Eclipse Chariott

Eclipse Chariott is an Eclipse Foundation project that defines a software-defined vehicle (SDV) service architecture and related tooling for managing and orchestrating vehicle-centric services across cloud and in-vehicle environments (software-defined vehicle / automotive middleware).

  • Service-Based Architecture (SBA) for software-defined vehicles (software-defined vehicle / service architecture)
  • Abstraction and orchestration of vehicle functions as services across cloud and edge (orchestration / edge-to-cloud)
  • Support for building, deploying, and managing SDV applications and services (application platform)
  • Interfaces and patterns for integrating vehicle data and functions into backend systems (systems integration)
  • Eclipse Foundation governance and alignment with Eclipse automotive and SDV initiatives (open-source ecosystem)

More About Eclipse Chariott

Eclipse Chariott is a project under the Eclipse Foundation automotive portfolio that focuses on a Service Oriented Architecture (SOA) for software-defined vehicles (software-defined vehicle / service architecture). The project targets the problem space of managing vehicle capabilities as services that can be discovered, orchestrated, and consumed consistently across in-vehicle platforms and cloud backends. It addresses scenarios where vehicle functions need to be exposed as standardized services to applications, Original Equipment Manufacturer (OEM) backends, and partner ecosystems.

The project centers on defining an architecture in which vehicle features, such as access to data signals or control functions, are encapsulated as services (vehicle services) that can be managed through a common runtime and interface model (application platform). Within this model, Chariott provides concepts and components for service registration, discovery, and invocation across distributed environments that include embedded ECUs, in-vehicle compute platforms, and cloud-based systems (orchestration / edge-to-cloud). This supports deployment and lifecycle patterns where services may run in-vehicle, in the cloud, or in both locations with a consistent access model.

For enterprise and OEM environments, Eclipse Chariott offers a structured way to integrate vehicle services into backend architectures, such as fleet management systems, data platforms, or mobility applications (systems integration). By exposing vehicle capabilities through defined interfaces and service contracts, organizations can connect SDV services to existing identity, telemetry, analytics, and business process components without tight coupling to individual ECUs or proprietary stacks. This supports modular service composition, policy enforcement, and monitoring based on well-defined service boundaries.

Eclipse Chariott is aligned with the broader Eclipse software-defined vehicle initiative and related automotive projects within the Eclipse Foundation (open-source ecosystem). Its architecture and concepts are designed to interoperate with other SDV building blocks from the same ecosystem, including in-vehicle middleware, cloud toolchains, and developer frameworks, so that Chariott can function as a coordination and abstraction layer rather than a monolithic platform. This positioning places the project within categories such as SDV service orchestration, automotive middleware, and edge-to-cloud integration for vehicle fleets.

From an operational standpoint, Eclipse Chariott focuses on clear separation between service definition, deployment location, and consumption (service architecture / operations). This enables enterprises to define vehicle-related services once and deploy them in different environments as required by latency, safety, or regulatory constraints. It also provides a basis for governance models where OEMs or fleet operators can manage which services are available to which consumers, and how those services evolve over time, within the boundaries of the Eclipse Foundation’s open development and specification processes.
