[0011] A vehicle display device 1 of the present embodiment is mounted on a vehicle 100, such as an automobile. The vehicle display device 1 according to the present embodiment is a measuring device capable of generating a composite display using the real image Ri and the virtual image Vi. The illustrated vehicle display device 1 is arranged in a dashboard 120. For example, the vehicle display device 1 is arranged so that the display image is located above a steering wheel 130 as viewed from the driver.

[0012] As in the Fig. 1 to 3, the vehicle display device 1 according to the present embodiment includes a display device unit U1, a combiner unit U2, a cover unit U3, and a camera 10. The combiner unit U2 and the cover unit U3 are designed according to the vehicle requirements. For example, the display height H and the inclination angle of a Fig. 2 is determined according to the shape of the instrument panel 120, the position of the steering wheel 130, and the like. For example, the position and shape of a cover 62 of the cover unit U3 are determined depending on the display height H and the inclination angle of the combiner 5. The display height H may be the height of the combiner 5 in the vertical vehicle direction Z or the height of the combiner 5 in the vertical image direction GV when viewed from the eye point EP.

[0013] As described below, in the vehicle display device 1 of the present embodiment, the display device unit U1 can be made common with the combiner unit U2 and the cover unit U3 having different specifications. Therefore, it is possible to reduce the number of design steps in the vehicle display device 1.

[0014] As in Fig. 3, the display device unit U1 includes a housing unit 6, an image display device 3, a reflection element 4, a motor 8, and a control unit 9. The housing unit 6 is housed in the instrument panel 120. The shape of the housing unit 6 is cylindrical with a bottom and open at the top. The housing unit 6 is made of a material with light-shielding properties. The opening of the housing unit 6 is closed by the cover unit U3.

[0015] The cover unit U3 consists of a cover part 60 and the cover 62. The cover part 60 is connected to the housing unit 6 to form an accommodation space. The cover part 60 has a through hole 61. The cover 62 is arranged in the through hole 61 and closes the through hole 61. The through hole 61 is located closer to the rear side X2 than the image display device 3, that is, closer to the eye point EP. The cover 62 is a transparent member made of, for example, resin. The shape of the cover 62 is a curved shape curved toward the inside of the housing unit 6. The cover 62 is shaped to reflect external light toward the light-shielding wall. For example, the cover 62 reflects external light transmitted through a windshield 110 toward the wall surface of a hood part 7 or in a direction other than that of the eye point.

[0016] In the following description, a front side in the vehicle longitudinal direction X is referred to as "front side X1" and a rear side in the vehicle longitudinal direction X is referred to as "rear side X2." An upper side in the vehicle vertical direction Z is referred to as "upper side Z1" and a lower side in the vehicle vertical direction Z is referred to as "lower side Z2." The vertical direction of the image displayed by the vehicle display device 1 corresponds to the vertical direction Z of the vehicle.

[0017] The image display device 3 is a device that displays an image, and is, for example, a liquid crystal display device such as a thin-film transistor liquid crystal display (TFT-LCD). The image display device 3 includes a backlight unit and outputs display light by light from the backlight unit. As shown in Fig. As shown in Figure 3, the image display device 3 includes an upper display region 30u and a lower display region 30d. The upper display region 30u and the lower display region 30d are light-emitting regions for emitting display light. The upper display region 30u is located on the upper side Z1 of a display surface 30 of the image display device 3. The lower display region 30d is located on the lower side Z2 of the display surface 30.

[0018] The image display device 3 is arranged so that the upper display area 30u faces the eye point EP.

[0019] The image display device 3 is, for example, attached to the housing unit 6 and held by the housing unit 6. As shown in Fig. As shown in Fig. 3, the housing unit 6 supports the lower display portion 30d and holds the image display device 3. The image display device 3 is arranged at the end portion of the housing unit 6 toward the front side X1, and the display surface 30 is oriented toward the rear side X2. The upper display portion 30u protrudes upward from the housing unit 6.

