Driver Information Display for Vehicle Lighting Status Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face challenges in providing drivers with clear and timely information about the status of their vehicle's lights, which is crucial for safety and optimal use of driver assistance systems, especially in varying lighting conditions and automation levels.
Innovation Solution
A driver information system that generates a graphic ego object representing the vehicle, depicting its lighting status and environment, using sensors and computing units to output a driver information display that includes the vehicle's lighting state, road conditions, and automation level, allowing for intuitive driver intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a comprehensive driver information system is implemented to provide detailed vehicle status information, then driver awareness and safety are improved, but device complexity increases
Solution Approach 1:
The patent creates a graphic copy (virtual representation) of the ego vehicle that mirrors the actual vehicle's lighting status. This graphical copy allows the driver to perceive vehicle status intuitively without complex physical indicators, resolving the contradiction by providing comprehensive information through a simplified visual interface rather than multiple physical systems
Solution Approach 2:
The patent introduces a display unit as an intermediary between the vehicle's lighting apparatus and the driver. This mediator translates complex electrical and mechanical states into intuitive visual representations, allowing comprehensive status information to be communicated without requiring the driver to understand complex system operations
2Ease of operation
If detailed vehicle status information is provided to the driver, then ease of operation is improved, but loss of information increases due to information overload
Solution Approach 1:
The patent applies local quality by selectively highlighting specific features of the graphic ego vehicle based on the actual lighting status. Instead of displaying all possible information uniformly, the system emphasizes only relevant local characteristics (e.g., illuminated headlamps, taillamps, or signal lamps), making the information both comprehensive and easily processable
Solution Approach 2:
The patent uses color changes in the graphic ego vehicle to encode different lighting states. By varying colors to represent different lamp statuses, the system conveys multiple pieces of information through intuitive visual cues that are easy to process and do not contribute to information overload

AI summary
A method for operating a driver information system in an ego vehicle is provided, wherein an operating state of a lighting apparatus of the ego vehicle is detected, and a driver information display is generated and output. The driver information display comprises a graphic ego object which represents the ego vehicle. In this context, the ego object comprises a rear depiction of the ego vehicle, wherein the ego object is generated depending on the detected operating state.
