PURPOSE:To properly change the functional elements of a car air conditioner by actuating a visible indicator through its functional status change detection and annunciating the functional status change contents through a sound based on the reaction of a driver. CONSTITUTION:Room temperature 8, the degree of opening of a core mix damper 6, outer temperature 10, and gas concentration 11 are input to an initialized microcomputer 17 through an A/D converter 16 and the high speed load information 12 of a vehicle, preset temperature 13, and the outer air signal 15 of inner and outer air selection dampers 2 are input to it. The outer air selection conditions of the inner and outer selection damper 2 and the selection conditions of a compressor on/off switch 14 are decided and displayed on an indicator 20 when they must be changed. When a driver caecks the display and turning on a sound switch 21, the required sound stored in a sound synthesizer 22 is annuciated by th command of the microcomputer 17. As a result, status can properly be changed. |
