Note that the number of seat temperature control devices 30 provided for the rear seats is not particularly limited.

[0017] The seat heater 31 includes a heating member such as a heating wire, and is a device that warms the back portion of the occupant sitting on the seat by the heat generated from the heating member. The heating member is incorporated, for example, in the seat cushion portion (seat surface portion) and the seat back portion that constitute the seat. The back portion of the occupant includes the occupant's back, waist, buttocks, and legs. The seat heater 31 is controlled by the controller 10. Examples of control commands output from the controller 10 to the seat heater 31 include a heating command and a set temperature. When, for example, a control command including a heating command and a set temperature is input from the controller 10 to the seat heater 31, the seat heater 31 causes the heating member to generate heat so that the surface temperature of the seat becomes the set temperature. Note that the control method of the seat heater 31 is not particularly limited, and a method known at the time of filing can be appropriately used.

[0018] The air-conditioning seat 32 is a device that has a plurality of ventilation openings and provides a cooling sensation to the back portion of an occupant sitting on the seat by performing ventilation through the plurality of ventilation openings. The ventilation openings are provided, for example, near the seat surface in the seat cushion portion and the seat back portion of the seat. The air-conditioning seat 32 has a blowing function and / or a dehumidifying function. The air-conditioning seat 32, for example, blows out cold air with a predetermined air volume from the ventilation openings to give a cooling sensation to the back portion of the occupant. Also, the air-conditioning seat 32 removes moisture, for example, by sucking air (exhausting air) from the ventilation openings, and gives a cooling sensation to the back portion of the occupant. The air-conditioning seat 32 is controlled by the controller 10. Examples of control commands output from the controller 10 to the air-conditioning seat 32 include a blowing command, a dehumidifying command, a set air volume, and a set temperature. The air-conditioning seat 32, for example, when a control command including a blowing command, a set air volume, and a set temperature is input from the controller 10, sends out air at the set temperature from the ventilation openings by the set air volume. Also, the air-conditioning seat 32, for example, when a control command including a dehumidifying command is input from the controller 10, sucks air from the ventilation openings. Note that the control method of the air-conditioning seat 32 is not particularly limited, and a method known at the time of filing can be appropriately used. In the following description, the air-conditioning seat 32 will be described as having at least a blowing function.

The steering heater 33 includes a heating member such as a heating wire incorporated in the steering wheel, and is a device that warms the hand of the driver in contact with the steering wheel by the heat generated from the heating member. The steering heater 33 is controlled by the controller 10. Examples of control commands output from the controller 10 to the steering heater 33 include a heating command and a set temperature. The steering heater 33, for example, when a control command including a heating command and a set temperature is input from the controller 10, causes the heating member to generate heat so that the surface temperature of the steering wheel becomes the set temperature. Note that the control method of the steering heater 33 is not particularly limited, and a method known at the time of filing can be appropriately used.

[0020] The air conditioner 34 is a device that adjusts the temperature, humidity, etc. of the air inside the vehicle cabin and is an air conditioner. The air conditioner 34 is composed of an air conditioning system including a compressor and the like, and has an air outlet that blows air into the passenger's seat space, a front windshield, and / or a defroster for removing fog on the glass again. The air outlet is provided on the dashboard or at the lower part of the dashboard. The air outlet on the dashboard is a front air outlet and is arranged to blow air toward the front of the seat. The air outlet at the lower part of the dashboard is a lower air outlet and is arranged to blow air toward the lower part of the seat. The direction of the air flow changes according to the direction inside the air outlet. The defroster has an air outlet that blows air from the front part of the dashboard along the front windshield and outputs the air generated by the air conditioning system. The air conditioner 34 is controlled by the controller 10. Examples of the control commands output from the controller 10 to the air conditioner 34 include a blowing command, a dehumidifying command, a set temperature, a set air volume, and a set air flow direction. When, for example, a control command including a blowing command, a set temperature, a set air volume, and a set air flow direction is input from the controller 10 to the air conditioner 34, the air conditioner 34 sends out air at the set temperature from the air outlet set by the set air flow direction by the set air volume. Note that the control method of the air conditioner 34 is not particularly limited, and a method known at the time of filing can be appropriately used.

[0021] The controller 10 is composed of a computer equipped with hardware and software, and has a memory storing programs and a CPU or the like for executing the programs stored in this memory. Note that as an operation circuit, an MPU, a DSP, an ASIC, an FPGA, etc. can be used instead of or together with the CPU. The controller 10 has, as functional blocks, a display control unit 11 for controlling the display screen of the display 2 and an environmental temperature control unit 12 for controlling the environmental temperature control device 3. The controller 10 realizes each function of the functional blocks by software stored in the memory. Also, the controller 10 has not only the display control unit 11 and the environmental temperature control unit 12, but also control blocks for controlling various systems in the vehicle interior, such as a function for controlling an audio system and a function for controlling a navigation system, and controls not only the display 2 and the environmental temperature control device 3 but also other in-vehicle devices. Note that various systems included in the vehicle are controlled by a plurality of ECUs, but in FIG. 1, the plurality of ECUs are illustrated as the controller 10. Also, the display control device of the present invention only needs to have at least the display control unit 11 of the controller 10, and the environmental temperature control system 1 may be configured such that blocks other than the controller 10 have the other functions described above.

[0022] The display control unit 11 controls the display screen of the display 2. Also, when the display control unit 11 detects a touch operation by the display 2, it accepts an operation command according to the position of the touch operation and the type of the touch operation on the display screen. The display control unit 11 generates an image representing the operation state of the environmental temperature control device 3. The display control unit 11 outputs a control command for displaying a screen including the generated image to the display 2. The operation state of the environmental temperature control device 3 is displayed so that the occupant can identify it by changing the form, color, pattern, animation, etc. of the image included in the screen. Also, the display control unit 11 outputs the accepted operation command to the environmental temperature control unit 12.

[0023] The environmental temperature control unit 12 controls the environmental temperature control device 3 based on the operation command received by the display control unit 11. The operation command includes the device to be controlled among the various devices included in the environmental temperature control device 3, the operation mode of the device to be controlled, the control target item of the device to be controlled, and the control amount in the control target item. The environmental temperature control unit 12 controls the device to be controlled according to the operation mode, the control target item, and the control amount. Also, the environmental temperature control unit 12 manages the operation state of the environmental temperature control device 3 and the environment inside the vehicle cabin. The environmental temperature control device 3 has operation modes of an auto mode and a manual mode. When the environmental temperature control device 3 operates in the auto mode, the environmental temperature control unit 12 generates a control command to operate the environmental temperature control device 3 so that the entire vehicle cabin or the passenger's seat space reaches the set temperature based on the detection results from a temperature sensor, a humidity sensor, etc., and outputs the generated control command to the environmental temperature control device 3. On the other hand, when the environmental temperature control device 3 operates in the manual mode, the environmental temperature control unit 12 generates a control command to operate the environmental temperature control device 3 according to the set item set by the passenger, and outputs the generated control command to the environmental temperature control device 3.

