Description

[Technical Field]

[0001] The present invention relates to a vehicle air conditioning control device that has a simple configuration and is capable of estimating the temperature inside a vehicle cabin and controlling air conditioning without being affected by a heat source or a blower air volume. [Background technology]

[0002] A vehicle air conditioner (hereinafter referred to as an air conditioner) generates conditioned air by driving a blower motor arranged in a duct using a control means, and controls the temperature of the conditioned air blown into the passenger compartment using a temperature adjustment means such as an air mix door so that the temperature inside the passenger compartment detected by an inside air temperature sensor becomes a predetermined target temperature.

[0003] Here, the air conditioner controller is installed on the instrument panel inside the vehicle, and the vehicle occupants operate multiple air conditioner operation switches located on the front of the controller housing to set the target temperature, the air conditioning air outlet strength, and the air outlet switching settings, and the operating status of the air conditioner is displayed on the LCD display located on the front of the controller housing.

[0004] In some vehicle models, an inside air temperature sensor such as a thermistor is disposed inside the controller housing. For example, a slit-shaped opening that connects to the interior of the vehicle cabin is formed at the right end of the front face of the controller housing, and this opening is connected to the inside of the air conditioner duct by a connecting pipe such as an aspirator hose. An inside air temperature sensor is disposed at the end of the connecting pipe on the opening side. When the air conditioner's blower motor is activated, conditioned air is blown into the vehicle cabin, creating negative pressure inside the connecting pipe, causing air from inside the vehicle cabin to flow into the connecting pipe. The inside air temperature sensor detects the temperature of the air inside the vehicle cabin flowing through the opening into the connecting pipe. In the air conditioner's automatic control mode, a target outlet temperature is calculated based on the user-set temperature, the inside air temperature, and other factors, and the compressor and various servo motors are controlled to achieve this target outlet temperature.

[0005] In a conventional configuration in which a connecting pipe connects the inside of the controller housing to the inside of the air conditioner duct and an inside air temperature sensor such as a thermistor is located at the open end of the connecting pipe, heat sources such as electronic components and light sources inside the controller housing generate heat when power is applied, trapping heat inside the housing and raising the temperature inside the housing. Therefore, if an inside air temperature sensor is located inside the controller housing, the temperature detected by the inside air temperature sensor will be affected. Conversely, negative pressure generated by the operation of the air conditioner's blower motor causes heat trapped inside the housing to be released into the duct, which is also affected by the heat dissipation from the housing itself. This can result in inaccurate detection of the inside air temperature due to heat generation and heat dissipation conditions. On the other hand, if the blower airflow is reduced and the negative pressure in the connecting pipe is insufficient, the air inside the vehicle cabin cannot be drawn in, resulting in the temperature detected near the heated controller, making accurate measurement of the inside air temperature difficult.

[0006] Therefore, Patent Document 1 discloses a vehicle air conditioning control device that corrects the inside air temperature detected by an inside air temperature sensor in consideration of the amount of heat generated by the heat source and the amount of heat dissipated near the inside air temperature sensor. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2020-138580 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the inside air temperature sensor described in Patent Document 1 corrects the inside air temperature by taking into account the heat generation amount of the heat source and the heat dissipation amount near the inside air temperature sensor. Therefore, there is a problem that complex temperature correction is required depending on the structure and installation location of the inside air temperature sensor, and there is a low degree of freedom in the installation location.

[0009] The present invention has been made in consideration of the above, and aims to provide an air conditioning control device for a vehicle that has a simple configuration and can estimate the internal temperature inside the vehicle cabin and perform air conditioning control without being affected by heat sources or blower air volume. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems and achieve the objectives, the vehicle air conditioning control device of the present invention is a vehicle air conditioning control device that controls the air conditioning inside the vehicle cabin, and is equipped with a temperature measurement unit that measures the temperature inside the vehicle cabin, a temperature acquisition unit that acquires the temperature of the vehicle inside the vehicle cabin and the temperature of an object inside the vehicle cabin using the temperature measurement unit, and an estimated interior air temperature determination unit that determines an estimated interior air temperature inside the vehicle cabin based on the temperature of the vehicle and the temperature of the object and the state of the air outlet temperature of the vehicle cabin air conditioning.

[0011] In addition, in the vehicle air conditioning control device of the present invention, in the above invention, the temperature measurement unit is an infrared sensor, and the temperature acquisition unit acquires the surface temperature of the vehicle in the passenger compartment and the surface temperatures of objects including occupants in the passenger compartment.

