Title: Vehicle remote control system having keyless entry and piggyback control features and associated methods

Abstract: A vehicle control system includes a data communications bus, a remote keyless entry (RKE) system, and a piggyback controller at the vehicle for performing a desired function based upon predetermined RKE signals generated on the data communications bus by the RKE controller. The RKE system may include an RKE transmitter to be carried by a user, an RKE receiver, and the RKE controller connected to the RKE receiver for generating the RKE signals on the data communications bus responsive to the RKE transmitter. An RKE actuator is connected to the bus for performing an RKE function. The piggyback controller permits the straightforward addition of one or more new remote control functions to a vehicle already including a remote keyless entry system and a data communications bus. The piggyback controller may comprise a piggyback alarm controller connected to at least one vehicle security sensor. The desired function may then be switching the piggyback alarm controller between an armed mode, capable of generating an alarm based upon the at least one vehicle security sensor, and a disarmed mode. In another advantageous embodiment of the invention, a remote start function can be piggybacked onto an existing RKE system.
