Steering Collision Avoidance for A-Pillar Blind Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AEB systems fail to detect and prevent collisions from obstacles in the A-pillar blind spot during vehicle turns due to limited detection range, leading to frequent accidents.
Innovation Solution
A vehicle steering automatic collision avoidance system that integrates a wide-angle camera and autonomous emergency braking, using a driving control computer to provide steering collision-avoidance decisions based on urban or highway road information, extended turning area determination, and tire trajectory prediction, activating a wide-angle camera to detect obstacles in the blind spot and trigger emergency braking if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional AEB system with radar sensors is used, then rear-end collision prevention is effective, but detection of obstacles in A-pillar blind spots during turns is insufficient
Solution Approach 1:
The patent introduces a wide-angle camera to detect obstacles in the A-pillar blind spot area that is not covered by traditional forward-facing radar sensors. This adds a new detection dimension (lateral/blind spot area) to complement the existing forward detection capability, enabling the system to detect obstacles during turning maneuvers while maintaining straight-ahead collision prevention.
2Adaptability or versatility
If the detection range is extended to cover blind spots, then obstacle detection during turns improves, but system complexity increases
Solution Approach 1:
The wide-angle camera serves multiple functions: it detects obstacles in A-pillar blind spots during turns, provides visual information for the driving control computer to determine collision risk, and works in conjunction with the AEB system for comprehensive safety monitoring. This multi-functionality justifies the added component while maximizing its utility across different driving scenarios.
Solution Approach 2:
The driving control computer acts as an intermediary that integrates information from both the traditional AEB radar system and the wide-angle camera. It processes data from both sources, determines whether a collision risk exists in the blind spot area, and coordinates the AEB system response. This centralized integration manages system complexity by providing a single decision-making hub.
3Reliability
If emergency braking is activated for blind spot obstacles, then collision avoidance during turns improves, but false braking warnings may increase
Solution Approach 1:
The system implements a feedback mechanism where the driving control computer continuously monitors obstacle detection data from the wide-angle camera, evaluates collision risk based on vehicle steering state and obstacle position, and only triggers AEB when genuine risk is confirmed. This feedback loop filters out false alarms by requiring multiple conditions to be met simultaneously (obstacle in blind spot area + vehicle turning + collision risk determined).
