Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing, and more specifically to a whole vehicle electrical inspection quality control system. Background Technology

[0002] During the automobile manufacturing process, the functions of different controllers in the vehicle need to be configured and software data needs to be flashed according to the vehicle model. To meet the demand for personalized vehicle customization, vehicle configurations and software data are updated frequently. Any untimely or incorrect updates to the electrical testing system and ECU flashing software database will affect the vehicle's electrical testing process and cause quality problems. Summary of the Invention

[0003] The purpose of this invention is to provide a vehicle electrical inspection quality control system to solve electrical inspection quality problems caused by untimely or incorrect updates of the electrical inspection configuration module and ECU flashing software data module during vehicle production, due to ECU configuration and software data updates. Specifically, it can provide early warnings and track and manage potential electrical inspection failures.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A vehicle electrical inspection quality control system, comprising:

[0006] The vehicle electrical inspection configuration module is used to store and maintain vehicle electrical inspection configuration information, which is called by the electrical inspection equipment when performing vehicle electrical inspection configuration.

[0007] The ECU flashing software data module is used to store and maintain vehicle ECU flashing software data, which is called by the electrical testing equipment when performing vehicle ECU software flashing.

[0008] The vehicle inspection quality control module stores the maintenance status of vehicle inspection configuration information and vehicle ECU flashing software data. It includes an inspection configuration information query element, an ECU flashing information query element, and an inspection quality problem generation element. After obtaining the information of the vehicle to be inspected, the inspection quality control module queries the inspection configuration module through the inspection configuration information query element to see if the inspection configuration information of the vehicle to be inspected has been updated, and queries the ECU flashing information query element to the ECU flashing software data module to see if the ECU flashing software data of the vehicle to be inspected has been updated. The inspection quality problem generation element generates an inspection quality problem record table based on the query results.

[0009] Furthermore, it also includes an information sending module, which generates a prompt message after generating an electrical inspection quality problem and sends the prompt message to the receiving terminal of the corresponding personnel.

[0010] Furthermore, it also includes a vehicle information acquisition module, which is used to acquire vehicle information and send the vehicle information to the electrical inspection quality control module.

[0011] Furthermore, the electrical inspection quality control module periodically checks the rectification status of unclosed issues in the electrical inspection quality problem record table generated by the electrical inspection quality problem generation element, and closes the rectified issues.

[0012] Furthermore, if the electronic inspection configuration module fails to update the electronic inspection configuration information of the vehicle to be inspected, or the ECU flashing software data module fails to update the ECU flashing software data of the vehicle to be inspected, then a first mark is made in the generated electronic inspection quality problem record table, and task information is generated.

[0013] If the query shows that the electrical inspection configuration module has updated the electrical inspection configuration information of the vehicle to be inspected and the ECU flashing software data module has updated the ECU flashing software data of the vehicle to be inspected, then a second mark will be made in the generated electrical inspection quality problem record table, and the vehicle to be inspected can go to the electrical inspection station for electrical inspection.

[0014] Furthermore, the workflow for querying electrical inspection configuration information components specifically includes the following steps:

[0015] S11, the electronic inspection configuration information query element compares the obtained vehicle information to be inspected with the vehicle model information stored in the electronic inspection configuration module to determine whether the electronic inspection configuration information for the corresponding vehicle model has been maintained. If yes, the process ends; otherwise, S12 is executed.

[0016] S12, compare the vehicle information to be inspected with the vehicle electrical inspection configuration information maintenance status stored in the electrical inspection quality control module. If the stored vehicle electrical inspection configuration information maintenance status has recorded the corresponding vehicle model, then make a first mark in the electrical inspection quality problem record table generated by the electrical inspection quality problem generation element and generate task information; if the stored vehicle electrical inspection configuration information maintenance status has not recorded the corresponding vehicle model, then update the vehicle electrical inspection configuration information maintenance status in the electrical inspection quality control module, and make a first mark in the electrical inspection quality problem record table generated by the electrical inspection quality problem generation element and generate task information.

[0017] Furthermore, the vehicle electrical inspection configuration information maintenance status is updated in real time by periodically comparing the vehicle electrical inspection configuration information maintenance status stored in the electrical inspection quality control module with the vehicle electrical inspection configuration information stored in the electrical inspection configuration module.

[0018] Furthermore, the workflow for querying ECU flashing information includes the following steps:

[0019] S11, the ECU flashing information query element compares the acquired vehicle information to be inspected with the vehicle model information in the vehicle ECU flashing software data stored in the ECU flashing software data module to determine whether the ECU flashing software data corresponding to the vehicle model to be inspected has been maintained. If yes, the process ends; otherwise, S12 is executed.

