Abstract

The truck security system emits an audible alarm when a cargo door is open and a driver or other person working on the truck goes beyond a defined distance, generally the immediate vicinity, from the truck exposing cargo to possible theft. In a truck having more than one cargo door, an alarm is sounded if more than one door is open simultaneously. If an attempt is made to start the engine with a door open, the system sounds an alarm in the cab and ignition is prevented. The system includes sensing means to detect if cargo doors are opened or closed, control logic circuitry and a clock, a RF signal receiver, an ignition cut-off, an audible alarm and a battery to independently power the security system, all of which are situated on the truck.
