Autonomous Driving Interface for Passenger Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving systems cause cognitive dissonance in passengers, leading to physical abnormalities like motion sickness due to the inability to predict the vehicle's trajectory and behavior, hindering the growth of the autonomous vehicle market.
Innovation Solution
An apparatus and method that includes a travel detection unit, an autonomous-driving control unit, and an interface control unit to detect travel environments and conditions, predict passenger physical abnormalities, and generate vehicle operation contents to alleviate these issues by providing operation information to passengers through display or acoustic means, tailored to their gaze direction and state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous vehicle performs vehicle operation automatically, then the driver's workload is decreased and non-driving actions are enabled, but the driver experiences cognitive dissonance and motion sickness due to inability to predict vehicle behavior
Solution Approach 1:
The patent introduces an information provision system that acts as an intermediary between the autonomous driving system and the driver. This system provides real-time information about vehicle operations (steering, acceleration, braking) to the driver through displays or audio outputs, allowing the driver to understand and predict vehicle behavior without needing to actively control it, thereby reducing cognitive dissonance and motion sickness while maintaining low workload
Solution Approach 2:
The system implements feedback by continuously providing information about the autonomous vehicle's intended actions and actual operations to the driver. This feedback loop includes notifying the driver before operations occur and providing real-time status updates, enabling the driver to mentally synchronize with vehicle behavior and reduce cognitive dissonance
2Ease of operation
If the driver performs non-driving actions such as reading or video watching, then convenience is increased, but cognitive dissonance increases and motion sickness becomes more likely
Solution Approach 1:
The system provides advance notification to the driver about upcoming vehicle operations before they occur. By notifying the driver in advance of steering, acceleration, or braking actions, the driver can mentally prepare and predict vehicle behavior even while engaged in non-driving actions, reducing cognitive dissonance without requiring constant visual attention to the road

AI summary
An apparatus for controlling autonomous driving may include: a travel detection unit configured to detect travel environment and travel conditions of a host vehicle that is in an autonomous driving state; an autonomous-driving control unit configured to control the autonomous driving of the host vehicle based on the travel environment and the travel conditions detected by the travel detection unit, and predict physical abnormalities occurring in a passenger of the host vehicle due to the autonomous driving of the host vehicle; and an interface control unit configured to generate vehicle operation contents of the host vehicle for alleviating the predicted physical abnormalities, when the passenger's physical abnormalities are predicted by the autonomous-driving control unit, and then to provide the generated vehicle operation contents for the passenger.
