Description

Technical Field

[0001] The present application relates to the field of vehicle inspection, and in particular to a vehicle electrical inspection method and device. Background Art

[0002] Vehicle electrical inspection during the manufacturing process refers to the inspection of the electronic and electrical systems after the vehicle is assembled on the production line, with the aim of ensuring normal functionality and safety.

[0003] The general electrical inspection process is that when the vehicle to be inspected arrives at the electrical inspection station, the electrical inspector uses a handheld scanning device to scan the barcode on the card attached to the vehicle to obtain the VIN (Vehicle Identification Number) code of the vehicle. The scanning device sends the VIN code to the electrical inspection system integrated in the vehicle computer. The electrical inspection system sends the VIN code to the server. The server retrieves the vehicle configuration information based on the VIN code, which includes the hardware configuration, software version, and basic functions of all ECUs (Electronic Control Units) on the vehicle. After the server feeds back the configuration information to the electrical inspection system, the electrical inspection system generates a corresponding electrical inspection plan based on the configuration information and performs the electrical inspection.

[0004] The general electrical inspection content includes determining whether the theoretical hardware configuration and software version of the ECU in the configuration information are the same as the actual hardware configuration and software version of the ECU in the vehicle to be inspected. If so, the basic functions of each ECU will be tested to determine whether it can achieve the predetermined basic functions. If not, an alarm will be issued and the electrical inspection personnel will need to replace or modify the abnormal ECU to ensure that the actual ECU configuration is consistent with the theoretical ECU configuration.

[0005] The problem with the existing technology is that the vehicle-attached card is modified by different operators during the early stage of the vehicle's transportation on the production line and then placed on the vehicle. It is easy to lose, and the VIN code on the card is also prone to errors. Manual scanning is time-consuming and has low accuracy. In addition, currently the scanning to obtain the electrical inspection plan is not started until the vehicle arrives at the electrical inspection station. If you want to complete some electrical inspection projects that require advance preparation, you need to wait at the electrical inspection station for these preparations to be completed, which is inefficient.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 This is a flow chart of an embodiment of the vehicle electrical inspection method of the present application. DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0024] In a first aspect, an embodiment of the present application provides a vehicle electrical inspection method.

[0025] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the vehicle electrical inspection method of this application. Figure 1 As shown, the above vehicle electrical inspection method includes: Step S1: pre-acquire the vehicle identification code of each vehicle to be inspected and the ID information of at least one specific electronic control unit on each vehicle to be inspected.

[0026] Step S2: Generate a configuration association table based on the vehicle identification code, ID information, and standard configuration information of each vehicle to be inspected, and store it on the server. The standard configuration information includes the software and hardware configuration and basic functions of all electronic control units on the corresponding vehicle.

[0027] Step S3: After the electric inspection system detects that the vehicle has reached the designated location, it collects the ID information of at least one specific electronic control unit and sends it to the server to obtain the corresponding vehicle identification code and standard configuration information from the server.

[0028] Step S4: The electrical inspection system generates an electrical inspection plan according to the vehicle identification code and the standard configuration information, and performs an electrical inspection on the vehicle to be inspected according to the electrical inspection plan.

[0029] In this embodiment, by pre-storing the association between the vehicle identification code of each vehicle to be inspected and the specific electronic control unit on the server, after the vehicle to be inspected arrives at the designated location, the electronic inspection system integrated on the vehicle to be inspected is used to automatically collect the ID information of the specific electronic control unit, and send the ID information to the server to obtain the accurate vehicle identification code and corresponding standard configuration information of the vehicle to be inspected, thereby avoiding the inefficiency and errors of manual code scanning. After obtaining the standard configuration information, the electronic inspection system automatically generates a corresponding electronic inspection plan for electronic inspection, thereby realizing the automation of electronic inspection operations and improving electronic inspection efficiency.

[0030] In one specific embodiment, each component or function of the distributed architecture corresponds to an independent ECU. For example, engine control is handled by the ECM (Engine Control Module). Vehicle body functions, such as doors, windows, and seats, may be controlled by multiple independent ECUs (such as door controllers and window controllers). ADAS (Advanced Driving Assistance System) systems, such as parking controllers and surround view controllers, have independent ECUs for each assisted driving function. Each ECU has its own independent and unique ID information, which includes information such as the ECU's hardware configuration and software version. Each vehicle to be inspected has as many as dozens of ECUs and corresponding ID information. In the present invention, only the specific ECU on each vehicle to be inspected is bound to the VIN code. The VIN code of the vehicle is queried by querying the ID information of the specific ECU. When selecting a specific ECU among all ECUs, an ECU with a unique configuration is preferred. For example, the vehicle control ECU of vehicle A has different ID information from the vehicle control ECUs of other vehicles. The vehicle control ECU is used as the specific ECU of vehicle A. There can be multiple specific ECUs on the same vehicle to be inspected, so that when any one or more specific ECUs fail, the electrical inspection system can still collect the ID information of the remaining specific ECUs that have not failed, thereby obtaining the vehicle VIN code.

