BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of an air conditioning control device, an air conditioning control method, an air conditioning control program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

[0012] (Embodiment)

FIG. 1 is a block diagram showing a functional configuration of an air-conditioning control apparatus that works according to the embodiment. The air conditioning control device 100 includes an acquisition unit 101, a determination unit 102, and a control unit 103, and controls the air conditioning of the vehicle. In addition, the air conditioning control device 100 is connected to the negative ion generator 110 and the navigation device 120.

[0013] Acquisition unit 101 acquires information related to the traveling state of the vehicle. More specifically, the acquisition unit 101 acquires information related to the running state of the vehicle from the navigation device 120 provided in the vehicle for which the air conditioning control device 100 controls air conditioning. The information related to the running state of the vehicle includes, for example, the current position of the own vehicle, the continuous running time, and output information from various sensors.

[0014] The determination unit 102 determines whether or not the information on the traveling state acquired by the acquisition unit 101 includes information indicating a state in which negative ions need to be generated. The state where negative ions need to be generated is a traveling state in which the vehicle passenger feels stress, such as traveling for a long time or traveling on a rough road. As will be described later, when the acquisition unit 101 can acquire road traffic information and weather information, it is determined whether or not the information includes information indicating a state in which negative ions need to be generated. .

Control unit 103 controls negative ion generator 110 based on the determination result of determination unit 102. Specifically, when the determination unit 102 determines that the information on the traveling state includes information indicating a state where it is necessary to generate negative ions, the negative ion generator 110 generates negative ions.

[0016] For example, when the acquisition unit 101 acquires vehicle travel time information as information relating to the vehicle travel state, the determination unit 102 determines whether the vehicle travel time information is equal to or greater than a predetermined time. . Then, the control unit 103 causes the negative ion generator 110 to generate negative ions when the travel time information of the vehicle is equal to or longer than a predetermined time. [0017] In addition, the acquisition unit 101 may acquire road traffic information from the navigation device 120. In this case, the determination unit 102 determines whether the road traffic information includes, for example, information that the vicinity of the current location of the vehicle is congested, and the control unit 103 is congested around the current location of the vehicle. Is included, the negative ion generator 110 generates negative ions.

[0018] The acquisition unit 101 may acquire weather information from the navigation device 120. In this case, the determination unit 102 determines whether the weather information includes information that the vicinity of the current position of the vehicle is in bad weather, and the control unit 103 receives information that the vicinity of the current position of the vehicle is in bad weather. If included, the negative ion generator 110 generates negative ions.

FIG. 2 is a flowchart showing a procedure of air conditioning management processing performed by the air conditioning control device. First, the acquisition unit 101 acquires information related to the traveling state of the vehicle from the navigation device 120 (step S201). Next, it is determined whether road traffic information or weather information can be obtained (step S202). If it can be obtained (step S202: Yes), obtainable information is obtained (step S203). If both road traffic information and weather information can be acquired at this time, both may be acquired. On the other hand, if neither can be acquired (step S 2 02: No), the process proceeds to step S204.

[0020] Then, it is determined from the information acquired in steps S201 and S203 whether or not negative ions need to be generated (step S204). Specifically, it is determined whether the information acquired in steps S201 and S203 includes information indicating a state in which negative ions need to be generated. When it is necessary to generate negative ions (step S204: Yes), the control unit 103 generates negative ions in the negative ion generator 110 (step S205), and ends the processing according to this flowchart. On the other hand, if it is not necessary to generate negative ions (step S204: No), the processing according to this flowchart in which negative ions are not generated in the negative ion generator 110 is terminated.

[0021] As described above, according to the air conditioning control device 100 according to the embodiment, the navigation device 120 and the negative ion generator 110 are linked to each other so that the navigation device 120 Based on the information acquired, it is possible to determine whether negative ions need to be generated. As a result, negative ions can be generated when necessary, without being operated by the passenger.

[0040] The recording medium 405 can read various control programs and various information into a computer. Record in state. The recording medium 405 accepts writing of information by the recording medium decoding unit 406 and records the written information in a nonvolatile manner.

A portable media can also be used.

[0041] The map information stored in the recording medium 405 includes background data representing features (features) such as buildings, rivers, and the ground surface, and road shape data representing road shapes. Rendered in 2D or 3D on the display screen of part 403. When the navigation apparatus 310 is guiding a route, the map information recorded on the recording medium 405 and the vehicle position acquired by the position acquisition unit 404 are displayed in an overlapping manner.

[0042] The road shape data further includes traffic condition data.

