Product Code:SAE J2461
Title:Vehicle Electronic Programming Stations (VEPS) System Specification for Win32 TM
Issuing Committee:Truck And Bus Low Speed Communication Network Committee
Scope:IdentificationSAE J2461 specifies the recommended practices of a Vehicle Electronics Programming Stations (VEPS) architecture.in aWin32? environment. This system specification, SAE J2461, was a revision of the requirements for Vehicle Electronics Programming Stations (VEPS) set forth in SAE J2214, Vehicle Electronics Programming Stations (VEPS) System Specification for Programming Components at OEM Assembly Plants (Cancelled Jun 2004). The J2214 standard has been cancelled indicating that it isno longer needed or relevant.IntroductionSAE J2461 describes the application of the Win32? environment to the customization of programmable componentsassembled in OEM vehicles, where components provide a communication API such as TMC RP1210B. Because thecustomization is performed using both OEM-provided and vendor-provided software, the roles and responsibilities of thevendor and OEM elements must be defined to permit the development of common vendor software elements for allOriginal Equipment Manufacturers (OEMs).SAE J2461 identifies the system resources of a Win32 TM computer between OEM and vendor components, the required elements comprising VEPS, and specifies the software interfaces needed between the OEM-supplied elements and the vendor-supplied elements. By maintaining many common elements with SAE J2214, an orderly transition from a MS-DOS TM based VEPS to a Win32 TM VEPS can be achieved. SAE J2286 is the software interface element of SAE J2214 that specifies the Vendor Component Program Data File Interface for OEM Assembly Operations. SAE J2286 will still be the Data File Interface used for the Win32 TM VEPS. TMC RP1210 describes the communication API used by the vendor programs.BackgroundThe OEMs typically are horizontally integrated. Each major vehicle component has multiple vendors who compete forcomponent sales in OEM markets. Customer orders determine a set of components from this variety to meet thevehicle’s desired performance requirements. Customization and calibration of these components for the vehicle’sapplication necessitates the need for a standard method to perform this programming without causing the OEM to installspecial VEPS for each vendor component. Hence the existence of MS-DOS? SAE J2214. As the need for moreapplications grow at OEM VEPS, a more flexible solution to the current RP is needed. Win32? SAE J2461 providessuch a solution.
