Stuttgart, Germany, June 5th , 2024 – VI-grade, the global provider of human-centric simulation-driven vehicle development solutions, today announced the launch of its Driver-in-Motion Full Spectrum (DiM FSS) Simulator, which was exclusively debuted at VI-grade’s ZERO PROTOTYPES Summit in May. This groundbreaking technology is a true game-changer in experimental simulation, earning VI-grade the Automotive Testing Technology International Award for “Hardware Innovation of the Year.” This prestigious award was presented to VI-grade on June 4th at the 2024 Automotive Testing Expo in Stuttgart, Germany.
The Driver-in-Motion Full Spectrum Dynamic Simulator (DiM FSS) is a real-time, Driver-in-the-Loop simulator that offers a comprehensive experience of accurate motion, vibration, and sound over a complete spectrum from 0 to 20kHz. It is the first simulator capable of generating full vehicle motion with 9 degrees of freedom over a multi-meter workspace, paired with precise sound and vibration, creating a fully immersive experience. This innovation results from VI-grade's proven expertise in vehicle dynamics and NVH (Noise, Vibration, and Harshness) simulation.
Historically, vehicle dynamics and NVH evaluations were conducted separately, even though driving integrates dynamics, ride quality, sound, and vibration. The most effective evaluation method combines these elements into a single simulation. The DiM FSS addresses this unmet demand through its multi-stage system, capturing vehicle dynamics, motion, vibration, and sound for a holistic, realistic experience.
To achieve this, the DiM FSS utilizes a three-stage approach:
Lower Stage: Delivers primary vehicle motion.
Middle Stage: Provides full 6 DOF motion.
Hyperdock Stage: Features a highly optimized carbon-fiber cockpit that delivers high-frequency vibration through transducers at key driver touchpoints, while sound is provided through in-cockpit speakers or headphones.
This innovative design reduces mass, increases structural stiffness, and enhances overall simulation performance, providing the most immersive environment for multi-attribute evaluation. Additionally, all VI-grade actuator-based and cable-driven dynamic simulators can be upgraded with the new Hyperdock.
"I am thrilled to announce the launch of our DiM FSS Simulator, marking a significant advancement in our multi-attribute journey," commented David Bogema, Senior Director, Product Management at VI-grade. "The DiM FSS Simulator represents a quantum leap in experimental simulation, seamlessly integrating vehicle dynamics, motion, vibration, and sound into one immersive experience. We are also proud of the rapid commercial success it has already achieved. Two units have already been sold, with the first one to be delivered to our customer in a few weeks."
