Auto-Valet Parking Route Planning for Large Vehicle Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking management systems fail to consider vehicle specifications when guiding large vehicles to empty parking blocks, leading to potential traffic congestion due to inability to pass designated routes or park in designated spaces during auto-valet parking.
Innovation Solution
A parking management system that includes a database for vehicle and parking lot information, a target parking position determination unit, and a route generation unit capable of generating guidance routes based on vehicle specifications, allowing for the selection of suitable parking blocks and routes, and automatic vehicle control to navigate these routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a route is designated without considering vehicle specifications, then the parking lot guidance system can operate simply, but large vehicles cannot pass the designated route or park in the designated empty parking block
Solution Approach 1:
The system determines target parking positions based on local conditions including empty parking block positions, passage widths, and vehicle specifications. The route generation unit creates customized routes for each vehicle type, making the guidance system adaptable to different vehicle sizes and turning radii while maintaining ease of operation through automatic determination.
Solution Approach 2:
The system changes routing parameters based on vehicle specifications such as vehicle width and minimum turning radius. The route generation unit adjusts route candidates by adding turning points when vehicles cannot pass through passages, dynamically modifying the route to accommodate different vehicle types while keeping the overall system simple to operate.
2Extent of automation
If auto-valet parking is implemented without route consideration for large vehicles, then automation level increases, but traffic congestion occurs due to vehicles unable to pass designated routes
Solution Approach 1:
The system performs preliminary route verification by checking whether vehicles can pass through passages based on vehicle specifications before generating final routes. The route generation unit proactively adds turning points to route candidates when passage widths are insufficient, preventing traffic congestion before it occurs while maintaining high automation levels.
Solution Approach 2:
The route generation unit acts as an intermediary between the auto-valet parking system and the physical parking lot environment. It mediates route planning by considering vehicle specifications and passage constraints, generating appropriate turning points to enable large vehicles to navigate successfully without causing congestion, thus bridging the gap between automation and physical realities.
3Manufacturing precision
If vehicle specifications are considered in route generation, then route accuracy for large vehicles improves, but system complexity increases
Solution Approach 1:
The system applies partial consideration of vehicle specifications by focusing on critical parameters such as vehicle width and minimum turning radius rather than all possible vehicle characteristics. The route generation unit adds turning points only when necessary based on passage width comparisons, achieving sufficient route accuracy for large vehicles without unnecessarily increasing system complexity.

AI summary
A parking management system is provided that addresses the problem of parking difficulties in auto-valet situations where vehicle size is not taken into account. It includes a target parking position determination unit, a route generation unit, and a vehicle control unit. The determination unit considers parking block sizes, empty vehicle space position, and the own vehicle's size to find a suitable parking spot. The route generation unit creates a guidance route from the entrance to the target parking position. The vehicle control unit autonomously drives the own vehicle along the generated route. The system generates potential routes based on entrance or exit positions and determines a turning point on the route. If the own vehicle can safely navigate the turning point considering parked vehicle sizes and minimum turning radius, that route is selected as the guidance route.
