KR-102961327-B1 - AIR CONDITIONING SYSTEM FOR AUTOMOTIVE VEHICLES

Abstract

The present invention relates to a vehicle air conditioning system, and aims to prevent user confusion and misunderstanding caused by the air conditioning switch being activated even though the air conditioning system is not actually operating in the ACC power mode by restricting the activation of the air conditioning switch in the ACC power mode in a controller of the air conditioning system equipped with an air conditioning switch for controlling the air conditioning system and an AVN switch for controlling the AVN system (Audio Video Navigation System). To achieve this objective, the present invention provides a vehicle air conditioning system comprising a controller having a plurality of air conditioning switches capable of controlling an air conditioning system and a plurality of AVN switches capable of controlling an AVN system (Audio Video Navigation System), wherein the controller controls whether the air conditioning switches and AVN switches of the controller are activated according to the power supply status of the vehicle before and after starting, and determines whether the air conditioning switches and AVN switches are operated according to the power supply status of the vehicle.

Description

Air Conditioning System for Automotive Vehicles The present invention relates to a vehicle air conditioning system, and more specifically, to a vehicle air conditioning system that prevents user confusion and misunderstanding caused by the activation of the air conditioning switch even though the air conditioning system is not actually operating in the ACC power mode, by restricting the activation of the air conditioning switch in the ACC power mode in a controller of the air conditioning system equipped with an air conditioning switch for controlling the air conditioning system and an AVN switch for controlling an AVN system (Audio Video Navigation System). A vehicle air conditioning system is equipped with a controller for controlling the device. The controller is typically installed on the center fascia panel in front of the driver's seat and, as shown in FIGS. 1 and 2, includes a housing (10), a plurality of switches (20) and a display unit (30) installed in the housing (10). The controller of such an air conditioning system is increasingly being integrated with an AVN system (Audio Video Navigation System) in recent years, and in accordance with this trend, it is equipped with air conditioning switches (22) capable of controlling the air conditioning system and AVN switches (24) capable of controlling the AVN system. Meanwhile, the air conditioning switches (22) and AVN switches (24) are touch-type and are configured to share one switch for each control item (hereinafter, the shared switches of the air conditioning switches (22) and AVN switches (24) are referred to as "air conditioning and AVN shared switches (20)"). In particular, the air conditioning and AVN common switches (20) are alternately switched between an air conditioning mode and an AVN mode as shown in FIGS. 1 and FIGS. 2, depending on the number of times a mode switching switch (26) installed on one side of the controller is pressed. The air conditioning and AVN common switches (20) that are switched in this way are activated as an air conditioning switch (22) or an AVN switch (24) in accordance with the switched mode, and output a signal according to the user's operation to control the air conditioning device or AVN system. Here, an air conditioning symbol (22a) corresponding to the air conditioning switch (22) and an AVN symbol (24a) corresponding to the AVN switch (24) are each separately formed in the surrounding area of the air conditioning and AVN common switches (20). The above air conditioning symbols (22a) and AVN symbols (24a) are selectively illuminated when switching between air conditioning mode and AVN mode according to the operation of the mode switching switch (26), thereby notifying the user of the selection of the corresponding mode. However, this conventional air conditioning system has the disadvantage that the air conditioning mode is selected through the mode switching switch (26) of the controller in the ACC (Accessory) power mode, where power is supplied only to the electronic equipment of the vehicle, for example, in the ACC power mode before IGN2, or in the ACC delay (Accessory Delay) power mode, where the ACC power is maintained for a certain period of time after the ignition is turned off. Due to this disadvantage, there is a problem that the air conditioning switch (22) is activated in the ACC mode. In particular, there is a problem that the air conditioning switch (22) is activated even though the vehicle is not started and the air conditioning system is not operating, and due to this problem, there is a drawback that it may give the user an unnecessary misunderstanding that the air conditioning system can operate even though the air conditioning system is not operating in ACC mode. FIG. 1 is a drawing showing a controller of a conventional vehicle air conditioning system, showing the air conditioning and AVN common switches activated as air conditioning switches when entering the air conditioning mode. FIG. 2 is a drawing showing a controller of a conventional vehicle air conditioning system, showing the air conditioning and AVN common switches activated as AVN switches when entering AVN mode. FIG. 3 is a drawing showing the configuration of a vehicle air conditioning system according to the present invention. FIG. 4 is a flowchart showing an example of operation of a vehicle air conditioning system according to the present invention. Hereinafter, a preferred embodiment of a vehicle air conditioning system according to the present invention will be described in detail with reference to the attached drawings (components identical to those of the prior art are described using the same reference numerals). First, before examining the features of the vehicle air conditioning system according to the present invention, the controller of the vehicle air conditioning system will be briefly described with reference to FIGS. 1 and FIGS. 2. A controller for a vehicle air conditioning system includes a housing (10), a