In the traffic condition data, past traffic information is stored by statistically processing the past traffic information based on the season 'day' large holidays. The navigation device 310 obtains information on the currently occurring traffic jam based on the road traffic information received by the communication unit 408, but it is possible to predict the traffic jam situation at the specified time based on the past traffic jam information. Become.

In this embodiment, the map information is recorded on the recording medium 405. However, the present invention is not limited to this. The map information may be provided outside the navigation device 310, not the one recorded with the hardware of the navigation device 310 alone. In this case, the navigation device 310 acquires map information via the network through the communication unit 408, for example. The acquired map information is stored in RAM. The recording medium decoding unit 406 controls reading / writing of information with respect to the recording medium 405. For example, when HD is used as a recording medium, the recording medium decoding unit 406 is an HDD (Hard Disk Drive). Similarly, when a DVD or CD (including CD_R, CD-RW) is used as the recording medium, the recording medium decoding unit 406 is a DVD drive or a CD drive. When a CD-ROM (CD-R, CD-RW), MO, memory card, etc. is used as the writable and removable recording medium 405, information can be written to various recording media and various recording media can be used. A dedicated drive device capable of reading stored information is used as the recording medium decoding unit 406 as appropriate.

[0045] The guidance sound output unit 407 reproduces the guidance sound by controlling the output to a connected speaker (not shown). There may be one speaker or a plurality of speakers. Specifically, the guidance sound output unit 407 can be realized by an audio I / F connected to an audio output speaker. More specifically, the audio I / F includes, for example, a D / A converter that performs D / A conversion of audio digital information, an amplifier that amplifies the audio analog signal output from the D / A converter, and audio analog It can be configured with an A / D converter that performs A / D conversion of information.

[0046] Communication unit 408 includes, for example, an FM tuner, a VICS / beacon receiver, a wireless communication device, and other communication devices, and performs communication with other communication devices. Examples of information acquired by the communication unit 408 include real-time traffic jam information and traffic regulation information (hereinafter referred to as road traffic information). Receiving road traffic information by the communication department 408 1§ The road traffic information may be delivered from the VICS (Vehicle Information and Communication System) center, or the road traffic will be regularly sent to the VICS Center. This may be done by requesting information. It is also possible to obtain road traffic information in the desired area from the VICS information collected nationwide on the server via the network. In addition, the communication unit 408 may be connected to the server, and the weather information on the route searched by the route search unit 409 described later or around the destination point may be acquired via the network.

[0047] Although it is a well-known technique, a detailed description is omitted, but “VICS” is a VICS center. It is an information communication system that transmits road traffic information such as traffic jams and traffic regulations that have been edited and processed in real time, and displays them in characters and figures on an in-vehicle device such as a powerful navigation device. As a method of transmitting road traffic information (VICS information) edited and processed at the VICS center to the navigation device 310, there is a method of using “beacon” and “FM multiplex transmission” installed on each road. . “Beacons” include “radio wave beacons” used mainly on expressways and “optical beacons” used on major general roads. When “FM multiplex broadcasting” is used, road traffic information in a wide area can be received. When using a “beacon”, it is possible to receive the necessary road traffic information at the location where the vehicle is located, such as detailed information on the most recent road based on the location of the vehicle.

[0048] The route search unit 409 uses the map information stored in the recording medium 405, the road traffic information acquired via the communication unit 408, and the like to optimally route from the departure point to the destination point. Explore. Here, the optimal route is the route that best matches the conditions specified by the user. In general, there are an infinite number of routes from a departure point to a destination point. Therefore, items to be considered in route search are set to search for routes that meet the conditions.

[0049] The route guidance unit 410 is obtained from the guidance route information searched by the route search unit 409, the vehicle position information acquired by the position acquisition unit 404, and the recording medium 405 via the recording medium decoding unit 400. Real-time route guidance information is generated based on the map information. The route guidance information generated at this time may be information considering the road traffic information received by the communication unit 408. The route guidance information generated by the route guidance unit 410 is output to the display unit 403 via the navigation control unit 401.

[0050] The guide sound generation unit 411 generates tone and voice information corresponding to the pattern. In other words, based on the route guidance information generated by the route guidance unit 410, the virtual sound source corresponding to the guidance point is set and the voice guidance information is generated, via the navigation control unit 4001. Output to guide sound output unit 407.

[0051] Air conditioning control unit 412 controls air conditioning in the vehicle based on information acquired by other components of navigation device 310. Specifically, the current position information of the vehicle acquired by the position acquisition unit 404, the output values of various sensors, and the location recorded on the recording medium 405. It is determined whether negative ions need to be generated based on the map information, road traffic information and weather information acquired by the communication unit 408. Then, if necessary, a signal for controlling on / off of the minus on generator 330 is generated and transmitted to the air conditioner controller 320.