[0012] In addition, the vehicle air conditioning control device of the present invention, in the above invention, includes a sensible temperature calculation unit that calculates a sensible temperature based on the estimated interior air temperature and the surface temperature of the object inside the vehicle cabin, an air outlet determination unit that determines one or more air outlets from which to blow out conditioned air according to a target sensible temperature that is a user-set temperature, and an air conditioning control unit that blows out the conditioned air from the one or more air outlets determined by the air outlet determination unit. [Effects of the Invention]

[0013] According to the present invention, it is possible to estimate the temperature inside the vehicle cabin and control air conditioning using a simple configuration without being affected by the heat source or the blower air volume. [Brief explanation of the drawings]

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle air conditioning control device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] <Overall structure> Fig. 1 is a schematic diagram showing the general configuration of a vehicle air conditioning control device 1 according to this embodiment. As shown in Fig. 1, the vehicle air conditioning control device 1 includes a duct 2 that sends conditioned air into the vehicle cabin, and a blower fan 4 driven by a blower motor 3 that is controlled to multiple levels of strength by an air conditioner ECU (Electronic Control Unit) 29 (described later), an evaporator 5, an air mix door 6, and a heater core 7, which are arranged in this order from the upstream side of the air flow path.

[0017] An inside air inlet 9 and an outside air inlet 10 are formed on the inlet side of the duct 2, which is upstream of the blower fan 4. When a vehicle occupant operates an inside / outside air selector switch provided in the air conditioner ECU 29, an inside / outside air selector damper servo motor 11 controlled by the air conditioner ECU 29 drives an inside / outside air selector damper 12 provided inside the inside air inlet 9 and the outside air inlet 10. Either the inside air inlet 9 or the outside air inlet 10 is opened and the other is closed, so that either the inside air or the outside air is introduced into the duct 2.

[0018] The evaporator 5 is disposed downstream of the blower fan 4 midway through the refrigeration cycle, and when a vehicle occupant turns on an air conditioner power switch (hereinafter referred to as the air conditioner switch) provided on the air conditioner ECU 29, a compressor (not shown) is connected to the engine and driven by the rotation of the engine to compress the refrigerant, the refrigerant in a high-temperature, high-pressure state dissipates heat in a condenser (not shown), and the refrigerant with dissipated heat flows into the evaporator 5 via an expansion valve (not shown) and vaporizes, thereby exchanging heat with the air flowing through the evaporator 5 and in the duct 2, thereby cooling it. An evaporator fin temperature sensor 13 is disposed downstream of the evaporator 5 to detect the temperature of the evaporator fins, and a detection signal from the evaporator fin temperature sensor 13 is input to the air conditioner ECU 29.

[0019] The heater core 7 is disposed downstream of the evaporator 5 so as to block a portion of the duct 2. Engine coolant flows through the heater core 7 via a pipe, and the inside air or outside air is heated as it passes through the heater core 7. At this time, the air mix door 6 provided at the air inlet of the heater core 7 is driven by an air mix door servo motor 14 controlled by the air conditioner ECU 29 to control the opening and closing of the air mix door 6 and adjust the opening degree of the air inlet of the heater core 7, thereby controlling the temperature at which the inside air or outside air is heated by the heater core 7.

[0020] Here, the state in which the air mix door 6 fully closes the air inlet of the heater core 7 is the so-called MAX cool control state (opening 0%), and the state in which the air mix door 6 opens the air inlet of the heater core 7 and fully closes the passage in the duct 2 in which the heater core 7 is not located (the air inlet is fully open) is the so-called MAX hot control state (opening 100%).When the air mix door 6 is controlled to the cool side, most of the air cooled through the evaporator 5 flows downstream, and when the air mix door 6 is controlled to the hot side, the air that has passed through the evaporator 5 is heated by the heater core 7 and then flows downstream.

[0021] At the most downstream portion of the duct 2, a defroster outlet 15, a face outlet 16, and a foot outlet 17 are formed, and the opening and closing of each outlet is controlled by dampers 21, 22, and 23, which are respectively driven by servo motors 18, 19, and 20, which are controlled by an air conditioner ECU 29.

[0022] An occupant of the vehicle can select either the automatic control mode or the manual control mode by operating an air conditioning operation mode selector switch (hereinafter simply referred to as the mode selector switch) provided in the air conditioning ECU 29. When the manual control mode is selected, the air conditioning ECU 29 controls the servo motors 18, 19, and 20 to control the opening degrees of the dampers 21, 22, and 23 each time an air outlet mode selector switch provided in the air conditioning ECU 29 is operated, and the air outlet mode is switched sequentially (cyclically) among a face mode in which conditioned air is blown only from the face outlet 16 toward the upper body of the occupant, a bi-level mode in which conditioned air is blown only from the face outlet 16 toward the upper body of the occupant and from both the face outlet 16 and the foot outlet 17 toward the occupant's feet, a foot mode in which conditioned air is blown only from the foot outlet 17 toward the occupant's feet, and a foot / def mode in which conditioned air is blown only from the foot outlet 17 toward the occupant's feet and from both the foot outlet 17 and the defroster outlet 15 toward the occupant's feet and the windshield, thereby controlling the air conditioning in the manual control mode.

