To provide a precedent vehicle selecting device that selects a precedent vehicle to be followed so that effect of improvements in fuel economy or electricity consumption made by following travelling is increased, in consideration of a preference of an occupant in a vehicle.SOLUTION: A precedent vehicle selecting device comprises: a peripheral information obtaining part 15 that obtains information concerning surrounding vehicles 30 around an own vehicle 20; a parameter calculating part 16 that calculates relative speeds between the own vehicle and the surrounding vehicle, degrees of air resistance reduced by travelling while following the surrounding vehicle and vehicle speed stability of the surrounding vehicle, on the basis of the information concerning the surrounding vehicle, with respect to each of the surrounding vehicles; and a precedent vehicle selecting part 17 that selects a precedent vehicle out of the surrounding vehicles. The precedent vehicle selecting part selects the precedent vehicle on the basis of the relative speeds, the degrees of air resistance reduced, the vehicle speed stability, and preference information preset by an occupant in the own vehicle concerning selection of the precedent vehicle.SELECTED DRAWING: Figure 4
【課題】車両の乗員の嗜好を考慮しつつ、追従走行による燃費又は電費の改善効果が高くなるように追従対象の先行車を選定する。【解決手段】先行車選定装置は、自車両20の周囲の周辺車両30に関する情報を取得する周辺情報取得部15と、周辺車両のそれぞれについて、周辺車両に関する情報に基づいて、自車両と周辺車両との相対速度と、周辺車両への追従走行による空気抵抗低減度と、周辺車両の車速安定度とを算出するパラメータ算出部16と、周辺車両の中から先行車を選択する先行車選択部17とを備える。先行車選択部は、相対速度と、空気抵抗低減度と、車速安定度と、先行車の選定に関して自車両の乗員によって予め設定された嗜好情報とに基づいて先行車を選択する。【選択図】図4
