In the present embodiment, the vehicle air conditioner 1 is applied to a hybrid vehicle that obtains driving force for vehicle travel from an internal combustion engine (engine) EG and a travel electric motor.

  First, the hybrid vehicle of this embodiment will be described. The hybrid vehicle of this embodiment is configured as a so-called plug-in hybrid vehicle that can charge the battery 81 in FIG. 1 with electric power supplied from an external power source (commercial power source) when the vehicle is stopped. In this plug-in hybrid vehicle, the battery 81 is charged from an external power source when the vehicle is stopped before the vehicle starts running. When this is the case, the vehicle travels mainly by the driving force of the traveling electric motor (hereinafter, this operation mode is referred to as an EV operation mode).

  On the other hand, when the remaining amount of power stored in the battery 81 is lower than the reference running remaining amount during vehicle travel, the vehicle travels mainly by the driving force of the engine EG (hereinafter, this operation mode is referred to as the HV operation mode). In this way, by switching between the EV operation mode and the HV operation mode, the fuel consumption of the engine EG is suppressed and the vehicle fuel consumption is improved with respect to a normal vehicle that obtains driving force for vehicle travel only from the engine EG. I am letting.

  Further, the driving force output from the engine EG is used not only for driving the vehicle but also for operating the generator 80 of FIG. And the electric power generated with the generator 80 and the electric power supplied from the external power supply can be stored in the battery 81, and the electric power stored in the battery 81 is not only a traveling electric motor but also a vehicle air conditioner. 1 can be supplied to various in-vehicle devices including an electric component device that constitutes 1.

  Next, the detailed structure of the vehicle air conditioner 1 of this embodiment is demonstrated. The vehicle air conditioner 1 includes an indoor air conditioning unit 10 shown in FIG. 1 and an air conditioning control device 50 as a control means shown in FIG.

Arranged inside. And the indoor air conditioning unit 10 accommodates the air blower 12, the evaporator 13, the heater core 14, the PTC heater 15, etc. in the casing 11 which forms the outer shell.

  The casing 11 forms an air passage for the blown air blown into the vehicle interior, and is formed of a resin (for example, polypropylene) having a certain degree of elasticity and excellent strength. On the most upstream side of the blown air flow in the casing 11, an inside / outside air switching box 20 for switching and introducing inside air (vehicle compartment air) and outside air (vehicle compartment outside air) is disposed.

  More specifically, the inside / outside air switching box 20 is formed with an inside air introduction port 21 for introducing inside air into the casing 11 and an outside air introduction port 22 for introducing outside air. Furthermore, inside the inside / outside air switching box 20, the entire area of the air introduced into the casing 11 from the inside air introduction port 21 and the outside air introduction port 22 is adjusted by continuously adjusting the opening areas of the inside air introduction port 21 and the outside air introduction port 22.

To do. And the refrigerant | coolant discharge capability of the compressor 31 is changed by this rotation speed control. On the other hand, the inverter 61 outputs a signal indicating the power consumption Wcp of the compressor 31 to the air conditioning control device 50.

  The condenser 32 shown in FIG. 1 is disposed in the engine room, and compresses by exchanging heat between the refrigerant circulating inside and the air outside the vehicle (outside air) blown from the blower fan 35 as an outdoor blower. The condensed refrigerant is liquefied. The blower fan 35 is an electric blower in which the operating rate, that is, the rotation speed (the amount of blown air) is controlled by the control voltage output from the air conditioning control device 50.

  The gas-liquid separator 33 gas-liquid separates the condensed and liquefied refrigerant and flows only the liquid refrigerant downstream. The expansion valve 34 is a decompression unit that decompresses and expands the liquid refrigerant. The evaporator 13 evaporates the refrigerant expanded under reduced pressure by heat exchange between the refrigerant and the blown air.

  Further, on the input side of the air conditioning control device 50, in addition to the sensor group shown in FIG. 2, a discharge temperature sensor (discharge temperature detecting means) that detects the discharge refrigerant temperature Tc of the compressor 31, An evaporator temperature sensor (evaporator temperature detection means) that detects the blown air temperature (evaporator temperature) TE, an intake temperature sensor that detects the temperature Tsi of the refrigerant sucked into the compressor 31, and an engine that has flowed out of the engine EG A sensor group (not shown) such as a cooling water temperature sensor (cooling water temperature detecting means) for detecting the cooling water temperature TW of the cooling water is also connected.

