Detailed Description
Each ECU engineer defines in a manufacturing unit (MES) the ECU software version used by the vehicle and the ECU information in the ECU engineer's mailbox for each vehicle type and vehicle type configuration. When a vehicle needs to be produced, a loading unit (SAP) can synchronously load information to a manufacturing unit, the manufacturing unit matches the loading information with data of ECU information to generate vehicle production information, and meanwhile the vehicle production information is synchronized to an offline detection unit; when the vehicle is subjected to production offline detection, the offline detection unit is accessed to the vehicle through the OBD to acquire vehicle information, whether the vehicle information is matched with the vehicle production information or not is confirmed, if the data are matched, the offline detection unit judges that the vehicle can be normally offline, if the data are not matched, the offline detection unit intercepts the vehicle and does not allow the vehicle to be offline, meanwhile, a vehicle detection result is synchronized to the manufacturing unit, and the manufacturing unit pushes relevant engineers to process the vehicle according to failure reasons.
In order to realize the purpose, the technical scheme of the invention is as follows:
as shown in fig. 1, the invention provides a system for matching and detecting automobile ECU software, which comprises a loading unit, a manufacturing unit and an offline detection unit, wherein the functions of the units are as follows:
the loading unit generates loading information according to the number and configuration conditions of the vehicles ordered by the client and the dealer, and meanwhile pushes the loading information to the manufacturing unit.
A Manufacturing Execution System (MES) receives ECU information input by an ECU engineer, receives loading information of a loading unit, and matches the loading information with the ECU information to generate vehicle production information; meanwhile, the vehicle production information is pushed to the offline detection unit. And the system is responsible for receiving the detection result of the offline detection unit and pushing the vehicles which are detected to be inconsistent to a relevant ECU (electronic control unit) engineer mailbox for problem troubleshooting and problem reminding.
The offline detection unit is responsible for accessing and detecting vehicles through OBD, obtaining vehicle information through UDS diagnosis, comparing vehicle production information with vehicle information, feeding back detection results to the MES unit, and performing vehicle offline interception on vehicles failing offline detection.
As shown in FIG. 2, the present invention provides a method for detecting software matching of an automobile ECU, wherein a loading unit (SAP), a manufacturing unit (MES) and a offline detection unit (VCAST) are cooperated to work through the following steps:
firstly, an ECU engineer inputs ECU information on an interface in a manufacturing system (MES), wherein the data comprises a vehicle type, vehicle configuration, an ECU name of a part, an ECU software version of the part and an engineer mailbox; wherein the SAP number represents the model and the vehicle configuration, the 1 st bit of the SAP number represents the model, the 2 nd bit of the SAP number represents the vehicle configuration, and the ECU information is as follows in Table 1:
TABLE 1ECU information Table
| Identification | Parameter(s) |
| Vehicle model | A |
| Vehicle arrangement | H/M/L |
| Name(s) | TBOX |
| Software version | LN-G80T2-CA |
| Mail box | ECU Engineer mailbox number |
Further, the loading unit generates loading information according to the number and configuration conditions of the vehicles ordered by the client and the dealer, and the loading information data is as follows in table 2:
TABLE 2 Loading information data sheet
| VIN | SAP No. |
| LEFDJ3BB1FTP1690K | AH0058845434 |
| … | … |
After the loading information is submitted in the loading unit, the loading information is sent to a manufacturing system (MES) through data transmission between the servers.
Further, after receiving the loading information of the loading unit (SAP), the manufacturing unit (MES) searches the vehicle type data of the ECU information according to the first part of the SAP number in the loading information, finds the data suitable for the vehicle type, and then searches the vehicle configuration data of the ECU information according to the second part of the SAP number, and generates the production information of the vehicle. The production information includes: vehicle VIN, vehicle SAP number, vehicle ECU Name (ECU Name) and ECU Software version (ECU Software) and ECU engineer mailbox: meanwhile, the vehicle production information is pushed to a offline detection unit (VCAST) ECU information table 3:
TABLE 3ECU information Table
Further, a down-line detection unit (VCAST) unit stores vehicle production information sent by a manufacturing unit (MES). After the vehicle storage battery is installed and the vehicle is assembled, when the offline detection unit is connected with the vehicle through the vehicle OBD port to perform vehicle offline detection, vehicle information is read through a UDS (Universal data System) diagnosis command, and the vehicle information comprises: vehicle VIN and all ECU names and corresponding ECU software versions. The offline detection unit (VCAST) acquires the vehicle information as follows:
TABLE 4 offline detection Unit acquisition datasheet
| VIN | LEFDJ3BB1FTP1690K |
| Source | Vehicle information |
| ECU1 Name | PEPS |
| ECU1 Software | LN-G85T-BA |
| ECU1 Name | TBOX |
| ECU1 Software | LN-G80T2-BA |
| … | … |
Further, the offline detection unit (VCAST) matches the vehicle production information transmitted from the manufacturing unit (MES) with the vehicle information read from the vehicle, as shown in table 5 below:
TABLE 5VCAST and MES vehicle information matching Table
Matching the VIN of the vehicle production information according to the VIN in the vehicle information; and finding the data of the ECU Name of the vehicle information according to the data of the ECU Name of the vehicle production information, and comparing the ECU Software of the vehicle production information with the ECU Software of the vehicle information. If the vehicle production information of the same VIN is consistent with the ECU Name and ECU Software data of the vehicle information, the vehicle is normally off-line, and the off-line detection unit (VCAST) feeds back the detection result information of the VIN to the manufacturing unit (MES). If the value of the ECU Name is not found in the vehicle information or the value of the ECU Software does not match with the value in the vehicle production information, the VCAST unit intercepts the vehicle with the problem and prompts the failure of the matching of the vehicle Software on the offline device, and simultaneously the VCAST unit feeds back the VIN of the corresponding vehicle and the detection result information of the failure reason to the MES unit, wherein the feedback data are shown in the following table 6:
TABLE 6VCAST test result feedback Table
And finally, a manufacturing system (MES) analyzes the vehicle detection result information transmitted from the VCAST unit, if the vehicle detection result is inconsistent, the MES unit finds a matched engineer mailbox according to the ECU which fails in detection and synchronously transmits the failure reason to an ECU engineer for processing, and the vehicle can not be normally off-line until the vehicle data read by the VCAST unit is consistent with the ECU Name and ECU Software data of the vehicle of the MES unit.
In summary, the present invention provides an apparatus and a method for matching and detecting vehicle ECU software, wherein according to the ECU information firstly confirmed by an ECU engineer, the information finally generated after the vehicle passes through the information matching of the loading unit and the manufacturing unit reaches the offline detection unit and is compared with the ECU information confirmed by the ECU engineer in advance, and the ECU engineer checks the vehicle when the vehicle detection result is wrong, so as to ensure that the ECU information is correct, thereby avoiding the problems of human errors in the vehicle production process, the error of the produced vehicle ECU software, the functional defects and the economic loss.
