Hereinafter, with reference to the accompanying drawings, preferred embodiments of the vehicle air conditioner according to the present invention will be described in detail.

First, prior to looking at the features of the vehicle air conditioner according to the present invention, with reference to Figure 1 will be briefly described for the air conditioning apparatus of the automatic control method.

The air conditioning apparatus of the automatic control method includes a plurality of detection sensors 1 for detecting interior and exterior conditions. For example, an internal sensor for detecting the temperature inside the vehicle, an outdoor sensor for sensing the temperature outside the vehicle, a humidity sensor for detecting the humidity in the vehicle, a solar sensor for detecting the solar load, and the like.

And the air conditioning apparatus of the automatic control system is provided with the control part 3. As shown in FIG.

The controller 3 includes a microprocessor and various driving circuits. The controller 3 processes data input from the detection sensors 1 that detect conditions inside and outside the vehicle, and according to the processed result, the air conditioner 5 and the heater. (7), PTC auxiliary heater 9, various doors 11, blowers 13 and the like are controlled.

Therefore, according to the conditions inside and outside the vehicle, the temperature and the amount of air and the wind speed of the vehicle are automatically controlled. As a result, the temperature in the vehicle interior is always kept comfortable.

In addition, the controller 3 may control the display unit 15 according to the current control state of the air conditioning apparatus. Accordingly, various display symbols of the display unit 15 can display the current control state of the air conditioning apparatus.

In addition, the control unit 3 is configured to store the control state of the air conditioning apparatus before the start is turned off, for example, the air discharge mode, the air volume, whether the air conditioner and the heater are operated when the vehicle is turned off. do.

When the vehicle is restarted, the air conditioner 5, the heater 9, the PTC auxiliary heater 9, the various doors 11, the blower 13, and the like are controlled so as to reproduce the control state of the air conditioner previously stored. do. Therefore, the condition in the vehicle interior is restored to the state before the start-up was turned off.

Next, the features of the vehicle air conditioner according to the present invention will be described in detail with reference to FIG.

First, the air conditioner of the present invention includes a start detecting means 20 for detecting whether the starting of the vehicle is ON.

The start detecting means 20 is configured as a start switch of the vehicle and detects the start of the vehicle and outputs a "start signal" S1. In particular, it outputs to the control part 3.

The air conditioner according to the present invention includes air conditioner operating condition discrimination means (30) for determining whether the interior and exterior of the air conditioner is a condition in which the air conditioner (5) does not need to be operated.

Air conditioner operating condition determination means 30, the auxiliary heater detection means 32 for detecting the operation of the PTC auxiliary heater 9 and the air conditioner 5 does not need to operate in accordance with the signal of the auxiliary heater detection means 32 And a determining section 34 for determining whether or not a condition is present.

The auxiliary heater detecting means 32 is composed of a voltage sensor that senses the voltage applied to the PTC auxiliary heater 9, the voltage sensor thus configured detects the voltage applied to the PTC auxiliary heater 9, and then " The heater operation signal "S2 is input to the discriminating part 34.

When the "secondary heater operation signal" (S2) is input from the auxiliary heater detection means 32, the determination unit 34 has a low temperature in the interior of the vehicle so that the current PTC auxiliary heater 9 operates so that the air conditioner 5 A condition that does not need to be operated is determined, and according to this determination, an "air conditioner non-operation condition signal" S3 is output. In particular, it outputs to the control part 3.

Referring back to FIG. 1, the air conditioner of the present invention includes a control unit 3, wherein the control unit 3 receives a "start signal" S1 from the start detection unit 20, and operates the air conditioner. When the " air conditioner non-operation condition signal " S3 is input from the condition determination means 30, the air conditioner 5 can be operated unnecessarily at the time of restarting the vehicle, even though it is a condition in which the air conditioner 5 is not currently operated. I think there is concern.

In response to this determination, the air conditioner 5 is forcibly turned off by outputting an "air conditioner off signal" S4. In particular, the air conditioner 5 is unconditionally turned off even when the air conditioner 5 is ON controlled before the vehicle startup is turned off.