  The evaporator temperature sensor specifically detects the heat exchange fin temperature of the evaporator 13. Of course, the evaporator temperature sensor may detect the temperature of other parts of the evaporator 13 or may directly detect the temperature of the refrigerant itself flowing through the evaporator 13.

  Further, operation signals from various air conditioning operation switches provided on the operation panel 60 disposed near the instrument panel in the front part of the vehicle interior are input to the input side of the air conditioning control device 50. On the operation panel 60, as various air conditioning operation switches, specifically, an operation switch (not shown) of the vehicle air conditioner 1 and on / off of the air conditioner (specifically, on / off of the compressor 31) are provided. Air conditioner switch 60a for switching, auto switch 60b, operation mode switch (not shown), suction port mode switch (not shown) for switching the suction port mode, and outlet mode switch 60c as an instruction input device for switching the outlet mode Further, an air volume setting switch (not shown) of the blower 12, a vehicle interior temperature setting switch (not shown) for setting a target temperature Tset in the vehicle interior by an occupant's operation, and the like are provided. The auto switch 60b is automatic control setting means for setting or canceling automatic control of the vehicle air conditioner 1 by the operation of the passenger.

  In addition, the air conditioning control device 50 is electrically connected to an electro multivision system 70 (hereinafter referred to as an EMV system). The EMV system 70 can control navigation, audio, an air conditioner, and the like using a display on a liquid crystal display. In addition, operation switches of a plurality of devices such as a navigation device, an audio device, and an air conditioner are arranged on a design panel mounted on the front surface of the display of the EMV system 70. The EMV system 70 corresponds to the instruction input device and the presenting means of the present invention.

  The air-conditioning control device 50 is electrically connected to an engine control device 90 that is an engine computer that controls the operation of the engine EG, and the air-conditioning control device 50 and the engine control device 90 are configured to be able to electrically communicate with each other. Has been. Thereby, based on the detection signal or operation signal input into one control apparatus, the other control apparatus can also control the operation | movement of the various apparatuses connected to the output side. For example, the engine EG can be operated by the air conditioning control device 50 outputting an operation request signal for the engine EG to the engine control device 90. Further, when the engine EG is operating for air conditioning, the engine EG can be stopped by the air conditioning control device 50 not outputting an operation request signal for the engine EG.

  The air-conditioning control device 50 and the engine control device 90 are configured such that control means for controlling various control target devices connected to the output side is integrally configured, but controls the operation of each control target device. The configuration (hardware and software) constitutes control means for controlling the operation of each control target device. For example, the structure which controls the action | operation of blower outlet mode door 24a, 25a, 26a among the air-conditioning control apparatuses 50 comprises the blower outlet mode control means which controls switching of blower outlet mode.

  Next, control by the air conditioning control device 50 will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing an example of processing of the air conditioning control device 50. First, when the ignition switch is turned on and DC power is supplied to the air conditioning control device 50, a control program stored in advance in a memory is executed. When the ignition switch is turned on, it is a time when the vehicle enters a travelable state from a parked state by a user operation.

  In step S1, the contents stored in the data processing memory incorporated in the microcomputer inside the air conditioning control device 50 are initialized (initialized), and the process proceeds to step S2. In step S2, the operation signal (switch signal) of the operation panel 60 is read and the process proceeds to step S3. Specific operation signals include a vehicle interior target temperature Tset setting signal set by a vehicle interior temperature setting switch, an auto switch 60b operation signal, an air outlet mode switch 60c operation signal, and the like. Further, the operation signal of the EMV system 70 is also read in step S2.

  Next, in step S3, sensor signals from various sensors are read, and the process proceeds to step S4. In steps S2 and S3, various data are read into the data processing memory. As sensor signals, for example, an inside air temperature (vehicle interior temperature) Tr detected by the inside air sensor 51, an outside air temperature Tam detected by the outside air sensor 52, an amount of solar radiation Ts detected by the solar radiation sensor 53, and a temperature sensor after the evaporator are detected. There are a post-evaporator temperature (Te) and an engine coolant temperature Tw detected by a coolant temperature sensor.

In step S4, the input data is substituted into the following mathematical formula F1 stored in advance to calculate the target blowing temperature TAO, and the process proceeds to step S5.
TAO = Kset * Tset-Kr * Tr-Kam * Tam-Ks * Ts + C (F1)
Here, Tset is a set temperature set by a temperature setting switch, Tr is an inside air temperature, Tam is an outside air temperature, and Ts is a solar radiation amount. Kset, Kr, Kam, and Ks are gains, and C is a correction constant for the whole. And the control value of the actuator of the air mix door 19, the control value of the rotation speed of the electric water pump 42, etc. are calculated from the target blowing temperature TAO and signals from the various sensors.

