PROBLEM TO BE SOLVED: To provide a drive support device capable of performing drive support in a manner that avoids a situation with a high drive load.SOLUTION: A drive support device comprises: overt proximity degree calculation means 150 which calculates a degree of proximity between an own vehicle and a mobile object, as an overt degree of proximity, on the basis of own vehicle information on a travel state of the own vehicle and mobile object information on a moving state of the mobile object under the assumption that a current travel state of the own vehicle and a current moving state of the mobile object are maintained; latent proximity degree calculation means 150 which calculates the degree of proximity between the own vehicle and the mobile object in a virtual state where a relation between the current travel state of the own vehicle and the current moving state of the mobile object is changed; and drive support means 150 which performs first drive support or second drive support after determining whether the first drive support according to the overt degree of proximity or the second drive support according to the latent degree of proximity needs to be performed on the basis of the overt degree of proximity and the latent degree of proximity. 【課題】運転負荷の高い状況が回避されるように運転支援を行うことが可能な運転支援装置を提供する。【解決手段】自車両の走行状態に関する自車両情報および移動体の移動状態に関する移動体情報に基づいて、自車両の現在の走行状態および移動体の現在の移動状態が継続された場合に自車両と移動体とが接近する度合いを、顕在的接近度合として算出する顕在的接近度合算出手段１５０と、自車両の現在の走行状態と移動体の現在の移動状態との関係を変化させた仮想状態において自車両と移動体とが接近する度合いを潜在的接近度合として算出する潜在的接近度合算出手段１５０と、顕在的接近度合と潜在的接近度合とに基づいて、顕在的接近度合に応じた第１の運転支援、および、潜在的接近度合に応じた第２の運転支援のいずれを行うかを判断し、第１の運転支援または第２の運転支援を行う運転支援手段１５０と、を備えることを特徴とする運転支援装置。【選択図】図１
