Here, the driving support method is a case where the driving support device 300 acquires the driving support information 360 and refers to the content of the driving support information 360, and as a result, is directed to an area where the alert information acquisition probability is equal to or greater than a threshold value. In addition, according to the type of alert information after the scent is generated in the vehicle in which the driving support device 300 is mounted once at a point in front of the area (for example, a point 10 km in front) To control the scent.

  First, the route search unit 102 performs a route search according to an input operation to the driving support device 300, and holds the searched route.

  The current location information acquisition unit 101 acquires the latitude / longitude information and the date / time information acquired from the latitude / longitude information from the GPS receiver 18. In addition, the said present location information acquisition part 101 shall acquire the latitude / longitude information and the date information which acquired the latitude / longitude information continuously.

  Then, the driving support information acquisition unit 104 transmits the latitude / longitude information acquired by the current location information acquisition unit 101 to the driving support information providing server 250 and requests to provide the driving support information 360. From 250, driving support information 360 corresponding to the area around the latitude / longitude information is acquired.

  And the awakening effect control part 105 reads the content of the said driving assistance information 360, and each attention alert information applicable to the area corresponding to route information, and the time slot | zone corresponding to driving time (time which acquired present location information). It is determined whether or not there is an area (hereinafter also referred to as an attention target area) in which the acquisition probability is equal to or higher than a threshold (for example, 50%). The awakening effect control unit 105 determines that the vehicle equipped with the driving support device 300 is based on the latitude / longitude information acquired by the current location information acquisition unit 101 when there is an attention target area as a result of the determination. When it is detected that a predetermined position in front of the area (for example, 10 km before the area to be alerted) is detected, a scent is generated from the scent generating device 80.

  The example of the location which generate | occur | produces a fragrance is demonstrated using FIG. As shown in FIG. 8, when the driving support device 300 detects that a vehicle equipped with the driving support device 300 has arrived at a point P1 that is in front of the attention target area, the awakening effect control unit 105 generates a scent. .

  Here, FIG. 9 shows an example of a fragrance pattern generated by the driving assistance device 300 after the vehicle has reached the point P1 that is in front of the alert target area.

  The awakening effect control unit 105 generates a scent for a predetermined time (for example, 1 minute) every predetermined time (for example, every 3 minutes). The awakening effect control unit 105 makes a scent generation request to the scent generating device 80, whereby the air pump 82 is continuously driven during a period in which the scent is generated. And the awakening effect control part 105 makes the blower 86 repeat a drive and a stop during the period which generates a fragrance by making a fragrance generation | occurrence | production request | requirement with respect to the fragrance generating apparatus 80. FIG.

  Thereby, the arousal effect control unit 105 can generate a scent in the vehicle by providing a so-called fluctuation to the scent generating device 80.

  Then, when the vehicle equipped with the driving support device 300 reaches the alerting target area as shown at the point P2 in FIG. 8, the awakening effect control unit 105 makes a deodorizing request to the scent generating device 80, Deodorize the scent in the car. The ventilator 90 may be operated at the same time.

  Then, when the information corresponding to the alert target area is dangerous attention information, the awakening effect control unit 105 keeps deodorizing, and when the information corresponding to the alert target area is road information, the alertness control unit In the same way as from point P1 to point P2, 105 provides fluctuation to the scent generating device 80 to generate scent in the vehicle.

  As described above, the driving support device 300 performs alerting by generating a scent in front of the alerting target area, and performs predetermined alerting again after the vehicle enters the alerting target area. Therefore, the driving assistance device 300 can perform an effective alerting to the driver as compared with the case where the scent is generated after reaching a position such as a traffic jam.

  In addition, the driving support device 300 causes the awakening effect by generating a scent in the vehicle using the scent generating device 80. According to this, the driving assistance device 300 can maintain the awakening effect for a longer time than other awakening effects (vibration, sound, etc.).

  And since the above-mentioned driving support device 300 provides not only traffic jam information but also forward obstacle information, etc., providing more information to the user compared to the case of providing only traffic jam information. Can do.

