Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lane-keeping systems for commercial vehicles often fail to provide a safe and adaptive steering assistance, leading to critical situations due to inappropriate torque application, especially in varying vehicle dimensions and environments.
Innovation Solution
An adaptive lane-keeping system with an input module for sensor data, an evaluation module for determining vehicle position, a lane-keeping module for controlling the steering system based on a dynamic torque profile, and a change module that adjusts the profile in response to environmental changes, vehicle dimensions, and driver input, using sensors like cameras and radar for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lane-keeping system with fixed torque profile is used, then the system structure is simple, but the system cannot adapt to different vehicle dimensions and environments, leading to unsafe steering assistance
Solution Approach 1:
The patent implements a dynamic lane-keeping profile that can be adjusted in real-time based on detected environmental conditions and vehicle dimensions. The torque profile is no longer fixed but adapts dynamically to changing circumstances, allowing the same system structure to serve multiple vehicle types and environments effectively.
Solution Approach 2:
The system changes the parameters of the lane-keeping profile (torque values, steering angles) based on detected vehicle dimensions and environmental conditions. By modifying these parameters rather than the overall system architecture, the patent achieves adaptability while maintaining relatively simple system structure.
2Manufacturing precision
If a fixed torque profile is applied to all commercial vehicles, then the control logic is simple, but the system steers too far in one direction or the other for specific vehicle dimensions
Solution Approach 1:
The patent applies different torque profile characteristics to different regions of the lane-keeping operation based on vehicle dimensions and environmental context. Instead of a uniform approach, the system tailors the torque application locally to match specific driving situations and vehicle characteristics, improving steering precision.
Solution Approach 2:
The system uses sensor data to continuously monitor vehicle position, lane markings, and environmental conditions, then adjusts the torque profile accordingly. This feedback mechanism allows the control logic to adapt to specific vehicle dimensions and prevent excessive steering corrections.
3Reliability
If the lane-keeping profile is dynamically adjusted based on environment, then the driving safety and comfort are improved, but the computational requirements and system complexity increase
Solution Approach 1:
The system pre-defines multiple lane-keeping profiles corresponding to different vehicle types and environmental conditions. Rather than computing entirely new profiles in real-time, the system selects and adjusts from pre-configured options, reducing computational requirements while maintaining safety improvements.
