To provide a travel storage system and travel storage method making it possible to check the reliability of latent accident liability information.SOLUTION: A travel storage system includes: an object vehicle behavior determination unit (141) that acquires, from a sensor (111), a sensor value (S) indicative of a behavior of each of surrounding vehicles existing around an own vehicle (1), and sequentially determines a relative behavior (V) of an object vehicle selected from among the surrounding vehicles, with respect to the own vehicle (1) on the basis of the sensor value (S); a rule acquisition unit (142) that acquires an accident liability rule at a present position of the own vehicle (1); a latent accident liability value determination unit (151) that sequentially determines a latent accident liability value (AL) indicative of a degree of liability of the own vehicle (1) for an accident presumed between the object vehicle and own vehicle (1), on the basis of the relative behavior (V) of the object vehicle and the accident liability rule; and a latent accident storage unit (152) that stores the latent accident liability value (AL) in association with liability value determination information (R) which is information employed in determining the latent accident liability value (AL).SELECTED DRAWING: Figure 1
【課題】潜在事故責任情報の信頼性を確認することを可能にする走行記憶システム、および走行記録方法を提供すること。【解決手段】自車両(1)の周囲に存在する周辺車両の挙動を示すセンサ(111)からセンサ値(S)を取得し、センサ値(S)に基づいて、周辺車両から選択した対象車両の自車両(1)に対する相対挙動(V)を逐次決定する対象車両挙動決定部(141)と、自車両(1)の現在位置における事故責任ルールを取得するルール取得部(142)と、対象車両の相対挙動(V)と事故責任ルールとに基づいて、対象車両と自車両(1)との間に想定される事故に対する自車両(1)の責任の程度を示す潜在事故責任値(AL)を逐次決定する潜在事故責任値決定部(151)と、潜在事故責任値(AL)と、潜在事故責任値(AL)を決定するために用いた情報である責任値決定情報(R)とを対応づけて記憶する潜在事故記憶部(152)とを備える。【選択図】図1
