Travel Control System with Scene-Based Priority Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing travel control systems for vehicles do not adequately consider the user's intention, leading to inappropriate control of vehicle travel.
Innovation Solution
A travel control device that determines the travel scene based on the vehicle's state and presents relevant information to the user, allowing the user to input responses to control the vehicle accordingly, prioritizing presentation information based on the situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated travel control is implemented without user confirmation, then productivity and response time are improved, but the control may not align with user intention reducing reliability
Solution Approach 1:
The system presents detection results and travel scene information to the user through a display unit, allowing the user to confirm or correct the system's interpretation of the travel situation. This feedback loop ensures that automated control actions align with user intention while maintaining rapid response capability.
Solution Approach 2:
The system performs preliminary detection and analysis of the travel scene, preparing control options in advance. By presenting pre-analyzed information to the user before execution, the system enables quick user confirmation while ensuring the control aligns with user intention.
2Loss of information
If multiple presentation information items are shown to the user, then completeness of information is improved, but user confusion increases and ease of operation deteriorates
Solution Approach 1:
The system segments presentation information by priority levels, displaying high-priority information prominently and low-priority information separately or optionally. This segmentation allows complete information to be provided while maintaining ease of operation by organizing content hierarchically.
Solution Approach 2:
Different regions or aspects of the display provide different levels of information detail. Critical travel scene elements are highlighted with higher visibility and prominence, while secondary information is presented with lower emphasis, allowing users to quickly grasp essential information without being overwhelmed.

AI summary
A travel control device is provided which comprises a detection unit (110) configured to detect a travel state of a subject vehicle, a determination unit (180) configured to determine a travel scene of the subject vehicle on the basis of the travel state of the subject vehicle, a storage unit (180) configured to store presentation information to be presented to a user in each travel scene, a presentation unit (180) configured to present the presentation information corresponding to the travel scene to the user, an input unit (160) for the user to input response information in response to the presentation information, and a control unit (180) configured to control travel of the subject vehicle on the basis of the response information. The storage unit (180) stores a priority level when presenting the presentation information, in association with the presentation information. The presentation unit (180) presents the presentation information of which the priority level is highest to the user when an actual travel scene of the subject vehicle falls under travel scenes corresponding to two or more items of the presentation information stored in the storage unit.
