Vehicle Control Device for Accurate Parking State Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic valet parking systems often fail to accurately manage parking states, leading to discrepancies between designated and actual parking positions, resulting in incorrect guidance to available spaces.
Innovation Solution
A vehicle control device equipped with a communicator, recognizer, and generator that communicates with a management device to accurately assess and report parking states by recognizing surrounding vehicles and transmitting information about occupied parking spaces, ensuring correct parking guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a vehicle is guided to a parking space based on management information, then the vehicle can be automatically parked, but the managed parking position may differ from the actual parking position causing guidance errors
Solution Approach 1:
The system implements feedback by having vehicles transmit their actual parking position information back to the management device. The management device receives position information from vehicles after parking and compares it with the designated parking positions, enabling correction of management information to match actual parking states.
Solution Approach 2:
The management device acts as an intermediary that coordinates between multiple vehicles and the parking space management system. It collects position information from vehicles, processes this information to determine actual parking states, and uses this to generate accurate guidance for other vehicles.
2Productivity
If the management device manages parking states of multiple vehicles, then parking guidance can be provided, but discrepancies occur between managed and actual parking positions
Solution Approach 1:
The system establishes a feedback loop where vehicles automatically transmit their parking position information to the management device after parking. This feedback mechanism allows the management device to continuously update and correct the managed parking states to reflect actual conditions.
Solution Approach 2:
Vehicles autonomously report their own parking position information to the management device without requiring manual intervention. Each vehicle serves itself by automatically providing position data, which collectively enables the system to maintain accurate parking state information.
3Productivity
If the system guides vehicles to vacant parking spaces, then parking efficiency is improved, but vehicles may be guided to positions that are actually occupied
Solution Approach 1:
The management device receives actual position information from vehicles and uses this feedback to verify which parking spaces are truly vacant. By comparing designated vacant spaces with actual vehicle positions, the system can accurately identify available parking spaces for guidance.
Solution Approach 2:
The system replaces manual or static parking space monitoring with automated electronic position reporting from vehicles. Instead of using physical sensors or manual checks, the system uses digital communication to obtain real-time position information from vehicles.

AI summary
A vehicle control device includes a communicator which communicates with a management device that guides a vehicle capable of automatedly traveling to a target parking space with reference to management information representing parking states of a plurality of parking spaces, a recognizer which recognizes a surrounding state of the vehicle, and a generator which generates parking state information including information representing whether other vehicles are parked in parking spaces which the vehicle passes on the basis of a result recognized by the recognizer and transmits the parking state information to the management device using the communicator.
