Abstract
A vehicular head-up display that is provided in a vehicle and is configured to display a predetermined image to an occupant of the vehicle includes: a housing that has an opening upward; a transparent cover that covers the opening of the housing; a picture generation section; and a cleaner that is configured to clean an outer surface of the transparent cover. The picture generation section includes: a picture generation unit that is provided inside an accommodation portion formed with the housing and the transparent cover in order to emit light for generating the predetermined image; and a reflection unit that reflects light so that light emitted by the picture generation unit heads toward a windshield.
Claims18
A vehicular head-up display that is provided in a vehicle and is configured to display a predetermined image to an occupant of the vehicle comprising:
- a housing that has an opening upward;
- a transparent cover that covers the opening of the housing;
- a picture generation section comprising:
- a picture generation unit that is provided inside an accommodation portion formed with the housing and the transparent cover in order to emit light for generating the predetermined image;
- and
- a reflection unit that reflects light so that light emitted by the picture generation unit heads toward a windshield;
- and
- a cleaner that is configured to clean an outer surface of the transparent cover;
- wherein the cleaner is provided inside the housing and is configured to be actuated according to output of a dirt sensor configured to determine a degree of dirt on the transparent cover based on reflection of the light emitted from the reflection unit at the transparent cover.
A vehicular head-up display that is provided in a vehicle and is configured to display a predetermined image to an occupant of the vehicle comprising:
- a picture generation unit that is configured to emit light for generating the predetermined image;
- a reflection unit that reflects light emitted by the picture generation unit to a windshield and comprise at least a concave mirror;
- and
- a shade unit that is capable of blocking light from entering the picture generation unit, wherein
- the shade unit is movable between:
- a closed position in which an optical path between the picture generation unit and the concave mirror is blocked, and
- an open position in which the optical path between the picture generation unit and the concave mirror is not blocked.
A vehicular head-up display system that is provided in a vehicle and is configured to display a predetermined image to an occupant of the vehicle comprising:
- a detection unit that is configured to detect an object based on information acquired from an in-vehicle sensor to detect a position of the object;
- a determination unit that is configured to determine whether the object is in a blind spot of the driver;
- a shade unit that is capable of blocking light from entering a picture generation unit;
- and
- an image output unit that generates an image indicating the object to cause the image to be displayed on a display unit when a signal is acquired indicating that the determination unit determines the object is in the blind spot,
- wherein the image output unit generates an image by taking light generated by the picture generation unit and reflecting it off of a reflection unit onto the display unit,
- wherein the reflection unit comprises at least a concave mirror,
- wherein the shade unit is movable between:
- a closed position in which an optical path between the picture generation unit and the concave mirror is blocked, and
- an open position in which the optical path between the picture generation unit and the concave mirror is not blocked.
