Embodiment 1

[0033] S1: Create a vehicle matrix in the TC system according to the vehicle design configuration. The input information includes vehicle BOM, tire model, tire standard inflation pressure, alarm pressure and the unique internal identification number VCB of each model, and the VCB number is related to the SAP system to associate.

[0034]S2: The customer places an order through the DMS system. After approval, the DMS system generates an order serial number, which includes the vehicle's unique internal identification number VCB number and option code, and transmits it to the SAP system.

[0035] S3: After receiving the order serial number, the SAP system matches the vehicle BOM and product special parameters from the TC system according to the VCB number. The special parameters include tire pressure, refrigerant filling amount, etc. Generate the final production BOM according to the option code and send it to the MES system.

[0036] S4: The MES system sends the production BOM ...

Abstract

The invention provides a tire pressure system test method applied to a multi-wheel commercial vehicle. The method comprises the following operation steps: S1, establishing a product database in a TC system; S2, the client placing an order through the DMS system and generates an order; S3, generating a product bill of material (BOM) in the SAP system; S4, monitoring the tire pressure in the tire production process through an MES system; S5, programming the whole vehicle data by using an EOL system; and S6, carrying out final detection on the vehicle. According to the invention, the labeled tireID is adopted, and the tire ID is written through scanning of the scanner, so that operation inconvenience and false activation caused by a low-frequency activation mode are avoided. Important data such as tire models, corresponding tire number and cold pressure in the vehicle model configuration table are sent to the EOL system in advance through the MES system, so that the part number redundancy is reduced, and the management is more convenient. The invention provides a more efficient method for monitoring the tire pressure of the multi-wheel commercial vehicle.

Description

technical field [0001] The invention relates to a tire pressure system testing method, in particular to a tire pressure system testing method applied to multi-wheel commercial vehicles, belonging to the technical field of automobiles. Background technique [0002] At present, traditional tire inflation pressure monitoring requires human identification, which is likely to cause personnel interference; traditional tire pressure alarm systems are commonly used in low-frequency activation methods, that is, antennas are arranged on the side of the production line, or low-frequency antennas are arranged on the side of the chassis near the sensor. Activate the sensor for the corresponding tire. The rear tire sensors of multi-wheeled commercial vehicles are relatively close to each other. This application method is inconvenient to operate and easily leads to misactivation. In addition, there are many types of foreign commercial vehicle tires. The same model can be matched with dif...
