PROBLEM TO BE SOLVED: To more appropriately grasp the degree of travelling 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 estimates, after detecting an escape vehicle, one of the number of vehicles whose speeds are reduced by the escape vehicle and the amount of the reduced speeds, and, based on the one of the estimated number of the vehicle whose speeds are reduced and the estimated amount of the reduced speeds, calculates a travelling allowance representing the degree of travelling freedom of an own vehicle for other vehicles. At this time, the degree of the travelling freedom is calculated to become smaller as the number of other vehicles whose speeds are reduced increases or the amount of the reduced speeds increases.
【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、避走車両を検出すると、上記避走車両により減速する車両の台数及びその減速量の一方を推定し、推定した減速する車両の台数及びその減速量の一方から、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を算出する。このとき、減速する他車両の台数が多いほど、又は減速量が大きいほど、上記走行余裕度を小さく算出する。【選択図】 図37
