Abstract

A Virtual Reality (VR)-based seat control apparatus for a vehicle includes: an input unit for receiving an image mode operation command from a user; and a control unit for playing a prepared timetable according to the image mode operation command, performing interlocking with a seat module of a vehicle and VR equipment, and controlling an operation module of the seat module according to the timetable.

First claim

What is claimed is:

1 . A Virtual Reality (VR)-based seat control apparatus for a vehicle, comprising:
at least one processor configured to: receive, from a user, a command to operate an image mode; prepare a timetable of a VR image for the image mode, the timetable including a timeline of the VR image and a type of operation of a seat module of the vehicle to be synchronized with the VR image; run the timetable according to the command; perform synchronizing with the seat module of the vehicle and a VR equipment; control the seat module according to the timetable; determine a driving mode of the vehicle, the driving mode including a stopped mode or a travelling mode, according to the command; when the driving mode of the vehicle is determined to be the travelling mode, receive vehicle information of the vehicle, the vehicle information including a rotational speed of the vehicle and whether a road on which the vehicle travels includes an unpaved road or a bump, and predict a vehicle state to be a normal state or a dangerous state by using the vehicle information, the dangerous state being predicted when the rotational speed of the vehicle is equal to or greater than a reference rotational speed and when the road includes the unpaved road or the bump; and apply a result of prediction of the vehicle state to the timetable and stop operation of the seat module at a time corresponding to the dangerous state of the vehicle in the timetable.

2 . The VR-based seat control apparatus of claim 1 ,
wherein the at least one processor is further configured to: output an operation notification sound to indicate an initiation of the image mode according to the command.

3 . The VR-based seat control apparatus of claim 1 , wherein when the vehicle is not in the travelling mode, the at least one processor is configured to determine whether to move a seat of the seat module to an initial position.

4 . The VR-based seat control apparatus of claim 3 ,
wherein the at least one processor is configured to determine to move the seat of the seat module to the initial position when the at least one processor receives, from the VR equipment, information that a VR image has not been played or has finished playing, and wherein the at least one processor is configured to determine to maintain the seat of the seat module at a current position when the at least one processor receives, from the VR equipment, information of stopping playback of the VR image.

5 . The VR-based seat control apparatus of claim 4 , wherein when the at least one processor determines to move the seat of the seat module to the initial position, the at least one processor is configured to control the seat module to move the seat of the seat module to the initial position.

6 . The VR-based seat control apparatus of claim 4 , wherein when the at least one processor determines to maintain the seat of the seat module in the current position, the at least one processor is configured to check a synchronizing status with the seat module after waiting for a predetermined time, calculate a start time of the synchronizing, and run the timetable according to the start time of the synchronizing.

7 . A Virtual Reality (VR)-based seat control method for a vehicle, comprising:
receiving, by a seat control device having a display, a command to operate an image mode from a user; preparing a timetable of a VR image for the image mode, the timetable including a timeline of the VR image and a type of operation of a seat module of the vehicle to be synchronized with the VR image; running, by a controller of the seat control device, the timetable according to the command; and synchronizing, by the controller, with the seat module of the vehicle and a VR equipment, and controlling the seat module according to the timetable, determining, by the seat control device, a driving mode of the vehicle, the driving mode including a stopped mode or a travelling mode, according to the command, receiving, when the vehicle is in the travelling mode, by the controller, vehicle information of the vehicle, the vehicle information including a rotational speed of the vehicle and whether a road on which the vehicle travels includes an unpaved road or a bump; and predicting, by the controller, a vehicle state including a normal state and a dangerous state based on the vehicle information, the dangerous state being predicted when the rotational speed of the vehicle is equal to or greater than a reference rotational speed and when the road includes the unpaved road or the bump; and applying, by the controller, a result of prediction of the vehicle state to the timetable, and when the dangerous state is predicted, stopping operation of the seat module at a time corresponding to the dangerous state of the vehicle in the timetable.

8 . The VR-based seat control method of claim 7 , further comprising:
outputting, by a speaker of the seat control device, an operation notification sound to indicate an initiation of the image mode according to the command.

9 . The VR-based seat control method of claim 8 , further comprising:
determining, by the seat control device, whether to move a seat of the seat module to an initial position or maintain the seat of the seat module at a current position when the driving mode of the vehicle is not a traveling mode, after the driving mode of the vehicle is determined.

10 . The VR-based seat control method of claim 9 , wherein the determining of whether to move a seat of the seat module to an initial position or maintain the seat of the seat module at a current position includes:
determining, by the seat control device, to move the seat of the seat module to the initial position when the seat control device receives, from the VR equipment, information that a VR image has not been played or has finished playing; and determining, by the seat control device, to maintain the seat of the seat module at the current position when the seat control device receives, from the VR equipment, information of stopping playback of the VR image.

11 . The VR-based seat control method of claim 10 , further comprising:
moving, by the controller, the seat of the seat module to the initial position by controlling the seat module when the controller determines to move the seat of the seat module to the initial position, after the determining of whether to move the seat of the seat module to the initial position or maintain the seat of the seat module at the current position.

12 . The VR-based seat control method of claim 10 , further comprising:
after the determining of whether to move the seat of the seat module to the initial position or maintain the seat of the seat module at the current position, waiting for a predetermined time when the controller determines to maintain the seat of the seat module in the current position; and checking, by the controller, a state of the synchronizing with the seat module after the waiting for the predetermined time, and calculating a start time of the synchronizing.

13 . The VR-based seat control method of claim 12 , further comprising:
after the synchronizing, stopping, by the controller, the synchronizing with the seat module and the VR equipment when the running of the timetable is completed; and outputting, by the speaker, a termination notification sound to indicate stopping of the synchronizing when the synchronizing with the seat module is stopped.
