Description

  The present invention relates to a vehicle ventilation system.

JP 2006-7928 A

  When the vehicle is parked outdoors for a long time under the hot weather in midsummer, the inside of the vehicle may become hot, and it may be hesitant to enter the vehicle instead of driving. For this reason, for example, there is a disclosure of a technique for cooling the interior of the vehicle by ventilating the interior of the vehicle using a technique such as Patent Document 1. In Patent Document 1, a bypass channel that communicates between an indoor air channel and an outdoor air channel is provided, and indoor air is sucked into the bypass channel by sucking the indoor air from the indoor air channel by an electric blower. The air is discharged from the outdoor air flow path to the outside of the vehicle.

  However, as in Patent Document 1, it is costly to newly provide ventilation equipment such as a bypass passage and a blower, and there is a problem of securing a space for arranging them. In addition, there is a simple method to keep the window slightly open in order to prevent the temperature inside the parked vehicle from getting too high, but this will cause a problem of crime prevention. Conversely, if the window is slightly opened, High temperature cannot be prevented. There is also a method of operating the air conditioner in advance by starting a remote engine such as a remote control engine starter, but it is extremely inefficient to cool the interior of the vehicle in a hot state only with the air conditioner, resulting in deterioration of fuel consumption and battery It becomes a factor of the rise.

  An object of the present invention is to provide a vehicle ventilation system that can efficiently and promptly cool the interior of a vehicle when the interior of the vehicle becomes hot, such as when the vehicle is parked outdoors, and that is free from crime prevention problems. It is to provide at low cost.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the first of the vehicle ventilation systems of the present invention is:
A plurality of power windows provided in the vehicle;
A ventilation mode selection input means for accepting a ventilation mode selection input operation by the user;
Engine start detection means for detecting engine start of the vehicle;
Ventilation control means for controlling ventilation opening / closing to control the plurality of power windows to have a predetermined open mode as a ventilation mode when the engine start is detected and the ventilation mode selection input operation is received; ,
The ventilation control means is characterized in that, in the ventilation mode, a pair of power windows located on different sides in the vehicle width direction are simultaneously opened .

  According to the present invention, the interior of the vehicle can be efficiently cooled by the opening and closing operation of the power window accompanying the engine start. Compared with the case of using an inefficient cooling method in which the inside of a vehicle in a high temperature state is cooled only by the air conditioner, fuel saving can be achieved. In addition, since the system uses a power window already mounted on a general vehicle, there is an advantage that it can be realized at a low cost. Furthermore, according to the present invention, since ventilation by the power window can be started at the user's judgment, the power window is not opened when the user is absent, and there is no problem in crime prevention. Furthermore, since the driver can start the ventilation opening and closing drive of the power window at the discretion of the driver, the user is surprised and confused by the sudden driving of the power window.

  The ventilation control means can simultaneously open a pair of power windows positioned on different sides in the vehicle width direction in the ventilation mode. According to this configuration, during ventilation, the air in the vehicle can be moved from the left and right windows of the vehicle to the window, so that the air passes laterally through the vehicle, and the inside of the vehicle can be efficiently ventilated. . Further, the ventilation control means can open the power window pairs at different opening degrees in the ventilation mode. According to this configuration, based on Bernoulli's theorem, an airflow flows from a window having a small opening to a window having a large opening, so that the inside of the vehicle can be efficiently ventilated. In other words, the flow of air in the passenger compartment is controlled so that the outside air is taken in at high speed from the window with a small opening, and the high-temperature air stagnating in the vehicle due to the taken-in outside air is discharged from the window with a large opening. As a result, the interior of the vehicle can be efficiently ventilated.

  The ventilation control means can open a pair of power windows in different positions in the vehicle width direction and the vehicle length direction in the ventilation mode. Thereby, since the flow of an airflow can be made in the diagonal direction different from a vehicle width direction and a vehicle length direction, the air in a vehicle can be ventilated efficiently. In addition, by opening the pair of power windows while closing the remaining power windows, it is possible to reliably create an airflow in the oblique direction and perform ventilation. Specifically, the vehicle is a passenger car, and the pair of power windows that are opened in the ventilation mode are the front seat power window on the first side and the rear seat power on the second side in the vehicle width direction. Can be defined as a window. Thereby, the flow of the air from the window arrange | positioned diagonally in the vehicle to a window is formed, and ventilation can be performed efficiently.

