Description

  The present invention relates to a vehicle air conditioner that is used in a vehicle that includes an openable and closable partition that defines a compartment and that can travel with the partition open.

  Conventionally, an automatic air conditioner for a vehicle, that is, an automatic air conditioner, determines a necessary blowout temperature Tao based on a set temperature Tset that can be arbitrarily set by an occupant, and an indoor temperature Tr, an outside air temperature Tair, and an amount of solar radiation Ts determined by the environment outside the vehicle interior Thus, the passenger compartment is maintained at a set temperature so that comfortable air conditioning can be performed. However, when there is no partition wall that blocks outside air, solar radiation, or traveling wind, such as when the roof is opened with an open car, the conventional air conditioning control alone may feel uncomfortable in the air conditioning of the control result.

  In the conventional auto air conditioner, the room temperature sensor for detecting the room temperature Tr selects a place considered to be optimal according to the vehicle type, and is uniformly arranged at the same position for each vehicle type. Therefore, normally, it changes in substantially the same manner in parallel with the surrounding environment of the passenger and the surrounding environment of the internal temperature sensor. However, when the roof is opened with an open car, the detected value Tr of the inside air temperature sensor may greatly deviate from the temperature experienced by the occupant depending on the outside air, solar radiation, or traveling wind. Therefore, the blowing temperature Tao calculated based on the detected value Tr of the inside air temperature sensor may be different from the blowing temperature desired by the occupant. This happens not only when the roof of an open car is opened, but also when the power window is opened. Furthermore, even when an openable / closable wall or window that separates the passenger compartment is opened, the passenger may feel uncomfortable with the air conditioning by the automatic air conditioner.

Conventionally, it is well known that the air temperature can be changed when the air conditioning environment does not match the occupant's thermal sensation (see Patent Document 1). However, it does not disclose a problem based on the difference between the temperature detected by the internal air temperature sensor and the sensible temperature of the occupant, and therefore does not attempt to solve this problem.
JP-A-7-172147

  In view of the above problems, an object of the present invention is to provide a vehicle air conditioner that adjusts the temperature at which air is discharged from an air conditioning duct in an automatic air conditioner so that the air conditioning experienced by the passenger does not feel uncomfortable.

  In order to achieve the above-mentioned object, the invention according to claim 1 is used for a vehicle that includes an openable / closable partition wall (5, 6, 7) for defining a compartment and is capable of traveling with the partition wall opened. A vehicle air conditioner that includes a temperature setting switch (41) for setting a target temperature, an air conditioning selection switch (42) that can be used by opening the partition wall, and a vehicle interior temperature sensor (31). Based on the various sensors (31, 32, 33) for acquiring the temperature, the temperature set by the temperature setting switch (41) and the input from the various sensors (31, 32, 33), the vehicle interior air conditioning is automatically performed. A control unit (3) for controlling, and in conjunction with the air-conditioning selection switch (42) being turned on, at least the input of the vehicle interior temperature sensor (31) to the control unit (3) is cut off. And

  As a result, when the temperature distribution in the passenger compartment changes greatly due to the opening of the partition wall, and the air conditioning by the auto air conditioner gives the passenger a sense of incongruity, the air temperature selection switch is operated by the passenger to set the outlet temperature to the temperature set by the passenger. By approaching, passengers can feel less uncomfortable.

  According to a second aspect of the present invention, the various sensors further include a solar radiation sensor (32) and an outside air temperature sensor (33). The input to either of the control devices of the temperature sensor (33) is cut off, or the inputs of both the solar radiation sensor (32) and the outside air temperature sensor (33) to the control device are cut off. Thereby, the blowing temperature by the air conditioning executed by the air conditioning selection switch can be made closer to the temperature set by the passenger.

  A third aspect of the present invention is an air conditioner for a vehicle that includes an openable / closable partition wall (5, 6, 7) that defines a compartment, and is used in a vehicle that can travel with the partition wall open. The temperature setting switch (41) for setting the target temperature, the various sensors (31, 32, 33) for acquiring the environmental state including the vehicle interior temperature sensor (31), and the temperature setting switch (41). A controller (3) for automatically controlling the air conditioning in the vehicle interior based on the temperature and the input from the various sensors (31, 32, 33), and at least the vehicle interior air temperature in conjunction with the opening of the partition wall. An input to the control unit (3) of the sensor (31) is cut off.