[0020] The reflection element 4 is arranged inside the housing unit 6. The reflection element 4 is arranged at the end portion of the housing unit 6 toward the rear side X2 and faces the lower display area 30d. The reflection element 4 is, for example, a flat mirror.

[0021] The reflection element 4 of the present embodiment is rotatably supported. The rotation direction of the reflection element 4 is a direction in which the inclination angle of the reflection element 4 is changed with respect to the vehicle vertical direction Z, as indicated by an arrow AR1 in Fig. 3. The reflection element 4 is rotatable within a predetermined range. The predetermined range can be, for example, an angular range of 10 [°]. The motor 8 rotates the reflection element 4 to adjust the inclination angle of the reflection element 4 to a desired angle. The motor 8 is, for example, a stepper motor.

[0022] The control unit 9 controls the image display device 3 and the motor 8. The control unit 9 is, for example, a computer with a processing unit, a memory, a communication interface, and the like. The control unit 9 controls the motor 8 and the image display device 3, for example, according to a prestored program. The vehicle display device 1 preferably includes a non-volatile memory in which various data and programs are stored.

[0023] The camera 10 images a driver 200 and detects the position of the eye point EP. The illustrated camera 10 is arranged at the top center (or left and right, etc.) in the meter display unit and is installed so that it can image the driver 200. The position of the eye point EP in the vehicle vertical direction Z is determined by image recognition on the image generated by the camera 10. The camera 10 can calculate the position of the eye point EP in the vehicle width direction. The camera 10 can output a coordinate value of the detected eye point EP.

[0024] The combiner unit U2 is connected to the display device unit U1. The combiner unit U2 includes the combiner 5 and a hood part 7. The hood part 7 has a light-shielding property and covers the upper display area 30u from the front and top of the vehicle. The hood part 7 can be attached to the receiving unit 6. The upper display area 30u of the image display device 3 is housed in an interior space 70 of the hood part 7. The hood part 7 is shaped to shield the upper display area 30u from external light.

[0025] The combiner 5 is arranged to cover the inner space 70 of the hood part 7. That is, the combiner 5 is arranged to cover the inner space 70 as viewed from the eye point EP. The combiner 5 can be attached to the housing unit 6 or to the hood part 7. The upper display area 30u of the image display device 3 is located behind the combiner 5 as viewed from the eye point EP. In other words, the combiner 5 is arranged closer to the eye point EP than the upper display area 30u.

[0026] The combiner 5 consists of, for example, a half mirror. The combiner 5 is a reflection element capable of transmitting light incident on the back side and reflecting light incident on the front side. The combiner 5 has a reflection surface 5a facing the eye point EP. The reflection surface 5a is arranged on a front side of the combiner 5, the front side facing the eye point EP, or on a back side opposite the eye point EP. The reflection surface 5a may be subjected to a coating or the like to reflect light toward the eye point EP. A reflection-suppressing portion 5b is provided on the back side of the combiner 5. The reflection-suppressing portion 5b suppresses the reflection of the display light of the upper display area 30u toward the front side X1.The reflection suppressing portion 5b may be a surface treatment for suppressing reflection on the combiner 5 or a film attached to the combiner 5.

[0027] As in Fig. 3, the reflection element 4 faces the reflection surface 5a of the combiner 5 via the through hole 61 of the cover unit U3 arranged therebetween. As shown in Fig. As shown in Figure 4, the reflection element 4 reflects the display light Lt output from the lower display area 30d toward the combiner 5. The reflection surface 5a of the combiner 5 reflects the display light Lt in the lower display area 30d toward the eye point EP. The virtual image Vi visually recognized at the eye point EP is formed at a position on the front side X1 relative to the reflection surface 5a. The virtual image Vi is a virtual image of the lower display area 30d and includes an image displayed in the lower display area 30d.

[0028] The projection position of the indicator light Lt on the combiner 5 changes depending on the inclination angle of the reflection element 4. As the inclination angle of the reflection element 4 increases, the projection position of the indicator light Lt on the combiner 5 moves upward. Conversely, as the inclination angle of the reflection element 4 decreases, the projection position of the indicator light Lt on the combiner 5 moves downward.

