Vehicle Dispatch Camera-Based Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for specifying a vehicle in a vehicle dispatch system requires an electronic display to be mounted outside the vehicle, increasing costs.
Innovation Solution
A communication method that transmits target vehicle information captured by onboard cameras to a second apparatus for display, allowing users to specify the vehicle without an external display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an electronic display is mounted outside the vehicle to display vehicle signals, then the user can recognize the vehicle position and specify the target vehicle, but the system cost increases
Solution Approach 1:
The patent transmits the vehicle signal displayed on the user terminal to the vehicle's existing external display device, creating a visual copy of the vehicle's appearance and signal. This allows the user to recognize the vehicle without requiring a separate external electronic display device, thereby reducing system cost while maintaining the ability to identify vehicle position and specifications
Solution Approach 2:
The patent utilizes the vehicle's existing external display device (which is already part of the vehicle's standard equipment) to serve the additional function of displaying vehicle identification signals. This multi-functional use of existing hardware eliminates the need for dedicated external display equipment, reducing overall system cost while achieving the same information transmission goal
2Loss of information
If an electronic display is mounted outside the vehicle, then the vehicle can display identification signals to the user, but the device complexity increases
Solution Approach 1:
The vehicle signal captured by the camera and displayed on the user terminal is transmitted to the vehicle's existing external display device, creating a visual representation of the vehicle's appearance and identification information. This copying approach allows the user to identify the vehicle without adding complex external display hardware
Solution Approach 2:
The vehicle uses its own existing external display device to display its identification signal, rather than requiring a separate display system. The vehicle's display device serves itself to communicate identification information to the user, reducing overall device complexity

AI summary
A communication method for a vehicle dispatch system includes a communication apparatus configured to control communication between a first apparatus and a second apparatus. The first apparatus and the second apparatus are capable of information exchange with each other. The communication apparatus includes a processor. The processor operates to: acquire a position of a boarding point for a user and a current position of a target vehicle to be dispatched to the user; at identification timing at which a determination is made that the current position of the target vehicle belongs to a predetermined area defined with reference to the position of the boarding point, generate target vehicle information using a captured image captured by one or more cameras of the target vehicle; and transmit the target vehicle information to the second apparatus. The second apparatus operates to display the received target vehicle information on a display.
