The effect of active suspension attitude control with additional vertical load control on improvement of vehicle stability was verified by numerical simulation with full vehicle 4 wheeled model while cornering on a sinusoidal single concave road. In this paper, comparative study between attitude control system without vertical load control and passive system was made. The followings were made clear. 1) By applying the active suspension control with additional vertical load control, steady-state cornering forces can be ensured as the results of a reduction of vertical load fluctuation. Therefore the fluctuation of yaw velocity can be minimized from 3.4 deg/s to 1.5 deg/s in whole frequency range of a road disturbance up to 10 Hz. And also the fluctuation of sideslip angle can be reduced. Thus it was verified that this system can improve the vehicle stability. 2) In case of 'additional vertical load control system', more slow responses which are good for both ride comfort and vehicle stability can be obtained, because suitable control for both vehicle body attitude and vertical load can be achieved.
