First Claim
1. A vehicular wireless transmission apparatus used by being installed in a host vehicle that belongs to a host vehicle model, the vehicular wireless transmission apparatus cooperating with a different apparatus that is provided in the host vehicle to be separated from the vehicular wireless transmission apparatus, the different apparatus containing a host vehicle model data indicating the host vehicle model of the host vehicle,the vehicular wireless transmission apparatus comprising:
- an antenna;
a wireless transmission portion which provides modulation and output power to a signal to transmit;
a coaxial cable that is included in a conductive line that connects the wireless transmission portion to the antenna;
an adjustment value storage portion that is rewritable, storing, before being installed in the host vehicle,(i) default vehicle model data that indicates a default vehicle model, as determined vehicle model data, and(ii) a default adjustment value that corresponds to the default vehicle model, as a determined adjustment value;
a table storage portion that stores, before being installed in the host vehicle,an adjustment value determination table that permits determining the determined adjustment value corresponding to each of a plurality of different vehicle models other than the default vehicle model, the adjustment value determination table being used when correcting the default adjustment value to be compliant with each of the plurality of different vehicle models;
an output adjustment section which provides an adjustment of the output power of the wireless transmission portion after being installed in the host vehicle based on the determined adjustment value so as to adjust an effective transmission power emitted from the antenna to a predetermined value; and
an adjustment value determination section thatreads, after being installed in the host vehicle, the host vehicle model data indicating the host vehicle model from the different apparatus and, then,performs a determination as to whether the host vehicle model data read from the different apparatus is identical to the determined vehicle model data stored in the adjustment value storage portion,whereinwhen the performed determination is affirmed, the adjustment value determination section maintains the determined adjustment value, which was stored in the adjustment value storage portion before the vehicular wireless transmission apparatus is installed in the host vehicle, to be unchanged;
when the performed determination is negated, the adjustment value determination sectiondetermines a corrected adjustment value corresponding to the host vehicle model data read from the different apparatus based on the adjustment value determination table, which has stored in the table storage portion before the vehicular wireless transmission apparatus is installed in the host vehicle,stores, as the determined adjustment value, the corrected adjustment value in the adjustment value storage portion, andwrites, as the determined vehicle model data, the host vehicle model data read from the different apparatus over in the adjustment value storage portion; and
the output adjustment section provides the adjustment of the output power of the wireless transmission portion, after being installed in the host vehicle, based on the determined adjustment value that is presently stored in the adjustment value storage portion and corresponding to the host vehicle model data read from the different apparatus.

Abstract
A vehicular wireless transmission apparatus includes a memory that stores (i) a default adjustment value relative to a default vehicle model, (ii) a default vehicle model data indicating the default vehicle model, and (iii) a correction value table for correcting the default adjustment value to be compliant with each of different vehicle models different from the default vehicle model. When a host vehicle model data read from a different ECU does not match with the default vehicle model data stored in the memory, it is determined that the vehicular wireless transmission apparatus is presently mounted in a host vehicle model indicated by the host vehicle model data read from the different ECU. The default adjustment value is then corrected by retrieving a correction value corresponding to the host vehicle model data from the correction value table.

1. A vehicular wireless transmission apparatus used by being installed in a host vehicle that belongs to a host vehicle model, the vehicular wireless transmission apparatus cooperating with a different apparatus that is provided in the host vehicle to be separated from the vehicular wireless transmission apparatus, the different apparatus containing a host vehicle model data indicating the host vehicle model of the host vehicle,
the vehicular wireless transmission apparatus comprising: -
an antenna; a wireless transmission portion which provides modulation and output power to a signal to transmit; a coaxial cable that is included in a conductive line that connects the wireless transmission portion to the antenna; an adjustment value storage portion that is rewritable, storing, before being installed in the host vehicle, (i) default vehicle model data that indicates a default vehicle model, as determined vehicle model data, and (ii) a default adjustment value that corresponds to the default vehicle model, as a determined adjustment value; a table storage portion that stores, before being installed in the host vehicle, an adjustment value determination table that permits determining the determined adjustment value corresponding to each of a plurality of different vehicle models other than the default vehicle model, the adjustment value determination table being used when correcting the default adjustment value to be compliant with each of the plurality of different vehicle models; an output adjustment section which provides an adjustment of the output power of the wireless transmission portion after being installed in the host vehicle based on the determined adjustment value so as to adjust an effective transmission power emitted from the antenna to a predetermined value; and an adjustment value determination section that reads, after being installed in the host vehicle, the host vehicle model data indicating the host vehicle model from the different apparatus and, then, performs a determination as to whether the host vehicle model data read from the different apparatus is identical to the determined vehicle model data stored in the adjustment value storage portion, wherein when the performed determination is affirmed, the adjustment value determination section maintains the determined adjustment value, which was stored in the adjustment value storage portion before the vehicular wireless transmission apparatus is installed in the host vehicle, to be unchanged; when the performed determination is negated, the adjustment value determination section determines a corrected adjustment value corresponding to the host vehicle model data read from the different apparatus based on the adjustment value determination table, which has stored in the table storage portion before the vehicular wireless transmission apparatus is installed in the host vehicle, stores, as the determined adjustment value, the corrected adjustment value in the adjustment value storage portion, and writes, as the determined vehicle model data, the host vehicle model data read from the different apparatus over in the adjustment value storage portion; and the output adjustment section provides the adjustment of the output power of the wireless transmission portion, after being installed in the host vehicle, based on the determined adjustment value that is presently stored in the adjustment value storage portion and corresponding to the host vehicle model data read from the different apparatus. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)