In order to solve the above problems, the second of the vehicle ventilation systems of the present invention is:
A plurality of power windows provided in the vehicle;
A ventilation mode selection input means for accepting a ventilation mode selection input operation by the user;
Engine start detection means for detecting engine start of the vehicle;
Ventilation control means for controlling ventilation opening / closing to control the plurality of power windows to have a predetermined open mode as a ventilation mode when the engine start is detected and the ventilation mode selection input operation is received; ,
Comprising a and ventilation control means, in the ventilation mode, and executes sequentially switching a plurality of driving states in which the open form are different from each other of the plurality of power windows.
According to this configuration, the open state of the power window is switched, and airflow is formed in a plurality of directions, so that the inside of the vehicle can be ventilated more efficiently. Specifically, in the ventilation mode, the ventilation control means executes the first mode in which the first-side front seat power window and the second-side rear seat power window in the vehicle width direction are opened. After that, it is possible to execute the second mode in which the first-side rear seat power window in the vehicle width direction and the second-side front seat power window are opened. Thereby, since the flow of the air which flows through the inside of a vehicle switches between a 1st diagonal direction and a 2nd diagonal direction, the inside of a vehicle can be ventilated more efficiently.

  The in-vehicle air conditioner that blows out the air-conditioned airflow from the air outlet provided in the vehicle and the ventilation control means can execute the blowout of the air-conditioned airflow by the in-vehicle air conditioner together with the ventilation opening / closing drive of the power window as the ventilation operation control. According to this configuration, the air flow generated by the opening of the power window can be assisted by the air-conditioning airflow blown from the on-vehicle air conditioner (on-vehicle air conditioner), so that the inside of the vehicle can be ventilated more efficiently.

  In addition, the vehicle is a passenger car, and the pair of power windows that are opened in the ventilation mode are a first-side front seat power window and a second-side rear seat power window in the vehicle width direction. In this case, it is provided with a blowing direction control means for controlling the blowing direction of the air-conditioning airflow by the in-vehicle air conditioner so as to be the direction from one power window that is open in the vehicle width direction to the other power window. Can be configured. According to this configuration, the air-conditioning air flow of the in-vehicle air conditioner (on-vehicle air conditioner) can be blown out in a form corresponding to the open state of the power window so that the air flow generated by the opening of the power window is assisted. The interior of the car can be ventilated more efficiently with the assistance of airflow.

  In addition, when the ventilation control means opens the pair of power windows at different opening degrees in the ventilation mode, the opening degree indicates the direction in which the air-conditioning air current is blown from the outlet of the in-vehicle air conditioner. A blow direction control means for controlling the direction from the small power window to the power window where the opening degree becomes large can be provided. According to this configuration, the air flow in the vehicle interior that flows from the window with a small opening toward the window with a large opening can be assisted by the air-conditioned airflow, so that the inside of the vehicle can be ventilated more efficiently.

  The present invention can be configured to include usage guidance information output means for outputting ventilation mode usage guidance information by the ventilation mode selection input means by visual information, audio information, or a combination thereof. Thereby, the user can easily use the ventilation function of the present invention.

  The present invention can include an in-vehicle temperature detecting means for detecting an in-vehicle temperature, and at this time, the ventilation control means is opened in the ventilation mode when the detected in-vehicle temperature falls below a predetermined temperature. It can be configured to close the power window. According to this configuration, since ventilation is automatically terminated, ventilation that bothers the driver's hand can be terminated before the driver feels cold.

  On the other hand, the present invention can include an in-vehicle temperature detecting means for detecting the in-vehicle temperature and an out-of-vehicle temperature detecting means for detecting the outside temperature. At this time, the ventilation control means has the detected in-vehicle temperature and out-of-vehicle temperature. When the temperature difference between and becomes less than a predetermined value, the ventilation operation control can be suppressed. Even in this configuration, since the ventilation is automatically terminated, the ventilation that bothers the driver's hand can be terminated before the driver feels cold. Moreover, since ventilation is continued until the vehicle interior temperature and the vehicle exterior temperature approach, useless use of the air conditioner can be suppressed.

