[0030] The present application provides a method, apparatus, device and storage medium for determining USB parameters, which can improve the probability of successfully establishing a USB connection between an electronic device and a vehicle device, as well as the reliability of the USB connection between the electronic device and the vehicle device.

[0031] In order to make the technical personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, they should all fall within the scope of protection of the present application.

[0032] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0033] "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or plural.

[0034] In the embodiments of the present application, the electronic device may include a general handheld screen electronic device, such as a mobile phone, a smart phone, a portable terminal, a terminal, a personal digital assistant (PDA), a portable multimedia player (Personal Media Player, PMP) device, a laptop computer, a notebook (Note Pad), a wireless broadband (Wireless Broadband, Wibro) terminal, a tablet computer (Personal Computer, PC) and a smart PC, etc.

[0035] Electronic devices may also include wearable devices. Wearable devices are portable electronic devices that can be worn directly on the user or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but can also achieve powerful intelligent functions through software support, data interaction, and cloud server interaction, such as: computing function, positioning function, and alarm function. They can also be connected to mobile phones and various terminals. Wearable devices may include but are not limited to watches supported by the wrist (such as watches, wrists, etc.), shoes supported by the feet (such as shoes, socks, or other products worn on the legs), glasses supported by the head (such as glasses, helmets, headbands, etc.), as well as smart clothing, school bags, crutches, accessories and other non-mainstream product forms.

[0036] The interconnection between electronic devices and vehicle-mounted devices is an important manifestation of the development of modern automobile intelligence. It can realize seamless connection between electronic devices and vehicles. For example, after the electronic devices are interconnected with vehicle-mounted devices, the navigation application on the electronic devices can be mapped to the display screen of the vehicle-mounted devices, providing the driver with a clear and convenient navigation experience; for another example, after the electronic devices are interconnected with vehicle-mounted devices, the music on the electronic devices can be transmitted to the vehicle-mounted devices, and the driver can control the playback of the music by operating the display screen of the vehicle-mounted devices or voice, which enhances the driver's entertainment experience during driving; for another example, after the electronic devices are interconnected with vehicle-mounted devices, the video streaming media or games on the electronic devices can be mapped to the vehicle-mounted devices, and the driver can control the playback of the video streaming media or the game by operating the vehicle-mounted devices, providing the driver with more entertainment options. It can be seen that the interconnection between electronic devices and vehicle-mounted devices can provide drivers with a more convenient and intelligent driving experience.

[0037] In the related art, the interconnection method between the electronic device and the vehicle device can usually be a USB connection, such as Figure 1 As shown. Figure 1 In the embodiment, the electronic device 10 and the vehicle device 21 of the vehicle 20 are connected via a USB cable, one end of the USB cable is connected to the USB interface of the electronic device 10, and the other end of the USB cable is connected to the USB interface of the vehicle device 21. However, in practice, it is found that when the electronic device 10 is connected to the vehicle device 21 via USB, the USB connection between the electronic device 10 and the vehicle device 21 often fails due to USB compatibility issues, affecting the reliability of the USB connection between the two.

[0038] To solve this problem, the embodiment of the present application discloses a method, device, equipment and storage medium for determining USB parameters, which can improve the reliability of the USB connection between the electronic device 10 and the vehicle-mounted device 21. Specifically, the electronic device 10 obtains the target vehicle model information of the vehicle 20, determines the target USB parameters according to the target vehicle model information, and then performs a USB connection with the vehicle-mounted device 21 based on the determined target USB parameters. Since the target USB parameters are determined based on the vehicle model information of the vehicle 20, the electronic device 10 performs a USB connection with the vehicle-mounted device 21 based on the target USB parameters, which can greatly improve the USB compatibility between the electronic device 10 and the vehicle-mounted device 21, thereby improving the probability of successfully establishing a USB connection between the electronic device 10 and the vehicle-mounted device 21, as well as the reliability of the USB connection between the electronic device 10 and the vehicle-mounted device 21.

[0039] The following describes the method for determining USB parameters disclosed in the embodiment of the present application in conjunction with specific implementation methods.

