Remote Parking Path Replanning After Mid-Route Vehicle Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
A vehicle may become unable to proceed in a traveling direction halfway through a travel path due to obstacles, preventing the user from reaching a target parking position and necessitating manual intervention.
Innovation Solution
A parking support device equipped with a path generation unit, travel control unit, and determination unit that generates and adjusts travel paths, detects obstacles, and communicates with an external device to specify alternative movement destinations when a vehicle is unable to proceed, enabling remote control to navigate around or return to a safe position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle is remotely operated through a communication terminal while a door of the vehicle is not locked, then the user can remotely operate the vehicle, but the user cannot get on the vehicle due to obstacles or the like when the vehicle stops halfway through a travel path
Solution Approach 1:
The determination unit continuously monitors the vehicle's travel status and detects when the vehicle has stopped halfway through a travel path. This feedback mechanism enables the system to recognize abnormal situations and trigger appropriate responses, allowing the user to receive notifications and provide remote instructions to move the vehicle to a accessible location.
Solution Approach 2:
The travel control unit dynamically adjusts the travel path based on user instructions received through the communication terminal. When the user specifies a new destination, the system recalculates and executes a modified travel route, enabling flexible adaptation to changing conditions and user needs during remote operation.
2Extent of automation
If the vehicle follows a predetermined travel path to reach a target parking position, then the parking process is automated, but the vehicle cannot deviate from the path when obstacles are encountered
Solution Approach 1:
The system maintains automated operation while enabling dynamic path adjustment. The travel control unit can modify the predetermined travel path based on user instructions, allowing the vehicle to deviate from the original route when obstacles are encountered or when directed by the user, thus combining automation with adaptability.
Solution Approach 2:
The communication terminal serves as an intermediary between the user and the vehicle's travel control system. Through this intermediary, the user can provide instructions to adjust the travel path, enabling remote control and adaptation without requiring manual intervention or breaking the automated operation flow.
3Reliability
If the vehicle stops at a stop position due to an obstacle on the travel path, then the vehicle safety is maintained, but the user cannot access the vehicle and the parking process is interrupted
Solution Approach 1:
The determination unit detects when the vehicle has stopped halfway through a travel path and notifies the user through the communication terminal. This feedback enables the user to understand the situation and provide remote instructions to move the vehicle to a location where the user can safely access it, resolving the accessibility issue while maintaining safety.
Solution Approach 2:
The system enables the user to remotely service the situation by providing instructions through the communication terminal. The user can specify a new destination and the travel control unit will execute the path adjustment, allowing the user to self-resolve the accessibility problem without needing to physically approach the vehicle.

AI summary
A parking support device that can improve convenience when a vehicle has become unable to proceed halfway through a travel path is provided. A parking support device 160 includes: a travel control unit 176 configured to generate control information for causing an own-vehicle 5 to travel in accordance with a travel path R1, the travel control unit 176 configured to output the generated control information to a vehicle control unit 150; and a determination unit 177 configured to determine whether the own-vehicle 5 has become unable to proceed in a traveling direction corresponding to the travel path R1 and has stopped halfway through the travel path R1. When having determined that the own-vehicle 5 has stopped, the determination unit 177 causes a wireless communication unit 110 to transmit information to an operation terminal 10, the information indicating the travel path R1 and a place at which the vehicle has stopped on the travel path R1. When having received, from the operation terminal 10, specification information specifying a place to which the own-vehicle 5 is to be moved, the travel control unit 176 sets, as a travel path R2 of the own-vehicle 5, a path through which the own-vehicle 5 is to be moved to the specified place, and the travel control unit 176 outputs, to a vehicle control unit 150, control information for causing the own-vehicle 5 to move to the specified place.