  As a result, when the temperature distribution in the passenger compartment changes greatly due to the opening of the bulkhead and the air conditioning by the auto air conditioner gives the passenger a sense of incongruity, the blowout temperature approaches the temperature set by the passenger in conjunction with the opening of the bulkhead. This can reduce the discomfort of the passengers.

  According to a fourth aspect of the present invention, the various sensors further include a solar radiation sensor (32) and an outside air temperature sensor (33), and the solar radiation sensor (32) and the outside air temperature sensor are further interlocked with the opening of the partition wall. The input to any one of the control devices in (33) is cut off, or the inputs to both the solar radiation sensor (32) and the outside air temperature sensor (33) to the control device are cut off. Thereby, the blowing temperature by the air conditioning executed by the air conditioning selection switch can be made closer to the temperature set by the passenger.

  According to a fifth aspect of the present invention, the partition wall is a partition wall (5, 6) that blocks the passenger compartment from the outside air, and even if the passenger feels uncomfortable with the air conditioning due to the inflow of the outside air into the passenger compartment, the discomfort is felt. Can be reduced.

  According to a sixth aspect of the present invention, the partition wall is a partition wall (7) for partitioning the passenger compartment, and the partition wall for partitioning the passenger compartment is opened, so that air flows from other places in the vehicle to the passengers. Even when a sense of incongruity with air conditioning occurs, it can be reduced.

  In addition, the code | symbol in the parenthesis attached | subjected to the component of invention is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram schematically showing a first embodiment of a vehicle air conditioner according to the present invention, and FIG. 2 is a diagram schematically showing an open car as an example to which the present invention is applied. As an example of the partition wall to which the present invention is applied, a movable roof of an open car is shown, but the present invention is not limited to this. A member that divides the passenger compartment and the outside air and that can run while the member is opened corresponds to the partition wall of the present invention. For example, a window such as a power window may be used. Furthermore, a movable wall or a movable window that divides the passenger compartment can be regarded as the partition wall of the present invention. In any case, the partition wall according to the present invention is an openable / closable member that separates the passenger compartment, and can travel while the member is opened, and the member that makes the passenger feel uncomfortable with the air conditioning by opening the member. is there.

  As shown in FIG. 1, at the upstream end of the air conditioning duct 2 that is an air flow path of the vehicle air conditioner 1, an inside air inlet for sucking in the passenger compartment air and an outside air inlet for sucking outside air are selected. A suction port switching door 11 that opens and closes is provided. The inlet switching door 11 is opened and closed by an inside / outside air switching servo motor 12.

  A blower blower 13 is disposed downstream of the suction port switching door 11, and air sucked from the outside air suction port or the inside air suction hole is blown by the blower blower 13 in the direction of the blowout port.

  An evaporator 15 that cools the air is disposed downstream of the blower blower 13, and all of the air blown by the blower blower 13 passes through the evaporator 15. A heater core 16 that heats air is disposed downstream of the evaporator 15, and the heater core 16 heats air using cooling water of an engine (not shown) that drives the vehicle as a heat source.

  An air mix door 17 is provided upstream of the heater core 16 to adjust the air volume ratio between the air passing through the heater core 16 and the air not passing through the heater core. The opening degree of the air mix door 17 is adjusted by an air mix servo motor 18. As a result, the ratio of cold air and hot air is adjusted, and the air conditioning temperature is determined.

  An air outlet switching door 20 is provided at the most downstream side of the air conditioning duct 2 to switch between the air outlet and the air outlet for blowing the conditioned air into the vehicle interior. The opening of the outlet switching door 20 is adjusted by the outlet switching servomotor 21. FIG. 1 schematically illustrates a pair of outlet switching doors 20 and an outlet switching servomotor 21 for switching outlets.

  As shown in FIG. 2, the air-conditioning duct 2 usually has a face opening 23 (two openings are shown in FIG. 2) for blowing conditioned air to the upper body of the occupant, and a foot of the occupant. A foot opening 24 for blowing air and a defroster opening 25 for blowing air toward the inner surface of the windshield are provided. Actually, each is provided with a blowout port switching door, and the blowout mode is switched by opening and closing each opening by interlocking these doors. Furthermore, the air volume from each outlet can be adjusted by adjusting the opening of these doors.

