Vehicle Collision Avoidance via Dynamic Reference Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to dynamically adjust the reference area for collision avoidance based on external loads, leading to potential collisions when traveling with mounted loads, as the initial reference area set during shipment does not account for changes in vehicle dimensions.
Innovation Solution
A vehicle system that includes a camera to acquire external appearance images, sensors to detect objects and impacts, and a controller to dynamically determine a reference area based on the external load, adjusting the alarm and autonomous driving commands accordingly to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reference area is set based on the initial vehicle dimensions during shipment, then the system structure is simple and easy to implement, but the system cannot prevent collisions when external loads are mounted on the vehicle
Solution Approach 1:
The reference area is dynamically adjusted based on the detected position of external loads. The controller modifies the alarm area by extending it in the direction where the load is mounted, making the system adaptive to changing vehicle configurations rather than using a fixed reference area
Solution Approach 2:
The patent replaces complex mechanical measurement systems with image processing technology. The camera captures images of the vehicle and load, and the controller calculates the reference area through image analysis algorithms, substituting physical measurement mechanisms with optical and computational approaches
2Measurement precision
If a fixed reference area is used for alarm notification, then the alarm system is simple to operate, but it cannot provide accurate collision avoidance when vehicle dimensions change due to external loads
Solution Approach 1:
The system performs self-measurement by using the camera to capture images and automatically calculating the reference area based on the detected load position. The vehicle system itself determines its own dimensions without requiring external measurement tools or manual input from users
Solution Approach 2:
The system continuously monitors the vehicle environment using the camera and sensor, detects changes in vehicle dimensions due to loaded objects, and adjusts the reference area accordingly. This closed-loop feedback mechanism ensures the alarm area remains accurate despite changes in vehicle configuration
3Reliability
If the reference area is dynamically adjusted based on external loads, then collision prevention is improved, but the device complexity and image processing requirements increase
Solution Approach 1:
The patent replaces complex mechanical measurement systems with image processing technology. The camera captures images of the vehicle and load, and the controller calculates the reference area through image analysis algorithms, substituting physical measurement mechanisms with optical and computational approaches
Solution Approach 2:
The camera serves as an intermediary device that captures visual information about the load position. This intermediary converts physical load positions into image data that can be processed by the controller to determine the extended reference area
