Quantifying Roll Feel of a Vehicle by Measurement of Driver’s Body Motion

This paper presents a study to quantify the difference in roll feel experienced by the driver with a change in damper characteristics between “comfort” and “sport” mode. The vehicle and driver’s motion are measured during the double lane change maneuver. In “sport” mode, the timing of steering operation was found to be faster (P = 0.0456), which can be explained by the driver being able to make quick upper body corrections to resist the slow vehicle roll motion. This difference in steering operation because of the man-machine feedback system can be considered as an objective measure to quantify roll feel.