[0040] See also Figure 2 , Figure 2 FIG. 1 is a flowchart of a method for determining USB parameters disclosed in an embodiment of the present application. Figure 2 The method for determining USB parameters shown may include the following steps:

[0041] 201. The electronic device obtains target vehicle model information of the vehicle.

[0042] In the embodiment of the present application, the target vehicle model information can be used to identify the vehicle model, and the target vehicle model information can include the brand and model name of the vehicle. Among them, the model name can usually intuitively reflect the vehicle's market positioning, functional characteristics and configuration level and other information. The vehicle's market positioning is used to indicate the vehicle's positioning in the market, such as luxury, economy, sports, off-road or home use, etc. The vehicle's functional characteristics are used to indicate the main functions of the vehicle, such as automatic driving or long endurance, etc. The vehicle's configuration level is used to indicate the level of the vehicle's configuration, such as high-end configuration or basic configuration, etc.

[0043] In some embodiments, before the electronic device obtains the target vehicle model information of the vehicle, the electronic device may also detect a target operation, and in response to the target operation, obtain the target vehicle model information of the vehicle; wherein the target operation refers to an operation for triggering the electronic device to establish a USB connection with the vehicle's on-board device. When the electronic device detects the target operation, it indicates that the user wants the electronic device to establish a USB connection with the vehicle's on-board device, and the target vehicle model information of the vehicle may be obtained, and a USB connection may be established with the on-board device based on the target USB parameters corresponding to the target vehicle model information.

[0044] The target operation may include but is not limited to at least one of the following: voice operation, gesture operation, and touch operation. For example, the voice operation may be an audio such as "connect to the vehicle computer" or "connect to the vehicle computer via USB" input by the user. The gesture operation may be an operation such as the user shaking the electronic device left or right or forward and backward, or the user drawing a circle on the display screen of the electronic device. The touch operation may be a virtual button touched by the user to trigger the electronic device to establish a connection with the vehicle computer.

[0045] In some embodiments, before the electronic device obtains the target vehicle model information of the vehicle, the electronic device may also determine whether it is a vehicle-machine interconnection scenario, and if so, obtain the target vehicle model information of the vehicle.

[0046] In the embodiment of the present application, the electronic device may determine whether it is in the vehicle-machine interconnection scenario in the following ways, but is not limited to:

[0047] The electronic device determines whether the electronic device has established a near field communication connection with the vehicle, and if so, determines that it is in a vehicle-machine interconnection scenario;

[0048] or,

[0049] The electronic device detects whether a second control operation is performed on the vehicle. If so, it is determined to be in a vehicle-machine interconnection scenario; wherein the second control operation may include but is not limited to any of the following: remote start operation, remote unlocking operation, remote window opening operation, and remote vehicle search operation, etc.

[0050] It should be noted that the premise that the electronic device can perform the second control operation on the vehicle may be that the electronic device and the vehicle are bound in advance, and both the electronic device and the vehicle equipment are running a remote control application. It can be understood that the electronic device performs the second control operation on the vehicle through the remote control application.

[0051] In an embodiment of the present application, when the electronic device establishes a near-field communication connection with the vehicle, or when performing a second control operation on the vehicle, it indicates that the probability that the user will use the vehicle is high. Similarly, the probability that the user wants to interconnect the electronic device with the vehicle's on-board equipment is also high. The target vehicle model information of the vehicle can be obtained, and based on the target USB parameters corresponding to the target vehicle model information, a USB connection can be established with the on-board equipment.

[0052] In an embodiment of the present application, the vehicle's on-board equipment may only support USB connection, or the vehicle's on-board equipment may not only support USB connection but also support wireless connection (for example, Bluetooth connection or WiFi connection, etc.), which is not limited in the embodiment of the present application.

[0053] In an embodiment of the present application, when the vehicle's on-board equipment supports not only USB connection but also wireless connection, if the electronic device is determined to be in a vehicle-machine interconnection scenario, the electronic device also needs to determine whether to establish a USB connection with the on-board equipment. If so, obtain the target vehicle model information of the vehicle.

