Abstract

An apparatus for controlling a vehicle includes at least one sensor to obtain status data of a user of the vehicle and data related to a motion of the user, and a processor to generate at least one motion sickness model, based on the status data of the passenger and the data related to the motion of the passenger, which are previously obtained, select a motion sickness model corresponding to the status data of the user, from among the at least one motion sickness model, and predict a motion sickness index of the user, by inputting the data related to the motion of the user into the selected motion sickness model.

First claim

What is claimed is:

1 . An apparatus for controlling a vehicle, the apparatus comprising:
at least one sensor configured to obtain status data of a user of the vehicle and data related to a motion of the user; and a processor configured to generate at least one motion sickness model, based on the status data of the passenger and the data related to the motion of the passenger, which are previously obtained, select a motion sickness model corresponding to the status data of the user, from among the at least one motion sickness model, and predict a motion sickness index of the user, by inputting the data related to the motion of the user into the selected motion sickness model.

2 . The apparatus of claim 1 , wherein the sensor obtains the status data of the passenger and the data related to the motion of the passenger.

3 . The apparatus of claim 1 , wherein the status data includes:
a seating position and a gaze direction.

4 . The apparatus of claim 1 , wherein the processor is configured to:
generate the at least one motion sickness model depending on the seating position of the passenger and the gaze direction of the passenger.

5 . The apparatus of claim 1 , wherein the processor is configured to:
generate the motion sickness model to pre-process the data related to the motion of the passenger, input the pre-processed result into a conflict model, transform a conflict vector, which is output from the conflict model, into a sickness severity, and calculate a motion sickness index of the passenger, based on the sickness severity.

6 . The apparatus of claim 5 , wherein the processor is configured to:
transform the conflict vector, which is output from the conflict model, into the motion sickness severity through a hill function.

7 . The apparatus of claim 5 , wherein the processor is configured to:
calculate the motion sickness index of the passenger using a cumulation function based on the motion sickness severity.

8 . The apparatus of claim 7 , wherein the processor is configured to:
allow an input of a misery scale, which is sensed by the passenger, corresponding to a motion sickness extent to obtain the misery scale; and set a parameter included in a time cumulation function based on the misery scale input by the passenger.

9 . The apparatus of claim 1 , wherein the processor is configured to:
control an operation of the vehicle, based on the predicted motion sickness index.

10 . A vehicle comprising the apparatus of claim 1 .

11 . A method for controlling a vehicle, the method comprising:
obtaining status data of a user of the vehicle and data related to a motion of the user by at least one sensor; generating at least one motion sickness model, based on the status data of the passenger and the data related to the motion of the passenger, which are previously obtained; selecting a motion sickness model corresponding to the status data of the user, from among the at least one motion sickness model; and predicting a motion sickness index of the user, by inputting the data related to the motion of the p user into the selected motion sickness model.

12 . The method of claim 11 , further comprising:
obtaining the status data of the passenger and the data related to the motion of the passenger by the at least one sensor.

13 . The method of claim 11 , wherein the status data may include a seating position and a gaze direction.

14 . The method of claim 11 , further comprising:
generating the at least one motion sickness model depending on the seating position of the passenger and the gaze direction of the passenger.

15 . The method of claim 11 , further comprising:
generating the motion sickness model to pre-process the data related to the motion of the passenger, input the pre-processed result into a conflict model, transform a conflict vector, which is output from the conflict model, into a sickness severity, and calculate a motion sickness index of the passenger, based on the sickness severity.

16 . The method of claim 15 , further comprising:
transforming the conflict vector, which is output from the conflict model, into the motion sickness severity through a hill function.

17 . The method of claim 15 , further comprising:
calculating the motion sickness index of the passenger using a cumulation function based on the motion sickness severity.

18 . The method of claim 17 , further comprising:
allowing an input of a misery scale, which is sensed by the passenger, corresponding to a motion sickness extent to obtain the misery scale.

19 . The method of claim 18 , further comprising:
setting a parameter included in a time cumulation function based on the misery scale input by the passenger.

20 . The method of claim 11 , further comprising:
controlling an operation of the vehicle, based on the predicted motion sickness index.
