3D Driver Information Display for Road Curvature Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to quickly and reliably notify drivers of the road course ahead, particularly in situations where precise knowledge of the roadway is crucial for safe driving, such as navigating curves or changes in road conditions.
Innovation Solution
A driver information system that uses sensors like cameras, lidar, and radar to detect the road course and generate a graphic lane object display, which includes the radius of curvature, allowing drivers to visualize the road ahead in a 3D perspective, with dynamic updates based on vehicle movement and road conditions, and provides criticality alerts through highlighting features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional driver assistance systems provide information about road conditions, then driver awareness is improved, but the information is not presented in a visually intuitive and easily perceptible manner
Solution Approach 1:
The patent transforms 2D road course data into a 3D perspective visualization that appears to extend into the distance, creating a depth dimension that makes the road layout more intuitive and easier to comprehend at a glance
Solution Approach 2:
The system uses color coding to represent different road conditions and features (e.g., green for clear road, yellow for curves, red for hazards), enabling drivers to quickly grasp critical information through color perception rather than text or symbols
2Measurement precision
If detailed information about road course is provided, then measurement precision is improved, but the complexity of the display increases
Solution Approach 1:
The system extracts only the most critical road course information (curvature radius, direction changes, hazards) from the complete sensor data set and presents it in a simplified visual format, eliminating unnecessary details while preserving essential safety information
Solution Approach 2:
The road course is divided into discrete segments or zones with different visual characteristics based on their properties (e.g., straight sections, curves, hazard zones), allowing complex information to be presented as a series of simple, distinguishable visual elements
Data Source
AI summary
A method for operating a driver information system in an ego vehicle is provided, in which a course of the road lying in front of the ego vehicle in the driving direction is detected including a radius of curvature of a curve, and a driver information display is generated and output. The driver information display comprises a graphic lane that represents the detected course of the road. The graphic lane object comprises the detected radius of curvature of the curve in a perspective depiction.
