PURPOSE:To prevent the rapid change of behavior of a cab right after variation of a control parameter by a method wherein a variation amount of each control parameter is divided into a plurality of lots by a control parameter change eliminating means, and the change of each control parameter is eliminated by a plurality of control cycles. CONSTITUTION:A difference between each control parameter newly determined by a control change eliminating means 36 and each of control parameters hereto determined, i.e., a variation amount, is divided into a plurality of lots and the change of each control parameter is eliminated by a plurality of control cycles. Subsequently, from an amount of relative displacement of each mode of a car frame from a road surface an amount of relative displacement of a cab from a car frame and each control parameter the change of which is eliminated, a control amount of each mode of the cab is determined by a control amount calculating means 37. Finally, from a control amount of each mode of the cab, the control voltage of each oil amount control valve 16 is determined. From a control voltage and feedback voltage from an oil pressure sensor 17, each oil amount control valve 16 is driven and an oil amount of each hydraulic actuator 19 is regulated. |
