  By the way, a vehicle head-up display device (vehicle HUD device) is usually installed on an instrument panel between a windshield and a steering wheel (steering wheel) so as to display a virtual image in the direction of the driver's line of sight. . Thus, for example, when the handle is installed on the right side of the vehicle, the vehicle HUD device is also installed on the right side of the vehicle, and when the handle is installed on the left side of the vehicle, the vehicle HUD device is also installed on the left side of the vehicle. . Thus, the installation position of the vehicle HUD device depends on the installation position of the handle.

  In addition, since the vehicle HUD device is installed on the instrument panel between the windshield and the handle, the shape of the vehicle HUD device depends on the shape of the instrument panel on the windshield side. The shape of the instrument panel on the windshield side depends on the shape of the windshield, but since the windshield usually has a curved shape, the part on the windshield side of the instrument panel also has a curved shape. Therefore, the vehicle HUD device also has a shape corresponding to the curved surface shape.

  Usually, since the windshield is formed symmetrically, the part on the windshield side of the instrument panel is also formed symmetrically. Therefore, in principle, the shape of the vehicle HUD device arranged on the right side of the vehicle and the shape of the vehicle HUD device arranged on the left side of the vehicle are mirror-symmetric (mirror symmetry). Thus, the shape of the vehicle HUD device is changed according to the installation position.

  By the way, as described above, when the shape of the vehicle HUD device is changed to mirror symmetry according to the installation position, the rotation direction of the motor of the vehicle HUD device arranged on the right side of the vehicle and the left side of the vehicle The rotation direction of the motor of the arranged vehicle HUD device is reversed. For example, in the vehicle HUD device arranged on the right side of the vehicle, when the display position of the virtual image moves upward when the motor rotates in one direction, the vehicle HUD device arranged on the left side of the vehicle Then, when the motor rotates in the same direction, the display position of the virtual image moves downward. For this reason, in the configuration described in Patent Document 1, it is necessary to determine the rotation direction of the motor in advance according to the installation position of the vehicle HUD device (handle). In the case of the configuration described in Patent Document 1, in order to determine the rotation direction of the motor in advance, a dedicated wire harness for connecting the motor and the control device according to the installation position of the vehicle HUD device (handle) Alternatively, a dedicated control device must be prepared. For this reason, the vehicle HUD device disclosed in Patent Document 1 has a problem that the versatility with respect to the installation position of the handle is poor.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a vehicle head-up display device having improved versatility with respect to a handle installation position and a method for manufacturing the same.

  In order to achieve the above-described object, the invention according to claim 1 is directed to a display unit that emits an information image and a windshield so as to display the information image emitted from the display unit as a virtual image to the driver.

Yes, the installation information is written in the memory after being installed in the vehicle.

  Thus, according to the present invention, since the installation information of the steering wheel (steering wheel) is written in the memory after being mounted on the vehicle, the display position of the virtual image is changed according to the steering wheel position of the mounted vehicle. The direction of rotation of the motor is determined. Therefore, the versatility with respect to the arrangement position of the handle is improved as compared with the configuration in which the rotation direction of the motor is determined according to the installation position of the handle before being mounted on the vehicle.

  As described in claim 2, when the steering wheel is installed on the right side of the vehicle, the control unit moves the display position of the virtual image in one direction by rotating the motor in one direction based on the installation information. When the handle is installed on the left side of the vehicle, the display position of the virtual image is moved in one direction by rotating the motor in the other direction.

  As described in [Problems to be Solved by the Invention], the rotation direction of the motor of the vehicle HUD device arranged on the right side of the vehicle, and the rotation direction of the motor of the vehicle HUD device arranged on the left side of the vehicle Reverses. Therefore, as described in claim 2, when the handle (vehicle HUD device) is arranged on the right side of the vehicle, the motor is rotated in one direction, and when the handle is arranged on the left side, the motor is arranged in one direction. The display position of the virtual image can be moved in an appropriate direction by rotating in the other direction, which is the opposite direction.

