To provide a system and a program which can provide an index for evaluating the responses (side slip and yaw motion) at the extremely early stage of the minute steering of a vehicle.SOLUTION: An index calculation system for calculating an index for evaluating the responses at the extremely early stage of the steering of a vehicle comprises: input reception means which receives at least the inputs of a mass m of the vehicle, load distributions (Wf:Wr) of front and rear wheels of the vehicle and a distance I between a shaft of the front wheel and a shaft of the rear wheel of the vehicle; and computing means which calculates a value equivalent to the yawing inertial moment around the center of percussion to the lateral force acting on the front wheel at the extremely early stage of the steering of the vehicle as an index on the basis of the input mass m, load distributions (Wf:Wr) and distance I.SELECTED DRAWING: Figure 10
【課題】 車両の微小な操舵極初期時の応答(横滑りとヨー運動の両方)を評価するための指標を提供することができるシステムやプログラムを提供すること。【解決手段】 指標算出システムは、車両の操舵極初期の応答を評価するための指標を算出するシステムであり、少なくとも、車両の質量mと、車両の前後輪の荷重配分(Wf:Wr)と、車両の前輪の軸と後輪の軸との間の距離lとの入力を受け付ける入力受付手段と、入力された質量mと荷重配分(Wf:Wr)と距離lとに基づき、車両の操舵極初期に前輪に作用する横力に対する撃心廻りのヨーイング慣性モーメントに相当する値を指標として算出する演算手段とを含む。【選択図】 図10
