u Domain specific language and data model

u Single source model across all Automotive E/E development Use Cases:→ The model is the Single Point of Truth→ Mappings ensure full traceability→ The model can be analyzed by metrics

u All data objects have a semantic meaning→ Base for various model checks e.g. for

Correctness, Completeness, Consistency

u Automated algorithms for synthetization, scheduling, signal routing, etc.

Example of a Service Oriented Architecture


Want to know the weather of my current position!

I know the city code of one specific position

I know the weather for a city code

I can inform you the weather for your position

but I need help…

Service Interface (2/2)


A method represents a function that is executed by a provider on request of one or more consumer(s)

An event represents an update to a piece of data. The provider decides when to send this update and the occurrence of it is transmitted from a to one or more consumer(s).

A property (field, attribute) represents a piece of data hosted by a provider that exposes to one or more consumer(s) a get and/or a set method. Consumers can optionally receive notifications of changes of the field’s value.

Summary – SOA & Ethernet @ PREEvision

Summary

u Service oriented Architectures (SOAs) provide flexible, open and dynamic distributed systems.

u They are enablers for

u Connectivity and Autonomous Driving

u SW Update, SW Upgrade and Vehicle Service in the field

u New Building Set Strategies and Handling of Variants.

u Future E/E Architectures will combine the strengths of Signal Oriented and Service oriented Architectures.

u AUTOSAR Adaptive and AUTOSAR Classic will be deployed in the same vehicle, even in the same ECU.

u PREEvision already supports the introduction of SOAs, the migration to SOAs and their implementation in

u AUTOSAR Classic

u AUTOSAR Adaptive

u Enhanced Ethernet and AUTOSAR capabilities coming with PREEvision 9.0

u AUTOSAR Adaptive

u DoIP & Diagnostic Communication Infrastructure

u Global Time Synchronization
