Parking Assistant Device V2X Zone Definition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking systems fail to consider rules and etiquette associated with parking zones, relying solely on occupancy status, which is inadequate for both autonomous and non-autonomous vehicles, and do not effectively communicate valid parking spaces or rules to vehicles.
Innovation Solution
A vehicle-to-everything (V2X) communication system that enables two-way communication between vehicles and parking assistant devices, providing information on valid parking zones and rules, which can be user-defined or learned over time, and includes monitoring of parking area status to alert users of unauthorized parking events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one-way communication from server to vehicle is used, then system complexity is reduced, but parking zone rules and etiquette cannot be effectively communicated to vehicles
Solution Approach 1:
The patent introduces a parking assistant device as an intermediary component deployed at the parking area that stores parking zone information and rules locally. This device communicates with vehicles via V2X communication, enabling two-way exchange of parking information without requiring complex server-vehicle direct communication. The intermediary holds the parking zone database and rules locally, allowing vehicles to receive comprehensive parking information while maintaining relatively simple communication architecture.
2Ease of operation
If predefined uniform parking zones are used, then ease of identification is improved, but adaptability to different parking scenarios and rules is reduced
Solution Approach 1:
The patent implements dynamic parking zone definitions where zone boundaries, validity, and rules are not fixed but can be updated and adapted. The parking assistant device stores and communicates parking zone information that can change based on different scenarios, times, and conditions. This allows the system to adapt to various parking situations (commercial, residential, temporary events) while maintaining clear zone definitions for vehicle identification.
Solution Approach 2:
The system allows parking zone parameters such as boundaries, validity periods, and associated rules to be modified based on different scenarios. The parking assistant device can update zone information dynamically, enabling the same physical space to serve different parking purposes at different times while maintaining clear, identifiable zone definitions for vehicles.
3Extent of automation
If server-based web service is used, then centralized control is improved, but communication efficiency and real-time information delivery are reduced
Solution Approach 1:
The patent implements preliminary action by pre-loading parking zone information and rules into the parking assistant device at the parking area before vehicles arrive. This allows vehicles to receive parking information quickly through local V2X communication without requiring real-time server queries. The centralized server maintains the master database and updates the parking assistant devices in advance, enabling efficient real-time information delivery while maintaining centralized control.
Data Source
AI summary
Techniques are described for defining and delivering parking area information to a vehicle. The parking area information can be sent by a parking assistant device associated with a parking area and in response to receiving one or more messages from a vehicle system of the vehicle. Messages from the vehicle system indicate a location of the vehicle and are used by the parking assistant device to track a movement of the vehicle. The parking area information is sent in one or more responses messages from the parking assistant device and can include a rule for determining whether the vehicle is permitted to park in an unoccupied parking zone within the parking area or indicate a result of applying the rule.
