How Immersive Driving Simulators Help Car Makers

virtual-perception-magazineThere’s a uniquely human aspect to testing and developing new cars. Despite the quantifiable data available, a human driver is arguably the ultimate arbiter of how well a car handles and performs. Beyond subjective appeal, cars also have to be robust to withstand the unpredictable nature of human drivers. That’s a challenging element to model in a virtual world.

Driving simulators appear to offer the best of both worlds. They allow engineers and test drivers the opportunity to sample a car’s behavior first-hand and even how everyday drivers react to new technologies in a controlled and safe laboratory environment. Historically, car companies and simulator manufacturers have struggled to unlock this potential, but it seems the driving simulator may finally have come of age thanks to new technology.

Manipulating the senses

The effectiveness of a simulator depends entirely on its ability to manipulate a driver’s senses. Professional test drivers and vehicle dynamics engineers are quick to discern real world from virtual world experiences; they can pick up on very low levels of latency, so it’s vital that all the sensory cues – the sights, sounds and motions – are delivered at the right time.

The dynamics of road vehicles are characterized by short, sharp movements, as opposed to the low-frequency pillowing created by aircraft wings. Believe it or not, even the most agile fighter jet lags behind a family hatchback when it comes to directional changes.

In response to this, Ansible Motion has developed a unique ‘stratiform’ motion system, a multi-layered machinery and control strategy that is designed expressly for ground vehicle dynamics. This stratiform layout provides lateral and longitudinal movement in a defined X-Y stage, while the layers above generate the yaw, pitch, roll and Z-plane ‘bounce’ motions.

About Ansible Motion

Founded in 2009, Ansible Motion creates and deploys technology associated with the physical and logical simulation of human-directed vehicles. We offer a range of automotive Driver-in-the-Loop (DIL) simulators featuring advanced computational and mechanical performance capabilities, and industry-unique motion and immersion solutions that create compelling virtual worlds for drivers and product development engineers.

Ansible Motion DIL simulators are used by automotive and research organisations around the globe to place real people into direct contact with imagined vehicles, on-board systems and situations. Our DIL simulators are designed, built and developed at our factory and R&D Centre in Hethel, England.
