Vehicle efficacious constituents supply apparatus
View Patent ↗A vehicle efficacious constituents supply apparatus 10 includes a main unit 13 including an air gun and a subunit 15 including an air gun. A curling ring V 1 of air containing aromatic constituents is projected from the main unit 13 towards an efficacious area A, while a curling ring V 2 of air is projected from the subunit 15 towards the efficacious area A. A control unit for controlling projection timings of curling rings V 1 , V 2 includes an alarming mode in which a projection interval at which curling rings v 1 are projected is set shorter than a projection interval at which curling rings V 2 are projected, and by executing this alarming mode, curling rings V 2 can be applied to an occupant without causing the curling rings V 2 so projected to disappear in the efficacious area A.
1. A vehicle efficacious constituents supply apparatus, comprising:
a first projecting section for projecting a first curl of air towards a first predetermined position;
a second projecting section for projecting a second curl of air towards a second predetermined position;
a constituents supply section for supplying efficacious constituents to at least either of the first curl of air and the second curl of air; and
a projection control section for controlling projection timings of the first curl of air and the second curl of air,
wherein the projection control section is configured to control the first projecting section second protecting section in projection modes including an efficacious mode in which efficacious constituents are diffused by causing the first curl of air and the second curl of air to collide with each other and an alarm mode for causing at least either of the first curl of air and the second curl of air to collide against an occupant without causing the curls of air to collide with each other.
2. The vehicle efficacious constituents supply apparatus as set forth in claim 1 , further comprising an awakening detection section for detecting a degree of awakening of the occupant,
wherein the projection control section executes the alarm mode based on the degree of awakening of the occupant.
3. The vehicle efficacious constituents supply apparatus as set forth in claim 1 , wherein the first predetermined position and the second predetermined position are identical.
4. The vehicle efficacious constituents supply apparatus as set forth in claim 1 , wherein the efficacious constituents comprise at least one of aromatic constituents, microscopic mists, ozone and oxygen.
5. The vehicle efficacious constituents supply apparatus as set forth in claim 1 , wherein the projection control section sets a projection timing of the first curl of air equal to a projection timing of the second curl of air in the efficacious mode and sets the projection timing of the first curl of air to be shorter than the projection timing of the second curl of air in the alarm mode.
6. The vehicle efficacious constituents supply apparatus as set forth in claim 1 , wherein the first curl of air and the second curl of air collide with each other in an efficacious area which is set in front of a nose of the occupant.
7. A method of providing efficacious constituents to an occupant in a vehicle, the method comprising:
determining a degree of awakening of the occupant;
projecting a first curl of air and a second curl of air to collide with each other when said determining determines that the degree of awakening of the occupant is not reduced; and
projecting the first curl of air and the second curl of air not to collide with each other and to collide against the occupant when said determining determines that the degree of awakening of the occupant is reduced.
8. The method according to claim 7 , further comprising providing aromatic constituents in said first curl of air and said second curt of air.
9. The method according to claim 8 , wherein the projecting of the first curl of air and the second curl of air are supplied with one of a mint or citrus fruit-based aromatic constituents when said determining determines that the degree of awakening of the occupant is reduced.
10. The method according to claim 7 , wherein when said determining determines that the degree of awakening of the occupant is reduced, a projection timing of the first curl of air is set shorter than a projection timing of the second curl of air.
11. The method according to claim 7 , wherein when said determining determines that the degree of awakening of the occupant is not reduced, a projection timing of the first curl of air is set equal to a projection timing of the second curl of air.
12. The method according to claim 7 , wherein the projecting of the first curl of air and the second curl of air to collide with each other in an efficacious area is set in front of a nose of the occupant.
13. The method according to claim 7 , wherein the determining of the degree of awakening of the occupant comprises measuring at least one of a steering wheel angle, a yaw rate sensor output, a vehicle speed sensor, and a stereoscopic camera image from a front of a vehicle.
