Automatic Parking Route Suggestion Before Multi-Route Junctions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to efficiently perform automatic parking in multiple parking lots around a vehicle's current position, often requiring the vehicle to return to a parking lot before initiating parking assistance.
Innovation Solution
A parking assistance device that acquires vehicle position and multiple routes to parking positions, judges the feasibility of automatic parking, and suggests parking before a junction, allowing the vehicle to proceed without returning to a parking lot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle returns to a parking lot before initiating parking assistance, then the parking assistance can be executed properly, but the parking efficiency deteriorates due to additional travel time
Solution Approach 1:
The system performs preliminary judgment of parking feasibility and suggests parking before the vehicle reaches a junction, allowing the driver to make a decision in advance. This prevents the need to return to a parking lot later, as the parking suggestion is made at the optimal moment when multiple routes are still accessible.
Solution Approach 2:
The system continuously monitors vehicle position, calculates multiple routes to parking positions, and provides feedback to the driver about parking feasibility. This real-time feedback loop enables the driver to make informed decisions about whether to park at the current location or continue driving, improving overall parking efficiency.
2Adaptability or versatility
If the system calculates multiple routes to parking positions, then parking options increase, but the system complexity increases
Solution Approach 1:
The route calculation unit serves multiple functions: it calculates routes to multiple parking positions, determines the best parking position based on various criteria, and provides this information to the suggestion unit. This multi-functionality reduces the need for separate dedicated components for each task.
Solution Approach 2:
The system merges the route calculation, parking position selection, and parking suggestion functions into a single integrated parking assistance device. This consolidation reduces system complexity compared to having separate independent systems for each function.

AI summary
A parking assistance device that assists parking of a vehicle includes: a position acquiring unit that acquires a vehicle position as a position of the vehicle; a route acquiring unit that acquires a plurality of routes as routes from the vehicle position to a plurality of parking positions; a judging unit that judges whether execution of automatic parking is possible, the automatic parking being such that the vehicle travels on any one of the plurality of routes and is parked in the parking position; a suggesting unit that, when execution of the automatic parking is possible, suggests the automatic parking before the vehicle passes through a junction of the plurality of routes; and a parking control unit that executes the automatic parking using the selected route.