In order to solve the above problems, the third aspect of the vehicle ventilation system of the present invention is:
A plurality of power windows provided in the vehicle;
Engine start detection means for detecting engine start of the vehicle;
A ventilation mode selection input means for accepting a ventilation mode selection input operation by the user;
Ventilation control means for controlling ventilation opening / closing to control the plurality of power windows to have a predetermined open mode as a ventilation mode when the engine start is detected and the ventilation mode selection input operation is received; ,
And the ventilation control means can include a ventilation operation interruption means for interrupting the ventilation operation when a manual operation for manually opening and closing the power window is performed during the ventilation operation control.
According to this configuration, for example, when the user opens and closes the power window with an intention different from ventilation, the operation is performed with priority, so the user can freely open the power window without being restricted by the ventilation operation. It can be opened and closed and is convenient.

  In addition, the present invention can be provided with weather information acquisition means for acquiring weather information reflecting the weather around the vehicle. At this time, the ventilation control means is a ventilation operation for suppressing the ventilation operation based on the acquired weather information. It can have a suppressing means. According to this configuration, for example, when rain is detected by a raindrop sensor (rainfall state acquisition means), or when the current precipitation probability at the current position exceeds a predetermined probability from the weather forecast, rain or snow falls. In such a situation, the power window for ventilation can be determined not to be opened or closed, or the opening degree of the power window for ventilation can be determined to be smaller than usual.

A plurality of power windows provided in the vehicle;
Engine start detection means for detecting engine start of the vehicle;
A ventilation mode selection input means for accepting a ventilation mode selection input operation by the user;

Odor presence information acquisition means for acquiring odor presence information reflecting the state of presence of odor around the vehicle;
Based on the acquired malodor present information, can be configured with a stench warning means for warning of the presence of the malodor, the.
According to this configuration, if there is a bad odor before the opening / closing operation of the power window for ventilation when the surrounding area is smelly or a point where it is expected to be smelly, this can be notified to the user. The power window cannot be opened and closed without the user's permission.

  In the vehicle ventilation system 1 of the present embodiment, the air conditioner ECU 100 performs ventilation opening / closing drive control so that a plurality of power windows are opened in advance as ventilation modes in response to detection of engine start by the ignition switch 440. Execute. Specifically, this ventilation opening / closing drive control is executed by the CPU executing a ventilation processing program stored in a memory (for example, a non-volatile memory) of the air conditioner ECU 100. 5, 6, 7, and 8 are flowcharts showing the flow of the ventilation opening / closing drive control process, which will be described below.

  In S <b> 1 of FIG. 5, an engine start trigger signal input to the ignition switch 440 is acquired from the engine ECU 400. Then, in the engine start state, the air conditioner ECU 100 reads the operation state of the IVA switch 11d at the time of the previous engine stop stored in its non-volatile memory, and when the IVA switch 11d is ON, S2 Proceed to Alternatively, when the user performs a ventilation mode selection input operation to the IVA switch 11d within a predetermined time T1 (for example, 60 seconds) from the detection of engine start, the process proceeds to S2. If there is no operation to the IVA switch 11d within the predetermined time T1, the process proceeds to S5, and the air conditioner ECU 100 starts normal control of the air conditioner.

  If the IVA switch 11d is turned on in S2, the process proceeds to S3. In S3, output of the ventilation mode usage guidance information by visual information, audio information, or a combination thereof is started. In the present embodiment, the guidance for ventilation operation is started by displaying on the display screen of the display device 330 connected to the navigation device 300, and the guidance for ventilation operation by voice output from the voice output device 340 is also started. . When S3 ends, the process proceeds to S11 in FIG.

