  Patent Document 1 uses an exhaust gas sensor or an IR sensor for gas detection. Although the exhaust gas sensor is widely used for exhaust gas purification, the IR sensor for gas detection is not normally used for a vehicle, which causes an increase in cost. Further, if the number of types of gas to be detected is increased, it is necessary to add a sensor corresponding to the gas, and the cost further increases. Moreover, the fact that the gas detection IR sensor detects gas means that gas (odor) has already flowed into the vehicle interior, which impairs the comfort of the interior of the vehicle.

  Japanese Patent Laid-Open No. 2004-260688 discloses that after the completion of pre-air conditioning, which is an air conditioning mode performed before a vehicle occupant gets into the vehicle, and before normal air conditioning, which is an air conditioning mode performed after the vehicle occupant gets into the vehicle, is performed. Odor air conditioning is executed. However, there is no disclosure or suggestion about the deodorizing air-conditioning especially during driving after the passenger gets on.

  With the above configuration, the deodorizing air conditioning information can be output before the odor flows into the vehicle interior, and the vehicle device or the vehicle user can take necessary measures to prevent the odor from flowing into the vehicle interior (change of the air conditioning mode or window). Closing). For this reason, the user can reduce the feeling of discomfort due to odor and maintain comfort in the passenger compartment. Moreover, the configuration of the present invention can be realized even in a vehicle not equipped with a navigation device by using a current position acquisition function of a portable terminal that is widely used.

  An operation switch group 31, an air conditioning sensor group 32, and an air conditioner unit 33 are connected to the air conditioner ECU 30. The air conditioner ECU 30 is configured as a computer including a CPU that executes various arithmetic processes, a memory that stores an air conditioning control program and various types of information, and peripheral circuits.

  The operation switch group 31 is provided, for example, on an air conditioner panel provided in the center front of the instrument panel that can be operated by a driver and a passenger on the front passenger seat, and is provided with an ON / OFF switch, an air volume changeover switch, a temperature setting switch, and an outlet switch It includes switches such as a switch (MODE switch), an inside / outside air switching switch, a defroster switch, and an A / C switch. Each of these switches is configured as a well-known pressing operation unit or dial operation unit.

  The air conditioning sensor group 32 is, for example, an internal air temperature sensor that detects the temperature inside the vehicle, an external air temperature sensor that detects the outside temperature of the vehicle, a post-evaporator sensor that detects the temperature of air immediately after passing through the evaporator, and a solar radiation amount. And a known sensor such as a humidity sensor for detecting humidity in the vehicle interior.

  The air conditioner unit 33 is a known HVAC (Heating Ventilating and Air-Conditioning) unit, and includes a known refrigeration cycle (not shown) for cooling output of the air conditioner unit 33.

  The refrigeration cycle is a compressor (compressor), condenser (condenser), receiver (receiver) driven by an engine (in the case of an engine vehicle) or a motor (in the case of a hybrid vehicle or electric vehicle) provided outside the duct. ), An expansion valve (expansion valve), and an evaporator (both not shown) provided in the duct.

  The refrigerant gas compressed and liquefied by the compressor flows into the evaporator and is vaporized, thereby depriving the surrounding heat. Thus, the evaporator cools the air flow and generates cold air.

  A heater core is provided in the duct. When the heater core is a vehicle equipped with an engine, the heat of the cooling water raised by cooling the engine (in the case of an engine vehicle) or the electric heater (in the case of a hybrid vehicle or electric vehicle) is used. The air in the duct is heated to generate warm air.

  The duct of the air conditioner unit 33 includes an inside / outside air switching damper 331. The inside / outside air switching damper 331 receives air from an outside air inlet for taking in air outside the vehicle and an inside air inlet for circulating the air inside the vehicle, provided in the duct, based on a control command from the air conditioner ECU 30. Adjust the import ratio.

