Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle air conditioner that performs air conditioning control based on a temperature in a passenger compartment detected by a non-contact temperature sensor.
[0002]
[Prior art]
Conventionally, in this type of vehicle air conditioner, an occupant and the surface temperature of the background are detected by an infrared temperature sensor in which a large number of temperature detection elements are arranged in a matrix, and air conditioning control is performed based on the output signal. I am doing so. However, when a high-temperature object such as tobacco or a cold object such as can juice enters the temperature detection area, the sensor output fluctuates due to the influence of disturbances such as tobacco, resulting in unstable air conditioning control. Will occur.
[0003]
Therefore, in the vehicle air conditioner described in Japanese Patent Application Laid-Open No. 2001-334919, when a high-temperature or low-temperature region moves in a large number of temperature detection regions as time passes, it is determined that a disturbance is present. I try to eliminate the impact.
[0004]
[Problems to be solved by the invention]
By the way, since a passenger | crew's skin temperature has a correlation with a passenger | crew's thermal sensation, a passenger | crew's skin temperature is made into the important parameter | index of air-conditioning control. Therefore, it is necessary to determine in which region of many temperature detection regions the occupant's hand or face is located.
[0005]
However, the sensor output fluctuates not only due to disturbances but also due to movement of the occupant's body (particularly hands and face). However, in the conventional apparatus described in the above publication, whether the fluctuation in sensor output is due to disturbances or occupants. Could not be determined due to the movement. Therefore, there is a problem that the position of the passenger's hand or face cannot be accurately grasped and the skin temperature of the passenger, which is an important index for air conditioning control, cannot be detected.
[0006]
The present invention has been made in view of the above points, and in a vehicle air conditioner that detects the temperature of each of a plurality of regions including the occupant's face using a plurality of temperature detection elements, distinguishes between disturbances and the movement of the passenger. The object of the present invention is to eliminate the influence of disturbances and to detect the position of the occupant's face.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the apparatus includes a temperature sensor (70) including a plurality of temperature detection elements that detect the temperature of the target region in a non-contact manner, and includes the face of the occupant. In a vehicle air conditioner that detects the temperature of each of a plurality of regions by a plurality of temperature detection elements and performs air conditioning control based on the output signals of the plurality of temperature detection elements, the output change amount of a certain temperature detection element indicates a temperature rise. When the output change amount of the other temperature detection element indicates a temperature decrease, and the temperature detection area where the temperature rises and the temperature detection area where the temperature decreases exist as a set, the face part of the occupant in the temperature detection area where the temperature rises There wherein the position result determined.
[0008]
By the way, when the disturbances entered the temperature detection area and when the face position changed, we examined in detail how the temperature of each area changed. It was found that only the region showed a rapid temperature change and there was almost no temperature change in the other region, in other words, the sudden temperature change in one region due to the disturbance was independent of the other regions. .
[0009]
On the other hand, when the face position changes, the temperature of the face movement destination area increases, and the temperature of the area where the face was located before the movement decreases, in other words, the temperature increases and the temperature decreases. It was found that there is a set area.
[0010]
Therefore, according to the first aspect of the present invention, it is possible to discriminate between the disturbance and the movement of the occupant to eliminate the influence of the disturbance and to detect the position of the occupant's face. Therefore, the passenger | crew's skin temperature which is an important parameter | index of air-conditioning control is detectable.
[0011]
The invention according to claim 2 includes a temperature sensor (70) composed of a plurality of temperature detection elements that detect the temperature of the target region in a non-contact manner, and the temperature for each of the plurality of regions including the occupant's face. In a vehicle air conditioner that detects by a plurality of temperature detection elements and performs air-conditioning control based on output signals of the plurality of temperature detection elements, the output change amount when the output of a certain temperature detection element rises is a positive value. The temperature of the temperature detection element whose output has increased when the output change amount when the output of at least one other temperature detection element has decreased is less than a negative second threshold value. It is determined that the occupant's face is located in the detection area, the output change amount of a certain temperature detection element exceeds the first threshold value, and the output change amounts of all other temperature detection elements are equal to or greater than the second threshold value. At the time of the A certain temperature detection element when the output change amount of a certain temperature detection element is less than the second threshold value and the output change amounts of all other temperature detection elements are less than or equal to the first threshold value. It is characterized in that it is determined that the output drop is caused by a low temperature disturbance.
[0012]
According to this, the same effect as in the first aspect can be obtained.