[0054] In some embodiments, the electronic device determines whether to establish a USB connection with the vehicle-mounted device by detecting the current power level of the electronic device. If the current power level is less than or equal to a power threshold, it indicates that the electronic device is likely to establish a USB connection with the vehicle-mounted device. In this case, the target vehicle model information of the vehicle can be obtained.

[0055] The power threshold may be pre-set in the electronic device, and the power threshold may be 30%, 50%, etc., which is not limited in the embodiment of the present application.

[0056] In some embodiments, the electronic device determines whether to establish a USB connection with the vehicle device by obtaining historical connection data, and when the historical connection data indicates that the electronic device has established a USB connection with the vehicle device the most times, it indicates that the user is accustomed to establishing a USB connection between the electronic device and the vehicle device, and the target vehicle model information of the vehicle is obtained.

[0057] Among them, the historical connection data records the connection mode of each electronic device and the vehicle device. The historical connection data can record the connection mode of each electronic device and the vehicle device in the past week, the past month or the past quarter, which is not limited in the embodiment of the present application.

[0058] It should be noted that in the vehicle-computer interconnection scenario, electronic devices can more accurately identify scenarios in which electronic devices may establish USB connections with vehicle-computer devices by detecting power levels or analyzing historical connection data. On this basis, obtaining the target vehicle model information of the vehicle is conducive to ensuring the reliability of subsequent USB connections.

[0059] 202. The electronic device determines target USB parameters according to the target vehicle model information.

[0060] The target USB parameters may refer to USB parameters adapted to the target vehicle model information of the vehicle. The electronic device uses the target USB parameters to establish a USB connection with the vehicle's on-board equipment with higher reliability, and there will be no USB connection failure or the probability of USB connection failure is extremely low.

[0061] In the embodiment of the present application, the type of the target USB parameter may include but is not limited to at least one of the following: USB eye diagram parameters, electrical characteristic parameters and data output performance parameters. Among them, the USB eye diagram parameters may include parameters such as eye diagram opening width, eye diagram slope, horizontal bandwidth of the shadow part of the left and right corners of the eye diagram, and decision threshold level. The electrical characteristic parameters may include but are not limited to any of the following: signal level parameters, current parameters and voltage parameters. The data output performance parameters may include data transmission rate and / or encoding and decoding capabilities.

[0062] It should be noted that the USB eye diagram parameters, electrical characteristic parameters and data output performance parameters can all affect the signal quality of the electronic device and the vehicle device when connected via USB, that is, affect the USB compatibility of the electronic device and the vehicle device. The following embodiments are mainly introduced by taking the target USB parameter as the USB eye diagram parameter as an example.

[0063] In some embodiments, the electronic device or server may pre-store the binding relationship between USB parameters and vehicle model information, that is, the electronic device or server may store at least one set of USB parameters and the vehicle model information bound to each set of USB parameters. Based on this, the electronic device may determine the target USB parameters according to the target vehicle model information in the following ways, including but not limited to:

[0064] In the case where the binding relationship between the USB parameters and the vehicle model information is stored in the electronic device, the electronic device may determine a set of USB parameters bound to the target vehicle model information from among the multiple sets of USB parameters as the target USB parameters;

[0065] When the binding relationship between USB parameters and vehicle model information is stored in a server, the electronic device can send the target vehicle model information to the server, so that the server determines a set of USB parameters bound to the target vehicle model information from multiple sets of USB parameters as target USB parameters, and sends the target USB parameters to the electronic device, and the electronic device receives the target USB parameters.

[0066] 203. The electronic device establishes a USB connection with a vehicle computer device based on the target USB parameters.

[0067] After obtaining the target USB parameters, the electronic device can update the USB parameters in the USB driver to the target USB parameters, and establish a USB connection with the vehicle's onboard device based on the updated USB driver.

[0068] Furthermore, before updating the USB driver, the electronic device may first determine whether the USB parameters in the USB driver before the update are different from the target USB parameters. If the USB parameters in the USB driver before the update are different from the target USB parameters, the USB parameters in the USB driver are updated to the target USB parameters.

