And a control means (10) for controlling the shut-off state.

  According to the present invention, when the driver's seat air conditioning command is given by the occupant operating the input means without being based on the detection result of the detection means, the air conditioning range of the blowing state variable means is centered on the driver's seat. Since the air conditioning is performed and the opening / closing means is controlled to be in the shut-off state, the air conditioning capability of the remaining seats other than the driver's seat can be used for air conditioning of the driver's seat. Moreover, since air is sucked in from the inside air inlet opening below the driver's seat, it is possible to create a conditioned air circulation only in the driver's seat space. Therefore, the driver's seat space can be efficiently air-conditioned.

  Further, when the driver's seat air conditioning command is given by the input means, the air conditioning is performed mainly on the driver's seat as described above. Therefore, even if there are other passengers in the passenger seat and the rear seat, for example, When an occupant dislikes air conditioning, or when another occupant does not need air conditioning due to poor physical condition or the like, only the driver's seat can be air-conditioned by operating the input means. Therefore, the driver can execute spot air conditioning in the so-called driver's seat space at a desired timing and by an operation using simple input means.

A coupling member (86) that mechanically connects the operation piece and each blowing state variable means, and interlocks so as to change the open / close state and air conditioning range of the blowing state variable means according to the position of the operation piece,
When the operation piece is disposed at the first position, a positioning force is applied to each blowing state varying means, and the air outlets (30) that have the remaining seats excluding the vehicle driver's seat among the plurality of air outlets. To 33) are closed, and the blowing state variable means provided at the air outlets (20 to 23) having the driver's seat as the air conditioning range are opened, and the air conditioning range of the open air outlets The air conditioner for the vehicle is characterized in that the air conditioning range of the blowing state varying means is changed so as to air-condition the driver seat.

  According to the present invention, by moving the operation piece to the first position, the blowing state variable means is interlocked, and the air conditioning range of the blowing state varying means for air conditioning the driver's seat is air-conditioned centering on the driver's seat. The remaining blowing state variable means is closed. As a result, the air conditioning capacity of the remaining seats other than the driver's seat can be used for air conditioning of the driver's seat. Moreover, since the inside air suction opening opened below the driver's seat is provided, the air-conditioning air circulation only in the driver's seat space can be created by sucking air from the inside air suction opening. Therefore, the driver's seat space can be efficiently air-conditioned.

The present invention further includes an input means (65) for inputting a driver seat air conditioning command for air conditioning the driver's seat;
It further includes a drive unit (81) for displacing the operation piece from the second position to the first position when a driver's seat air conditioning command is given.

  According to the present invention, when the driver's seat air conditioning command is input by the input means, the operation piece is displaced from the second position to the first position by the drive unit, so that the occupant himself does not need to give positioning force to the operation piece. . Accordingly, the occupant can place the operation piece at the first position with a simple operation.

The single-passenger eco mode switch 65 is an input means for requesting to set the suction / blowing mode to a single-passenger eco mode, which will be described later, according to the manual operation of the occupant.

  The air conditioner ECU 10 has a known configuration including functions such as a CPU (central processing unit) that performs arithmetic processing and control processing, a memory such as a ROM and a RAM, and an I / O port (input / output circuit). A microcomputer is provided. Sensor signals from various sensors are A / D converted by an I / O port or an A / D conversion circuit and then input to a microcomputer. The air conditioner ECU 10 includes an inside air temperature sensor 71 as an inside air temperature detecting means for detecting a vehicle interior temperature (inside air temperature) Tr, an outside air temperature sensor 72 as an outside air temperature detecting means for detecting a vehicle outside temperature (outside air temperature), and solar radiation. A solar radiation sensor 73 is connected as detection means. Further, the air conditioner ECU 10 detects the air temperature immediately after passing through the evaporator 41 (post-evaporation temperature TE), a post-evaporation temperature sensor 74 as a post-evaporation temperature detection means, detects the engine coolant temperature of the vehicle, and heats the blown air. A cooling water temperature sensor 75 as a heating temperature detection means for temperature, a humidity sensor 76 as a humidity detection means for detecting the relative humidity in the passenger compartment, a seating sensor 77 as an occupant detection means for detecting the presence or absence of an occupant in each seat, and the like Is connected.