[0013]
The invention according to claim 3 is characterized in that the first threshold value and the second threshold value are changed according to at least one of the outside air temperature and the amount of solar radiation.
[0014]
By the way, the output change amount due to the face position change changes depending on the outside air temperature and the amount of solar radiation. For example, as the difference between the background temperature of the window glass and the face skin temperature decreases, the output change amount accompanying the face movement decreases. Therefore, according to the invention of claim 3, the face position can be accurately detected regardless of the outside air temperature or the amount of solar radiation.
[0015]
In the invention according to claim 4, the first threshold value and the second threshold value are changed in accordance with the output signal of the temperature detecting element that detects the temperature of the region not including the occupant's face. Features.
[0016]
By the way, the amount of change in output due to the change in face position changes depending on the temperature of the area not including the face. Therefore, according to the invention of claim 4, the face position can be accurately detected regardless of the temperature of the region not including the face portion.
[0017]
In the invention according to claim 5, when the area where the occupant's face is normally located is set as a reference face area in advance, and the temperature difference between the areas is equal to or less than a set value, It is determined that an occupant's face is located in the region.
[0018]
By the way, when the vehicle interior temperature is high, the difference between the temperature of the region including the face portion and the temperature of the region not including the face portion is small, so that it is difficult to accurately determine the face position. Therefore, according to the fifth aspect of the present invention, it is possible to easily determine the face position when the temperature difference between the area including the face portion and the area not including the face portion is small.
[0019]
The invention according to claim 6 is characterized in that the reference face region is changed according to at least one of the sheet position and the mirror orientation.
[0020]
According to this, the face position can be accurately estimated from the sheet position or the mirror orientation, and therefore the reference face area can be accurately set.
[0021]
In the invention according to claim 7, a temperature sensor (70) for detecting the temperature in the passenger compartment in a non-contact manner is provided, air-conditioning control is performed based on a control value calculated from an output signal of the temperature sensor (70), and the temperature sensor When the absolute value of the output change amount of (70) is equal to or greater than the set value, it is determined that the output change of the temperature sensor (70) is due to disturbance, and the control value is corrected by performing time constant processing on the output change amount. When the temperature detected by the temperature sensor (70) is outside the predetermined temperature range, the set value is changed in accordance with at least one of the outside air temperature and the amount of solar radiation. It is characterized by prohibiting the correction.
[0022]
By the way, since there is a large room temperature change at the initial stage of warm-up or cool-down transition, if a disturbance determination is performed in such a case, the possibility of erroneous determination increases. Therefore, as in the seventh aspect of the invention, when the temperature detected by the temperature sensor is outside the predetermined temperature range, the correction of the control value based on the determination of the disturbance is prohibited, so that the air conditioning control by erroneous determination is performed. The influence on can be eliminated.
[0024]
In addition, the code | symbol in the bracket | parenthesis of each said means shows the correspondence with the specific means as described in embodiment mentioned later.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a vehicle air conditioner according to the present invention, and this air conditioner is provided with an air duct 10 that forms an air passage. The air duct 10 has a passenger compartment at a face outlet 11 and a foot outlet 12. 10a is opened.
[0026]
Inside the air duct 10, the inside / outside air switching door 80, blower 20, evaporator (cooling heat exchanger) 30, air mix damper 40, heater core (heating heat exchange) from the air inlet side to the outlets 11 and 12. ) 50 and the outlet switching damper 60 are arranged in order.
[0027]
The inside / outside air switching door 80 switches between the inside and outside air modes, and outside air or inside air is introduced into the air duct 10 according to the rotation position. The blower 20 introduces air from the introduction port into the air duct 10 according to the drive of the blower motor 20a and blows air.
[0028]
The evaporator 30 receives the refrigerant in the refrigeration cycle under the operation of the compressor 30a and cools the air from the blower 20. The compressor 30a is driven by a vehicle engine under selective engagement of an electromagnetic clutch 30b attached thereto.
[0029]
The air mix damper 40 adjusts the amount of air that should flow from the evaporator 30 to the heater 50 and the amount of air that should bypass the heater 50 from the evaporator 30 and flow into the downstream flow. The heater core 50 receives engine cooling water and reheats the air.
[0030]
The blower outlet switching damper 60 switches and sets the blowout mode, and blows air from the foot blower outlet 12 when the face blower outlet 11 is closed as shown by a solid line in FIG. Further, when the air outlet switching damper 60 is in a position to close the foot air outlet 12, air is blown out from the face air outlet 11. Furthermore, when the blower outlet switching damper 60 is in a position where both the blower outlets 11 and 12 are open, air is blown out from both the blower outlets 11 and 12.