[0069] In some embodiments, the USB parameters in the USB driver before updating may be default USB parameters, and the target USB parameters may be different from the default USB parameters. Then, the electronic device may establish a USB connection with the vehicle's on-board device based on the target USB parameters, which may include: the electronic device may update the USB parameters in the USB driver from the default USB parameters to the target USB parameters, and establish a USB connection with the vehicle's on-board device based on the updated USB driver.

[0070] The default USB parameters refer to USB parameters that can successfully establish a USB connection with most devices on the market. To facilitate user use, by default, the parameters of the USB driver of the electronic device are the default USB parameters.

[0071] Optionally, at least one set of USB parameters in the binding relationship between the USB parameters and the vehicle type information may include default USB parameters, and therefore, the target USB parameters may also be the default USB parameters.

[0072] When the target USB parameters are consistent with the default USB parameters, that is, when the target USB parameters are the default USB parameters, since the parameters of the USB driver of the electronic device are the default USB parameters, the electronic device does not need to update the USB parameters in the USB driver of the electronic device, and can directly establish a USB connection with the vehicle's on-board device based on the USB driver.

[0073] It can be understood that, when the target USB parameters obtained by the electronic device based on the target vehicle model information are consistent with the default USB parameters, the electronic device does not need to update the USB driver of the electronic device, and directly establishes a USB connection with the vehicle's on-board device based on the current USB driver. However, when the target USB parameters obtained by the electronic device based on the target vehicle model information are different from the default USB parameters, the electronic device needs to update the parameters of the USB driver of the electronic device, and establish a USB connection with the vehicle's on-board device based on the updated USB driver, which is conducive to achieving reliable USB connection between the electronic device and the on-board device.

[0074] By implementing the above method, before establishing a USB connection with the vehicle's on-board equipment, the electronic device first obtains the target vehicle model information of the vehicle, then determines the target USB parameters based on the model information, and finally, based on the determined target USB parameters, establishes a USB connection with the vehicle's on-board equipment. Since the target USB parameters are determined based on the vehicle's model information, the electronic device establishes a USB connection with the on-board equipment based on the target USB parameters, which can greatly improve the USB compatibility between the electronic device and the on-board equipment, thereby improving the probability of successfully establishing a USB connection between the electronic device and the on-board equipment, as well as the reliability of the USB connection between the electronic device and the on-board equipment.

[0075] The following is combined with Figure 3 , an example of obtaining target vehicle model information of a vehicle when an electronic device establishes a near field communication connection with the vehicle is described. It should be noted that the premise for the electronic device to establish a near field communication connection with the vehicle is that the electronic device includes a first near field communication module and the vehicle includes a second near field communication module.

[0076] See also Figure 3 , Figure 3 FIG. 1 is another flowchart of the method for determining USB parameters disclosed in the embodiment of the present application. Figure 3 The method for determining USB parameters shown may include the following steps:

[0077] 301. When a first near field communication module establishes a communication connection with a second near field communication module, the electronic device obtains target vehicle model information sent by the second near field communication module of the vehicle through the first near field communication module.

[0078] It should be noted that the establishment of a communication connection between the first near-field communication module and the second near-field communication module may refer to the establishment of a point-to-point connection between the electronic device and the vehicle based on their respective near-field communication modules, based on which data exchange can be achieved between the electronic device and the vehicle. Specifically, the electronic device may send a vehicle model acquisition request to the vehicle through the first near-field communication module, and when the vehicle receives the vehicle model acquisition request, it responds to the vehicle model acquisition request and sends the target vehicle model information of the vehicle to the electronic device through the second near-field communication module.

[0079] In some embodiments, the trigger condition for the first near-field communication module to establish a communication connection with the second near-field communication module may be that the electronic device unlocks the vehicle door through the first near-field communication module, or that the electronic device starts the vehicle engine through the first near-field communication module, which is not limited in the embodiments of the present application.

[0080] The trigger condition for establishing a communication connection between the first near-field communication module and the second near-field communication module is that the electronic device unlocks the door of the vehicle through the first near-field communication module. The second near-field communication module of the vehicle can be set on the outside of the vehicle. For example, the second near-field communication module of the vehicle can be set below, below, or near the rearview mirror on the driver's door side.

