[0020] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 , Figure 2 As shown, this embodiment provides a wiring harness inspection and control method in the prototype vehicle trial production stage:

[0022] S1. SYS sorting: Get the SYS wiring harness schematic diagram collection file, then filter out the SYS wiring harness schematic diagram suitable for the sample vehicle according to the sample vehicle model, and sort it into a single vehicle SYS wiring harness schematic diagram collection file.

[0023] S2. Wire table processing: Obtain the technical documents of the wire harness production process, which include the WIRE table, i.e., the universal wire harness loop table; extract the configuration information according to the vehicle definition of the prototype vehicle, filter out the wire harness model used by the prototype vehicle from the WIRE table through the configuration information, and collect and organize them to form a single-vehicle wire harness loop table suitable for the prototype vehicle.

[0024] S3, schematic diagram verification: verify the information on the bicycle wiring harness loop table through the bicycle SYS wiring harness schematic diagram collection file;

[0025] S4, 3D inspection of wiring harness: Use VTO data to perform 3D inspection on the wiring harness, check the matching between the wiring harness plug and the electrical components, and check the loading list and the direction of the wiring harness plug;

[0026] S5. CAN line inspection: Evaluate the wiring harness layout of the sample vehicle according to the CANBUS file, including whether the design of the terminal resistor meets the specifications; use the CAN, LIN and Ethernet layout in the vehicle controller CAN topology diagram to check the SYS wiring harness schematic diagram and wiring harness loop table.

[0027] In a more specific embodiment, the SYS sorting step specifically includes: downloading the SYS wiring harness schematic diagram collection file related to the prototype project from the system platform of the vehicle manufacturer. Checking whether each schematic diagram in the SYS wiring harness schematic diagram collection file can be used in this prototype project according to the list of applicable models on the schematic diagram, for example, "x" can be marked to represent available, and blank can represent unavailable. Filter out the SYS wiring harness schematic diagrams suitable for the prototype vehicle, sort them into a single vehicle SYS wiring harness schematic diagram collection file, and create a schematic diagram directory for easy later search.

[0028] In a more specific embodiment, the wire list processing steps specifically include: first, obtain the wire harness technical documents from the wire harness manufacturer. The manufacturer provides 5 technical folders (cockpit, engine compartment, front and rear bumpers, doors, and auxiliary instrument ceiling). Each compressed package includes a BOM table (parts list: standardizes the parts used in the wire harness), a WIRE (wire harness loop table), and a wire harness 2D drawing (standardizes the wire harness size and spatial position, used for the production of the wire harness). The WIRE table standardizes the direction of each wire harness of each plug. It is a universal set. It is necessary to find the single vehicle wire harness loop table based on the vehicle PR information, select the wire harness and code to be used based on the PR number (configuration information) defined by the vehicle, and at the same time filter out the wire harness loop used in this wire harness collection in the wire table. In this way, the WIRE tables of the cockpit, engine compartment, front and rear bumpers, doors, and auxiliary instrument ceiling can be processed to generate a single vehicle wire harness loop table for subsequent use and inspection.

[0029] In a more specific embodiment, the schematic diagram verification step specifically includes: selecting electrical components on the schematic diagram. Since the schematic diagram is a large collection, we need to find the electrical components we need. Select the electrical components needed for this sample vehicle according to the vehicle model and vehicle configuration information-PR number. According to the information on the electrical component PIN, find the corresponding plug number on the corresponding WIRE. For example: The P gear actuator finds the plug number PAA by searching S.SHLCK in the corresponding column Verbindung in the WIRE table of the cockpit. Note: Try to select a wiring harness description that has features on the schematic diagram to avoid solder joints / or multiple uses of one point. Use the schematic PIN information to check the information on the wire table, and check the component drawing number, wiring harness description, Pin information, and schematic terminal. The wire table terminal may involve multiple WIREs.

[0030] In a more specific embodiment, the wiring harness 3D inspection step specifically includes: For the wiring harness 3D inspection, the wiring harness 3D inspection work is carried out using the VTO data provided by the technical team, and the 3D inspection replaces the 2D drawing inspection. The VTO data can intuitively display the matching relationship between the plug and the electrical components. Check the matching between the wiring harness plug and the electrical components (check the loading list and the wiring harness plug). Check the direction of the wiring harness plug: For example, wireless charging is plugged into the IR wiring harness through the auxiliary instrument.

[0031] In a more specific embodiment, the CAN line inspection step specifically includes: obtaining a CANBUS file for the project from the supplier, and evaluating the wiring harness layout according to the CAN line design of the CANBUS. Evaluating whether the design of the terminal resistor meets the specification. Obtaining a controller topology file for the project from the product department, and using the CAN, LIN and ETH (Ethernet) layout in the topology diagram to check the schematic diagram and wiring harness loop table.

[0032] In a more specific embodiment, the wiring harness inspection and control method further includes step S6, principle inspection: the controller PIN information obtained from the wiring harness inspection of the previous project is checked against the wiring harness principle of the current prototype vehicle project. For example, the working principle of the gearbox of the current prototype vehicle project is compared with that of the previous project, the wiring harness description and the number of PINs are checked, and the different wiring harnesses are found and confirmed.

[0033] In a more specific embodiment, the wiring harness inspection and control method further includes step S7, problem supervision: recording problem information and feeding back to relevant personnel. The relevant personnel information can be found through the parts list.

[0034] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