  An air mix damper 332 is provided in the duct of the air conditioner unit 33. The air mix damper 332 adjusts the mixing ratio between the cool air cooled by the evaporator and the warm air heated by the heater core, based on the control command of the air conditioner ECU 30.

  With the above-described configuration, the air conditioner ECU 30 controls the air conditioner unit 33 based on the operation state of the operation switch group 31 and the detection result of the air conditioning sensor group 32 by executing the air conditioning control program. Well-known air conditioning control such as temperature control, air volume control, inside / outside air switching control, and air outlet switching control is performed.

  The center 40 includes a server 41. The server 41 is a control unit 42 (correction unit of the present invention, pollution index calculation unit) and a storage unit connected to the control unit 42, for example, a hard disk device, and stores an odor map and odor information (details will be described later). 43, for example, a communication unit 44 that communicates with the mobile terminal 10 via a public communication line, and an operation unit 45 that an operator performs an input operation.

  The configuration including the center 40 described above is “including a center capable of wireless communication with a mobile terminal, the center including a storage unit that stores the location of the odor area and the contamination index in association with each other, and the mobile terminal has an odor including the current location. The information request is transmitted to the center, and when the center receives the odor information request, the center transmits the odor information corresponding to the current position to the portable terminal ”. With this configuration, the load and cost (particularly memory capacity) of the mobile terminal can be reduced by centrally managing the odor information at the center.

  An outside air state information transmission process included in the application program stored in the memory 12 of the mobile terminal 10 and executed by the CPU 11 in FIG. 2 will be described. First, it is determined whether a predetermined transmission timing has arrived. When the transmission timing has arrived (S11: Yes), the current position of the mobile terminal 10 detected by the position detection unit 16 is acquired (S12).

  Next, the outside air state detected by the outside air state detection unit 22 of the vehicle 20, that is, the detection value of the exhaust gas sensor is acquired via the short-range wireless communication unit 17 (S13). Next, the outside air temperature is acquired (S14). For example, an outside air temperature transmission request is transmitted to the air conditioner ECU 30 and a detection value of an outside air temperature sensor included in the air conditioning sensor group 32 is received.

  Next, the outside air state information in which the current position is associated with the outside air state and the outside air temperature is transmitted to the center 40 via the communication unit 13 (S15). The sensor value before correction and the detected value of the outside air temperature sensor may be included in the outside air state information.

  The above-described configuration is “the portable terminal includes an outside air state acquisition unit that acquires an outside air state that is an outside air state of the vehicle, and transmits outside air state information that associates the current position and the outside air state to the center”. . With this configuration, the latest outside air state can always be provided to the center.

  The configuration in which the outside air condition information is transmitted including the outside air temperature is “the portable terminal has an outside air temperature information obtaining unit that obtains outside air temperature information reflecting the outside air temperature of the vehicle, and the outside air temperature information associated with the current position is displayed. Included in the outside air state information and transmitted to the center ". With this configuration, the outside air state (detected value of the sensor) can be corrected using the outside air temperature.

  Deodorant air conditioning information output processing included in the application program stored in the memory 12 of the mobile terminal 10 in FIG. 3 and executed by the CPU 11 will be described. First, it is determined whether or not a predetermined execution timing of this process has arrived. When the execution timing has arrived (S31: Yes), the current position of the mobile terminal 10 detected by the position detection unit 16 is acquired (S32). Next, the odor information including the odor area where the predetermined odor stays in the predetermined range including the current position and the degree of odor (contamination index) is present via the communication unit 13. An odor information request for requesting transmission is transmitted to the center 40 (S33).

  Next, when the odor information from the center 40 is received (S34: Yes), the current position of the mobile terminal 10 detected by the position detection unit 16 is acquired again (S35). The current position acquired in step S32 may be used. Next, it is determined whether the portable terminal 10 (that is, the vehicle 20) is approaching the odor area (S36). The determination method uses at least one of the following.

