Perpendicular Parking Guidance Using a Blocking Line for Safe Corrections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems struggle to reliably prevent collisions during perpendicular parking by ensuring the vehicle remains visible to following traffic, as they rely on complex and unreliable line-of-sight determinations and reference points that vary with vehicle design and parking direction, leading to potential collisions due to unexpected maneuvers.
Innovation Solution
A method that defines a blocking line through the vehicle, independent of surrounding vehicles, to ensure the traffic space is kept clear until no further corrective maneuvers are required, using a computer-implemented system to manage automatic lateral and longitudinal guidance, issuing signals or warnings to drivers to ensure safe parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the vehicle enters the perpendicular parking space deeply to complete the parking maneuver, then the parking position is reached, but the driver's view of following traffic is obstructed and collision risk increases
Solution Approach 1:
The system determines in advance whether corrective maneuvers are required by analyzing the trajectory before execution. If corrective maneuvers are needed, the system prevents the vehicle from entering the parking space deeply in the first place, thereby avoiding the dangerous situation before it arises. This preliminary assessment and preventive action resolve the contradiction by ensuring parking position accuracy is achieved without creating obstruction scenarios.
2Object-affected harmful factors
If the line of sight is used to determine vehicle position relative to following traffic, then visibility is maintained, but the determination becomes complex and computationally intensive
Solution Approach 1:
The invention extracts the essential safety requirement from the complex line-of-sight concept and reduces it to a simple binary determination: does the trajectory require corrective maneuvers? This extraction eliminates the need for complex computational geometry calculations while maintaining the safety function. The system only needs to assess whether the vehicle will need to re-enter traffic, which is a straightforward logical check rather than a complex visual obstruction calculation.
3Manufacturing precision
If the vehicle performs corrective maneuvers to reach the parking position, then accurate parking is achieved, but following traffic may accelerate and cause collision
Solution Approach 1:
The system applies preliminary anti-action by preventing the creation of dangerous situations before they occur. Instead of reacting to following traffic acceleration after it happens, the system proactively determines whether corrective maneuvers are required and prevents deep entry into the parking space if corrections are needed. This anticipatory prevention counteracts the potential harmful effect of following traffic acceleration before the conflict arises.