[0031]
The air conditioner includes a temperature sensor 70, an inside air temperature sensor 71 (which may be omitted), opening degree sensors 72 to 74, and various sensors (not shown). The temperature sensor 70 is a predetermined area in the vehicle interior 10a. The surface temperature is detected in a non-contact manner to generate a surface temperature signal, the internal air temperature sensor 71 detects the air temperature in the passenger compartment 10a to generate an internal air temperature signal, and the opening sensors 72 to 74 are air mixes. The actual opening of the damper 40, the outlet switching damper 60, and the inside / outside air switching door 80 is detected to generate an opening signal.
[0032]
The operation panel 150 generates various setting signals that are inputs from the passengers to the air conditioner, that is, a set temperature signal, a mode selection signal, an auto / manual selection signal, and the like.
[0033]
The ECU 90 executes a program stored in advance in a ROM (not shown), and during this execution, the drive circuits 100, 110, 120 connected to the blower motor 20a, the electromagnetic clutch 30b, and the three motors 120a, 130a, 140a, respectively. Arithmetic processing necessary for controlling 130 and 140 is performed.
[0034]
The drive circuit 100 is controlled by the ECU 90 to control the rotational speed of the blower motor 20a. The drive circuit 110 is controlled by the ECU 90 to selectively engage the electromagnetic clutch 30b. The three motors 120a, 130a, 140a are driven to rotate by the drive circuits 120, 130, 140 under the control of the ECU 90.
[0035]
Further, the electromagnetic clutch 30b is driven and engaged by the drive circuit 110 in response to the output signal from the ECU 90, and the compressor 30a is driven by the engine along with this to supply the refrigerant to the evaporator 30.
[0036]
Next, the temperature sensor 70 will be described. As shown in FIG. 1, the temperature sensor 70 is installed on the ceiling in the vicinity of the rearview mirror in front of the driver M, and detects the surface temperature of the body of the driver M and the surrounding rear.
[0037]
The temperature sensor 70 is configured by arranging a large number (16 in this example) of temperature detection elements in a matrix of 4 rows and 4 columns on one base. The 16 temperature detecting elements independently detect the surface temperature of each of the 16 areas (hereinafter referred to as pixels) of the temperature detecting area 160 shown in FIG. 2, and correspond to the output signals of the temperature detecting elements. Generate a temperature signal. In addition, the numbers 1-16 in FIG. 2 are numbers of each pixel.
[0038]
The temperature sensor 70 is an infrared sensor that generates an electrical signal corresponding to the amount of infrared rays radiated from the test temperature body. More specifically, the temperature sensor 70 generates an electromotive force proportional to the amount of infrared rays radiated from the test temperature body. This is an infrared sensor using a thermopile detection element.
[0039]
In the above configuration, the engine of the vehicle is started by closing the ignition switch IG and the ECU 90 is put into an operating state.
[0040]
Next, the ECU 90 starts execution of the program, and the ECU 90 controls the control target temperature of the air blown into the passenger compartment 10a based on operation signals from the operation panel 150 and signals from various sensors, that is, a target outlet temperature (hereinafter referred to as a target outlet temperature). (Referred to as TAO).
[0041]
Next, the ECU 90 calculates the applied voltage to the blower motor 20a and the target opening degree of the air mix damper 40 based on the operation signal, TAO, and signals from various sensors, and the inside / outside air mode, the blowing mode, and the electromagnetic clutch 30b. Determine on-off.
[0042]
Next, the ECU 90 causes the drive circuits 100, 120, 130, and 140 to send a blower voltage control signal, an air mix damper opening control signal, an inside / outside air mode control signal, a blow mode control signal, and a clutch control to the drive circuits 100, 120, 130, and 140. Each signal is output.
[0043]
By the way, since a passenger | crew's skin temperature has a correlation with a passenger | crew's thermal sensation, a passenger | crew's skin temperature is made into the important parameter | index of air-conditioning control. Specifically, air conditioning control that matches the occupant's thermal sensation is performed by calculating the TAO by weighting the temperature signal of the occupant's face. Therefore, it is necessary to determine in which pixel in the temperature detection area 160 the occupant's face is located even when a disturbance enters the temperature detection area 160 or the position of the occupant's face changes. .
