PROBLEM TO BE SOLVED: To provide an autonomous driving vehicle system that reduces annoyance to be perceived by a driver when the driver of a vehicle in an autonomous driving state tentatively intervenes in driving.SOLUTION: A system includes an acquisition unit that acquires a manipulation quantity of a driver's driving manipulation or a continuity count dependent on a duration of a driving manipulation, and a switching unit that switches an autonomous driving state, collaborative driving state, and manual driving state according to the manipulation quantity or continuity count. When the autonomous driving state is established, if the manipulation quantity becomes equal to or larger than an intervention threshold and falls below an initiation threshold or when the continuity count becomes equal to or larger than a first threshold and falls below a second threshold, the switching unit switches the autonomous driving state to the collaborative driving state. When the collaborative driving state is established, if the manipulation quantity falls below the intervention threshold or the continuity count falls below the first threshold, the switching unit switches the collaborative driving state to the autonomous driving state. When the manipulation quantity becomes equal to or larger than the initiation threshold or the continuity count becomes equal to or larger than the second threshold, the switching unit switches the collaborative driving state to the manual driving state.SELECTED DRAWING: Figure 1
【課題】自動運転状態の車両に運転者が一時的に介入する場合に運転者に煩わしさを感じさせることを低減する自動運転車両システムを提供する。【解決手段】システムは、運転者の運転操作の操作量又は運転操作の継続時間に応じた継続カウントを取得する取得部と、自動運転状態、協調運転状態及び手動運転状態を、操作量又は継続カウントに基づいて切り換える切換部と、を備え、切換部は、自動運転状態中に、操作量が介入閾値以上かつ開始閾値未満になったとき、又は継続カウントが第1閾値以上かつ第2閾値未満になったときには、協調運転状態に切り換え、協調運転状態中に、操作量が介入閾値未満になったとき、又は継続カウントが第1閾値未満になったときには、自動運転状態に切り換え、操作量が開始閾値以上になったとき、又は継続カウントが第2閾値以上になったときには、手動運転状態に切り換える。【選択図】図1
