This is a transmission type display unit that forms an image of the above-mentioned various vehicle information, and includes a main display unit 110A and a sub display unit 110B.

  The main display portion 110A is a display portion that mainly displays driving information and warning information in the vehicle information, and includes a mortar-shaped surface portion 111 and a flat surface portion 112. The mortar-shaped surface portion 111 is, for example, a display surface portion that extends from a horizontally long elliptical outer peripheral portion so as to be constricted in a mortar shape toward the front side (back side) of the driver. That is, the mortar-shaped surface portion 111 is a curved surface corresponding to a conical circumferential surface with a tip portion cut. An elliptical outer peripheral portion on the near side with respect to the driver of the mortar-shaped surface portion 111 is connected to an opening portion of the dashboard 10.

  The flat surface portion 112 is a display surface portion disposed at a cut portion of the mortar-shaped surface portion 111. That is, the flat surface portion 112 is formed in a flat shape at the tip of the mortar-shaped surface portion 111 so as to face the driver. The flat surface portion 112 is set at a position recessed from the opening of the dashboard 10 via the mortar-shaped surface portion 111. Here, the flat portion 112 is formed in a circular shape.

  The sub display part 110B is two display surface parts formed so as to be opposed to the driver (like fins) from the left and right positions of the elliptical outer peripheral part of the mortar-shaped surface part 111 toward the outside, for example. . The sub-display unit 110B is disposed on the outer peripheral portion of the mortar-shaped surface portion 111 so as to face each other in the left-right direction, and is connected so as to form one surface with respect to the front surface portion 10a at the opening of the dashboard 10. Has been. The front surface portion 10a corresponds to the mounting surface of the present invention.

  The screen 110 is arranged so that the main display portion 110A is substantially within the upper half region of the steering wheel 20 in the vehicle driver's seat as viewed from the driver, and the sub display portion 110B is located on the upper half portion of the steering wheel 20. It arrange | positions so that it may become an outer side. And in the screen 110, the plane part 112 is located in the substantially center.

  For example, the vehicle speed, the gear position, the fuel remaining amount, and the like as travel information are displayed on the flat surface portion 112 (not shown). Further, as shown in FIG. 3, at a predetermined position of the mortar-shaped surface portion 111, for example, the display positions 111a to 111d on the left and right surfaces, as other travel information, engine water temperature, engine speed, travel distance, average fuel consumption, etc. Is displayed. Further, when warning information is generated, the warning information is displayed at another position of the mortar-shaped surface portion 111, for example, the display position 111e. Furthermore, ambient information is displayed on the sub display unit 110B and the plane unit 112. Details of the display of the ambient information will be described later.

  The projector 120 is a projector that projects an optical image corresponding to various types of vehicle information onto the screen 110, and is disposed in the dashboard 10 further on the back side (back side as viewed from the driver) than the screen 110. ing. The projector 120 is composed of, for example, a liquid crystal projector including a liquid crystal panel and a light source that transmits and illuminates the liquid crystal panel. The contents of the optical image formed by the projector 120 are controlled by the control unit 130 described later.

  The control unit 130 is a control unit that controls display contents of vehicle information on the screen 110. Specifically, the control unit 130 determines the content of the current travel information based on various detection signals obtained from various sensor groups 140 described later, causes the projector 120 to form the determined travel information as an optical image, Further, when warning information is generated, the warning information is formed in the projector 120 as an optical image. Further, the control unit 130 determines the ambient information based on the selection signal from the mode change switch, the operation signal from the vehicle device, and the detection signal from the proximity sensor or the like, and optically transmits the determined ambient information to the projector 120. It is designed to form as an image.

  The various sensor group 140 detects a detection signal related to vehicle information, and generates a detection signal related to travel information. For example, a vehicle speed sensor, a gear sensor, a fuel sender, an engine water temperature sensor, and an engine speed There are sensors. Further, there are an engine oil pressure sensor, a brake sensor, a seat belt sensor, a door sensor, a battery sensor, and the like that generate a detection signal related to warning information.

  Next, the operation of the display device 100 based on the above configuration will be described.

