The two companies will further improve the human machine interface (HMI) development platforms behind the digital cockpit concept. The digital cockpit consists of a number of different HMI platforms, each having a unique security level. These HMIs are powered by instrument clusters using different operating systems, which in turn make it harder to offer a single unified cockpit experience.
Green Hills and Qt have worked together to overcome this problem by integrating the Qt Automotive Suite framework with Green Hills’ INTEGRITY Multivisor virtualisation tools. This software combination helps integrate the HMI interfaces across multiple operating systems operating a different safety levels into one multicore solution, while remaining compliant to stringent automotive safety standards. The combination of Green Hills INTEGRITY RTOS and Qt Safe Renderer enables safety-critical display elements to be certified to ISO 26262.
The concept cockpit demo shown at CES was built with the Qt Automotive Suite to demonstrate interdomain graphics and data sharing.
