Lane Change Controller Road Condition Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lane change control systems for vehicles are limited in application and cannot be safely activated on general roads due to the presence of pedestrians, cyclists, or insufficient lane configurations, restricting their use to specific road types like highways.
Innovation Solution
A lane change controller that determines road conditions using GPS, map information, and sensor data to assess whether a lane change is possible, displaying the result to the user and controlling the lane change accordingly, allowing activation only on suitable road types like limited-access roads or highways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lane change control system is activated on general roads, then the convenience and usability of the system is improved, but the safety risk increases due to pedestrians, cyclists, and insufficient lane configurations
Solution Approach 1:
The system applies different operational characteristics to different road types by identifying specific road characteristics (highway, limited-access road, general road) and enabling lane change control only on suitable road types. This localized adaptation allows the system to be versatile across different environments while maintaining safety by restricting operation to appropriate conditions.
Solution Approach 2:
The system dynamically adjusts its operational state based on real-time road condition assessment. By continuously evaluating road type and characteristics, the system can transition between enabled and disabled states, optimizing both adaptability to different road environments and safety through conditional activation.
2Reliability
If lane change control system is restricted to specific road types only, then the safety is improved, but the applicability and convenience of the system deteriorates
Solution Approach 1:
The system implements selective activation based on local road characteristics, enabling lane change control on highways and limited-access roads while restricting it on general roads. This approach maintains high safety standards on restricted road types while preserving system functionality where appropriate.
Solution Approach 2:
The system dynamically determines road type and adjusts operational availability accordingly, creating a flexible safety mechanism that adapts to different driving environments rather than applying a static restriction across all road types.
3Measurement precision
If the system determines road conditions using multiple data sources (GPS, map information, sensor data), then the accuracy of lane change feasibility assessment is improved, but the system complexity increases
Solution Approach 1:
The system divides the road condition determination process into distinct functional modules: GPS receiving module for location data, map information module for road type classification, and sensor data module for surrounding environment detection. This segmentation improves measurement precision through multiple data sources while managing complexity through modular architecture.
Solution Approach 2:
The system integrates multiple data acquisition functions (GPS reception, map data processing, sensor data collection) into a unified road condition determination system. This multi-functional approach enhances assessment accuracy by combining complementary information sources while sharing common processing infrastructure to mitigate complexity increases.
