Abstract

Claims (68)

1 . A method comprising:

determining whether a user in a vehicle is experiencing motion sickness based on at least a phasal difference between a first movement measurement of the vehicle and a second movement measurement of a head of the user using a radar sensor;

in response to determining whether the user is experiencing motion sickness, activating mitigation control;

determining whether a second user in the vehicle is experiencing motion sickness based on the first movement measurement and a third movement measurement of a head of the second user using a second radar;

determining which of the user or the second user is experiencing more severe motion sickness; and

generating a drop off schedule based on which of the user or the second user is experiencing more severe motion sickness.

2 . The method of claim 1 , wherein the first movement measurement and the second movement measurement are based on one or more of:

a movement measurement;

a velocity measurement; or

an acceleration measurement.

3 . The method of claim 1 , wherein the first movement measurement and the second movement measurement are triaxial.

4 . The method of claim 1 , wherein the radar sensor is multiple input, multiple output millimeter wave radar.

5 . The method of claim 1 , further comprising:

receiving a motion sickness sensitivity score from the user; and

wherein determining whether the user is experiencing motion sickness is further based on the motion sickness sensitivity score.

6 . The method of claim 1 , wherein the mitigation control includes at least one of:

adjusting a vehicle cabin temperature;

adjusting a vehicle seat recline angle;

opening a vehicle window;

adjusting a window tint;

activating a seat ventilation system; or

adjusting vehicle driving style.

7 . A system, comprising:

a processor; and

a memory storing machine-readable instructions that, when executed by the processor, cause the processor to:

determine whether a user in a vehicle is experiencing motion sickness based on at least a phasal difference between a first movement measurement of the vehicle and a second movement measurement of a head of the user using a radar sensor;

in response to determining whether the user is experiencing motion sickness, activate mitigation control;

determine whether a second user in the vehicle is experiencing motion sickness based on the first movement measurement and a third movement measurement of a head of the second user using a second radar;

determine which of the user or the second user is experiencing more severe motion sickness; and

generate a drop off schedule based on which of the user or the second user is experiencing more severe motion sickness.

8 . The system of claim 7 , wherein the first movement measurement and the second movement measurement are based on one or more of:

a movement measurement;

a velocity measurement; or

an acceleration measurement.

9 . The system of claim 7 , wherein the first movement measurement and the second movement measurement are triaxial.

10 . The system of claim 7 , wherein the radar sensor is multiple input, multiple output millimeter wave radar.

11 . The system of claim 7 , wherein the machine-readable instructions further include instructions that when executed by the processor cause the processor to:

receive a motion sickness sensitivity score from the user; and

determine whether the user is experiencing motion sickness further based on the motion sickness sensitivity score.

12 . The system of claim 7 , wherein the mitigation control includes at least one of:

adjusting a vehicle cabin temperature;

adjusting a vehicle seat recline angle;

opening a vehicle window;

adjusting a window tint;

activating a seat ventilation system; or

adjusting vehicle driving style.

13 . A non-transitory computer-readable medium including instructions that when executed by a processor cause the processor to:

determine whether a user in a vehicle is experiencing motion sickness based on at least a phasal difference between a first movement measurement of the vehicle and a second movement measurement of a head of the user using a radar sensor;

in response to determining whether the user is experiencing motion sickness, activate mitigation control;

determine whether a second user in the vehicle is experiencing motion sickness based on the first movement measurement and a third movement measurement of a head of the second user using a second radar;

determine which of the user or the second user is experiencing more severe motion sickness; and

generate a drop off schedule based on which of the user or the second user is experiencing more severe motion sickness.

14 . The non-transitory computer-readable medium of claim 13 , wherein the first movement measurement and the second movement measurement are based on one or more of:

a movement measurement;

a velocity measurement; or

an acceleration measurement.

15 . The non-transitory computer-readable medium of claim 13 , wherein the first movement measurement and the second movement measurement are triaxial.

16 . The non-transitory computer-readable medium of claim 13 , wherein the radar sensor is multiple input, multiple output millimeter wave radar.

17 . The non-transitory computer-readable medium of claim 13 , wherein the instructions further include instructions that when executed by the processor cause the processor to:

receive a motion sickness sensitivity score from the user; and

determine whether the user is experiencing motion sickness further based on the motion sickness sensitivity score.

18 . The non-transitory computer-readable medium of claim 13 , wherein the mitigation control includes at least one of:

adjusting a vehicle cabin temperature;

adjusting a vehicle seat recline angle;

opening a vehicle window;

adjusting a window tint;

activating a seat ventilation system; or

adjusting vehicle driving style.