[0081] Correspondingly, before obtaining the target vehicle model information sent by the second near-field communication module of the vehicle through the first near-field communication module, the electronic device can also unlock the door of the vehicle through the first near-field communication module, and when it is determined that the door is unlocked, establish a communication connection with the second near-field communication module through the first near-field communication module.

[0082] In an embodiment of the present application, the electronic device may unlock the door of a vehicle through a first near-field communication module by sending an unlock instruction through the first near-field communication module, and the unlock instruction may include an unlock request and device information of the electronic device, so that when the vehicle receives the unlock instruction through the second near-field communication module, the device information of the electronic device is verified, and then, if the verification passes, the door is unlocked and a first indication information is sent to the electronic device indicating that the door is successfully unlocked.

[0083] It should be noted that the electronic device can determine that the vehicle door is unlocked when receiving the first indication information.

[0084] The unlock request may refer to a request for triggering the vehicle to unlock its doors, and the device information of the electronic device may be used to uniquely identify the electronic device.

[0085] In an embodiment of the present application, the device information may include but is not limited to any of the following: a serial number, a Media Access Control Address (MAC) address, a Universally Unique Identifier (UUID), a specific hardware information combination, a unique identifier generated by the system software, and a proprietary hardware identifier, etc.

[0086] It can be understood that when the electronic device successfully unlocks the vehicle door using the first near-field communication module, a communication connection is established with the vehicle through the first near-field communication module, which is beneficial to improving the security of near-field communication between the electronic device and the vehicle.

[0087] The trigger condition for establishing a communication connection between the first near-field communication module and the second near-field communication module is that the electronic device starts the engine of the vehicle through the first near-field communication module. The second near-field communication module of the vehicle can be set inside the vehicle, for example, the second near-field communication module of the vehicle can be set under the dashboard or near the center console.

[0088] Correspondingly, before obtaining the target vehicle model information sent by the second near-field communication module of the vehicle through the first near-field communication module, the electronic device can also start the engine of the vehicle through the first near-field communication module, and when it is determined that the engine of the vehicle is started, establish a communication connection with the second near-field communication module through the first near-field communication module.

[0089] In an embodiment of the present application, the electronic device starts the engine of the vehicle through the first near-field communication module. The electronic device may send an engine start instruction through the first near-field communication module, and the engine start instruction may include an engine start request and device information of the electronic device, so that when the vehicle receives the engine start instruction through the second near-field communication module, the device information of the electronic device is verified, and then, if the verification passes, the engine of the vehicle is started, and a second indication information indicating that the engine start is successful is sent to the electronic device.

[0090] It should be noted that the electronic device can determine that the engine of the vehicle is started when receiving the second indication information.

[0091] In the embodiment of the present application, the engine start request may refer to a request for triggering a vehicle to start the engine of the vehicle. In addition, for the introduction of the device information of the electronic device, please refer to the above description, which will not be repeated here.

[0092] It is understandable that when the electronic device successfully starts the engine of the vehicle using the first near-field communication module, establishing a communication connection with the vehicle through the first near-field communication module is also conducive to improving the security of near-field communication between the electronic device and the vehicle.

[0093] 302. The electronic device determines target USB parameters according to the target vehicle model information.

[0094] In some embodiments, the electronic device determines the target USB parameters based on the target vehicle model information, which may include: the electronic device searches whether there are USB parameters bound to the target vehicle model information; if so, the USB parameters bound to the target vehicle model information are used as the target USB parameters; if not, the default USB parameters are used as the target USB parameters.

[0095] In some embodiments, the electronic device searches for USB parameters bound to the target vehicle model information by searching a local database of the electronic device for USB parameters bound to the target vehicle model information.

[0096] It is understandable that the local database of the electronic device can store at least one vehicle model information and USB parameters bound to each vehicle model information. Based on this, the electronic device can quickly determine the target USB parameters, which is conducive to improving the efficiency of determining the target USB parameters.

[0097] In some embodiments, the electronic device can search for USB parameters bound to the target vehicle model information by sending the target vehicle model information to a server, and then the server searches the database of the server for USB parameters bound to the target vehicle model information.