  According to a third aspect of the present invention, it is preferable to have a first instruction switch for inputting a first instruction signal for rotating the motor in one direction or the other direction to the control unit. According to this, the display position of the virtual image can be adjusted to the position desired by the driver by operating the first instruction switch.

  According to a fourth aspect of the present invention, there is provided a position detection unit that detects position information of at least one of the driver's seat position and the driver's pupil position, and the control unit detects the position information detected by the position detection unit. The motor may be controlled based on the installation information. According to this, the display position of the virtual image can be automatically adjusted according to the driving posture of the driver.

  According to a fifth aspect of the present invention, it is preferable to have a second instruction switch for inputting a second instruction signal for automatically controlling the motor to the control unit based on the position information and the installation information. According to this, by operating the second instruction switch, it is possible to switch whether or not the automatic adjustment of the virtual image display position can be performed.

  According to a sixth aspect of the present invention, a display switch for inputting a display signal for determining whether or not to display a virtual image to the control unit may be provided. According to this, it is possible to select whether or not to display a virtual image by operating the display switch.

  As described in claim 7, the arrangement information of the steering wheel can be input to the control unit from a combination meter mounted on the vehicle. Usually, the combination meter stores handle installation information and product number information such as the country of production. Therefore, as described in claim 7, the installation information of the handle can be acquired from the combination meter.

  In addition, since the effect of the invention of Claim 8 and Claim 9 is the same as that of Claim 1, the description is abbreviate | omitted.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a schematic diagram for explaining a virtual image. FIG. 2 is a perspective view illustrating a schematic configuration of the vehicle head-up display device according to the first embodiment. FIG. 3 is a perspective view illustrating a schematic configuration of the control unit. FIG. 4 is a block diagram of the vehicle head-up display device. FIG. 5 is a front view showing the switch. FIG. 6 is a flowchart showing a process of storing the installation information in the memory.

  A vehicle head-up display device 100 (hereinafter referred to as a vehicle HUD device 100) shown in FIG. 1 includes, as shown in FIGS. 2 and 3, a display unit 10 that emits an information image, and the display unit. 10 includes a reflection unit 20 that reflects the information image emitted from the inner surface of the windshield FG, and a control unit 30 that controls the display unit 10 and the reflection unit 20.

  As shown in FIG. 1, the vehicle HUD device 100 is installed between a windshield FG and a combination meter CM (steering wheel SH) in an instrument panel IP of the vehicle. The information image emitted from the vehicle HUD device 100 is reflected by the inner surface of the windshield FG, and the reflected information image enters the pupil of the driver DV. Thereby, the driver DV recognizes an image formed at a position symmetrical to the pupil as a virtual image VI through the windshield FG. The optical path length from the windshield FG to the virtual image VI is equal to the optical path length from the display unit 10 to the windshield FG, and the display position of the virtual image VI is determined by the optical path length from the display unit 10 to the windshield FG. . In the present embodiment, the combination meter CM (steering wheel SH) is disposed on the left side of the vehicle, and the vehicle HUD device 100 is also disposed on the left side of the vehicle.

  The display unit 10 fulfills a function of emitting an information image. The display unit 10 includes a light source 11 that emits light, and an image display unit 12 in which the light transmittance is variable for each pixel. When light is transmitted through the image display unit 12, a luminance difference for each pixel is formed in the transmitted light. As a result, the light transmitted through the image display unit 12 includes display information such as the vehicle speed. Light including this display information is emitted from the display unit 10 as an information image.

  In addition to the light source 11 and the image display unit 12, the display unit 10 according to the present embodiment includes a plane mirror 13 that reflects light (information image) transmitted through the image display unit 12 to a reflection mirror 21 described later. The light emitted from the light source 11 is emitted to the plane mirror 13 via the image display unit 12, and the light emitted to the plane mirror 13 is reflected by the plane mirror 13 to the reflecting mirror 21. In this way, the light (information image) transmitted through the image display unit 12 is not immediately emitted to the reflecting mirror 21, but is emitted to the reflecting mirror 21 via the plane mirror 13, so that the windshield FG is emitted from the display unit 10. The optical path length up to can be increased. As described above, the display position of the virtual image VI is determined by the optical path length from the display unit 10 to the windshield FG. Accordingly, as described above, the display position of the virtual image VI can be set farther by emitting the information image to the reflecting mirror 21 via the plane mirror 13. Thereby, in order to ensure the optical path length from the display part 10 to the windshield FG (in order to set the display position of the virtual image VI far), it is suppressed that the physique of the vehicle HUD apparatus 100 increases.

