In recent years, it is reported that passenger's dynamics and sensibility are different from a driver. However, there are few researches about a suspension control which considers the dynamics of human body, and a sitting position. In this paper, an active suspension control method is developed to reduce a passenger's vibration and motion. First, a vehicle and passenger model including the dynamics of human body and the sitting position is constructed. Second, robust control system design method which uses the vertical acceleration of a passenger's head as one of evaluation functions, is proposed. In order to verify the effectiveness of the proposed control method, the simulation is carried out by using the full vehicle model which has an active suspension system. From the results, it was confirmed that in nearly the resonance frequency of vertical direction of the passenger's head, the proposed control method can reduce the passenger's vibration better than general control methods which use a vertical acceleration of the vehicle body as the evaluation function.
