Apparatus and method for controlling vehicle seat
Disclosed are an apparatus and a method for controlling a vehicle seat so as to control a seat back and a neck pillow based on a sound. The apparatus includes the vehicle seat installed in a vehicle and including a seat back and a neck pillow, a detector for detecting vehicle information and seat information, and a processor connected to the vehicle seat and the detector, wherein the processor determines a vehicle state and a seat sitting posture based on the vehicle information and the seat information, analyzes a sound being reproduced in the vehicle, determines a haptic pattern and a haptic pressure based on the vehicle state and the seat sitting posture, and the analysis of the sound, and controls the seat back and the neck pillow based on the determined haptic pattern and haptic pressure to provide a haptic effect.
1. An apparatus for controlling a vehicle seat, the apparatus comprising:
a vehicle seat installed in a vehicle and comprising a seat back and a neck pillow;
a detector for detecting vehicle information and seat information; and
a processor connected to the vehicle seat and the detector,
wherein the processor is configured to:
determine a vehicle state and a seat sitting posture based on the vehicle information and the seat information;
analyze a sound being reproduced in the vehicle;
determine a haptic pattern and a haptic pressure based on the vehicle state, the seat sitting posture, and an analysis of the sound; and
control the seat back and the neck pillow, based on the determined haptic pattern and haptic pressure, to provide a haptic effect; and
wherein the processor is further configured to:
select a climax of the sound;
select the haptic pressure based on the sound, and
determine a haptic timing based on the selected climax and haptic pressure.
2. The apparatus of claim 1 , wherein the seat back comprises a hugging device installed in the seat back, wherein the hugging device comprises:
a support for supporting an upper body of a user sitting on the vehicle seat; and
a movable portion pivotally coupled to the support via a hinge portion.
3. The apparatus of claim 2 , wherein the support and the movable portion are each made of a laminated sheet.
4. The apparatus of claim 1 , wherein the neck pillow comprises at least one of an air tube, a vibrator, a soft actuator or a heating wire.
5. The apparatus of claim 1 , wherein the processor is further configured to select the haptic pattern based on the vehicle state and the seat sitting posture.
6. The apparatus of claim 1 , wherein the processor is further configured to determine the haptic pattern and the haptic pressure via frequency and amplitude analysis of the sound.
7. The apparatus of claim 1 , wherein the processor is further configured to provide the haptic effect via alternate vibrations of the seat back and the neck pillow.
8. The apparatus of claim 1 , wherein the processor is further configured to drive a hugging device in the seat back to activate a back hugging function.
9. The apparatus of claim 1 , wherein the processor is further configured to:
determine a driver state based on driver information detected by the detector; and
determine the haptic pattern and the haptic pressure based on the determined driver state, the vehicle state, and the seat sitting posture.
10. A vehicle comprising an apparatus of claim 1 .
11. A method for controlling a vehicle seat, the method comprising:
detecting a vehicle state and a seat sitting posture based on vehicle information and seat information detected by a detector;
analyzing a sound being reproduced in a vehicle;
determining a haptic profile and a haptic pressure based on the vehicle state, the seat sitting posture, and an analysis of the sound; and
controlling a seat back and a neck pillow based on the haptic profile and the haptic pressure to provide a haptic effect;
wherein the determining of the haptic profile and the haptic pressure comprises:
selecting a climax of the sound;
selecting the haptic pressure based on the sound; and
determining a haptic timing based on the selected climax and haptic pressure.
12. The method of claim 11 , wherein the determining of the haptic profile and the haptic pressure comprises selecting the haptic profile based on the vehicle state and the seat sitting posture.
13. The method of claim 11 , wherein the determining of the haptic profile and the haptic pressure further comprises determining the haptic profile and the haptic pressure via frequency and amplitude analysis of the sound.
14. The method of claim 11 , wherein the providing of the haptic effect comprises providing the haptic effect via alternate vibrations of the seat back and the neck pillow.
15. The method of claim 11 , wherein the providing of the haptic effect comprises controlling an operation of a hugging device disposed in the seat back so as to wrap an upper body of a user sitting on the vehicle seat.
16. The method of claim 11 , wherein the providing of the haptic effect comprises controlling at least one of an air tube, a massager, and a heating wire of the neck pillow to provide the haptic effect.
