Vehicular security system with remote signalling for auto carjacking functions
First Claim
1. A vehicular security system-for recovery of a vehicle from an unauthorized person who has obtained possession of the vehicle by removing an authorized operator from the vehicle, the security system comprising a supervisory control unit carried within the vehicle, a remote signalling unit, the remote signalling unit being dimensioned so as to be and being inconspicuously carried by the authorized operator, the remote signalling unit and the supervisory control unit having means for effecting wireless communication therebetween, the vehicle having power door locks including a locking mechanism associated with each door and a control switch connected to each door locking mechanism, whereby each door locking mechanism is actuatable from a door unlocked positioned to a door locked position and from a door locked position to a door unlocked position responsive to actuation of the control switch, the vehicle having power windows including at least one power window motor operably connected to a movable window and at least one window control switch connected to each power window motor, whereby each movable window operably connected to a power window motor is actuated from a window open position to a window closed position or positions therebetween and from a window closed position to a window open position or positions therebetween in response to actuation of the window control switch, the security system further including power door lock interface means in communication with the supervisory control unit, the power door lock interface means for interrupting ,the connection between the power door lock control switch and each door locking mechanism, the power door lock interface means including means for actuating all power door locking mechanisms to the door locked position, the security system further including power window interface means in communication with the supervisory control unit, the power window interface means for interrupting the connection between each window control switch and its associated power window motor, the power window interface means including means for actuating the power window motor to move its associated operably connected window to the window closed position, the supervisory control unit being programmed to actuate the power window interface and the power door lock interface in response to wireless communication signalling between the supervisory control unit and the remote signalling unit after the authorized operator carrying the remote signalling unit has been removed from the vehicle.

Abstract
A vehicular security system includes an electronic supervisory control unit which communicates with a remote signalling unit to provide both conventional alarm system functions typically associated with securing an unoccupied vehicle as well as anti-carjacking functions. The anti-carjacking functions may be remotely initiated by the vehicle operator who has been forcibly removed from the vehicle or passively initiated and include locking the vehicle doors, closing the vehicle windows, and thereafter disabling the engine to confine a criminal carjacking perpetrator within the vehicle to wait apprehension by law enforcement authorities.

- 8. A vehicular security system for recovery of a vehicle from an unauthorized person who has obtained possession of the vehicle by removing an authorized operator from the vehicle, the security system comprising a supervisory control unit carried within the vehicle, a remote signalling unit, the remote signalling unit being dimensioned so as to be inconspicuously carried by the authorized operator, the remote signalling unit and the supervisory control unit having means for effecting wireless communication therebetween, the vehicle having power door locks including door locking mechanisms and windows connected to window motors, the power door locks and the window motors being controlled by a processor, the vehicular security system including a programmable gate array in communication with the supervisory control unit interfaced between the processor and the door locking mechanisms and interfaced between the processor and the window motors, the programmable gate array including means for interrupting processor control over the door locking mechanisms and the window motors and means for actuating the door locking mechanisms to a locked position and for actuating the window motors to close all windows in response to wireless communication signalling between the supervisory control unit and the remote signalling unit after the authorized operator carrying the remote signalling unit has been removed from the vehicle.

10. A method of recovering a vehicle from an unauthorized person who has obtained possession of the vehicle by removing, from the vehicle, an authorized operator, the method comprising the steps of:
-
(a) detecting an alarm condition indicating that the authorized operator is no longer in the vehicle by monitoring the status of wireless communication signals transmitted by a remote signalling unit in the possession of the authorized operator; (b) preventing the unauthorized person from exiting the vehicle through vehicle doors by locking all vehicle doors and disabling all door unlocking controls; (c) preventing the unauthorized person from exiting the vehicle through any windows by closing all open windows and disabling all window opening controls; and (d) disabling the vehicle from operating. - View Dependent Claims (11, 12)