  For the inside air temperature sensor 71, the outside air temperature sensor 72, the post-evaporation temperature sensor 74, and the cooling water temperature sensor 75, for example, temperature sensitive elements such as thermistors are used. Further, the solar radiation sensor 73 includes a driver-seat-side solar radiation intensity detecting means for detecting a solar radiation amount (solar radiation intensity) irradiated in the driver-seat-side air-conditioned space, and a solar radiation amount (solar radiation intensity) irradiated in the passenger seat-side air-conditioned space For example, a photodiode is used. The humidity sensor 76 is housed in a recess formed in the front surface of the instrument panel 50 in the vicinity of the driver's seat together with the inside air temperature sensor 71, and determines whether or not a defroster blowout is necessary for anti-fogging of the front window glass. Used.

  Next, a control method by the air conditioner ECU 10 will be described with reference to FIG. FIG. 10 is a flowchart showing an example of a control program of the air conditioner ECU 10. First, when the ignition switch is turned on and DC power is supplied to the air conditioner ECU 10, the control program shown in FIG. 10 stored in advance in the memory is executed.

  In step a1, the stored contents of the data processing memory built in the microcomputer inside the air conditioner ECU 10 are initialized, and the process proceeds to step a2. In step a2, various data are read into the data processing memory, and the process proceeds to step a3. Accordingly, in step a2, switch signals from various operation switches on the air conditioner operation panel 51 and sensor signals from various sensors are input. As sensor signals, for example, the interior temperature Tr detected by the internal air temperature sensor 71, the external air temperature Tam detected by the external air temperature sensor 72, the solar radiation amount Ts detected by the solar radiation sensor 73, and the post-evaporation temperature Te detected by the post-evaporation sensor 74 are included. And the cooling water temperature Tw detected by the cooling water temperature sensor 75.

  In step a3, the input data is substituted into the stored arithmetic expression to calculate the target blowing temperature TAO (Dr) on the driver's seat side and the target blowing temperature TAO (Pa) on the passenger seat side. Then, the target post-evaporator temperature TEO is calculated from the target blowing temperatures TAO (Dr) and TAO (Pa) on the passenger seat side and the outside air temperature Tam, and the process proceeds to step a4. In step a4, the blower air volume, that is, the blower control voltage VA to be applied to the blower motor 9 is calculated based on the calculated target blow temperature TAO (Dr), TAO (Pa) on the driver's seat and passenger's side, and the flow proceeds to step a5. . For the blower control voltage VA, the blower control voltages VA (Dr) and VA (Pa) respectively adapted to the target blowing temperatures TAO (Dr) and TAO (Pa) on the driver's seat side and the passenger seat side are set in a predetermined characteristic pattern. It is obtained by averaging these blower control voltages VA (Dr) and VA (Pa).

  In step a5, the calculated target blowing temperatures TAO (Dr) and TAO (Pa) on the driver's seat side and the passenger's seat side and the input data in step a2 are substituted into the arithmetic expression stored in the memory to drive the vehicle. The A / M opening degree SW (Dr) (%) of the seat side A / M door 15 and the A / M opening degree SW (Pa) (%) of the passenger side A / M door 16 are calculated, and the process proceeds to step a6. Move. In step a6, based on the target blowing temperature TAO (Dr) and TAO (Pa) on the driver seat side and the passenger seat side calculated in step a3, the air flow suction mode to be taken into the passenger compartment and the air to be blown into the passenger compartment. The flow blowing mode is determined, and the process proceeds to step a7.

  In step a7, the target outlet temperatures TAO (Dr) and TAO (Pa) calculated in step a3 coincide with the actual post-evaporator temperature Te detected by the post-evaporation sensor 74. Then, a control current value for setting the compressor to the target discharge amount is determined by feedback control (PI control), and the process proceeds to step a8. Specifically, the solenoid current (control current: In), which is the target value of the control current supplied to the electromagnetic solenoid of the electromagnetic capacity control valve attached to the compressor, is calculated based on the arithmetic expression stored in the memory. To do.

  In step a8, a control signal is output to the blower drive circuit 8 so that the blower control current VA calculated in step a4 is obtained, and the process proceeds to step a9. In step a9, a control signal is output to the servomotors 17 and 18 so that the A / M opening degree SW (Dr), SW (Pa) determined in step a5 is obtained, and the process proceeds to step a10. In step a10, a control signal is output to the servomotors 28, 29, 38, 39 so that the suction mode and the blowing mode determined in step a6 are obtained, and the process proceeds to step a11.

  In step a11, the solenoid current (control current: In) determined in step a7 is output to the electromagnetic solenoid of the electromagnetic capacity control valve attached to the compressor, the process returns to step a2, and the processes from step a2 to step a11 are performed. repeat. By repeating such a series of processes, the passenger compartment temperature set by the passenger can be obtained.

