Abstract
Disclosed is a turning radius calculation method including: expressing a steering system model by means of relational expressions having a steering angle and turning angles of outer and inner tires as variables and including known parameters and unknown parameters; entering data on the known parameters based on design data; calculating the unknown parameters from the relational expressions corresponding to a zero-steering state and the relational expressions corresponding to a full-steering state; calculating turning angles of outer and inner tires respectively corresponding to a plurality of steering angles between the zero-steering state and the full-steering state using the relational expressions where calculated data on the unknown parameters are entered; calculating turning radii corresponding to the calculated turning angles of the outer and inner tires; and calculating an approximate function of turning radius for steering angle based on the plurality of steering angles and the turning radii.
