PROBLEM TO BE SOLVED: To correctly obtain the acceleration of a vehicle from a detection value of an acceleration sensor of a portable terminal in consideration of the change in an inclination angle of the portable terminal.SOLUTION: A program for a portable terminal 100 causes a central processing unit 110 to execute: static state determination processing for detecting the static state of the portable terminal 100 and calculating the installation angle of the portable terminal 100 with respect to an own vehicle where the portable terminal 100 is installed; forward movement determination processing for detecting the forward movement state of the own vehicle and calculating the rotation angle of the portable terminal 100 with respect to the movement direction of the own vehicle; processing for converting the acceleration detected by an acceleration sensor 122 into the acceleration of the own vehicle on the basis of the calculated installation angle of the portable terminal 100 and rotation angle of the portable terminal 100 with respect to the movement direction of the own vehicle; processing for detecting the change in the inclination angle of the portable terminal 100; and inclination change processing for correcting the acceleration of the own vehicle in a case where the change in the inclination angle of the portable terminal 100 is detected.SELECTED DRAWING: Figure 1

    【課題】携帯端末の傾斜角度の変化を考慮して、携帯端末の加速度センサの検出値から車両の加速度を正確に求める。【解決手段】携帯端末100用のプログラムは、携帯端末100の静止状態を検出し、携帯端末100が搭載された自車両に対する携帯端末100の設置角度を算出する静止判定処理と、自車両の直進状態を検出し、自車両の進行方向に対する携帯端末100の回転角を算出する直進判定処理と、算出した携帯端末100の設置角度および自車両の進行方向に対する携帯端末100の回転角に基づいて、加速度センサ122により検出された加速度を自車両の加速度に変換する処理と、携帯端末100の傾斜角度の変化を検知する処理と、携帯端末100の傾斜角度の変化が検知された場合に自車両の加速度を補正する傾斜変化処理とを、中央演算処理装置110に実行させる。【選択図】図1
