To recognize in which of an automatic driving mode and a manual driving mode a vehicle traveling ahead travels.SOLUTION: A travel mode recognition device 200 comprises: an inter-vehicle distance detection part 51 which detects a travel state of a vehicle traveling ahead; a variance calculation part 61 which calculates an extent of variance in vehicle speed or acceleration of the vehicle traveling ahead based upon the travel state detected by the inter-vehicle distance detection part 51; and a travel mode determination part 62 which determines in which of an automatic driving mode and a manual driving mode the vehicle traveling ahead travels based upon the extent of variance calculated by the variance calculation part 61.SELECTED DRAWING: Figure 12
【課題】前方車両が自動運転モードおよび手動運転モードのいずれで走行しているかを認識する。【解決手段】走行態様認識装置200は、前方車両の走行状態を検出する車間距離検出部51と、車間距離検出部51により検出された走行状態に基づき、前方車両の車速または加速度のばらつきの程度を算出するばらつき算出部61と、ばらつき算出部61により算出されたばらつきの程度に基づいて、前方車両が自動運転モードと手動運転モードのいずれで走行しているかを判定する走行モード判定部62と、を備える。【選択図】図12
