supply air to the air cell if the difference between the first and second internal pressures is greater than a threshold value, and
vary a next time after the second time at which to acquire the internal pressure of the air cell based on whether the difference between the first and second internal pressures is greater than the threshold value or not, a first time interval from the second time to the next time when the difference is greater than the threshold value being less than a second time interval from the second time to the next time when the difference is not greater than the threshold value.