  The reflection unit 20 includes a reflection mirror 21 that reflects the information image emitted from the display unit 10 on the inner surface of the windshield FG, and a motor 22 that adjusts the inclination angle of the reflection mirror 21. The reflecting mirror 21 is a concave mirror that reflects and enlarges the information image emitted from the display unit 10 to the windshield FG. The mirror surface 21 a of the reflecting mirror 21 is inclined at a predetermined angle with respect to the bottom of the case 40 described later, and the inclination angle of the mirror surface 21 a is adjusted by the motor 22. The motor 22 is rotatable in both directions, and rotates when the current application direction is the first conduction direction and when the current conduction direction is the second conduction direction opposite to the first conduction direction. The direction is reversed. The energization direction of the current flowing through the motor 22 is controlled by the control unit 30 described later.

  In the present embodiment, when a current in the first energization direction is applied to the motor 22, the motor 22 rotates clockwise (in FIG. 2 in the direction indicated by the alternate long and short dash line in FIG. 2) from the motor 22 toward the reflecting mirror 21. When the motor 22 rotates in the direction indicated by the solid line and a current is applied to the motor 22 in the second energization direction opposite to the first energization direction, the motor 22 rotates counterclockwise (the arrow direction indicated by the broken line in FIG. 2). It is designed to rotate. When the motor 22 rotates clockwise, the inclination angle of the mirror surface 21a of the reflecting mirror 21 increases, and when the motor 22 rotates counterclockwise, the inclination angle of the mirror surface 21a decreases. When the tilt angle of the mirror surface 21a increases, the display position of the virtual image VI rises from the current position, and when the tilt angle of the mirror surface 21a decreases, the display position of the virtual image VI falls below the current position. Therefore, in the present embodiment, when the current in the first energization direction is applied to the motor 22, the display position of the virtual image VI rises from the current position, and when the current in the second energization direction is applied to the motor 22, The display position of the virtual image VI is lowered from the current position.

  As shown in FIG. 3, the control unit 30 includes a plurality of electronic elements 32 mounted on a wiring board 31, and the display unit 10 and the reflection unit 20 are configured by the electronic elements 32 and wiring (not shown) of the wiring board 31. A circuit for controlling the above is configured. The wiring board 31 is provided with a connector 33 for electrical connection with a connection terminal (not shown), and electrical signals are transmitted and received through the connector 33 and the connection terminal.

  As shown in FIG. 4, the control unit 30 according to the present embodiment is electrically connected to the display unit 10, the motor 22, a position detection unit 50 (described later), a switch 60, and a combination meter CM. The display unit 10 and the motor 22 are electrically connected to the control unit 30 via a wire (not shown), and each of the position detection unit 50, the switch 60, and the combination meter CM is connected to the connector 33 and the above. It is electrically connected via a connection terminal. The control unit 30 includes a memory (not shown) that stores installation information indicating whether the installation position of the steering wheel SH included in the product number information held by the combination meter CM is the left side or the right side of the vehicle. Yes. The control unit 30 controls the driving of the motor 22 based on the installation information of the steering wheel SH stored in the memory and the operation of the switch 60. The product number information described above includes a product number, a manufacturing time, a country of production, and the like in addition to information on installation on the vehicle.

  The case 40 accommodates the display unit 10, the reflection unit 20, and the control unit 30. The opening of the case 40 is closed by a cover (not shown) in order to prevent dust such as dust from adhering to the display unit 10 and the reflection unit 20. This cover has translucency, and as shown by a two-dot chain line in FIG. 2, the information image emitted from the display unit 10 is incident on the windshield FG through the cover. The case 40 is formed with a hole 41 for electrically connecting the connector 33 of the control unit 30 and the connection terminal.

