Elevator User Notification for Autonomous Vehicle Boarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving vehicles struggle to reliably notify elevator users about their use, especially in noisy environments or when voice announcements are not clearly heard, leading to potential delays or disruptions in elevator usage.
Innovation Solution
An autonomous driving vehicle operation system that includes a control unit to create and transmit elevator usage information, which is processed by an elevator control unit to output voice and visual announcements within the elevator, ensuring clear communication of the vehicle's elevator use to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voice output from the autonomous driving vehicle is used to notify elevator users, then the structure remains simple, but the notification reliability deteriorates in noisy environments or when users cannot hear clearly
Solution Approach 1:
The notification system is segmented into multiple independent channels: voice output from the autonomous vehicle and visual display within the elevator. This segmentation allows the system to maintain simplicity while improving reliability by providing redundant notification paths that can operate independently of each other.
Solution Approach 2:
The elevator's internal display system acts as an intermediary between the autonomous vehicle's notification and the users. Instead of relying solely on the vehicle's voice output to reach users directly, the system uses the elevator's display as a mediator to present the notification visually, ensuring reliable communication even when audio notifications fail.
2Device complexity
If only voice output is used for elevator notification, then the device complexity remains low, but the information transmission completeness deteriorates when users cannot hear or understand the announcement
Solution Approach 1:
The notification system applies different qualities to different notification channels: auditory quality for voice output and visual quality for display. This local quality differentiation ensures that information is transmitted in the most effective format for each channel, compensating for limitations in one modality with strengths in another.
Solution Approach 2:
The system transitions from a single-dimensional audio notification to a multi-dimensional notification system that includes both audio and visual dimensions. This dimensional expansion allows information to be conveyed through multiple sensory pathways, reducing information loss when one pathway is insufficient.
3Device complexity
If the autonomous driving vehicle uses elevator voice announcements, then the structure remains simple, but the notification effectiveness deteriorates when many people are talking or noise levels are high
Solution Approach 1:
The system provides prior cushioning by delivering the notification through both voice and visual channels before the elevator boarding process begins. This dual-channel approach预先 compensates for potential audio transmission failures due to noise or competing conversations, ensuring the notification is received despite adverse acoustic conditions.

AI summary
An operation system performs autonomous operation by using an operation server for an autonomous driving vehicle. The operation server includes a memory unit containing three-dimensional map data. An autonomous driving vehicle connects to the operation server via a wireless network. A vehicle control unit creates a traveling route based on the map data received and, when an elevator of a building is to be used, creates elevator usage information and elevator control information, including the boarding and exiting floors. The elevator is equipped with an elevator control unit that is connected to the operation server to control ascending and descending of an elevator cage. A control unit of the autonomous driving vehicle transmits the elevator usage information and the elevator control information to the elevator control unit. The elevator control unit gives a voice announcement from a voice output unit in the elevator cage.
