Real-Time Innovations (RTI) has launched a communications framework that bridges the gap between AUTOSAR and publish/subscribe architectures for software defied and self-driving vehicles.

RTI has been a leader in the development of the Data Distribution Service (DDS) publish/subscribe standard and this is used for the latest Connext Drive 3.0 framework. The software has already been used in trials of autonomous racing cars.

The latest framework provides a path between functional safety and new software defined architectures with more than 25 companies who use Connext to accelerate their development programmes.

RTI Connext Drive 3.0 is the first platform-independent publish/subscribe framework to be certified by TUV SUD to ISO26262 ASIL D and bridges the platform gap between DDS, AUTOSAR Classic, AUTOSAR Adaptive and ROS 2. This allows OEMs to use the same framework from prototype to production. The publish/subscribe approach allows hardware and software modules to be added with the minimum of custom communication and integration code.

The certified software also eliminates the need for recertification if the vehicle operating system or network interfaces change. 

 Included with Connext Drive, the RTI Connext Integration Toolkit for AUTOSAR Classic speeds development through automatic conversion of data type definitions across standard formats (OMG® IDL, OMG DDS-XML and AUTOSAR ARXML) and generates C code for data conversion and marshaling between the runtime environment (RTE) and DDS communication frameworks.

The DDS standard is included in the AUTOSAR Adaptive specification, enabling OEMs to meet the demanding requirements for High Performance Compute (HPC). Included with Connext Drive, the RTI Connext Integration Toolkit for AUTOSAR Adaptive provides a code generator for application-specific DDS Network Binding assets plus a library implementing the AUTOSAR Communications Management DDS Network Binding. This allows developers to use additional technologies outside the AUTOSAR specification.

“There’s a growing need for auto manufacturers to reduce risk and accelerate production-readiness through safety-certified software,” said Andrew Longhurst, Managing Director at WITTENSTEIN high integrity systems in the UK.

“We see how the release of Connext Drive 3.0 can meet these requirements at the highest level, as it now includes a platform-independent footprint with ASIL-D compliance that facilitates the integration with SAFERTOS, our safety critical real-time operating system. Connext Drive, running alongside SAFERTOS, provides OEMs with the rigorous performance and safety needed for their production vehicles worldwide.”

“Based on our rigorous and approved ISO26262 verification processes, Verocel has demonstrated that the latest version of RTI Connext Cert within Connext Drive 3.0 complies with ISO 26262 ASIL-D requirements,” said Jim Chelini, President and CEO at Verocel.

“Over the course of several months, our teams conducted thorough code reviews, analysis, documentation and testing, and were able to generate full traceability mapping between all related lifecycle artifacts. Automotive software architects can confidently leverage Connext Drive 3.0 to clear regulatory hurdles for their embedded safety-critical automotive applications.”

“Connext Drive 3.0 enables manufacturers to create safer, more flexible and adaptable communication architectures with less risk,” said Pedro Lopez Estepa, Director of Automotive at RTI.

“Our customers now have an optimal way to enable vehicle communication as their platform evolves because of our latest platform-independent solution. The communication is not limited to DDS, as Connext Drive provides interoperable solutions with AUTOSAR Classic, AUTOSAR Adaptive and ROS. Connext Drive paves the way for the next generation of software-defined vehicles and empowers manufacturers to innovate fearlessly while accelerating success.”
