Vehicle security system with multi-vehicle compatible interface module for door locks and associated methods
First Claim
1. A vehicle security system for a vehicle comprising a door lock circuit including at least one door lock switch and at least one door lock controller responsive thereto, the vehicle security system comprising:
- a security controller for selectively operating the at least one door lock controller; and
a multi-vehicle compatible interface module for interfacing said security controller to the door lock circuit of a given vehicle from among a plurality of different vehicles including at least one vehicle wherein the door lock circuit comprises a single-wire door lock circuit including a lock resistance and an unlock resistance to be selectively connected in series with a voltage reference to thereby operate the at least one door lock controller, said multi-vehicle compatible interface module comprising a circuit board, a first variable resistor carried by said circuit board and being settable to match the lock resistance of the at least one door lock switch, and a second variable resistor carried by said circuit board and being settable to match the unlock resistance of the door lock switch.

Abstract
A vehicle security system is for a vehicle having a door lock circuit including a door lock switch, and a door lock controller responsive to the door lock switch. The security system includes a security controller for operating the door lock controller, and a multi-vehicle compatible interface module for interfacing to the door lock circuit of a given vehicle from among a plurality of different vehicles. In particular, the vehicle may include a single-wire door lock circuit having at least one of a lock resistance and an unlock resistance associated with a door switch. The multi-vehicle compatible interface module may include a circuit board carrying at least one variable resistor that is settable to match the lock/unlock resistance and thereby permit the security controller to operate the door lock controller.
