Autonomous Vehicle Repositioning for Buffer Zone Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in avoiding collisions with objects within a buffer zone while parked, particularly when other vehicles or obstacles encroach on this zone, leading to potential convergence and collision risks.
Innovation Solution
A vehicle adjustment system using sensors and processing components to detect objects within the buffer zone and determine an alternate position to move the vehicle, adjusting the buffer zone dimensions and providing control signals to driving components to reposition the vehicle, potentially to another parking space or lot, based on sensor data and occupant preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle remains stationary in its current position, then parking convenience is maintained, but collision risk increases when objects encroach on the buffer zone
Solution Approach 1:
The system performs preliminary detection of objects within the buffer zone before a collision can occur. When an encroaching object is detected, the system proactively repositions the vehicle to a different parking space, preventing the collision risk from materializing while maintaining parking functionality.
Solution Approach 2:
The system transitions the vehicle from a static parked state to a dynamic repositioning state when buffer zone encroachment is detected. This dynamic response allows the vehicle to adapt its position based on real-time sensor data, balancing collision avoidance with parking convenience.
2Reliability
If the buffer zone dimensions are increased to enhance safety margin, then collision prevention improves, but the area available for parking is reduced
Solution Approach 1:
The system establishes a predetermined buffer zone with appropriate dimensions before parking occurs. This preliminary buffer zone configuration ensures adequate safety margins are in place while minimizing the impact on available parking space by using the smallest effective dimensions.
Solution Approach 2:
The system dynamically adjusts the effective buffer zone parameters based on detected conditions. When objects approach or encroach on the buffer zone, the system modifies its response thresholds and repositioning parameters to maintain safety while optimizing space utilization.
3Measurement precision
If the system continuously monitors the buffer zone for encroaching objects, then collision detection accuracy improves, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring of the buffer zone at predetermined time intervals rather than continuous monitoring. This periodic detection approach maintains adequate object detection accuracy while significantly reducing energy consumption compared to continuous sensor operation.
Solution Approach 2:
The system uses the vehicle's existing sensor infrastructure and processing capabilities to perform buffer zone monitoring, leveraging already-powered components. This self-service approach minimizes additional energy requirements while maintaining detection precision.
Data Source
AI summary
A vehicle adjustment system includes one or more processors configured to receive data from one or more sensors coupled to a vehicle that is in a stationary position. The one or more processors are also configured to analyze the data to determine whether an object is within a buffer zone surrounding the vehicle while the vehicle is in the stationary position. In response to determining that the object is within the buffer zone while the vehicle is in the stationary position, the one or more processors are configured to provide control signals to one or more driving components of the vehicle to reposition the vehicle to an alternate position.