[0023] As shown in FIG. 1, a solar radiation sensor 25 for detecting the amount of solar radiation is disposed near the rearview mirror (not shown) on the inner surface of the windshield, and a temperature measuring unit 26 for detecting the temperature inside the vehicle cabin, an engine water temperature sensor 27 for detecting the temperature of the engine coolant, and an outside air temperature sensor 28 for detecting the outside air temperature outside the vehicle cabin are also provided. These detection signals are input to an air conditioning ECU 29.

[0024] Here, the air conditioning ECU 29 is housed in a housing 30 disposed on the instrument panel inside the vehicle cabin. A temperature measurement unit 26 is disposed on the left end of the front of this housing 30. The temperature measurement unit 26 is an infrared sensor that captures an image of the temperature distribution inside the vehicle cabin. The temperature measurement unit 26 only needs to detect the temperature inside the vehicle cabin in a non-contact manner. The temperature measurement unit 26 does not need to be provided in the housing 30, and can be installed anywhere as long as it can capture an image of the temperature distribution inside the vehicle cabin.

[0025] Here, the air conditioner ECU 29 is composed of a microcomputer having a CPU and a memory. As shown in FIG. 1, the front panel of a housing 30 of the air conditioner ECU 29 is provided with an air conditioner switch (air conditioner power switch) 32 for starting and stopping the air conditioner, as well as an automatic mode selection switch 33 and a manual mode selection switch 34 for selecting the air conditioner's operating mode between automatic control mode and manual control mode, respectively. Operation signals of these switches are input to the air conditioner ECU 29. In addition, the front panel of the housing 30 is provided with a blowout mode changeover switch 35 for switching the open / closed states of the defroster outlet 15, face outlet 16, and foot outlet 17 to switch the blowout mode in the order of face mode, bi-level mode, foot mode, and foot / def mode, and a temperature setting switch 36 for setting the air conditioning temperature. Operation signals of these switches are input to the air conditioner ECU 29.

[0026] Furthermore, the front panel of the housing 30 is provided with an air volume switch 37 and an inside / outside air selector switch 38 for switching between multiple levels of airflow volume. Operation signals of the air volume switch 37 and the inside / outside air selector switch 38 are input to the air conditioner ECU 29, which controls the operation of the blower motor 3 in response to the operation signal of the air volume switch 37. In response to the operation signal of the inside / outside air selector switch 38, the air conditioner ECU 29 drives and controls the inside / outside air selector damper servo motor 11 to open either the inside air inlet 9 or the outside air inlet 10, thereby opening and closing the inside air inlet 9 and the outside air inlet 10 via the inside / outside air selector damper 12. Furthermore, as described above, the air conditioner ECU 29 drives and controls the air mix door servo motor 14 to open and close the air mix door 6, and adjusts the opening of the air inlet of the heater core 7, thereby controlling the heating temperature of the inside air or the outside air by the heater core 7. A liquid crystal display 39 for displaying the operating status of the air conditioner is located at the top center of the front panel.

[0027] <Internal structure of the air conditioning ECU> Fig. 2 is a functional block diagram showing the internal configuration of the air conditioner ECU 29. As shown in Fig. 2, the air conditioner ECU 29 has a temperature acquisition unit 101, an estimated inside air temperature determination unit 102, a sensible temperature calculation unit 103, an air outlet determination unit 104, and an air conditioning control unit 105. The temperature distribution map D is acquired by the temperature acquisition unit 101 via the temperature measurement unit 26.

[0028] The temperature acquisition unit 101 acquires the temperature (surface temperature) of the vehicle in the vehicle compartment and the temperatures (surface temperatures) of objects in the vehicle compartment, including the occupants, via the temperature measurement unit 26. Here, the vehicle temperature refers to the temperature of parts that constitute the frame of the vehicle, such as the ceiling and glass. The object temperature refers to the temperature of the seats, occupants (clothing), etc.