  Next, an example of control related to the single passenger eco mode by the air conditioner ECU 10 will be described with reference to FIG. FIG. 11 is a flowchart showing an example of a control program of the air conditioner ECU 10 in the single passenger eco mode. The process shown in FIG. 11 is a subroutine provided between step a7 and step a8 in FIG. Accordingly, the process proceeds from step a7 in FIG. 10 to step b1 in FIG. 11. In step b1, it is determined from the signal corresponding to the presence or absence of the occupant in each seat detected by the seating sensor 77 whether or not the occupant is only the driver. Move to b2. If there are passengers other than the driver, the process proceeds to step a8 in FIG. 10 and normal air-conditioning control is performed as described above. If the passenger is only the driver, the process proceeds to step b2.

  In step b2, since the occupant is only the driver, the suction blow mode is changed to “one-seater eco mode” as a mode for rapidly adjusting the temperature of the driver's seat space, and the process proceeds to step a8. Specifically, the suction mode is set to the inside air mode, and the inside / outside air switching door 3 opens the inside air suction port 6 below the driver's seat side. Further, the air outlets 30 and 33 that are opened only in the passenger seat side air-conditioned space without passengers are all closed by the corresponding doors 34 and 36. Further, the direction of the louver 80 provided at the air outlets 21, 22, 31 opened in the driver side air conditioning space is changed by displacing the operation piece 81 a to the first position so that air conditioning is performed around the driver seat. Change the air conditioning range. Further, the opening / closing state of the duct opening / closing door 91 is switched from the open state to the closed state by displacing the operation piece 81a to the first position, so that the passenger side side face outlet 32 is closed.

  When the air conditioning mode is the cooling mode, the cold air is used as the bi-level air blowing mode in which both the face air outlets 21, 22, 31 and the foot air outlet 23 are opened at the doors 24 to 26 on the driver's seat side. Make a speech bubble. When the air conditioning mode is the heating mode, hot air blowing is performed as a foot blowing mode in which only the foot outlet 23 is opened at each of the doors 24 to 26 on the driver's seat side. Moreover, the blowing mode during heating may be the same bi-level blowing mode as during cooling. As a result, the conditioned air is blown only to the driver's seat space, so that the driver's seat space can be brought close to the set temperature efficiently.

  Accordingly, the air conditioner ECU 10 can set a mode in which the temperature of the driver's seat space is rapidly adjusted when it is determined from the detection result of the seating sensor 77 that only the driver is a driver. Specifically, among the plurality of outlets 20 to 23 and 30 to 33, the outlets 30, 31, and 33 that are opened outside the driver's seat space are all shut off at the corresponding doors 34, 36, and 91. The air-conditioning operation is performed by changing the air-conditioning space of the air outlets 21, 22, 31 opened in the driver's seat space to the driver's seat space and using the suction mode as the inside air mode. As a result, the conditioned air is blown out only to the driver seat space, so that the driver seat space can be brought close to the set temperature efficiently. Moreover, since only the driver's seat space is air-conditioned, the power required for air-conditioning can be reduced.

  Next, another example of the control related to the single passenger eco mode by the air conditioner ECU 10 will be described with reference to FIG. FIG. 12 is a flowchart showing another example of a control program of the air conditioner ECU 10 in the single passenger eco mode. The process shown in FIG. 12 is a process performed in parallel with the process of FIG. 11 described above, and is a subroutine provided between step a7 and step a8 of FIG. Accordingly, the process proceeds from step a7 in FIG. 10 to step c1 in FIG. 12, and in step c1, it is determined whether or not a single passenger eco mode switch 65, which is one of various operation switches on the air conditioner operation panel 51, has been operated by the occupant. If it is operated, the process proceeds to step c2. When the single passenger eco mode switch 65 is operated in step c1, a driver seat air conditioning command is given to the air conditioner ECU10. In step c2, since the driver's seat air conditioning command is given, the mode for rapidly adjusting the temperature of the driver's seat space is changed to the single passenger eco mode as in step b2 described above, and the process proceeds to step a8.

  As a result, the air conditioner ECU 10 can set a mode in which the temperature of the driver's seat space is rapidly adjusted when the one-seater eco mode switch 65 that is an input means for inputting a driver's seat air conditioning command is operated. Therefore, the same effect as the air conditioning effect of the driver's seat space described with reference to FIG. 11 described above can be achieved.

