Dynamic Passage Width Adjustment Between Stationary Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems and driver assistance systems often fail to provide sufficient passage for road users, such as pedestrians or bicyclists, when vehicles are parked or stationary, especially in tight spaces or congested areas, as they do not adequately consider the effect of stationary traffic on passage width.
Innovation Solution
A system that determines the intention of a road user to cross a passage between two vehicles, calculates the required passage width based on the user's nature, and adjusts the distance between vehicles using sensors and communication to ensure a safe and sufficient gap, utilizing cameras, LIDAR, radar, and V2X communication to actuate the vehicles and maintain the passage width during the crossing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If vehicles are parked or stationary in congested areas with minimal distance to other vehicles, then parking space utilization is improved, but passage width for road users deteriorates
Solution Approach 1:
The system dynamically adjusts the distance between stationary vehicles based on detected passage needs. When a road user's intention to cross is detected, the vehicles automatically adjust their positions to enlarge the passage width, transforming the static parking configuration into a dynamic adaptive system that responds to real-time requirements
Solution Approach 2:
The system implements a feedback mechanism where sensors continuously monitor for road users and their crossing intentions. When a need is detected, the system communicates with the vehicles to adjust their positions, and after passage completion, the vehicles return to their original positions, creating a closed-loop control system that responds to environmental feedback
2Productivity
If autonomous driving systems maintain minimal distance between vehicles, then productivity is improved, but safety for crossing road users deteriorates
Solution Approach 1:
The system performs preliminary detection of road users and their crossing intentions before they actually attempt to cross. By detecting intentions in advance (through sensors monitoring road user behavior and positioning), the system can prepare and execute passage enlargement before the crossing situation becomes critical, ensuring safety without compromising normal driving efficiency
Solution Approach 2:
The system takes preliminary anti-action by detecting potential hazards (road users intending to cross) before they materialize into dangerous situations. The system proactively adjusts vehicle positions to prevent potential conflicts, rather than reacting after a problem occurs, thereby maintaining both safety and efficiency
3Reliability
If passage width is enlarged to accommodate road users, then safety is improved, but parking space utilization deteriorates
Solution Approach 1:
The system employs periodic action by temporarily enlarging the passage width only during the specific time period when a road user needs to cross. After the crossing is completed, the vehicles return to their original minimal-distance positioning. This periodic adjustment ensures safety when needed while maintaining optimal parking space utilization during normal conditions

AI summary
An intention of a road user to traverse a passage between a first vehicle and a second vehicle is determined. A required width of the passage is determined based on a nature of the road user. A current width of the passage is determined. Upon determining the current width of the passage is less than the required width of the passage, a drive of at least one of the first vehicle or the second vehicle is actuated to increase the current width of the passage at least to the required width of the passage.