  In step S5, a process for determining the blower voltage is performed. The blower voltage is a voltage applied to the blower motor 121, and the amount of blown air is changed according to the blower voltage. The blower voltage determination process is a process for determining the blower voltage based on the target blowing temperature TAO and signals from the various sensors and the operation panel 60. As the blower voltage determination process, for example, the same process as the blower voltage determination process described in Patent Document 1 and Japanese Patent Application Laid-Open No. 2014-28532 can be performed.

  Next, in step S6, a suction port mode determination process is performed. The suction port mode determination process is a process of determining the suction port mode based on the target outlet temperature TAO and signals from the various sensors and the operation panel 60. As the suction port mode determination process, for example, the same process as the suction port mode determination process described in JP 2001-130247 A can be performed.

  Next, in step S7, a blower outlet mode determination process for determining a blower outlet for blowing conditioned air into the passenger compartment is performed, and the process proceeds to step S8.

  In the present embodiment, the control process shown in FIG. 4 is performed in addition to the control process of the main routine of FIG. The control process shown in FIG. 4 is executed as a subroutine.

  In the control process of the subroutine shown in FIG. 4, the outlet mode to be executed is set based on various information, the set outlet mode flag is set to 1, and the not set outlet mode flag is set to 0. For example, when the face mode is set, the face mode flag is set to 1, and the flags of other outlet modes that are not set are set to 0.

  And in the control process of the main routine of step S7 of FIG. 3, the mode in which the flag is 1 is determined as the blower outlet mode. Details of the air outlet mode determination process will be described later.

  Next, in step S8, a compressor rotation speed determination process is performed. The compressor rotational speed determination process is a process for determining the rotational speed of the compressor based on the target evaporator temperature TEO or the like. As the compressor rotation speed determination process, for example, the same process as the compressor rotation speed determination process described in Patent Document 1 and Japanese Patent Laid-Open No. 2014-28532 can be performed.

  Next, in step S9, a PTC operation number determination process is performed. The PTC operation number determination process is a process of determining the operation number of the PTC heater 15 (also simply referred to as PTC) constituting the electric heater. For example, similarly to the processing described in Patent Document 1 and Japanese Patent Application Laid-Open No. 2014-28532, the number of operating PTC heaters 15 is determined according to a previously stored control map, and is increased as the engine coolant temperature Tw is lower.

  Next, in step S10, a required water temperature determination process is performed. The required water temperature determination process is based on the target outlet temperature TAO or the like in order to use the engine coolant as a heat source such as heating and anti-fogging, as in the processes described in Patent Document 1 and Japanese Patent Application Laid-Open No. 2014-28532, for example. Determine the required coolant temperature of the engine coolant. Then, based on the required coolant temperature of the engine cooling water, it is determined whether an engine-on request for requesting the engine control device 90 to start the engine EG is required.

  Next, in step S11, an electric water pump operation determination process is performed. The electric water pump operation determination process is a process for determining on / off of the electric water pump 42 (see FIG. 1) based on the engine coolant temperature Tw and the like. As the electric water pump operation determination process, for example, the same process as the electric water pump operation determination process described in Patent Document 1 and Japanese Patent Application Laid-Open No. 2014-28532 can be performed.

  Next, in step S12, the target evaporator temperature TEO is determined. This target evaporator temperature TEO is a target temperature of the evaporator temperature TE. The target evaporator temperature TEO determination process is a process of determining the target evaporator temperature TEO based on the target outlet temperature TAO determined in step S4 (see FIG. 3). As this process, for example, a process similar to the process described in JP 2014-28532 A can be performed.

  Next, in step S13, control signals are output to the various actuators, the engine control device 90, and the like so that the control states calculated or determined in the above steps S4 to S12 are obtained. Further, a control signal is output to the operation panel 60, and the display on the display unit 60d of the operation panel 60 is switched.

  Next, in step S14, the process waits for the control period T, and when it is determined that the control period T has elapsed, the process returns to step S2. In the present embodiment, the control cycle T is 250 ms. This is because the air conditioning control in the passenger compartment does not adversely affect the controllability even if the control period is slower than the engine control or the like. As a result, it is possible to suppress a communication amount for air conditioning control in the vehicle and sufficiently secure a communication amount of a control system that needs to perform high-speed control such as engine control.