[0029] As in Fig. 2, the vehicle display device 1 according to the present embodiment performs composite display with a real image Ri and a virtual image Vi. The real image Ri is an image displayed in the upper display area 30u of the image display device 3. The display light of the upper display area 30u is transmitted toward the eye point EP through the combiner 5. The virtual image Vi is a virtual image generated by the display light Lt in the lower display area 30d. That is, the virtual image Vi is an image visually recognized by the display light Lt reflected toward the eye point EP by the reflection member 4 and the combiner 5. The virtual image Vi is displayed above the real image Ri in the vertical image direction GV.

[0030] A display area 51 of a display is provided at one end of the combiner 5 in the image side direction GH. The display of the display is realized, for example, by a display device arranged behind the display area 51.

[0031] In the vehicle display device 1 of the present embodiment, various combiner units U2 can be connected to the common display device unit U1. To cope with the combiner units U2 with different specifications, the control unit 9 of the present embodiment is configured to adjust a display position of an image in the lower display area 30d. As shown in Fig. 5, the upper display area 30u and the lower display area 30d are different areas on the display surface 30. An area between the upper display area 30u and the lower display area 30d is covered, for example, with a mask element or mask print. In the lower display area 30d, a display area 30v is defined in the vertical image direction GV. The display area 30v is an area used for image display for the virtual image Vi in the lower display area 30d. The indicator light Lt in the lower display area 30d is output from the display area 30v. The height W1 of the display area 30v is smaller than the height W0 of the lower display area 30d. That is, the control unit 9 displays an image in the display area 30v that is part of the lower display area 30d. Fig. The display area 30v shown in Figure 5 is located at the center of the lower display area 30d in the vertical image direction GV. As described below, the display device unit U1 of the present embodiment can be combined with any one of the plurality of combiner units U2 having different display heights H.

[0032] Fig. 6 to 8 show three combiner units U2 with different display heights H. The display height H of the combiner unit U2 in Fig. 6 has a value of H1. The display height H of the combiner unit U2 in Fig. 7 has a value of H2, and the value H2 is smaller than the value H1. The display height H of the combiner unit U2 in Fig. 8 has a value of H3, and the value H3 is smaller than the value H2. That is, the display height H of the combiner unit U2 in Fig. 6 is relatively largest, and the display height H of the combiner unit U2 in Fig. 8 is relatively the smallest.

[0033] For example, the control unit 9 sets the display area 30v in the lower display area 30d depending on the display height of the combiner 5.

[0034] The display range 30v is set, for example, based on a setting value stored in the non-volatile memory. As described below, the setting value is determined so that a range in which the optical path of the display light Lt can be adjusted by the up-and-down rotation of the reflection element 4 can be appropriately linked to a required optical path range determined from the eye range ER of the vehicle 100.

[0035] Fig. Fig. 9 shows an optical path of the indicator light Lt in a standard state in which the display area 30v is not optimized for the combiner unit U2. The display area 30v in the standard state is, for example, a center position in the lower display area 30d. The rotational position of the reflection element 4 in Fig. 9 is a neutral position in a rotatable predetermined range.

[0036] The neutral position is a position in which rotation by the same angle is possible both clockwise and counterclockwise.

[0037] Fig. 9 shows the eye area ER, the upper end position EPu, and the lower end position EPd of the vehicle 100. The eye area ER is a statistical representation of the distribution of the driver's eye positions and is a range along the vehicle width direction and the vehicle vertical direction Z. The relative position of the eye area ER with respect to the vehicle display device 1 may vary depending on the vehicle type or the like. The upper end position EPu is the position of the eye point EP at the upper end of the eye area ER. The lower end position EPd is the position of the eye point EP at the lower end of the eye area ER.

[0038] The Fig. The optical path of the indicator light Lt shown in Figure 9 corresponds to the eye point EP, which is closer to the lower end position EPd than the center of the eye area ER. Such a condition occurs, for example, in the Fig. 6 shown combiner unit U2. The combiner unit U2 in Fig. 6 has a large display height H. In this case, the projection position of the display light Lt on the combiner 5 in the standard state is slightly lower than the optimal position.