[0044]
Hereinafter, a method for determining a disturbance object and an occupant face position will be described. FIGS. 3 and 4 show examples of temperature changes of three typical pixels 6, 10, 15 in the temperature detection region 160. Incidentally, in a state where the driver M maintains the normal sitting posture, the headrest and seat of the driver's seat are located at the pixel 6, the face of the driver M is located at the pixel 10, and the driver is driven at the pixel 15. The window glass next to the seat is located.
[0045]
FIG. 3 shows a case where a high-temperature object such as a cigarette or a warm beverage enters the temperature detection region 160. When the high-temperature object is located near the mouth, only the temperature of the pixel 10 is an abrupt temperature. In addition to showing the change, the other pixels 6 and 15 have almost no temperature change. In other words, the sudden temperature change of one pixel due to the disturbance is independent of the other pixels.
[0046]
On the other hand, FIG. 4 shows a case where the driver M has confirmed the right and left and the rear and the face position has changed. When checking left and right, the driver M moves the upper body forward to check the face, so that the face moves from the pixel 10 to another pixel. As a result, the temperature of the pixel 10 decreases. Further, as the driver M moves forward, the arm of the driver M is positioned at the pixel 15 and the temperature of the pixel 15 rises.
[0047]
At the time of the backward confirmation, when the driver M turns back, the face moves from the pixel 10 to the pixel 6 and the temperature of the pixel 6 rises, and the arm of the driver M is positioned at the pixel 15 and the pixel 15 The temperature of 15 also rises. Further, the seat of the driver's seat and the shoulder of the driver M are located at the pixel 10, and the temperature of the pixel 10 is lowered.
[0048]
In this way, when the face position changes, the temperature of the pixel to which the face is moved increases, and the temperature of the pixel where the face was located before the movement decreases. There is a set of pixels that fall.
[0049]
Therefore, it is possible to determine whether or not the object is a disturbance object and to determine the face position based on how the pixels 1 to 16 change in temperature. Hereinafter, specific methods of disturbance object determination and face position determination will be described. 5 will be described. FIG. 5 is a flowchart of a portion related to disturbance determination and face position determination in the program executed by the ECU 90.
[0050]
Here, the temperature signal of each pixel is sampled every 250 msec, and an average value of 16 sampling values is set as a control value Tpi (16). Note that the control value Tpi (16) is used for the calculation of TAO when disturbance processing described later is not performed.
[0051]
Further, the temperature change amount ΔTpi of each pixel used as the determination parameter is calculated from the latest control value Tpi (16) New and the previous control value Tpi (16) Old, ΔTpi = Tpi (16) New−Tpi (16). It is determined by the Old formula. The temperature change amount ΔTpi corresponds to the output change amount of the temperature detection element.
[0052]
In FIG. 5, in step S100, it is determined whether or not the temperature change amount ΔTpi of the pixel i exceeds a first threshold value Tth1 of a positive value set to 2 ° C., for example, and exceeds the first threshold value Tth1. When the temperature rise is indicated, step S100 is YES and the process proceeds to step S110.
[0053]
In step S110, it is determined whether or not the temperature change amount ΔTpj of the other pixel j is less than the negative second threshold value Tth2 set to −2 ° C., for example, and even one of the other pixels j is determined. If there is a temperature drop less than the second threshold value Tth2, step S110 is YES.
[0054]
Thus, if both step S100 and step S110 are YES, that is, if pixel i indicating a large temperature increase and pixel j indicating a large temperature decrease exist as a set, the face position is determined to be a pixel in step S150. It is determined that the pixel has moved from j to pixel i.
[0055]
Next, if step S110 is NO, that is, if the temperature change amount ΔTpj of the other pixel j is not less than the second threshold value Tth2, step S110 is NO.
[0056]
As described above, when step S100 is YES and step S110 is NO, that is, there is a pixel i indicating a large temperature increase but there is no pixel j indicating a large temperature decrease, the temperature increase of the pixel i is a disturbance of a hot object. The disturbance process is performed in step S130. This disturbance processing will be described later.
[0057]
Next, in step S100, when the temperature change amount ΔTpi of all the pixels i indicates the first threshold value Tth1 or less, step S100 is NO and the process proceeds to step S120.
[0058]
In step S120, it is determined whether or not the temperature change amount ΔTpj of the pixel j is less than the second threshold value Tth2, and if there is even one pixel j indicating a temperature decrease less than the second threshold value Tth2, step S120 is performed. Becomes YES.
