Vehicle Daytime Running Light Dynamic Illumination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle lighting apparatuses fail to provide adequate brand identification in darkness and are prone to disturbing light reflections under poor weather conditions, especially when the daytime running light is driven to a high illumination level.
Innovation Solution
A lighting apparatus with a drive device that adjusts the illumination level of the daytime running light based on the status of the low-beam and/or high-beam light and weather conditions, reducing the illumination level when low-beam or high-beam lights are on and further reducing it under poor weather conditions to minimize disturbing reflections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the daytime running light is driven to a high illumination level in darkness, then brand identification is improved, but disturbing light reflections occur under poor weather conditions
Solution Approach 1:
The daytime running light illumination level is made dynamically adjustable with three distinct operating levels. The control unit automatically selects between a first illumination level (higher brightness for brand identification), a second illumination level (reduced brightness to minimize reflections), and a third illumination level (off or minimal brightness) based on detected ambient light conditions and weather parameters, thereby adapting the illumination intensity to current environmental conditions
2Use of energy by moving object
If the daytime running light is switched off with low-beam and/or high-beam light on, then energy consumption is reduced, but brand identification is lost in darkness
Solution Approach 1:
Instead of completely switching off the daytime running light when low-beam and/or high-beam lights are activated, the system changes the illumination parameter to a reduced second illumination level. This allows the daytime running light to remain visible for brand identification purposes while consuming less energy than full illumination, and the control unit can further adjust to a third illumination level based on ambient light detection
3Object-affected harmful factors
If the daytime running light is driven at a low illumination level with low-beam and/or high-beam light on, then disturbing light reflections are minimized, but brand identification capability is reduced
Solution Approach 1:
The control unit incorporates ambient light detection and weather parameter evaluation to dynamically adjust the daytime running light illumination level. By continuously monitoring environmental conditions and providing feedback to the illumination control, the system can select between different illumination levels to maintain brand identification visibility while minimizing disturbing reflections under poor weather conditions

AI summary
A lighting apparatus for a motor vehicle includes a daytime running light device, a low-beam, high-beam, or low- and high-beam light device, and a drive device operable to drive an illumination level of the daytime running light device. With the low-beam and/or high-beam light device switched off, the drive device drives the daytime running light device so as to have a first illumination level. With the low-beam and/or high beam light device switched on, the drive device drives the daytime running light device so as to have a second illumination level. With the low-beam and/or high-beam light device switched on and with poor weather conditions, the drive device drives the daytime running light device so as to have a third illumination level. The second illumination level is less than or equal to the first illumination level. The third illumination level is less than the second illumination level.