  In S11 of FIG. 6, a display screen 31 (referred to as screen 1 in FIG. 6) shown in FIG. 9 is displayed as a guidance display for ventilation operation. Subsequently, in S12, it is determined whether or not the touch switch 31a is operated among the touch switches 31a and 31b displayed on the display screen 31 for selecting ventilation start (ventilation start) and ventilation stop. In addition to the touch switches 31a and 31b, the display screen 31 also displays ventilation direction information 37 indicating how air flows when ventilation start is selected in the same screen. In the ventilation direction information 37, a power window that is in an open state and a power window that is in a closed state are displayed in an identifiable manner. In S11, as the display screen 31 is displayed, the open / close state of each power window during ventilation, the direction of air flow during ventilation, and explanation of the touch switches 31a and 31b are performed (ventilation operation). And guidance for ventilation operation).

  In S12, if the ventilation start touch switch 31a is not operated, the process proceeds to S20. In S20, it is determined whether or not the touch switch 31b for stopping ventilation is operated. When the touch switch 31b is operated, the process proceeds to S22, and the air conditioner ECU 100 starts normal control of the air conditioner. When the touch switch 31b is not operated, the process proceeds to S21, and it is determined whether or not a predetermined time T2 (for example, 30 seconds) has elapsed since the engine start was detected. If it has not elapsed, the process returns to S4, and if it has elapsed, the process proceeds to S22, where the air conditioner ECU 100 starts normal control of the air conditioner.

  On the other hand, if it is determined in S12 that the ventilation start touch switch 31a has been operated, the process proceeds to S13. In S <b> 13, the voice output device 340 outputs a voice to the effect that the power window of the left front seat (passenger seat) is opened, and then outputs an open drive command for the power window to the corresponding window drive unit 222. As a result, the power window of the left front seat (passenger seat) is opened. Subsequently, in S14, the voice output device 340 outputs a voice to the effect that the power window for the right rear seat is opened, and then outputs an open drive command for the power window to the corresponding window drive unit 224. As a result, the power window of the right rear seat is opened.

  That is, when S14 ends, a ventilation mode is set in which a pair of power windows located on different sides in the vehicle width direction are simultaneously opened. Furthermore, in this ventilation mode, a pair of power windows at different positions in the vehicle width direction and the vehicle length direction are open, and the remaining power windows are closed.

  However, in this ventilation mode, the pair of power windows that are in the open state are open at different opening degrees. That is, in this embodiment, the open state of the power window of the right rear seat that was opened in S14 is more than the open state of the power window of the left front seat (passenger seat) that was opened in S13. The air conditioner ECU 100 outputs an opening drive command to the corresponding window driving units 222 and 224 so that the opening area is increased. As a result, as shown in FIG. 14B, the power window G of the left front seat (passenger seat) is in a half-open state with respect to the window frame W, while the power window of the right rear seat is FIG. As shown in (a), the power window G is fully opened with respect to the window frame W. The opening area O (FIG. 14B) of the power window of the left front seat (passenger seat) is the ventilation inlet, and the opening area O of the power window of the right rear seat (FIG. 14A) is for ventilation. An air flow is formed according to Bernoulli's theorem in the form of an outlet. That is, when simultaneously opening a pair of power windows located on different sides in the vehicle width direction, the air windows as shown in FIG. Therefore, the air in the vehicle can be discharged efficiently.

  In the present embodiment, it is assumed that the remaining power window that has not been opened is closed as shown in FIG. However, for example, when these remaining power windows are in an open state, an audio warning is output from the audio output device 340 to close these remaining power windows at the stage before S13 and S14. The power window closing drive command may be output to the corresponding window drive units 221 and 223 to close the power windows of the seats to be driven (here, the right front seat (driver seat) and the left rear seat). From the viewpoint of forcibly creating a stronger airflow in a predetermined direction (the diagonal direction of the vehicle), it is desirable to close the power window that is not located in the direction in which the airflow should flow.

