Autonomous Driving State Presentation for Hands-Off Permission Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques fail to provide highly convenient information to drivers during transitions between different states of autonomous driving, such as from a prohibition state to a permission state, especially when transitioning from a hands-off state to a specific action permission state, where the driver may not immediately recognize the change.
Innovation Solution
A presentation control device and program that determine and present specific action permission states, hand-release permission states, and prohibition states, ensuring that transition allowable and execution information are presented in a manner that the driver can recognize the change effectively, particularly by presenting hand-release transition information simultaneously when transitioning from a hands-off permission state to a specific action permission state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If transition information is presented sequentially (allowable information before execution information) from both prohibition state to specific action permission state, then the driver has time to process the information, but the transition recognition is delayed
Solution Approach 1:
The patent dynamically adjusts the information presentation strategy based on the transition type. For transitions from both prohibition state, sequential presentation is used to ensure driver awareness. For transitions from hand release permission state, simultaneous presentation is used to provide immediate feedback. This dynamic adaptation resolves the contradiction between information completeness and response speed.
Solution Approach 2:
The patent changes the timing parameter of information presentation based on the current driving state. When transitioning from hand release permission state to specific action permission state, both allowable and execution information are presented simultaneously (time parameter changed). This parameter adjustment ensures the driver immediately recognizes the state change without delay.
2Speed
If transition information is presented simultaneously from hand release permission state to specific action permission state, then the driver immediately recognizes the change, but information overload may occur
Solution Approach 1:
The patent applies different information presentation strategies to different transition scenarios. For hand release permission state transitions, simultaneous presentation of allowable and execution information is used. For both prohibition state transitions, sequential presentation is used. This localized quality adjustment optimizes information delivery for each specific context without causing overload.
3Loss of information
If the system provides detailed transition information, then the driver understands the state change, but the information presentation becomes more complex
Solution Approach 1:
The patent segments transition information into two distinct components: allowable information (what actions are permitted) and execution information (what actions are being executed). This segmentation allows the system to provide complete information while maintaining clarity and reducing perceived complexity through structured organization of the information.

AI summary
When transitioning from both prohibition state that prohibit a specific action and a hand release during an execution of the autonomous driving to a specific action permission state that permits a driver to execute a specific action other than a driving operation, a presentation control device presents information indicating that the transition is allowable prior to information indicating that the transition is executed. When transitioning from a hand release permission state that prohibits the specific action and permits hand release from a steering wheel to the specific action permission state, the presentation control device presents the information indicating that the transition is allowable and the information indicating that the transition is executed at a same time.
