Vehicle Localization via Wireless Action Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for localizing a motor vehicle in a parking lot, especially when multiple vehicles are present, face challenges in efficiently and reliably identifying the correct vehicle for transfer from a starting to a destination position, as they lack a method to distinguish between vehicles accurately.
Innovation Solution
A method and apparatus that transmit a request to a motor vehicle to perform a specific action via a wireless communication network, check if the action is performed, and authenticate the vehicle, allowing for localization by identifying the vehicle that responds to the action, using a combination of communication, checking, and authentication devices within a parking lot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a request is transmitted to multiple motor vehicles via wireless communication network, then the request may reach several vehicles, but it becomes difficult to identify which vehicle is the predetermined target vehicle
Solution Approach 1:
The system transmits a request to perform a specific action to multiple vehicles, then monitors for the actual execution of that action. The vehicle that performs the requested action provides feedback that confirms its identity as the target vehicle, enabling reliable identification without complex additional hardware.
Solution Approach 2:
The target vehicle identifies itself by voluntarily performing the requested action in response to the transmission request. This self-service approach allows the vehicle to demonstrate its identity through action rather than requiring active identification systems.
2Measurement precision
If traditional localization methods are used without action-based verification, then the system is simpler, but it cannot reliably distinguish the correct vehicle among multiple vehicles
Solution Approach 1:
The system sends a preliminary request to perform a specific action before finalizing vehicle identification. This preliminary action serves as a verification step that ensures precise localization by confirming the target vehicle is the one that responds with the expected action.
Solution Approach 2:
The monitoring system observes whether vehicles perform the requested action and uses this feedback to confirm precise localization. The feedback loop of request-transmission, action-execution, and verification enables accurate identification without excessive time loss.
3Reliability
If the system monitors all vehicles for action execution, then accurate localization is achieved, but the energy consumption and system complexity increase
Solution Approach 1:
The system extracts only the essential verification element - monitoring for the specific requested action - rather than continuously monitoring all vehicle parameters. This extraction approach maintains high authentication reliability while minimizing energy consumption by focusing monitoring resources on the critical verification task.

AI summary
A method, apparatus, and computer program for localizing a motor vehicle including transmitting via a wireless communication network configured within a parking lot, for a predetermined motor vehicle, a request that the predetermined motor vehicle carry out a predetermined action. After transmission of the request, a check whether a motor vehicle located within the parking lot is carrying out or has carried out the predetermined action. If the result of the check is that a motor vehicle located within the parking lot is carrying out or has carried out the predetermined action, the motor vehicle is authenticated as the predetermined motor vehicle and the predetermined motor vehicle is localized at a current position of the motor vehicle.
