Abstract

Claims (60)

1 . A hologram projection system for a vehicle, the hologram projection system comprising:

a controller;

a housing including a plurality of through-holes formed in an upper surface of the housing;

a casing storing water and connected to the housing;

a sprayer mounted in the housing and fluidly connected to the casing, and including a plurality of nozzles protruding through the through-holes in the upper surface of the housing, wherein the sprayer is electrically connected to the controller, configured to spray water in the casing as water mist by performing a spray operation under a control of the controller, and configured to spray the water mist toward a location above the housing through the nozzles; and

a hologram projection device provided in the housing, electrically connected to the controller, and including a light-emitting device mounted on the upper surface of the housing,

wherein the hologram projection device is configured to generate different beams under control of the controller and to form different patterns by projecting the different beams to the water mist formed above the housing by the light-emitting device.

2 . The hologram projection system of claim 1 , wherein the plurality of nozzles of the sprayer is provided in a circumferential direction around the light-emitting device.

3 . The hologram projection system of claim 1 , wherein the nozzles are each directed upward in a vertical direction or inclined at a predetermined angle with respect to the vertical direction control of the controller.

4 . The hologram projection system of claim 3 , wherein the nozzles are each inclined at the predetermined angle toward a front side of the vehicle with respect to the vertical direction, and a range of the predetermined angle is 0 to 10 degrees.

5 . The hologram projection system of claim 1 , wherein the controller is configured to incline the nozzles by the predetermined angle in response that a vehicle window is opened.

6 . The hologram projection system of claim 1 ,

wherein the controller is further configured to:

obtain operating states of the hologram projection device and the sprayer;

obtain a hologram projection theme selected by a user in response to operations of the hologram projection device and the sprayer; and

transmit a first instruction to the hologram projection device in accordance with the hologram projection theme selected by the user, and

wherein the first instruction is provided to control the hologram projection device to project the different beams to the water mist and form a pattern corresponding to the selected hologram projection theme in the water mist among the different patterns.

7 . The hologram projection system of claim 6 , wherein the hologram projection theme includes at least one of a music rhythm, a moonlight dance, a natural image, and a vehicle speed.

8 . The hologram projection system of claim 6 ,

wherein the controller is further configured to:

obtain a ratio between a height of an opening defined above a glass and a height of a vehicle window; and

transmit a second instruction to an actuator of the glass, in response to the ratio exceeding a predetermined value, and

wherein the second instruction is provided to control and raise the glass of the vehicle window until the ratio becomes equal to the predetermined value and to control the nozzles of the sprayer so that at least one nozzle of the nozzles is inclined toward a front side of the vehicle.

9 . The hologram projection system of claim 6 ,

wherein the controller is further configured to:

obtain an operating mode of an air conditioner of the vehicle; and

transmit a third instruction to the air conditioner in response to the air conditioner being in a face direction blowing mode, and

wherein the third instruction is provided to the air conditioner to control the air conditioner to switch a mode to a foot direction blowing mode of the air conditioner.

10 . The hologram projection system of claim 6 ,

wherein the controller is further configured to:

obtain a vehicle speed, a state of a parking brake, and a state of a door lock in response to a door opening warning mode being selected; and

transmit a fourth instruction to the hologram projection device in response to the vehicle speed being 0, the parking brake being in a parking state, and the door lock being in a released state, and

wherein the fourth instruction is provided to control the hologram projection device to project warning beams to the water mist.

11 . A vehicle including the hologram projection system of claim 1 .

12 . A method of controlling a hologram projection system for a vehicle, the hologram projection system including a controller, a housing including a plurality of through-holes formed in an upper surface of the housing, a casing storing water and connected to the housing, a sprayer mounted in the housing and fluidly connected to the casing and including a plurality of nozzles protruding through the through-holes in the upper surface of the housing, and a hologram projection device provided in the housing, electrically connected to the controller, and including a light-emitting device mounted on the upper surface of the housing, the method comprising:

controlling, by the controller, the sprayer and the light-emitting device of the hologram projection device to generate different beams and to form different patterns by projecting the different beams to water mist formed above the housing by the sprayer spraying water as the water mist.

13 . The method of claim 12 , wherein the controller is further configured to control a position of the nozzles to a vertical direction or at a predetermined angle with respect to the vertical direction.

14 . The method of claim 12 , wherein the controller is further configured to incline the nozzles by the predetermined angle, in response that a vehicle window is opened.

15 . The method of claim 12 ,

wherein the controller is further configured to:

obtain operating states of the hologram projection device and the sprayer;

obtain a hologram projection theme selected by a user in response to operations of the hologram projection device and the sprayer; and

transmit a first instruction to the hologram projection device in accordance with the hologram projection theme selected by the user, and

wherein the first instruction is provided to control the hologram projection device to project the different beams to the water mist and form a pattern corresponding to the selected hologram projection theme in the water mist among the different patterns.

16 . The method of claim 15 , wherein the hologram projection theme includes at least one of a music rhythm, a moonlight dance, a natural image, and a vehicle speed.

17 . The method of claim 15 ,

wherein the controller is further configured to:

obtain a ratio between a height of an opening defined above a glass and a height of a vehicle window; and

transmit a second instruction to an actuator of the glass in response to the ratio exceeding a predetermined value, and

wherein the second instruction is provided to control and raise the glass of the vehicle window until the ratio becomes equal to the predetermined value and to control the nozzles of the sprayer so that at least one nozzle of the nozzles is inclined toward a front side of the vehicle.

18 . The method of claim 15 ,

wherein the controller is further configured to:

obtain an operating mode of an air conditioner of the vehicle; and

transmit a third instruction to the air conditioner in response to the air conditioner being in a face direction blowing mode, and

wherein the third instruction is provided to the air conditioner to control the air conditioner to switch a mode to a foot direction blowing mode of the air conditioner.

19 . The method of claim 15 ,

wherein the controller is further configured to:

obtain a vehicle speed, a state of a parking brake, and a state of a door lock in response to a door opening warning mode being selected; and

transmit a fourth instruction to the hologram projection device in response to the vehicle speed being 0, the parking brake being in a parking state, and the door lock being in a released state, and