  Next, the air outlet mode determination process in step S7 will be described. As shown in FIG. 4, in step S701, it is determined based on the window clearing mode flag set in step S702 whether the window clearing mode is being executed.

  Note that the state in which the defroster mode or the foot defroster mode is executed based on the passenger's window clearing instruction corresponds to the execution of the window clearing mode. The window clearing mode flag is 1 during execution of the window clearing mode. Incidentally, the window clearing mode flag is 0 when it is initialized in step S1.

  If it is determined in step S701 that the window clearing mode is not being executed, the process proceeds to step S702. In step S702, it is determined whether or not there has been an instruction to clear the window of the passenger.

  Specifically, when the defroster mode or the foot defroster mode is selected by the air outlet mode switch 60c or the operation switch of the EMV system 70, it is determined that the passenger has instructed to clear the window. In addition, a voice recognition device (not shown) as an instruction input device may be provided, and a window clearing instruction may be given by a passenger's voice.

  If it is determined in step S702 that the passenger has instructed to clear the window, the process proceeds to step S703. In step S703, the display of the EMV system 70 indicates that only window clearing is performed in the defroster mode, window clearing and heating are performed in the foot defroster mode, and that either the defroster mode or the foot defroster mode can be selected. For example, it is displayed for 10 seconds and presented to the passenger. Thereby, the occupant can be informed of the meaning of proper use of the defroster mode and the foot defroster mode. Note that a voice generation device (not shown) as a presentation unit may be provided, and presentation may be performed by voice of the voice generation device.

  The process proceeds from step S703 to step S704, and in step S704, it is determined which one of the defroster mode and the foot defroster mode is selected based on the switch operation on the display of the EMV system 70.

  Specifically, during the process of step S703, the occupant touched the first selection switch 703a on the display of the EMV system 70 where “both window clearing and heating (F / D)” are displayed. In this case, it is determined in step S704 that the foot defroster mode has been selected, and the process proceeds to step S705. In step S705, the foot defroster mode is set as the air outlet mode, the foot defroster mode flag is set to 1, and the flags of the other air outlet modes are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the foot defroster mode whose flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is set so that the foot defroster mode is executed. In response, a control signal is output. As a result, when the occupant selects the foot defroster mode in step S703, air is blown out from both the foot blowout port 25 and the defroster blowout port 26, so that the burning of the face and the coldness of the feet are minimized. Antifogging control is performed.

  On the other hand, when the occupant touches the second selection switch 703b of the part displayed as “Window clearing only (DEF)” on the display of the EMV system 70 during the process of step S703, and during the process of step S703 If the occupant does not touch any of the switches 703a and 703b on the display of the EMV system 70, it is determined in step S704 that the defroster mode has been selected, and the process proceeds to step S706. In step S706, the defroster mode is set as the outlet mode, the defroster mode flag is set to 1, and the other outlet mode flags are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the defroster mode in which the flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is operated so that the defroster mode is executed. Output a control signal. Thereby, when the passenger | crew selects defroster mode in step S703, since air blows off from the defroster blower outlet 26, high anti-fogging performance is obtained.

  If it is determined in step S701 described above that the window clearing mode is being executed, the process proceeds to step S707. In step S707, it is determined whether or not there is an instruction to end the window clearing by the passenger.

  Specifically, when the face mode, the bi-level mode, the foot mode, or the air outlet auto control mode is selected by the operation switch of the air outlet mode switch 60c or the EMV system 70, an instruction to end the window clearing of the occupant is given. It is determined that there was. Note that a voice recognition device may be provided to instruct the end of window clearing by the voice of the passenger.

  If it is determined in step S707 that there has been no instruction to end the window clearing by the passenger, the process returns. In this case, the air outlet mode set in step S705 or step S706 is continuously executed.

  On the other hand, if it is determined in step S707 that the passenger has instructed the window clearing to end, the process proceeds to step S708. In step S708, it is determined whether or not the air outlet auto control mode is selected. Specifically, when the blower outlet auto control mode is selected by the blower outlet mode switch 60c or the operation switch of the EMV system 70, it is determined that the blower outlet auto control mode is selected.

