Vehicle Slope Measurement for Parking Floor Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking location alert services are inefficient in underground and skyscraper parking environments, where the complexity of parking structures and vehicle positioning make it difficult for drivers to accurately determine the parking floor of their vehicles.
Innovation Solution
An apparatus and method using a processor to measure a vehicle's slope and perform wireless communication to determine the parking floor by comparing the slope with setup values for underground and ground parking lots, adjusting the parking floor value based on slope changes, and alerting the driver through a telematics management system and smartphone application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing parking location alert services are used, then drivers can receive parking location information, but the services become inefficient in underground and skyscraper parking environments with complex structures
Solution Approach 1:
The patent changes the measurement parameter from horizontal GPS coordinates to vertical slope angle. By measuring the slope of the vehicle and comparing it with preset slope values corresponding to different parking floors, the system can accurately determine the parking floor in complex underground and skyscraper environments where traditional GPS-based methods fail.
2Ease of operation
If drivers manually search for their parked vehicles by roaming the parking lot, then they can locate their vehicles, but this consumes excessive time and effort
Solution Approach 1:
The system automatically determines the parking floor by measuring the vehicle's slope and processing the data through the processor. The driver simply needs to start the vehicle and allow the system to automatically calculate and send the parking floor information to their smartphone, eliminating the need for manual searching.
Solution Approach 2:
The system provides real-time feedback to the driver about their parking location. The processor continuously monitors vehicle parameters, determines the parking floor, and sends notifications to the driver's smartphone application, allowing the driver to know immediately where their vehicle is parked.
3Measurement precision
If traditional GPS-based parking alert services are used, then location information can be provided, but accuracy is reduced in underground parking lots with limited signal
Solution Approach 1:
The patent replaces the GPS satellite-based electromagnetic signal system with a mechanical sensing system that measures the vehicle's slope angle. This substitution allows the system to function independently of external signal sources, making it effective in underground parking lots where GPS signals are blocked or limited.

AI summary
An apparatus for alerting a parking floor includes an electronic control unit configured to: determine an entrance of a parking lot; measure a slope of a vehicle; perform wireless communication with an external device through a wireless communication network; determine a current location of the vehicle; determine a gear stage of the vehicle; and compare the slope of the vehicle with a first setup value corresponding to an underground parking lot or a second setup value corresponding to a ground parking lot when the vehicle enters the entrance of the parking lot to determine movement of the vehicle to each floor and determine a parking floor value corresponding to a floor at which the vehicle reaches.
