Abstract
An ECU computes a guard value K and limits an amount of change in a measured atmospheric pressure value of an atmospheric pressure sensor per unit time through use of the computed guard value. The guard value is a value that corresponds to an amount of change in the atmospheric pressure per unit time caused by a change in an altitude.
