Patent ID: 7663502

Claim:
An arrangement for wirelessly controlling systems in a vehicle, comprising; a movable device including a transmitter arranged to transmit different control signals based on user activation; at least one control unit arranged on or in connection with the vehicle, each of said at least one control unit including a receiver arranged to communicate with said transmitter and a processor coupled to said receiver and arranged to generate one of a plurality of different command signals based on control signals transmitted by said transmitter and received by said receiver; and a plurality of systems each arranged on or in connection with the vehicle, all of said systems being coupled to said at least one control unit, each of said systems being responsive to command signals generated by said processor to perform a function relating to or affecting the vehicle, each of said systems being controlled by said movable device by causing said transmitter of said movable device to transmit a specific control signal which, when received by said receiver, causes said processor to generate a unique command signal to which only said system is responsive, said transmitter being arranged to transmit the control signals to a transmission network coupled to the Internet, said movable device being programmable via the Internet to enable the transmission of the specific control signals by said transmitter to cause said processor to generate the unique command signals and provide for responses by said systems, wherein said movable device is arranged to receive and respond to the return signal sent by said at least one control unit by transmitting a follow-up message via said transmitter, said follow-up message being a message of a type which only said movable device is arranged to provide to thereby ensure secure communications between said movable device and said at least one control unit, said receiver being coupled to the Internet such that said transmitter and said receiver are coupled to one another via the Internet; said at least one control unit being arranged to send a return signal in response to reception of a signal by said receiver which was transmitted by said transmitter to thereby provide bi-directional signal transmission between said transmitter and said at least one control unit.
