The BMW Group is using basic software (BSW) from Vector for the reference implementation of the “BAC 3.0” BMW AUTOSAR Core. It contains BSW modules defined in AUTOSAR Release 3.0 for the CAN, LIN and FlexRay bus systems, memory management, system services and the operating system. These modules, optimized for low RAM, ROM and execution time, are already being used in many ECU projects. Therefore, they have a high level of maturity. ECU suppliers benefit from shorter development times due to reduced integration and testing effort.
