Many of you have told us you are enjoying our latest Motion Series of articles. So we thought we’d introduce you to two key figures from our driving simulator motion team: Martijn de Mooij and Frank Drop.
Martijn de Mooij, our technical development manager, has worked for Cruden for over 13 years. He has built up extensive experience running motion tuning sessions with expert drivers at automotive OEMs and racing drivers in series such as Formula 1 and Formula E.“Most race car drivers are extremely susceptible to motion inputs, which is actually what makes them good racing drivers. The accelerations experienced in a simulator are never the same as in a real car. When converting accelerations from the vehicle model into motion cues that can be generated with a simulator, it is important to find out what the driver actually needs to feel the car. My philosophy is that we should primarily focus on replicating those accelerations that the driver needs to drive the virtual car as much on the limit just like they drive the actual car,” says Martijn.
Martijn’s thorough understanding of this process has been hugely valuable to our customers over the years. He knows how to translate the subjective feedback from drivers into a personalised motion cueing strategy. His experience in driver-centered cueing has enabled him to modify the classic cueing algorithm, optimizing it for driver-centered cues.
Earlier this year, Frank Drop joined Cruden as a simulator engineer. Previously, Frank worked as a research scientist at the Max Planck Institute for seven years, where he wrote a PhD thesis on anticipatory control behavior (feedforward) of humans in control of vehicles. The main research question answered by Frank’s thesis was: “How does a human control a vehicle?” This is the key question for anybody building or operating a driving simulator. Armed with a hefty amount of knowledge on filter-based motion cueing strategies, following his PhD, Frank spent four years researching and developing Model Predictive Control (MPC) based algorithms.
The experience of Martijn in tuning motion systems with expert drivers, combined with Frank’s theoretical background and scientific research ensures that every simulator leaving the Cruden workshop is tuned to perfection!
Our latest article on motion systems, co-authored by Martijn and with input from Frank, takes a look at the factors to consider when adding further degrees of freedom to increase the workspace in a driving simulator. It’s an often controversial topic and one we’re asked about a lot. Tell us what you think by first reading: here.