When the traveling direction of the vehicle 20 (which can be estimated from the history of changes in the current position of the mobile terminal 10) is facing the odor area, it is determined that the vehicle 20 is approaching the odor area.
-When the distance between the portable terminal 10 and the outer edge of an odor area is less than a predetermined distance threshold, it determines with approaching an odor area.
-Based on the traveling direction of the vehicle 20, the speed of the vehicle 20, and the distance between the mobile terminal 10 and the outer edge of the odor area, the vehicle 20 is expected to reach the outer edge of the odor area within a predetermined time. When it is determined that it is approaching the odor area.

  When it determines with not approaching an odor area (S37: No), it returns to step S35. On the other hand, when it is determined that the vehicle is approaching the odor area (S37: Yes), it is possible to recommend deodorization air conditioning that is an air conditioning mode that suppresses the odor outside the vehicle 20 from flowing into the passenger compartment. Is determined (S38). At least one of the following is used as a method for determining whether or not recommendation is possible.

-When the state (especially the density | concentration of a carbon dioxide) of the gas (vehicle interior air) acquired from the gas detection part 23 is less than predetermined value, it determines with recommendation. For example, when the concentration of carbon dioxide exceeds a predetermined value, ventilation is prioritized over the smell outside the vehicle 20 flowing into the passenger compartment.
The above-described configuration is as follows: “The portable terminal includes an air condition acquisition unit that acquires the condition of the vehicle interior air, which is the air in the vehicle interior, and the information output unit outputs deodorant air conditioning information based on the condition of the vehicle interior air. To do. With this configuration, for example, when the air in the vehicle interior is dirty and ventilation (introduction of outside air) is necessary, introduction of outside air can be given priority over preventing odors from flowing into the vehicle interior. Therefore, although the user feels an odor, a decrease in comfort due to dirt in the passenger compartment air can be reduced.

  The configuration of estimating the interior air condition of the vehicle interior and determining that deodorizing air conditioning can be recommended is as follows: “The portable terminal is a vehicle state acquisition unit that acquires the vehicle state, and the interior of the vehicle based on the vehicle state. An air state estimating unit that estimates the state of the vehicle interior air that is the air of the vehicle, and the information output unit outputs deodorant air conditioning information based on the state of the vehicle interior air.

The current operation status of the air conditioner unit 33 is acquired from the air conditioner ECU 30. When the air conditioner unit 33 is operating in the auto mode, it is determined that the recommendation is possible. This configuration is “the vehicle state acquisition unit acquires the operating state of the air conditioner that performs air conditioning in the vehicle interior, and the air state estimation unit estimates the state of the vehicle interior air based on the operating state of the air conditioner.” Is. It is considered that the operation of operating the air conditioner unit 33 in the manual mode or the operation of stopping the air conditioner unit 33 is performed after the user recognizes the state of the surrounding odor. With this configuration, the user's intention can be prioritized.

The state of gas in the room of the vehicle 20 is estimated from the user's boarding state (passenger number, weight) acquired from the occupant detection unit 24, and it is determined that recommendation is possible when the state falls below a predetermined value.
The above-mentioned configuration is “the vehicle state acquisition unit acquires the seating state of the user in the vehicle, and the air state estimation unit estimates the state of the vehicle interior air based on the seating state”. For example, the degree of air pollution in the passenger compartment due to carbon dioxide contained in the user's exhalation varies depending on the user's seated state (that is, the number of passengers, weight, age). This configuration eliminates the need for parts and devices for detecting the state of vehicle interior air, such as a gas sensor, and can reduce costs.

-When the user's boarding time falls below a predetermined value, it is determined that the recommendation is possible. Based on the state of the vehicle 20 acquired from the vehicle state detection unit 25, for example, the boarding time is obtained by measuring the elapsed time after the prime mover is in the starting state.
The above-mentioned configuration is “the vehicle state acquisition unit acquires the user's boarding time in the vehicle, and the air state estimation unit estimates the state of the cabin air based on the boarding time”. The degree of dirt in the passenger compartment air varies depending on the boarding time. This configuration eliminates the need for parts and devices for detecting the state of vehicle interior air, such as a gas sensor, and can reduce costs.

