BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control method of an air conditioner system for a vehicle. In particular, in an air conditioner system according to a manual type driving method, an air intake mode, that is, an intake mode, in a recircle mode when an air conditioner is operated, The present invention relates to a control method of a vehicle air conditioner system which can guarantee the air conditioner performance by forcibly switching to the

In general, the vehicle is equipped with an air conditioning system for the convenience of the driver and the passenger, and as shown in Figure 1 consists of an indoor temperature sensor, outside temperature sensor, solar radiation sensor, evaporator temperature sensor, etc. A sensor panel 11 providing various necessary information, a control panel unit 12 including keys and control switches for selecting air-conditioning, room temperature, wind direction, air volume, air intake mode, and the like, and the sensor unit (11) and MICOM (13) for outputting various control and drive signals in accordance with the input of the control panel unit 12, and the intake door for each internal / outdoor mode in accordance with the control and drive signals of the microcomputer (13) Actuator to operate the actuator, Actuator to operate the Air Mix Door for each cooling and heating mode, Actuator to operate the mode door for each vent, etc. The actuator part 14, the blower motor 15 which operates a blower fan, the evaporator 16 which cools air, and the heater 17 which heats air are comprised.

The air conditioner system configured as described above is a manual type air conditioner system in which a driver arbitrarily selects and uses an air conditioner mode and a fully automatic temperature that detects the temperature of a vehicle interior and automatically adjusts it to an optimal condition by comparing with a set temperature. It is divided into air conditioner system of full automatic temperature controller (hereinafter referred to as 'FATC') type.

In particular, the FATC is a device for automatically adjusting the air flow direction, the air flow rate, the room temperature and the outside air temperature to maintain a comfortable interior space regardless of the external conditions, the price is quite expensive and is applied only to luxury vehicles have.

Nowadays, a lot of users who are reluctant to choose a FATC type driving method that cannot be arbitrarily selected in the air conditioner system, that is, consumers, have been increasing, and a tendency to prefer a low price manual type driving method is increasing.

That is, the air conditioner system according to the manual type driving method may be preferred to the air conditioner system according to the FATC type driving method due to the advantage that the user can arbitrarily operate the air conditioner according to the corresponding function and the price is low.

On the other hand, in the conventional use of the air conditioner system according to the manual type of driving method as described above, many users may be in the air intake mode, that is, intake mode when operating the air conditioner due to lack of understanding and understanding of the use of the air conditioner system Many people complained about poor air conditioner performance without realizing that they had to switch to mode.

The present invention is to solve the above problems, the purpose of the manual type drive system in the air conditioning system, by operating the blower motor while operating the air conditioner by switching the intake mode to bet mode manual In the case of an air conditioning system according to the driving method of the type, it is to provide a control method of the vehicle air conditioning system that can guarantee the air conditioner performance while eliminating the need to switch the intake mode to the bet mode. .

Control method of a vehicle air conditioner system of the present invention for achieving the above object, comprising a sensor unit, a control panel unit, a microcomputer, an actuator unit, a blower motor, an evaporator, a heater to provide a comfortable vehicle indoor environment In the control method of the system, the microcomputer is the air conditioner is operated while the blower motor is operated, the temperature set by the temperature control switch in the control panel unit is the vehicle interior cooling, the discharge port set by the mode selection switch in the control panel unit In the case of air-conditioning VENT or VENT / FOOT or FOOT, the intake mode is controlled to be forced to bet mode.

Hereinafter, with reference to the accompanying drawings will be described in detail a control method of a vehicle air conditioner system according to the present invention.

The control method of the vehicle air conditioner system according to the present invention is performed in the vehicle air conditioner system configured as shown in FIG.

The control method of the vehicle air conditioner system according to the present invention will be described with reference to the block diagram of the vehicle air conditioner system shown in FIG. 1 and the operation flowchart of FIG. 2.

First, the microcomputer 13 of the vehicle air conditioner system determines whether the blower motor 15 is operating (S1).

As a result of the determination in step S1, if the blower motor 15 is operating, it is determined whether the air conditioner is also operating (S2). In other words, it is determined whether the evaporator 16 is operating.

Subsequently, as a result of the determination of step S2, if the air conditioner is also operating, it is determined whether the temperature set by the temperature control switch in the control panel unit 12, that is, the temperature of the vehicle interior cooling (S3).

As a result of the determination in step S3, if the temperature setting of the vehicle interior is cooling, it is determined whether the position set by the mode selection switch in the control panel unit 12, that is, the discharge port is VENT or VENT / FOOT or FOOT for cooling and heating (S4). ).

As a result of the determination in step S4, if the discharge port set by the mode selection switch in the control panel unit 12 is VENT or VENT / FOOT or FOOT for heating and cooling, the microcomputer 13 forces the intake mode to bet mode. To control.

That is, the control door and the drive signal are output to the intake door actuator in the actuator unit 14 to operate the intake door so that the vehicle interior air is circulated therein.

When the air conditioner is operated as described above, the user takes the air conditioner system according to the manual type driving method, that is, the driver, by forcing the intake mode to bet mode through the control of the microcomputer 13 to maximize the performance of the air conditioner without any additional operation. You can use it.

As described above, in the air conditioner system according to the manual type driving method, the blower motor is operated, the air conditioner is operated, the vehicle indoor temperature setting is cooling and the intake through the control of the microcomputer when the air-conditioning outlet is selected. By forcibly switching the mode to bet mode, even in the case of an air conditioner system according to the manual type driving method, it is possible to ensure the air conditioner performance while eliminating the inconvenience and inconvenience that the user must manually switch the intake mode to the bet mode. It is effective to be.
