Vehicle Column Traveling Visual Output Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems for column traveling lack effective integration of visual system outputs to enhance coordination and safety among vehicles in a column, particularly in terms of direction indication, lighting, and visual information sharing.
Innovation Solution
A vehicle control system equipped with a communication unit, output unit, and controller that enables intra-column cooperation by synchronizing visual system outputs such as direction indicators, lighting, and visual information across vehicles in a column, including front and rear lighting, direction indication, and side visual information, to facilitate coordinated column traveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual system outputs are synchronized across vehicles in a column, then coordination and safety among vehicles are enhanced, but device complexity increases due to communication and control requirements
Solution Approach 1:
The visual system outputs are segmented by vehicle position (head vehicle, intermediate vehicles, rearmost vehicle), with each vehicle performing specific synchronization tasks appropriate to its position in the column, reducing overall system complexity while maintaining coordination
Solution Approach 2:
Instead of the head vehicle controlling all visual outputs, the system inverts the control flow by having each vehicle independently control its own visual system outputs based on received communication information, simplifying the control architecture
2Stability of the object's composition
If direction indicating information is synchronized across the column, then coordination during lane changes is improved, but loss of time occurs due to waiting for synchronization
Solution Approach 1:
The head vehicle transmits direction indicating information to other vehicles in advance before actual lane change execution, allowing intermediate and rearmost vehicles to prepare their visual outputs without causing synchronization delays during the actual maneuver
3Loss of information
If rear output units display visual information from the head vehicle, then information sharing across the column is improved, but device complexity increases due to additional output units and processing
Solution Approach 1:
The rear output units are designed with multi-functionality, capable of displaying both local vehicle information and visual information received from the head vehicle, eliminating the need for separate dedicated display systems and reducing overall device complexity

AI summary
A vehicle control system applied to a column traveling system includes: a communication unit that is disposed in a host vehicle, and configured to be able to transmit/receive communication information to/from another vehicle in a column that travels while being included in the column as a group together with the host vehicle; an output unit that is disposed in the host vehicle, and configured to be able to output a visual system output related to the sense of sight to the outside of the host vehicle; and a controller configured to be able to perform intra-column cooperation processing of controlling the output unit to cause a plurality of the visual system outputs to cooperate with each other in the entire column based on the communication information. As a result, the vehicle control system applied to the column traveling system enables appropriate column traveling to be performed.
