Communication system

A communication system comprising:

• a portable device provided with a communication function;
• a communication controller which automatically performs wireless communication with the portable device and controls a predetermined driver in accordance with whether wireless communication with the portable device is established;
• a selection device which selects one of a disablement mode, which disables automatic communication of the portable device with respect to the communication controller, and a communication mode, which enables automatic communication of the portable device;
• a determination unit which recognizes which one of the disablement mode and the communication mode the portable device is in to determine whether to enable or disable automatic communication with respect to the portable device in accordance with the recognition;
• and
• a recognition information providing device which provides the determination unit with recognition information used to recognize which one of the disablement mode and the communication mode the portable device is in, in accordance with the selection by the selection device;
• and
• an instruction device issues an instruction which instructs the portable device to issue a signal causing the communication controller to operate the predetermined driver when the portable device is in the disablement mode,
• wherein the communication controller includes the determination unit and stops outputting a signal when the determination unit determines that the portable device is in the disablement mode based on the recognition information provided from the recognition information providing device,
• wherein the portable device includes the selection device and the recognition information providing device,
• wherein the portable device includes a receiving circuit which receives a signal from the communication controller, the portable device inactivating the receiving circuit when the portable device is in the disablement mode,
• wherein the recognition information includes one of a communication mode signal, which indicates the communication mode, and a disablement mode signal, which indicates the disablement mode, and
• wherein the portable device transmits the signal to the communication controller by wireless communication based on the instruction from the instruction device without shifting from the disablement mode to the communication mode, and
• wherein the portable device includes a transmitting circuit which transmits a signal to the communication controller, the portable device inactivating the transmitting circuit when the portable device is in the disablement mode and activating the transmitting circuit in response to the instruction from the instruction device in the disablement mode,
• wherein the communication controller intermittently transmits a request signal, and the recognition information providing device of the portable device provides the determination unit with the disablement mode signal when the recognition information providing device receives disablement mode information generated by the selection device of the portable device and the receiving circuit receives the request signal from the communication controller in a predetermined range that is capable of wireless communication.
