ABSTRACT:
A vehicle communication path-tracing system (10) has a portable transmitter (12) and transceiver/controllers (14A–14N,14T), located separately from the transmitter (12). A transmitter/controller (14T) is located at a target vehicle (16T) and at least one other transceiver/controller (e.g.,14A) is located at an intermediate location. An intermediate transceiver/controller receives a command signal intended for the target vehicle and transmits a retransmitted command signal intended for the target vehicle. The target transceiver/controller receives the retransmitted command signal and transmits an acknowledgement signal, intended for reception by the at least one intermediate transceiver/controller that transmitted the retransmitted command signal received at the target vehicle. The at least one intermediate transceiver/controller receives an acknowledgement signal and transmits a retransmitted acknowledgement signal.