  When S13 and S14 are completed, the process proceeds to S15. In S15, the direction in which the air-conditioning airflow is blown by the in-vehicle air conditioner is controlled so as to be the direction from one power window that is open in the vehicle width direction to the other power window. More specifically, the air conditioner ECU 100 is configured so that the air-conditioning airflow from the air outlet of the in-vehicle air conditioner is directed from a power window having a small opening to a power window having a large opening. Drive control of the grill drive unit 121 is performed. Here, in this embodiment, the open state of the power window of the right rear seat that was opened in S14 is more than the open state of the power window of the left front seat (passenger seat) that was opened in S13. Since the opening area is large, the grill of the in-vehicle air conditioner is turned to the right rear. Thereby, as shown in FIG. 12, the air flow from the left front seat (passenger seat) side to the right rear seat side is assisted, and a stronger air flow in that direction is created. Further, the grill is directed upward while maintaining its horizontal orientation. This creates an airflow that is difficult to be blocked by the seat. In S16, in order to create a strong flow of airflow, the blower air volume of the in-vehicle air conditioner is set to a predetermined air volume value, and an air-conditioned airflow of a predetermined air volume is generated from the outlet (symbols 8a and 8b in FIG. 12). Blow out. In the present embodiment, the blower air volume is maximized so that the air is blown out from the outlets 8a and 8b with the maximum air volume.

  Subsequently, in S17, detection result information is acquired from the inside air sensor 111 and the outside air temperature sensor 112 every predetermined time T3 (for example, 10 seconds). Based on the detection result information, when the vehicle interior temperature is equal to or lower than the sum of the vehicle exterior temperature and the predetermined temperature K1, the process proceeds to S31 in FIG. If the in-vehicle temperature is higher than the sum, the process proceeds to S19, and it is determined whether or not a predetermined time T4 (for example, 60 seconds) has elapsed since the end of S16. And if predetermined time T4 has passed, it will progress to S31 of FIG. 6, and if it has not passed, it will return to S17. Note that these time measurements are performed by a timer function provided in the microcomputer 101.

  In S17, when the temperature difference between the in-vehicle temperature detected by the inside air sensor 111 and the outside temperature detected by the outside air sensor 112 becomes equal to or less than the predetermined temperature K1, the process proceeds to S31 in FIG. However, it may be determined to proceed to S31 in FIG. 6 when the in-vehicle temperature detected by the inside air sensor 111 is equal to or lower than a predetermined temperature.

  In S31 of FIG. 7, a display screen 32 shown in FIG. 10 (referred to as screen 2 in FIG. 10) is displayed as guidance guidance display for ventilation operation. Subsequently, in S32, it is determined whether or not the touch switch 32a is operated among the touch switches 32a and 32b for selecting ventilation start (ventilation start) and ventilation stop displayed on the display screen 32. In addition to the touch switches 32a and 32b, the display screen 32 also displays ventilation direction information 38 indicating how air flows when ventilation start is selected in the same screen. In the ventilation direction information 38, the power window that is in the open state and the power window that is in the closed state are displayed so as to be identifiable, and they are set opposite to the display screen 31. Further, as the display screen 32 is displayed in S31, the open / close state of each power window during ventilation, the direction of air flow during ventilation, touch switches 32a and 32b, and the like are described. (Guidance guidance for ventilation operation and ventilation operation).

  If the touch switch 31a for starting ventilation is not operated in S32, the process proceeds to S42. In S42, it is determined whether or not the ventilation stop touch switch 32b is operated. When the touch switch 32b is operated, the process proceeds to S44 and S45. When the touch switch 32b is not operated, the process proceeds to S43, and it is determined whether or not a predetermined time T2 (for example, 30 seconds) has elapsed since the engine start was detected. If it has not elapsed, the process returns to S42, and if it has elapsed, the process proceeds to S44 and S45. In S44 and S45, the audio output device 340 outputs a warning to the effect that the power window opened in S13 and S14 in FIG. 6 is closed, and then outputs the power window to the corresponding window driver 222, 224. Is output to close the power window of the seat to be driven. Here, at S44, a warning is output by voice to close the power window of the left front seat (passenger seat) and the power window is closed, and then the power window of the right rear seat is closed at S45. A warning to that effect is output and the power window is closed. In step S46, the air conditioner ECU 100 starts normal control of the air conditioner.