  2 does not show the wiring board 31 and the electronic element 32, which are the main components of the control unit 30, but the wiring board 31 is disposed at the bottom of the case 40 and is covered by the plate 42. This is because Thus, by covering the wiring board 31 with the plate 42, the image of the wiring board 31 is prevented from being mixed into the display image.

  The position detection unit 50 detects the seat position of the driver DV and the pupil position of the driver DV. The position detection unit 50 includes a seat position sensor 51 that detects the front / rear position of the driver's seat and the inclination angle of the backrest of the driver's seat, and a camera 52 that detects the position of the driver's DV pupil. Seat position information and driver DV pupil position information detected by the various sensors 51 and 52 are input to the control unit 30.

  The switch 60 is for inputting various instruction signals to the control unit 30. As shown in FIG. 1, the switch 60 is provided on the instrument panel IP on the driver DV side so that the driver DV can operate during driving. As shown in FIG. 5, the switch 60 includes a panel 61 provided with a display switch 62, a changeover switch 63, and a movement switch 64. The display switch 62 determines whether or not to display the virtual image VI. The changeover switch 63 determines whether to adjust the display position of the virtual image VI automatically or manually. The movement switch 64 moves the display position of the virtual image VI in the vertical direction. Hereinafter, a case where each of the various switches 62 to 64 is pressed will be described.

  For example, when the display switch 62 is pressed while the virtual image VI is displayed, a non-display signal for not displaying the virtual image VI is input to the control unit 30 and the virtual image VI is not displayed. On the contrary, when the display switch 62 is pressed in a state where the virtual image VI is not displayed, a display signal instructing display of the virtual image VI is input to the control unit 30 and the virtual image VI is displayed. In this way, by operating the display switch 62, whether or not to display the virtual image VI is selected.

  Further, when the changeover switch 63 is pressed while the display position of the virtual image VI is automatically controlled, a manual switching signal for switching the rotation of the motor 22 to manual is input to the control unit 30. Then, the control part 30 switches to the manual mode which controls the rotation of the motor 22 manually. In this state, when the movement switch 64 described above is pressed, the control unit 30 controls the rotation of the motor 22 based on the installation information and a signal input from the movement switch 64. On the contrary, when the changeover switch 63 is pressed while the display position of the virtual image VI is manually controlled, an automatic switching signal for automatically switching the rotation of the motor 22 is input to the control unit 30. Then, the control part 30 switches to the automatic mode which controls rotation of the motor 22 automatically. In this state, the control unit 30 automatically controls the rotation of the motor 22 based on the installation information and the position information detected by the various sensors 51 and 52. Thus, by operating the changeover switch 63, the control of the display position of the virtual image VI is switched from automatic to manual or from manual to automatic. As described above, since the control unit 30 automatically controls the rotation of the motor 22 based on the installation information and the position information, the display position of the virtual image VI is automatically adjusted according to the driving posture of the driver DV. Is done.

  Further, when the UP switch 64a of the movement switch 64 is pressed in a state where the display position of the virtual image VI is manually controlled, an instruction signal for rotating the motor 22 in a direction to move the display position of the virtual image VI upward is transmitted to the control unit. 30. At this time, the control unit 30 rotates the motor 22 based on the installation information so that the display position of the virtual image VI is located above the current position. On the other hand, when the DOWN switch 64 b of the movement switch 64 is pressed, an instruction signal for rotating the motor 22 in a direction to move the display position of the virtual image VI downward is input to the control unit 30. At this time, the control unit 30 rotates the motor 22 based on the installation information so that the display position of the virtual image VI is positioned below the current position. Thus, by operating the movement switch 64, the display position of the virtual image VI is adjusted to a desired position of the driver DV.