[0098] It can be understood that the server's database can store at least one vehicle model information and USB parameters bound to each vehicle model information. Based on this, the electronic device only needs to send the target vehicle model information to the server, and the server will search for the USB bound to the target vehicle model information. This is not only beneficial to reducing the storage pressure of the electronic device, but also beneficial to reducing the device power consumption of the electronic device.

[0099] It should be noted that the USB connection between the electronic device and the vehicle device shown in steps 301-303 is not the first connection. The electronic device can successfully establish a USB connection with the vehicle device based on the target USB parameters (USB parameters bound to the target vehicle model information or default USB parameters).

[0100] In some embodiments, the USB parameter bound to the target vehicle model information may be selected from at least one candidate USB parameter by the electronic device during the first USB connection with the vehicle device.

[0101] In addition, for the explanation of the default USB parameters, please refer to the above description, which will not be repeated here.

[0102] It can be understood that when the electronic device is making a non-first USB connection with the vehicle device, the electronic device first searches for the USB parameters bound to the target vehicle model information. If found, the USB parameters bound to the target vehicle model information are directly used as the target USB parameters. Otherwise, the default USB parameters are used as the target USB parameters, which is conducive to improving the efficiency of determining the USB parameters, thereby improving the efficiency of establishing USB between the electronic device and the vehicle device.

[0103] The following introduces the process of the first USB connection between the electronic device and the vehicle device. The default USB parameters and at least one alternative USB parameter are pre-stored in the electronic device. The electronic device first establishes a USB connection with the vehicle device based on the default USB parameters, and if the USB connection with the vehicle device fails, the electronic device obtains the input vehicle model information, and establishes a USB connection with the vehicle device based on the first alternative USB parameter. If the USB connection with the vehicle device is successfully established, the first alternative USB parameter is bound to the input vehicle model information to improve the efficiency of USB parameter determination when the electronic device subsequently establishes a USB connection with the vehicle device again, which is beneficial to improving the connection efficiency when the electronic device subsequently establishes a USB connection with the vehicle device again.

[0104] For the introduction of the default USB parameters, please refer to the above description, which will not be repeated here. The first candidate USB parameter is one of the at least one candidate USB parameter.

[0105] It should be noted that if the electronic device fails to successfully establish a USB connection with the vehicle device based on the first alternative USB parameter, it continues to switch to other alternative USB parameters to establish a USB connection with the vehicle device until a USB connection is successfully established with the vehicle device.

[0106] In some embodiments, when the electronic device fails to establish a USB connection with the vehicle device based on default USB parameters, the electronic device may also display a vehicle model selection interface, which may include at least one vehicle model information; correspondingly, the electronic device obtains input vehicle model information may refer to the electronic device detecting the vehicle model information selected by the user from the vehicle model selection interface.

[0107] In some embodiments, the vehicle model selection interface may further include a control for triggering switching of USB parameters, and the user may switch the alternative USB parameters by touching the control.

[0108] For example, the diagram of the vehicle model selection interface can be found in the following Figure 4A ,like Figure 4A The vehicle model selection interface shown may display various vehicle model information and a control 400 for triggering switching of USB parameters.

[0109] In the embodiment of the present application, after displaying the vehicle model selection interface, the electronic device can also load and initialize a USB parameter configuration file, wherein the USB parameter configuration file may include the above-mentioned at least one alternative USB parameter, and the format of the USB parameter configuration file may be a lightweight data exchange (JavaScript Object Notation, json) format.

[0110] In some embodiments, after binding the first alternative USB parameter with the input vehicle model information, the electronic device may also store the first alternative USB parameter and the input vehicle model information in a local database of the electronic device in association with each other, or the electronic device may also send the first alternative USB parameter and the input vehicle model information to a server, which in turn stores the first alternative USB parameter and the input vehicle model information in a database of the server in association with each other.

