Together, they present designers with a myriad of matrixed challenges.

The stakes for success are incredibly high, from the confidence of consumers and regulators to market innovation and even survival.

The primary challenges the industry is experiencing to advance the integration of SDV architectures are:

  • Clarifying the concept of what a software-defined vehicle means is a significant hurdle due to varying interpretations among OEMs
  • The challenge primarily revolves around establishing industry-standard hardware interfaces, vehicle APIs and data models
  • Enabling collaboration with a strong ecosystem that includes both new suppliers that provide unique capabilities, as well as integrating traditional supply chain vendors, all aimed to mitigate risk
  • Ensuring system scalability and future-proofing the vehicle architecture.

AI: What is your solution?

Lopez-Estepa:  RTI has launched Connext Drive 3.0, the latest product offering in our automotive line.

munications framework that adheres to the highest functional safety standards (ISO26262 ASIL D).

OEMs now have a flexible, accelerated path to certification that eliminates the need for recertification if the vehicle operating system or network interfaces change.

AI: Do you see the standardization of technology across manufacturers playing a crucial role in scaling electric and autonomous vehicles?

Lopez-Estepa:  The required transformation won’t occur until the industry defines its interfaces, standards and architectures.

The shift towards intelligent, connected, and autonomous vehicles demands a new level of sophistication in the design and integration of automotive software.

As vehicles become more complex and the interoperability of different suppliers needs to cooperate, the need for robust and efficient standard communication mechanisms across heterogeneous systems becomes paramount.

Technologies like the Data Distribution Service (DDS™) standard, AUTOSAR Classic, Adaptive and ROS 2 have emerged as critical enablers for building resilient and scalable automotive systems.

The other reason for industry to promote the use of standard technologies is the level of liability. The implementation of standard-based technologies facilitates supplier choice and eases the risk in the OEM’s eyes.

RTI is the leading provider of DDS and is in the position to ensure interoperability between all these technologies to accelerate time to market, reduce cost and optimize the needs of the industry.

RTI is an active member of AUTOSAR, AVCC®, COVESA, OMG® and SOAFEE, along with other leading automotive technology providers. The main goal of these organizations is to define what the new software-defined vehicle will look like.

AI: What technical path and business model requirements have you identified during RTI’s 20-year involvement with the DDS standard?

Lopez-Estepa:  RTI has the largest engineering team in the world dedicated to DDS, with professional services and global support to help drive project success.

This focus provides RTI customers with a communication framework that allows them to manage risk, while increasing the scalability, modularity and reusability of their solutions with the highest levels of safety and cybersecurity.

In the case of automotive, there is the need of dedicated software components for key software-defined vehicle (SDV) use cases: ECUs, zonal gateways, high performance compute in ADAS, digital cluster and vehicle control, as well as telematics, cloud implementations and OEM-specific applications.

RTI’s development processes for Connext Drive have been officially certified to ISO 26262 ASIL -D, offering manufacturers an accelerated path to building safety-critical systems for electric and autonomous vehicles.

The automotive industry has unique challenges in terms of business model, given the fact that the development of a given vehicle takes over half a decade and the business is centered around the volumes.

RTI has adapted its business model to align with the needs of the different industry players: OEMs, Tier-1s and Tier-2s, with an emphasis on the integration of safety and cybersecurity components.

Being located in Silicon Valley, RTI has extensive experience in developing mission-critical systems across various industries.

AI: How do the challenges in the electric and autonomous vehicle space compare to those in other sectors such as Healthcare, Energy, Industrial Automation, and Aerospace and Defense?

Lopez-Estepa:  While the principle around mission-critical systems might be similar, each industry has a level of differentiation that makes them unique.

RTI has been able to benefit from an extensive mission-critical culture that accelerates the transition towards automotive systems.

Nevertheless, a large level of investment was required to create an automotive solution.

RTI has created a dedicated product line in automotive to satisfy the needs of the industry. This includes dedicated product development processes to comply with automotive specifications as well as a rich set of products that can be effectively contextualized into the different architectural components.
