ROAD-SURFACE INCLINED-STATE DETECTION METHOD AND VEHICLE CONTROL METHOD

A road-surface inclined-state detection method, applicable to a vehicle control method, includes an acquisition step of acquiring a vehicle state where pitching moment causing front wheels 32 of a vehicle 1 to move upward in a vertical direction relative to rear wheels 42 of the vehicle 1 is applied to the vehicle 1, and where rear suspensions 40 suspending the rear wheels 42 are stroked in a compressing direction, a count step of starting counting after the vehicle state acquired in the acquisition step meets a predetermined condition, and continuing the counting until the vehicle state fails to meet the predetermined condition, and an inclined-state detection step of detecting an inclined state of a road surface R on which the vehicle 1 travels, according to count values counted in the count step.
