PROBLEM TO BE SOLVED: To more appropriately grasp the degree of traveling freedom of an own vehicle for other vehicles, such as the degree of allowance of lane changes of the own vehicle.SOLUTION: A travelling allowance calculation device for a vehicle sets a whole area of the road surface of an evaluation determination zone as a virtual visible area on the basis of information of a travelling road, and calculates an actual visible area that is obtained by removing a blind area invisible from an own vehicle due to other vehicles from the virtual visible area. Then, the travelling allowance calculation device calculates a ratio of the actual visible area to the virtual visible area as a travelling allowance representing the degree of travelling freedom of the own vehicle for other vehicles.

    【課題】自車両の車線変更の余裕度など、他車両に対する自車両の走行自由度の度合を、より適切に把握可能とする。【解決手段】車両の走行余裕度算出装置は、上記走行路の情報から上記評価判定区間の路面の全領域を仮想の見通し可能領域として設定する。また、仮想の見通し可能領域から他車両によって自車両から死角となる死角領域を除いた領域である、実際の見通し可能領域を算出する。そして、仮想の見通し可能領域に対する上記実際の見通し可能領域の割合を、他車両に対する自車両の走行自由度の度合を表す走行余裕度として算出する。【選択図】 図38
