  • Publication number: 20190235245
    Abstract: In an on-vehicle display device, projection light output from a projecting unit is reflected on an intermediate mirror and is further reflected on a directional mirror. The reflected light is directed to a windshield glass as directed reflected light. In an adjustment operation, the directional mirror is rotated around tilting fulcrum parts by a driving unit to adjust the height of a virtual image formed in front of the windshield glass. In a retracting operation, the lower end of the directional mirror is largely moved forward by the driving unit, rotating the directional mirror with an abutting point between the directional mirror and the upper support acting as a fulcrum. This prevents external light (sunlight) from adversely affecting the projecting unit.

  • Patent number: 10358098
    Abstract: A vehicle speaker system includes a speaker having a diaphragm that generates a sound pressure, a frame that supports the diaphragm vibratably, and a driving unit attached to the frame to drive the diaphragm. A position of the speaker relative to a partition separating a vehicle-cabin inner space and an engine compartment inner space is determined so that the sound pressure generated by an action of the diaphragm passes through an opening in the partition. A shield member is provided with at least a part thereof being located between the speaker and an obstacle generation source located in the engine compartment inner space to obstruct an operation of the speaker. An open part allowing a first space provided between the speaker and the shield member to communicate with the engine compartment inner space is provided in such a direction as not to be directed toward the obstacle generation source.

  • Publication number: 20190222922
    Abstract: An opening portion is formed along an outer peripheral edge of a diaphragm in a second casing portion partitioned by the diaphragm. In the opening portion, a plurality of fins is arranged at regular intervals, and an air passage is formed between every adjacent two of the fins. The fin and the air passage are formed so as to be at an angle to a corresponding imaginary line that extends from the vibration center line of the diaphragm in the radial direction. By forming each of the air passages obliquely, noise generated by an air flow due to sound pressure is reduced.

  • Publication number: 20190204103
    Abstract: A relationship between a relative position with respect to a section where a progressing direction changes on a route and an arrangement height is set such that the arrangement height gradually increases from zero to MaxH. Then, the arrangement height gradually decreases from MaxH to zero along the route from a point on the near side of the section where the progressing direction changes (FIGS. 3B and 3G and FIGS. 4B and 4C). When traveling in the section where the progressing direction changes, a direction mark representing the progressing direction at each point on a road surface is displayed using a heads-up display so as to overlap with a position on an upper side, by an arrangement height set based on a relative position of the point with respect to the section and a set relationship, from the point.

    Abstract: A position in a left-right direction of a display position of a facility figure representing a facility is set to a position overlapping with a virtual line parallel to a traveling lane as viewed from a driver (c). A position in an up-down direction of the display position is determined to be a position overlapping with a road surface on the front side, the position separated upward by H1 from a lower end of a display area of a heads-up display when a distance L from a current position CP to a position TP of a facility is a distance ThL (b1), to be a position separated by H4 (H4<h1) when the distance L is zero, and such that distances H2 and H3 separated upward from the lower end of the display area gradually change from the distance H1 to the distance H4 as the distance L decreases from the distance ThL to zero (b2 and b3). The distance H1 is set such that the facility figure is displayed below a point facing the facility on the road surface on the front side when the distance L is the distance ThL.

  • Publication number: 20190196184
    Abstract: In a display system, a HUD displays a virtual marker D indicating a vehicle shape which guides a traveling direction of a user's vehicle. The display system measures an inter-vehicle distance between the user's vehicle and a forward vehicle and determines a display position and a display size of the virtual marker in accordance with the inter-vehicle distance. The virtual marker is shifted to a near side of the user's vehicle when the inter-vehicle distance is small, whereas the virtual marker is shifted to a far side of the user's vehicle when the inter-vehicle distance is large. A portion of the virtual marker is brought into a non-display state as if the portion is absorbed into the user's vehicle when the inter-vehicle distance is reduced, and the virtual marker is not displayed when the distance is further reduced.

  • Publication number: 20190182435
    Abstract: When a vehicle stops due to a red light, an image of a scene viewed from a virtual point of view, which moves along a virtual point-of-view moving route, in a virtual line-of-sight direction is displayed on a head-up display. Assuming that a next intersection at which to change lane according to a guidance route is the target intersection, a combination of the virtual point of view and virtual line-of-sight direction is gradually changed from a combination in which a scene is viewed from the point of view of the user in the forward direction of the vehicle to a combination for taking a bird's eye view of a geographic range that includes the current position of the vehicle and then to a combination for taking a bird's eye view of a geographic range that includes the target intersection from a point near the target intersection.

  • Patent number: 10319393
    Abstract: When an instruction to start voice input is received from the user, a gain controller acquires, from a gain table which defines a correspondence between vehicle speed ranges and gains, a gain corresponding to a vehicle speed range including the vehicle speed of a vehicle detected by a vehicle speed detector, and sets the acquired gain as the gain of an input amplifier that amplifies an input audio signal output by a microphone. As a gain corresponding to each vehicle speed range, the gain table records a gain of the input amplifier corresponding, in an experimentally determined frequency distribution of peak values in the vehicle speed range, to a maximum frequency in the range of magnitude of voice output as an input audio signal by the microphone and to be input to a speech recognition engine as voice having a magnitude within the input range of the speech recognition engine.
