1. A vehicle-mounted communication device that is to be mounted on a vehicle, comprising:
a wireless communication unit that transmits an RF (Radio Frequency) signal that includes data, and is capable of changing a communication method;
an acquisition unit that acquires state information that indicates a state of the vehicle; and
a control unit that performs switching control to change the communication method based on the state information acquired by the acquisition unit,
wherein the wireless communication unit includes
an antenna, and
a wireless signal processing unit that generates an RF signal that conforms to the communication method and outputs the RF signal to the antenna, and is capable of changing the communication method, and
a filter that is connected between the wireless signal processing unit and the antenna, and
the wireless signal processing unit outputs a 1-bit digital signal to the filter as the RF signal,
wherein the wireless communication unit includes a plurality of filters,
the wireless signal processing unit is capable of superimposing RF signals that conform to a plurality of communication methods and outputting the RF signals from one port to the plurality of filters, and
through the switching control, the control unit is capable of switching between an option to select one communication method or an option to select a plurality of communication methods for the RF signals to be generated by the wireless signal processing unit.
