WIPO Patent Application WO/2016/088547

A1

Provided are a vehicle-mounted communication system with which a vehicle-mounted machine is able to continue receiving a radio signal even if the signal is interrupted while the vehicle-mounted machine is receiving the radio signal from a portable machine, and the portable machine and vehicle-mounted machine which form said vehicle-mounted communication system. When an ID signal, indicating identification information (ID) corresponding to a vehicle, and more than M (where M is a natural number) data signals, indicating control content relating to a door lock function or a power window function, are caused to be included in a radio signal by the portable machine, and the portable machine transmits said radio signal, the portable machine adds the ID signal into the radio signal each time M (where M is 1 or 2, for example) data signals have been transmitted, and continues to transmit the radio signal. Meanwhile, each time the vehicle-mounted machine receives the ID signal included in the radio signal being received, the vehicle-mounted machine compares the identification information indicated by the received ID signal with identification information stored in a ROM, and continues to receive the radio signal having matching identification information.
