To provide a drive diagnosis device, a drive diagnosis system, a drive diagnosis method, and a program that are capable of reliably determining whether or not a vehicle is traveling while expanding in a direction opposite to the direction indicated by a blinker lever.SOLUTION: A drive diagnosis device comprises a drive diagnosis unit. Under a condition that a blinker lever of a vehicle 30 has been moved to a predetermined position and a vehicle is traveling forward, when an absolute value of a cumulative value of a yaw-angle of the vehicle in a direction indicated by the blinker lever is equal to a first threshold value or less, and when an absolute value of a steering angle of a steering wheel of the vehicle indicates that the steering wheel has rotated by a second threshold value or more in a direction opposite to the direction indicated by the blinker lever, the drive diagnosis unit determines that the vehicle is traveling while expanding in the opposite direction at a cross point Is.SELECTED DRAWING: Figure 6

    【課題】車両が交差点をウインカーレバーが示す方向と反対方向にふくらみながら走行しているか否かを正確に判定可能な運転診断装置、運転診断システム、運転診断方法及びプログラムを提供する。【解決手段】車両30のウインカーレバーが所定位置へ移動し且つ車両が前進走行している条件下において、ウインカーレバーが表す方向の車両のヨー角の累積値の絶対値が第1閾値以下であり、且つ、車両のステアリングホイールの操舵角の絶対値が、ステアリングホイールがウインカーレバーが表す方向と反対方向に第2閾値以上回転したことを表すときに、車両が交差点Isを反対方向にふくらみながら走行していると判定する運転診断部を備える。【選択図】図6