[0024] Taking the case where the seat heater 31 operates in the manual mode as an example, the environmental temperature control unit 12 specifies the control item of the seat heater 31 from the operation command, and controls the on / off, heating temperature, etc. of the seat heater 31 according to the specified control item. The environmental temperature control unit 12 outputs a control command corresponding to the control item to the seat heater 31. The control items are predetermined according to the specifications of the seat heater 31, such as temperature setting, heat generation amount, etc.

[0025] Taking the case where the air-conditioning seat 32 operates in the manual mode as an example, the environmental temperature control unit 12 identifies the control items of the air-conditioning seat 32 from the operation command, and controls the on / off, set temperature, air volume, etc. of the air-conditioning seat 32 according to the identified control items. The environmental temperature control unit 12 outputs a control command corresponding to the control item to the air-conditioning seat 32. The control items are predetermined according to the specifications of the air-conditioning seat 32, such as air volume setting, temperature setting, etc. In this embodiment, the seat heater 31 and the air-conditioning seat 32 are not operated simultaneously and are selectively selected by a touch operation. However, according to the specifications of the air-conditioning seat 32, the seat heater 31 and the air-conditioning seat 32 may operate simultaneously. For example, when the air-conditioning seat 32 is provided with a warm air function for blowing warm air in addition to a cold air function for blowing cold air, the environmental temperature control unit 12 may operate the seat heater 31 and the air-conditioning seat 32 simultaneously according to the control item.

[0026] Taking the case where the steering heater 33 operates in the manual mode as an example, the environmental temperature control unit 12 identifies the control items of the steering heater 33 from the operation command, and controls the on / off, heat generation temperature, etc. of the steering heater 33 according to the identified control items. The environmental temperature control unit 12 outputs a control command corresponding to the control item to the steering heater 33. The control items are predetermined according to the specifications of the steering heater 33, such as temperature setting, heat generation amount, etc.

[0027] Taking the case where the air-conditioning equipment 34 operates in the manual mode as an example, the environmental temperature control unit 12 identifies the control items of the air-conditioning equipment 34 from the operation command, and controls the on / off of the air-conditioning system, the selection of the air outlet, the air volume, temperature, air direction, etc. of the air blown out from the air outlet according to the identified control items. The environmental temperature control unit 12 outputs a control command corresponding to the control item to the air-conditioning equipment 34. The control items are predetermined according to the specifications of the air-conditioning equipment 34, such as air volume setting, air direction setting, temperature setting, selection of the air outlet, etc.

[0028] The control of the environmental temperature control device 3 by the environmental temperature control unit 12 and the control of the display screen by the display control unit 11 are associated by an application (software). The display control unit 11 receives an operation command through a touch operation on the display screen, and the environmental temperature control unit 12 outputs a control item corresponding to the operation command as a control command to the environmental temperature control device 3. For example, when the operation of the environmental temperature control device 3 is changed by the environmental temperature control unit 12 according to the environment in the vehicle interior while the environmental temperature control device 3 is operating in the auto mode, the environmental temperature control unit 12 outputs a signal indicating the operation state of the environmental temperature control device 3 after the change to the display control unit 11. Based on the signal from the environmental temperature control unit 12, the display control unit 11 generates an image indicating the current operation state of the environmental temperature control device 3. The display control unit 11 outputs a control command for displaying the generated image to the display 2. Thereby, the occupant can operate the environmental temperature control device 3 using the display 2 and confirm the operation state of the environmental temperature control device 3 from the display screen of the display 2. Also, when the operation state of the environmental temperature control device 3 is automatically changed by the auto mode, the occupant can confirm the change in the operation state of the environmental temperature control device 3 from the display screen of the display 2.

[0029] Next, with reference to FIGS. 3 to 9, a control method of the environmental temperature control device 3 using the display 2 and the display screen of the display 2 will be described. FIGS. 3 to 9 are each an example of a display screen displayed on the display 2. As shown in FIGS. 3 to 9, the display screen of the display 2 is horizontally long, but the shape of the display 2 and the shape of the display area of the display 2 are not limited to the horizontally long shape. Also, in FIGS. 3 to 9, the x-axis indicates the vehicle width direction (left-right direction) of the vehicle, the y-axis indicates the depth in the vehicle traveling direction (forward direction), and the z-axis indicates the height direction (up-down direction).

[0030] FIG. 3 is an example of a home screen displayed on the display 2. For example, when the ignition switch of the vehicle is turned on by the occupant, a signal indicating the start of the vehicle is input to the display control unit 11. The display control unit 11 reads out image data representing the home screen from the memory. The display control unit 11 outputs a control command for displaying the image data read from the memory to the display 2. The home screen includes a passenger seat icon associated with the passenger seat and a driver's seat icon associated with the driver's seat, which will be described later. Also, as in the example of FIG. 3, the home screen 41 is not limited to the screen that is first displayed after the vehicle is started, and may be a screen that is displayed while the vehicle is stopped or running. When another system other than the environmental temperature control system 1 is activated by the operation of the occupant, the display control unit 11 outputs a control command for displaying a home screen including a screen corresponding to the activated system to the display 2. In the example of FIG. 3, a navigation screen 45 in which the current location icon P is superimposed on the map information is displayed on the home screen 41. The current location icon P is an icon indicating the current location of the vehicle. The home screen 41 in FIG. 3 is a home screen in a scene where the navigation system is activated by the operation of the occupant and the driver is provided with route guidance by the navigation system. Also, for example, when the audio system is activated by the operation of the occupant, the display control unit 11 outputs a control command for displaying a home screen including a music information screen to the display 2. The music information screen is a screen showing information on the music flowing in the vehicle interior by the audio system. The type of screen included in the home screen is determined in advance according to the specifications of the vehicle.

[0031] As shown in FIG. 3, the home screen 41 includes a passenger seat icon 42L, a driver's seat icon 42R, a menu section 43, and a navigation screen 45. The navigation screen 45 is located approximately at the center of the home screen 41 and is the main screen that occupies most of the display screen on the display 2. The passenger seat icon 42L, the driver's seat icon 42R, and each icon included in the menu section 43 are icons that can be touched and operated by the passengers, and each icon has a different use. The passenger seat icon 42L is an icon for displaying a passenger seat setting screen described later, and the driver's seat icon 42R is an icon for displaying a driver's seat setting screen described later. The air conditioning icon 431 included in the menu section 43 is an icon for displaying an air conditioning setting screen described later. Note that the home screen 41 in FIG. 3 is an example, and the main screen of the home screen 41 is not limited to the navigation screen 45. Also, the number of screens included in the home screen 41 is not particularly limited, and different from the example in FIG. 3, the home screen 41 may include two screens divided into two in the z-axis direction.

