Reserved Vehicle Identification via Terminal Light Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for identifying a reserved autonomous vehicle require users to compare figures displayed on a smartphone with those on the vehicle's door, making intuitive recognition difficult.
Innovation Solution
A reserved vehicle control system that acquires positional information of both the terminal device and the reserved vehicle, determines if they are within a predetermined distance, and allows the user to control a light-emitting device on the vehicle via the terminal device, enabling intuitive identification by turning on or off the lights based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If figure comparison method is used for vehicle identification, then vehicle identification function is achieved, but user recognition intuitiveness deteriorates
Solution Approach 1:
The patent creates a visual copy of the vehicle's light emission pattern by displaying it on the user's terminal device screen. Instead of requiring the user to compare abstract figures, the system captures and reproduces the actual light pattern from the vehicle, allowing intuitive recognition through direct visual matching between the terminal display and the real vehicle lights.
2Ease of operation
If display device is installed on vehicle for identification, then user recognition is improved, but device cost and complexity increase
Solution Approach 1:
The patent introduces the terminal device (smartphone or tablet) as an intermediary between the vehicle's light emission system and the user's visual perception. Instead of installing a display on the vehicle, the system uses the user's existing terminal device to capture and display the light pattern, eliminating the need for additional vehicle-mounted display hardware while maintaining intuitive recognition.
Solution Approach 2:
The patent leverages the user's existing terminal device, which they already possess and use, to perform the identification function. The terminal device's camera and display capabilities are utilized without requiring the vehicle to provide additional identification hardware, making the system self-sufficient regarding display resources.
3Reliability
If figure comparison method is used, then identification function is achieved, but identification time increases
Solution Approach 1:
The system creates an immediate visual copy of the vehicle's light pattern on the terminal device screen, allowing the user to perform instant visual matching rather than comparing abstract figures. This direct visual reproduction significantly reduces the cognitive processing time required for identification while maintaining accurate vehicle recognition.

AI summary
A reserved vehicle control method includes a step of acquiring positional information of a terminal device, a step of acquiring positional information of a reserved vehicle, a step of determining whether a distance between the terminal device and the reserved vehicle is a predetermined value or less, in accordance with the positional information of the terminal device and the positional information of the reserved vehicle, and a step of outputting, to the terminal device, allowing information indicating that an operation on a light-emitting device mounted on the reserved vehicle is allowed, when determining that the distance between the terminal device and the reserved vehicle is the predetermined value or less.