-Based on the state of the vehicle 20 acquired from the vehicle state detection part 25, when all the windows are closed, it determines with recommendation being possible. This configuration is “the vehicle state acquisition unit acquires the open / closed state of the vehicle window, and the air state estimation unit estimates the state of the vehicle interior air based on the open / closed state of the vehicle window”. It is considered that the opening operation of the window is performed after the user recognizes the state of the surrounding odor. With this configuration, the user's intention can be prioritized.

When the deodorizing air conditioning cannot be recommended (S39: No), this process is terminated. On the other hand, when the deodorization air conditioning can be recommended (S39: Yes), the deodorization air conditioning information is output (S40). The output method uses at least one of the following.
-Display the deodorizing air conditioning information on the display unit 19 and prompt the user to perform the deodorizing air conditioning.
Deodorant air conditioning information is transmitted to the vehicle 20 via the short-range wireless communication unit 17. For example, when the air conditioner ECU 30 acquires the deodorizing air conditioning information, the inside / outside air switching damper 331 is switched to the inside air side to perform air conditioning in the inside air circulation mode. Moreover, you may adjust the opening ratio of the air mix damper 332, and may adjust the mixing ratio of cold air and warm air so that the air-conditioning wind of temperature lower than the present setting temperature may be blown out. A lower temperature may reduce the degree of odor.

  The deodorant air conditioning information may be content corresponding to a pollution index (details will be described later).

  The odor information control process executed by the control unit 42 of the server 41 of the center 40 in FIG. 4 will be described. First, it is determined whether or not an odor information request is received from the mobile terminal 10 via the communication unit 44. When the odor information request is not received (S51: No), the process proceeds to step S53. On the other hand, when an odor information request is received (S51: Yes), odor information (for example, odor map data described later) included in a predetermined range (for example, radius 5 km) from the current position of the mobile terminal 10 included in the odor information request. Is transmitted (S52). Thereafter, the process proceeds to step S53.

  When the mobile terminal 10 stores map data in the memory 12, the odor information may not be transmitted, but only a pollution index for each point or facility described later, and the position of the odor area may be transmitted. .

  In step S53, it is determined whether or not the outside air state information has been received from the mobile terminal 10. When the outside air state information is received (S53: Yes), the detection result (sensor value) of the outside air state is then corrected based on the outside air temperature included in the outside air state information (S54).

  The above-described configuration is “the center corrects the outside air state included in the outside air state information based on the outside air temperature information included in the outside air state information”. With this configuration, the correction value can be centrally managed at the center, and the accuracy of the outside air state can be improved. In addition, since it is not necessary to perform correction for each mobile terminal, the load on the mobile terminal can be reduced.

  Next, the normal value of the sensor is calculated using the correction value of the sensor (S55). For example, for each point (that is, the current position of the mobile terminal 10) or for each sensor type (included in the outside air state information), a frequency distribution is obtained from sensor values received from other mobile terminals, and the frequency is the maximum. The sensor value becomes a normal value.

  For example, when the sensor value is represented by a voltage value of 0.5 to 4.5 (V), the frequency distribution is obtained in increments of 0.1 (V). Then, the voltage value that maximizes the frequency is set as a normal value.

  The above-described configuration is as follows: “For each current position, the center stores the largest value of the outside air state values included in the outside air state information received from the mobile terminal in the storage unit as the normal value of the outside air state at the current position. To do. With this configuration, the normal value of the outside air state for each point can be obtained with a simple configuration and low cost.

  Next, for each point included in the outside air state information, the ratio between the sensor correction value calculated in step S54 and the normal value obtained in step S55 is calculated as a contamination index (S56). The larger the pollution index, the greater the odor level.

