[0035] According to the embodiments of the present invention, an embodiment of a method for monitoring domain controller function testing is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0036] In this embodiment, a method for monitoring domain controller function testing is provided, which can be used in the above-mentioned monitoring system for domain controller function testing.Figure 1 It is a schematic flowchart of a monitoring method for domain controller function testing according to an embodiment of the present invention. As Figure 1 shown, the process includes the following steps:

[0037] Step S101, obtain the scenario information of the target scenario; wherein, the scenario information includes the control device for monitoring the cockpit domain controller and the control strategy for monitoring the cockpit domain controller corresponding to the control device for monitoring the cockpit domain controller, and the target scenario indicates the scenario for performing function testing on the domain controller.

[0038] As can be seen from the above, the target scenario can be a single scenario or a combination of multiple scenarios. Among them, when the target scenario is a single scenario, the target scenario can be any one of a video playback test monitoring scenario, a router signal test monitoring scenario, an Ethernet communication test monitoring scenario, an audio test monitoring scenario, an image recording function test monitoring scenario, a charging function test monitoring scenario, a Bluetooth function test monitoring scenario, and a radar function test monitoring scenario.

[0040] Among them, the number of scenarios in the target scenario can be set manually, that is, it can be determined according to the control device in the above-mentioned monitoring system for domain controller function testing.

[0041] The control strategy for monitoring the cockpit domain controller corresponding to the control device for monitoring the cockpit domain controller can indicate how to control the control device for monitoring the cockpit domain controller to monitor the function testing of the domain controller.

[0042] As an example, the function testing of data transmission of the domain controller can be monitored by transmitting the image data received by the domain controller to a monitoring display screen arranged outside the shielding space.

[0043] As an example, the function testing of audio transmission of the domain controller can be monitored by transmitting the audio signal received by the domain controller to an audio analyzer arranged outside the shielding space.

[0044] Step S102, according to the control strategy, control the control device to monitor the function testing of the domain controller.

[0045] As can be seen from the above content, the control strategy can be adjusted according to different control devices for monitoring the cockpit domain controller. For example, when the control devices for monitoring the cockpit domain controller include control device A1 and control device B1, the control strategy can be C1; when the control devices for monitoring the cockpit domain controller include control device A2 and control device B2, the control strategy can be C2. The specific control strategy will be described in detail below.

[0046] The monitoring method for domain controller function testing provided in this embodiment can cover the function testing of the domain controller through various test monitoring scenarios of the domain controller, so that various functions of the domain controller can be comprehensively and efficiently verified. Whether it is the function verification of hardware modules, such as processors, memories, sensor interfaces, etc., or the correct execution of software functions.

[0047] Please refer to Figure 2 , Figure 2 which is a modular schematic diagram of the monitoring system for domain controller function testing according to an embodiment of the present invention.

[0048] In a possible implementation manner, please refer to Figure 2 , the control devices include a router, a monitoring camera, an in-vehicle display screen, a storage device, a host computer, a monitoring display screen, and an Ethernet parsing box. The router, the monitoring camera, the in-vehicle display screen, the storage device, and the domain controller are arranged in a shielding space. The storage device and the in-vehicle display screen are respectively connected to the domain controller. The domain controller is connected to the Ethernet parsing box through a first optical fiber (i.e., Figure 2 the optical fiber between the domain controller and the Ethernet parsing box in Figure 2 ), and the Ethernet parsing box is communicatively connected to the host computer. The monitoring camera is communicatively connected to the monitoring display screen through a second optical fiber (i.e.,

[0049] Step S201, controlling the domain controller to obtain the first image data of the storage device and sending the first image data to the in-vehicle display screen.

[0050] The shielding space can be Figure 2 the darkroom in Figure 2 . The domain controller can instruct the electronic control unit in the vehicle responsible for a specific functional domain (such as the power domain, the body domain, the chassis domain, etc.). The storage device (such as

[0051] During specific implementation, the domain controller obtains the first image data from the storage device and sends the first image data to the in-vehicle display screen (such as the central control display screen, instrument panel, etc.) for display through a certain communication method (such as Ethernet, CAN bus, etc.).

[0052] As an example, the domain controller can read map data from the storage device and send the map data to the in-vehicle display screen to display the route and navigation information.

[0053] As an example, the domain controller reads the image data containing the urban street map from the hard disk and sends the image data to the central control display screen through Ethernet.

[0054] Step S202, control the monitoring camera to collect the first image data displayed on the in-vehicle display screen and send the first image data to the monitoring display screen through the second optical fiber to monitor the first image data displayed on the in-vehicle display screen.

