Vehicle Parking Space Detection via V2V Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for finding vehicle parking spaces in congested areas either require significant infrastructure investments or lack the flexibility to allow instantaneous location of available spaces upon arrival, as they often require reservations or are not adaptable to uncertain arrival times.
Innovation Solution
A method where a vehicle detects its own change from a parked to a vacating condition using onboard sensors and communicates this information to neighboring vehicles via a data bus and communication link, allowing real-time detection of available parking spaces without the need for extensive infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detectors and lighted electronic signage are installed at each parking space, then drivers can be directed to available parking spaces, but large infrastructure investments are required
Solution Approach 1:
The parked vehicle itself serves as the detector by using its own sensors to detect when it is parked and when it vacates the space. The vehicle communicates this information autonomously without requiring external detection infrastructure.
Solution Approach 2:
The patent replaces the mechanical/electronic detection infrastructure (detectors, signage) with a communication-based system where vehicles use data buses and communication links to transmit parking status information to neighboring vehicles.
2Reliability
If a centralized parking reservation system is used, then drivers can reserve parking spaces online, but drivers must make reservations before arrival which is time consuming and difficult when arrival time and destination are uncertain
Solution Approach 1:
The system performs preliminary detection and communication of parking status by vehicles themselves before other vehicles need to search for parking spaces. The parked vehicle proactively communicates its status rather than waiting to be detected.
Solution Approach 2:
The system establishes a feedback loop where parked vehicles continuously communicate their status to neighboring vehicles, and searching vehicles receive real-time updates about available spaces without needing to make prior reservations.
3Reliability
If traditional parking detection systems are installed, then parking space availability can be monitored, but the systems lack flexibility to allow instantaneous location of available parking upon arrival
Solution Approach 1:
The system is dynamic and adaptable because it uses existing vehicle communication infrastructure that can instantly transmit status changes. When a vehicle vacates a space, the information is immediately communicated to neighboring vehicles without fixed infrastructure constraints.
Solution Approach 2:
The system uses universal vehicle communication components (data buses, communication links) that already exist in modern vehicles for other purposes, making the parking detection system flexible and adaptable to various vehicle types and scenarios without requiring dedicated infrastructure.

AI summary
A method and system of the invention locates an available vehicle parking space. In the method, parked information indicative of a parked condition is stored in a first vehicle. The first vehicle may detect a change in condition from the parked condition to a vacating condition. The first vehicle then communicates the change in condition from the first vehicle to a neighboring searching vehicle and the searching vehicle detects the change.