[0032] The co-driver seat icon 42L is associated with the co-driver seat and is located on the home screen 41 below the navigation screen 45 and on the co-driver side rather than the driver side. As shown in Figure 3, the co-driver seat icon 42L includes a set temperature display 421L and an operating state display 422L. The set temperature display 421L is located to the left of the operating state display 422L and represents the set temperature on the co-driver seat setting screen. The operating state display 422L represents the operating state (on state / off state) of the seat temperature control device 30 of the co-driver seat. That is, the co-driver seat icon 42L is an icon representing the operating state of the seat temperature control device 30 of the co-driver seat on the co-driver seat setting screen. Also, in the example of Figure 3, as the operating state display 422L, images showing the co-driver seat heater 31 and the air-conditioned seat 32 are displayed in gray. The display color of the icon part representing the fan and the icon part representing the heat generation of the seat heater in the operating state display 422L changes according to the operating states of the seat heater 31 and the air-conditioned seat 32. For example, when the seat heater 31 is operating, the icon part representing the fan in the operating state display 422L is displayed in orange, and when the seat heater 31 is stopped, the icon part is displayed in gray. Also, for example, when the air-conditioned seat 32 is operating, the icon part representing the fan in the operating state display 422L is displayed in blue, and when the air-conditioned seat 32 is stopped, the icon part is displayed in gray. In the example of Figure 3, the operating state display 422L represents that the seat heater 31 and the air-conditioned seat 32 are in the off state. Also, when the seat temperature control device 30 of the co-driver seat is operating in the auto mode and the operation of the seat temperature control device 30 of the co-driver seat is changed by the environmental temperature control unit 12 according to the environmental temperature in the vehicle interior, the display control unit 11 outputs a control command to change the operating state display 422L according to the changed operating state of the seat temperature control device 30 to the display 2. In the example of Figure 3, for example, when the co-driver seat heater 31 is switched from off to on by the auto mode, a control command to change the icon part representing the fan in the operating state display 422L from gray to orange is output to the display 2. Thereby, the occupant can easily grasp the change in the operating state of the seat temperature control device 30 of the co-driver seat by the auto mode.In particular, as in the example of FIG. 3, since the passenger seat icon 42L is located closer to the passenger seat side than the driver's seat on the home screen 41, the passenger in the passenger seat can easily grasp the change in the operating state of the seat temperature control device 30 for the passenger seat, and the visibility of the operating state of the seat temperature control device 30 can be improved. Note that the passenger seat icon 42L shown in FIG. 3 is merely an example of a display mode representing the setting content of the seat temperature control device 30 for the passenger seat, and does not limit the display mode of the passenger seat icon 42L.

[0033] The passenger seat icon 42L and the driver's seat icon 42R are positioned in a substantially line-symmetrical relationship with respect to the center line of the home screen 41 parallel to the z-axis. The driver's seat icon 42R is associated with the driver's seat and is located on the home screen 41 below the navigation screen 45 and on the driver's seat side rather than the passenger seat side. As shown in FIG. 3, the driver's seat icon 42R includes a set temperature display 421R, an operation state display 422R, and an operation state display 423R. The set temperature display 421R is located on the right side of the operation state displays 422R and 423R and represents the set temperature on the driver's seat setting screen. The operation state display 422R is located on the right side of the operation state display 423R and represents the operation state (on state / off state) of the seat temperature control device 30 of the driver's seat. The operation state display 423R represents the operation state (on state / off state) of the steering heater 33. The operation state display 432R is included in the driver's seat icon 42R but not in the passenger seat icon 42L. The driver's seat icon 42R is an icon representing the operation state of the seat temperature control device 30 of the driver's seat on the driver's seat setting screen. Since the display mode of the set temperature display 421R is the same as that of the set temperature display 421L, the above description is incorporated by reference. Also, the display mode of the operation state display 422 is different in that the icon representing the seat is displayed facing the icon representing the seat in the set temperature display 421L, but otherwise it is the same as the display mode of the set temperature display 421L, so the above description is incorporated by reference. The operation state display 422R in FIG. 3 represents that the seat heater 31 and the air-conditioned seat 32 of the driver's seat are in the off state. Also, in the example of FIG. 3, as the operation state display 423R, an icon indicating the steering heater 33 is displayed in gray. The operation state display 423R is displayed in orange when the steering heater 33 is in the on state and in gray when the steering heater 33 is in the off state. In the example of FIG. 3, the operation state display 423R represents that the steering heater 33 is in the off state. Also, when the operation state of the seat temperature control device 30 and / or the steering heater 33 of the driver's seat is changed by the auto mode, the display control unit 11 outputs a control command to change the operation state displays 422R and 423R to the display 2 in the same manner as the seat temperature control device 30 of the passenger seat.In the example of FIG. 3, for example, when the steering heater 33 of the driver's seat is switched from off to on in the auto mode, a control command for changing the color of the image representing the steering heater 33 from gray to orange is output to the display 2. Thereby, the occupant can easily grasp the change in the operating state of the seat temperature control device 30 and / or the steering heater 33 of the driver's seat in the auto mode. In particular, as in the example of FIG. 3, since the driver's seat icon 42R is located closer to the driver's seat than the passenger seat on the home screen 41, the driver can easily grasp the change in the operating state of the seat temperature control device 30 and the steering heater 33 of the driver's seat, and the visibility of the operating state of the seat temperature control device 30 and the steering heater 33 can be improved.

[0034] The menu section 43 is a section for displaying each menu that can be selected by the occupant. A plurality of icons including the air-conditioning icon 431 are arranged in the z-axis direction in the menu section 43. The menu section 43 is located on the right side of the navigation screen 45 and closer to the driver's seat than the passenger seat on the home screen 41. The air-conditioning icon 431 is associated with the air-conditioning device 34 and is located at the bottommost stage in the menu section 43. Note that the number and use of the other icons included in the menu section 43 excluding the air-conditioning icon 431 are not particularly limited. The number and use of the icons included in the menu section 43 are determined in advance according to the specifications of the vehicle.

[0035] Next, the operation of the display control unit 11 when each of the passenger seat icon 42L, driver's seat icon 42R, and air conditioning icon 431 shown in FIG. 3 is touch-operated will be described. The display control unit 11 outputs different control commands to the display 2 according to the type of the touch-operated icon, and causes the display 2 to display the screen associated with each icon. When one of the seat icons of the passenger seat icon 42L and the driver's seat icon 42R is operated, the display control unit 11 outputs a control command for causing the display 2 to display the setting screen of one of the seats of the passenger seat icon 42L and the driver's seat icon 42R. The setting screen includes a display in which the occupant can input control items related to the temperature control of one of the seat icons operated on the home screen 41. Also, the setting screen is located on one seat side of the display screen of the display 2 rather than the other seat of the passenger seat and the driver's seat. Further, when the air conditioning icon 431 is operated, the display control unit 11 outputs a control command for causing the display 2 to switch the display from the home screen 41 to the air conditioning setting screen.

[0036] The co-pilot seat setting screen displayed on the display 2 when the occupant touches the co-pilot seat icon 42L will be described. When the occupant touches the co-pilot seat icon 42L, the display control unit 11 detects the position touched on the home screen 41 and recognizes that the detected position corresponds to the position of the co-pilot seat icon 42L. The touch operation on the co-pilot seat icon 42L includes the touch operation on the set temperature display 421L and the touch operation on the operation state display 422L. When a touch operation is performed on either the set temperature display 421L or the operation state display 422L, the display control unit 11 recognizes that a touch operation has been performed on the co-pilot seat icon 42L. The display control unit 11 reads out the image data of the co-pilot seat setting screen from the memory. The display control unit 11 outputs a control command (second control command L) for displaying the image data of the co-pilot seat setting screen read from the memory to the display 2. In the present embodiment, the second control command L includes a control command for displaying the co-pilot seat setting screen superimposed on the home screen 41. The second control command L also includes a control command for displaying the co-pilot seat setting screen at a position covering the co-pilot seat icon 42L. Further, as in the example of FIG. 3, when the current location icon P is displayed on the home screen 41, the second control command L includes a control command for displaying the current location icon P in the area of the home screen 41 where the co-pilot seat setting screen is not superimposed. The second control command L also includes a control command for reducing the brightness of the home screen 41 compared to before the co-pilot seat setting screen is displayed.

