Autonomous Parking Start Control Using Safe-Zone Location Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems for self-driving vehicles do not adequately ensure the safety of people around the vehicles during parking operations, as they do not account for the presence of users and passers-by in the vicinity.
Innovation Solution
A parking assist system that includes a self-driving vehicle, an administrator device, and a mobile terminal device, where the administrator device acquires and determines the location of the vehicle and the user's mobile device to ensure they are in specified safe areas before initiating parking, preventing unsafe interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the administrator device does not verify location before parking initiation, then the parking operation can start immediately improving productivity, but the safety of people around the vehicle deteriorates
Solution Approach 1:
The system performs preliminary location verification by acquiring the user's location information via mobile terminal and determining whether the user is within the specified area before allowing parking initiation. This preliminary safety check ensures that users are in safe zones before the self-driving vehicle begins autonomous parking maneuvers, resolving the contradiction by preventing harmful situations before they can occur.
2Object-affected harmful factors
If the system requires location verification within specified area, then safety of users is improved, but the complexity of the parking system increases
Solution Approach 1:
The system introduces a mobile terminal as an intermediary device to handle location verification. The mobile terminal communicates with the administrator device to transmit user location information, which the administrator device then uses to determine whether the user is within the specified area. This intermediary approach maintains user safety while distributing system complexity across multiple components rather than concentrating it in the self-driving vehicle alone.
3Object-affected harmful factors
If the administrator device acquires and verifies object location, then harmful interactions are prevented improving safety, but the time required for parking operation increases
Solution Approach 1:
The system implements feedback by continuously monitoring user location through the mobile terminal and providing real-time information to the administrator device. The administrator device uses this feedback to determine whether the user is within the specified area and to control the initiation of parking operations. This feedback mechanism ensures safety by only allowing parking when users are in safe zones, while the automated nature of the feedback loop minimizes time loss compared to manual safety checks.

AI summary
A parking assist system includes: a self-driving vehicle that performs automatic driving from a getting-off area to a parking location in a parking area; an administrator device that transmits a guidance route to the parking location and a parking start instruction to the self-driving vehicle; and a mobile terminal device that communicates with the administrator device. The administrator device includes: a location information acquisition unit configured to acquire an object location indicative of a location of the self-driving vehicle or the mobile terminal device; a location determination unit configured to determine whether the object location is within a specified area; and a driving setting unit configured to: instruct the self-driving vehicle to start parking when the object location is within the specified area; and not to instruct the self-driving vehicle to start parking when the object location is not within the specified area.