  If it is determined in step S708 that the air outlet auto control mode is selected, the process proceeds to step S709. In step S709, one of the outlet (FACE), bi-level (B / L), and foot (FOOT) outlet modes is set from the map of FIG. 4 based on the target outlet temperature TAO. When it is determined that there is a possibility of window fogging of the vehicle window glass based on the detection signal from each sensor, the air outlet mode is set to the foot differential (F / D). For example, when the vehicle is heated during traveling in a cold region where the outside air temperature Tam is extremely low, it is determined that there is a possibility that the vehicle window glass is fogged. Then, the air outlet mode flag set in step S708 is set to 1, and the other air outlet mode flags are set to 0.

  On the other hand, when it determines with the blower outlet auto control mode not having been selected in step S708, it progresses to step S710. In step S710, the air outlet mode selected by the occupant is set using the air outlet mode switch 60c or the operation switch of the EMV system 70. Then, the air outlet mode flag set in step S710 is set to 1, and the other air outlet mode flags are set to 0.

  If it is determined in step S702 described above that there has been no instruction for the passenger to clear the window, the process proceeds to step S708. Then, depending on the determination result of step S708, the process of step S709 or step S710 is performed.

  According to this embodiment, even if the occupant is not familiar with the operation of the air conditioner, the anti-fogging control that minimizes the burning of the face and the cold of the feet is ensured in situations where high anti-fogging performance is not required. It can be carried out.

(Second Embodiment)
A second embodiment of the present invention will be described. In the present embodiment, differences from the first embodiment will be mainly described.

  As shown in FIG. 5, if it is determined in step S702 that an occupant's window clearing instruction has been given, the process proceeds to step S721. In step S721, the defroster mode is set as the outlet mode, the defroster mode flag is set to 1, and the other outlet mode flags are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the defroster mode in which the flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is operated so that the defroster mode is executed. Output a control signal.

  As a result, when it is determined in step S702 that an occupant's window clearing instruction has been given, the defroster mode is immediately executed, and first the window clearing requirement can be satisfied and the field of view can be secured.

  Proceeding from step S721 to step S722, in step S722, if the defroster mode is continued, only the window clearing is performed, window changing and heating is performed when the mode is changed to the foot defroster mode, and the defroster mode and the foot defroster mode For example, it is displayed on the display of the EMV system 70 for 10 seconds to indicate that either one can be selected. Thereby, the occupant can be informed of the meaning of proper use of the defroster mode and the foot defroster mode. In addition, a voice generation device may be provided and the presentation may be performed by the voice of the voice generation device.

  Proceeding from step S722 to step S723, based on the switch operation on the display of the EMV system 70, it is determined which of the continuation of the defroster mode and the change to the foot defroster mode has been selected.

  Specifically, during the process of step S722, the occupant enters the first selection switch 722a on the display of the EMV system 70 where “both window clearing and heating (change to F / D)” is displayed. If touched, it is determined in step S723 that the change to the foot defroster mode has been selected, and the process proceeds to step S724. In step S724, the foot defroster mode is set as the outlet mode, the foot defroster mode flag is set to 1, and the other outlet mode flags are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the foot defroster mode whose flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is set so that the foot defroster mode is executed. In response, a control signal is output. As a result, when the occupant selects to change to the foot defroster mode in step S722, air is blown from both the foot blower outlet 25 and the defroster blower outlet 26, so that the hot flash on the face and the coldness of the feet are minimized. Suppressed anti-fogging control is performed.

  On the other hand, during the process of step S722, when the occupant touches the second selection switch 722b on the display of the EMV system 70 where “only window clearing (continuation of DEF)” is displayed, and the process of step S722 If the occupant does not touch any of the switches 722a and 722b on the display of the EMV system 70, it is determined in step S723 that the defroster mode continuation is selected, and the process proceeds to step S725.

  In step S725, the defroster mode is continued without changing the air outlet mode flag. Thereby, high anti-fogging performance is obtained continuously.

  According to the present embodiment, even if the occupant is not familiar with the operation of the air conditioner, first, after satisfying the demand for window clearing, under the circumstances where high anti-fogging performance is not required, the hot flash of the face and the coldness of the feet It is possible to reliably perform the antifogging control that is minimized.

(Third embodiment)
A third embodiment of the present invention will be described. In the present embodiment, differences from the first embodiment will be mainly described.

  As shown in FIG. 6, if it is determined in step S702 that there is an instruction to clear the window of the passenger, the process proceeds to step S731. In step S731 as the travel determination means, it is determined whether or not the vehicle is traveling based on the vehicle speed signal from the engine control device 90.