  An electronic control unit (ECU) 3 is provided to control the automatic air conditioner. The ECU 3 includes a central processing unit (CPU), a storage device (RAM) that can be read and written as needed, a read-only storage device (ROM), and the like. The ECU 3 is activated by being supplied with power from a battery (not shown) when an ignition switch (not shown) of the vehicle is turned on, and is stored in the ECU 3 when the air conditioner switch for starting the operation of the air conditioner 1 is turned on. Start running the computer program.

  The vehicle is provided with an inside air temperature sensor 31 that detects the temperature inside the vehicle interior, a solar radiation sensor 32 that detects the amount of solar radiation that enters the vehicle interior, and an outside air temperature sensor 33 that detects the temperature of the outside air. A temperature setting switch 41 capable of setting the room temperature Tset is provided.

  The ECU 3 performs an automatic air conditioner operation based on input signals from the sensors 31 to 33 and the temperature setting switch 41. That is, control signals are output to the blower motor 14, the air mix door servo motor 18, the servo motor 12 that drives the inside / outside air switching door 11, and the servo motor 21 that drives the outlet switching door 20 to adjust the temperature and air volume. To do. Note that, in an auto air conditioner, other information such as information from the post-evaporator sensor is usually considered, but the description is omitted because it is not directly related to the operation of the present embodiment.

  In the present embodiment, there is provided an air conditioning selection switch 42 that can further select or switch the air conditioning and can bring the blowing temperature close to a desired temperature. The air conditioning selection switch 42 is a switch that can be operated when the roof 5 of the open car (FIG. 2) is opened by turning on the roof opening switch 43. After the roof 5 is opened, the input of the detection signal of the internal air temperature sensor 31 to the ECU 3 is cut off by operating the air conditioning selection switch 42 that has become operable.

  FIG. 3 is a block diagram for explaining the operation of the air conditioning selection switch 42 which is the second temperature setting switch. When the roof opening switch of the open car is turned on, the roof 5 is opened and the air conditioning selection switch 42 is operable. Here, when the air-conditioning selection switch 42 is turned on, the ECU 3 blocks the input of the detection signal of the inside air temperature sensor 31 and is determined by the detection signal of the solar radiation sensor 32 and the outside air temperature sensor 33 and the temperature setting switch 41. The blowing temperature Tao is calculated based on the Tset. Next, the ECU 3 determines the opening degree of the air mix door 17 based on the calculated blowing temperature Tao, and creates a switching instruction for the air mix servo motor 18. When receiving an instruction from the ECU 3, the air mix servo motor 18 drives the servo motor according to the instruction, controls the opening degree of the air mix door 17, and adjusts the blowing temperature. The opening degree of the air mix door is sent to the ECU 3 as a position detection signal by the potentiometer 19 to verify whether the servo motor is operating normally.

  In this way, even when the detection signal of the internal air temperature sensor 33 deviates from the passenger's sensible temperature due to the opening of the roof, the air-conditioning selection switch 42 is turned on to blow out without considering the output of the internal air temperature sensor 31. Since the temperature Tao is determined, air conditioning that does not give the passenger a sense of incongruity can be performed.

  Further, by turning on the air conditioning selection switch 42, not only the detection signal of the inside air temperature sensor 31 but also one or both of the detection signals of the solar radiation sensor 32 and the outside air temperature sensor 33 are blocked from being input to the ECU 3. It may be. These selections can be made freely selectable by the occupant after the air-conditioning selection switch 42 is turned on. Further, in the present embodiment, the air conditioning selection switch 42 only gives the ECU a signal for shutting off the sensor output, and the temperature setting follows the setting of the temperature setting switch 41. However, when the air conditioning selection switch 42 is turned on, the setting of the temperature setting switch 41 can be canceled and the temperature can be set by the air conditioning selection switch 42. The set temperature may be displayed to the occupant, but the value of the temperature itself may be displayed, but the percentage display is MAX-COOL giving the lowest temperature 0% and MAX-HOT giving the highest temperature 100%. But you can.

