[0022] In order to at least partially solve the above problems and one or more of other potential problems, the embodiments of the present disclosure provide a remote control troubleshooting method for vehicle faults, such as Figure 1 As shown, the following steps are included:

[0023] The cloud receives the remote control request instruction from the console and sends the remote control request instruction to the control unit of the vehicle to be checked, so that the vehicle screen displays a notification information about whether the remote control operation is authorized. Specifically, an account management unit is set in the cloud, and the account management unit stores the accounts of after-sales personnel and the permissions corresponding to each account, so that after-sales personnel with remote control operation permissions log in to the car company's cloud, input the VIN number of the vehicle to be checked to the web terminal of the car company's cloud through the console, and send a remote control request instruction to the control unit of the vehicle. The control unit of the vehicle stores a remote control service program. When the control unit of the vehicle receives the remote control request instruction, a window with notification information about whether the remote control operation is authorized will pop up on the vehicle screen. The owner can authorize the remote control operation by clicking "Agree" in the window, or end the remote control request by clicking "Reject" in the window.

[0024] The cloud receives an instruction from the vehicle's control unit on whether to agree to authorize the remote control operation; when receiving an instruction from the vehicle's control unit on whether to agree to authorize the remote control operation, the cloud receives the video signal and audio signal about the captured vehicle screen from the vehicle's control unit in real time, and sends the video signal and audio signal about the vehicle screen to the display screen in real time, so that the display screen displays the video signal and audio signal about the vehicle screen in real time. Specifically, when the vehicle's control unit receives an instruction to agree or refuse to authorize the remote control operation from the vehicle screen, it will send the instruction to agree or refuse to authorize the remote control operation to the cloud. When the vehicle's control unit receives an instruction to agree to authorize the remote control operation from the vehicle screen, the vehicle's control unit captures the video and audio on the screen in real time and processes them into corresponding video signals and audio signals and sends them to the cloud. More specifically, the vehicle's control unit captures the video and audio on the screen in real time, and encodes the captured video and audio in real time. Preferably, the encoding protocol for video compression is H.264 / H.265 / AV1, the video GOP range is 1 to 2, and the encoding protocol for audio compression is AAC / Opus, the audio frame is no more than 20ms, and the encoded video signal and audio signal are sent to the cloud in real time. The cloud decodes the received video signal and audio signal in real time, and sends the decoded video signal and audio signal to the display screen for real-time display and playback, thereby realizing picture synchronization between the vehicle screen and the display screen.

[0025] In a preferred embodiment, when the cloud receives a video signal about a captured vehicle screen from the vehicle's control unit, it searches for and locates sensitive information in each frame of video, where the sensitive information includes the owner's nickname, mobile phone number, identity information, location information, video collection information, music collection information, and radio station collection information; based on the location of the sensitive information in each frame of video, the sensitive information in each frame of video is masked; when sending the video signal about the vehicle screen to the display screen, a video signal with masked sensitive information is sent, so that the display screen displays the video signal about the vehicle screen with its sensitive information masked.

[0026] The cloud receives control instructions from the console and sends them to the vehicle's control unit, allowing the vehicle's control unit to determine whether the control instructions are executed based on the scope of remote control operation authority, and display the execution information that can be displayed on the vehicle screen on the vehicle screen during the execution of the control instructions. Specifically, after-sales personnel will perform remote control operations based on the fault information reported by the owner, input control instructions to the cloud through the console, and the cloud will send the received control instructions to the vehicle's control unit. The vehicle's control unit stores the scope of remote control operation authority. For example, pictures, audio, video, mobile phone numbers, etc. stored by the user cannot be accessed through remote control operations. The vehicle's control unit determines whether the control instructions are executed based on the scope of remote control operation authority, and display the execution information that can be displayed on the vehicle screen on the vehicle screen during the execution of the control instructions. After-sales personnel directly observe the vehicle's response to the control instructions through a display screen synchronized with the vehicle screen. Based on the response results, after-sales personnel continue to issue control instructions to troubleshoot the fault.

