Overview
ISO 17215-2:2014 - part of the Video Communication Interface for Cameras (VCIC) family - specifies service discovery and control for automotive camera systems. Focused mainly on the OSI session (layer 5) and presentation (layer 6) responsibilities, this part defines how camera-related services are advertised, discovered, invoked and managed across vehicle networks. Discovery and control are implemented using SOME/IP (Scalable service oriented middlewire over IP). ISO 17215-2 uses the general terminology established in ISO 17215-1 and is designed to integrate with AUTOSAR-compatible architectures.
Key topics and technical requirements
- Service discovery protocol: Defines how service instances (e.g., camera streams, diagnostics or configuration services) are advertised and discovered on the vehicle IP network using SOME/IP-based Service Discovery (SD) mechanisms.
- Control and RPC behaviour: Specifies remote procedure call (RPC) semantics for invoking methods, request/response and fire-and-forget patterns, and how parameters and responses are carried.
- Presentation and serialization: Details parameter serialization, wire format and header conventions required to transport service messages reliably and interoperably.
- Packet format and headers: Describes SOME/IP header, PDU/wire format and payload structures used for service discovery and control messages.
- Runtime behaviour: Covers ECU-internal interfaces, SD communication flows, RPC communication flows and expected state transitions during service registration, subscription and notification.
- Terminology and conventions: Reuses OSI model conventions (ISO 7498-1, ISO/IEC 10731) and aligns with the broader ISO 17215 set for consistent definitions of services, methods, events, fields and instances.
Practical applications and who uses it
ISO 17215-2 is intended for anyone building or integrating automotive camera systems and middleware for advanced driver assistance and vehicle perception tasks. Typical users include:
- OEM system architects and vehicle integration teams designing multi-camera systems (e.g., 6–12 cameras per vehicle scenarios).
- Tier‑1 suppliers and camera module manufacturers implementing camera ECUs and middleware.
- Firmware, middleware and software developers implementing SOME/IP-based discovery, RPC, serialization and control logic.
- Test, validation and diagnostics engineers who verify service registration, discovery, subscription and runtime message flows.
- Architects ensuring AUTOSAR compatibility and future-proof integration with physical/data link layers defined in ISO 17215-4 or alternate transports.