  On the other hand, if it is determined in S32 that the ventilation start touch switch 32a has been operated, the process proceeds to S33. In S33 and S34, the audio output device 340 outputs a warning to the effect that the power window opened in S13 and S14 in FIG. 6 is closed, and then outputs the power window to the corresponding window driver 222 or 224. Is output to close the power window of the seat to be driven. This is the same processing as S27 and S28 described above.

  Subsequently, in S35, the voice output device 340 outputs a voice to the effect that the power window of the right front seat (driver's seat) is opened, and then outputs an open drive command for the power window to the corresponding window drive unit 221. As a result, the power window of the right front seat (driver's seat) is opened. Subsequently, in S36, the voice output device 340 outputs a voice to the effect that the left rear seat power window is opened, and then outputs a corresponding power window opening drive command to the corresponding window drive unit 223. As a result, the left rear seat power window is opened.

  That is, by completing S35 and S36 in FIG. 7, in S13 and S14 in FIG. 6, the first-side front seat power window and the second-side rear seat power window in the vehicle width direction are opened. The first mode that has been switched is switched to a second mode in which the first-side rear seat power window in the vehicle width direction and the second-side front seat power window are opened. Air flows are generated in different directions in the first mode and the second mode. However, also in the second mode, as in the first mode, the pair of power windows that have been opened are opened at different opening degrees, and a forced air flow is formed. In the second mode in the present embodiment, an air flow as shown in FIG. 13 is forcibly formed.

  When S36 ends, the process proceeds to S37. In S <b> 37, the air conditioner ECU 100 operates the grill drive unit 121 so that the air-conditioning air current is blown out from the air outlet by the in-vehicle air conditioner from the power window having a small opening toward the power window having a large opening. Is controlled. Here, in this embodiment, the open state of the power window of the left rear seat that was opened in S36 is more than the open state of the power window of the right front seat (driver's seat) that was opened in S35. Since the opening area is large, the grill is directed to the left rear. As a result, as shown in FIG. 13, the air flow from the right front seat (driver's seat) side to the left rear seat side is assisted, and a stronger airflow in that direction is created. Further, in the vertical direction, the position in S15 is maintained.

  Subsequent S38 to S41 are the same as S15 to S18 described above, and a description thereof will be omitted. If the vehicle interior temperature is equal to or lower than the sum of the vehicle exterior temperature and the predetermined temperature K2 in S40, or if a predetermined time T4 (for example, 60 seconds) has elapsed from the end of S38 in S41. The process proceeds to S51 in FIG. 8, and if it has not elapsed, the process returns to S38. Note that these time measurements are performed by a timer function provided in the microcomputer 101.

  In S40, when the temperature difference between the in-vehicle temperature detected by the inside air sensor 111 and the outside temperature detected by the outside air sensor 112 is equal to or less than a predetermined temperature K2 (for example, 10 ° C.) that is smaller than the predetermined temperature K1. 8 is determined to proceed to S51 in FIG. 8, but may be determined to proceed to S51 in FIG. 8 when the in-vehicle temperature detected by the inside air sensor 111 is equal to or lower than a predetermined temperature. Good.

  In S51 of FIG. 8, a display screen 33 (referred to as screen 3 in FIG. 8) shown in FIG. 11 is displayed as guidance guidance display for ventilation operation. Subsequently, in S52, it is determined whether or not the touch switch 33a displayed on the display screen 32 and instructing the start of power window full close (OK switch) is operated. In addition to the touch switch 33a, the display screen 33 also displays ventilation direction information 40 indicating how air flows when the touch switch 33a is selected and operated within the same screen. In the ventilation direction information 39, a power window that is in an open state and a power window that is in a closed state are displayed in an identifiable manner, and the display screen 33 indicates that all power windows are in a closed state. Yes. Further, as the display screen 33 is displayed in S51, the open / close state of each power window after the touch switch 33a, the description of the touch switches 32a and 32b, and the like are performed.

  The subsequent processes in S53 to S57 are the same as the processes in S42 to S46, and thus description thereof is omitted.

  The ventilation processing program is immediately interrupted when a manual operation for manually opening and closing the power window (operation to the window opening and closing operation units 211 to 214) is performed during execution, and normal control of the on-vehicle air conditioner is performed. Start.

