The driver's response to vehicle motion is an important consideration when developing an advanced vehicle control system. The electric active suspension used in this investigation was a rotary type electric active suspension that could control roll, pitch and bounce. The system can control of vehicle attitude and ride comfort based on an inertia input and road input with 'sky-hook' control logic. A control logic for vehicle attitude and ride comfort control of an active suspension was developed. 1. Ride comfort control: Adding FF control to FB 'sky-hook' control, a compounded 'sky-hook' control was developed and a reasonable effect on the displacement ratio and ride comfort was confirmed. Actuator response delay was addressed by preview control that reduced the higher frequency phase lag. Improved ride comfort performance was confirmed in the comparatively higher frequency range between 2 and 9 Hz. 2. Relationship between driver's response and roll attitude: During smaller vehicle roll motions, the head roll angles become smaller, and the difference among the examinees' head movement angles was in a small range. Lateral acceleration is a variable that contributes to head roll angles in absolute coordinate system. The lateral acceleration time derivative (jerk) and the head roll angle velocity have a linear relationship. More detailed research on vehicle motion control and driver response is required to gain a clearer understanding of their interplay. Kinematical vehicle control effects on drivers should be considered in the system development.
