Vehicle Location Positioning Using Aggregated Client Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GPS-based vehicle location positioning techniques are inaccurate in environments with high-rise buildings and overpasses due to weakened GPS signal strength, leading to unreliable location determination.
Innovation Solution
A method and system where a client terminal acquires vehicle identification and determines location information using Assisted GPS or other positioning technologies, sending this information to a server to determine the vehicle's location, thereby bypassing the need for additional GPS modules and improving accuracy and continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS module is installed on vehicle to obtain location, then location information can be obtained, but GPS signal strength is greatly affected by environment (high-rise buildings, overpasses) leading to inaccurate positioning
Solution Approach 1:
The patent combines multiple positioning methods (GPS positioning, cell tower triangulation, Wi-Fi positioning) into a unified positioning system. The server integrates location data from different sources to determine vehicle location, ensuring accurate positioning even when GPS signals are weak or unavailable due to environmental factors like high-rise buildings and overpasses.
Solution Approach 2:
The patent introduces a server as an intermediary that receives location information from multiple client terminals and determines the vehicle's location based on this aggregated data. This intermediary processes and validates location information from various sources, improving reliability by cross-referencing multiple data points rather than relying solely on direct GPS signals from the vehicle.
2Measurement precision
If GPS signals are used for positioning, then location can be determined, but signal strength may not meet actual needs in challenging environments
Solution Approach 1:
The patent creates a multi-functional positioning system that can operate using different positioning methods depending on environmental conditions. The system universally supports GPS positioning, cell tower triangulation, and Wi-Fi positioning, allowing it to adapt to various scenarios including urban canyons, overpasses, and areas with blocked satellite visibility, ensuring continuous accurate positioning without being limited by GPS signal strength alone.
3Productivity
If vehicle location is determined using GPS module, then positioning can be achieved, but location information may not be obtained in time due to signal blockage
Solution Approach 1:
The patent implements continuous location monitoring through multiple client terminals that continuously send location information to the server. This ensures uninterrupted tracking of vehicle location even when GPS signals are temporarily blocked. The system maintains continuous useful action by aggregating location data from multiple sources over time, preventing gaps in location information and ensuring real-time tracking capability.
Data Source
AI summary
Location positioning methods, devices, systems, and computer-readable mediums are provided. One of the methods includes: receiving a vehicle identification and location information from at least one client terminal; and determining a location of a target vehicle corresponding to the vehicle identification according to the location information. The determining the location of the target vehicle corresponding to the vehicle identification according to the location information comprises: determining location information corresponding to the vehicle identification of the target vehicle received from the at least one client terminal within a set time period; determining a number of occurrences of each piece of the determined location information; and determining the location of the target vehicle corresponding to the vehicle identification according to a piece of the determined location information with a number of occurrences larger than a set threshold.
