Abstract


  • In this paper, an integrated vehicle seat and sus5

    pension control strategy for a quarter car with driver model

    6 is proposed to improve suspension performance on driver ride

    7 comfort. An integrated seat and suspension model that includes

    8 a quarter-car suspension, a seat suspension, and a 4-degree-of9

    freedom (DOM) driver body model is presented first. This in10

    tegrated model provides a platform to evaluate ride comfort

    11 performance in terms of driver head acceleration responses under

    12 typical road disturbances and to develop an integrated control

    13 of seat and car suspensions. Based on the integrated model, an

    14 H∞ state feedback controller is designed to minimize the driver

    15 head acceleration under road disturbances. Considering that state

    16 variables for a driver body model are not measurement available

    17 in practice, a static output feedback controller, which only uses

    18 measurable state variables, is designed. Further discussion on

    19 robust multiobjective controller design, which considers driver

    20 body parameter uncertainties, suspension stroke limitation, and

    21 road-holding properties, is also provided. Last, numerical simula22

    tions are conducted to evaluate the effectiveness of the proposed

    23 control strategy. The results show that the integrated seat and sus24

    pension control can effectively improve suspension ride comfort

    25 performance compared with the passive seat suspension, active

    26 seat suspension control, and active car suspension control.
