Zusammenfassung:	A SBW-ECU includes: a P unreleasable region determination portion configured to determine whether a road surface slope Sr at a vehicle position and an output voltage Volr of an auxiliary battery fall within a predetermined parking lock unreleasable region or not; and a P release request rejection portion configured to reject a P release request in a case where P release request rejection conditions to are all satisfied, including a fact that the P unreleasable region determination portion determines that the road surface slope Sr at the vehicle position and the output voltage Volr of the auxiliary battery fall within the parking lock unreleasable region (the P release request rejection condition (c) is satisfied).
