AI Technical Summary

Technical Problem

Passengers are prone to motion sickness and decreased productivity when riding in autonomous vehicles. Existing technologies cannot effectively predict and regulate passenger conditions, resulting in a decline in passenger comfort and productivity.

Method used

The PREACT system uses machine learning to predict passenger status and generate preemptive commands. Through subsystems such as active seating, active restraint, active passenger stimulation, and active productivity interface, it adjusts passenger status in real time to reduce motion sickness and improve productivity.

Benefits of technology

By predicting passenger conditions and implementing proactive controls, motion sickness can be reduced, improving passenger comfort and productivity in the vehicle.

Abstract

The present disclosure proposes a passenger state modulation system for a passenger vehicle. The passenger state modulation system is used to predict an event (e.g., car sickness) affecting the passenger state before it occurs and implement preemptive intervention on vehicle active subsystems using the prediction.
