To smooth switching in the case of needing switching from a first state in which driving control is automatically executed to a second state in which the degree of participation in driving control by a driver is larger than in the first state, and to inhibit the comfort of automatic driving from being damaged due to the prediction of a situation in which uncertain automatic driving cannot be continued.SOLUTION: In the case that an event having the possibility that automatic driving ahead of the route of an own vehicle cannot be continued is detected (S12), the degree of an encounter, the degree of emergency, importance, or the like to the event is considered to calculate an alarm level (S16), the form of information presentation and the strength of stimulation are automatically determined in accordance with the alarm level, and information is presented with sufficient time before coming close to an occurrence point of the event (S18). In the case that the degree of an encounter, the degree of emergency or the importance is low, the comfort of automatic driving can be maintained by presenting the information at the minimum awareness level.SELECTED DRAWING: Figure 2
【課題】運転制御が自動で実行される第1状態から、第1状態よりも運転者による運転制御に対する関与の度合いが大きい第2状態への切替が必要な場合の切替を円滑にすると共に、不確定の自動運転が継続できなくなる状況の予測に伴って自動運転の快適性が損なわれるのを抑制すること。【解決手段】自車両の進路前方における自動運転が継続できなくなる可能性がある事象を検知した場合に(S12)、当該事象に対する遭遇度、緊急度又は重要度などを考慮して警報レベルを算出し(S16)、警報レベルに応じて、情報提示の形態と刺激の強さを自動的に決定し、当該事象の発生地点に接近する前に、余裕を持って情報を提示する(S18)。遭遇度、緊急度又は重要度が低い場合には、最低限の気づきレベルで情報を提示することにより、自動運転の快適性を維持できる。【選択図】図2