  The control unit 130 determines the content of travel information such as the current vehicle speed, gear position, fuel remaining amount, engine water temperature, engine speed, travel distance, average fuel consumption, etc., from various detection signals obtained from the various sensor groups 140. The display content is formed on the projector 120. The projector 120 forms an optical image based on an instruction from the control unit 130 and projects the optical image on the screen 110 (the flat surface portion 112 and the mortar-shaped surface portion 111). The vehicle speed, gear position, fuel remaining amount, and the like are projected onto the flat surface portion 112, and the engine water temperature, engine speed, travel distance, average fuel consumption, and the like are projected onto the mortar-shaped surface portion 111. Further, when the control unit 130 obtains detection signals corresponding to warning information such as engine oil pressure abnormality, brake abnormality, seat belt non-wearing, door lock failure, insufficient charging, etc. from the various sensor groups 140, the warning information is sent to the projector 120. A display is formed and projected onto the screen 110 (conical surface portion 111).

  By displaying very basic information (vehicle speed, gear position, remaining amount of fuel, etc.) among the driving information on the flat surface portion 112 on the far side for the driver, the driver is looking at the front view. The plane portion 112 can be seen without greatly changing the focus of the eyes.

  In addition, other travel information (engine water temperature, engine speed, travel distance, average fuel consumption, etc.) is displayed at the display positions 111a to 111d of the mortar-shaped surface portion 111, and the driver can display these travel information as if they were a plane. It can be seen with a novel image as if drifting in a conical three-dimensional space on the front side from the portion 111. Further, when warning information is generated, the warning information is displayed at the display position 111e, and the driver can view the warning information with the same feeling as other traveling information.

  Here, when the ambient information is generated, the control unit 130 causes the projector 120 to form the ambient information and project the ambient information onto the screen 110. Here, the ambient information is displayed on the two sub display sections 110B by color, and is displayed on the plane section 112 by graphics (or characters).

  The color displayed on the sub display unit 110B is determined in advance according to the content of the ambient information. For example, as shown in FIGS. 3 to 5, the color is green when the eco mode is activated (FIG. 3). ) In addition, when the sport mode is activated, the color is red (FIG. 4), and when the audio voice recognition function is activated, the color is purple (FIG. 5). . The area displayed in color as ambient information is formed in an arc-shaped band shape centering on the plane portion 112 in the sub display portion 110B.

  The graphic displayed on the plane portion 112 is an explanatory display for the color display and is determined in advance according to the content of the ambient information. For example, as shown in FIGS. Is the eco mode icon (green leaf in FIG. 3) 112a, the sport mode icon (checker flag in FIG. 4) 112b in the sport mode, and the voice recognition icon when the voice recognition function is activated with audio. (Microphone in FIG. 5) 112c. Instead of these figures, character displays such as “eco mode”, “sport mode”, and “speech recognition function in operation” may be used.

  In the plane portion 112, the ambient information figure is added to these information while keeping the traveling information such as the vehicle speed, the gear position, and the remaining amount of fuel that were originally displayed. Alternatively, as shown in FIGS. 3 to 5, if there is no room on the plane portion 112, at least one of the traveling information such as the vehicle speed, the gear position, and the remaining amount of fuel is temporarily erased, and the ambient You may make it replace with the figure of information.

  As described above, in the present embodiment, ambient information is displayed in color on the sub display unit 110B, so that the driver looks at the scenery in front of the vehicle or looks inside the main display unit 110A. Even if it is, it can be sensuously and easily grasped that the ambient information has been generated.

  In addition, since an explanatory figure or character corresponding to the color display is displayed on the plane portion 112 which is substantially the center of the screen 110, when ambient information is displayed in color on the sub display portion 110B, the center side When the line of sight is moved to, the figure or character corresponding to the color display can be seen, and the specific information of the ambient information can be confirmed.

  In addition, since the sub display unit 110B is provided at positions (here, left and right positions) facing each other on the outer periphery of the main display unit 110A, the entire screen 110 is designed to be symmetrically balanced. Can do. When the ambient information is displayed in color, color display that wraps the main display portion 110A from both sides is possible, and a novel display effect is possible. Furthermore, by arranging the sub display portions 110B on the left and right, it is possible to easily connect the sub display portion 110B to the front surface portion 10a of the dashboard 10 so as to be one surface.

  In addition, since the outer peripheral portion of the main display portion 110A has an elliptical shape, and the color display area of the ambient information has an arc-shaped band shape centered on the flat portion 112, the overall design should be round and gentle. In addition, it is possible to clarify the positional relationship between the color display of the ambient information and the flat surface portion 112 on the center side. In other words, the relationship between the color display and the explanation display (relationship between the two), such that the explanation can be seen by moving the line of sight toward the center based on the arc-shaped color display (ambient information). Sex) can be clarified.

(Second Embodiment)
