Sensor-Fusion Based Theft System for Wheel Removal Detection

Abstract This paper presents a smart detection system designed to identify unauthorized removal of car wheels, particularly high-value alloy wheels. The system utilizes existing onboard sensors and vehicle electronics to detect theft attempts in real time. It operates through a three-stage process: (1) Angular motion detection using accelerometer and gyroscope data embedded in the vehicle’s Electronic Control Unit (ECU) or stability control system to monitor abnormal tilt—specifically when one side of the vehicle is lifted beyond a threshold of 10-15 degrees; (2) Wheel presence verification via Tire Pressure Monitoring System (TPMS) sensors to identify wheel detachment and check the TPMS value; and (3) Key proximity check, which verifies whether the authorized key fob is near the vehicle. If the key is absent during a suspected theft event, the system confirms unauthorized access. Upon validating these conditions, the system can trigger a tamper-resistant alarm through ECU communication, even if the primary alarm system has been disabled. This multi-layered detection strategy significantly enhances vehicle security by combining motion analysis, wheel monitoring, and key authentication. Unlike conventional mechanical locks or pattern-based lug nuts, which are vulnerable to bypassing techniques, this integrated system offers robust, real-time protection through sensor fusion and ECU communication. The proposed solution minimizes false alarms, improves theft deterrence, and reduces economic losses associated with wheel theft.
