Standards
• Open Services Gateway Initiative (OSGi)
– Open specifications for the delivery of managed broadband services to networks
in homes, cars and other environments.
– Architecture and specifications for core platform, vehicles, devices, remote
management and security
– Release 3 due March 2003
– Reference: www.osgi.org
• Automotive Multimedia Interface collaboration (AMI-C)
– Organization of motor vehicle manufactures created to facilitate the development
and standardization of automotive multimedia interfaces to motor vehicle
communication networks.
– Specifications for physical network interfaces, network protocols and In-vehicle
software interfaces (telematics and local)
– Release 2 specifications due Dec. 2002
– Reference: www.ami-c.org
• Java Community Process (JCP)
– Embedded Java VM.s with bolt on components and APIs
– Reference: www.jcp.org
OSGi - Overview
• Direction towards de-facto standard for 3rd generation
•
platforms
Operating system feature
–
–
–
–
–
Standard abstraction from HW w/Auto centric APIs.
Life cycle management for dynamic service deployment
Multi-tasking/function
Remote management
Java component model, security
• Integrates with back-end infrastructure.
• Faster time-to-market
– Reduction in platform implementation and sustaining costs.
OSGi - Overview
AMI-C
• Characteristic
– Vehicle control: Low-speed wired communication
– Information system: High-speed wired communication
