Autonomous Driving Requirement Presentation for Smooth Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack detailed information presentation when transitioning from manual driving to autonomous driving, failing to distinguish between driver-solvable and environment-solvable requirements for initiating autonomous driving, which hinders smooth transitions.
Innovation Solution
A vehicle presentation control device that specifies driver requirements and environmental requirements for autonomous driving initiation, presenting driver-specific information before starting autonomous driving to address these requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If generic requirement presentation is used for autonomous driving initiation, then the system complexity is reduced, but the driver preparation and transition smoothness deteriorate
Solution Approach 1:
The patent segments the autonomous driving start requirements into two distinct categories: driver requirements (e.g., driver attention, readiness) and environmental requirements (e.g., road conditions, weather). This segmentation enables targeted presentation of information relevant to each category, improving driver preparation without requiring the system to manage all possible requirements uniformly, thus balancing ease of operation with acceptable system complexity.
Solution Approach 2:
The system performs preliminary action by presenting driver requirements before the autonomous driving initiation process is complete. The processor identifies and presents information about driver requirements in advance, allowing the driver to prepare appropriately (e.g., ensure proper seating position, remove distractions) before autonomous driving begins, thereby improving ease of operation while maintaining manageable system complexity through phased information delivery.
2Ease of operation
If detailed requirement presentation is provided before autonomous driving, then the driver preparation improves, but the information overload and driver attention burden increases
Solution Approach 1:
The patent applies local quality by tailoring the information presentation to the specific requirement category. Driver requirements are presented with emphasis on actions the driver can control (e.g., 'ensure you are properly seated'), while environmental requirements are presented as informational context (e.g., 'road conditions are suitable'). This differentiated presentation approach improves driver preparation by focusing on actionable items while avoiding information overload through selective detail provision.
Solution Approach 2:
The system uses partial action by selectively presenting only the necessary subset of requirements rather than all possible requirements. The processor identifies which requirements are currently relevant and presents those specifically, avoiding the presentation of extraneous information. This partial presentation approach ensures adequate driver preparation without creating information overload, as the driver receives precisely the information needed for the current situation.
3Measurement precision
If driver requirements are distinguished from environmental requirements, then the targeted information presentation improves, but the requirement analysis complexity increases
Solution Approach 1:
The patent implements segmentation by establishing clear criteria for distinguishing driver requirements from environmental requirements. Driver requirements are identified as those related to driver state and actions (e.g., attention level, seating position), while environmental requirements are identified as those related to external conditions (e.g., road geometry, weather). This segmentation enables precise requirement classification without excessive analysis complexity, as the classification rules are based on straightforward categorical distinctions rather than complex multi-factor analysis.

AI summary
A vehicle presentation control device, which is usable in a vehicle capable of performing autonomous driving, includes a processor. The processor distinguishably specifies, as an autonomous driving start requirement to be satisfied for a start of autonomous driving without monitoring obligation, at least a driver requirement, which is a requirement highly likely to be solved by a driver, or an environmental requirement, which is a requirement less likely to be solved by the driver. The processor starts, as requirement presentation that presents information about requirement necessary for the start of autonomous driving, driver requirement presentation, which indicates that the driver requirement is necessary for the start of autonomous driving, before the start of autonomous driving, in response to the specified autonomous driving start requirement being the driver requirement.