[0020] S12, compare the vehicle information to be inspected with the vehicle ECU flashing software data maintenance status stored in the electronic inspection quality control module. If the stored vehicle ECU flashing software data maintenance status has recorded the corresponding vehicle model, then make a first mark in the electronic inspection quality problem record table generated by the electronic inspection quality problem generation element and generate task information; if the stored vehicle ECU flashing software data maintenance status has not recorded the corresponding vehicle model, then update the vehicle ECU flashing software data maintenance status in the electronic inspection quality control module, and make a first mark in the electronic inspection quality problem record table generated by the electronic inspection quality problem generation element and generate task information.

[0021] Furthermore, the vehicle ECU flashing software data maintenance status is updated in real time by periodically comparing the vehicle ECU flashing software data maintenance status stored in the electronic inspection quality control module with the vehicle ECU flashing software data stored in the ECU flashing software data module.

[0022] The beneficial effects of this invention are as follows: The vehicle electrical inspection quality control system described in this invention achieves fully automated early detection, recording, information alerts, and problem closure for electrical inspection quality issues. It solves the problem of electrical inspection quality issues caused by untimely or incorrect updates of the electrical inspection configuration module and ECU flashing software data module during vehicle production, due to vehicle ECU configuration and software data updates. In other words, it can provide early warnings and track and manage potential electrical inspection failures. Attached Figure Description

[0027] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] See Figure 1 The vehicle electrical inspection quality control system shown includes: a vehicle information acquisition module, an electrical inspection configuration module, an ECU flashing software data module, an electrical inspection quality control module, and an information transmission module.

[0030] The vehicle information acquisition module is used to acquire vehicle information and send it to the electrical inspection quality control module. An RFID chip is fixed on the vehicle to be inspected, and an RFID reader / writer station is set up at the welding workshop exit. When the vehicle enters the welding workshop exit, the RFID reader / writer station identifies the RFID chip on the vehicle and obtains the vehicle information.

[0031] The electrical inspection configuration module is used to store and maintain vehicle electrical inspection configuration information, which is called by the electrical inspection equipment when performing vehicle electrical inspection configuration.

[0032] The ECU flashing software data module is used to store and maintain vehicle ECU flashing software data, which is called by the electrical testing equipment when performing vehicle ECU software flashing.

[0033] The electrical inspection quality control module is used to store the maintenance status of vehicle electrical inspection configuration information and vehicle ECU flashing software data. It includes an electrical inspection configuration information query element, an ECU flashing information query element, and an electrical inspection quality problem generation element. After obtaining the information of the vehicle to be inspected, the electrical inspection quality control module queries the electrical inspection configuration module through the electrical inspection configuration information query element to see if the electrical inspection configuration information of the vehicle to be inspected has been updated, and queries the ECU flashing information query element to the ECU flashing software data module to see if the ECU flashing software data of the vehicle to be inspected has been updated. The electrical inspection quality problem generation element generates an electrical inspection quality problem record table based on the query results. Specifically, if the electrical inspection configuration module fails to update the electrical inspection configuration information of the vehicle to be inspected, or the ECU flashing software data module fails to update the ECU flashing software data of the vehicle to be inspected, a first mark is made in the generated electrical inspection quality problem record table, and task information is generated. If the electrical inspection configuration module has updated the electrical inspection configuration information of the vehicle to be inspected, and the ECU flashing software data module has updated the ECU flashing software data of the vehicle to be inspected, a second mark is made in the generated electrical inspection quality problem record table, and the vehicle to be inspected can proceed to the electrical inspection station for electrical inspection. After generating an electrical inspection quality problem, a prompt message is generated through the information sending module and sent to the receiving terminal of the corresponding personnel.

[0034] The electrical inspection quality control module periodically checks the rectification status of unclosed issues in the electrical inspection quality problem record table generated by the electrical inspection quality problem generation element, and closes the rectified issues.

[0035] See Figure 2 The workflow for querying electrical inspection configuration information components includes the following steps:

[0036] S11, the electronic inspection configuration information query element compares the obtained vehicle information to be inspected with the vehicle model information in the vehicle electronic inspection configuration information stored in the electronic inspection configuration module to determine whether the electronic inspection configuration information of the corresponding vehicle model has been maintained. If yes, the process ends; if no, the first unmaintained details table of the vehicle to be inspected is generated, and S12 is executed.

