Quantification of Ride Comfort Using Musculoskeletal Mathematical Model Considering Vehicle Behavior

This research aims to quantify driver ride comfort due changes in damper characteristics between mode and sport mode, considering the vehicle’s inertial behavior. The of riding an automobile has been evaluated recent years on basis a subjective sensory evaluation given by driver. However, reflecting driving sensations design work improve is abstract nature difficult express theoretically. Therefore, we human body’s effects while scientifically quantifying driver’s behavior operating steering wheel motion using physical quantities. To this end, collected vehicle data capture system CAN IMU sensors. We also constructed three-dimensional musculoskeletal mathematical model simulate movements calculate power amount energy per unit time used for joints muscles body. Here, compare terms hardness. In are soft stability mild, but vibration from road not easily transmitted making lighter load other hand, hard comparatively better. Still, driver, which makes it easy be placed As result comparison, was found that most likely applied neck. relation neck joint can therefore treated as objective measure comfort.