[0031] Furthermore, in one embodiment, the above-mentioned collecting ID information of at least one specific electronic control power supply and sending it to the server specifically includes the following steps: The electrical inspection system sends a collection instruction to each specific electronic control unit, and the specific electronic control unit feeds back ID information to the electrical inspection system according to the collection instruction.

[0032] The electronic inspection system determines whether it has received the ID information fed back by all specific electronic control units. If so, it sends the received ID information to the server. If not, it records the ID information that has not been received as an alarm and sends the received ID information to the server.

[0033] In this embodiment, when there are multiple specific ECUs on the vehicle to be inspected, if there is a specific ECU that does not respond to the collection instruction, the electrical inspection system will mark the specific ECU. According to actual needs, the specific ECU can be directly alarmed so that the electrical inspection personnel can directly maintain it, or the relevant information of the specific ECU can be sent to the server so that the subsequent fault identification model can perform fault analysis on it.

[0034] It should be emphasized that after the vehicle to be inspected obtains the initial electrical inspection plan, when passing through different electrical inspection stations, it can directly skip the station where the electrical inspection is performed on the specific ECU that does not respond to the collection instruction according to the electrical inspection plan, thereby improving the completion speed of the remaining electrical inspection items.

[0035] Furthermore, in one embodiment, the above-mentioned obtaining the corresponding vehicle identification code and standard configuration information from the server specifically includes the following steps: The server queries the above configuration association table based on all the ID information received for the same vehicle to be inspected, and determines whether all the ID information is associated with the same vehicle identification code. If so, the vehicle identification code is fed back to the electronic inspection system. If not, the vehicle identification code with the highest matching degree with the ID information is fed back to the electronic inspection system.

[0036] In this embodiment, the ID information fed back to the electrical inspection system by each specific ECU may be inconsistent with the theoretical ID information of the vehicle in the standard configuration table. At this time, the VIN code associated with the ID information of most specific ECUs is fed back to the vehicle to be inspected. The server and / or the electrical inspection system can mark the specific ECU. According to actual needs, an alarm can be directly issued to the specific ECU so that the electrical inspection personnel can directly perform maintenance on it. The relevant information of the specific ECU can also be sent to the server so that the subsequent fault identification model can perform fault analysis on it.

[0037] It should be emphasized that after the vehicle to be inspected obtains the initial electrical inspection plan, when passing through different electrical inspection stations, it can directly skip the station where the electrical inspection is performed on the specific ECU that does not respond to the collection instruction according to the electrical inspection plan, thereby improving the completion speed of the remaining electrical inspection items.

[0038] Furthermore, in one embodiment, the vehicle electrical inspection method further includes: The correlation between the functional failure of the electronic control unit and the cause of the failure is obtained in advance, and a fault identification model is trained and stored in the server.

[0039] After the electrical inspection system performs electrical inspection according to the electrical inspection plan, it sends the electrical inspection results to the server. The server uses the fault identification model to perform fault analysis on the electrical inspection results, obtains the cause of the fault, and feeds back the fault cause to the electrical inspection system.

[0040] The electrical inspection system updates the subsequent electrical inspection plan based on the cause of the fault.

[0041] Furthermore, in one embodiment, the vehicle electrical inspection method further includes: When the electrical inspection system fails to collect the ID information of a specific electronic control unit, or when the ID information collected by the electrical inspection system is incorrect, the relevant information is sent to the server, and the fault identification model is used to perform fault analysis to obtain the cause of the fault, and the cause of the fault is fed back to the electrical inspection system.

[0042] The electrical inspection system updates the subsequent electrical inspection plan based on the cause of the fault.

[0043] In this embodiment, a fault analysis function is added to the electrical inspection operation, and the functions of the electrical inspection operation are expanded, so that electrical inspection, fault detection, and fault handling are closely integrated in the electrical inspection process, thereby improving the overall vehicle inspection and maintenance efficiency.

[0044] In a second aspect, an embodiment of the present application also provides a vehicle electrical inspection device.

[0045] In one embodiment, the vehicle electrical inspection device includes: The preprocessing module is used to pre-acquire the vehicle identification code (VIC) of each vehicle to be inspected, as well as the ID information of at least one specific electronic control unit (ECU) on each vehicle. Based on the VIC, ID information, and standard configuration information for each vehicle to be inspected, a configuration association table is generated and stored on the server. This standard configuration information includes the hardware and software configurations and basic functions of all ECUs on the corresponding vehicle.