  The above-described configuration is “the center includes a pollution index calculation unit that calculates a ratio between the value of the outside air state and the normal value as a pollution index”. With this configuration, the contamination index can be calculated using a sensor that can detect only the relative change from the initial value when the power is turned on.

  Next, the normal value and contamination index of the sensor are stored in the storage unit 43 in association with the point (S57). For example, the odor map is created by plotting the pollution index for each point on the electronic map data stored in the storage unit 43. The memory | storage part 43 memorize | stores the pollution index for every point or a facility, and the position of an odor area other than an odor map.

  The pollution index may be calculated by the mobile terminal 10. For example, in the process of FIG. 2, after step S13, the normal value of the sensor is acquired from the center 40, and the contamination index is calculated. The calculated pollution index is transmitted to the center 40 together with the current position, sensor value, and outside air temperature.

  Apart from calculating the pollution index based on the outside air state information from the vehicle 20, a corresponding pollution index may be set and stored in the storage unit 43 for facilities that generate odors regularly and regularly. . Setting is performed by an operation input of the operation unit 45.

  FIG. 5 shows an example of the odor map. The current position P of the vehicle 20 (that is, the mobile terminal 10) is indicated by “▲”. The pollution index is indicated by symbols (◯, ■, ●) according to the size. The size relationship of the pollution index of these symbols is ○ <■ <●. “◯” indicates that no odor is detected, or a level at which the user does not feel uncomfortable although it is detected.

In FIG. 5, five odor areas (hereinafter abbreviated as “areas”) (A to E) are set. The area setting method uses at least one of the following.
-X factory, Y factory, and Z poultry farm are facilities that generate odors regularly and regularly (odor generation sources), so the pollution index and area corresponding to the facilities are set in advance and stored in the storage unit 43. Keep it.

  For example, since the vehicle 101 traveling in the overlapping area of the area A formed around the X factory and the area B formed around the Y factory detects the odor from both the X and Y factories, the pollution index is Indicated by ●. In addition, the pollution index of the vehicle 102 traveling near the outer edge of the area C formed around the Z chicken farm is ■ (because it is far from the odor source), and the vehicle 103 traveling near the Z chicken farm is contaminated. The index is indicated by ●. Of course, the pollution index may be calculated and set based on the outside air state information.

・ A pollution index is calculated based on outside air condition information received from a vehicle that is actually running, and an area is set.
For example, traffic congestion has occurred around the shopping center (SC), the R station, and the S station, and the exhaust gas concentration (detected by the outside air state detection unit 22) has increased. Therefore, the pollution index of vehicles (104, 105, 107 to 109) traveling in the vicinity of the SC and R stations is indicated by ●. Further, the pollution index of the vehicle 106 traveling at a point slightly away from the SC is indicated by ■. Therefore, the area D is formed to include these vehicles (104 to 109).

  Similarly, the traffic in front of the city hall is also congested by the vehicles 110 to 113, so that the exhaust gas concentration increases and the pollution index of these vehicles is indicated by ●. Therefore, the area E is formed so as to include these vehicles (110 to 113).

  Since the park is thought to smell like trees and flowers, it is not judged as a bad odor. Therefore, the pollution index of the vehicles 114 to 116 traveling on the road around the park is indicated by ◯. However, depending on the season (for example, when the amount of pollen is large), the park may be a source of odor generation.

  The odor generation area may be set based on weather conditions such as yellow sand or ash fall, and the floating state of pollen or fine particulate matter. Moreover, you may consider a wind direction. Furthermore, about a factory and SC, you may set an odor generation area according to an operation condition (whether it is an operation time zone or a business hours zone).

  The traffic congestion status (traffic information), weather information, and air information are acquired by the center 40 and reflected on the odor map in the storage unit 43, for example.

  A configuration in which the pollution index of a facility or a spot is set in accordance with the season or operating status is “the center sets a pollution index of a predetermined spot based on date and time information”. With this configuration, a more accurate odor map can be created.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
