Rear Lamp Unit Control System for Vehicle Tailgate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear lamp unit designs face limitations in design flexibility due to the fixed placement of rear lamps on the vehicle body side, which restricts the aperture and lamp unit configuration.
Innovation Solution
A rear lamp unit control system that includes a first lamp on the vehicle body side and a second lamp on the opening-closing body side, with a controller managing their luminous intensities to maintain functionality and visibility regardless of the opening-closing body's state, allowing for equivalent luminous intensity adjustment when the opening-closing body is open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rear lamp unit is provided on the vehicle body side with a fixed aperture design, then the lamp unit structure is simple, but the design freedom of the aperture and lamp unit is limited
Solution Approach 1:
The lamp system is divided into two separate lamp units: a first rear lamp unit provided on the vehicle body side and a second rear lamp unit provided on the opening-closing body side. This segmentation allows each lamp unit to be independently designed and positioned, thereby increasing design freedom for the aperture and lamp configuration while maintaining manageable structural complexity through modular design.
2Adaptability or versatility
If the second lamp is provided on the opening-closing body side to enhance design freedom, then the aperture and lamp unit design flexibility is improved, but the lamp functionality may be compromised when the opening-closing body is open
Solution Approach 1:
The first rear lamp unit and the second rear lamp unit are controlled to operate in coordination with each other. When the opening-closing body is in the open state, the controller makes the first rear lamp unit and the second rear lamp unit emit light at different luminous intensities, ensuring that the combined lighting effect maintains adequate visibility and functionality. This merging of functions compensates for the potential functionality loss of the second lamp when the opening-closing body is open.
Solution Approach 2:
The controller dynamically adjusts the luminous intensity of the first and second rear lamp units based on the state of the opening-closing body. When the opening-closing body transitions between open and closed states, the controller modifies the operating parameters of the lamps to maintain optimal visibility and functionality, thereby ensuring reliable lamp performance across different operational conditions.
3Ease of operation
If the first lamp and second lamp operate at the same luminous intensity regardless of opening-closing body state, then the control system is simple, but the visibility and information transmission may be insufficient when the opening-closing body is open
Solution Approach 1:
The controller dynamically adjusts the luminous intensity of the first and second rear lamp units based on the state of the opening-closing body. When the opening-closing body is in the open state, the controller makes the first rear lamp unit and the second rear lamp unit emit light at different luminous intensities, ensuring that the combined lighting effect maintains adequate visibility and information transmission to the rear.

AI summary
A rear lamp unit control system for a vehicle including: a first lamp provided on a vehicle body side of a vehicle rear face; a second lamp provided on an opening-closing body side of the vehicle rear face; and a controller configured to control the first lamp and the second lamp. When an opening-closing body of the vehicle is in a closed state, the controller is configured to control the first lamp and the second lamp so that the first lamp and the second lamp turn on at different luminous intensities to each other. In response to the second lamp being in need to be turned on when the opening-closing body is in an open state, the controller is configured to turn the first lamp on at a luminous intensity that is equivalent to a luminous intensity of the second lamp when the second lamp is turned on.