[0037] S12, compare the vehicle information to be inspected with the vehicle electrical inspection configuration information maintenance status stored in the electrical inspection quality control module, that is, compare the first unmaintained list of vehicles to be inspected with the second unmaintained list of vehicles to be inspected stored in the control module. If the stored vehicle electrical inspection configuration information maintenance status has recorded the corresponding vehicle model, then make a first mark in the electrical inspection quality problem record table generated by the electrical inspection quality problem generation element and generate task information; if the stored vehicle electrical inspection configuration information maintenance status has not recorded the corresponding vehicle model, then update the vehicle electrical inspection configuration information maintenance status in the electrical inspection quality control module, and make a first mark in the electrical inspection quality problem record table generated by the electrical inspection quality problem generation element and generate task information.

[0038] The vehicle electrical inspection configuration information maintenance status is updated in real time by periodically comparing the maintenance status of the vehicle electrical inspection configuration information stored in the electrical inspection quality control module with the vehicle electrical inspection configuration information stored in the electrical inspection configuration module. (See also...) Figure 2 The generation of the second unmaintained details list for vehicles to be inspected is as follows: Every 5 minutes, the maintenance status of the vehicle electrical inspection configuration information stored in the electrical inspection quality control module is compared with the vehicle model information in the vehicle electrical inspection configuration information stored in the electrical inspection configuration module. It is determined whether the electrical inspection configuration information for each vehicle model has been maintained. If so, the maintenance status of the vehicle electrical inspection configuration information in the electrical inspection quality control module is updated, and the problem status in the electrical inspection quality problem record table is updated to "resolved," ending the process. If not, the second unmaintained details list for vehicles to be inspected is generated.

[0039] See Figure 3 The specific workflow for querying ECU flashing information includes the following steps:

[0040] S11, the ECU flashing information query element compares the acquired vehicle information to be inspected with the vehicle model information in the vehicle ECU flashing software data stored in the ECU flashing software data module to determine whether the ECU flashing software data corresponding to the vehicle model to be inspected has been maintained. If yes, the process ends; if no, a first unmaintained details list of the vehicle to be inspected is generated, and S12 is executed.

[0041] S12, compare the vehicle information to be inspected with the vehicle ECU flashing software data maintenance status stored in the electronic inspection quality control module, that is, compare the first unmaintained list of vehicles to be inspected with the second unmaintained list of vehicles to be inspected stored in the control module. If the stored vehicle ECU flashing software data maintenance status has recorded the corresponding vehicle model, then make a first mark in the electronic inspection quality problem record table generated by the electronic inspection quality problem generation element and generate task information; if the stored vehicle ECU flashing software data maintenance status has not recorded the corresponding vehicle model, then update the vehicle ECU flashing software data maintenance status in the electronic inspection quality control module, and make a first mark in the electronic inspection quality problem record table generated by the electronic inspection quality problem generation element and generate task information.

[0042] The vehicle ECU rewriting software data maintenance status is updated in real time by periodically comparing the vehicle ECU rewriting software data maintenance status stored in the electronic inspection quality control module with the vehicle ECU rewriting software data stored in the ECU rewriting software data module. See also Figure 3The generation of the second unmaintained details list for vehicles under inspection is as follows: Every 5 minutes, the maintenance status of the vehicle ECU flashing software data stored in the electronic inspection quality control module is compared with the vehicle model information in the vehicle ECU flashing software data stored in the ECU flashing software data data module. It is determined whether the ECU flashing software data for each vehicle model has been maintained. If so, the maintenance status of the vehicle ECU flashing software data in the electronic inspection quality control module is updated, and the problem status in the electronic inspection quality problem record table is updated to "resolved," ending the process. If not, the second unmaintained details list for vehicles under inspection is generated.

[0043] The main tasks of the vehicle electrical inspection process are as follows: At the electrical inspection station in the final assembly workshop, based on the vehicle model configuration, electrical inspection equipment is used to configure the functions and rewrite the software data of different controllers. The main function of the vehicle electrical inspection quality control system described in this invention is to periodically acquire the latest information on vehicles awaiting inspection at the welding workshop exit point. The time span from the vehicle passing this point to the electrical inspection station in the final assembly workshop is approximately one working day. The system proactively checks the relevant conditions at the downstream electrical inspection station, records and pushes information on any problems found, and automatically checks whether previously recorded problems have been rectified and closes rectified issues. This solves the electrical inspection quality problems caused by untimely or incorrect updates of the electrical inspection configuration module and ECU rewriting software data module during vehicle production, which are often due to updates to vehicle ECU configuration and software data. In other words, it can provide early warning and tracking management for problems that may cause electrical inspection failures.

[0044] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