[0027] When the vehicle is executing certain control instructions, the execution information can be directly displayed on the vehicle screen, such as controlling the sound of the speaker, the change of the screen content, etc. The vehicle will display the execution information on the vehicle screen when executing these control instructions, so that after-sales personnel can directly observe the response results through the display screen synchronized with the vehicle screen; when the vehicle is executing certain control instructions, the execution information cannot be displayed on the vehicle screen, such as running the antenna self-test, the camera self-test routine, the USS radar self-test routine, etc. When the vehicle is executing these control instructions, the execution information that cannot be displayed on the vehicle screen is fed back to the vehicle's control unit in real time. The cloud receives the execution information from the vehicle's control unit in real time, and sends the execution information to the display screen in real time, so that the display screen displays according to the execution information in real time, and the after-sales personnel make judgments based on the execution information displayed on the display screen. The vehicle's response result; for some inspections, although the execution information can be displayed on the vehicle screen, when the picture displayed on the display screen synchronized with the vehicle screen is not enough to analyze the cause, the after-sales staff inputs the log printing control instruction to the cloud through the console, and the cloud sends the log printing instruction to the vehicle's control unit, so that the vehicle's control unit executes the log printing and uploads the log to the cloud storage after the log printing is completed; the cloud receives the download log instruction from the console, downloads the log from the storage according to the download log instruction, and sends the downloaded log to the display screen for display. The after-sales staff analyzes the displayed log. When one type of log is not sufficient for analysis, the after-sales staff can issue multiple log printing instructions. When multiple log printing instructions are all executed, the after-sales staff can conduct a comprehensive analysis of the log.

[0028] The cloud receives the fault elimination instruction from the console and sends it to the vehicle's control unit, causing the vehicle to execute the fault elimination instruction to eliminate the fault. Through the above steps, after-sales personnel may discover the cause and solution of the fault during the troubleshooting process. After-sales personnel input the fault elimination instruction to the cloud through the console. The cloud sends the fault elimination instruction to the vehicle's control unit, and the vehicle operates according to the fault elimination instruction. When the fault is eliminated, the cloud receives the remote control end instruction from the console and sends it to the vehicle's control unit, causing the screen to display a remote control end reminder, such as reminding the user that the remote control operation has ended and reminding the user that the remote control service will be completely exited after powering on again, without any information security risks. If after-sales personnel discover the cause of the fault during the troubleshooting process but are unable to eliminate the fault, the cloud receives the repair suggestion instruction from the console and sends it to the vehicle's control unit, causing the screen to display the repair suggestion. For example, if the after-sales personnel discover that the fault is caused by the software, they will inform the user of the repair plan and temporary usage suggestions. If they discover that the fault is caused by the hardware, they will recommend that the user repair or replace the part.

[0029] In a preferred embodiment, the present application supports cross-domain remote control troubleshooting. Specifically, the method of the present application also includes the following steps: the cloud receives a cross-domain remote control request instruction from the console, and sends the cross-domain remote control request to the control unit of the vehicle, so that the vehicle screen displays a notification message indicating whether the cross-domain remote control is authorized; the cloud receives an instruction from the control unit of the vehicle indicating whether to agree to authorize the cross-domain remote control operation; when receiving an instruction from the control unit of the vehicle indicating whether to agree to authorize the cross-domain remote control operation, the cloud receives a cross-domain control instruction from the console and sends the cross-domain control instruction to the control unit of the vehicle, so that the control unit of the vehicle determines whether to execute the cross-domain control instruction according to the scope of remote control operation authority, and provides real-time feedback of cross-domain information during the execution of the cross-domain control instruction; the cloud receives cross-domain information from the control unit of the vehicle in real time, and sends the cross-domain information to the display screen in real time, so that the display screen displays the cross-domain information in real time. The cross-domain information can be displayed in the form of text description combined with pictures, wherein the cross-domain information includes power domain control information and body domain control information, the power domain control information includes battery information, motor information, and charging information, and the body domain control information includes four-door information and anti-theft information.

[0030] In a preferred embodiment, the method of the present application further includes the following steps: the cloud starts timing when it receives the instruction to agree to the authorization, and when the timing reaches a preset time threshold, sends a remote control disconnection instruction to the vehicle's control unit, so that the remote control operation of the vehicle is stopped; the cloud re-sends the remote control request instruction to the vehicle's control unit, so that the vehicle screen re-displays the notification information of whether the remote control operation is authorized; the cloud re-receives the instruction of whether to agree to authorize the remote control operation from the vehicle's control unit; when the instruction of agreeing to authorize the remote control operation is re-received from the vehicle's control unit, the remote control operation of the vehicle is resumed. Preferably, the vehicle's control unit has a forced exit remote control function, and the owner can input a forced exit remote control instruction through the vehicle screen. The vehicle's control unit sends the received forced exit remote control instruction to the cloud, and the cloud receives the forced exit remote control instruction from the vehicle's control unit, so that the remote control operation of the vehicle is stopped.