  As described above, the vehicular air conditioner 100 according to the present embodiment changes the direction of the louver 80 of the air outlets 21, 22, 31 for air-conditioning the driver's seat space when it is determined as the single passenger eco mode. Then, the air conditioning range is controlled so that the driver's seat is the center, and the doors 34, 36, 91 corresponding to the remaining outlets 30, 31, 33 are controlled to be closed, so that the remaining portions other than the driver's seat are excluded. The air conditioning capacity to the seat can be used for air conditioning of the driver's seat. Moreover, since air is sucked in from the inside air inlet 6 that opens below the driver's seat, it is possible to create an air-conditioning air circulation only in the driver's seat space. Therefore, the driver's seat space can be efficiently air-conditioned. As described above, since the air conditioning can be performed by concentrating only the driver's seat with a simple configuration, the vehicle air conditioner 100 capable of reducing the manufacturing cost can be provided.

  Further, in the present embodiment, as shown in FIG. 12, the driver's seat air conditioning command can be input by the single passenger eco mode switch 65, so that the occupant can drive using the single passenger eco mode switch 65 only when desired. The seats can be concentrated and air-conditioned. This can improve convenience.

  Furthermore, in the present embodiment, as shown in FIG. 11, when it is determined that there is a passenger only in the driver's seat based on the detection result of the seating sensor 77, the one-seater eco mode is set. The air conditioning can be concentrated. This can further improve convenience.

  Further, in the present embodiment, by moving the operation piece 81a to the first position, the four louvers 80 work together, and the air conditioning range of the louver 80 for air conditioning the driver's seat is air-conditioned around the driver's seat. Position. As a result, the air conditioning capacity of the remaining seats other than the driver's seat can be used for air conditioning of the driver's seat.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. In this embodiment,
Instead of the opening / closing door 91 in the duct according to the first embodiment, the opening / closing door 92 is provided in the opening of the air conditioning unit 1 communicating with the passenger side side face outlet 32. FIG. 13 is a view for explaining the operation of the louver 80 provided at the face outlets 21, 22, and 31 and the operation of the in-unit opening / closing door 92.

  The in-unit opening / closing door 92 is an opening of the air conditioning unit 1 and is provided in an opening that communicates with the passenger seat side face outlet 32 through the outlet duct. The in-unit open / close door 92 extends from an opening of the air-conditioning unit 1 through an air outlet duct into an open state that allows air-conditioning air to be blown to the passenger seat side face outlet 32 and a closed state that blocks air-conditioning air from being blown out. Switch. The intra-unit opening / closing door 92 is driven by an actuator such as a servo motor 81, and is driven by a servo motor 81 that drives the louver 80 in this embodiment.

  The in-unit open / close door 92 includes a door main body 92a, a spring member 85, and a wire 86. The in-unit open / close door 92 includes a door main body 92a formed in a plate shape, and is configured as a butterfly door in which a rotation shaft 92b is provided in an intermediate portion of the door main body 92a in the door width direction. A seal material (not shown) made of, for example, a rubber-based elastic material is arranged in a frame shape on the outer peripheral edge portion of the door main body 91a in order to improve adhesion with the inner wall of the blowout duct. One end of the door main body 92 a in the door width direction is connected to the servo motor 81 by a wire 86. The other end of the door main body 92a in the door width direction is connected to one end of the spring member 85.

  Therefore, the open / close state of the in-unit open / close door 92 is changed according to the position of the operation piece 81a. The state in which the operation piece 81a is in the first position is the single passenger eco mode, and the blowing direction by each louver 80 is set so that the driver's seat space is at the center. Further, when the operation piece 81a is in the first position, the in-unit open / close door 92 is set to be closed. Therefore, the three louvers 80 and the in-unit open / close door 92 can be operated simultaneously by one servo motor 81.

  As described above, in the present embodiment, when it is determined that the one-seater eco mode is set as in the first embodiment, the direction of the louver 80 of the outlets 21, 22, and 31 for air conditioning in the driver's seat space is changed. The air conditioning range is changed so that the driver's seat is at the center, and the doors 34, 36, and 92 corresponding to the remaining outlets 30, 31, and 33 are all closed. The air conditioning capacity of the driver's seat can be used for air conditioning of the driver's seat. Therefore, the same operations and effects as those of the first embodiment described above can be achieved.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. The present embodiment is similar to the first embodiment described above. In this embodiment, the operation of the louver 80 and the opening / closing door 91 in the duct is not performed by the servomotor 81 and the operation force of the operation performed by the occupant is performed. It is characterized in that the louver 80 operates using FIG. 14 is a diagram for explaining the operation of the louver 80 and the operation of the opening / closing door 91 in the duct.

