Testing and Simulation
Testing and Simulation
Our Modular Testing and Simulation Rigs, Physical and Virtual: Our lab has built many physical and digital twins over the years for simulation and testing purposes. Our current lab simulators use both physical, modular bucks and also digital XR spaces for visualization, modeling and testing.
Modular Interior Buck
Our real-world driving simulator — a modular, reconfigurable interior buck, based on a GM sedan — allows us to easily and rapidly change controls and parts to test out concepts. The beauty of this buck's design, based on our very first simulator, is that it can swap out production and 3D-printed interior surfaces and controls, and match production vehicles in H-Point and Ergonomics. The buck is designed such that we can switch interiors, from sedan to SUV, with corresponding interior components, in about an hour or so. Coupled with a 55" transparent OLED display with multi-touch capabilities, we can simulate an entire head-up display (HUD) windshield. Further, we can conduct a driving simulation with the buck and monitor the driver using eye tracking, biometric sensing, and time-to-task (performance) monitoring.
XR Driving Simulator
Our Virtual Driving simulator uses physical affordances for steering wheel and center stack (infotainment) redundancy, but is designed around a digital environment (either in headset or using a monitor). Our virtual simulator allows us to swap out entire cockpits and environments, road surfaces and conditions using VR headsets and video game engines (Unreal). Performance metrics, eye tracking and other measures can be done within headset or with cameras mounted to the simulator.
Motion Control
We recently built a 2-axis motion control simulator for the dynamic modeling of hover bikes, motorcycles, bicycles, and scooters. This motion control simulator can mimic the movements of two-wheeled vehicles or drones with ease, traversing over 120° in just 2 seconds. By understanding the dynamics of a two-wheeled vehicle (motorcycle), the lab can devise better control systems that improve rider safety and human performance.