  Thus, when the air conditioner ECU 100 executes the ventilation processing program shown in FIGS. 5, 6, 7, and 8, the ventilation control means (blowing direction control means), the usage guide information output means, the ventilation operation of the present invention. Functions as an interruption means. That is, the air conditioner ECU 100 performs the functions of these means.

  As mentioned above, although one Embodiment of this invention was described, these are only illustrations to the last, and this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. is there.

  For example, the main body that executes the ventilation processing program may be the door ECU 200 instead of the air conditioner ECU 100, or may be a configuration in which a dedicated ECU is provided.

  Further, the ventilation mode is not limited to the case where the ventilation direction is determined in two directions on the vehicle diagonal line as described above. For example, when an openable sunroof S provided on the ceiling of the vehicle is provided, the openable sunroof S is provided. You may have the ventilation mode made into an open state. In this case, the power window of the front seat of the vehicle may be in an open state that is smaller than the opening area of the openable sunroof S, and an air flow as shown in FIG. 15 may be provided. Further, in this case, the grill of the in-vehicle air conditioner can be set at an upward position facing the openable sunroof S to assist the air flow.

  In addition, in order to make it possible to change the ventilation conditions in the ventilation mode, that is, the setting conditions of the power window and the on-vehicle air conditioner in the ventilation mode, a ventilation condition storage unit that stores the setting contents of the ventilation conditions that can be changed and a user operation A ventilation condition setting input unit that receives the setting input of the ventilation condition, and a ventilation condition changing unit that changes the setting content of the ventilation condition stored in the ventilation condition storage unit based on the received setting input of the ventilation condition. It can be provided and configured. Thereby, ventilation conditions can be changed into the conditions according to a user preference.

  The changeable ventilation conditions include, for example, the opening area of the power window in the ventilation mode, the ventilation mode duration (predetermined time T3 in S19 in FIG. 6 and S41 in FIG. 7), the blower air volume of the in-vehicle air conditioner in the ventilation mode, and ventilation A temperature measurement cycle in the mode (a predetermined time T3 in S17 in FIG. 6 and S39 in FIG. 7) or the like can be set.

  Specifically, the ventilation condition can be set from the ventilation condition setting screen 40 as shown in FIG. The screen 40 in FIG. 16 is displayed on the display device 330 of the navigation device 300, and is displayed by operating a ventilation condition setting switch provided in the navigation device. And touch operation with respect to the touch switch 41 (41a, 41b), 42, 43, 44 (44a, 44b) displayed on the screen 40 of FIG. 16 is performed, and the corresponding ventilation conditions (open area of the power window, ventilation mode) The ventilation conditions can be changed by touching the touch switch 45 when setting and confirming the duration, the blower air volume of the in-vehicle air conditioner in the ventilation mode, and the temperature measurement cycle in the ventilation mode. As a result, the previous ventilation condition information stored in the non-volatile memory of the air conditioner ECU that forms the ventilation condition storage unit is overwritten, and the air conditioner ECU reads these setting conditions in the next ventilation processing program. Execute the process. The ventilation condition changing means functions as the CPU of the air conditioner ECU executes the above processing, and the ventilation condition setting input unit includes the touch switches 41 (41a, 41b), 42, 43, 44 (44a). , 44b), 45.

  Moreover, you may change the initial process shown in FIG. 5 among ventilation processing programs like FIG. In S101 of FIG. 17, an engine start trigger signal is acquired as in S1 of FIG. When the IVA switch 11d is ON in the engine start state, or when the IVA switch 11d is operated by the user within a predetermined time T1 (for example, 60 seconds) from the engine start detection, the process proceeds to S102. If there is no operation to the IVA switch 11d within the predetermined time T1, the process proceeds to S113, and the air conditioner ECU 100 starts normal control of the air conditioner.