  If it is determined in step S731 that the vehicle is traveling, the process proceeds to step S732. In step S732, the defroster mode is set as the outlet mode, the defroster mode flag is set to 1, and the other outlet mode flags are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the defroster mode in which the flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is operated so that the defroster mode is executed. Output a control signal.

  Thereby, when it determines with driving | running | working vehicle in step S731, a defroster mode can be performed immediately and the request | requirement of window clearing can be satisfy | filled first and a visual field can be ensured.

  On the other hand, if it is determined in step S731 that the vehicle is not traveling (that is, the vehicle is stopped), the process proceeds to step S703.

  According to the present embodiment, even if the occupant is not familiar with the operation of the air conditioner, in the scene related to safety (specifically, the situation where priority is given to ensuring visibility over comfort as in driving) In a situation where high anti-fogging performance is not required while satisfying the demand for clearing, anti-fogging control can be reliably performed while minimizing hot flashes and cold feet.

(Fourth embodiment)
A fourth embodiment of the present invention will be described. Only the parts different from the first embodiment will be described below.

  As shown in FIG. 7, if it is determined in step S702 that there is an instruction to clear the window of the passenger, the process proceeds to step S741. In step S741 as travel determination means, it is determined based on the vehicle speed signal from the engine control device 90 whether or not the vehicle is traveling.

  If it is determined in step S741 that the vehicle is traveling, the process proceeds to step S742. In step S742, the defroster mode is set as the outlet mode, the defroster mode flag is set to 1, and the other outlet mode flags are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the defroster mode in which the flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is operated so that the defroster mode is executed. Output a control signal.

  Accordingly, when it is determined in step S741 that the vehicle is traveling, the defroster mode is immediately executed, and the view can be secured by first satisfying the demand for window clearing.

  After step S742, the process proceeds to step S743. In step S743, it is determined whether or not there is an instruction to end the window clearing by the passenger. Specifically, when the face mode, the bi-level mode, the foot mode, or the air outlet auto control mode is selected by the operation switch of the air outlet mode switch 60c or the EMV system 70, an instruction to end the window clearing of the occupant is given. It is determined that there was.

  If it is determined in step S743 that there has been an instruction to end the window clearing by the occupant, the process proceeds to step S708.

  On the other hand, if it is determined in step S743 that there has been no instruction to end the window clearing by the passenger, the process proceeds to step S741. In step S741, the processes in steps S741 to S743 are repeated until it is determined that the vehicle is not traveling (that is, the vehicle is stopped).

  While it is determined that the vehicle is not traveling in step S741 while the processes of steps S741 to S743 are repeated, and when the process proceeds from step S702 to step S741, it is determined that the vehicle is not traveling in step S741. In the case, the process proceeds to step S703.

  According to the present embodiment, even if the occupant is not familiar with the operation of the air conditioner, in the scene related to safety (specifically, the situation where priority is given to ensuring visibility over comfort as in driving) In a situation where high anti-fogging performance is not required while satisfying the demand for clearing, anti-fogging control can be reliably performed while minimizing hot flashes and cold feet.

(Fifth embodiment)
A fifth embodiment of the present invention will be described. Only the parts different from the first embodiment will be described below.

  As shown in FIG. 8, if it is determined in step S702 that an occupant's window clearing instruction has been given, the process proceeds to step S751. In step S751, it is determined whether or not the humidity RHW in the vicinity of the vehicle front window glass 74 (hereinafter referred to as “window vicinity humidity”) is 95% or more. Note that the near-window humidity RHW can be detected by a humidity sensor (not shown) as a humidity detecting means arranged in the vicinity of the vehicle front window glass 74. Moreover, 95% is a threshold value estimated that the vehicle front window glass 74 is fogged.

  If it is determined in step S751 that the near window humidity RHW is 95% or more, the process proceeds to step S752. In step S752, the display of the EMV system 70 indicates that only window clearing is performed in the defroster mode, window clearing and heating are performed in the foot defroster mode, and that either the defroster mode or the foot defroster mode can be selected. For example, it is displayed for 10 seconds and presented to the passenger.

  In addition, since it is estimated that the vehicle front window glass 74 is fogged when the near-window humidity RHW is 95% or more, in step S752, the defroster is recommended together with the reason for recommendation (that is, the environment in which the vehicle front window glass 74 is easily fogged). The recommendation of the mode is displayed on the display of the EMV system 70 and presented to the passenger.

