To show an optimum travel route taking into account the driving load of a driver during traveling.SOLUTION: When the cumulative value of driving loads exceeds a first threshold Th1, the cumulative value of driving loads to a destination M is estimated, taking into account the remaining distance to the destination M and the road condition of a travel route, and a travel route where this driving load estimated value F does not exceed a second threshold Th2 is presented, thereby the driver can reach the destination M at ease. The driving load estimated value F is estimated from the remaining travel distance from a point where the cumulative value exceeded the first threshold Th1 to the destination M, the estimated number of times sudden braking will be performed in the remaining travel route, and an external environment. The number of times sudden braking will be performed is estimated, from the remaining travel route to the destination M, by counting the number of scenes identical or similar to a scene where sudden braking is performed before the cumulative value of driving loads exceeds the first threshold Th1.SELECTED DRAWING: Figure 5
【課題】運転者の走行中における運転負荷を考慮した最適な走行ルートを案内する。【解決手段】運転負荷の累積値が第1閾値Th1を越えた場合、目的地Mまでの残り距離や、走行ルートの道路状況を考慮して、目的地Mまでの運転負荷の累積値を予想し、この運転負荷予想値Fが第2閾値Th2を越えない走行ルートを案内することで、運転者が安心して目的地Mにたどり着けるようにする。運転負荷予想値Fは、累積値が第1閾値Th1を越えた地点から目的地Mまでの、残りの走行距離と、残りの走行ルートで予想される急制動操作の回数、及び、外部環境から予想する。急制動操作の回数は、運転負荷の累積値が第1閾値Th1を越えるまでの間に、急制動が行われた状況(シーン)と同一又は類似した状況の数を、目的地Mまでの残りの走行ルートから予想する。【選択図】図5