  In the present embodiment, the air conditioning selection switch 42 can be operated by opening the roof of the open car. However, the air conditioning selection switch 42 can also be operated by opening the power window 6 shown in FIG. . In other words, the present invention can be applied to a vehicle in which the partition that blocks the passenger compartment from the outside air is opened and the vehicle can travel as it is. Further, as shown in FIG. 5, there is a partition wall 7 such as a wall or a window for partitioning the passenger compartment. When the partition wall is movable, the air conditioning selection switch 42 is operated by opening the movable partition wall. It can also be possible. In any case, when the passenger feels uncomfortable with the air conditioning due to the opening of the partition that separates the passenger compartment, the uncomfortable feeling can be reduced.

  FIG. 4 is a flowchart showing an air conditioning control operation according to the first embodiment of the present invention.

  When the air conditioning control starts, it is first determined in step S1 whether or not the open car roof 5 (FIG. 2) has been opened. The means for determining whether or not the roof 5 has been opened can be determined by turning on and off the roof opening switch 43. Alternatively, the opening of the roof may be detected by a sensor.

  If the roof 5 is not opened, the process proceeds to step S5, based on the temperature Tset set by the occupant by the temperature setting switch 41, the input signals of various sensors including the inside air temperature sensor 31, the solar radiation sensor 32, and the outside air temperature sensor 33. Then, the necessary blowout temperature Tao is calculated, and the conventional automatic air conditioner control is performed.

  If it is determined in step S1 that the roof 5 is open, the passenger is informed in step S2 that the air conditioning selection switch 42 is usable. As a method for notifying the occupant, a switch lamp for displaying the operation of the air conditioning selection switch 42 may be blinked. Further, the fact that the air conditioning selection switch can be used may be displayed on a display arranged on an instrument panel such as a car navigation display or a display panel for displaying various measurement values. Furthermore, the passenger can be notified by voice.

  Next, in step S3, it is determined whether or not the air conditioning selection switch 42 has been turned on. When the occupant turns on the air-conditioning selection switch 42 and sets a desired temperature, the detection signal of the inside air temperature sensor 31 among the sensor outputs used for conventional automatic air-conditioner control is cut off. Therefore, the ECU 3 calculates the blowing temperature Tao based on the desired temperature Tset set by the occupant and the detection signals of the solar radiation sensor 32 and the outside air temperature sensor 33 without using the detection signal of the inside air temperature sensor 31. In this way, even if the temperature detected by the inside air temperature sensor 31 and the temperature felt by the occupant deviate by opening the roof of the open car, the temperature set by the occupant is appropriately reflected in the blowing temperature Tao. It is possible to perform air conditioning that does not give the passenger a sense of incongruity.

  In some cases, not only the detection signal of the inside air temperature sensor 31 but also the input of the detection signal of the solar radiation sensor 32 or the outside air temperature sensor 33 to the ECU 3 may be blocked. Further, all the detection signals of the inside air temperature sensor 31, the solar radiation sensor 32, and the outside air temperature sensor 33 are cut off, and the occupant uses the air conditioning selection switch 42 to set the set temperature Tset itself as the blowing temperature. You may make it do.

  Even if the air conditioning selection switch 42 can be used in step S3, if the occupant does not turn on the air conditioning selection switch 42, the process proceeds to step S4, and the conventional automatic air conditioning control is continued. If the occupant does not turn on the air conditioning selection switch 42, the notification that informs the occupant that the air conditioning selection switch 42 can be used may end when a predetermined time has elapsed. However, when the roof 5 is opened, the air conditioning selection switch 42 can be used at any time.

6 to 8 show a second embodiment of the present invention. In the first embodiment, the opening of the movable roof of the open car enables the operation of the air conditioning selection switch, and the passenger operates the air conditioning selection switch to shut off the input of the internal air temperature sensor, thereby setting the occupant. The blow-off temperature is close to the measured temperature. In the present embodiment, when it is detected that the movable roof of the open car is opened without the operation of the air conditioning selection switch by the occupant, the input of the inside air temperature sensor is automatically cut off.
The second embodiment is the same as the first embodiment except that the air conditioning selection switch 42 of the first embodiment is omitted. Hereinafter, description of members without change will be omitted, and only changes will be described.

  FIG. 6 is a diagram schematically showing a vehicle air conditioner according to the second embodiment, and FIG. 7 shows a main part of the second embodiment shown in FIG. When the roof 5 of the open car is opened by turning on the roof opening switch 43, an ON signal of the roof opening switch 43 is input to the ECU 3. When the ON signal of the roof opening switch 43 is input, the ECU 3 blocks the input of the detection signal of the inside air temperature sensor 31 to the ECU 3.

