The parking control method includes detecting a relative altitude between a first height position of the operator and a second height position of the vehicle and when determining that the relative altitude is not less than a first predetermined value, changing a first speed to a second speed lower than the first speed. The first speed is preliminarily set in the control instruction. The parking control method further includes moving the vehicle in accordance with the control instruction changed.
