Autonomous Vehicle Operation Device Interface for Immediate Action Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of changing routes or plans in autonomous vehicles increases the operational steps, making immediate action changes difficult for occupants.
Innovation Solution
A vehicle operation device with a presenting unit and an instruction unit that displays the current and next actions of an autonomous vehicle, allowing occupants to intuitively select and instruct changes through a touch panel interface, ensuring safe and immediate action modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays detailed route options and multiple passing places, then the occupant can make informed decisions about route changes, but the operational steps increase and complicate the interface
Solution Approach 1:
The patent extracts only the essential route change information (current action and next action) from the complete route data, displaying it separately from detailed passing places. This allows the occupant to make informed decisions without being overwhelmed by operational complexity.
Solution Approach 2:
The route information is segmented into distinct components: current action, next action, and passing places. Each component is displayed separately, allowing the occupant to focus on the immediate actions required while having access to detailed information when needed.
2Reliability
If the system requires multiple steps to change route or plan, then comprehensive control is maintained, but immediate action changes are prevented
Solution Approach 1:
The system performs preliminary validation of route change requests before execution. The presenting unit checks whether the requested action is safe and permissible, and only then allows the occupant to proceed with the route change, ensuring reliability while maintaining ease of operation.
Solution Approach 2:
The system provides immediate feedback to the occupant about the safety and permissibility of requested actions. The presenting unit informs the occupant whether a route change can be executed, allowing for quick decision-making while maintaining safety through real-time validation.
3Ease of operation
If the presenting unit shows only current action, then the interface remains simple, but the occupant cannot anticipate future actions or plan accordingly
Solution Approach 1:
The presenting unit segments the display into current action and next action sections. This maintains interface simplicity by showing only two actions at a time, while still providing future action information that allows the occupant to plan ahead.
Solution Approach 2:
The system displays the next action in advance before it is executed, allowing the occupant to anticipate future vehicle behavior and make informed decisions about whether to approve or modify the planned action.
