Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face challenges in providing drivers with timely and intuitive information about the road ahead, especially regarding curvature and safety requirements, as existing systems often rely on map data that lacks precision and fails to account for real-time changes or hazards.
Innovation Solution
A driver information system that uses sensors like cameras, LIDAR, and radar to detect the road ahead, generating a 3D graphical lane object display with criticality highlighting, allowing drivers to visualize their position and necessary interventions through augmented reality projections, integrating sensor data with map data for enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If map data is used to display road course information, then the system is simple to operate, but the measurement precision and reliability of road curvature information deteriorates
Solution Approach 1:
The system segments road course information display into two distinct components: a 2D map view showing the overall route and a 3D perspective view showing the actual detected road geometry. This segmentation allows each view to serve its specific purpose - the map provides contextual navigation while the 3D view delivers precise curvature information for immediate driving decisions.
Solution Approach 2:
The system transitions from traditional 2D map representation to a 3D perspective representation of the road course. This dimensional change enables the display to convey depth, curvature radius, and spatial relationships more accurately, providing the driver with intuitive understanding of upcoming bends and road geometry that cannot be effectively represented in 2D.
2Device complexity
If traditional 2D display is used for road information, then the device complexity is low, but the driver's situational awareness and understanding of road curvature deteriorates
Solution Approach 1:
The system adds a third dimension to the road information display by presenting the detected road course in a 3D perspective view that mimics the driver's actual view of the road ahead. This dimensional enhancement preserves all the information available in 2D maps while adding critical spatial context about curvature, elevation changes, and road geometry that is essential for situational awareness.
3Reliability
If real-time sensor data is integrated with map data, then the reliability of road course information improves, but the device complexity increases
Solution Approach 1:
The system merges real-time sensor data from the vehicle's detection systems with pre-stored map data to create a unified, accurate representation of the road course. This combination allows the system to detect actual road geometry, curvature, and features dynamically while using map data as a reference framework, thereby improving reliability through multi-source validation.
Solution Approach 2:
The system introduces a road course detection unit as an intermediary component that processes sensor data and reconciles it with map data. This intermediary layer filters, validates, and integrates information from multiple sources before presenting the final road course representation to the display system, managing complexity through structured data processing.
4Reliability
If detailed road curvature information is provided to the driver, then the driver's ability to navigate safely improves, but the information overload and cognitive burden increases
Solution Approach 1:
The system applies local quality by providing detailed road curvature information only in the 3D perspective view where it is most relevant for immediate driving decisions, while keeping the 2D map view simpler for overall route context. This localized information presentation ensures that detailed geometric data is displayed where it adds maximum value without overwhelming the driver with redundant information across all displays.
