Vehicle Key Presence Alerts With Occupant-Aware Theft Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle security systems fail to provide adequate warnings or notifications when a digital key or biometric information leaves a vehicle while it is started, or when a driver exits with a smart key still inside, leading to potential security issues.
Innovation Solution
A vehicle system that includes an authentication key system, occupant sensor, display, and controller to identify the starting authentication key, detect the presence of an assistant driver, and provide notifications or warnings based on the location of authentication keys and the driver's status, using sensors like image, radar, and weight sensors, and communicating with mobile devices to lock or unlock doors accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle provides warnings when authentication keys leave the vehicle, then vehicle security is improved, but false warnings occur when assistant drivers are present
Solution Approach 1:
The system applies different warning rules to different spatial locations within the vehicle. It distinguishes between the driver's seat and other seats, and between the presence of authentication keys in different locations. This localized approach allows the system to provide accurate warnings only when genuinely needed, avoiding false alarms while maintaining security.
Solution Approach 2:
The warning system dynamically adjusts its behavior based on real-time conditions. It continuously monitors the presence of authentication keys, identifies assistant drivers through image recognition, and changes warning status accordingly. The system transitions between different operational states (warning active/inactive) based on dynamic environmental factors.
2Adaptability or versatility
If the vehicle uses multiple authentication key types, then authentication flexibility is improved, but tracking key location becomes more complex
Solution Approach 1:
The authentication key system is designed to universally handle multiple key types (physical keys, digital keys, biometric authentication) through a unified tracking mechanism. The controller implements a general-purpose key management function that can identify and track any authentication key regardless of its specific type, simplifying the overall system architecture.
Solution Approach 2:
The controller acts as an intermediary between various authentication key types and the warning system. It receives authentication status information from different key sources, processes this information through a unified interface, and generates appropriate warning signals. This intermediary layer abstracts the complexity of multiple key types from the rest of the system.
3Reliability
If the vehicle provides notifications through multiple channels, then notification reliability is improved, but system complexity increases
Solution Approach 1:
The notification system merges multiple communication channels (display screen, audio output, mobile device notifications) into a unified notification framework. The controller manages all notification outputs through a single coordinated system, ensuring that warnings are delivered through the most appropriate channel while reducing overall system complexity compared to separate independent notification systems.

AI summary
A vehicle includes an authentication key system for identifying an authentication key, an occupant sensor for detecting an occupant and generating occupant information, a display to display information regarding vehicle operation, and a controller to control the authentication key system, the occupant sensor, and the display, wherein the controller is further configured to identify a starting authentication key used to turn on the vehicle, identify a driver's getting off in a state in which the vehicle is turned on, identify whether an assistant driver is present inside the vehicle based on the occupant information, and control the display to provide a notification that the starting authentication key has been removed from the vehicle or a notification of vehicle theft warning based on whether the starting authentication key or another authentication key is present and whether the assistant driver is present in the vehicle, after the driver gets off the vehicle.
