Qt Company and Green Hills: integrated automotive HMI platforms

The Qt Company and Green Hills Software have announced a collaboration to deliver the latest in HMI development platforms for integrated automotive digital cockpits, focused on production deployment. The automotive digital cockpit encompasses the majority of the HMI systems in today’s connected vehicles consisting of disparate systems of different safety levels. Furthermore, due to safety requirements, instrument clusters use operating systems built to higher standards of safety and security than those used in general in-vehicle infotainment systems. These different safety level requirements combined with the use of different operating systems makes it difficult for developers to create a unified cockpit experience.

To tackle this challenge, Qt has integrated its cross-platform Qt Automotive Suite framework with Green Hills safe and secure INTEGRITY Multivisor virtualisation offering to enable the integration of disparate HMI interfaces across multiple operating systems at different safety levels into a single multicore system while complying with the highest levels of automotive safety standards.

Green Hills INTEGRITY real-time operating system is the gold standard run-time foundation for safety/security-critical software in industrial, avionics, medical, automotive and railway. As an optional RTOS service, the INTEGRITY Multivisor secure virtualisation extension safely runs high level operating systems such as Linux and Android alongside real-time critical applications requiring safety and security, assuring freedom from interference with native speed performance and safe, secure inter-process communication.

The Green Hills INTEGRITY RTOS, when combined with the Qt Safe Renderer, enables ISO 26262 certification for important safety-critical display elements. Additionally, the Qt Safe Renderer, as part of the Qt Automotive Suite, enables designers and software engineers to use a single user interface toolkit to design, build and test digital cockpits across all HMI needs, independent of safety requirements, for a consistent user experience. Qt is the leading framework to enable developers to build both instrument clusters and centre stacks with a single toolkit. Advances in processing power, together with mature safe, secure hypervisor technology result in significant cost savings without compromising safety when integrated into a single system on a single multicore automotive SoC using this combination.

The concept cockpit demo, built with the Qt Automotive Suite, demonstrates interdomain graphics and data sharing. The Qt Automotive Suite is jointly developed by The Qt Company, KDAB and Luxoft.
