Lane-Change Intent Signaling for Adaptive Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control methods for safe lane changing are inadequate as they rely solely on distance calculations, which can lead to lane changing failures and safety accidents due to changes in surrounding vehicle driving strategies.
Innovation Solution
A vehicle control method that outputs a prompt message to surrounding vehicles indicating its intention to change lanes, determines the driving state prediction information based on feedback, and generates a driving strategy to either change lanes or stay in the current lane, thereby improving safety and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lane changing is determined solely by distance calculation, then the lane changing process is simple and fast, but the safety and reliability of lane changing deteriorates due to unexpected changes in surrounding vehicle driving strategies
Solution Approach 1:
The system performs preliminary actions by sending prompt messages to surrounding vehicles before executing lane changing, and predicts their driving state in advance. This allows the host vehicle to assess potential risks beforehand and adjust the lane changing strategy accordingly, improving safety without requiring complex real-time response mechanisms
Solution Approach 2:
The system introduces feedback by monitoring the driving state predictions of surrounding vehicles in response to prompt messages. This feedback loop enables the host vehicle to understand whether surrounding vehicles will maintain their current driving strategy, thereby improving lane changing reliability through information-based decision making
2Reliability
If the current distance-based lane changing method is used, then the control logic is simple, but lane changing failures and safety accidents occur due to changes in surrounding vehicle driving strategies
Solution Approach 1:
The system uses prompt messages as an intermediary communication tool between the host vehicle and surrounding vehicles. These messages serve as a medium to convey lane changing intent and elicit predictable responses from surrounding vehicles, making their driving intent detectable without requiring direct observation of their internal decision-making processes