[0055] The monitoring camera can represent a device for capturing video or images, and can specifically be used for monitoring and recording. Among them, the monitoring camera can be set in a shielded space. The second optical fiber can represent an optical fiber communication line. Specifically, it can be the optical fiber of the optical fiber conversion module. The monitoring display screen can represent a screen for displaying the images or videos captured by the monitoring camera.

[0056] During specific implementation, control the monitoring camera to collect the first image data displayed on the in-vehicle display screen and send these data to the monitoring display screen (such as the screen in the monitoring center) through the second optical fiber.

[0057] As an example, the monitoring camera can capture the navigation information on the in-vehicle display screen and send it to the monitoring center so that the management personnel can monitor the vehicle status in real time.

[0058] Step S203, control the monitoring camera to collect the signal status information of the router and send the signal status information to the monitoring display screen through the second optical fiber.

[0059] The router can represent a device for connecting different networks or network segments, and can specifically be used to provide signals (such as Wifi signals). The signal status information can be information such as the router signal quality and connection status.

[0060] During specific implementation, control the monitoring camera to collect the signal status information of the router (such as signal strength, connection status, etc.) and send this information to the monitoring display screen through the second optical fiber.

[0061] Step S204, monitor the communication status, packet loss rate, and signal quality of the Ethernet communication of the domain controller through the host computer.

[0062] The host computer (i.e., the PC in Figure 2 ) can be a device or system for controlling, monitoring, and managing the slave computer (such as a domain controller). Ethernet communication can represent the network communication protocol. The packet loss rate can represent the proportion of data packets lost during communication. The signal quality can represent the quality indicators such as the strength and stability of the communication signal.

[0063] During specific implementation, the host computer monitors the communication status, packet loss rate, and signal quality of the Ethernet communication of the domain controller.

[0064] It should be noted that the target scenarios that can be achieved by the above steps S201 to S204 are the video playback test monitoring scenario, the router signal test monitoring scenario, and the Ethernet communication test monitoring scenario.

[0065] In a possible implementation, the in-vehicle computer reads the USB flash drive and plays it on the in-vehicle display screen through a deserialization chip. The monitoring camera in the darkroom converts the picture of the in-vehicle display screen in the shielded room to the display screen outside the shielded darkroom through an optical fiber for real-time monitoring. The router is placed in the darkroom through the network cable passing through the wall and is wirelessly interconnected with the in-vehicle computer. The connection status is displayed on the in-vehicle display screen, and then it is displayed on the external monitoring display screen through the monitoring camera in the shielded darkroom, so that the WIFI connection status in the experiment can be monitored. The optical fiber converter is used to mutually PIN with the PC outside the darkroom, and the communication status, packet loss rate, and SQI value of the Ethernet are monitored through the PC host computer.

[0066] The monitoring method for the domain controller function test provided in this embodiment can accurately monitor the image transmission function of the domain controller through the combined application of a monitoring display screen, a monitoring camera, an in-vehicle display screen, and a storage device.

[0067] Meanwhile, by sending the signal status information to the monitoring display screen through the second optical fiber and monitoring the communication status, packet loss rate, and signal quality of the Ethernet communication of the domain controller through the host computer, it is possible to effectively monitor whether there is an abnormality in the Ethernet.

[0068] Please refer to Figure 3 , Figure 3 which is a modular schematic diagram of the monitoring system for the domain controller function test according to the embodiment of the present invention.

[0069] In a possible implementation, please refer to Figure 3 , the control device includes: a monitoring camera, an in-vehicle display screen, a speaker, an audio analyzer, a monitoring display screen, a signal generator, an in-vehicle camera, and a mobile terminal. The monitoring camera, the in-vehicle display screen, the speaker, the monitoring display screen, and the in-vehicle camera are arranged in a shielded space. The monitoring camera is connected through a third optical fiber (i.e., Figure 3Optical fiber conversion between the monitoring camera and the monitoring display screen) and is communicatively connected to the monitoring display screen. The signal generator, vehicle-mounted camera, mobile terminal, vehicle-mounted display screen, and speaker are respectively connected to the domain controller. The speaker is communicatively connected to the audio analyzer through the fourth optical fiber (i.e., Figure 3 Optical fiber conversion between the speaker and the audio analyzer in

[0070] Step S301: Control the signal generator to send radio waves carrying the first audio signal to the domain controller.

[0071] The shielding space can be Figure 3 The darkroom in , that is, the cockpit domain controller requires space during EMC testing. The signal generator can be an instrument that generates variable physical quantities or electrical signals for testing or calibrating the system. Among them, the signal generator can be an FM signal generator. Radio waves can represent electromagnetic waves propagating through space and are specifically used to transmit information.

[0072] In specific implementation, a signal generator is used to generate a radio wave containing a specific audio signal. This radio wave can then be sent to the electronic control unit of the domain controller in the vehicle.

