Abstract : Software Sharing in automotive embedded software development has continuously grown over the last decades and is still getting more importance and attention. Main advantages for Software Sharing, as seen by the OEM, are acceleration of development time and cycle as well as a full flexibility to customize the final product, with introduction of its own software. Although classic software sharing has shown its capabilities in practice, it shows some limitations and need to be extended in order to cover additional use cases. The concept of Model Sharing can help to address those use cases and enhance OEM - Tier1 cooperation. Bosch has established with this approach a five-level classification for Model Sharing between Tier1 and OEM, which starts from -Use of ECU virtualization environment- and goes up to -Joint Development-. Use of Standards for the data description e.g. ASAM with -MDX, CDF …- and-or AUTOSAR with service libraries, methodology … as well as standardized interfaces specifications e.g. as published with AUTOSAR R4.x can significantly increase the effectiveness of this approach; e.g. by easing labels data management and exchange between development partners through a database as well as exchange of models.