  When the information corresponding to the alert target area is the danger alert information, the driving support device 300 maintains the deodorized state in the vehicle in the alert target area. . In this case, the driving assistance device 300 can prevent the driver from being unable to concentrate on driving due to the awakening effect even though the degree of danger is high by stopping the awakening effect.

  And the driving assistance information 360 has a warning information acquisition probability for each time zone. According to this, the driving support device 300 can determine whether or not to generate the awakening effect based on the traveling time zone, and there is a high possibility of acquiring the alert information for each time zone. In different cases, it is possible to avoid unnecessarily generating an awakening effect.

[Driving support processing]
Below, the procedure of a driving assistance process is demonstrated using the flowchart shown in FIG. This process is realized by the system controller 20 of the driving support apparatus 300 executing a program prepared in advance.

  First, the route search unit 102 searches for a route by a user input operation or the like (step S1). And the present location information acquisition part 101 acquires the latitude longitude information and the latitude longitude information acquisition date via the GPS receiver 18 (step S2). The current location information acquisition unit 101 continues to acquire latitude / longitude information and latitude / longitude information acquisition date / time at predetermined intervals. Then, the driving support information acquiring unit 104 transmits the latitude / longitude information acquired by the current location information acquiring unit 101 to the driving support providing information server 250 and requests to provide the driving support information 360, thereby driving support information Driving support information 360 is acquired from the providing server 250 (step S3).

  Then, the awakening effect control unit 105 refers to the driving support information 360 acquired from the driving support information providing server 250, refers to the area corresponding to the route information, and the time zone corresponding to the travel time (the time when the current location information is acquired). It is determined whether or not there is an area to be alerted for which each of the alert information acquisition probability corresponding to the above is a threshold value or more, and if the area to be alerted does not exist (step S4; No), the driving support process is terminated, If there is an alert target area (step S4; Yes), the awakening effect control unit 105 identifies the alert target area and continues the driving support process.

  Then, the awakening effect control unit 105 refers to the latitude / longitude information acquired by the current location information acquisition unit 101, and determines whether or not it has reached 10 km before the area to be alerted (step S5). Then, when the awakening effect control unit 105 has reached 10 km before the area to be alerted (step S5; Yes), it makes a scent generation request to the scent generating device 80, and the scent generating device 80 fluctuates. Is provided to generate a scent in the vehicle (step S6).

  Then, the awakening effect control unit 105 refers to the latitude / longitude information acquired by the current location information acquisition unit 101 and determines whether or not the attention target area has been reached. In the case (step S7; Yes), a deodorizing operation request is made to the scent generating device 80 to deodorize the scent (step S8).

  Then, when the alert information corresponding to the alert target area is not only road information (step S9; No), the awakening effect control unit 105 ends the driving support process and the alert corresponding to the alert target area. When the arousal information is only road information (step S9; Yes), a scent generation request is made to the scent generating device 80, and a scent is generated in the vehicle by providing fluctuation to the scent generating device 80 (step S10). When the vehicle equipped with the driving support device 300 exits the area to be alerted, the scent generating device 80 is requested to deodorize, the scent is deodorized (step S11), and the driving support processing is terminated.

  According to the above configuration, the driving support device 300 acquires driving support information including current location information acquisition means for acquiring current location information, a plurality of types of alert information corresponding to the area, and related information of the alert information. To identify the area to be alerted based on the relevant information of the alerting information acquired by the driving support information acquiring means, the alerting effect generating means for generating the alerting effect, and the current location information And awakening effect control means for controlling the action of the awakening effect based on the type of the alerting information within the alerting target area. .

  In this way, the driving support device 300 acquires driving support information related to the area around the current location, identifies the area to be alerted based on the content of the driving support information, and alerts the vehicle on which the driving support device is mounted. Since the awakening effect can be generated before reaching the target area, the driver can be alerted early.

[Modifications, etc.]
[Modification of injection section]
In the above-described embodiment, the blower 86 functions as the scent injection means. However, the scent injection is performed on the injection unit 89 including the container 88 for temporarily storing the scent between the air tube 83C and the blower 86, and the blower 86. You may make it use a means.

