Abstract

A proportion of outside air to recirculated air is reduced when a sensed humidity in a vehicle compartment (14) drops below a first predetermined value. If the humidity is still below the first predetermined value after a certain amount of time has elapsed, a humidifier (24) is turned on. Conversely, if the humidity rises above a second predetermined value which is higher than the first predetermined value, the humidifier (24) is turned off. If the humidity is still above the second predetermined value after a certain length of time has elapsed, the proportion of outside air to recirculated air is increased.
