Vehicle Wireless Positioning via Single Transceiver Antenna Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems require cumbersome and time-consuming manual adjustments by passengers and drivers to configure settings based on personal preferences, and existing position determination technologies are complex and resource-intensive.
Innovation Solution
A system that determines the position of a wireless access device relative to a vehicle using beacon messages and a network of antennas, allowing for automatic configuration of vehicle systems based on the device's position and user authentication, utilizing a single transceiver to process signals from multiple antennas and employing machine learning for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a one to one ratio of transceivers to antennas is used for position determination, then position determination capability is improved, but hardware resources and system complexity increase significantly
Solution Approach 1:
The patent combines multiple antenna signals into a single transceiver unit. The transceiver processes signals from multiple antennas simultaneously, merging the functionality of what would traditionally require separate transceivers for each antenna. This reduces hardware complexity while maintaining position determination capability through signal processing techniques that analyze phase and amplitude differences across the antenna array.
Solution Approach 2:
The single transceiver is designed to handle signals from multiple antennas, making it a multi-functional component. It performs signal reception, processing, and position calculation duties that would traditionally be distributed across multiple dedicated transceivers. This universal transceiver reduces overall system complexity while preserving measurement precision.
2Adaptability or versatility
If manual adjustment of vehicle settings is implemented for each passenger, then personalized settings can be achieved, but the process becomes cumbersome and time consuming
Solution Approach 1:
The system automatically detects passenger presence and determines their position within the vehicle using the antenna network. Based on this position information, the system self-configures appropriate settings without requiring manual passenger intervention. The vehicle system serves itself by autonomously adapting to passenger needs, eliminating the time-consuming manual adjustment process while maintaining personalized settings.
Solution Approach 2:
The system uses feedback from the antenna signal measurements to continuously monitor passenger position and automatically adjust vehicle settings accordingly. The position determination system provides real-time feedback about where passengers are located, and this feedback triggers automatic configuration of appropriate settings for each detected passenger zone.
