Automotive Lamp Optical Coding for Dispatched Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying a dispatched vehicle in densely populated regions or at night is challenging due to reduced visibility, especially when distinguishing vehicle license plates is difficult under low light conditions.
Innovation Solution
A vehicle terminal and mobile terminal system that uses an automotive lamp to transmit a user identification code via optical signals, utilizing binary codes like Morse or ASCII, allowing vehicles to be identified from a distance using flashing frequencies imperceptible to humans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle license plate is used for identification, then the vehicle can be identified by its unique number, but the visibility is reduced in densely populated regions or at night
Solution Approach 1:
The patent introduces an automotive lamp as an intermediary device to display the vehicle identification code. Instead of relying directly on the license plate visibility, the system uses the lamp to project the identification information, thereby solving the visibility problem while maintaining accurate identification.
Solution Approach 2:
The patent replaces the passive mechanical license plate system with an active optical signaling system. The automotive lamp converts the identification code into visible light signals, substituting the need for direct visual inspection of the license plate with an optical communication method.
2Ease of operation
If the automotive lamp flashes to transmit information, then the identification can be communicated from a distance, but the flashing may cause user inconvenience or discomfort
Solution Approach 1:
The patent employs periodic flashing of the automotive lamp to transmit identification information in a coded manner. By controlling the flash pattern to represent binary code, the system efficiently communicates information while managing the flashing intensity and pattern to minimize user discomfort.
Solution Approach 2:
The patent adjusts parameters of the automotive lamp such as flash frequency, duration, and intensity to optimize both information transmission effectiveness and user comfort. By carefully selecting these parameters, the system achieves clear identification communication while reducing harmful flashing effects.

Data Source
AI summary
A mobile terminal for identifying a dispatched vehicle using an automotive lamp includes at least one processor and a storage medium storing a computer-readable instruction. When executed by the at least one processor, the computer-readable instruction causes the at least one processor to transmit a vehicle call request including a user identification code, to receive an optical signal output from the vehicle based on the vehicle call request, and to identify whether the vehicle is the dispatched vehicle based on the received optical signal. The optical signal includes the user identification code output through the automotive lamp.
