When the position of the seat in the vertical direction of the vehicle is on the upper side, there is a high possibility that the occupant seated on the seat is smaller than when the seat is on the lower side. Also, the smaller the physique of the occupant, the lower the eye point of the occupant tends to be. Therefore, it can be said that there is a correlation between the position of the seat in the vertical direction of the vehicle and the height of the eye point of the passenger sitting on the seat.

According to the above configuration, the position of the seat in the vertical direction of the vehicle is used as the state quantity related to the height of the occupant's eye point. As a result, the auxiliary visor can be slid appropriately based on the position of the seat in the vertical direction of the vehicle, which correlates with the height of the occupant's eye point.

<Control of Motor 31 of Sun Visor Device 20 by Visor Control Unit 42>
Here, in order to prevent the direct light from the sun S from entering the eyes of the occupant D seated on the seat 51 through the windshield 13, when the eye point of the occupant D is low, the visor should be larger than when the eye point is high. It is preferable to lower the lower end of the portion 21 .

Therefore, the visor control unit 42 controls the visor D so that the auxiliary visor 23 protrudes downward when the eye point of the occupant D seated on the seat 51 is low (crew DS) compared to when it is high (crew DL). The motor 31 is controlled based on the state quantity related to the height of the eye point of .

When the position of the seat 51 in the front-rear direction L is on the front side, there is a high possibility that the physique of the occupant D seated on the seat 51 is smaller than when it is on the rear side. Further, when the position of the seat 51 in the up-down direction Z is on the upper side, there is a high possibility that the occupant D seated on the seat 51 is smaller than when it is on the lower side.

Also, the smaller the physique of the occupant D, the lower the eye point of the occupant D tends to be.
Therefore, it can be said that there is a correlation between the position of the seat 51 in the longitudinal direction L and the height of the eye point of the occupant D seated on the seat 51 . Further, it can be said that there is a correlation between the position of the seat 51 in the vertical direction Z and the height of the eye point of the occupant D seated on the seat 51 .

Therefore, the visor control unit 42 of the present embodiment detects the position of the seat 51 in the longitudinal direction L detected by the seat longitudinal position detection unit 81 and the position of the seat 51 in the vertical direction Z of the vehicle 10 detected by the seat height position detection unit 82 . The motor 31 is driven based on the position of . Specifically, the visor control unit 42 controls the motor 31 so that the auxiliary visor 23 projects downward when the seat 51 is on the front side compared to when it is on the rear side. Also, the visor control unit 42 controls the motor 31 so that the auxiliary visor 23 projects downward when the seat 51 is on the upper side compared to when it is on the lower side.

Next, a processing procedure for controlling the motor 31 by the seat ECU 40 will be described with reference to the flowchart of FIG.
This series of processes is executed only when the detection unit 35 detects that the visor main body 22 is at the use position.

As shown in FIG. 4 , in this series of processes, first, the seat ECU 40 detects the position of the seat 51 based on the detection results of the seat front-rear position detection unit 81 and the seat height position detection unit 82 . It is determined whether or not the position of 51 has been changed (step S1).

Here, if it is determined that the position of the seat 51 has changed (step S1: "YES"), the seat ECU 40 next changes the position of the seat 51 in the longitudinal direction L and the position of the seat 51 in the vertical direction Z. Detect (step S2).

Next, the seat ECU 40 derives a target value for the amount of protrusion of the auxiliary visor 23 from the lower end surface 22b of the visor body 22 based on the position of the seat 51 in the longitudinal direction L and the position of the seat 51 in the vertical direction Z (step S3).

The seat ECU 40 refers to a map that defines the relationship between the position of the seat 51 in the longitudinal direction L, the position of the seat 51 in the vertical direction Z, and the amount of protrusion of the auxiliary visor 23 from the lower end surface 22b of the visor main body 22. A target value for the projection amount of the auxiliary visor 23 is derived. More specifically, the target value is derived such that the more the seat 51 is located on the front side or the upper side, the more the auxiliary visor 23 protrudes. Note that the seat ECU 40 stores the derived target value in the storage unit. Moreover, the above relationship is set in advance through experiments and the like.

Next, the seat ECU 40 controls the motor 31 based on the derived target value of the protrusion amount (step S4).
Then, the seat ECU 40 ends this series of processes.

On the other hand, when it is determined that the position of the seat 51 has not been changed (step S1: "NO"), the target value is not updated because the height of the eye point of the occupant D has not been changed.

At this time, the seat ECU 40 does not derive the target value of the protrusion amount, and controls the motor 31 based on the previously derived target value of the protrusion amount of the auxiliary visor 23 (step S5). Then, the seat ECU 40 ends this series of processes.

When the detection unit 35 detects that the visor unit 21 has been returned from the use position to the storage position, the seat ECU 40 stores the entire auxiliary visor 23 inside the storage unit 22c of the visor main body 22. It controls the motor 31 .

Next, the operation of this embodiment will be described.
As shown by the solid line in FIG. 5, the direct light from the sun S is blocked by the visor body 22 at the reference position, which is the position of the seat 51 at which the passenger DL of standard build can drive properly. Therefore, the light hardly enters the eyes of the passenger DL.