  Here, an example of the injection unit 89 is shown in FIG. The injection unit 89 includes a blower 86 and a container 88 as illustrated. The container 88 temporarily accumulates scent between the air tube 83 </ b> C and the blower 86. The scent control unit 81 generates a negative pressure in the container 88 by rotating the blower 86. Then, the scent generating device 80 can suck up the scent generated by the scent generating unit 81 to the emitting unit 89. Therefore, the scent generating device 80 can efficiently derive fragrance molecules by applying a negative pressure. The container 88 is provided with a hole through which air from outside the container passes, and the scent generating device 80 can adjust the negative pressure.

  Further, it is desirable that the arrangement position of the blower 86 in the injection unit 89 is within a range of 30 cm or less from the center position on the partition plate between the passenger compartment and the trunk room.

[Detailed description and modification regarding arrangement position]
In the above-described embodiment, it has been described that the main body 87 is arranged in the trunk room and the blower 86 is arranged on the dashboard. Details of the arrangement example will be described below.

  An example of arrangement positions of the main body 87 and the injection unit 89 is shown in FIG. The main body 87 is disposed on the floor of the trunk room that can be shielded from light when the back door is closed, and the injection portion 89 is disposed at the center of the partition plate between the passenger compartment and the trunk room (for example, on the rear dashboard).

  In the case of the above example, since the injection part 89 is arranged in the center part on the partition plate between the passenger compartment and the trunk room, the air injected by the injection part 89 is not blocked by the backrest part of the passenger compartment seat. The scent can be provided to the occupant through the space between the left and right sheets, and the scent can be prevented from adhering to the sheet surface.

  Moreover, since the height of the arrangement | positioning position of the injection | emission part 89 becomes the height vicinity of a passenger | crew's face and the scent generator 80 will provide a passenger | crew with a scent in the shortest distance, it is the most fragrance with respect to a passenger | crew. Can be strongly detected. Therefore, the scent generating device 80 can make the occupant sense the scent even when a small amount of scent is emitted.

  Furthermore, since the scent generating device 80 has a short distance between the main body 87 and the injection unit 89, the air tube 83C connecting the scent generation unit 81 and the injection unit 89 can be shortened. Therefore, the scent generating device 80 can reduce the amount of fragrance molecules of the fragrance attached to the air tube 83C when the scent is generated.

  Another example of the arrangement is shown in FIG. In this case, the main body 87 is disposed in the gap portion between the spare tire storage portion and the floor of the trunk room, and the injection portion 89 is disposed at the ceiling position at the rear portion of the driver seat.

  Also in this example, the scent generating device 80 is disposed in a light-shielding space where the main body 87 is isolated from the passenger compartment, so that the essential oil in the main body 87 is volatilized under the influence of the temperature rise in the passenger compartment and direct sunlight. Can be prevented.

  In addition, since the scent generating device 80 is disposed at the ceiling position behind the driver's seat, the scent emitted by the injection unit 89 can be prevented from being blocked by the seat back portion.

  As for the main body 87, as shown in FIGS. 14 (a) and 14 (b), the main body 87 may be disposed in the gap portion of the spare tire storage portion.

  Even in this case, the scent generating device 80 is disposed in a light shielding space where the main body 87 is isolated from the passenger compartment, so that the essential oil in the scent generating portion 81 is removed under the influence of temperature rise in the passenger compartment or direct sunlight. Volatilization can be prevented.

[Modification of control method]
As described above, when the arousal effect control unit 105 realized by the system controller 20 determines that the area is close to an area having a high alerting information acquisition probability, it makes a scent generation request to the scent generation device 80. . That is, the awakening effect control unit 105 controls the generation of scent based on the position of the driving support device 300 (so-called position information) and the driving support information 360 (so-called road information) that is road condition information of the planned travel area. Although the case where it carries out was described, you may make it the awakening effect control part 105 perform a fragrance generation | occurrence | production request | requirement according to the various conditions described below.

(Example 1) Control based on user input information The awakening effect control unit 105 responds to acquisition of a scent generation command based on a predetermined operation (for example, operation of the input device 60) by the user, and the scent generation device 80. A scent generation request may be made to the scent control unit 81.

