In this paper, I suggest a method of estimate half-car model’s roll capacity using the measured trace of kinematic roll center that is an instant center of velocity from a data of wheel motion, on fixed ground, with SPMD. The trace of roll center found out from proposed method, drew on the coordinate of reference fixed on the surface which called fixed centrode, and the trace of wheel drawn on the moving coordinate reference that fixed on a car body is called moving centrode. These are able to be seized the vehicle’s kinematical roll characteristic except compliance effects by bush of suspension system under the shape of fixed and moving centrodes. We verify availability of this paper with comparison between the roll center when suspension system geometry is given and another roll center using SPMD data which is proposed in this paper. Also, I compare with roll center which is measured from SPMD