[0111] It should be noted that the at least one alternative USB parameter can be selected from multiple groups of test USB eye diagram parameters, and the multiple groups of test USB eye diagram parameters can include USB eye diagram parameters obtained by performing USB connection tests between the electronic device and the vehicle-mounted devices of a large number of vehicle models. Specifically, the process of performing USB connection tests between the electronic device and the vehicle-mounted device can be to insert the electronic device into the vehicle-mounted device via USB and observe whether the screen projection is successful. If the screen projection fails, use tools such as an oscilloscope and a USB logic analyzer for analysis, modify the USB eye diagram parameters of the electronic device, and insert the USB into the vehicle-mounted device again for connection until the screen projection is successful and the USB eye diagram parameters are saved.

[0112] In some embodiments, the at least one candidate USB parameter may include a boundary eye diagram parameter with the highest tolerance for electronic equipment and vehicle equipment, a USB eye diagram parameter with the highest success rate, and a USB eye diagram parameter with the second highest success rate among multiple sets of test USB eye diagram parameters.

[0113] 303. The electronic device establishes a USB connection with a vehicle computer device based on the target USB parameters.

[0114] It should be noted that for a detailed description of step 303, reference may be made to the above description of step 203, which will not be repeated here.

[0115] In some embodiments, after step 303, when the target USB parameters are USB parameters bound to the target vehicle model information, the electronic device can also switch the parameters in the updated USB driver from the target USB parameters to the default USB parameters when the vehicle is disconnected from the computer, which is beneficial to reduce the error probability of the electronic device when establishing USB with other devices later.

[0116] In some embodiments, the electronic device may determine that the electronic device is in a vehicle-machine disconnection scenario in the following three ways, including but not limited to:

[0117] Method 1: When the electronic device detects that the USB connection between the electronic device and the vehicle device is disconnected, the electronic device determines that the electronic device is in a vehicle-machine disconnection scenario.

[0118] The way in which the electronic device detects whether the USB connection with the vehicle device is disconnected may include but is not limited to at least one of the following: VBus voltage detection, D+ / D- signal detection, and third-party tools.

[0119] It can be understood that after the electronic device establishes a USB connection with the vehicle device, if the electronic device disconnects the USB connection with the vehicle device, it means that there is a high probability that the electronic device is no longer connected to the vehicle device. In this case, automatically switching the parameters in the USB driver back to the default USB parameters can more accurately identify the scenario in which the electronic device may disconnect from the vehicle device via USB. On this basis, automatically switching the parameters in the USB driver back to the default USB parameters is conducive to improving the efficiency of establishing subsequent USB connections with other devices.

[0120] Method 2: The electronic device locks the door of the vehicle through the first near-field communication module, and when it is determined that the door is locked, determines that the vehicle is in a disconnected scenario.

[0121] It should be noted that, for an introduction to the electronic device locking the vehicle doors through the first near-field communication module, please refer to the above-mentioned description of the electronic device unlocking the vehicle doors through the first near-field communication module, which will not be repeated here.

[0122] It can be understood that after the electronic device establishes a USB connection with the vehicle device, if the electronic device successfully locks the vehicle door through the first near-field communication module, it means that the probability of the vehicle being disconnected is low, and the parameters in the USB driver are automatically switched back to the default USB parameters. This can more accurately identify scenarios in which the electronic device may be disconnected from the vehicle device via the USB connection. On this basis, the parameters in the USB driver are automatically switched back to the default USB parameters, which is conducive to improving the efficiency of establishing subsequent USB connections with other devices.

[0123] Method 3: When the electronic device detects a first control operation on the vehicle, it is determined that the vehicle is in a vehicle-computer disconnection scenario; wherein the first control operation may include but is not limited to: a remote locking operation or a remote shutdown operation, etc.

[0124] It should be noted that the premise for the electronic device to perform the first control operation on the vehicle may be the same as the premise for the electronic device to perform the second control operation on the vehicle, and will not be repeated here.

[0125] It can be understood that after the electronic device establishes a USB connection with the vehicle device, if the electronic device performs the first control operation on the vehicle, it means that the probability of the vehicle is low, then the parameters in the USB driver are automatically switched back to the default USB parameters, which can more accurately identify the scenario where the electronic device may disconnect the USB connection with the vehicle device. On this basis, the parameters in the USB driver are automatically switched back to the default USB parameters, which is conducive to improving the efficiency of establishing subsequent USB connections with other devices.