  Accordingly, the occupant can be informed of the meaning of properly using the defroster mode and the foot defroster mode, and the defroster mode can be selected as much as possible for the occupant to ensure visibility.

  Proceeding from step S752 to step S753, in step S753, it is determined which one of the defroster mode and the foot defroster mode is selected based on the switch operation on the display of the EMV system 70.

  Specifically, during the process of step S752, the occupant touched the first selection switch 752a on the display of the EMV system 70 where “both window clearing and heating (F / D)” are displayed. In this case, it is determined in step S754 that the foot defroster mode has been selected, and the process proceeds to step S705.

  On the other hand, when the occupant touches the second selection switch 752b of the part displayed as “Window clearing only (DEF)” on the display of the EMV system 70 during the process of step S752, and during the process of step S752. If the occupant does not touch any of the switches 752a and 752b on the display of the EMV system 70, it is determined in step S753 that the defroster mode has been selected, and the process proceeds to step S706.

  If it is determined in step S751 that the near-window humidity RHW is less than 95%, the process proceeds to step S754. In step S754, the display of the EMV system 70 indicates that only window clearing is performed in the defroster mode, window clearing and heating are performed in the foot defroster mode, and that either the defroster mode or the foot defroster mode can be selected. For example, it is displayed for 10 seconds and presented to the passenger.

  Further, when the near-window humidity RHW is less than 95%, it is estimated that the vehicle front window glass 74 is not fogged or slightly cloudy. Therefore, in step S754, the reason for recommendation (that is, the environment where the vehicle front window glass 74 is difficult to fog). And recommending the foot defroster mode is displayed on the display of the EMV system 70 and presented to the passenger.

  As a result, the occupant can be informed of the meaning of using the defroster mode and the foot defroster mode properly, and the foot defroster mode can be selected to become an occupant, and anti-fogging control that minimizes the burning of the face and the coldness of the feet is possible. It can be carried out.

  The process proceeds from step S754 to step S753, and in step S753, it is determined which one of the defroster mode and the foot defroster mode is selected based on the switch operation on the display of the EMV system 70.

  Specifically, during the process of step S754, the occupant touched the first selection switch 754a on the display of the EMV system 70 where “both window clearing and heating (F / D)” are displayed. In this case, it is determined in step S753 that the foot defroster mode has been selected, and the process proceeds to step S705.

  On the other hand, during the process of step S754, when the occupant touches the second selection switch 754b on the display of the EMV system 70 where “Window clearing only (DEF)” is displayed, and during the process of step S754 If the occupant does not touch any of the switches 754a and 754b on the display of the EMV system 70, it is determined in step S753 that the defroster mode has been selected, and the process proceeds to step S706.

  According to this embodiment, even if the passenger is not familiar with the operation of the air conditioner, the defroster mode is recommended for safety-related scenes (specifically, an environment in which the window glass is estimated to be fogged). In a situation where high visibility is not required and high anti-fogging performance is not required, foot defroster mode is recommended to ensure anti-fogging control with minimal hot flashes and cold feet. Can do.

(Sixth embodiment)
A sixth embodiment of the present invention will be described. Only the parts different from the first embodiment will be described below.

  As shown in FIG. 9, if it is determined in step S702 that there is an instruction to clear the window of the passenger, the process proceeds to step S761. In step S761 as travel determination means, it is determined whether the vehicle is traveling based on a vehicle speed signal from the engine control device 90.

  If it is determined in step S761 that the vehicle is traveling, the process proceeds to step S762. In step S762, the defroster mode is set as the outlet mode, the defroster mode flag is set to 1, and the other outlet mode flags are set to 0.

  Then, in the main routine of step S7 in FIG. 3, the defroster mode in which the flag is 1 is determined as the outlet mode, and in step S13 of FIG. 3, the electric actuator 64 is operated so that the defroster mode is executed. Output a control signal.

  Accordingly, when it is determined in step S761 that the vehicle is traveling, the defroster mode is immediately executed, and the field of view can be secured by first satisfying the desire for window clearing.

  After step S762, the process proceeds to step S763. In step S763, it is determined whether or not there is an instruction to end the window clearing by the passenger. Specifically, when the face mode, the bi-level mode, the foot mode, or the air outlet auto control mode is selected by the operation switch of the air outlet mode switch 60c or the EMV system 70, an instruction to end the window clearing of the occupant is given. It is determined that there was.

  If it is determined in step S763 that the passenger has instructed the window clearing to end, the process proceeds to step S708.

