Abstract

An on-vehicle electronic device creates a first signal and a second signal, and designates the number of times of transmitting the second signal. When noise is generated, the first signal includes information indicating a period of time to receive a signal by the portable device longer than that when noise is not generated. When noise is generated, the number of times of transmitting the second signal to a portable device by the on-vehicle electronic device to be designated is larger than that when noise is not generated. For the period of time to receive a signal indicated by the first signal, the portable device receives a signal.