  The air conditioner operation panel 51 is further provided with a one-seater eco mode lever 90. The single-passenger eco mode lever 90 is a lever called a driver seat (D seat) concentration lever or a single-seat concentration eco mode lever as an alias, and is a lever that is slid to change to the single passenger eco mode lever. is there. The single passenger eco mode lever 90 is configured to be slidable from a predetermined first position to a second position. The occupant can slide the single passenger eco mode lever 90 between the first position and the second position. Such a single-passenger eco mode lever 90 has the same configuration as the operation piece 81a of the servo motor 81 constituting the louver 80 of the first embodiment described above, and the single-passenger eco mode lever 90 of the present embodiment. In the first embodiment, the power source of the operation piece 81a is a servo motor.

  The single-passenger eco mode lever 90 is connected to the other ends of the four wires 86, and the single-passenger eco mode lever 90, each louver 80, and the open / close door 91 in the duct are mechanically connected by the four wires 86, respectively. Connected, the inclination of the guide plates 82 of the three louvers 80 is changed according to the position of the single passenger eco mode lever 90, and the open / close state of the open / close door 91 in the duct is switched. Therefore, it can be interlocked so that the air-conditioning range of each of the face outlets 21, 22, 31 is changed according to the slide position of the single passenger eco mode lever 90. Thus, the open / close state of the in-unit open / close door 92 is changed according to the position of the operation piece 81a.

  The state where the single passenger eco mode lever 90 is in the first position is the single passenger eco mode, and the blowing direction by each louver 80 is set so that the driver's seat space is at the center. Further, in the state where the single passenger eco mode lever 90 is in the first position, the in-duct open / close door 91 is set to be closed. Therefore, by sliding the single passenger eco mode lever 90, the three louvers 80 and the duct open / close door 91 can be operated simultaneously. Therefore, it can be interlocked so that the air-conditioning range of each of the face outlets 21, 22, 31 is changed according to the slide position of the single passenger eco mode lever 90.

  As described above, in the present embodiment, the louver 80 and the duct are displaced by the displacement of the single passenger eco mode lever 90 with a simple configuration in which the single passenger eco mode lever 90 is provided without using a drive source such as the servo motor 81. By interlocking the inner opening / closing door 91, the air conditioning range of the louver 80 for air conditioning the driver's seat can be set to a position for air conditioning around the driver's seat. Thus, since a drive source is not required, manufacturing cost can be reduced.

  Further, when the single passenger eco-mode lever 90 is arranged at the first position, it may be controlled to automatically enter the inside air mode. As a result, air is sucked from the inside air suction port 6 as in the first embodiment, so that air-conditioning air circulation can be created only in the driver's seat space.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. This embodiment has a one-seater eco mode lever 90 as in the third embodiment described above, and replaces the opening / closing door 91 in the duct of the third embodiment as in the second embodiment. A feature is that an opening / closing door 92 in the unit is provided in an opening of the air conditioning unit 1 communicating with the face outlet 32. FIG. 15 is a diagram for explaining the operation of the louver 80 provided at the face outlets 21, 22, and 31 and the operation of the in-unit opening / closing door 92.

  The single passenger eco mode lever 90 is connected to the other ends of the four wires 86, and the single passenger eco mode lever 90, each louver 80, and the unit opening / closing door 92 are mechanically respectively connected by the four wires 86. Connected, the inclination of the guide plates 82 of the three louvers 80 is changed according to the position of the single passenger eco mode lever 90, and the open / close state of the in-unit open / close door 92 is switched. Therefore, it can be interlocked so that the air-conditioning range of each of the face outlets 21, 22, 31 is changed according to the slide position of the single passenger eco mode lever 90.

  Therefore, the open / close state of the in-unit open / close door 92 is changed according to the position of the operation piece 81a. The state where the single passenger eco mode lever 90 is in the first position is the single passenger eco mode, and the blowing direction by each louver 80 is set so that the driver's seat space is at the center. In addition, when the single passenger eco mode lever 90 is in the first position, the in-unit door 92 is set to be closed. Accordingly, by sliding the single passenger eco mode lever 90, the three louvers 80 and the in-unit open / close door 92 can be operated simultaneously.

  As described above, in the present embodiment, similarly to the third embodiment described above, the single-passenger eco mode lever 90 is provided without using a drive source such as the servo motor 81, and the single-passenger eco mode lever 90 is provided. The louver 80 and the in-unit opening / closing door 92 are interlocked with the displacement of the mode lever 90 so that the air conditioning range of the louver 80 for air conditioning the driver's seat can be set to a position for air conditioning around the driver's seat. Thus, since a drive source is not required, manufacturing cost can be reduced.