Therefore, when restarting the vehicle, it is possible to prevent the air conditioner 5 from being operated unnecessarily even though the air conditioner 5 is not an operating condition. As a result, it is possible to prevent the fuel economy of the vehicle caused by unnecessary operation of the air conditioner (5).

On the other hand, when the "air conditioner non-operation condition signal" S3 of the air conditioner operation condition determination means 30 is erased, the control unit 3 erases the "air conditioner off signal" S4. And the air conditioner (5) is automatically adjusted according to the conditions inside and outside the vehicle.

On the other hand, the control part 3 memorize | stores the state of the air conditioner 5 which turned off, when the vehicle start-up turns off in the state which forcibly turned off the said air conditioner 5. Therefore, the air conditioner 5 is controlled to the off state at the restart of a vehicle.

Next, an operation example of the air conditioner having such a configuration will be described with reference to FIGS. 1 and 2.

First, in a state in which the vehicle is started (S101), it is determined whether the condition that the air conditioner 5 does not need to be operated (S103). The judgment at this time is determined by detecting the operation of the PTC auxiliary heater (9).

As a result of the determination, if the condition that the air conditioner 5 does not need to be operated, the air conditioner 5 is forcibly turned off (S105).

Therefore, when the vehicle is restarted, the air conditioner 5 is prevented from being operated unnecessarily even though the air conditioner 5 is not an operating condition. As a result, it is possible to prevent the fuel economy of the vehicle caused by unnecessary operation of the air conditioner (5).

On the other hand, when the determination result is not a condition in which the air conditioner 5 does not need to be operated (S103-1), that is, a condition in which the air conditioner 5 should be operated, the air conditioner 5 is stored in the control unit 3. It is automatically controlled according to the control state (S107). In particular, if the air conditioner 5 is turned on before the vehicle startup is turned off, the air conditioner 5 is restarted while the vehicle is restarted.

Referring again to FIG. 2, in a state in which the air conditioner 5 is forcibly turned off (S105) or in a state in which the air conditioner 5 is automatically controlled (S107), when the vehicle is turned off (S109), the controller 3 Stores the current control state of the air conditioner 5 (S111). Therefore, the air conditioner 5 is controlled according to the data memorize | stored in advance at the vehicle restart.

Next, Figure 3 is a view showing a modification of the air conditioner operating condition determination means 30 constituting the air conditioning apparatus of the present invention.

The air conditioner operating condition determining means 30 of the modified example is characterized in that the air conditioner 5 does not operate according to the air temperature sensing means 36 for detecting the temperature in the vehicle interior and the air temperature input from the air temperature sensing means 36. And a judging section 38 for judging whether or not it is a condition.

The internal temperature sensing means 36 detects the temperature in the vehicle interior and outputs the temperature to the determination unit 38.

The discriminating unit 38 compares a factor within the vehicle interior inputted from the indoor temperature detecting means 36 with a factor equal to or less than a preset "reference temperature".

As a result of the comparison, if the temperature in the vehicle interior input from the internal temperature sensing means 36 is less than or equal to the “reference temperature”, the temperature is determined to be a condition in which the temperature in the vehicle interior is low and the air conditioner 5 does not need to be operated. The " air conditioner non-operation condition signal " (S3) is output.

The air conditioner operating condition determining means 30 of this modification is a structure that determines the condition in which the air conditioner 5 does not need to operate based on the temperature in the vehicle cabin, and thus determines the condition in which the air conditioner 5 does not need to operate in more detail. can do.

Therefore, even if the air conditioner 5 is not an operating condition, the air conditioner 5 can be prevented from operating unnecessarily. As a result, it is possible to more effectively prevent the fuel economy of the vehicle caused by unnecessary operation of the air conditioner (5).

On the other hand, the " reference temperature " incorporated in the discriminating unit 38 is preferably about 20 deg. This is because, when the temperature in the vehicle interior is about 20 ° C., the interior of the vehicle is kept comfortable even if the air conditioner 5 is not operated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
