Abstract

A system for controlling an air conditioner for a vehicle may include a drive only mode selector configured to select a whole air-conditioning mode or an individual air-conditioning mode, a blower motor configured to provide different volumes of air indoors in the whole air-conditioning mode or the individual air-conditioning mode, a passenger seat mode door configured to be opened by an actuator when the whole air-conditioning mode is selected, and to be closed by the actuator when the individual air-conditioning mode is selected, and a controller configured to control a speed at which the voltage of the blower motor is decreased, or to control a speed at which the voltage of the blower motor is increased.

Claims

1. A system for controlling an air conditioner for a vehicle, the system comprising:

a drive only mode selector configured to select a whole air-conditioning mode or an individual air-conditioning mode;

a blower motor configured to provide different volumes of air indoors in the whole air-conditioning mode or the individual air-conditioning mode;

a passenger seat mode door configured to be opened by an actuator when the whole air-conditioning mode is selected, and to be closed by the actuator when the individual air-conditioning mode is selected; and

a controller configured to control a speed at which the voltage of the blower motor is decreased to follow a speed at which the operating voltage of the actuator for closing the passenger seat mode door is decreased when the individual air-conditioning mode is selected by the drive only mode selector, or to control a speed at which the voltage of the blower motor is increased to follow a speed at which the operating voltage of the actuator for opening the passenger seat mode door is increased when the whole air-conditioning mode is selected by the drive only mode selector.

2. A method for controlling an air conditioner for a vehicle, the method comprising:

selecting a whole air-conditioning mode or an individual air-conditioning mode; and

when the whole air-conditioning mode or the individual air-conditioning mode is selected, controlling a speed at which the voltage of the blower motor for providing the volume of air is changed to a speed at which the operating voltage of the actuator for opening/closing the passenger seat mode door is changed.

3. The method of claim 2, wherein, when the individual air-conditioning mode is selected, the speed at which the voltage of the blower motor for providing the volume of air is decreased is controlled to follow the speed at which the operating voltage of the actuator for closing the passenger seat mode door is decreased.

4. The method of claim 2, wherein, when the whole air-conditioning mode is selected, the speed at which the voltage of the blower motor for providing the volume of air is increased is controlled to follow the speed at which the operating voltage of the actuator for opening the passenger seat mode door is increased.

5. The method of claim 2, wherein the change in voltage of the blower motor is controlled based on an equation of √

{square root over (α

V_m)}=ν

_c(2A₀−

A_d sin θ

)=ν

_c(2A₀−

A_d sin β

V_a) which is a relationship between operating voltages of the actuator and voltages of the blower motor.

6. The method of claim 3, wherein the change in voltage of the blower motor is controlled based on an equation of √

{square root over (α

V_m)}=ν

_c(2A₀−

A_d sin θ

)=ν

_c(2A₀−

A_d sin β

V_a) which is a relationship between operating voltages of the actuator and voltages of the blower motor.

7. The method of claim 4, wherein the change in voltage of the blower motor is controlled based on an equation of √

{square root over (α

V_m)}=ν

_c(2A₀−

A_d sin θ

)=ν

_c(2A₀−

A_d sin β
