Wireless communication system and communication method for wireless communication system

摘要

A mobile device includes a transmitting unit that, each time an ON operation of a switch in a first mode is performed, transmits a wireless signal corresponding to the first mode ON operation by changing a frequency band among three or more frequency bands and that, when an ON operation of the switch in a second mode is performed, transmits a wireless signal, corresponding to the second mode ON operation, in the frequency band selected at that time. The transmitting unit includes a frequency band computing unit that selects one of the three or more frequency bands through a computation for changing a communication environment when the second mode ON operation of the switch is repeatedly performed. A receiver of the in-vehicle device receives a wireless signal transmitted from the transmitting unit and recognizes command information allocated in advance in correspondence with each ON operation mode of the switch.

主权项

1. A wireless communication system comprising:
a transmitter configured to have a manually operable switch, each time an ON operation of the switch in a predetermined first mode is performed, to change a frequency band among a plurality of predetermined frequency bands to transmit a wireless signal corresponding to the ON operation in the first mode, and, when an ON operation of the switch in a second mode that is different from the first mode is performed, to transmit a wireless signal corresponding to the ON operation in the second mode in one of the frequency bands selected at that time; and a receiver configured to receive the transmitted wireless signal and to recognize command information allocated in advance in correspondence with each of the ON operations of the switch in the respective modes, the transmitter is configured to when the ON operation of the switch in the second mode is repeatedly performed, select one of the plurality of predetermined frequency bands through a computation for changing a communication environment, the number of the plurality of predetermined frequency bands being three or more, the transmitter, as the computation for changing the communication environment, being configured to learn whether there is a successful communication of a wireless signal based on the ON operation of the switch in the first or second mode for each of the plurality of frequency bands and then to select the frequency band that is determined to have a high communication success rate through the learning as the frequency band when the ON operation of the switch in the second mode is repeatedly performed, the transmitter including a storage device configured to accumulatively store the number of successful communications of a wireless signal based on the ON operation of the switch in the first or second mode for each of the plurality of frequency bands, and the transmitter, as the learning, and the transmitter is configured to obtain the frequency band having the largest number of successful communications accumulatively stored in the storage device and to select the obtained frequency band as the frequency band when the ON operation of the switch in the second mode is repeatedly performed.
