First, the control unit 41 identifies the vehicle seat 10 in which the user is not seated from the detection of the seat sensor 15 of each vehicle seat 10 (step S1).
Then, the threshold value of the odor detection value prepared in the storage unit 44 for performing deodorization is compared with the detection value of the odor sensor 30 of the vehicle seat 10 in which the user is not seated (step S3). ..
When a plurality of odor sensors 30 are provided for one vehicle seat 10, comparison is performed based on the highest detection value among the plurality of odor sensors 30.
As a result, the control unit 41 ends the operation control when there is no vehicle seat 10 whose detection value of the odor sensor 30 is equal to or higher than the threshold value.

On the other hand, when there is a vehicle seat 10 in which the detected value of the odor sensor 30 is equal to or higher than the threshold value, the odor level of the detected value of the odor sensor 30 of the vehicle seat 10 is determined (step S5).
The odor level is a category of detected values determined stepwise within a range in which the detected value is equal to or higher than the threshold value. The level is determined by which category the numerical range of the detected odor belongs to.
The storage unit 44 is provided with table data that defines the injection amount (injection time) of the deodorant to be executed for each odor level. In this table data, the higher the detection value of the odor defined in the odor level, the larger the injection amount of the deodorant (the longer the injection time) is set.
The control unit 41 determines the odor level with reference to the table data.
Also in this case, when a plurality of odor sensors 30 are provided for one vehicle seat 10, the odor level is determined based on the highest detection value.

Then, the control unit 41 sets the pressure supply device 22 so that the deodorant is injected from the injection port 21 corresponding to the vehicle seat 10 for the vehicle seat 10 whose detection value of the odor sensor 30 is equal to or higher than the threshold value. Controlled, the deodorant is sprayed at the spraying time according to the odor level (step S7), and the operation control is terminated.

[Operation control of deodorant injection device (2)]
FIG. 7 is also a flowchart showing the operation control of the deodorant injection device 20 which is repeatedly executed in a short cycle while the vehicle is in use. However, this operation control is executed with priority over the operation control of FIG. 6 when the engine stop of the vehicle is detected.

The control unit 41 acquires engine drive information from the control device of the control system of the vehicle drive system through the communication unit 45, and determines whether or not the engine has been stopped (step S11).
Then, when it is determined that the engine is not stopped, the operation control is terminated.

On the other hand, when it is determined that the engine has been stopped, the control unit 41 accesses the vehicle management system 47 from the communication unit 45 through the communication network N (step S13).
Then, the control unit 41 determines from the usage schedule data of the vehicle whether the vehicle is in the end-of-use state or the return state (step S15).
Then, if the vehicle does not fall under either the end-of-use state or the return state, the process is returned to step S11, and the engine stop determination is made.

On the other hand, when the vehicle falls under either the end-of-use state or the return state, the control unit 41 determines whether or not all seat deodorization settings have been made in the storage unit 44 (step S17). ..
The all-seat deodorization setting determines whether to deodorize all vehicle seats 10 or only vehicle seats 10 having an odor level equal to or higher than the threshold value when the vehicle engine is stopped. It is the setting data. The setting can be set in advance from the input unit 42. Further, the above settings may be recorded in advance in data such as usage schedule data held by the management system 47, and the above settings may be read and determined.

When all seat deodorant settings are set for the vehicle, the control unit 41 is a pressure supply device so that the deodorant is injected from all the injection ports 21 to all the vehicle seats 10. 22 is controlled, the deodorant is sprayed at the specified spraying time (step S19), and the operation control is terminated.

On the other hand, when the deodorization setting for all seats is not set for the vehicle, the control unit 41 sets a threshold value between the detection value of the odor sensor 30 of all the vehicle seats 10 and the detection value of the odor to be deodorized. In comparison with the above, it is determined whether or not there is a vehicle seat 10 to be deodorized (step S21). Also in this case, when a plurality of odor sensors 30 are provided for one vehicle seat 10, comparison is performed based on the highest detection value.
Then, when the vehicle seat 10 to be deodorized does not exist, the operation control is terminated.

If there is a vehicle seat 10 to be deodorized, the odor level of the detected value of the odor sensor 30 of the vehicle seat 10 is determined (step S23). The odor level is as described above.
The control unit 41 determines the odor level with reference to the above-mentioned table data.
Then, the control unit 41 sets the pressure supply device 22 so that the deodorant is injected from the injection port 21 corresponding to the vehicle seat 10 for the vehicle seat 10 whose detection value of the odor sensor 30 is equal to or higher than the threshold value. Controlled, the deodorant is sprayed at the spraying time according to the odor level (step S25), and the operation control is terminated.

[Control for detecting the remaining amount of deodorant]
FIG. 8 is a flowchart showing a deodorant remaining amount detection control that is repeatedly executed in a short cycle while the vehicle is in use.
The control unit 41 determines whether or not the liquid level height of the deodorant in the tank is equal to or lower than the height requiring replenishment by the level sensor 231 provided in the deodorant tank 23 (step S31). ).
As a result, if the liquid level height of the deodorant in the tank has not yet dropped to the height requiring replenishment, the treatment is terminated.

On the other hand, when the liquid level height of the deodorant in the tank has dropped to a height requiring replenishment, the control unit 41 executes the notification process (step S33).
As the notification process, notification to the inside of the vehicle and notification to the outside of the vehicle are performed.
At the time of notification to the vehicle interior, the control unit 41 sends a message or a display requesting the replenishment of the deodorant to the deodorant tank 23 on the display of the output unit 43, and the deodorant container B for replenishment is displayed. Navigate to the user whereabouts of. Further, the voice output means of the output unit 43 may notify the replenishment of the deodorant by voice, or the light emitting means or the vibrator may notify the replenishment of the deodorant.
Further, at the time of notification to the outside of the vehicle interior, the control unit 41 notifies the vehicle management system 47 from the communication unit 45 through the communication network N that the deodorant needs to be replenished.

[Technical effect in the embodiment of the invention]
