Vehicle Boarding Position Control for Pre-Arrival Ramp Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle ramp systems require users to move to a different location if an obstacle is detected after the vehicle has arrived at the boarding area, causing unnecessary delay in boarding.
Innovation Solution
A vehicle information management device that acquires road surface information before arrival at the boarding area, determining if the ramp can be deployed and proposes a position change if necessary, and adjusts door opening based on obstacle detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If obstacle detection is performed after vehicle arrival at boarding area, then ramp deployment safety is ensured, but boarding time is increased due to user relocation requirements
Solution Approach 1:
The system performs road surface information acquisition and obstacle detection before the vehicle arrives at the boarding area. The determination section evaluates whether the ramp can be deployed at the planned boarding position in advance, allowing the user to be notified of any issues before arrival and eliminating the need for post-arrival relocation.
2Productivity
If early road surface information acquisition is implemented, then boarding efficiency is improved, but system complexity increases due to additional detection infrastructure
Solution Approach 1:
The system introduces a server as an intermediary that receives road surface information from detection devices at boarding areas, processes this information, and communicates with the vehicle's determination section. This distributed architecture allows early obstacle detection without requiring complex detection equipment in each vehicle, thereby improving boarding efficiency while managing system complexity.
3Ease of operation
If obstacle detection is performed before vehicle arrival, then user relocation can be planned in advance, but information acquisition infrastructure is required at boarding areas
Solution Approach 1:
The server acts as an intermediary infrastructure that centralizes the obstacle detection and information management functions. Detection devices at boarding areas transmit road surface information to the server, which then provides this information to approaching vehicles. This allows users to be notified of obstacles before vehicle arrival and plan relocation in advance, while the complex infrastructure is consolidated in the server rather than distributed across all vehicles.

AI summary
A vehicle information management device includes: a processor, wherein the processor is configured to: before a vehicle arrives at a planned vehicle boarding area of a user, acquire road surface information of the planned vehicle boarding area; based on the road surface information, determine whether or not a road surface height of a planned vehicle boarding position, at which the user is waiting at the planned vehicle boarding area, is a height at which a ramp of the vehicle can be deployed; and in a case in which the road surface height is determined to not be a height at which the ramp can be deployed, propose a change of the planned vehicle boarding position to the user.
