Steering Angle Visualization With Haptic Lane Boundary Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lane keeping assistance systems and lane departure warning systems do not provide visual and haptic information to drivers about the gap left inside a safety boundary or the steering angle needed to stay centered in a lane, leading to traffic congestion and safety issues due to distracted drivers and unexpected maneuvers.
Innovation Solution
A vehicle safety system that determines the current steering angle and displays it relative to a steering angle scale, providing torque, vibration, and haptic feedback to guide the driver in maintaining a recommended steering angle, while visualizing safety boundaries and zones of recommended steering angles to prevent lane deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional lane keeping assistance systems and lane departure warning systems are used, then basic lane monitoring is provided, but visual and haptic information about steering angle and safety boundaries is not provided to drivers
Solution Approach 1:
The system implements feedback by displaying the current steering angle on a scale and providing haptic feedback through the steering wheel when the vehicle approaches lane boundaries. This closed-loop feedback mechanism informs the driver about their steering input and its effect on vehicle position, enabling better lane keeping without requiring complex autonomous control systems.
Solution Approach 2:
The patent introduces an intermediary display system that translates complex sensor data about vehicle position and steering angle into simple visual representations on a scale. This intermediary layer makes abstract positioning information comprehensible to the driver without requiring complex processing or additional hardware.
2Reliability
If no visual and haptic feedback is provided to drivers, then system complexity is reduced, but driver awareness of steering angle and lane position is insufficient leading to distracted driving and safety issues
Solution Approach 1:
The system enhances driving safety by providing continuous feedback about vehicle position relative to lane boundaries. The haptic feedback through the steering wheel and visual display create an intuitive connection between driver input and vehicle response, reducing distracted driving incidents without requiring complex autonomous safety systems.
Solution Approach 2:
The feedback system is segmented into distinct functional components: a display component for visual information, a haptic component for tactile feedback, and a control component for processing sensor data. This segmentation allows the system to achieve high reliability through multiple independent safety channels while keeping each individual component relatively simple.
3Ease of operation
If detailed steering angle visualization and haptic feedback systems are implemented, then driver guidance is improved, but the system requires more complex hardware and software integration
Solution Approach 1:
The system achieves ease of operation by making the steering wheel serve multiple functions: it remains the primary steering control while also functioning as a haptic feedback device. This multi-functionality provides intuitive driver guidance without requiring separate control devices or complex integration between independent systems.
Solution Approach 2:
The patent merges the display system, sensor system, and steering control system into an integrated architecture where information flows seamlessly between components. By combining these functions into a unified system rather than separate independent systems, the overall integration complexity is reduced while maintaining comprehensive driver guidance capabilities.
