Abstract
This invention has as its object to provide a method and apparatus for controlling a vehicle air conditioner, which can obtain a combination of an outlet air flow rate V.sub.a and an outlet air temperature T.sub.o, which is desirable for comfort of a passenger, under a condition of air-conditioning control based on a heat balance equation. In order to achieve this object, this invention provides a method of controlling a vehicle air conditioner, including the first step of obtaining, from a heat balance equation, a plurality of combinations of the outlet air flow rates V.sub.a and the outlet air temperatures T.sub.o necessary for maintaining the passenger room temperature to be a predetermined target temperature, the second step of calculating comfort indices each representing the comfort level of a passenger on the basis of state amounts of factors which influence comfort felt by the passenger in the passenger room, and the plurality of combinations of the outlet air flow rates V.sub.a and the outlet air temperatures T.sub.o obtained in the first step, and the third step of searching a combination of the outlet air flow rate and the outlet air temperature, which can provide a comf…
