Remote Taxi Availability Lamps for Driver Assignment Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in determining the availability of remote driving taxis since there is no clear indication whether a taxi is occupied by a driver.
Innovation Solution
A remote driving taxi system that includes a display lamp on each taxi, controlled by processors based on management information, to indicate availability by turning on or off the lamp depending on the assignment and use state of the taxi.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If no display indication is provided on remote driving taxis, then the system structure remains simple, but users cannot determine whether the taxi is available
Solution Approach 1:
The patent applies color changes through display lamps that change color or illumination state to indicate different availability statuses of remote driving taxis. The display lamp on the taxi body visually communicates whether the vehicle is available for service or currently occupied, solving the information loss problem without requiring complex electronic displays or communication systems.
Solution Approach 2:
The system enables self-service by having the taxi itself display its availability status through onboard display lamps that automatically reflect the current operational state. This eliminates the need for users to actively query the system or for complex communication infrastructure, as the taxi provides its own status information passively and continuously.
2Ease of operation
If a display lamp is added to indicate availability, then user recognition of taxi availability improves, but the device complexity increases
Solution Approach 1:
The display lamp uses color changes or illumination state changes to provide clear visual cues about taxi availability. This simple optical signal is easily recognizable by users from a distance and does not require complex electronic interfaces, buttons, or displays, thereby maintaining ease of operation while minimizing added complexity.
Solution Approach 2:
The availability indication system is segmented into simple, discrete visual signals on the taxi body rather than a complex integrated display system. The display lamp is separated as an independent visual indicator that communicates specific status information, making the overall system easier to implement and maintain while improving user recognition.
3Extent of automation
If the display lamp is controlled by remote driving taxi system, then centralized management is achieved, but communication requirements and system complexity increase
Solution Approach 1:
The system implements feedback by having the display lamp on each taxi automatically reflect the current availability status stored in the central management system. The centralized system updates the status of each taxi based on occupancy and operational data, and this status is automatically displayed on the vehicle without requiring complex real-time communication protocols or automated control algorithms.
Solution Approach 2:
The display lamp acts as an intermediary between the central management system and users. Instead of requiring direct complex communication between the central system and user devices, the lamp provides a simple visual mediation that conveys availability status, reducing communication requirements while maintaining centralized automation.

AI summary
A remote driving taxi system provides a mobility service using remote driving taxis that are driven by remote drivers. Each of the remote driving taxis includes a display lamp configured to indicate whether the remote driving taxi is currently available. Management information includes use states of the remote driving taxis and assignment states between the remote driving taxis and the remote drivers. The remote driving taxi system puts on the display lamp of the remote driving taxi to which the remote driver has already been assigned and that is currently available, based on the management information. Further, the remote driving taxi system puts off the display lamp of the remote driving taxi to which the remote driver has already been assigned and that is currently unavailable, based on the management information.