[0073] As an example, the signal generator generates a radio wave containing a sine-wave audio signal, and this signal is sent to the domain controller, which receives and decodes the signal.

[0074] Step S302: Control the domain controller to amplify the first audio signal and then send it to the speaker, so that the speaker sends the amplified first audio signal to the audio analyzer; wherein, the audio analyzer performs analysis and testing based on the amplified first audio signal.

[0075] The audio analyzer can represent an electronic device for measuring and analyzing audio signals. The speaker can be a device that converts electrical signals into sound.

[0076] In specific implementation, after receiving the audio signal in the radio wave, the domain controller amplifies it and then sends the amplified signal to the vehicle's speaker. The speaker outputs the sound signal, and this sound signal is then captured and analyzed by the audio analyzer.

[0077] As an example, the audio signal is amplified and sent to the speaker, and the sound emitted by the speaker can be captured by the audio analyzer, and then parameters such as the frequency response and distortion of the audio system can be measured and analyzed.

[0078] Step S303: Control the domain controller to obtain the second image data sent by the vehicle-mounted camera and send the second image data to the vehicle-mounted display screen.

[0079] The domain controller receives image data from in-vehicle cameras (such as cameras in front of the vehicle), and then sends this image data to the in-vehicle display screen (such as the display screen on the instrument panel or the display screen of the entertainment system).

[0080] Step S304: Control the monitoring camera to collect the second image data displayed on the in-vehicle display screen, and send the second image data to the monitoring display screen through the third optical fiber to monitor the second image data displayed on the in-vehicle display screen.

[0081] In specific implementation, an additional monitoring camera is used to capture the image data on the in-vehicle display screen, and this image data is then sent to the monitoring display screen (such as the monitoring screen in the test room) through an optical fiber.

[0082] Step S305: Control the domain controller to charge the mobile terminal through the interface, collect the charging data through the monitoring camera, and send the charging data to the monitoring display screen through the third optical fiber to monitor the charging data displayed on the in-vehicle display screen.

[0083] The mobile terminal can be a portable electronic device such as a mobile phone or a tablet computer. In specific implementation, the domain controller can provide charging services for the mobile terminal (such as a mobile phone, a tablet computer, etc.) through a specific interface (such as a USB interface). At the same time, the monitoring camera is used to capture the relevant data during the charging process (such as charging current, voltage, etc.), and these data are then sent to the monitoring display screen through an optical fiber.

[0084] In a possible implementation, an FM signal generator outputs a 1Khz audio with a frequency of 98.1Mhz and outputs it to the domain controller through a coaxial cable, then outputs it to the in-vehicle speaker through a power amplifier chip, and then an audio optical fiber converter is connected in parallel on the speaker to transmit the signal to the audio analyzer outside the dark room through an optical fiber to display the changes in the volume size (voltage level) and the quality of the audio (signal-to-noise ratio) in real time. The in-vehicle camera records the real-time video and sends it to the domain controller, and then the domain controller's deserialization chip sends the video to the in-vehicle display screen. The monitoring camera in the dark room converts the image on the in-vehicle display screen to the monitor outside the dark room through an optical fiber for real-time monitoring.

[0085] It should be noted that the target scenarios that can be achieved by the above steps S301 to S305 include audio test monitoring scenarios, video recording function test monitoring scenarios, and charging function test monitoring scenarios.

[0086] The monitoring method for the domain controller function test provided in this embodiment can effectively remotely monitor the audio function of the domain controller by combining the use of the speaker and the audio analyzer.

[0087] Meanwhile, through the in-vehicle camera, monitoring display screen, monitoring camera, and in-vehicle display screen, the image transmission function of the domain controller can be accurately monitored.

[0088] In addition, through the combined use of the mobile terminal, monitoring camera, and monitoring display screen, the charging function of the domain controller can be effectively monitored.

[0089] Please refer to Figure 4 , Figure 4 which is a modular schematic diagram of the monitoring system for the domain controller function test provided by the embodiments of the present invention.

[0090] In a possible implementation, please refer to Figure 4 , the control device includes: a mobile terminal, a radar, an in-vehicle display screen, a speaker, a monitoring camera, a monitoring display screen, a host computer, a CAN signal parsing box, and an audio analyzer. The mobile terminal, radar, in-vehicle display screen, speaker, and monitoring camera are arranged in a shielding space. The radar, in-vehicle display screen, speaker, and CAN signal parsing box are respectively connected to the domain controller, and the host computer and the CAN signal parsing box are communicatively connected. The monitoring camera is communicatively connected to the monitoring display screen through a fifth optical fiber (i.e., Figure 4 the optical fiber conversion between the monitoring camera and the monitoring display screen in Figure 4 ), and the speaker is communicatively connected to the audio analyzer through a sixth optical fiber (i.e.,

[0091] Step S401, controlling the domain controller to obtain the second audio signal sent by the mobile terminal, and amplifying the second audio signal and sending it to the speaker, so that the speaker sends the amplified second audio signal to the audio analyzer; wherein, the audio analyzer performs analysis and testing based on the amplified second audio signal.