[0029] FIG. 3 is a diagram showing an example of a temperature distribution map D acquired by the temperature acquisition unit 101. As shown in FIG. 3, the temperature distribution map D includes a ceiling region 40, seat regions 41, 41a, glass window regions 42, 42a, and a passenger region 43, and the surface temperatures of each of the regions 40 to 43 can be obtained. Specifically, the average temperature of each pixel in each of the regions 40 to 43 is calculated as the surface temperature of each of the regions 40 to 43. Note that each of the regions 40 to 43 may be determined by image filtering, for example, edge processing, or a rectangular region may be set in advance within each of the regions 40 to 43.

[0030] The estimated interior air temperature determination unit 102 determines the estimated interior air temperature in the vehicle cabin based on the vehicle temperature, the object temperature, and the temperature state of the air outlet of the vehicle cabin air conditioning. The temperature of the air outlet of the vehicle cabin air conditioning is specifically the target air outlet temperature (TAO).

[0031] The sensible temperature calculation unit 103 calculates the sensible temperature of the occupant based on the estimated inside air temperature determined by the estimated inside air temperature determination unit 102 and the surface temperatures of objects in the vehicle cabin. For example, if the surface temperature of the seat in area 41 is higher than the estimated inside air temperature, the sensible temperature of the occupant is calculated to be higher than the estimated inside air temperature. This sensible temperature may be calculated using a predetermined calculation formula or a sensible temperature map.

[0032] The outlet determination unit 104 determines one or more outlets from which to blow out conditioned air, from among the multiple air conditioning outlets, in accordance with the target sensible temperature, which is a temperature set by the user. For example, if the target sensible temperature is equal to or lower than a predetermined value, it determines to blow out conditioned air from both the face outlet 16 and the foot outlet 17 in bi-level mode, if the target sensible temperature is a temperature that tends to cool, it determines to blow out conditioned air only from the face outlet 16 in face mode, and if the target sensible temperature is not a temperature that tends to cool, it determines to blow out conditioned air only from the foot outlet 17 in foot mode.

[0033] The air conditioning control unit 105 controls various servo motors and compressors to control the sensible temperature to the target sensible temperature, and blows conditioned air from one or more air outlets determined by the air outlet determination unit.

[0034] <Air conditioning control processing> Fig. 4 is a flowchart showing the air conditioning control processing procedure performed by the air conditioner ECU 29. As shown in Fig. 4, the air conditioner ECU 29 first acquires the temperature of the vehicle inside the vehicle compartment and the temperatures of objects inside the vehicle compartment (step S101). That is, it acquires a temperature distribution map D. Then, it estimates the inside air temperature from the surface temperature of the ceiling, which is one of the vehicle temperatures (step S102). This inside air temperature estimation is performed based on the correlation between the surface temperature of the ceiling and the inside air temperature. Specifically, it is obtained using an inside air temperature estimation map or a predetermined calculation formula.

[0035] Then, the estimated inside air temperature is corrected to obtain a corrected estimated inside air temperature (step S103). The estimated inside air temperature is corrected because the estimated inside air temperature differs from the actual inside air temperature during the transition period when air conditioning control starts to cool or heat the vehicle. Specifically, the correction is performed according to the TAO correction.

[0036] Thereafter, the sensible temperature is calculated from the corrected estimated inside air temperature and the surface temperature of the object (step S104). This sensible temperature is also determined based on the correlation between the corrected estimated inside air temperature and the surface temperature of the object and the sensible temperature, for example, using a sensible temperature map or a predetermined calculation formula.

[0037] Thereafter, the temperature set by the user is set as the target sensible temperature, and it is determined whether the target sensible temperature is equal to or lower than a predetermined value (step S105). If the target sensible temperature is equal to or lower than the predetermined value (step S105: Yes), the air outlet is determined to be in the high level (B / L) mode, and a determination is made to blow conditioned air from both the face air outlet 16 and the foot air outlet 17 (step S106), and the process proceeds to step S110.

[0038] On the other hand, if the target sensible temperature is not equal to or lower than the predetermined value (step S105: No), it is further determined whether the target sensible temperature is a temperature on the cooling side (step S107). If the target sensible temperature is a temperature on the cooling side (step S107: Yes), the air outlet is determined to be in face (FACE) mode, and a determination is made to blow conditioned air only from face air outlet 16 (step S108), and the process proceeds to step S110.

[0039] If the target sensible temperature is not the cooling temperature (step S107: No), the air outlet is determined to be in foot mode, and a determination is made to blow conditioned air only from foot air outlet 17 (step S109), and the process proceeds to step S110.

[0040] Then, in step S110, various servo motors and compressors are controlled to control the sensible temperature to the target sensible temperature, and air conditioning control is performed to blow out conditioned air from the determined air outlet, and this process ends. Note that this process is repeated at predetermined time intervals.

