MOST in Driver Assistance
This article gives evidence supporting the need for seamless integration of infotainment and driver assistance. Both hard real-time and high bandwidth requirements must be met. A multi-channel network approach with inherent synchronicity will be the first choice. If then additional advantages such as maturity, cost efficiency and flexible topology come along with an appropriate safety integrity level, MOST is proven to fit best from a system solution perspective.
  • of standardized commands that allow for synchronized message and event flow.
  • MOST provides an IP (intellectual property) pool with royalty-free cross-licensing among the members of the MOST Cooperation. It allows for a straightforward, easy grant of license which is based on compliance testing. This model, as well as the technology, is attractive for both premium and volume carmakers.
  • Established compliance processes with accredited MOST Compliance Test Houses according to ISO 17025 [6] leads to pre-tested components. In addition, the compliance verification program closes the design feedback loop and thus helps to continuously improve the standard.

Conclusion

This contribution has shown that a flexible multi-channel approach like MOST will provide an overall optimal system solution meeting the requirements of infotainment and driver assistance as they grow together and face higher bandwidth needs.

Applications where the attention of the driver is shared will especially require an appropriate network that supports an easy and seamless integration of infotainment and driver assistance domains. MOST Technology is being developed by automotive series developers and driven by the OEMs. It meets these automotive requirements.

Starting with the new generation – MOST150 – and providing a deliberate roadmap, MOST Technology is resilient and future-proof. It will be prepared for the challenges to come.
