Display device for vehicle
A display device includes a projection device RP that projects a notification pattern on a region in the vicinity of a vehicle CAR, an imaging device RC that images the region in the vicinity of the vehicle, and an object detection device OS capable of detecting an object (third party) present in a region which cannot be imaged by the imaging device RC. When the object detection device OS detects the object, the projection device RP projects the notification pattern in a form different from the notification in a normal state, so that the third party can visually recognize the notification pattern. The imaging device RC images a region including a region on which the notification pattern is projected, and displays, on a monitor MO visually checkable by the occupant, a captured image of the notification pattern projected in the form different from the notification pattern in the normal state.
1 . A vehicle display device comprising:
a projection device that projects a notification pattern on a region in vicinity of a vehicle;
an imaging device that images an imaging region in the vicinity of the vehicle; and
an object detection device capable of detecting an object present in a detection region including at least a part of the imaging region and a region which cannot be imaged by the imaging device,
wherein when the object detection device detects the object in a region within the detection region but outside of the imaging region, the projection device projects the notification pattern in a form different from the notification pattern in a normal state.
2 . The vehicle display device according to claim 1 , wherein
the imaging device is capable of imaging a region including at least a region on which the notification pattern is projected, and
a captured image is displayed on a monitor visually checkable by an occupant of the vehicle.
3 . The vehicle display device according to claim 1 , wherein
the notification pattern includes a first notification pattern and a second notification pattern that correspond to different movement modes of the vehicle, and
at least one of a pattern shape or color is different between the first notification pattern and the second notification pattern.
4 . The vehicle display device according to claim 3 , wherein at least one of the first notification pattern or the second notification pattern is projected in a blinking state when the object detection device detects the object.
5 . The vehicle display device according to claim 3 , wherein a projection position or a projection direction of at least one of the first notification pattern and the second notification pattern is changed when the object detection device detects the object.
6 . The vehicle display device according to claim 3 , wherein
the projection device includes a first projection device that projects the first notification pattern, and
a second projection device that projects the second notification pattern.
7 . The vehicle display device according to claim 6 , wherein the first projection device and the second projection device are installed in a lamp housing of the vehicle.
8 . The vehicle display device according to claim 6 , wherein the first projection device and the second projection device are installed in one casing.
9 . The vehicle display device according to claim 6 , wherein
the first projection device and the second projection device include
a first light source unit and a second light source unit, and
a projection lens that projects the first notification pattern and the second notification pattern by the light source units.
10 . The vehicle display device according to claim 3 , wherein
the first notification pattern is a back notification pattern projected when the vehicle moves backward, and
the second notification pattern is a rear turn notification pattern indicating a traveling direction of the vehicle.
11 . A vehicle display device comprising:
a projection device configured to project a notification pattern on a region in vicinity of a vehicle;
an imaging device configured to image an imaging region in the vicinity of the vehicle, the imaging region including at least the region on which the notification pattern is projected;
an object detection device configured to detect an object present in a detection region including at least a part of the imaging region and a region which cannot be imaged by the imaging device and output a detection signal;
a monitor configured to display an image captured by the imaging device visually checkable by an occupant of the vehicle, the image including the notification pattern projected by the projection device; and
a display control unit that controls projection of the notification pattern by the projection device based on the detection signal,
wherein the display control unit is configured to determine whether the object detection device detects the object in a region within the detection region but outside of the imaging region, and control the projection device to project the notification pattern in a form different from the notification pattern in a normal state based on the detection signal indicating that the object detection device detects the object in the region within the detection region but outside of the imaging region.
