GM using hi-tech simulator for testing infotainment HMI

Engineers and designers at GM are focused on assuring drivers will keep their hands on the wheel and eyes on the road, while driving. That’s why GM has invested in an advanced driving simulation lab focused on validating the integration of new technologies for next-generation interiors.

The simulator, which has been operational for more than a year, helps designers, engineers and research teams develop and validate concepts designed to provide safe and smart infotainment technology.

The simulator uses seven high-definition Christie projectors – similar to those used in movie theaters – to display a virtual roadway and landscape on a 360 degree series of large theater-style screens. A vehicle body with a reconfigurable interior system with multiple LCD screens is placed in the center of the screen area.

The LCD screens are used to mock up future interior electronics layouts developed by GM’s design staff. Reconfigurable LCD screens provide maximum flexibility for designers and engineers to test concepts within hours of development.

The plug-and-play nature of the system allows the lab team to download interior layout concepts for review without having to cut tools or build physical interior models, providing faster validation at less cost. Additionally, GM gains better in-house research and understanding about the behavior of drivers in various scenarios.

During testing, a subject “drives” the vehicle with the interior concept design along a virtual road while being asked to conduct various tasks – such as accessing music from their mobile device or adjusting cabin temperature – while maintaining lane position at a predetermined speed.

The lab also tests the subject’s ability to decipher various gauge configurations to see whether font sizes, arrangements or other features could improve driver behavior and performance. The goal is to measure variation in operator speed and lane deviation by monitoring eye, foot and hand movement while they are completing various tasks. If a task results in unacceptable levels of driver performance, the design and engineering teams refine the concept to improve driver performance.

The company is using the simulator on future Chevrolet, Buick, Cadillac and GMC vehicles and OnStar technologies to maintain GM’s leadership in developing safe and smart in-vehicle technology solutions.

“Within the next nine to 18 months, GM will aggressively introduce a wide variety of in-vehicle infotainment solutions providing smart, intuitive and safe technologies that will improve the driving experience,” says Micky Bly, GM’s executive director of Electrical Architectures and Infotainment. “In bringing this technology to market, the one thing we never lose sight of is that driver safety remains our highest priority.”
