US 2016/0090064 A1 · VEHICLE ALARM SYSTEM

Abstract

A vehicle alarm system 10 includes a control unit 12, a number of door contacts or switches 13, 14, 15 connected as inputs to the control unit 12, the switches including a spare wheel sensor 14 and a battery sensor 15, and a spare wheel locking mechanism 16 connected to the control unit 12 as an output amongst others. The locking mechanism 16 has an actuator in the form of an electric motor 36 which is configured slideably to displace a locking pin 37 between an open position and a closed position in which the pin 37 engages a spare wheel hoist 26 of the vehicle hence preventing unauthorised lowering/removal of the spare wheel. If the alarm is armed, the sensor 14 will detect when an attempt is made to loosen the wheel and in response thereto a siren 19 will be sounded and the locking mechanism 16 locked.
