Consideration of a human dynamic characteristic and performance evaluation of an electric active suspension

A rotary actuator type electric active suspension system, adopted for the investigation, enable to control roll, pitch, and bounce. The system allows controlling the vehicle attitude by an inertial input logic while sky-hook logic improves ride comfort. Actual vehicle motion control effects on the drivers’ reaction were investigated. Drivers’ reaction differences were examined on the slalom driving under the active suspension-produced small and large roll angles. A roll oscillation simulator is set up in order to investigate influence of the roll angle which side acceleration of cornering does not act on. The simulator is applied to analyze the drivers’ adjusting characteristics under several roll angles and to examine drivers’ movement optimization. Analyzed results and consideration of the human characteristics are reported in the active suspension mounted vehicle case and the simulator case.
