Vehicle wireless communication apparatus

A vehicle wireless communication apparatus, comprising:

• a first portable device that wirelessly transmits unique first identification data at predetermined regular intervals or in accordance with either a first predetermined operation or a receipt of a request signal transmitted from a vehicle and is also capable of wirelessly transmitting first directive data for directing a predetermined piece of in-vehicle equipment to exercise a second predetermined operation;
• a second portable device that wirelessly transmits unique second identification data at predetermined regular intervals or in accordance with either a first predetermined operation or a receipt of a request signal transmitted from a vehicle and is also capable of wirelessly transmitting second directive data for directing a predetermined piece of in-vehicle equipment to exercise a second predetermined operation;
• a first receiver capable of receiving data that is transmitted from the first portable device;
• a second receiver capable of receiving data that is transmitted from the second portable device;
• a control apparatus that performs a second predetermined operation based on the first identification data and the second identification data;
• an in-vehicle communication network that connects the first receiver and the second receiver to the control apparatus in a communicable manner;
• and
• a relay unit that is connected to the in-vehicle communication network, and that receives the first identification data and the second identification data transmitted respectively from the first portable device and the second portable device and transmits the first identification data and the second identification data to the control apparatus,
• wherein, on receiving the first directive data transmitted from the first portable device, the first receiver transmits the first identification data of the first portable device to the relay unit;
• on receiving the second directive data transmitted from the second portable device, the second receiver transmits the second identification data of the second portable device to the relay unit;
• and
• on receiving the first identification data transmitted from the first portable device or the second identification data transmitted from the second portable device, the relay unit transmits more-recently received data to the control apparatus as identification data continuously at predetermined regular intervals.