[0037] FIG. 4 is an example of a passenger seat setting screen 51 displayed on the display 2 when the passenger seat icon 42L in the home screen 41 shown in FIG. 3 is touch-operated. The passenger seat setting screen 51 is a screen for the occupant to set the seat temperature control device 30 of the passenger seat. The passenger seat setting screen 51 is displayed within a new window generated on the home screen 41. The passenger seat setting screen 51 is smaller than the home screen 41 and larger than the passenger seat icon 42L shown in FIG. 3. Also, the passenger seat setting screen 51 is located closer to the passenger seat side than the driver's seat on the display screen of the display 2. Further, the passenger seat setting screen 51 is displayed superimposed on the home screen 41 so as to cover the passenger seat icon 42L in the home screen 41. The home screen 41 has an area 41a that is not superimposed on the passenger seat setting screen 51. The brightness of the home screen 41 shown in FIG. 4 is lower than the brightness of the home screen 41 shown in FIG. 3. Note that the absolute value of the brightness of the home screen 41 shown in FIG. 4 is not particularly limited, as long as it is relatively lower than the brightness of the home screen 41 shown in FIG. 3. Due to the decrease in the brightness of the home screen 41, the passenger seat setting screen 51 is relatively emphasized, and it becomes easier for the occupant to check the display content of the passenger seat setting screen 51. Also, the current location icon P of the navigation screen 45 is displayed in the area 41a of the home screen 41. The current location icon P shown in FIG. 4 corresponds to the current location icon P shown in FIG. 3. Even when the passenger seat setting screen 51 is displayed, the driver can easily grasp the current location of the vehicle by the current location icon P. In particular, it is possible to suppress the situation where the driver in the middle of driving cannot grasp the current location of the vehicle due to the display of the passenger seat setting screen 51, which may affect the driver's driving.

[0038] The co-driver seat setting screen 51 includes a seat image 52 representing the co-driver seat, a main switch button display 53a, a mode switch button display 53b, a seat heater button display 53c, an air-conditioned seat button display 53d, a temperature adjustment bar 54, and a temperature display image 55. These button displays, bars, and images are displays through which the occupant can input control items related to the temperature control of the co-driver seat. The seat image 52 is displayed rotated by a predetermined angle (for example, in the range of 10 degrees to 45 degrees) clockwise from the forward direction of the vehicle around the z-axis compared to the actual co-driver seat. The main switch button display 53a is a display for switching the on / off of the seat temperature control device 30 of the co-driver seat by a touch operation. The button display is white when off, and when on, the white part turns orange. In the following description, the on / off displays of other button displays are similarly represented by white displays and orange displays. The mode switch button display 53b is a button display for switching the operation mode (auto mode / manual mode) of the seat temperature control device 30 of the co-driver seat. The seat heater button display 53c is a display for switching the on / off of the seat heater 31 by a touch operation. The air-conditioned seat button display 53d is a display for switching the on / off of the air-conditioned seat 32 by a touch operation. Since the seat heater button display 53 is displayed with an icon representing the seat heater 31, and the air-conditioned seat button display 53d is displayed with an icon representing the air-conditioned seat 32, the occupant can identify the devices operable by each button. Some or all of these button displays are superimposed and displayed on the seat image 52b.

[0039] The seat image 52 also includes an operation state image 52a representing the operation state of the seat temperature control device 30 for the passenger seat. The operation state image 52a includes a scale display. The scale display represents the heat generation level of the seat heater 31 for the passenger seat or the air volume level of the air-conditioned seat 32. In the example of FIG. 4, the scale display represents three graduations, but the number of graduations is not particularly limited. The display mode of the operation state image 52a changes according to the button display by the occupant and the operation on the operation state image 52a. For example, when the occupant touches the seat heater button display 53c, the display control unit 11 outputs a control command to the display 2 to change the color of the operation state image 52a from the previous display color to red, thereby changing the color of the operation state image 52a to red. Red represents the heat generation of the seat heater 31. Also, the display control unit 11 changes the scale display of the operation state image 52a according to the number of times the occupant touches the operation state image 52a. For example, when the occupant touches the operation state image 52a a plurality of times, the display control unit 11 outputs a control command to the display 2 to increase the red scale display in the positive z-axis direction so that the number of touches and the number of graduations of the scale display are linked. Also, for example, when the occupant touches the air-conditioned seat button display 53d, the display control unit 11 outputs a control command to the display 2 to change the color of the operation state image 52a from the previous display color to blue, thereby changing the color of the operation state image 52a to blue. Blue represents the air blowing of the air-conditioned seat 32. For example, when the occupant touches the operation state image 52a a plurality of times, the display control unit 11 outputs a control command to the display 2 to increase the blue scale display in the positive z-axis direction so that the number of touches and the number of graduations of the scale display are linked. Thus, since the display mode of the operation state image 52a changes according to the operation of the occupant, the occupant can easily grasp the heat generation level of the seat heater 31 for the passenger seat or the air volume level of the air-conditioned seat 32 through vision. In particular, since the operation of the seat heater 31 is displayed in red and the operation of the air-conditioned seat 32 is displayed in blue, the occupant can intuitively grasp the operating device from the display color of the operation state image 52a, so that the visibility of the operation state image 52a can be enhanced. Note that the display mode of the operation state image 52a and the control method of the display mode described with reference to FIG. 4 are merely examples, and other display modes and control methods of the display mode may also be used.

[0040] Next, the temperature adjustment bar 54 will be described. As shown in FIG. 4, a temperature adjustment bar 54 is displayed on the left side of the seat image 52. The temperature adjustment bar 54 has an image of a line segment along the z-axis and a button display 54c that can be moved on the line segment. The upper end 54a of the image of the line segment is displayed in red, and the lower end 54b of the image of the line segment is displayed in blue. In FIG. 4, dots are used instead of colors. Similarly, dots are used instead of colors in the temperature adjustment bars shown in FIGS. 5 and 6. Also, the image of the line segment has a gradient display that changes from red to blue from the upper end 54a to the lower end 54b. The button display 54c on the line segment can be moved by a touch operation such as tapping, swapping, and / or flicking. When the button display 54c moves toward the upper end 54a of the line by a touch operation, the set temperature of the environment temperature control device 3 for the passenger seat in the auto mode increases. On the other hand, when the button display 54c moves toward the lower end 54b of the line segment by a touch operation, the set temperature of the environment temperature control device 3 for the passenger seat in the auto mode decreases. The set temperature of the environment temperature control device 3 for the passenger seat changes according to the position of the button display 54c included in the temperature adjustment bar 54. The temperature adjustment bar 54 is an adjustment icon for adjusting the set temperature in the space of the passenger seat. That is, when the temperature adjustment bar 54 is operated by an upward touch operation, the environment temperature control unit 12 outputs a control command to increase the set temperature of the environment temperature control device 3 for the passenger seat, and when the temperature adjustment bar 54 is operated by a downward touch operation, the environment temperature control unit 12 outputs a control command to decrease the set temperature of the environment temperature control device 3 for the passenger seat. Thereby, the occupant can easily change the set temperature of the environment temperature control device 3 for the passenger seat by a touch operation on the display 2. Also, since the upper end 54a and the lower end 54b of the temperature adjustment bar 54 are distinguished by red / blue, the occupant can easily grasp from the passenger seat setting screen in which direction to perform the touch operation to raise or lower the temperature.

