Abstract
An object of the present invention is to execute an optimum control of vibrations due to a driver's operation of an accelerator pedal, steering wheel and brake pedal. The operation instructions are inputted into a vibration calculating means (kinetic model) comprising a vehicle body model, suspension model and tire model. Conventional kinetic model controlled the suspension in order to suppress the vehicle body vibration. However, in the kinetic model of the present invention, the tire vibration due to a change in the engine output is first absorbed by the suspension, whereby a residual vibration which was not be absorbed yet by the suspension is transferred to the vehicle body. The operation inputs are compensated by the three feed-back loops between the outputs of the above-mentioned three portions and input of the tire portion, giving the highest priority on the vehicle body model.
