Parking Path Replanning for Vehicles Stuck Mid-Maneuver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often get stuck halfway through a travel path due to obstacles, preventing them from reaching a target parking position, which complicates user access and increases inconvenience.
Innovation Solution
A parking support device equipped with a path generation unit, travel control unit, and determination unit that generates a travel path, controls vehicle movement, and determines if the vehicle is stuck, transmitting information to an external device to adjust the path and facilitate movement to a specified location.

Engineering Contradiction Analysis
1Extent of automation
If the vehicle travels automatically to a target parking position through a generated path, then parking automation is improved, but the vehicle may get stuck halfway due to obstacles, reducing reliability
Solution Approach 1:
The determination unit continuously monitors the vehicle's travel status along the generated path and detects when the vehicle has stopped halfway. This feedback mechanism triggers automatic communication with the external device to request alternative path generation, ensuring the automation system adapts to unexpected obstacles and maintains reliability.
Solution Approach 2:
Before the vehicle completes its travel, the system proactively communicates with the external device when a stop is detected, requesting alternative paths in advance. This preliminary action prevents complete travel failure and ensures continuous automation by preparing backup routes before the current path becomes completely blocked.
2Object-affected harmful factors
If the vehicle stops halfway due to obstacles, then travel safety is improved by avoiding collision, but user convenience deteriorates as the user cannot easily access the vehicle
Solution Approach 1:
The system provides feedback to the external device about the vehicle's stopped position and status. The external device then generates alternative paths that avoid the obstacle, allowing the vehicle to resume travel safely. This maintains both collision avoidance and user convenience by enabling remote path adjustment without requiring physical user intervention at the stopped location.
Solution Approach 2:
The external device acts as an intermediary between the obstacle situation and the vehicle control system. It receives information about the stopped vehicle, calculates alternative paths, and sends control instructions back to the vehicle, enabling safe path modification without direct user presence at the vehicle location.
3Ease of operation
If the vehicle remotely operates without user presence, then operational convenience is improved, but the system cannot respond to unexpected obstacles, reducing adaptability
Solution Approach 1:
The determination unit provides feedback about unexpected obstacles and vehicle stops to the external device. This enables the remotely operated vehicle to detect and communicate obstacle situations, allowing the external operator or automated system to generate alternative paths and maintain adaptability despite remote operation.
Solution Approach 2:
The vehicle system automatically detects when it has stopped due to obstacles and initiates communication with the external device to request alternative paths. This self-service capability allows the remotely operated vehicle to respond to obstacles autonomously without requiring constant user monitoring, maintaining both remote convenience and obstacle adaptability.

AI summary
When having determined that an own-vehicle has become unable to proceed in a traveling direction corresponding to a travel path of the own-vehicle and has stopped halfway through a travel path, a parking support device transmits information to an operation terminal, the information indicating a travel path and a place at which the vehicle has stopped on the travel path. When having received, from the operation terminal, specification information specifying a place to which the own-vehicle is to be moved, the parking support device sets, as a travel path of the own-vehicle, a path through which the own-vehicle is to be moved to the specified place, and outputs, to a vehicle control unit, control information for causing the own-vehicle to move to the specified place.
