RTI boosts performance of ROS2 in software-defined vehicles

New Products |
By Nick Flaherty

Real-Time Innovations (RTI) has launched the latest version of its Connext Drive for software defined vehicles with custom middleware to cut the latency of designs using the Robotics Operating System (ROS2)

Connext Drive 2.0, based on a DDS publish-subscribe framework, now adds direct integrations into AUTOSAR Classic and ROS 2. This allows developers to add data-centric connectivity to their familiar ecosystem architectures. A publish-subscribe architecture allows additionally nodes to be easily added into a network without impacting on the latency or performance, and RTI has developed a production ready framework for developers.

This allows a faster start to build on existing, familiar platforms and eliminates the need for custom programming. It also minimizes overall system complexity and cost, while building a future-proof, evolving system that doesn’t compromise performance. 

New features in Connext Drive 2.0 include tools to bridge AUTOSAR Classic ECU modelling and configuration workflows. This simplifies the design and evolution of DDS-enabled automotive ECUs.

The Connext ROS 2 toolkit includes a growing library of tools that eases ROS2 and Connext Drive ecosystem integration, providing ROS 2 developers with a bridge to production-grade systems. Through this integration, users can cut latency in their ROS2 systems through a custom ROS Middleware Wrapper developed by RTI. 

The Connext Drive Launcher helps users design a vehicle according to a specific use case, including Next Generation E/E, ADAS, Teleoperations, Simulation or High Performance Compute. By selecting the optimal features for a specific use case, developers achieve increased productivity and accelerated time to market. Users can now ease project development with direct access to the full set of utilities, services and tools available in Connext Drive. 

Connext Drive 2.0 also includes components safety-certified to ASIL D levels by TUV SUD. This helps functional vehicle safety to the needs of each individual component, from the ECU to the Central Gateways and includes interoperability with two popular Real-Time Operating Systems: QNX for Safety over armv8; and AUTOSAR Classic OS implementation on Infineon TriCore/Aurix microcontrollers.

“RTI Connext Drive helps address a fundamental challenge for the vehicle of tomorrow by providing a data-centric architecture,” said Nelson Quintana, Head of the Infineon Automotive Silicon Valley Innovation Center (SVIC). “We recognize the value of such technology and look forward to expanding our cooperation with RTI to bring its DDS-based technology, combined with Infineon’s leading automotive microcontroller portfolio including the Aurix family, to enable next-generation E/E architectures.”

“Connext Drive 2.0 reinforces the market commitment from RTI by initiating a use-case driven product,” said Pedro Lopez Estepa, Market Development Director, Automotive at RTI. “At RTI, we’re dedicated to helping our customers overcome the current architectural limitations in automotive with a product that secures several annual releases including a long-term safety-certified modular solution to enable Autonomous and Electric Vehicle innovation.”

Connext Drive 2.0 is in production vehicles on the road in the US, Europe and Asia but is now available to a wider industrial audience.