[0059]
As described above, when step S100 is NO and step S120 is YES, that is, there is a pixel j indicating a large temperature decrease, but there is no pixel i indicating a large temperature increase, the temperature decrease of the pixel j is a disturbance of a low temperature object. The disturbance process is performed in step S140.
[0060]
Next, the disturbance process in steps S130 and S140 will be described. FIG. 6 is a flowchart of a portion related to the disturbance processing in steps S130 and S140 in the program executed by the ECU 90.
[0061]
If it is determined in FIG. 6 that the disturbance is present, the control value Tpi (16) is corrected with a time constant τ = 60 sec in step S160. Next, in step S170, the corrected control value is output. The ECU 90 uses the corrected control value when calculating TAO. This prevents or suppresses the air conditioning control from becoming unstable due to the influence of disturbance.
[0062]
Next, in step S180, it is determined whether or not the temperature change amount ΔTpi of the pixel i is not more than the first threshold value Tth1 and not less than the second threshold value Tth2, and if NO, steps S160 and S170 are performed. Repeat the process. On the other hand, when step S180 is YES, it is determined that the disturbance has disappeared, and the disturbance process is terminated.
[0063]
In this embodiment, a sudden temperature change of a pixel due to a disturbance occurs independently of other pixels, and when the face position changes, a pixel whose temperature increases and a pixel whose temperature decreases are set. And using this characteristic, it is determined whether or not the object is a disturbance object and the position of the occupant's face.
[0064]
Therefore, it is possible to discriminate between the disturbance and the movement of the occupant to eliminate the influence of the disturbance and to detect the position of the occupant's face. Therefore, the passenger | crew's skin temperature which is an important parameter | index of air-conditioning control is detectable.
[0065]
(Other embodiments)
1. In the above embodiment, the average value of the 16 sampling values is set as the control value Tpi (16), and the temperature change amount ΔTpi as the determination parameter is set to the latest control value Tpi (16) New and the previous control value Tpi (16). The temperature change amount ΔTpi is obtained from the latest sampling value and the previous control value Tpi (16) Old, but the process can be performed more quickly.
[0066]
2. The temperature change amount ΔTpi due to the change in the face position changes depending on the outside air temperature and the amount of solar radiation. For example, as the difference between the background temperature of the window glass or the like and the face skin temperature decreases, the temperature change amount ΔTpi accompanying the face movement decreases. Therefore, by changing the first threshold value Tth1 and the second threshold value Tth2 in the embodiment according to at least one of the outside air temperature and the amount of solar radiation, the face position can be set regardless of the outside air temperature or the amount of solar radiation. It can be detected accurately.
[0067]
Similarly, by changing the first threshold value Tth1 and the second threshold value Tth2 in the above-described embodiment according to the temperature signal of pixels other than the face, for example, the temperature signal of pixels such as a window glass and a ceiling, the face portion is changed. Regardless of the temperature of the pixel that is not included, the face position can be accurately detected.
[0068]
3. When the vehicle interior temperature is high, it is difficult to accurately determine the face position because the difference between the temperature of the pixel including the face portion and the temperature of the pixel not including the face portion is small. Therefore, a pixel in which the face is normally located is preset as a reference face pixel, and when the temperature difference between a large number of pixels is equal to or less than a set value, it is determined that the face is located at the reference face pixel. The face position can be easily determined when the temperature difference between the pixel including the pixel and the pixel not including the face portion is small.
[0069]
At this time, since the face position can be accurately estimated from the sheet position or the mirror direction, the reference face pixel is changed according to at least one of the sheet position and the mirror direction. Can be set accurately.
[0070]
4). Since the room temperature changes greatly at the initial stage of warm-up and cool-down transitions, if a disturbance determination is made at such times, the possibility of erroneous determination increases. Therefore, the temperature of a part where the temperature largely changes depending on the room temperature, for example, the pixel temperature such as a sheet, clothing, or ceiling, does not affect the air conditioning control, that is, the maximum cooling or maximum heating is continued. In this case, it is desirable not to perform disturbance determination or disturbance processing.
[0071]
Specifically, when the temperature of a pixel such as a sheet is, for example, −10 ° C. or less or 50 ° C. or more, in other words, when the temperature of a pixel such as a sheet is outside a predetermined temperature range, disturbance determination is prohibited or disturbance Even if it is determined, it is possible to eliminate the influence on the air-conditioning control due to the erroneous determination by prohibiting the correction of the control value. In addition, the determination value (setting value of Claim 7) determined to be disturbance may be changed according to at least one of the outside air temperature and the amount of solar radiation.