[0041] Also, when the button display 54c included in the temperature adjustment bar 54 is operated by a directional touch operation, the unit of change in the set temperature may be changed according to the operation speed of the directional touch operation. The unit of change in the set temperature is preset in multiple steps, for example, preset to 0.5 °C, 1.0 °C, etc. When the moving speed of the button display 54c is equal to or lower than a predetermined speed threshold, the environmental temperature control unit 12 sets the unit of change in the set temperature (temperature change amount per unit) to the minimum unit (0.5 °C). When the moving speed of the button display 54c is greater than the predetermined speed threshold, the environmental temperature control unit 12 sets the unit of change in the set temperature (temperature change amount per unit) to a unit larger than the minimum unit (for example, 1.0 °C). For example, when the occupant operates the button display 54c by swiping, when the moving speed of the button display 54c by swiping is high, the change amount of the set temperature becomes larger with respect to the moving amount of the button display 54c by swiping. On the other hand, in the same touch operation by swiping, when the moving speed of the button display 54c is low, even if the moving amount of the button by swiping is the same, the change amount of the set temperature becomes smaller. That is, even if the moving amount of the button display 54c is the same, the change amount of the set temperature changes due to the difference in the moving speed. The greater the moving speed of the touch operation, the larger the unit of change in the set temperature, and thus the larger the change range of the set temperature. Thereby, the unit of change in the set temperature can be adjusted by the moving speed of the button display 54c by the directional touch operation, so that the temperature can be easily adjusted.

[0042] Next, the temperature display image 55 will be described. As shown in FIG. 4, the temperature display image 55 is displayed on the left side of the temperature adjustment bar 54. The temperature display image 55 has a temperature meter 55a, an up button display 55b, and a down button display 55c. The temperature meter 55a indicates the current set temperature. The up button display 55b is a button for increasing the set temperature, and the down button display 55c is a button for decreasing the set temperature. When the up button display 55b is touched once, the set temperature rises by a predetermined change unit (for example, 0.5 °C). When the down button display 55c is touched once, the set temperature drops by a predetermined change unit (for example, 0.5 °C). Also, the up button display 55b is displayed in red, and the down button display 56c is displayed in blue. Thus, the occupant can confirm the current set temperature and easily change the set temperature of the environmental temperature control device 3 for the passenger seat by a touch operation on the passenger seat setting screen 51. Also, since the up button display 55b and the down button display 56c are distinguished by red / blue, the occupant can easily grasp which button to touch to raise or lower the temperature from the passenger seat setting screen 51. Note that the object controlled by the set temperature on the temperature adjustment bar 54 and the temperature display image 55 only needs to be at least the air conditioner 34, and the seat heater 31 and the air-conditioned seat 32 may be excluded from the object.

[0043] The window that displays the passenger seat setting screen 51 is controlled by the display control unit 11 to close when a predetermined condition is satisfied. For example, when a certain period of time has elapsed after the display of the passenger seat setting screen 51 (when it times out), or when the area 41a of the home screen 41 is touched by the occupant, the display control unit 11 outputs a control command to close the passenger seat setting screen 51 and a control command to return the brightness of the home screen 41 to the state before the display of the passenger seat setting screen 51 to the display 2. As a result, the passenger seat setting screen 51 closes, and the home screen 41 shown in FIG. 3 is displayed on the display 2. While the passenger seat setting screen 51 is being displayed, the display of the home screen 41 is controlled by the display control unit 11 independently of the passenger seat setting screen 51. As shown in the example of FIG. 4, when the current location icon P is displayed on the home screen 41, the display control unit 11 outputs a control command to change the display position of the current location icon P according to the movement of the vehicle even after the display of the passenger seat setting screen 51 to the display 2. Thereby, the driver can drive while checking the navigation screen 45 before and after the display of the passenger seat setting screen 51.

[0044] Next, the driver's seat setting screen displayed on the display 2 when the occupant touches the driver's seat icon 42R shown in FIG. 3 will be described. When the occupant touches the driver's seat icon 42R, the display control unit 11 detects the position touched on the home screen 41 and recognizes that the detected position corresponds to the position of the driver's seat icon 42R. The touch operation on the driver's seat icon 42 includes a touch operation on the set temperature display 421R, a touch operation on the operation state display 422R, and a touch operation on the operation state display 423R. When a touch operation is performed on any of the set temperature display 421R, the operation state display 422R, or the operation state display 423R, the display control unit 11 recognizes that a touch operation has been performed on the driver's seat icon 42R. The display control unit 11 reads out the image data of the driver's seat setting screen described later from the memory. The display control unit 11 outputs a control command (second control command R) for displaying the image data read from the memory to the display 2. In the present embodiment, the second control command R includes a control command for displaying the driver's seat setting screen superimposed on the home screen 41. The second control command R also includes a control command for displaying the driver's seat setting screen at a position covering the driver's seat icon 42R. Further, similar to the passenger seat setting screen, when the current location icon P is displayed on the home screen 41, the second control command R includes a control command for displaying the current location icon P in the area of the home screen 41 where the driver's seat setting screen is not superimposed. The second control command R also includes a control command for reducing the brightness of the home screen 41 compared to before the driver's seat setting screen is displayed.

[0045] FIG. 5 is an example of a driver's seat setting screen 61 displayed on the display 2 when the driver's seat icon 42R in the home screen 41 shown in FIG. 3 is touch-operated. The driver's seat setting screen 61 is a screen for the occupant to set the seat temperature control device 30 of the driver's seat. The driver's seat setting screen 61 is displayed within a new window generated on the home screen 41. The driver's seat setting screen 61 is smaller than the home screen 41 and larger than the driver's seat icon 42R shown in FIG. 3. Note that the driver's seat setting screen 61 has the same size as the passenger seat setting screen 51 shown in FIG. 4. Also, the driver's seat setting screen 61 is located closer to the driver's seat side than the passenger seat on the display screen of the display 2. Further, the driver's seat setting screen 61 is displayed superimposed on the home screen 41 so as to cover the driver's seat icon 42R in the home screen 41. The home screen 41 has an area 41b that is not superimposed on the driver's seat setting screen 61. The brightness of the home screen 41 shown in FIG. 5 is lower than the brightness of the home screen 41 shown in FIG. 3. Note that, similar to the home screen 41 shown in FIG. 4, the absolute value of the brightness of the home screen 41 shown in FIG. 5 is not particularly limited as long as it is relatively lower than the brightness of the home screen 41 shown in FIG. 3. Due to the decrease in the brightness of the home screen 41, the driver's seat setting screen 61 is relatively emphasized, and it becomes easier for the occupant to check the display content of the driver's seat setting screen 61. Also, the current location icon P of the navigation screen 45 is displayed in the area 41b of the home screen 41. The current location icon P shown in FIG. 5 corresponds to the current location icon P shown in FIG. 3. Even when the driver's seat setting screen 61 is displayed, the driver can easily grasp the current location of the vehicle by the current location icon P.