[0039] Fig. 10 shows the for the combiner unit U2 of Fig. 6 optimized display range 30v. The control unit 9 sets the display range 30v based on the setting value read from the non-volatile memory. The display range 30v in Fig. 10 is set above the center of the lower display area 30d in the vertical image direction GV. Fig. 11 shows an optical path of the display light Lt corresponding to the display area 30v of Fig. 10. In Fig. 11, the rotational position of the reflection element 4 is a neutral position. The optical path of Fig. 11 corresponds to the eye point EP in the center of the eye area ER. In other words, when viewed from the eye point EP in the center of the eye area ER, the virtual image Vi is displayed in a suitable position with respect to the real image Ri, as shown in Fig. 6. In the present specification, such a projection position of the display light Lt is referred to as a “reference position”.

[0040] The reference position is a projection position of the display light Lt on the combiner 5 and is such a position that the position of the virtual image Vi is optimized when viewed from the eye point EP in the center of the eye area ER. When the projection position is the reference position, it is possible to optimize the projection position with respect to each eye point EP by rotating the reflection member 4 by the motor 8. That is, the motor 8 can rotate the reflection member 4 to a position corresponding to the eye point EP for all eye points EP from the upper end position EPu to the lower end position EPd. In other words, the position of the virtual image Vi can be optimized by the motor 8 for all eye points EP of the eye area ER.

[0041] Fig. Fig. 12 shows an optical path of the indicator light Lt in a standard state with respect to the combiner unit U2 of Fig. 8. The combiner unit U2 in Fig. 8 has a low display height H. In this case, the projection position of the indicator light Lt on the combiner 5 in the standard state is a position slightly above the optimal position.

[0042] Fig. 13 shows the display range 30v, which for the combiner unit U2 of Fig. 8 has been optimized. The control unit 9 sets the display range 30v based on the setting value read from the non-volatile memory. The display range 30v in Fig. 13 is set below the center of the lower display area 30d in the vertical image direction GV. The projection position of the display light Lt on the combiner 5 is set to the reference position by such a display area 30v.

[0043] In the combiner unit U2 of Fig. 7, the projection position of the indicator light Lt on the combiner 5 is the reference position when the display area 30v is located in the center of the lower display area 30d. Therefore, the setting value for the vehicle display device 1 with the combiner unit U2 is Fig. 7 a value with the display range 30v as the center position in the vertical image direction GV.

[0044] As described above, the control unit 9 adjusts the display position in the vertical image direction GV in the lower display area 30d so that the projection position of the display light on the combiner 5 is set as the reference position in a state where the rotational position of the reflection member 4 is set as the neutral position. As a result, the display position of the virtual image Vi can be adjusted by the motor 8 according to the position of the driver's eye 200 for both the upper side Z1 and the lower side Z2 in the vehicle vertical direction Z. The control unit 9 rotates the reflection member 4 by the motor 8 based on the coordinate value of the eye point EP acquired by the camera 10. The rotation amount of the motor 8 at this time is determined based on, for example, a table stored in advance.The table can be a unique table corresponding to the product number of the combiner unit U2.

[0045] The step of storing the setting value of the display range 30v in the vehicle display device 1 is performed, for example, in a factory that manufactures the vehicle display device 1. In this case, the setting value of the display range 30v is preferably set in advance for each of the combiner units U2 with different product numbers. For example, the Fig. 6 to 8 have different product numbers, and the setting values of the display areas 30v are different from each other. In this case, the vehicle display device 1 is preferably shipped in a state where the setting value optimized for the combiner unit U2 is stored. The control unit 9 of the vehicle display device 1 sets the display area 30v based on the setting value according to the combiner 5 mounted on the display device unit U1. The step of storing the setting value may be performed after the vehicle display device 1 is mounted on the vehicle 100. In this case, the setting value is determined by the operator, for example, and stored in the memory. Such a setting method is effective when the same combiner unit U2 is mounted for different vehicle types.