(Example 2) Control based on vehicle behavior information The awakening effect control unit 105 may make a scent generation request to the scent control unit 81 of the scent generation device 80 based on vehicle behavior information.

  Here, the vehicle behavior information means information generated based on various information acquired from the autonomous positioning device 10, the GPS receiver 18, or the like.

  As a specific example, a stop state for a certain time or longer (for example, 1 minute), a sudden acceleration (for example, 0.3 G) or more in a traveling direction, a sudden deceleration (for example, -0.3 G), a lateral direction Sudden steering operation, repeated stopping / running when the speed is below a predetermined speed (for example, 20 km / h) within a certain time (for example, 15 minutes), and intermittent operation for a predetermined number of times (for example, 50 times) When detected, a scent generation request is made to the scent control unit 81.

(Example 3) Control based on vehicle behavior information and position information The awakening effect control unit 105 may make a scent generation request based on vehicle behavior information and vehicle position information. As a specific example, when the current location is located in the vicinity of an intersection or a railroad crossing, the awakening effect control unit 105 makes a scent generation request when the current location is stopped for a certain period (for example, 1 minute). The vehicle position information is specified using map information, information acquired from the GPS receiver 18 or the like.

(Example 4) Control based on vehicle behavior information, position information, and traffic information The awakening effect control unit 105 smells based on vehicle behavior information, vehicle position information, and traffic information (for example, traffic jam information). A generation request may be made. As a specific example, based on the driving support information 360 and other road information (such as VICS information) and the current position information (for example, information acquired from the GPS receiver 18), the current position is a traffic jam location. When it can be determined, the awakening effect control unit 105 makes a scent generation request when the vehicle is in a stopped state for a certain time or longer (for example, 1 minute).

  Here, the procedure of the scent request control process in which the awakening effect control unit 105 makes a scent generation request based on vehicle behavior information and the like will be described based on the flowchart shown in FIG. This process is realized by the system controller 20 of the driving support apparatus 300 executing a program prepared in advance.

  First, the awakening effect control unit 105 determines whether or not the user has performed an input operation related to a scent generation request (step S21), and when there is an input operation related to a scent generation request (step S21; Yes). Then, a scent generation request is made to the scent generating device 80, and the scent generating device 80 generates a scent (step S22).

  Then, the awakening effect control unit 105 refers to the current location information acquired by the current location information acquisition unit 101 and determines whether or not the vehicle has stopped for 1 minute or longer (step S23), and the vehicle has stopped for 1 minute or longer. If it is present (step S23; Yes), a scent generation request is made to the scent generating device 80, and the scent generating device 80 generates a scent (step S24).

  Then, the awakening effect control unit 105 determines whether or not there is an acceleration of 0.3 G or more in the traveling direction based on the information provided by the autonomous positioning device 10 or the like (step S25), and 0.3 G or more in the traveling direction. If there is an acceleration (step S25; Yes), a scent generation request is made to the scent generating device 80, and the scent generating device 80 generates a scent (step S26).

  Then, the awakening effect control unit 105 determines whether or not the number of times of traveling within 20 km / h is 50 or more using the information acquired from the autonomous positioning device 10 or the GPS receiver 18 (step S27). ) When the number of times of traveling within 20 km / h is 50 or more (step S27; Yes), the scent generator 80 is requested to generate a scent, and the scent generator 80 generates a scent ( Step S28).

  Then, when the control is terminated due to power-off or the like (step S29; Yes), the scent request control process is terminated.

  As described above, the awakening effect control unit 105 generates a scent only when a predetermined event (an input by a user, a change in the behavior state of the vehicle, or the like) occurs, so that a scent is frequently generated. Therefore, it is possible to avoid the amount of the fragrance attached to the air tube or the like from increasing, and the attached fragrance from volatilizing to generate fragrance unnecessarily.

  In addition, as described above, uncomfortable situations such as before an intersection, before a crossing, and a traffic jam are set as the timing for generating a scent. When passengers are experiencing pain in the above situation, they feel a mental burden from the time they approach the point. The smell has a characteristic that is remembered in the brain with the experience at that time. In an unpleasant scene, when combined with a pleasant experience of fragrance, the memory is rewritten. Thereby, the scent generation apparatus 80 can be expected to eliminate the unpleasant image scene in daily driving.