Note that the functional configuration of the air-conditioning control apparatus 100 that is relevant to the embodiment is realized by the air-conditioning control unit 412.

[0053] (Air-conditioning management processing of the air-conditioning control unit)

5 and 6 are flowcharts showing the procedure of the air conditioning control processing performed by the air conditioning control unit. Next, an air conditioning control process performed by the air conditioning controller 412 of the navigation device 310 will be described. First, the air-conditioning control unit 412 determines whether there is information that can be acquired from each component of the navigation device 310 by itself (step S501). Information that can be acquired by the vehicle itself includes, for example, the current position information of the vehicle acquired by the position acquisition unit 404, the output values of various sensors, and the map information recorded in the recording medium 405. Information that can be acquired without using. Further, the elapsed time from the start of traveling may be acquired using the time when the power of the navigation device 310 is turned on / off. For example, it may be obtained from a clock function in the navigation device 310 or the like.

[0054] If there is information that can be acquired by the vehicle itself (step S501: Yes), information that can be acquired by the vehicle itself is acquired (step S502), and the process proceeds to step S503. On the other hand, if there is no information that can be acquired by the vehicle itself (step S501: No), information (road traffic information or weather information) on the running state of the vehicle is obtained from each component of the navigation device 310. It is determined whether it can be acquired (step S503). Specifically, the communication unit 408 determines whether road traffic information or weather information can be acquired.

[0055] If road traffic information or weather information can be obtained (step S503: Yes), obtainable information is obtained (step S504). At this time, if only one of road traffic information and meteorological information can be obtained, obtainable information may be obtained, and if both can be obtained, both may be obtained. The weather information may be acquired from a temperature or humidity sensor provided in the air conditioner controller device 320, for example. On the other hand, information that can be acquired by the vehicle alone and road traffic information 'weather information cannot be acquired In such a case (step S503: No), the process proceeds to step S514 in FIG.

[0056] When the information is acquired in step S502 or step S504, the air conditioning control unit 412 determines whether or not negative ions are generated by the negative ion generator 330 (step S505). If it is determined that negative ions are generated (step S505: Yes), the process proceeds to step S506 in FIG. On the other hand, if it is not determined that negative ions are generated (step S505: No), the process proceeds to step S514 in FIG.

[0057] Whether or not negative ions are to be generated is determined by, for example, whether the information acquired in step S502 or step S504 includes information indicating a state in which it is necessary to generate negative ions. This is done by judging whether or not. For example, if information that can be acquired by the vehicle itself is acquired in step S502, it is determined from the traffic condition data whether the road currently being driven is an unpaved road or a road with a steep slope or curve from the map information. To do. In addition, it is judged from the output values of various sensors whether high-speed driving, long-time driving, and driving on roads with steep slopes or curves are continued.

[0058] In addition, the road traffic information acquired in step S504 includes information that traffic congestion and congestion occur at the current position of the vehicle and its surroundings, time zone regulations, road surface freezing, Judge whether there is information that there is a broken vehicle, chain regulation, low speed work vehicle, etc.

[0059] Further, it is determined whether or not the weather information acquired in step S504 includes information on snow, heavy rain, lightning, earthquakes, etc. at or near the current position of the vehicle. In addition, it is judged whether the speed is restricted by fog, etc., or whether a warning warning is issued. When acquiring weather information from the air conditioner controller device 320, for example, it is determined whether or not there is a sudden change in temperature and humidity of the vehicle.

[0060] The reason for making such a determination is that these matters become stress factors that cause fatigue and reduced concentration in the passenger. The air conditioning control unit 412 determines whether or not there is a stress factor from the information acquired in step S502 or step S504, and if there is a stress factor, causes the negative ion generator 330 to start generating negative ions. As a result, the negative ion concentration in the vehicle is improved, and the sedation effect and fatigue recovery effect, which are the effects of negative ions on the human body, are prevented, thereby preventing the passenger's fatigue and reduced concentration. Ability to do S.

[0061] It should be noted that the determination at this time is performed not only on the current position of the vehicle but also on a certain range on the route, so that the negative ion concentration in the vehicle is increased in advance before the stress factor becomes apparent. Anyway.

[0062] Turning to the explanation of FIG. 6, if it is determined in step S505 that negative ions are generated (step S505: Yes), the air conditioning control unit 412 sets a timer (step S506), and the time for generating negative ions is reached. Set.

Next, the air conditioning control unit 412 determines whether the negative ion generation start request mask flag is set (step S507). When the negative ion generation start request mask flag is set, the value is “1”, and the negative ion generator 330 currently generates negative ions. When the negative ion generation start request mask flag is not set, that is, when it is cleared, the value is “0”, and the negative ion generator 330 currently stops generating negative ions. . If the air-con controller 320 is provided with the negative ion generator 330, the same process is performed for the negative ion generation switch-on mask flag.

