Research & Development Support for Autonomous Vehicle Design

⇠ Back to Automotive

Automotive-BG

RTI provides an efficient path for development, from research to proof-of-concept, and into production. With support for over 100 hardware platforms and a transport-agnostic design, RTI Connext Drive enables fast integration and portability of applications from prototype to production, without the need to modify application code or change the network architecture. Connext Drive can help users get their designs to market faster and reduce the total cost of production development.

Based on the Data Distribution Service (DDS™) standard, Connext Drive has been designed to handle both the early stages of development when requirements continue to change, as well as the more complex requirements of production-grade development. Customers depend on RTI to smooth the transition and deliver a connectivity framework that can meet development needs now, and into the future.

Use Cases / Features

Use Case Feature Value

Multiple Collaborative Teams

Common Data Model

Teams can collaborate using a common interface definition that enforces interoperability, which reduces time spent debugging changes in configuration and application interoperability

Evolving Data Models

Extensible Types (DDS X-Types™)

Maintains interoperability between subsystems over time, regardless of  differences in the data model. Reduces the cost of integration and ensures long-term compatibility of your product versions

Heterogeneous or Unknown Hardware Platform

Extensive Platform and Transport Support

Applications can be moved between different operating systems and hardware platforms, and negotiate different transport protocols without any code changes

Modular Development

Data-centric Architecture

Applications depend only on the data interface and not on the behavior of other modules, which reduces the cost and complexity of maintaining a system

Scalable

Peer-to-Peer, broker-less, server-less

Proven capability to scale from small proof-of-concepts to very large systems with 100,000s of data points

Reusing IP in new projects and production

Robust, future-proof architecture

Applications can be migrated seamlessly to production development, as well as to new projects

Support for AUTOSAR

AUTOSAR and DDS are two software standards that were designed for flexible, scalable architectures, and they are fully compatible. AUTOSAR is the standardized automotive open system architecture designed for automotive Electronic Control Units (ECUs). Two AUTOSAR platforms – AUTOSAR Classic and AUTOSAR Adaptive – provide a layered software architecture approach for different vehicle use cases.

Now, these powerful standards work together to enable interoperability and advanced functionality for the industry. Together, AUTOSAR and DDS provide R&D automotive teams with a high-performance approach to designing and operating next-generation vehicles.

The new RTI Connext Integration Toolkit for AUTOSAR platforms, introduced in November 2023, provides developers with code generation and templates to integrate DDS connectivity in their AUTOSAR designs. This saves dozens of hours of custom development work and reduces development costs, while preserving performance and AUTOSAR methodology alignment.

For more information, see RTI Connext Integration Toolkits for AUTOSAR.

AUTOSAR Adaptive

AUTOSAR Adaptive defines a DDS network binding to support autonomous systems with a production-ready communications framework that delivers the reliability, scalability and performance required for complex systems.

AUTOSAR Classic

AUTOSAR Classic can be easily integrated with Connext Drive product components by using RTI’s Connext Integration Toolkit for AUTOSAR Classic. It supports automatic conversion of data type definitions across standard formats (OMG® IDL, OMG DDS-XML and AUTOSAR ARXML). The Toolkit also generates supporting C code for data conversion and marshaling between the Runtime Environment (RTE) and DDS communication frameworks.

Support for ROS 2

RTI applications support the ROS 2 open source project. Connext Drive provides the Robotic Operating System (ROS) community with a proven connectivity platform that is interoperable with other DDS implementations, is scalable, has robust security, and is proven in multi-billion dollar production environments.