  The ECU 3 blocks the input of the detection signal of the inside air temperature sensor 31 by the input of the roof opening signal, and based on the detection signal of the solar radiation sensor 32 and the outside air temperature sensor 33 and Tset determined by the temperature setting switch 41. The blowout temperature Tao is calculated. Next, the ECU 3 determines the opening degree of the air mix door 17 based on the calculated blowing temperature Tao, and creates a switching instruction for the air mix servo motor 18. When receiving the instruction from the ECU 3, the air mix servo motor 18 drives the air mix servo motor 18 in accordance with the instruction, controls the opening degree of the air mix door 17, and adjusts the blowing temperature. The opening degree of the air mix door is sent to the ECU 3 as a position detection signal by the potentiometer 19 to verify whether the servo motor is operating normally.

  As described above, in the second embodiment, in conjunction with the opening of the roof, the operation is performed so as to determine the blowing temperature Tao without considering the output of the internal air temperature sensor 31, so that the passenger's hand is not bothered. Air conditioning that does not give the passenger a sense of incongruity can be executed.

  Further, in conjunction with the opening of the roof, not only the detection signal of the inside air temperature sensor 31 but also one or both of the detection signals of the solar radiation sensor 32 and the outside air temperature sensor 33 are blocked from being input to the ECU 3. Also good. In the present embodiment, an example is shown in which the operation is performed in conjunction with the opening of the roof of the open car. However, the operation can be performed in conjunction with the opening of the power window or the opening of the partition partitioning the vehicle interior. In any case, when the passenger feels uncomfortable with the air conditioning due to the opening of the partition that separates the passenger compartment, the uncomfortable feeling can be reduced.

  FIG. 8 is a flowchart showing the air-conditioning control operation of the second embodiment of the present invention. When the air conditioning control is started, it is first determined in step S11 whether or not the open car roof 5 (FIG. 2) has been opened. The means for determining whether or not the roof 5 has been opened can be determined by turning on and off the roof opening switch 43. Alternatively, the opening of the roof may be detected by a sensor such as a magnet sensor.

  If the roof 5 is not opened, the process proceeds to step S13, on the basis of the temperature Tset set by the occupant by the temperature setting switch 41 and input signals of various sensors including the inside air temperature sensor 31, the solar radiation sensor 32, and the outside air temperature sensor 33. The necessary blow-off temperature Tao is calculated and the conventional automatic air conditioner control is performed.

  If it is determined in step S11 that the roof 5 is open, in step S12, the input of the detection signal of the inside air temperature sensor 31 to the ECU 3 is shut off from the sensor output used for the conventional automatic air conditioner control. Therefore, the ECU 3 calculates the blowing temperature Tao based on the desired temperature Tset set by the occupant and the detection signals of the solar radiation sensor 32 and the outside air temperature sensor 33 without using the detection signal of the inside air temperature sensor 31. In this way, by opening the roof of the open car, even if the temperature detected by the internal air temperature sensor and the temperature felt by the occupant deviate, the temperature set by the occupant is appropriately reflected in the blowing temperature Tao. It is possible to perform air conditioning that does not give the passenger a sense of incongruity.

  In some cases, in conjunction with the opening of the roof, not only the detection signal of the inside air temperature sensor 31 but also the input of the detection signal of either the solar radiation sensor 32 or the outside air temperature sensor 33 to the ECU 3 may be blocked. . Furthermore, all the detection signals of the inside air temperature sensor 31, the solar radiation sensor 32, and the outside air temperature sensor 33 may be cut off, and the set temperature Tset itself may be set as the blowing temperature.

  Furthermore, it may be displayed on the display arranged on the instrument panel such as a display for displaying car navigation or a display panel for displaying various measurement values that the air conditioning has been changed by opening the roof. Furthermore, the passenger can be notified by voice.

  As shown in FIG. 9, a cancel switch 45 may be interposed between the roof opening switch 43 and the ECU 3. Even when control is performed to block the input to the ECU 3 of the internal air temperature sensor 31 in conjunction with the opening of the roof, if necessary, the cancel switch 45 is operated so that the roof opening signal is not input to the ECU 3. Thus, the conventional air conditioning using the input of the inside air temperature sensor 31 can be executed.
