Therefore, when suppliers design the communication architecture of in-vehicle networks, they need to simulate and analyze the communication delays of sensors in the network. However, in the prior art, there is no topology map that can display test network nodes. In addition, as the number of access node devices such as ECUs and sensors increases, it is impossible to display all of them on a small in-vehicle screen, making it impossible for users to clearly understand the network access node devices and their corresponding states at a glance.

As mentioned herein, a hybrid vehicle is a vehicle having two or more power sources, such as a vehicle with both gasoline power and electric power.

[0039] The present invention provides a method for displaying a network topology map of an intelligent vehicle, which is used for an in-vehicle Ethernet test device to display the accessed network devices. See Figures 1 to 7 , specifically including:

[0040] Obtain the network nodes of the in-vehicle network and monitor the network nodes;

[0041] If there are devices accessed by the network nodes, mark the nodes;

[0042] According to the marked nodes, obtain the corresponding picture library from the image database;

[0043] Generate a global network topology map and a local network topology map according to the network communication connection relationship formed by the library and the network nodes with devices connected, where the scale of the global network topology map is smaller than that of the local network topology map. As Figure 1 shown, the display screen is divided into left and right parts, with the local network topology map shown on the right part and the global network topology map shown in the upper left corner.

[0044] Specifically, there are multiple ECUs in an intelligent vehicle. In order to perform health monitoring on numerous ECUs, access the in-vehicle network through an in-vehicle Ethernet test device, obtain the node devices connected in the network, and display them. However, due to the limited display screen size of the access device of the in-vehicle Ethernet test device, if the number of ECUs and the number of gateways increase, the screen cannot be fully displayed. This makes it impossible for test analysts to comprehensively grasp the current state of the in-vehicle network. By implementing the above method, the global network topology map and the local network topology map are used for separate display.

[0045] The global network topology map displays the overall picture of the entire in-vehicle network in a reduced manner, and the local network topology map displays the overall picture of the local clear device connections in a preset proportional size. The specific display area can be displayed according to the area indicated by the global network topology map.

[0046] The global network topology map fully displays the network connections composed of marked node devices in a reduced scale;

[0047] The local network topology map locally displays the devices composed of marked nodes by stretching, adapting the size, or within the preset proportional range of the current window.

[0048] Specifically, the global network topology map is displayed in a reduced scale of 5 to 10 times;

[0049] The local network map specifically determines the magnification according to the current screen size to ensure that it is clear for human eyes to view.

[0050] Specifically, according to the number of access devices, the local network topology map displays the entire network device connection topology map or the topology map of part of the network device connections.

[0051] If the number of currently connected devices is small, the local network topology map can fully display everything;

[0052] Or if the number of currently connected devices is large, the local network displays part of the network nodes.

[0053] When the local network topology map displays part of the network node devices, if the user's currently tested node does not exist in the local network topology map, the user views the corresponding node in the global network topology map and selects the display area;

[0054] After selecting the display area, update the current local network topology map with the selected display area.

[0055] The connected devices include one or more of switches, networks, ECUs, and sensors.

[0056] Specifically, there are many devices such as in-vehicle ECUs, sensors, TSN gateways, and switches. The sensors include in-vehicle cameras, lidar, millimeter-wave radars, and ultrasonic radars;

[0057] Analyze and simulate the connected network node devices through the in-vehicle Ethernet test device to analyze whether the current in-vehicle sensors, ECUs, and gateways can communicate and work properly. If there are problems, alarm in time for maintenance to improve reliability.

[0058] The global network topology map displays the connection topology map of the entire in-vehicle network devices in a scaled manner;

[0059] Specifically, this embodiment also provides a method for constructing a network topology map, which is as follows:

[0060] The construction of the network topology map includes:

[0061] Step S1: Set the topology map editing area and the topology element list;

[0062] Step S2: Select the element to be added from the element list, drag it to the topology map editing area with the mouse, and then release the mouse to complete the addition of the element;

[0063] Step S3: If the element needs to be renamed, double-click the element to rename it.

[0064] See Figure 2 , Figure 2 In, the global network topology map is displayed in the upper right corner. Set the wireframe to select the editing area.

[0065] The topology map editing area is displayed on the right, and the topology map is edited through the topology map editing area. At the top, there are pointer tools, connection lines, routing, and text.

[0066] The user can edit the network topology map in the topology map editing area. Elements can be added to the network topology map from the element list, or a selected added element or line can be deleted or edited. As Figure 3 shown.

[0067] Editing of the network topology map - Adding elements:

[0068] Select the element to be added from the element list, drag it to the editing area with the mouse, and release to complete the addition of the element;

[0069] Double-clicking on a component already added to the editing area allows you to rename it. For example: switch1;

[0070] Editing of the network topology diagram - Connecting lines:

[0071] Click on "Connecting Lines" above the editing area, and the mouse mode in the editing area will be the line connection mode.

[0072] Press and hold the mouse on one of the two components that need to be connected, drag it to the other component, and then release the mouse to complete the network connection function.

[0073] Specifically, the construction of the global network topology view includes:

[0074] Obtain the scene display diagram, the global network topology view, and the editing view;

[0075] Set the window sizes of the scene display diagram, the global network topology view, and the editing view respectively;

[0076] Assume the scene size is 2000x2000, the window of the global network topology view is 200x200, and the editing view is 800x800;

[0077] The view of the global network topology map is to scale the scene by 5 to 10 times;

[0078] The editing area is a local area of the scene and can be displayed as a local network topology map;

[0079] Assume the coordinates of the editing view are (0,0,800,800) and convert them to scene coordinates. Assume the coordinates after conversion are (500,700,1000,1000), and then convert them to the coordinates of the wireframe of the global network topology map (50,70,100,100);

[0080] Specifically, refer to Figure 5 and Figure 6 , Figure 5 Show the layout of the three maps, Figure 6 Show the specific implementation steps.

[0081] Specifically, for the editing of the network topology diagram - changing the coordinates of the editing view in the scene through the wireframe of the global network topology map, as Figure 7 shown;

[0082] Specifically, it includes the following steps:

[0083] Drag the global network topology map;

[0084] Obtain the coordinates of the upper left corner of the wireframe in the global network topology map;

[0085] Convert wireframe coordinates to scene coordinates;

[0086] Sets the scene coordinates of the editing view.

[0087] Specifically, suppose you drag a wireframe in the global network topology map with the mouse, and the upper left coordinate of the wireframe changes from (50,70) to (80,55). Convert (80,55) to the scene coordinate (800,550), and then set the scene coordinate of the editing view to (800,500).

[0088] Specifically, click the "Connection Line" above the topology map editing area to change the mouse mode of the editing area to the connection mode;

[0089] Press the mouse on one of the two components that need to be connected, drag it to the other component, and release the mouse to complete the network connection function.

[0090] The network nodes in the network topology map display different graphics according to the type of connected devices.

[0091] Different communication buses in the network topology map Different communication buses are displayed with different line types.

[0092] When network node devices are added or deleted, the global network topology map will add or delete corresponding node devices accordingly.

[0093] The above are only preferred embodiments of the present invention, and the present invention is not limited to the above embodiments. It is clear to those skilled in the art that the form in the embodiment is not limited thereto, and the adjustable manner is not limited thereto. It is understood that other improvements and changes directly derived or associated with those skilled in the art without departing from the basic concept of the present invention should be considered to be included in the protection scope of the present invention.
