u … for Connectivity

u Completely new functions by flexible integration of services in the IT backend

u … for Autonomous Driving

u Communication from the vehicle to the IT backend and vice versa

u Creation of precise maps

u Predictive assistents based on precise maps

u Routing for vehicle fleets in the IT backend

u …

u … for SW Update, SW Upgrade and Service

for Vehicles in the Field

u SW update of single services

u SW update and upgrade for vehicles

in the field over the air

u Remote diagnostics

u …

u … for Variant and Building Set Strategies

u SW options can be implemented as services

(base service … premium service)

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.

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
