PROBLEM TO BE SOLVED: To provide a technique capable of improving the accuracy in inclination calculation of a downhill road.SOLUTION: The road inclination acquisition system includes: an up-hill road inclination acquisition part that acquires an inclination of an up-hill road based on the behavior of a vehicle in the up-hill road; an adjacent determination section that determines whether the opposite lane is adjacent to the traffic lane on which the vehicle is travelling in the up-hill road; and a downhill road inclination acquisition part that, when the opposite lane is adjacent thereto, acquires the inclination of the downhill road including the opposite lane based on the inclination of the up-hill road.SELECTED DRAWING: Figure 1
