Side-Impact Collision Detection via Lateral Displacement Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crash sensing systems fail to detect side-impact collisions in nearby vehicles and respond appropriately, posing challenges for drivers due to increasing distractions and unpredictable vehicle behavior on the road.
Innovation Solution
A system that detects the presence of nearby vehicles and determines their side-impact collision status by analyzing lateral displacement over time intervals, triggering responses such as warnings and countermeasures when thresholds are exceeded, using vehicle-to-vehicle and vehicle-to-infrastructure communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers manually observe and process information about nearby vehicles, then they can detect collision hazards, but the increasing number of distractions and unpredictable vehicle behavior makes timely detection difficult
Solution Approach 1:
The patent replaces manual driver observation and mechanical reaction with an automated sensor-based system that detects lateral displacement of nearby vehicles. Sensors monitor vehicle position continuously, and a controller automatically processes the data to detect side-impact collisions, eliminating the need for driver attention and manual processing.
Solution Approach 2:
The system enables vehicles to autonomously monitor their own lateral displacement and automatically detect collision events without external intervention. The vehicle's own sensors and controllers perform the detection and triggering functions, providing self-service collision monitoring and warning capabilities.
2Reliability
If existing crash sensing systems are used, then basic collision detection is provided, but they fail to identify side-impact collision status of nearby vehicles and respond appropriately
Solution Approach 1:
The patent segments the collision detection function into specific lateral displacement monitoring for side-impact scenarios. Rather than attempting to detect all collision types simultaneously, the system focuses specifically on detecting lateral movement patterns characteristic of side-impact collisions, simplifying the detection logic while improving accuracy for this specific hazard type.
3Ease of operation
If drivers are distracted or prevented from responding to hazards, then collision avoidance becomes difficult, but automated countermeasures can compensate
Solution Approach 1:
The system triggers countermeasures automatically upon detecting a side-impact collision hazard, performing the avoidance action before the driver can react. The automated application of brakes or other countermeasures is initiated immediately when the controller determines a positive collision status, ensuring timely response regardless of driver distraction or impairment.
Data Source
AI summary
A system and method are provided to determine the side-impact collision status of a nearby vehicle or vehicles. If a nearby vehicle has been in a collision, responsive systems may be triggered automatically. Responses may include warning the driver of the host vehicle and/or warning drivers of other vehicles or centralized networks by, among other methods, V2V or V2I communications. Responses may also include automatically triggering countermeasures in the host vehicle.