[0041] <Estimated indoor temperature correction process> 5 is a detailed flowchart of the correction process of the estimated inside air temperature in step S103. As shown in FIG. 5, the air conditioner ECU 29 calculates the TAO based on the estimated inside air temperature (step S201). Then, it is determined whether the previous TAO is the temperature on the cooling side (step S202). Here, the previous TAO is the TAO calculated in the previous routine, and in the case of the initial routine, it is the initial value.

[0042] If the previous TAO is the temperature of the cooling side (step S202: Yes), the estimated inside air temperature is corrected based on the cooling side TAO correction (step S203), and the corrected estimated inside air temperature is determined based on this correction (step S206), and the process returns to step S103.

[0043] If the previous TAO is not the cooling side temperature (step S202: No), it is further determined whether the previous TAO is the heating side temperature (step S204). If the previous TAO is the heating side temperature (step S204: Yes), the estimated inside air temperature is corrected based on the heating side TAO correction (step S205), and the corrected estimated inside air temperature is determined based on this correction (step S206), and the process returns to step S103.

[0044] On the other hand, if the previous TAO is not the temperature on the heating side (step S204: No), no correction is made, and the estimated office work temperature is determined as the corrected estimated indoor air temperature (step S206), and the process returns to step S103.

[0045] <Modification of Estimated Inside Air Temperature Correction Process> 6 is a detailed flowchart of the correction process of the estimated inside air temperature in step S103 according to a modified example. In this modified example, the correction process is not performed based on the TAO correction, but is performed using a correction map. As shown in FIG. 6, first, the air conditioner ECU 29 calculates the TAO based on the estimated inside air temperature (step S301).

[0046] Then, using the correction map M10, the current air outlet, the current blower air volume, and the surface temperature distribution of the object are input to the correction map M10, and the estimated inside air temperature corrected by the correction map M10 is output (step S302). Then, the corrected estimated inside air temperature is determined as the corrected estimated inside air temperature (step S303), and the process returns to step S103.

[0047] Here, the correction map M10 has three input variables: the current air outlet, the current blower airflow rate, and the surface temperature distribution of the object, and one output variable: the corrected estimated inside air temperature. Creating the map takes time, but once the map is created, correction processing can be performed quickly. Note that it is also possible to create and use a correction map that deletes the current air outlet from the three input variables and has only two input variables.

[0048] In the above embodiment, the inside air temperature is estimated using the temperature measurement unit 26 such as an infrared sensor, so it is possible to estimate the inside air temperature in the vehicle cabin and control the air conditioning with a simple configuration without being affected by heat sources or blower air volume. The temperature measurement unit 26 can be installed in any location, making it easy to design the vehicle interior.

[0049] Furthermore, in this embodiment, the occupant's sensible temperature can be calculated with high accuracy using a small number of temperature measuring units 26, and the occupant's sensible temperature can be used to reduce temperature perception errors by setting the user-set temperature as the target sensible temperature. In particular, since the target temperature, which is the user-set temperature, is controlled as the sensible temperature (target sensible temperature) rather than the air temperature, excessive cooling can be prevented.

[0050] Furthermore, in this embodiment, the air outlet is determined, and for example, the cool-down in the bi-level mode assumed in the summer can reduce the annoyance of the air conditioning air blowing on the face compared to the conventional air conditioning control that blows the air conditioning air only from the face air outlet in the face mode. Furthermore, assuming that the feet are lightly dressed in the summer, the feeling of cooling can be felt earlier than with the conventional air conditioning control.

[0051] In the above embodiment, one infrared sensor is provided as the temperature measurement unit 26, but multiple infrared sensors may be provided, and when multiple sensors are provided, the imaging ranges may be different. For example, one infrared sensor may image mainly the front seats in the first row, and another infrared sensor may image mainly the rear seats in the second and third rows. Furthermore, when multiple vehicle air conditioning control devices are installed in a vehicle, the air conditioning target areas of each vehicle air conditioning control device may be imaged by different infrared sensors.

[0052] Furthermore, in the above embodiment, an automobile is used as an example of a vehicle, but the present embodiment can also be applied to the interior of various moving bodies such as a train or an airplane.

[0053] Furthermore, the configurations illustrated in the above-described embodiments and modifications are merely functional schematics and do not necessarily have to be physically configured as shown. In other words, the distribution and integration of each device and component is not limited to that illustrated, and all or part of them can be functionally or physically distributed and integrated in any unit depending on various usage situations, etc. [Explanation of symbols]
