronic device 100 may be projected onto a corresponding display screen of the vehicle 130.

According to the communication control method provided by the embodiment of the application, the signal intensity of the second signal is adjusted through the signal adjustment module, so that the signal intensity of the second signal meets the intensity threshold, after the electronic equipment and the vehicle are stably connected through the wired interface, the dynamically adjusted signal intensity configuration parameters are stored, and the signal intensity configuration parameters are used in the subsequent vehicle-to-vehicle connection, so that the stability of the communication connection is further improved.

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

Judging the insertion state of the wired interface;

in the event that a determination is made that the wired interface is plugged into the truck 130, the control signal adjustment module 120 enhances the signal strength of the second signal.

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

If it is determined that the wired interface is not plugged into the car set 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 car machine 130 may send a prompt message to the electronic device 100 to prompt the user that the data line is in a disconnected state, so as to facilitate reconnection of the data line by the user.

If it is determined that the wired interface is plugged into the car set 130, the application processor 110 may send a control signal to the signal adjustment module 120 to control the signal adjustment module 120 to perform signal enhancement on the signal strength of the second signal.

Fig. 3 is a second schematic diagram of a communication control system of the communication control method according to the embodiment of the present application. The communication control method provided by the embodiment of the application can be applied to a communication control system shown in fig. 3.

The communication control system may include: cell-phone and car machine. The mobile phone and the car phone are connected in a wired way through a USB data line. The handset may include an application processor, handset bluetooth, a signal conditioning module (r driver chip or re timer chip), a USB switch, and an audio switch. The vehicle may include vehicle bluetooth and vehicle systems.

The USB data line is mainly used for connecting a mobile phone with a car phone and is a hardware medium for data transmission; the USB switch may employ DIO5000, where DIO5000 is a high-speed, low-power-consumption, double-pole/double-throw analog switch for switching high-speed USB2.0 signals in handheld devices (such as cell phones, digital cameras and notebook computers, or devices with hubs or controllers); the audio switch may employ an FSA4480, the FSA4480 being a high performance multimedia switch allowing for the transmission of USB2.0 signals, analog audio signals, and analog microphone signals.

The application processor is responsible for the running of a mobile phone software system, the realization of mobile phone terminal functions and the control of peripheral devices, and is a control center of the whole mobile phone.

The mobile phone Bluetooth can be used for receiving signals sent by the vehicle phone Bluetooth, so that whether the wired interface corresponding to the USB data line of the mobile phone is in a communication connection state or not is confirmed.

The driver chip or the repeater chip is used for adjusting the signal intensity of the DP/DM signal transmitted by the USB data line, so as to enhance the signal intensity of the DP/DM signal.

The USB switch can realize the switching of a central processing unit (Central Processing Unit, CPU), a charging micro-control unit (Microcontroller Unit; MCU) and a power management chip.

The audio switch may implement switching of earphone, USB and OTG (On-The-Go) functions. The OTG function is a technology that allows a mobile phone to connect to multiple peripheral devices without transferring a computer.

Fig. 4 is a second flowchart of a communication control method according to an embodiment of the present application. As shown in fig. 4, the communication control method provided in the embodiment of the present application may include:

the USB interface at one end of the USB data line is connected with the mobile phone, and the USB interface at the other end of the USB data line is connected with the vehicle-mounted system. The vehicle-mounted display can display the data line connection information of the mobile phone and the vehicle system.

The mobile phone and the car system perform normal data transmission, and the application processor performs data output based on the original signal strength configuration parameters of the driver chip or the Retimer chip in the signal adjustment module. The vehicle-mounted display can display that the vehicle-mounted system and the mobile phone are in normal communication connection through the USB data line.

And under the condition that the communication connection corresponding to the USB interface is in a communication disconnection state, the vehicle machine system generates a vehicle disconnection signal. It should be noted that, the disconnection of the vehicle is caused by that the signal intensity of the DP/DM signal is not satisfied by the signal intensity required to establish the communication connection of the USB interface due to the attenuation of the path during the transmission process of the DP/DM signal, and finally, the disconnection of the vehicle is caused.

The car machine Bluetooth can send a car disconnection signal to the mobile phone Bluetooth, and the mobile phone Bluetooth receives the car disconnection signal and feeds the car disconnection signal back to the application processor.

The application processor judges whether the USB interface is in an inserted state. If the USB interface is in the non-inserted state, the application processor does not perform any processing, and the vehicle-mounted display can display that the mobile phone and the vehicle system are not in communication connection through the USB interface. If the USB interface is in the inserted state, the application processor controls the driver chip or the timer chip to adjust the signal intensity of the DP/DM signal transmitted by the USB data line so as to enhance the signal intensity of the DP/DM signal until the mobile phone is in normal communication connection with the vehicle.

After the vehicle-mounted device and the mobile phone are normally connected in a communication way through the USB interface and are stable for a period of time, the application processor stores the dynamically adjusted signal strength configuration parameters, and the signal strength configuration parameters are used in the connection of the vehicle-mounted device in the future. After the application processor determines that the vehicle-mounted system reestablishes communication connection through the USB interface, the vehicle networking function can be normally used between the mobile phone and the vehicle-mounted system.

Instead, a wireless signal transmitter is added to the USB data line, and a wireless signal receiver is added to the mobile phone to perform wireless connection.

Fig. 6 is a third flow chart of a communication control method according to an embodiment of the present application. As shown in fig. 6, the communication control method provided in the embodiment of the present application may include:

one end of the USB interface of the USB data line is connected with the mobile phone, and the other end of the USB data line is connected with the car machine system. The vehicle-mounted display can display connection information of the mobile phone and the vehicle system.

The mobile phone and the car 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 vehicle-mounted display can display that the vehicle-mounted system and the mobile phone are in normal communication connection through the USB data line.

The wireless signal transmitter in the USB data line transmits the disconnection signal of the vehicle to the wireless signal receiver in the mobile phone, and the wireless signal receiver receives the disconnection signal of the vehicle and feeds the disconnection signal back to the application processor.

The application processor judges whether the USB interface is in an inserted state. If the USB interface is in an uninstalled state, the application processor does not perform any processing, and the vehicle-mounted display can display that the mobile phone and the vehicle system are not in communication connection through the USB data line. If the USB interface is in the inserted state, the application processor controls the driver chip or the timer chip to adjust the signal intensity of the DP/DM signal transmitted by the USB data line so as to enhance the signal intensity of the DP/DM signal until the mobile phone is in normal communication connection with the vehicle.

According to the communication control method provided by the embodiment of the application, on the basis of guaranteeing the integrity of the vehicle-mounted circuit, the signal parameters are dynamically adjusted in real time by utilizing the internal circuit of the mobile phone, the USB data line and the driver chip or the Retimer chip, so that the situation that the vehicle is disconnected is avoided; the circuit is very simple, the cost is low, and the implementation is easy; the pain point of the disconnection of the user vehicle can be solved, user complaints are reduced, and the vehicle-mounted experience of the user is improved.
