Anti-theft tire disabling device

摘要

A system for deflating a tire on a wheel of a vehicle upon theft of the vehicle, comprising a wheel mounted unit and at least one remote unit for deactivating the wheel mounted unit via remote signals. The wheel-mounted unit is automatically armed upon stopping of the vehicle and comprises a pressure release assembly mounted in an orifice of the wheel for deflating the tire, a sensor adapted to sense wheel rotation and wheel speed, and a controller connected to the sensor and pressure release assembly for activating the pressure release assembly in response to wheel rotation sensed by the sensor. There is a receiver for receiving incoming RF signals from the remote unit, and a power supply connected to the pressure release assembly, sensor, controller and receiver. Each wheel could have its own wheel-mounted unit. After deflation, the wheel-mounted units are automatically re-set.
