To provide an inter-vehicle distance control device which can reduce arithmetic processing of inter-vehicle distance control for preceding vehicle group.SOLUTION: An inter-vehicle distance control device for controlling inter-vehicle distance between an own vehicle and a preceding vehicle, comprises: a preceding vehicle recognition part which recognizes a preceding vehicle group which contains a preceding vehicle on the basis of a pick-up image of a front camera of the own vehicle, a preceding vehicle pixel amount calculation part which calculates a preceding vehicle pixel amount which is a pixel amount of the preceding vehicle group in the pick-up image, an appropriate pixel amount calculation part which calculates appropriate pixel amount of the preceding vehicle in the pick-up image on the basis of preset setting vehicle speed or present vehicle speed, preset inter-vehicle distance and a recognition result of the preceding vehicle group obtained by the preceding vehicle recognition part; and a vehicle control part which controls the own vehicle so that the inter-vehicle distance between the own vehicle and the preceding vehicle becomes larger if the preceding vehicle pixel amount is larger than the appropriate pixel amount.SELECTED DRAWING: Figure 3

    【課題】先行車群に対する車間距離制御の演算処理量を低減することができる車間距離制御装置を提供する。【解決手段】自車両と先行車との車間距離を制御するための車間距離制御装置であって、自車両の前方カメラの撮像画像に基づいて、先行車を含む先行車群を認識する先行車認識部と、撮像画像における先行車群のピクセル量である先行車ピクセル量を算出する先行車ピクセル量算出部と、予め設定された設定車速又は現在車速と予め設定された設定車間距離と先行車認識部による先行車群の認識結果とに基づいて、撮像画像における先行車群の適正ピクセル量を算出する適正ピクセル量算出部と、先行車ピクセル量が適正ピクセル量より大きい場合に、自車両と先行車との車間距離が大きくなるように自車両を制御する車両制御部と、を備える。【選択図】図3