[0046] The driver's seat setting screen 61 includes a seat image 62 representing the driver's seat, a main switch button display 63a, a mode switch button display 63b, a seat heater button display 63c, an air-conditioned seat button display 63d, a temperature adjustment bar 64, a temperature display image 65, a steering wheel heater button display 66, and a synchronization switch button display 67. Among these button displays, bars, and images, those excluding the synchronization switch button display 67 are displays through which the occupant can input control items related to the temperature control of the driver's seat. The seat image 62 is displayed by rotating counterclockwise by a predetermined angle (for example, in the range of 10 degrees to 45 degrees) around the z-axis and in the forward direction of the vehicle with respect to the actual driver's seat. The main switch button display 63a is a button display for switching on and off the seat temperature control device 30 of the driver's seat by a touch operation. The mode switch button display 63b is a display for switching the operation mode (auto mode / manual mode) of the seat temperature control device 30 of the driver's seat. The seat heater button display 63c is a display for switching on and off the seat heater 31 by a touch operation. The air-conditioned seat button display 63d is a display for switching on / off the air-conditioned seat 32 by a touch operation. The steering wheel heater button display 66 is displayed between the seat image 62 and the temperature adjustment bar 64 and is a display for switching on / off the steering wheel heater 33 by a touch operation. Some or all of these button displays are superimposed on the seat image 62 and displayed. On the driver's seat setting screen 61, each button display excluding the steering wheel heater button display 66 and the synchronization switch button display 67 is arranged symmetrically with respect to the z-axis with respect to the arrangement of each button display on the passenger seat setting screen 51. Also, the driver's seat setting screen 61 is different from the passenger seat setting screen 51 shown in FIG. 4 in that it includes the steering wheel heater button display 66 and the synchronization switch button display 67. The steering wheel heater button display 66 is not displayed on the passenger seat setting screen 51 shown in FIG. 4. Regarding the configuration common to the passenger seat setting screen 51, the description in FIG. 4 is incorporated by reference.

[0047] Next, the synchronous switch button display 67 will be described. The synchronous switch button display 67 is a display that can synchronize the operation of the seat temperature control device 30 of the driver's seat and the operation of the seat temperature control device 30 of the passenger seat. When the synchronous switch button display 67 is on, the occupant can, by operating the display content of the driver's seat setting screen 61, not only operate the seat temperature control device 30 of the driver's seat but also operate the seat temperature control device 30 of the passenger seat. For example, in a situation where the passenger in the passenger seat is sleeping or otherwise unable to operate the passenger seat setting screen 51, the driver can turn on the synchronous switch button display 67 and operate the seat temperature control device 30 of the passenger seat. To prevent the driver from touching the passenger seat icon 42L (see FIG. 3) and operating the seat temperature control device 30 of the passenger seat from the passenger seat setting screen 51 (see FIG. 4), the driver can easily operate the seat temperature control device 30 of the passenger seat. In particular, to prevent the driver during driving from being forced to perform unnecessary operations, the burden on the driver can be reduced. On the other hand, when the synchronous switch button display 67 is off, the occupant can only operate the seat temperature control device 30 of the driver's seat by operating the display content of the driver's seat setting screen 61, and cannot operate the seat temperature control device 30 of the passenger seat. Since the steering heater 33 is provided only on the driver's seat, regardless of whether the synchronous switch button display 67 is on or off, the occupant operates the steering heater 33 from the steering heater button display 66.

[0048] The window that displays the driver's seat setting screen 61 is controlled by the display control unit 11 to close when a predetermined condition is satisfied. For example, when a certain period of time has elapsed after the display of the driver's seat setting screen 61 (when a timeout occurs), or when the area 41b of the home screen 41 is touched by the occupant, the display control unit 11 outputs a control command to close the driver's seat setting screen 61 and a control command to return the brightness of the home screen 41 to the state before the display of the driver's seat setting screen 61 to the display 2. As a result, the driver's seat setting screen 61 closes, and the home screen 41 shown in FIG. 3 is displayed on the display 2. Note that while the driver's seat setting screen 61 is being displayed, the display of the home screen 41 is controlled by the display control unit 11 independently of the driver's seat setting screen 61, in the same manner as when the passenger seat setting screen 51 is being displayed.

[0049] Next, the air-conditioning setting screen displayed on the display 2 when the occupant touches the air-conditioning icon 431 shown in FIG. 3 will be described. When the occupant touches the air-conditioning icon 431, the display control unit 11 detects the position touched on the home screen 41 and recognizes that the detected position corresponds to the position of the air-conditioning icon 431. The display control unit 11 reads out the image data of the air-conditioning setting screen, which will be described later, from the memory. The display control unit 11 outputs a control command (third control command) for displaying the image data read from the memory to the display 2. The third control command is a control command for switching the display screen of the display 2 from the home screen 41 to the air-conditioning setting screen.

[0050] FIG. 6 is an example of the air-conditioning setting screen 71 displayed on the display 2 when the air-conditioning icon 431 within the home screen 41 shown in FIG. 3 is touched. The air-conditioning setting screen 71 is a screen for the occupant to set the air-conditioning equipment 34. The air-conditioning setting screen 71 has the same size as the home screen 41 shown in FIG. 3, and unlike the examples in FIGS. 4 and 5, the home screen 41 is not displayed on the display 2 when the air-conditioning setting screen 71 is displayed.

[0051] The air - conditioning setting screen 71 includes a seat image 72 representing the passenger seat, a seat image 73 representing the driver's seat, a main switch button display 74, a mode switch button display 75, a steering - heater button display 76, a rear - seat icon 77, temperature adjustment parts 78R and 78L, a synchronization switch button display 79, and a return icon 80. Although detailed explanations are omitted, between the seat image 72 and the seat image 73, there are button displays, icons, etc. that allow the occupant to operate the air volume and air direction of the air - conditioning equipment 34. By operating the button displays, icons, etc. arranged between the seat image 72 and the seat image 73, or the temperature adjustment parts 78R and 78L, the occupant can operate at least one of the air volume, air direction, and set temperature of the air - conditioning equipment 34 for the passenger seat and the driver's seat.

