LEARN MODE FOR REMOTE TRANSMITTERS

摘要

A remotely controllable vehicle system as shown in Fig. 2 for generating a response to an incoming threat to a secured area and/or control of user selectable convenience features, comprising a wireless transmitter (1) having at least one switch (3) for generating and transmitting a signal encoded with a data code word having at least one identification code word; a receiver (19) for receiving the signal; a decoder (23) for decoding the coded data word from the signal; a controller (23) responsive to a command data word embedded in the coded data word only if an identification code word embedded in the data code word is identical to at least one authorized identification code word stored in a memory (21) accessible to the controller; a learn mode as shown in Fig. 3 for programming a new identification code word of a new transmitter in the memory as the authorized identification code word only if multiple groups of the coded data words are transmitted from the transmitter and received by the controller.
