Controlling Motion Sickness in Autonomous Vehicles Through Active Suspension Tuning

Quick fact

Humans are most sensitive to accelerations below 1 Hz, and these low-frequency motions are exactly what active suspension systems are tuned to reduce, potentially cutting motion sickness incidence by up to 40% in simulated studies.
