Two-Stage Door Sensor Tracking for Vehicle Seating Zone Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems face challenges in accurately identifying the seating zone of a mobile device user within a vehicle, especially when devices are placed in storage areas, leading to ambiguity in determining the owner's location.
Innovation Solution
A two-stage event-driven approach using wireless signal sensors surrounding vehicle doors to capture data snapshots when a door is opened and closed, associating the mobile device with a seating zone based on consistent proximity to the door, and applying settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless signal sensors are used to track mobile device proximity to doors, then seating zone identification accuracy is improved, but system complexity increases due to multiple sensors and two-stage event-driven approach
Solution Approach 1:
The patent divides the vehicle interior into multiple seating zones (driver zone, front passenger zone, rear passenger zones) and places wireless signal sensors at different door locations to track mobile devices in each zone independently. This segmentation allows precise identification of which seating zone a device belongs to by monitoring proximity to specific doors.
Solution Approach 2:
The system captures a first data snapshot when a door is opened to record the mobile device's proximity to the door before the user enters the vehicle. This preliminary action establishes a baseline for determining the device's intended seating zone before the door closes and the user is inside the vehicle.
Solution Approach 3:
The system captures a second data snapshot when the door is closed to verify the mobile device's proximity to the door. By comparing the first and second snapshots, the system confirms whether the device remained close to the door throughout the door opening/closing sequence, providing feedback that validates the seating zone assignment.
2Productivity
If a single data snapshot is used to determine seating zone, then processing speed is improved, but identification reliability deteriorates when devices are placed in storage areas
Solution Approach 1:
The system captures a first data snapshot when a door is opened to record the mobile device's proximity to the door before the user enters the vehicle. This preliminary action establishes a baseline for determining the device's intended seating zone before the door closes and the user is inside the vehicle.
Solution Approach 2:
The system captures a second data snapshot when the door is closed to verify the mobile device's proximity to the door. By comparing the first and second snapshots, the system confirms whether the device remained close to the door throughout the door opening/closing sequence, providing feedback that validates the seating zone assignment.

AI summary
A vehicle may include wireless signal sensors surrounding the doors of the vehicle. A processor of the vehicle may be programmed to capture, from the sensors, a first data snapshot when one of the doors is opened and a second data snapshot when the one of the door is closed, and assign a mobile device to a seating zone associated with the one of the doors when the first and second snapshots both indicate the mobile device is closest to the door.
