Abstract
A vehicle air conditioner has a standby RAM having a map memorizing many regions of, for example, preset temperature, each of which is determined by environmental conditions such as the inside/outside air temperatures and the sunlight amount. The air conditioner automatically controls the air conditioning of the passenger compartment of the vehicle based on the information stored in the region of the map determined by the environmental conditions that is regarded as a control preset temperature used for calculating a target blowing temperature in a control flow repeating cyclically. When the preset temperatures read at the previous cycle and the current cycle are different from each other, the control preset temperature is regarded as the preset temperature which changes gradually from the previous one to the current one, whereby the temperature of air blown into the passenger compartment gradually changes.