[0064] If the generation start request mask flag is set (step S507: Yes), the negative ion generator 330 is currently generating negative ions. The process ends. On the other hand, if the generation start request mask flag is set or not (step S507: No), the generation start request mask flag is set to “1” (step S508). Then, a negative ion generation start request command is transmitted to the air conditioner controller device 320 via the communication line 11 (step S509).

The air conditioner controller device 320 that has received the generation start request command transmits a ○ N command to the negative ion generator 330 via the communication line 12. The air conditioner controller device 320 receives an “ACK” (success) or “NACK” (failure) signal from the negative ion generation device 330 and transmits the received signal to the air conditioning control unit 412.

Air conditioning control unit 412 determines whether or not the negative ion generation start request to negative ion generator 330 has succeeded based on the signal received from air conditioner controller device 320 (step S510). When the negative ion generation start request is successful (Receive If the received signal is “ACK” (step S510: Yes), the processing according to this flowchart is terminated. On the other hand, when the negative ion generation start request fails (when the received signal power S is “NACK”) (step S510: No), retry processing is performed a predetermined number of times (step S511). If it is confirmed in the retry process that negative ions are generated (step S512: Yes), the process according to this flowchart is terminated. On the other hand, if the generation start of negative ions cannot be confirmed even after retrying a predetermined number of times (Step S512: No), the generation start request mask flag is cleared and set to “0” (Step S513). The process by is terminated. As a result, the next process is performed assuming that the negative ion generator 330 has stopped generating negative ions (No in step S507).

[0067] Next, in step S505, if it is determined that negative ions are not generated (step S505: No), it is determined whether the set time of the timer has elapsed (step S514). If the set time of the timer has not elapsed (step S514: No), the process according to this flowchart is terminated without performing any particular process in order to continue generating negative signs. On the other hand, if the set time of the timer has elapsed (step S514: Yes), it is determined whether the negative ion generation start request mask flag is cleared (step S515). If the generation start request mask flag is cleared (step S515: Yes), the negative ion generator 330 stops the generation of negative ions and does not perform any particular processing. The process by is terminated.

On the other hand, when the generation start request mask flag is not cleared (step S515: No), the negative ion generator 330 is currently generating negative ions. Therefore, the generation start request mask flag is cleared to “0” (step S516). Then, a negative ion generation stop request command is transmitted to the air conditioner controller device 320 via the communication line 11 (step S517).

The air conditioner controller device 320 that has received the generation stop request command transmits an OFF command to the negative ion generator 330 via the communication line 12. The air conditioner controller 320 receives an “ACK” (success) or “NACK” (failure) signal from the negative ion generator 330 and transmits the received signal to the air conditioning controller 412. Air conditioning control unit 412 determines whether or not the negative ion generation stop request to negative ion generation device 330 has succeeded based on the signal received from air conditioner controller device 320 (step S518). If the negative ion generation stop request is successful (when the received signal is “ACK”) (step S518: Yes), the processing according to this flowchart ends. On the other hand, when the negative ion generation stop request fails (when the received signal power S is “NACK”) (step S518: No), retry processing is performed a predetermined number of times (step S519). If it is confirmed in the retry process that the generation of negative ions has been stopped (step S520: Yes), the process according to this flowchart is terminated. On the other hand, if the negative ion generation stoppage cannot be confirmed even after retrying the specified number of times (step S520: No), the generation start request mask flag is set and set to “1” (step S52 1). The process by is terminated. Thus, the next process is performed assuming that the negative ion generator 330 is generating negative ions (step S507: Yes).

[0071] As described above, according to the air conditioning control system 300 according to the present embodiment, the navigation device 310 and the negative ion generation device 330 are linked to each other, and the passenger is informed by the information acquired by the navigation device 310. The ability to judge whether negative ions are in a necessary state. As a result, minusions can be generated when necessary, without being operated by the passenger.

[0072] In addition, by generating negative ions at an appropriate time as described above, effects of negative ions such as recovery of fatigue and maintenance of concentration can be obtained more effectively. When riding a vehicle, it is possible to encourage safe driving by obtaining such effects that cause many stress factors for passengers, such as fatigue due to driving, frustration due to traffic jams and bad weather.

It should be noted that the air conditioning management method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, flexible disk, CD_ROM, M0, or DVD, and is executed by being read from the recording medium by the computer. Also this professional The gram may be a transmission medium that can be distributed via a network such as the Internet.