[0052] The main switch button display 74 is a button display for switching the on / off of the air - conditioning equipment 34 by touch operation. The mode switch button display 75 is a button display for switching the operation mode (auto mode / manual mode) of the air - conditioning equipment 34. The steering - heater button display 76 is a button display for switching the on / off of the steering heater 33 by touch operation. The rear - seat icon 77 is an icon for displaying a rear - seat setting screen described later. The temperature adjustment part 78R is a display for adjusting the temperature of the seat space on the driver's - seat side, and the temperature adjustment part 78L is a display for adjusting the temperature of the seat space on the passenger - seat side. Since the temperature adjustment part 78R and the temperature adjustment part 78L are each composed of a temperature - adjustment bar similar to the temperature - adjustment bar 54 in FIG. 4 (temperature - adjustment bar 64 in FIG. 5) and a temperature - display image similar to the temperature - display image 55 in FIG. 4 (temperature - display image 65 in FIG. 5), the description of the operation method, etc. is incorporated by reference to the above - mentioned explanation. The synchronization switch button display 79 is a switch for synchronously adjusting the driver - seat air flow from the air - conditioning equipment 34 to the driver's seat and the passenger - seat air flow from the air - conditioning equipment 34 to the passenger seat. The return icon 80 is a screen for returning the display screen of the display 2 to the screen before the air - conditioning setting screen 71 is displayed.

[0061] Next, an explanation will be given of the rear seat setting screen that is displayed on the display 2 when the occupant touches the rear seat icon 77 shown in FIG. 6. When the occupant touches the rear seat icon 77, the display control unit 11 detects the position touched on the air conditioning setting screen 71 and recognizes that the detected position corresponds to the position of the rear seat icon 77. The display control unit 11 reads out the rear seat setting screen, which will be described later, from the memory. The display control unit 11 outputs a control command (fifth control command) for causing the image data read from the memory to be displayed to the display 2. The fifth control command includes a control command for reducing the brightness of the air conditioning setting screen 71 as compared to before the rear seat setting screen is displayed.

[0062] FIG. 9 is an example of the rear seat setting screen 101 that is displayed on the display 2 when the rear seat icon 77 within the air conditioning setting screen 71 shown in FIG. 6 is touched. The rear seat setting screen 101 is a screen for the occupant to set the seat temperature control device 30 of the rear seat. The rear seat setting screen 101 is the same size as the air conditioning setting screen 71 shown in FIG. 6.

[0063] The rear seat setting screen 101 includes a seat image 102 representing the rear seat, a front seat icon 103, and a return icon 104. The seat image 102 includes operation state images 102a, 102b representing the operation states of the seat temperature control devices 30 of the rear seat. The number of operation state images 102a, 102b displayed corresponds to the number of seat temperature control devices 30 of the rear seat. The rear seat setting screen 101 in FIG. 9 indicates that two seat temperature control devices 30 are provided for the rear seat. In the operation state image 102a, an image representing the seat heater 31 or an image representing the air-conditioned seat 32 switches according to the device in operation. Since the display mode of the operation state image 102a corresponds to the display mode of the operation state image 72a shown in FIG. 6, the above description is incorporated by reference. Also, in the operation state image 102b, similar to the operation state image 52a described in FIG. 4, the display color switches to red representing the heat generation of the seat heater 31 or blue representing the air blowing of the air-conditioned seat 32 according to the device in operation. The driver or the front passenger can control the seat temperature control device 30 of the rear seat by touching the operation state image 102b. In the example of FIG. 9, although two operation state images 102a, 102b are displayed, for a touch operation on one of them, the two seat temperature control devices 30 provided for the rear seat may operate in conjunction, or the two seat temperature control devices 30 provided for the rear seat may operate individually for each of the operation state images 102a, 102b.

[0064] The front seat icon 103 is an icon for returning the display screen of the display 2 to the air-conditioning setting screen 71 shown in FIG. 6. When the occupant touches the front seat icon 103, the display control unit 11 outputs a control command for returning the display screen to the air-conditioning setting screen 71 to the display 2. The return icon 104 is a screen for returning the display screen of the display 2 to the screen before the rear seat setting screen 101 is displayed. When the return icon 104 is touched, the display control unit 11 outputs a control command for returning the display screen to the screen before the rear seat setting screen 101 is displayed to the display 2.

[0065] As described above, in the environmental temperature control system 1 according to the present embodiment, the display control device controls the display screen of the touch panel type display 2 that can be touched and operated by the occupant from the driver's seat and the front passenger seat of the vehicle. The display control device includes a controller 10 that controls the display screen of the display 2 based on the touch operation of the occupant on the display 2. The controller 10 outputs a first control command for displaying a home screen 41 including a front passenger seat icon 42L associated with the front passenger seat and a driver's seat icon 42R associated with the driver's seat. When one of the seat icons of the front passenger seat icon 42L and the driver's seat icon 42R is operated, a second control command (second control command L or second control command R) for displaying a setting screen (front passenger seat setting screen 51 or driver's seat setting screen 61) of one of the seats of the front passenger seat icon 42L and the driver's seat icon 42R is output. The front passenger seat setting screen 51 includes a display (seat image 52, main switch button display 53a, mode switch button display 53b, seat heater button display 53c, air-conditioned seat button display 53d, temperature adjustment bar 54, temperature display image 55) in which the user can input control items related to the temperature control of the front passenger seat, and is located on the display screen closer to the front passenger seat side than the driver's seat. The driver's seat setting screen 61 includes a display (seat image 62, main switch button display 63a, mode switch button display 63b, seat heater button display 63c, air-conditioned seat button display 63d, temperature adjustment bar 64, temperature display image 65) in which the user can input control items related to the temperature control of the driver's seat, and is located on the display screen closer to the driver's seat side than the front passenger seat. As a result, it becomes easier for the front passenger to reach the front passenger seat setting screen 51 from the front passenger seat, and it becomes easier for the driver to reach the driver's seat setting screen 61 from the driver's seat. Therefore, even when the driver is sitting in the seat, the operability can be improved. In addition, it becomes easier for the front passenger to check the operating state of the seat temperature control device 30 of the front passenger seat, and it becomes easier for the driver to check the operating state of the seat temperature control device 30 of the driver's seat. Therefore, the visibility of the operating state of the seat temperature control device 30 can be improved.

[0066] Also, in the present embodiment, the second control command L includes a control command for causing the passenger seat setting screen 51 to be displayed superimposed on the home screen 41, and the second control command R includes a control command for causing the driver's seat setting screen 61 to be displayed superimposed on the home screen 41. Thereby, the occupant can intuitively recognize that the passenger seat setting screen 51 or the driver's seat setting screen 61 is displayed. In particular, even when the driver is driving and looking straight ahead at the front of the vehicle, the driver can recognize that the passenger seat setting screen 51 is displayed in the peripheral vision, making it easier to recognize the fact that the passenger in the passenger seat has operated.

[0067] Also, in the present embodiment, the temperature control of the driver's seat or the passenger seat includes the temperature control of at least one of the seat heater 31 and the air-conditioned seat 32 provided in the vehicle. Thereby, the occupant can easily grasp the operating state of the seat temperature control device 30 of the driver's seat or the passenger seat from the display content of the passenger seat setting screen 51 or the driver's seat setting screen 61.