  In S102, when the IVA switch 11d is turned on, the process proceeds to S103. S102 and S103 are the same processes as S2 and S3 in FIG. Following S103, in S104, the in-vehicle temperature detected by the inside air sensor 111 and the outside temperature detected by the outside air sensor 112 are detected, and the process proceeds to S105. In S105, if the detected temperature difference between the in-vehicle temperature and the outside temperature is equal to or lower than the predetermined temperature K0, the process proceeds to S110, and in S110, the notification that ventilation is not required is issued (ventilation unnecessary notification means). Then, the process proceeds to S113, and normal control of the air conditioner is started. On the other hand, if the detected temperature difference between the in-vehicle temperature and the outside temperature exceeds a predetermined temperature K0 (for example, the same temperature as the predetermined temperature K1) in S105, the process proceeds to S106.

  In S106, weather information reflecting the current weather around the vehicle is acquired. Specifically, information for determining whether the present is rainy or is in a state estimated to be rainy is acquired. In this embodiment, the weather information concerning rainy weather is acquired by detecting water droplets attached to the windshield with a rain sensor (weather information acquisition means). Note that weather information may be acquired by wireless communication from an external information center using a communication device (weather information acquisition means) mounted on the navigation device.

  In step S107, based on the acquired weather information, if the current weather around the vehicle is rain, the process proceeds to step S111, and the ventilation failure notifying that the weather state is not suitable for ventilation as shown in FIG. The appropriate weather information notification screen 50 is displayed (ventilation inappropriate weather information notification means). On this screen, characters indicating that the current weather around the vehicle is not suitable for ventilation are indicated (reference numeral 50c). Then, the user is prompted to perform a selection operation on the touch switches 50a and 50b by screen display and voice guidance, and it is determined whether ventilation is to be executed based on the selected operation. When it is determined that the touch switch 50b is touched and ventilation is not performed, the process proceeds to S113, and normal control of the air conditioner is started. When it is determined that the touch switch 50a is touched and ventilation is performed, the process proceeds to S108.

  In S108, the odor presence information reflecting the odor presence state around the vehicle is acquired. Here, the detection result from the exhaust gas sensor is acquired. In S109, it is determined whether or not a bad odor exists around the current vehicle or whether or not it is estimated that a bad odor exists. Here, when the exhaust gas level detected by the exhaust gas sensor (bad odor presence information acquisition means) exceeds a predetermined level, it is determined that bad odor exists. If a bad odor exists, the process proceeds to S112, and an inappropriate ventilation weather information notification screen 60 for warning that a bad odor exists is displayed as shown in FIG. 19 (bad odor warning means). This screen displays characters indicating that the current weather around the vehicle is not suitable for ventilation (reference numeral 60c). Then, the user is prompted to perform a selection operation on the touch switches 60a and 60b through screen display and voice guidance, and it is determined whether ventilation is to be executed based on the selection operation performed. When it is determined that the touch switch 60b is touched and ventilation is not performed, the process proceeds to S113, and normal control of the air conditioner is started. When it is determined that the touch switch 60a is touched and ventilation is performed, the process of FIG. 5 is terminated and the process proceeds to S11 of FIG.

  The malodor presence information may be malodor point data stored in association with map data in the navigation device. In this case, on the map data, for example, a barn or a road with a large amount of exhaust gas emission is registered as a bad odor point, and it is determined that a bad odor exists when the current vehicle position is close to those points. You can also.

  When the CPU of the air conditioner ECU 100 that forms the ventilation control means executes the ventilation processing program of FIG. 17 described above, the temperature difference between the detected vehicle interior temperature and the vehicle exterior temperature becomes less than a predetermined value. It functions as a ventilation operation suppression means that suppresses ventilation operation control. Ventilation that obtains weather information that reflects the weather around the vehicle and notifies that the weather condition is not suitable for ventilation when it is determined that the weather condition is not suitable for ventilation from the acquired weather condition. In addition to functioning as inappropriate weather information notification means, it also functions as ventilation action suppression means for suppressing ventilation action when it is determined from the acquired weather condition that the weather condition is not suitable for ventilation. Furthermore, based on the acquired odor presence information, it functions as a odor warning means for warning the presence of the odor, and similarly suppresses ventilation operation control when the acquired odor presence information reflects the presence of the odor. Also functions as a ventilation action suppression means.
