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 calculates routes capable of be set for a travelling road of an evaluation determination zone and the total of the routes, and calculates, from among the calculated whole routes, the number of non-interference routes that are estimated not to interfere with other vehicles detected by an other vehicle detection unit. Then, the travelling allowance calculation device calculates a ratio of the number of the non-interference routes to the number of the whole routes as a travelling allowance representing the degree of travelling freedom of an 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、評価判定区間の走行路に設定可能な経路及びその経路の総数を算出し、算出した全経路のうち、上記他車両検出部が検出した他車両と干渉しないと推定される経路である非干渉経路の本数を算出する。そして、上記全経路の本数に対する上記非干渉経路の本数の割合を、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35