[0126] For ease of understanding, the following combination Figure 4B , the process of determining and resetting USB eye diagram parameters by the electronic device through the first near field communication module is described.

[0127] 401. The electronic device unlocks a door of a vehicle through a first near-field communication module.

[0128] It should be noted that step 401 is initiated when the user gets on the bus.

[0130] 403. The electronic device searches for information about the target vehicle model and finds whether the target vehicle model information is bound to a USB eye diagram parameter.

[0131] If the judgment result of step 403 is yes, then continue to step 404, otherwise, execute step 406.

[0132] 404. The electronic device updates the parameters in the USB driver to be the USB eye diagram parameters bound to the target vehicle model information.

[0133] 405. The electronic device locks the door of the vehicle through the first near field communication module.

[0134] It should be noted that step 405 is initiated when the user gets off the vehicle.

[0135] 406. The electronic device uses default USB eye diagram parameters.

[0136] By implementing Figure 3In the method shown, before establishing a USB connection with the vehicle's on-board device, the electronic device first obtains the target vehicle model information of the vehicle, then determines the target USB parameters based on the model information, and finally, based on the determined target USB parameters, establishes a USB connection with the vehicle's on-board device. Since the target USB parameters are determined based on the vehicle's model information, the electronic device establishes a USB connection with the on-board device based on the target USB parameters, which can greatly improve the USB compatibility of the electronic device and the on-board device, thereby improving the probability of successfully establishing a USB connection between the electronic device and the on-board device, as well as the reliability of the USB connection between the electronic device and the on-board device.

[0137] In addition, when the first near-field communication module establishes a communication connection with the second near-field communication module, the electronic device can obtain the target vehicle model information sent by the second near-field communication module of the vehicle in real time through the first near-field communication module, thereby ensuring the accuracy of the target vehicle model information.

[0138] The following is combined with Figure 5 , an example of an electronic device obtaining target vehicle model information of a vehicle when performing a second control operation on the vehicle is introduced.

[0142] It should be noted that, regarding the prerequisites for the electronic device to perform the second control operation on the vehicle, reference can be made to the description in the above embodiment and will not be repeated here.

[0143] It is understandable that after the electronic device is successfully bound to the vehicle, the target vehicle model information of the vehicle can be stored in the local storage space of the electronic device or in the server, which is not limited in the embodiments of the present application.

[0144] In a case where the target vehicle model information of the vehicle is stored in a local storage space of the electronic device, the electronic device obtaining the target vehicle model information of the vehicle may refer to the electronic device obtaining the target vehicle model information of the vehicle from the local storage space of the electronic device.

[0145] In a case where the target vehicle model information of the vehicle is stored in a server, the electronic device obtaining the target vehicle model information of the vehicle may refer to the electronic device requesting the target vehicle model information of the vehicle from the server.

[0146] 502. The electronic device determines target USB parameters according to the target vehicle model information.

[0147] 503. The electronic device establishes a USB connection with a vehicle computer device based on the target USB parameters.

[0148] It should be noted that, for the introduction of step 502-step 503, reference may be made to the above description of step 302-step 303, which will not be repeated here.

[0149] By implementing Figure 5 In the method shown, before establishing a USB connection with the vehicle's on-board device, the electronic device first obtains the target vehicle model information of the vehicle, then determines the target USB parameters based on the model information, and finally, based on the determined target USB parameters, establishes a USB connection with the vehicle's on-board device. Since the target USB parameters are determined based on the vehicle's model information, the electronic device establishes a USB connection with the on-board device based on the target USB parameters, which can greatly improve the USB compatibility of the electronic device and the on-board device, thereby improving the probability of successfully establishing a USB connection between the electronic device and the on-board device, as well as the reliability of the USB connection between the electronic device and the on-board device.

[0150] In addition, when the electronic device detects that the second control operation is performed on the vehicle, it obtains the target vehicle model information of the vehicle, realizes the advance determination of USB parameters, and further improves the efficiency of establishing a USB connection between the electronic device and the vehicle device.
