Vehicle wireless communication apparatus
A vehicle wireless communication apparatus, including: a first portable device; a second portable device; a first receiver; a second receiver; a control apparatus; an in-vehicle communication network; and a relay unit, wherein, on receiving first directive data transmitted from the first portable device, the first receiver transmits first identification data of the first portable device to the relay unit; on receiving second directive data transmitted from the second portable device, the second receiver transmits 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.
1. 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 predetermined operation of the first portable device 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 predetermined operation of the in-vehicle equipment associated with the first portable device;
a second portable device that wirelessly transmits unique second identification data at predetermined regular intervals or in accordance with either a predetermined operation of the second portable device or a receipt of a request signal transmitted from a vehicle, and is also capable of wirelessly transmitting second directive data for directing the predetermined piece of in-vehicle equipment to exercise a predetermined operation of the in-vehicle equipment associated with the second portable device;
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 the predetermined operation of the in-vehicle equipment associated with the first portable device and the predetermined operation of the in-vehicle equipment associated with the second portable device 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 selectively transmits more-recently received data among the first identification data and the second identification data to the control apparatus as identification data continuously at predetermined regular intervals.
2. The vehicle wireless communication apparatus according to claim 1 ,
wherein a plurality of the control apparatuses are connected to the in-vehicle communication network, and the control apparatuses start an operation based on the identification data at different timings.
3. The vehicle wireless communication apparatus according to claim 1 ,
wherein the control apparatus has a storage unit which stores information of a default-state in association with the first identification data and the second identification data, the default-state being a state of the various in-vehicle equipment at the time when the vehicle is actuated by a signal transmitted from the first portable device or the second portable device and the vehicle is still stationary.