[0068] Also, in the present embodiment, the passenger seat setting screen 51 and the driver's seat setting screen 61 are smaller than the home screen 41 and larger than the passenger seat icon 42L and the driver's seat icon 42R. Thereby, the occupant can confirm the display content of the home screen 41 displayed behind the passenger seat setting screen 51 or the driver's seat setting screen 61, so that the occupant can grasp the display content of the home screen 41 before and after the passenger seat setting screen 51 or the driver's seat setting screen 61 is displayed. Also, since the passenger seat setting screen 51 and the driver's seat setting screen 61 are larger than the passenger seat icon 42L and the driver's seat icon 42R, the visibility of the passenger seat setting screen 51 and the driver's seat setting screen 61 can be enhanced.

[0069] Also, in the present embodiment, the home screen 41 includes map information in its display content. Thereby, the driver can drive while checking the map information before and after the passenger seat setting screen 51 or the driver's seat setting screen 61 is displayed.

[0070] Also, in the present embodiment, when the current location icon P indicating the current location of the vehicle is displayed on the home screen 41, the second control command L includes a control command to display the current location icon P in the area 41a of the home screen 41 where the passenger seat setting screen 51 is not superimposed. Also, in the present embodiment, when the current location icon P is displayed on the home screen 41, the second control command R includes a control command to display the current location icon P in the area 41b of the home screen 41 where the driver's seat setting screen 61 is not superimposed. Thereby, the driver can drive while checking the current location of the vehicle before and after the passenger seat setting screen 51 or the driver's seat setting screen 61 is displayed.

[0071] Also, in the present embodiment, the second control command L includes a control command to lower the brightness of the home screen 41 compared to before the passenger seat setting screen 51 is displayed. Also, in the present embodiment, the second control command R includes a control command to lower the brightness of the home screen 41 compared to before the driver's seat setting screen 61 is displayed. Thereby, the passenger seat setting screen 51 or the driver's seat setting screen 61 can be relatively emphasized and displayed, and the occupant can easily grasp the display content of the passenger seat setting screen 51 or the driver's seat setting screen 61. Also, even after the passenger seat setting screen 51 or the driver's seat setting screen 61 is displayed, the occupant can confirm the display content of the home screen 41.

[0072] Also, in the present embodiment, the passenger seat setting screen 51 does not include a display related to the temperature control of the driver's seat. Also, in the present embodiment, the driver's seat setting screen 61 does not include a display related to the temperature control of the passenger seat. Thereby, since the number of display contents of each setting screen can be reduced, each setting screen can be minimized. As a result, as shown in FIG. 4 or FIG. 5, the occupant can check the display content of the home screen 41 displayed behind the passenger seat setting screen 51 or the driver's seat setting screen 61 while operating the seat temperature control device 30.

[0073] Also, in the present embodiment, the passenger seat setting screen 51 does not include a display related to the steering heater 33, and the driver's seat setting screen 61 includes a steering heater button display 66 related to the steering heater 33. Thereby, it is possible to prevent the passenger from confusing the passenger seat setting screen 51 and the driver's seat setting screen 61, and the passenger can easily understand whether they can operate either the seat temperature control device 30 for the passenger seat or the seat temperature control device 30 for the driver's seat.

[0074] Also, in the present embodiment, the passenger seat setting screen 51 includes an operation state image 52a in which the operation states of the seat heater 31 and the air-conditioned seat 32 are displayed in different colors. Also, in the present embodiment, the driver's seat setting screen 61 includes an operation state image 62a in which the operation states of the seat heater 31 and the air-conditioned seat 32 are displayed in different colors. Thereby, the passenger can easily grasp which device, the seat heater 31 or the air-conditioned seat 32, the operation state image represents.

[0075] Also, in the present embodiment, the operation state images 52a and 62a are images representing the heat generation level of the seat heater 31 or the air volume level of the air-conditioned seat 32 based on the difference in the number of graduations. Thereby, the passenger can easily grasp the heat generation level of the seat heater 31 or the air volume level of the air-conditioned seat 32, and can easily grasp the operation state of the seat temperature control device 30.

[0076] Also, in the present embodiment, the home screen 41 includes an air-conditioning icon 431 associated with the air-conditioning equipment 34 mounted on the vehicle. When the air-conditioning icon 431 is operated, the controller 10 outputs a third control command to switch the display from the home screen 41 to the air-conditioning setting screen 71. The air-conditioning setting screen 71 includes a display that allows the occupant to input control items related to the air-conditioning control of the passenger seat and the driver's seat. As a result, without providing mechanical buttons, dials, etc. for operating the air-conditioning equipment 34 separately from the display 2 in the vehicle, the occupant can operate the air-conditioning equipment 34. As a result, the number of components mounted on the vehicle can be reduced, and the degree of freedom in layout design can be increased. Also, by reducing the number of components, a display 2 with a larger number of inches can be mounted, and the operability and visibility of the display screen can be improved.

[0077] Also, in the present embodiment, the air-conditioning icon 431 is located on the home screen 41 closer to the driver's seat than the passenger seat. As a result, it becomes easier for the driver's hand to reach the air-conditioning icon 431 from the driver's seat, and the driver can easily display the air-conditioning setting screen 71, improving the operability of the air-conditioning setting screen 71. As a result, the load on the driver during driving can be reduced.

[0078] Also, in the present embodiment, the control items related to air-conditioning control include at least any one of the air volume, air direction, and set temperature of the air-conditioning equipment 34 for the passenger seat and the driver's seat. As a result, for example, even in a situation where the display 2 cannot be operated, such as when the passenger in the passenger seat is sleeping during vehicle travel, the driver can perform an operation considering the passenger in the passenger seat who cannot operate the display 2, such as reducing the air volume to the passenger seat.

[0079] Also, in the present embodiment, the air-conditioning setting screen 71 includes operation state images 72a, 72b, 73a, 73b representing the heating level of the seat heater 31 provided in the passenger seat and the driver's seat or the air volume level of the air-conditioned seat 32. Thereby, the passenger can grasp not only the operation state of the air-conditioning equipment 34 but also the operation state of the seat temperature control equipment 30 for the passenger seat and the driver's seat. Since the driver can grasp the operation state of each device on one screen, the load on the driver during driving can be reduced.

[0080] Note that the embodiments described above are described to facilitate the understanding of the present invention and are not described to limit the present invention. Therefore, each element disclosed in the above embodiments is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

[0081] For example, in the above-described embodiment, a right-hand drive vehicle is taken as an example for explanation, but the display control device and the display control method of the present invention can also be applied to a left-hand drive vehicle. Although detailed description is omitted, the arrangement of the passenger seat icon and the driver's seat icon on the home screen and the display positions of the passenger seat setting screen and the driver's seat setting screen may be changed according to the left-right arrangement relationship between the driver's seat and the passenger seat.

[0082] Also, for example, in the above-described embodiment, an operation state image representing the heating level of the seat heater 31 or the air volume level of the air-conditioned seat 32 by the number of graduations is taken as an example for explanation, but the method of representing the heating level of the seat heater 31 or the air volume level of the air-conditioned seat 32 may be other methods. For example, an operation state image in which the size of the image changes according to the heating level of the seat heater 31 or the air volume level of the air-conditioned seat 32 may be used. The operation state image may be an image representing the heating level of the seat heater 31 or the air volume level of the air-conditioned seat 32 due to differences in the size or number of figures.