Also, at this time, as shown by the two-dot chain line in FIG. , incident on the eyes of the passenger DS.

As indicated by the solid line in FIG. 6, the passenger DS with a small physique changes the position of the seat 51 forward and upward from the reference position.
At this time, the motor 31 is controlled by the seat ECU 40 as the position of the seat 51 is changed, so that the auxiliary visor 23 protrudes downward from the lower end surface 22 b of the visor body 22 . As a result, the direct light from the sun S is blocked by the visor main body 22 and the auxiliary visor 23, so that most of the light does not enter the eyes of the passenger DS.

Next, the effects of this embodiment will be described.
(1) The seat ECU 40 adjusts the height of the eye point of the passenger D so that the auxiliary visor 23 projects downward when the eye point of the passenger D sitting on the seat 51 is low compared to when the eye point is high. The motor 31 that constitutes the drive unit 30 is controlled based on the state quantity to be determined.

According to such a configuration, the drive unit 30 is controlled based on the state quantity related to the height of the eye point of the occupant D seated on the seat 51, so that when the height of the eye point of the occupant D is low, the height is high. The auxiliary visor 23 protrudes downward compared to the time. Therefore, it is possible to reduce the trouble of adjusting the protrusion amount of the auxiliary visor 23 .

(2) The sun visor device 20 includes a seat front-rear position detector 81 that detects the position of the seat 51 in the front-rear direction L. As shown in FIG. The seat ECU 40 drives the drive section 30 based on the position of the seat 51 in the front-rear direction L detected by the seat front-rear position detection section 81 . Further, the seat ECU 40 controls the motor 31 so that the auxiliary visor 23 protrudes downward when the seat 51 is on the front side compared to when it is on the rear side.

According to such a configuration, the position of the seat 51 in the front-rear direction L is used as the state quantity related to the height of the occupant D's eye point. As a result, the auxiliary visor 23 can be slid appropriately based on the position of the seat 51 in the longitudinal direction L, which is correlated with the height of the eye point of the occupant D.

(3) The sun visor device 20 includes a seat height position detector 82 that detects the position of the seat 51 in the vertical direction Z. As shown in FIG. The seat ECU 40 drives the drive section 30 based on the position of the seat 51 in the vertical direction Z detected by the seat height position detection section 82 . Further, the seat ECU 40 controls the motor 31 so that the auxiliary visor 23 protrudes downward when the seat 51 is on the upper side as compared to when the seat 51 is on the lower side.

According to such a configuration, the position of the seat 51 in the up-down direction Z is used as the state quantity related to the height of the occupant D's eye point. As a result, the auxiliary visor 23 can be slid appropriately based on the position of the seat 51 in the vertical direction Z, which is correlated with the height of the occupant D's eye point.

(4) The visor main body 22 is provided so as to be movable between the storage position and the use position. The sun visor device 20 includes a detector 35 that detects whether the visor body 22 is at the use position. The seat ECU 40 controls the motor 31 based on the state quantity only when the detection unit 35 detects that the visor body 22 is at the use position.

According to such a configuration, the auxiliary visor 23 is driven to slide only when the visor main body 22 is at the use position. Therefore, when the visor body 22 is in the retracted position, that is, when the occupant D does not use the visor body 22, the auxiliary visor 23 can be prevented from being slid unnecessarily.

<Modification>
This embodiment can be implemented with the following modifications. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

- The auxiliary visor 23 is not limited to being housed inside the visor main body 22 . The auxiliary visor may be slidably connected to the visor body so as to overlap one surface of the visor body.

- The control of the motor 31 may be executed even when the visor section 21 is in the retracted position. In this case, the occupant D may use the visor portion 21 in a state in which the auxiliary visor 23 protrudes from the visor main body 22 in the retracted position, to the use position.

In the above-described embodiment, the target value of the amount of protrusion of the auxiliary visor 23 is derived so that the amount of protrusion of the auxiliary visor 23 increases as the position of the seat 51 is further forward or upward, but the present invention is not limited to this. For example, the auxiliary visor 23 may protrude below the lower end surface 22b of the visor main body 22 only when the seat 51 is positioned forward of a predetermined position in the front-rear direction L. Alternatively, for example, the auxiliary visor 23 may protrude below the lower end surface 22b of the visor body 22 only when the position of the seat 51 is above a predetermined position in the vertical direction Z.

In the above embodiment, the motor 31 is driven based on both the position of the seat 51 in the front-back direction L and the position of the seat 51 in the up-down direction Z, but the configuration is not limited to this. The motor 31 may be driven only based on the position of the seat 51 in the longitudinal direction L, or may be driven only based on the position of the seat 51 in the vertical direction Z.

The state quantity related to the height of the eye point of the occupant D seated on the seat 51 is not limited to the position of the seat 51 . For example, the passenger D may be photographed by an in-vehicle infrared camera, and the height of the eye point of the passenger D may be detected based on the photographed result. In short, when the height of the eye point of the occupant D seated on the seat 51 is low, the auxiliary visor 23 protrudes downward compared to when the eye point is high.
