is a crucial product criteria on the Japanese market. Further activities of JasPar include interoperabi-

observation of the communication behavior of FlexRay at different (currently unspecified)
transmission rates.
18.9 Summary
Since , the major automotive companies have been striving for the deployment of standard
software modules in their applications to achieve an increased test coverage and higher reliability
requirements that can only be met if standardized modules are used at various system levels.
This chapter provided an overview of today's industry practices in standardized automotive sys-
tem software. Existing standards proposed by industry partnerships like OSEK/VDX, HIS, JasPar,
and AUTOSAR, and by standardization authorities like ISO have been presented. Of all presented
approaches, the AUTOSAR partnership which started off in May and aims at putting soft-
ware modules according to the AUTOSAR standard into production vehicles by (BMW and
Honda) [] turns out to be the most promising one.
This is on the one hand due to the fact that several of already approved standards used today (like
OSEK OS and COM, HIS CAN driver, and ISO transport layer and diagnostics) heavily inspired
thecorrespondingAUTOSARstandards,ensuringthattheAUTOSARstandardisbuiltonsolid
well-proven technology. On the other hand the AUTOSAR open standard has massive industrial
backup: All AUTOSAR core members including seven of the world's biggest vehicle manufacturers
who together account for about % of all vehicles produced are strongly committed to the project
and plan to release tested and veriied AUTOSAR . specifications together with the corresponding
conformance test specifications by September [].
