Reserved Lane Change Control Using Existing Warning Countermeasures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving assistance systems are inadequate in preventing unauthorized use of reserved lanes, as they do not effectively warn drivers who have activated their turn signal, and require additional processing resources to implement specific countermeasures.
Innovation Solution
A driving assistance method that detects lane changes and determines authorization to use reserved lanes, activating countermeasures if the lane change is detected without proper authorization, using existing resources for both voluntary and involuntary lane changes, including sensory warnings and corrective actions like resistive torque on the steering wheel or differential braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assistance systems activate specific countermeasures for unauthorized lane changes, then the effectiveness of preventing unauthorized use of reserved lanes is improved, but the hardware and software resources required increase
Solution Approach 1:
The patent applies universality by making the existing lane change warning device perform multiple functions: it serves both as a warning device for involuntary lane changes and as a countermeasure system for preventing unauthorized lane changes into reserved lanes. The management system reuses the same hardware components (warning device, sensors, processing unit) for both functions, eliminating the need for dedicated hardware and reducing system complexity while maintaining effectiveness.
Solution Approach 2:
The patent merges the unauthorized lane change prevention function with the existing lane change warning system. The management system combines the detection of unauthorized lane changes with the activation of the warning device, merging multiple functions into a single integrated system that shares common hardware resources, thereby improving reliability without increasing device complexity.
2Reliability
If driving assistance systems provide comprehensive warnings for lane changes, then the safety of lane change operations is improved, but the complexity of the warning system increases
Solution Approach 1:
The management system makes the lane change warning device universal by using it for both warning drivers about involuntary lane changes and preventing unauthorized lane changes into reserved lanes. This multi-functional approach improves safety comprehensively while avoiding the complexity increase that would result from implementing separate warning systems for each function.
3Productivity
If the system uses the same countermeasures for both voluntary and involuntary lane changes, then the resource utilization is improved, but the ability to provide differentiated responses decreases
Solution Approach 1:
The patent applies dynamics by making the system's response adaptive based on the detected scenario. The management system dynamically determines whether a lane change is voluntary or involuntary by analyzing multiple parameters (turn signal status, lane type, authorization), and activates countermeasures only when appropriate. This dynamic adaptation allows the system to reuse resources efficiently while maintaining the ability to provide differentiated responses through intelligent control logic rather than hardware differentiation.