  On the other hand, if it is determined in step S763 that there has been no instruction for the passenger to clear the window, the process proceeds to step S761. In step S761, the processes in steps S761 to S763 are repeated until it is determined that the vehicle is not traveling (that is, the vehicle is stopped).

  While it is determined that the vehicle is not traveling in step S761 while the processes of steps S761 to S763 are repeated, and when the process proceeds from step S702 to step S761, it is determined that the vehicle is not traveling in step S761. In the case, the process proceeds to step S764.

  In step S764, it is determined whether the near-window humidity RHW is 95% or more. Note that the near-window humidity RHW can be detected by a humidity sensor (not shown) as a humidity detecting means arranged in the vicinity of the vehicle front window glass 74. Moreover, 95% is a threshold value estimated that the vehicle front window glass 74 is fogged.

  If it is determined in step S764 that the near-window humidity RHW is 95% or more, the process proceeds to step S765. In step S765, the display of the EMV system 70 indicates that only window clearing is performed in the defroster mode, window clearing and heating are performed in the foot defroster mode, and that either the defroster mode or the foot defroster mode can be selected. For example, it is displayed for 10 seconds and presented to the passenger.

  In addition, since it is estimated that the vehicle front window glass 74 is fogged when the near-window humidity RHW is 95% or more, in step S765, the defroster is displayed together with a recommendation reason (that is, the environment in which the vehicle front window glass 74 is easily fogged). The recommendation of the mode is displayed on the display of the EMV system 70 and presented to the passenger.

  Accordingly, the occupant can be informed of the meaning of properly using the defroster mode and the foot defroster mode, and the defroster mode can be selected as much as possible for the occupant to ensure visibility.

  Proceeding from step S765 to step S766, based on the switch operation on the display of the EMV system 70, it is determined which one of the defroster mode and the foot defroster mode has been selected.

  Specifically, during the process of step S765, the occupant touched the first selection switch 765a on the display of the EMV system 70 where “Both window clearing and heating (F / D)” are displayed. In this case, it is determined in step S766 that the foot defroster mode has been selected, and the process proceeds to step S705.

  On the other hand, during the process of step S765, when the occupant touches the second selection switch 765b on the display of the EMV system 70 where “Window clearing only (DEF)” is displayed, and during the process of step S765 If the occupant does not touch any of the switches 765a and 765b on the display of the EMV system 70, it is determined in step S766 that the defroster mode is selected, and the process proceeds to step S706.

  If it is determined in step S764 that the near-window humidity RHW is less than 95%, the process proceeds to step S767. In step S767, the display of the EMV system 70 indicates that only window clearing is performed in the defroster mode, window clearing and heating are performed in the foot defroster mode, and that either the defroster mode or the foot defroster mode can be selected. For example, it is displayed for 10 seconds and presented to the passenger.

  Further, if the near-window humidity RHW is less than 95%, it is estimated that the vehicle front window glass 74 is not fogged or slightly cloudy. Therefore, in step S767, the reason for recommendation (that is, the environment where the vehicle front window glass 74 is difficult to fog). And recommending the foot defroster mode is displayed on the display of the EMV system 70 and presented to the passenger.

  As a result, the occupant can be informed of the meaning of using the defroster mode and the foot defroster mode properly, and the foot defroster mode can be selected to become an occupant, and anti-fogging control that minimizes the burning of the face and the coldness of the feet is possible. It can be carried out.

  Proceeding from step S767 to step S766, it is determined in step S766 which one of the defroster mode and the foot defroster mode has been selected based on the switch operation on the display of the EMV system 70.

  Specifically, during the process of step S767, the occupant touched the first selection switch 767a on the display of the EMV system 70 where “Both window clearing and heating (F / D)” are displayed. In this case, it is determined in step S766 that the foot defroster mode has been selected, and the process proceeds to step S705.

  On the other hand, during the process of step S767, when the occupant touches the second selection switch 767b on the display of the EMV system 70 where “window clearing only (DEF)” is displayed, and during the process of step S767. If the occupant does not touch any of the switches 767a and 767b on the display of the EMV system 70, it is determined in step S766 that the defroster mode is selected, and the process proceeds to step S706.

  According to the present embodiment, even if the occupant is not familiar with the operation of the air conditioner, in the scene related to safety (specifically, the situation where priority is given to ensuring visibility over comfort as in driving) In a situation where high anti-fogging performance is not required while satisfying the demand for clearing, anti-fogging control can be reliably performed while minimizing hot flashes and cold feet.
