Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current headlights and head-up displays (HUDs) provide light distributions independently of topography and object data, leading to unclear visual representations for drivers, potentially causing misdirection.
Innovation Solution
A method and device that determine topography and object data within the driver's field of vision to adjust light distributions, ensuring an undistorted projection that accounts for the driver's perspective, using pixel headlights and HUDs to provide clear visual cues, even under unfavorable conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light distribution is provided independently of topography and object data, then the lighting function can be activated and basic illumination can be provided, but the visual representation becomes unclear and may cause misdirection
Solution Approach 1:
The system performs preliminary determination of topography and object data before generating the light distribution. By pre-acquiring environmental information and processing it through rectification calculations, the system prepares corrected projection data in advance, ensuring accurate visual representation without adding complexity during real-time operation.
2Measurement precision
If topography and object data are considered to adjust light distribution, then visual clarity and accuracy are improved, but the processing complexity and computational requirements increase
Solution Approach 1:
The system introduces an intermediary processing layer that receives topography and object data, performs rectification calculations to compensate for perspective distortions, and outputs corrected light distribution patterns. This intermediary processing step transforms complex environmental data into simplified projection instructions, achieving precise driver perspective representation while managing computational complexity through structured data transformation.

AI summary
The invention relates to a method for providing a lighting function for assisting a driver when driving a motor vehicle, in which the lighting function is activated (10), a light distribution is determined according to the lighting function, a perspective of a driver of the motor vehicle is determined (12) and a projection device of the motor vehicle is controlled (18) in such a way that the projection device outputs light according to light distribution. The invention is based on the object of improving the provision of the lighting function for assisting the driver when driving the motor vehicle. According to the invention it is proposed that topography data from an environment in a field of view of the driver and/or object data from an object in the surroundings in the field of view of the driver are acquired, and the light distribution is determined (14) as a function of the topography data and/or object data and the perspective.
