Motion Sickness Mitigation System And Method
Systems and methods are provided for mitigating motion sickness. When motion sickness is predicted, the motion sickness mitigation system alters vehicle performance, cabin conditions, and/or alerts the occupant to upcoming vehicle actions, to avoid or alleviate motion sickness. A controller includes a processor that receives an occupant profile and traffic information for an upcoming trip of the vehicle on a route. Using the occupant profile and the traffic information, the processor calculates whether the occupant will experience motion sickness when the vehicle travels on the route. A vehicle performance signal correlated to the calculation, is delivered by the processor to initiate motion sickness mitigation. The vehicle performance signal varies operation of a steering actuator, an acceleration actuator, and/or a brake actuator to implement the motion sickness mitigation.

- 1. A motion sickness mitigation system of a vehicle comprising:
a steering system of the vehicle including a steering actuator steering the vehicle through the steering system; a braking system including a brake actuator actuating the braking system; an accelerator system including an accelerator actuator actuating the accelerator system; and a controller including a processor configured to:
receive an occupant profile that includes a biometric condition of an occupant, preferences of the occupant and historical travel information of the occupant in the vehicle,
receive traffic information for an upcoming trip of the vehicle on a route,
calculate, using the occupant profile and the traffic information, whether the occupant is likely to experience motion sickness when the vehicle travels on the route, and
deliver a vehicle performance signal correlated to the calculation, to initiate motion sickness mitigation,
wherein the vehicle performance signal varies operation of the steering actuator, the accelerator actuator or the brake actuator to implement the motion sickness mitigation.
- 8. A method of motion sickness mitigation in a vehicle comprising:
receiving, by a processor of a controller, a data input signal that represents an occupant profile that includes a biometric condition of an occupant, preferences of the occupant, and historical travel information of the occupant in the vehicle; receiving, by the processor, an off-board input signal representing traffic status for an upcoming trip of the vehicle on a route; calculating, by the processor, whether the occupant is likely to experience motion sickness when the vehicle travels on the route, using the data input signal and the off-board input signal; and delivering a vehicle performance signal to initiate motion sickness mitigation, wherein the vehicle performance signal varies operation of a steering actuator of the vehicle, an accelerator actuator of the vehicle, or a brake actuator of the vehicle when the vehicle operates on the route, to implement the motion sickness mitigation.
- 20. A motion sickness mitigation system of a vehicle comprising:
an acceleration sensor sensing acceleration of the vehicle and generating an acceleration signal representative of the sensed acceleration; a camera configured to observe an occupant of the vehicle and providing a visual signal representative of the occupant; a controller receiving the acceleration signal and the visual signal and including a processor, the processor configured to:
discern, from the visual signal a direction the occupant is looking;
select an interface modality based on the direction; and
communicate with the occupant through the interface modality; and
an actuator device responsive to the processor, wherein the actuator device controls performance of a vehicle system; wherein the processor is configured to calculate whether the occupant is likely to experience motion sickness based on the acceleration signal and the visual signal; wherein the processor controls the actuator device in a variable manner depending on whether the calculation indicates the occupant is likely to experience motion sickness.
