1. A system for remotely controlling the position of a land vehicle door which is capable of moving between a closed position in which the door covers a vehicle opening and an opened position in which the door uncovers the opening to provide access to the opening, the system comprising:

  • a mobile communication device supported on the vehicle for movement therewith and operative to produce an excitation signal in the form of a first electromagnetic field within a first range of the mobile device;

    a hand-held communication device operative to produce a response signal in the form of a second electromagnetic field when the hand-held device is located within the first range wherein the devices wirelessly communicate via inductive coupling, the mobile device being operative to remove identification data from the response signal, the identification data identifying the hand-held device; and

    control logic coupled to the devices, wherein the hand-held and mobile communication devices are capable of wirelessly transmitting and receiving, respectively, command signals as long as a pedestrian carrying the hand-held device is within a second range of the mobile device, the second range being greater than the first range, and the command signals contain the identification data and command data which identifies a pedestrian command for the vehicle to automatically perform an operation, the mobile device being operative to remove the identification data and command data from the command signals, the control logic being operative to determine if the hand-held device is an authorized hand-held device based on the identification data, the control logic being operative to detect when a pedestrian carrying an authorized hand-held device is located within the second range and to generate a door-opening command signal when the authorized device is located within the second range.
