PROBLEM TO BE SOLVED: To provide a vehicle autonomous drive controller and a vehicle autonomous drive control method capable of increasing the frequency of stopping an internal combustion engine during a vehicle autonomous drive control to reduce fuel consumption, and improving fuel economy.SOLUTION: A vehicle autonomous drive controller is configured to exert a control to change driving of a vehicle 1 to coasting driving D2 in a front interval Lx if it is determined that a gradient θy of a downhill road Ly is equal to a gravity acceleration gradient θa, and to exert a control to change the driving of the vehicle 1 to acceleration-deceleration driving D3 on the downhill road Ly if it is determined that the gradient θy of the downhill road Ly is equal to the gravity acceleration gradient θa and when it is determined that the gradient θy of the downhill road Ly is equal to a fuel economy degrading gradient θb.SELECTED DRAWING: Figure 4
