Leaning Vehicle Headlight Control for Turn Illumination and Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlight devices for leaning vehicles consume excessive energy for bright lighting during turns, leading to increased energy consumption and heat generation, while providing inadequate illumination for the rider.
Innovation Solution
A headlight device with adaptive front-lighting functionality that adjusts lighting based on vehicle lean angle, designating certain areas as brightly lit or dim to optimize energy use and ensure clear visibility during turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If bright lighting is applied to all areas in the ahead-driving direction, then the rider can see ahead well, but energy consumption and heat generation increase
Solution Approach 1:
The ahead-driving direction is divided into multiple discrete areas (first area, second area, third area, fourth area) with different lighting controls. This segmentation allows selective bright lighting only in necessary areas while keeping other areas dim, resolving the contradiction between providing sufficient illumination and reducing energy consumption.
Solution Approach 2:
Different areas are assigned different lighting qualities based on their specific functional requirements. The first and second areas receive bright lighting for rider visibility, while the third and fourth areas receive dim lighting to reduce energy consumption. This local differentiation resolves the contradiction by optimizing lighting quality spatially.
2Illumination intensity
If bright lighting is applied to all areas in the ahead-driving direction, then the rider can see ahead well, but heat generation increases
Solution Approach 1:
The lighting system segments the ahead-driving direction into multiple areas with different brightness levels. By keeping the third and fourth areas dim rather than brightly lit, the system reduces overall heat generation while maintaining adequate visibility in the first and second areas where the rider needs to see.
Solution Approach 2:
Different thermal characteristics are applied to different areas through selective lighting intensity. The first and second areas have higher temperature/heat output due to bright lighting, while the third and fourth areas have lower heat output due to dim lighting, resolving the contradiction between visibility requirements and heat management.
3Use of energy by moving object
If adaptive lighting control is applied to multiple oblique areas, then energy consumption is reduced, but lighting coverage during turns may be insufficient
Solution Approach 1:
The lighting system dynamically adjusts which areas are brightly lit versus dimmed based on real-time detection of oncoming vehicles and vehicles ahead. When no vehicles are detected, the system can expand bright lighting coverage. When vehicles are detected, the system selectively dims only the necessary areas, maintaining energy efficiency while ensuring adequate coverage where needed.
Solution Approach 2:
The system uses detection information about oncoming vehicles and vehicles ahead as feedback to dynamically control lighting distribution. This feedback mechanism allows the system to reduce energy consumption by dimming areas where vehicles are present while maintaining bright lighting in areas where the rider needs visibility, thus resolving the contradiction between energy savings and lighting coverage.

AI summary
A control device of a leaning vehicle for controlling bright lighting and dim lighting for a plurality of oblique areas. When the leaning vehicle is upright, the control device controls the lighting by designating one or more of the plurality of oblique areas as in a brightly lit area to which adaptive lighting control is applied, and by designating the other oblique areas as in a dim area. The dim area includes an uppermost oblique area. When the leaning vehicle turns left or right, as a lean angle in a direction of the turn increases, the control device controls the lighting by designating a second uppermost oblique area that is located immediately below the uppermost oblique area in the up-down direction as in the brightly lit area, and moving the uppermost oblique area from the dim area to the brightly lit area.