[0092] Control the domain controller to receive the second audio signal from the mobile terminal (such as a mobile phone, tablet, etc.), then amplify this signal, and send it to the speaker. The speaker then sends the amplified audio signal to the audio analyzer for analysis and testing.

[0093] As an example, a mobile phone plays an audio, and this audio is received by the domain controller as the second audio signal. After the domain controller amplifies this audio, it is played through the speaker, and at the same time, the speaker sends the amplified audio signal to the audio analyzer for analysis to check the audio quality.

[0094] Step S402, controlling the domain controller to obtain the third image data sent by the radar through the CAN message, and sending the third image data to the in-vehicle display screen.

[0095] The domain controller receives the third image data sent by the radar via CAN (Controller Area Network) messages and sends this data to the in-vehicle display for display.

[0096] As an example, when the radar detects an obstacle ahead, it sends the image data of the obstacle to the domain controller via CAN messages. After receiving this data, the domain controller sends it to the in-vehicle display and presents it as an image to the driver.

[0097] Step S403: Control the monitoring camera to collect the third image data displayed on the in-vehicle display and send the third image data to the monitoring display via the fifth optical fiber to monitor the third image data displayed on the in-vehicle display.

[0098] Control the monitoring camera to collect the third image data displayed on the in-vehicle display and send this data to the monitoring display via the fifth optical fiber so that the monitoring personnel can remotely monitor the content of the in-vehicle display.

[0099] As an example, the monitoring camera is aimed at the in-vehicle display to capture the radar image data displayed on the screen. Then, this data is transmitted to the display screen in the monitoring center via the fifth optical fiber for the monitoring personnel to view.

[0100] Step S404: Control the domain controller to convert the CAN message into an optical signal and send the optical signal to the CAN signal parsing box so that the CAN signal parsing box can parse the optical signal to determine the target CAN message.

[0101] Control the domain controller to convert the received CAN message into an optical signal and send these optical signals to the CAN signal parsing box. The CAN signal parsing box parses these optical signals to determine the target CAN message. Among them, the CAN signal parsing box is communicatively connected to the domain controller via the seventh optical fiber (i.e., Figure 4 the optical fiber conversion between the CAN signal parsing box and the domain controller in ).

[0102] As an example, the domain controller receives multiple CAN messages, and some of these messages contain radar data. The domain controller converts these messages into optical signals and sends them to the CAN signal parsing box. The parsing box parses these optical signals and extracts the target CAN message containing radar data.

[0103] Step S405: Control the host computer to receive the target CAN message and display the status of the target CAN message to determine whether the radar is working properly.

[0104] The control host computer (such as a computer, a workstation, etc.) receives the target CAN messages and displays the status of these messages on the screen of the host computer so that the staff can determine whether the radar is in a normal working state.

[0105] As an example, the host computer receives the target CAN messages sent by the CAN signal parsing box and displays the status information of these messages (such as data content, sending time, etc.) on the screen. By observing this information, the staff can judge whether the radar is working properly, such as whether the radar data is accurate and whether there is an abnormal alarm.

[0106] In specific implementation, it is interconnected with the mobile phone via Bluetooth. The audio source is input through the mobile phone Bluetooth to the domain controller and then output through the vehicle-mounted speaker. Then, an audio fiber optic converter is connected in parallel on the speaker, and the signal is transmitted to the audio analyzer outside the dark room through the optical fiber to display the change of the volume size (the level of voltage) and the quality of the audio (signal-to-noise ratio) in real time. The specific CAN messages of the radar are fed back to the vehicle head unit, then converted to the CAN parsing box through the optical fiber, and the CAN parsing box then displays the status of the specific messages through the host computer of the PC to show whether the radar status is normal.

[0107] It should be noted that the target scenarios that can be achieved by the above steps S401 to S405 include: the Bluetooth function test and monitoring scenario and the radar function test and monitoring scenario.

[0108] The monitoring method for the domain controller function test provided in this embodiment can effectively remotely monitor the audio function of the domain controller by the combined use of the mobile terminal, the speaker and the audio analyzer.

[0109] At the same time, by the combined use of the radar, the vehicle-mounted display screen, the monitoring camera and the monitoring display screen, the image transmission function of the domain controller can be effectively remotely monitored.

[0110] In addition, by the combined use of the CAN signal parsing box and the host computer, it can effectively monitor whether the radar is in a normal working state.