[0046] As described above, the vehicle display device 1 according to the present embodiment includes the display device unit U1 and the combiner unit U2. The display device unit U1 includes the image display device 3, the housing unit 6, the reflection element 4, the motor 8, and the control unit 9. The image display device 3 has the upper display portion 30u and the lower display portion 30d for displaying an image, and is arranged so that the upper display portion 30u faces the eye point EP of the vehicle 100. The housing unit 6 houses the lower display portion 30d and opens upward. The reflection element 4 is housed in the housing unit 6 and can be rotated within a predetermined range. The motor 8 rotates the reflection element 4. The control unit 9 controls the image display device 3 and the motor 8.

[0047] The combiner unit U2 consists of the hood part 7 and the combination unit 5. The hood part 7 covers the upper display area 30u from the front of the vehicle. The combiner 5 is arranged closer to the eye point EP than the upper display area 30u. The reflection member 4 is arranged closer to the eye point EP than the lower display area 30d and the combiner 5, and reflects display light Lt in the lower display area 30d to the combiner 5. The rotation direction of the reflection member 4 is a direction in which the projection position of the display light Lt is changed in the vehicle vertical direction Z. The control unit 9 adjusts the display position of the image in the vertical image direction GV in the lower display area 30d according to the combiner 5 mounted on the display device unit U1.In the vehicle display device 1 of the present embodiment, the display device unit U1 can be used together with various combiner units U2.

[0048] The installation state of the vehicle display device 1 on the vehicle 100 varies depending on the vehicle type. The hood part 7 and the combiner 5 are individually designed depending on the installation conditions. Under such conditions, if the housing unit 6 and the reflection element 4 are individually designed to adjust the virtual image display depending on the installation position, a large number of man-hours are required for the design. On the other hand, in the vehicle display device 1 of the present embodiment, the display area for the virtual image Vi in the image display device 3 is set wide, and the display area 30v is adjusted up and down. As a result, the display device unit U1 including the housing unit 6, the reflection element 4, and the motor 8 is commonly used.

[0049] The control unit 9 of the present embodiment adjusts the display position of the image in the vertical image direction GV in the lower display area 30d so that the projection position of the display light Lt on the combiner 5 is set to a predetermined reference position in a state where the position of the reflection element 4 in the rotation direction is set to the neutral position. Therefore, the vehicle display device 1 of the present embodiment can realize a suitable projection position for various combiners 5.

[0050] The reference position of the present embodiment is a position where the projection position of the indicator light Lt on the combiner 5 is optimized with respect to the center position in the vehicle vertical direction Z in the eye area ER. Therefore, the projection position can be adjusted by the motor 8 within a wide range in the vertical direction.

[0051] The vehicle display device 1 of the present embodiment includes the cover unit U3 that closes the opening of the housing unit 6. The cover unit U3 includes the lid part 60 and the transparent cover 62. The lid part 60 has the through-hole 61 and is connected to the housing unit 6. The cover 62 is disposed in the through-hole 61. The display light Lt reflected by the reflection member 4 is transmitted through the cover 62 and projected onto the combiner 5. With such a configuration, the optimal cover 62 can be combined with the combiner unit U2. The cover 62 can be shared with the plurality of combiner units U2. In this case, the cover 62 and the lid part 60 can be included in the display device unit U1. [Modification of the embodiment]

[0052] The control unit 9 can adjust the height of the display area 30v depending on the combiner unit U2. For example, the display area 30v for the combiner unit U2 can be set with a large display height H, as shown in Fig. 6. For a combiner unit U2 with a small display height H, as shown in Fig. 8, the display range can be reduced by 30v.

[0053] When adjusting the projection position of the indicator light Lt corresponding to the eye point EP, the control unit 9 can change both the rotation position of the reflection element 4 and the display range 30v. For example, if there is an eye point EP whose projection position cannot be optimized only by rotating the reflection element 4, the display range 30v can be changed.

[0054] The contents disclosed in the above embodiments and modifications can be combined and implemented as appropriate.
