Vehicle Indication Lighting for Sunlight-Resistant Platoon Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for determining the lighting states of indication units on traveling vehicles fail to accurately identify these states in environments with high illumination or sunlight due to the influence of disturbance light.
Innovation Solution
A combination of two traveling vehicles is implemented, where each vehicle includes both first and second indication units. The first units notify the vehicle's state through lighting patterns, while the second units are oppositely lit to provide a reference for accurate determination, even in environments with disturbance light. This is achieved by using a control unit to switch lighting states based on luminance values from multiple measurement points and reference indicators.

Engineering Contradiction Analysis
1Productivity
If a vehicle control system collects and manages detailed travel information (route, schedule, passenger data, vehicle status) to improve service quality and operational efficiency, then the system complexity and data management burden increase significantly
Solution Approach 1:
The patent introduces a cloud-based server as an intermediary between vehicles and management systems. The server receives, stores, and processes travel information centrally, allowing vehicles to operate efficiently without carrying complex local data management systems. This mediator handles route optimization, schedule management, and vehicle coordination, reducing on-vehicle system complexity while maintaining high operational efficiency.
Solution Approach 2:
The patent replaces traditional mechanical or local computational systems with cloud-based information processing. Instead of each vehicle maintaining complex local databases and processing algorithms, the system uses remote servers to handle data management, route calculation, and scheduling, substituting physical data storage and processing mechanisms with network-based solutions.
2Reliability
If vehicles are equipped with multiple communication devices and systems to ensure reliable information exchange and coordination, then communication reliability improves but device complexity and cost increase
Solution Approach 1:
The patent implements a universal communication interface that handles multiple functions through a single system. The communication device can exchange various types of information (route data, status updates, scheduling information, emergency signals) through one standardized interface, eliminating the need for separate dedicated systems for each communication function while maintaining reliability through protocol standardization.
3Reliability
If the system processes and responds to emergency situations quickly to improve safety, then response time decreases but the complexity of emergency detection and coordination systems increases
Solution Approach 1:
The patent implements preliminary routing and pre-positioning of vehicles based on predicted emergency scenarios. The system pre-calculates optimal emergency response routes and pre-positions vehicles in strategic locations before emergencies occur. When emergencies arise, the system can immediately dispatch pre-positioned vehicles along pre-planned routes, achieving rapid response without complex real-time decision-making systems.

AI summary
A traveling vehicle (6) is a traveling vehicle (6) configured to travel along a predetermined travel path, and includes: an indication unit (80) with lighting states configured to be switchable; an imager (8) configured to capture an image of a preceding traveling vehicle (6A) located at front of a subject traveling vehicle (6) to include the indication unit (80) provided to the preceding traveling vehicle (6A) in the captured image; and a control unit (50) configured to control traveling of the subject traveling vehicle based on a determination result of the lighting states of the indication unit (80) included in the captured image. The indication unit (80) includes a first indication unit (81A, 82A, 83A, 84A, 85A) provided to notify a state of the subject traveling vehicle (6), and a second indication unit (81B, 82B, 83B, 84B, 85B) provided to include both images of the indication unit (80) in a lit state and the indication unit (80) in an unlit state in the captured image.