  Further, the driving support device 300 presents a setting screen (not shown) and the like to determine whether or not to generate a scent for the predetermined event described above, and which scent is good if generated (for example, mint, It is also possible to allow the user to select from three types of eucalyptus and ylang ylang. In this case, it can be realized by the system controller 20 of the driving support apparatus 300 functioning as a scent setting unit that presents a setting screen, holds a setting content of the user, and the like. The scent setting means may be configured to set the event.

  Thereby, the driving assistance apparatus 300 can make a user determine the definition of the event of fragrance generation | occurrence | production object, and the kind of fragrance to generate.

  According to the above configuration, in the in-vehicle scent generating device, the scent generating means for generating scent, the scent injecting means for injecting the scent generated by the scent generating means to the outside, and the scent controlling means for controlling the scent generation The scent generating means is disposed in a predetermined light shielding space.

  In the scent generating device, the scent generating means generates scent in accordance with the control by the scent controlling means, and the scent emitting means provides the scent by injecting the scent to the outside. And the said fragrance production | generation means is arrange | positioned in the predetermined cool and dark place.

  In this way, the scent generating device has the scent generating means having the fragrance arranged in a cool and dark place (inside the trunk room, etc.), so that the fragrance can be prevented from being altered by direct sunlight, Further, it is possible to prevent leakage of odors and to prevent the operation sound from being transmitted to the driver or the like.

  Arranging the main body 87 for generating a scent in the light-shielding space as described above also has an effect of preventing denaturation of the essential oil. The components of essential oils are organic compounds, and chemical reactions such as oxidation occur depending on light and temperature, and the components may be denatured. As is known in the field of aromatherapy, essential oil components have various physiologically active effects on humans and contain many components that purify air such as sterilization and antibacterial. Here, the types of essential oils and their component compositions are very important, but if this component is denatured, the expected effect cannot be obtained. In this sense, it is a great advantage not to expose the essential oil to light or to be exposed to high temperatures.

  In addition, there is an effect of shielding odor leakage into the passenger compartment and shielding the operation sound of the main body 87. When the main body 87 of the scent generating device 80 is disposed in the passenger compartment, there is no fear that the fragrance in the tank 85 will be spilled by a passenger such as a child. Even if the fragrance is spilled, if the main body 87 is located in the spare tire storage section or the like, the scent generating device 80 can minimize the influence on the passenger compartment due to the leakage of the scent.

  In addition, the fragrance | flavor shall be contained in the cartridge. Solid (beads, powders, gels) fragrances may be used to prevent liquid leakage due to vehicle vibrations. The trunk room often contains food and the like, and it is effective to prevent odor leakage by solidifying the fragrance. When replacing the same fragrance, replace the cartridge. When changing to another fragrance, replace the cartridge and air tube.

  The cartridge information is transmitted to the scent control unit 81. The information on the cartridge includes information necessary for management, such as the name of the fragrance substance, the remaining amount of the fragrance substance, and the start date of use. The CPU 22 can also notify the user of a cartridge replacement notice using information about the cartridge.

  In the scent generating device 80, it is desirable to arrange a plurality of air tubes 83 in parallel according to the number of types of fragrances. Thereby, in the scent generator 80, it can avoid that a scent mixes. Further, the material of the air tube 83 is preferably a Teflon material in that the adhesion of aromatic molecules is small.

  The blower 86 sucks up air in the container 88 and sends out the air in the injection direction. In order to suck up air, the container 88 is formed with a clearance hole. Thereby, the scent generator 80 can avoid that the air | atmosphere in a container falls and a wind does not come out because a container 88 does not have a clearance hole.

  The driving support device 300 may inject a deodorant in a certain amount in order to remove the scent (fragrance molecules) remaining in the air tube 83C after the scent has been generated for a predetermined time. In this case, the driving assistance apparatus 300 can prevent mixing with the previous scent when injecting another scent by injecting the deodorant.