[0046] The above-mentioned server is used to store the above-mentioned configuration association table.

[0047] The electronic inspection system is used to detect that a vehicle has arrived at the electronic inspection station, collect the ID information of at least one specific electronic control unit, and send it to the server, which then retrieves the corresponding vehicle identification code and standard configuration information. The system is also used to generate an electronic inspection plan based on the vehicle identification code and standard configuration information, and perform an electronic inspection on the vehicle according to the electronic inspection plan.

[0048] In this embodiment, by pre-storing the association between the vehicle identification code of each vehicle to be inspected and the specific electronic control unit on the server, after the vehicle to be inspected arrives at the designated location, the electronic inspection system integrated on the vehicle to be inspected is used to automatically collect the ID information of the specific electronic control unit, and send the ID information to the server to obtain the accurate vehicle identification code and corresponding standard configuration information of the vehicle to be inspected, thereby avoiding the inefficiency and errors of manual code scanning. After obtaining the standard configuration information, the electronic inspection system automatically generates a corresponding electronic inspection plan for electronic inspection, thereby realizing the automation of electronic inspection operations and improving electronic inspection efficiency.

[0049] Furthermore, in one embodiment, the above-mentioned electrical inspection system collects ID information of at least one specific electronic control power supply and sends it to the server, and sends a collection instruction to each specific electronic control unit. The specific electronic control unit feeds back the ID information to the electrical inspection system according to the collection instruction.

[0050] The electronic inspection system determines whether it has received the ID information fed back by all specific electronic control units. If so, it sends the received ID information to the server. If not, it records the ID information that has not been received as an alarm and sends the received ID information to the server.

[0051] In this embodiment, when there are multiple specific ECUs on the vehicle to be inspected, if there is a specific ECU that does not respond to the collection instruction, the electrical inspection system will mark the specific ECU. According to actual needs, the specific ECU can be directly alarmed so that the electrical inspection personnel can directly maintain it, or the relevant information of the specific ECU can be sent to the server so that the subsequent fault identification model can perform fault analysis on it.

[0052] It should be emphasized that after the vehicle to be inspected obtains the initial electrical inspection plan, when passing through different electrical inspection stations, it can directly skip the station where the electrical inspection is performed on the specific ECU that does not respond to the collection instruction according to the electrical inspection plan, thereby improving the completion speed of the remaining electrical inspection items.

[0053] Furthermore, in one embodiment, when the above-mentioned electrical inspection system obtains the corresponding vehicle identification code and standard configuration information from the server, the server queries the above-mentioned configuration association table based on all the ID information received of the same vehicle to be inspected, and determines whether all the ID information is associated with the same vehicle identification code. If so, the vehicle identification code is fed back to the electrical inspection system; if not, the vehicle identification code with the highest matching degree with the ID information is fed back to the electrical inspection system.

[0054] In this embodiment, the ID information fed back to the electrical inspection system by each specific ECU may be inconsistent with the theoretical ID information of the vehicle in the standard configuration table. At this time, the VIN code associated with the ID information of most specific ECUs is fed back to the vehicle to be inspected. The server and / or the electrical inspection system can mark the specific ECU. According to actual needs, an alarm can be directly issued to the specific ECU so that the electrical inspection personnel can directly perform maintenance on it. The relevant information of the specific ECU can also be sent to the server so that the subsequent fault identification model can perform fault analysis on it.

[0055] It should be emphasized that after the vehicle to be inspected obtains the initial electrical inspection plan, when passing through different electrical inspection stations, it can directly skip the station where the electrical inspection is performed on the specific ECU that does not respond to the collection instruction according to the electrical inspection plan, thereby improving the completion speed of the remaining electrical inspection items.

[0056] Furthermore, in one embodiment, the pre-processing module is further configured to obtain in advance the correlation between the functional failure of the electronic control unit and the cause of the failure, and train a fault identification model and store it in the server. The server is further configured to store the fault identification model.

[0057] The above-mentioned electrical inspection system is also used to send the electrical inspection results to the server after performing electrical inspection according to the electrical inspection plan. The server uses the fault identification model to perform fault analysis on the electrical inspection results, obtain the cause of the fault, and feed back the fault cause to the electrical inspection system.

[0058] The above-mentioned electrical inspection system is also used to update subsequent electrical inspection plans according to the cause of the fault.

[0059] Furthermore, in one embodiment, the above-mentioned electrical inspection system is also used to send relevant information to the server when the ID information of a specific electronic control unit is not collected, and when the ID information collected by the electrical inspection system is incorrect, perform fault analysis using a fault identification model, obtain the cause of the fault, and feed back the cause of the fault to the electrical inspection system.

[0060] The above-mentioned electrical inspection system is also used to update subsequent electrical inspection plans according to the cause of the fault.
