Full Description

SAE J2461 specifies the recommended practices of a Vehicle Electronics Programming Stations (VEPS) architecture in a Win32sT 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). SAE J22214 standard has been cancelled indicating that it is no longer needed or relevant.

SAE J 2461 describes the application of the Win32sT environment to the customization of programmable components assembled in OEM vehicles, where components provide a communication API such as TMC RP120. Because the customization is performed using both OEM-provided and vendor-provided software, the roles and responsibilities of the vendor and OEM elements must be defined to permit the development of common vendor software elements for all Original Equipment Manufacturers (OEMs).

SAE J 2461 identifies the system resources of a Win32sT 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 J 2214, an orderly transition from a MS-DOSsT based VEPS to a Win32sT VEPS can be achieved. SAE J 2286 is the software interface element of SAE J 2214 that specifies the Vendor Component Program Data File Interface for OEM Assembly Operations. SAE J 2286 will still be the Data File Interface used for the Win32sT VEPS. TMC RP1210 describes the communication API used by the vendor programs.

The OEMs typically are horizontally integrated. Each major vehicle component has multiple vendors who compete for component sales in OEM markets. Customer orders determine a set of components from this variety to meet the vehicle's desired performance requirements. Customization and calibration of these components for the vehicle's application necessitates the need for a standard method to perform this programming without causing the OEM to install special VEPS for each vendor component. Hence the existence of MS-DOSsT SSAE J2214. As the need for more applications grow at OEM VEPS, a more flexible solution to the current RP is needed. Win32sT SAE J 2461 provides such a solution.
