In an on-board communication system, an on-board device transmits processing start signals and detection signals from a plurality of antennas provided in a vehicle, and a portable device receives the processing start signals and the detection signals and transmits a response signal that includes information corresponding to the received detection signals. Position detection of the portable device is performed based on the response signal. The processing start signals start reception processing of the detection signals by the portable device. The detection signals are successively transmitted from the plurality of antennas, at a different timing for each of the plurality of antennas. Various vehicle processing, such as engine start processing, may be performed based on the detected position of the portable device, such as whether the portable device is inside or outside the vehicle.