  As described above, in the present embodiment, when the current in the first energization direction is applied to the motor 22, the display position of the virtual image VI rises from the current position, and the current in the second energization direction is applied to the motor 22. Then, the display position of the virtual image VI is configured to be lower than the current position. The controller 30 applies a current in the first energization direction to the motor 22 for the time when the UP switch 64a is pressed, and applies a current in the second energization direction to the motor 22 for the time when the DOWN switch 64b is pressed. Apply. At this time, the control unit 30 applies current to the motor 22 so that the rotation speed of the motor 22 is constant. Further, in the present embodiment, the control unit 30 changes the rotation angle of the motor 22 by a predetermined unit angle when the time when the UP switch 64a or the DOWN switch 64b is pressed is shorter than a predetermined time. Thereby, the user can finely adjust the display position of the virtual image VI in the manual mode.

  Contrary to the present embodiment, the combination meter CM (steering wheel SH) is arranged on the right side of the vehicle, and the vehicle HUD device 100 is also arranged on the right side of the vehicle, that is, the motor 22 When a current in one energizing direction is applied, the display position of the virtual image VI is lowered from the current position. When a current in the second energizing direction is applied to the motor 22, the display position of the virtual image VI is raised from the current position. In the case of the configuration, the control unit 30 applies the current in the second energizing direction to the motor 22 only for the time when the UP switch 64a is pressed, and applies the first current to the motor 22 only for the time when the DOWN switch 64b is pressed. Apply current in the energizing direction.

  The movement switch 64 described above corresponds to the first instruction switch described in the claims, and the instruction signal corresponds to the first instruction signal described in the claims. The changeover switch 63 described above corresponds to the second instruction switch described in the claims, and the changeover signal corresponds to the second instruction signal described in the claims.

  Next, a process of storing the installation information in the memory, which is a feature of the present embodiment, in the method for manufacturing the vehicle HUD device 100 will be described with reference to FIG. In a state where the vehicle HUD device 100 and the combination meter CM are mounted on the vehicle and electrically connected to each other, the control unit 30 turns on the ignition switch IG of the vehicle (Step 10, Yes) and enters the energized state. First, it is confirmed whether or not installation information is written in the memory (step 20). That is, it is confirmed whether or not the memory installation information written flag is on. When the installation information written flag is on, the installation information has already been stored in the memory, and therefore the control unit 30 ends the process shown in the flowchart of FIG. If the installation information written flag is off, the control unit 30 reads installation information included in the product number information held by the combination meter CM (step 30). After reading, the control unit 30 writes the read installation information in the memory (step 40). After the writing, the control unit 30 turns on the memory installation information written flag (step 50), and ends the process.

  Thus, after the vehicle HUD device 100 is mounted on the vehicle, the installation information of the steering wheel SH is written in the memory, whereby the vehicle HUD device 100 is completed. Step 30 described above corresponds to the reading process described in the claims, and step 40 corresponds to the storage process described in the claims. Further, although not described above, before performing step 10, a process of electrically connecting the connection terminals to the connector 33 of the control unit 30 and the connector (not shown) of the combination meter CM is performed. This step corresponds to the connecting step described in the claims.

  Next, the effect of the vehicle HUD device 100 according to the present embodiment will be described. As described above, after the vehicle HUD device 100 is mounted on the vehicle, the installation information of the steering wheel SH is written in the memory. Therefore, the rotation direction of the motor 22 for changing the display position of the virtual image is determined according to the handle position of the vehicle to be mounted. According to this, before mounting the vehicle HUD device on the vehicle, the versatility with respect to the arrangement position of the steering wheel SH is improved as compared with the configuration in which the rotation direction of the motor is determined according to the installation position of the handle. Is done.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  In this embodiment, the control part 30 showed the example which reads installation information from the product number information which the combination meter CM holds, and writes the read installation information to memory. However, the installation information may be input from the external device to the control unit 30 via, for example, an external terminal connected to the vehicle, not from the product number information held by the combination meter CM. The above-described external device gives the vehicle HUD device 100 installation information indicating whether the vehicle HUD device 100 is installed on the right side or the left side of the vehicle. When the installation information is not stored in the memory, the control unit 30 writes the installation information input from the external device in the memory. Then, the written flag of the memory is turned on, and the installation information writing process to the memory is terminated. In addition, when the installation information is written in the memory (the written flag of the memory is turned on), the control unit 30 writes the installation information to the memory even if the installation information is input from the external device. The process ends.
