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

VSEngineering 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

Engineering Contradiction:
Improveroute information completenessVSAvoidoperation steps
Core Design Contradiction:
Loss of informationVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the system requires multiple steps to change route or plan, then comprehensive control is maintained, but immediate action changes are prevented

Engineering Contradiction:
Improvecontrol safetyVSAvoidresponse speed
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #23Feedback

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

Engineering Contradiction:
Improveinterface simplicityVSAvoidfuture action information
Core Design Contradiction:
Ease of operationVSLoss of information

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #10Preliminary action
