Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing disembarking support devices lack a method to adjust the output of notification content based on the presence or absence of a passenger in the vehicle during disembarking support.

Innovation Solution

A disembarking support device that includes a processor to judge the presence of a passenger and adjust the output of notification content accordingly, issuing warnings only when a passenger is present and preventing door opening if a moving body is detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If notification content is continuously output to inform passengers of disembarking support status, then safety information is conveyed, but passenger annoyance increases

Engineering Contradiction:

Improvesafety information conveyanceVSAvoidpassenger annoyance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The notification output is dynamically adjusted based on the detected presence or absence of passengers. When passengers are detected, notifications are output to convey safety information; when no passengers are present, notifications are suppressed to reduce annoyance. This parameter-based adaptation resolves the contradiction by changing the notification state according to environmental conditions.

2Device complexity

If disembarking support control is ended based solely on time or door state, then control simplicity is maintained, but notification accuracy deteriorates

Engineering Contradiction:

Improvecontrol logic simplicityVSAvoidnotification timing accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system uses passenger presence detection as feedback to determine when to end disembarking support control and when to output notifications. This feedback mechanism improves notification timing accuracy without significantly increasing system complexity, as the passenger detection function is already part of the vehicle's sensor system.

AI summary

There is provided a processor for executing disembarking support control for protecting a passenger by issuing a warning in case of a moving body approaching a vehicle is present and a door is in an open state in case of the passenger is disembarking from the vehicle, and the processor executes the following processing. Judging whether the passenger is present in the vehicle in case of ending the disembarking support control, executing output control for outputting notification contents for notifying ending of the disembarking support control in case of it is judged that the passenger is present, and not executing the output control in case of the passenger is not present.
