Wireless Vehicle Seat Localization for Removable Seat Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle seat monitoring systems face challenges in accurately detecting the location and occupancy of removable and interchangeable seats, especially those not easily connected to the vehicle's 12V supply, and in integrating with existing technologies like passive entry passive start (PEPS) systems.
Innovation Solution
The implementation of wireless, independently powered detection systems that use wireless signals to identify seat locations and attributes, such as occupancy and seat belt engagement, and communicate this information to the vehicle's components, potentially integrating with existing PEPS systems and using existing antennas like LF or UWB for location determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless, independently powered detection systems are implemented to monitor removable and interchangeable seats, then the ability to detect seat location and occupancy is improved, but the device complexity increases
Solution Approach 1:
The patent replaces mechanical/wired connection systems with wireless detection systems. The seat monitoring system uses wireless communication protocols to transmit data between seat sensors and the vehicle's control unit, eliminating the need for physical wiring connections to the 12V power supply. This substitution enables monitoring of removable seats while reducing installation complexity.
Solution Approach 2:
The detection system is designed to be independently powered, with each seat unit containing its own power source (such as a battery) and detection components. This self-service capability allows the seat monitoring to function autonomously without requiring connection to the vehicle's electrical system, enabling easy installation and removal of seats while maintaining monitoring functionality.
2Ease of operation
If wireless signal transmission is used for seat monitoring, then the ease of operation is improved, but the reliability of detection may deteriorate due to signal interference
Solution Approach 1:
The patent employs intermediate components such as wireless transceivers and signal processing units that mediate between the seat sensors and the vehicle's control system. These intermediaries handle signal conditioning, error correction, and protocol management to ensure reliable communication despite the wireless nature of the system, maintaining detection accuracy while preserving installation ease.
