Volkswagen Selects RTI's Real-Time Messaging Middleware for Driver Assistance Applications

RTI Data Distribution Service provides innovative integration solution for Volkswagen's next generation automotive network design

Real-Time Innovations (RTI), The Real-Time Middleware Experts, today announced that Volkswagen AG, Electronics and Vehicle Research department, is using RTI’s real-time messaging middleware across different projects to integrate advanced driver assistance systems into the car. These control systems need very high bandwidth to handle fast streaming data, coupled with low-latency command throughput for driver assistance. RTI Data Distribution Service will be used by Volkswagen to investigate a new network topology which facilitates integration of the high-speed network requirements of this innovative driver assistance system with existing low-bandwidth in-car networks.

Volkswagen’s advanced driver assistance systems must integrate, in real-time, complex environment perception algorithms which require the use of a high-bandwidth network. By contrast, existing in-car networks are focused on low-bandwidth, low-latency command oriented sub-systems, for example for communication between braking systems and the powertrain.

RTI Data Distribution Service provides a high-performance messaging infrastructure that allows Volkswagen to ensure real-time prioritization of critical operations and data across its new driver assistance network and the existing in-car control network, in spite of the very different characteristics of the two networks.

“We are very excited to be involved in this pioneering work in driver assistance design by an industry leader like Volkswagen,” commented David Barnett, vice president of Marketing at RTI. “RTI’s middleware was designed specifically to meet a wide range of real-time, inter-system communication demands and has achieved industry leadership in the defense sector, which have similar real-time and mission-critical communication requirements. Now our proven technology is being applied to the new challenges of next-generation automotive systems designs.”

About RTI Data Distribution Service

RTI's high-performance messaging and data distribution software enables the development and integration of distributed applications that require low-latency, high-throughput, high-scalability, deterministic responses and minimal consumption of network, processor and memory resources. RTI meets the unique and demanding requirements of mission-critical real-time systems, including the ability to run in dynamic and autonomous environments and over unreliable or low-bandwidth networks such as wireless and satellite links. RTI middleware was the first to comply with the DDS standards for application programming interface (API) portability and wire interoperability. RTI is the world's leading supplier of DDS-related software and services.
