Inductive Charging System Unauthorized Vehicle Movement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle theft detection systems fail to reliably detect unauthorized movements of vehicles, particularly during charging processes, as they are not specifically designed for theft detection and may trigger false alarms.
Innovation Solution
Implementing an inductive vehicle charging system that detects vehicle movements by monitoring coil current, voltage, impedance, foreign object detection, living object detection, and positioning sensors to differentiate between authorized and unauthorized movements, outputting a message signal if unauthorized movement is detected, and requiring a specific key and release code for vehicle removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing vehicle theft detection systems are used, then they can detect some vehicle movements, but they cannot reliably detect unauthorized movements during charging processes and may trigger false alarms
Solution Approach 1:
The detection process is segmented into distinct phases: charging process detection and post-charging detection. During charging, the system monitors for unauthorized movements with specific criteria, while after charging, it continues monitoring until authorized movement is detected. This segmentation allows different detection strategies to be applied at different times, improving overall reliability without causing false alarms.
Solution Approach 2:
The system performs preliminary authorization checking before allowing vehicle movement after charging. By requiring verification of authorization status before the vehicle can be driven away, the system prevents unauthorized theft while allowing legitimate users to depart. This preliminary check ensures that only authorized vehicles can leave the charging station.
2Reliability
If multiple detection methods are implemented, then theft detection capability is enhanced, but system complexity increases
Solution Approach 1:
The inductive charging system's existing sensors and monitoring capabilities are made multi-functional. The same coil current monitoring, impedance detection, and positioning systems used for charging control are also utilized for theft detection. This eliminates the need for separate dedicated theft detection hardware, reducing system complexity while enhancing theft detection capability.
Solution Approach 2:
The theft detection function is merged with the charging control system. By combining authorization checking, movement detection, and charging management into a single integrated system, the patent avoids duplicating components and reduces overall system complexity while maintaining comprehensive theft protection.

AI summary
A method for detecting theft of a vehicle, includes the following steps: detecting a vehicle movement by an inductive vehicle charging system, checking the authorization for a detected vehicle movement, and outputting a message signal if an unauthorized vehicle movement is detected. The checking of the authorization for a detected vehicle movement is started after the start of a vehicle charging process.
