Vehicle tire information obtaining apparatus and tire information processing apparatus

A vehicle tire information processing apparatus for processing tire information relating to a plurality of tires of a vehicle which include a mounted tire mounted on an axle of the vehicle and a non-mounted tire carried by the vehicle, said apparatus comprising:

• tire state detectors which are provided in the respective tires and each of which detects a state of a corresponding one of said tires;
• transmitters which are provided in the respective tires and which transmit tire data sets, as said tire information, each containing at least one tire-state data element representative of the detected state of a corresponding one of said tires;
• a receiver which is provided in a body of the vehicle and which receives said tire data sets transmitted by said transmitters;
• and
• a mounted-tire-state-data processor which processes the tire-state data element transmitted from said mounted tire, and which does not process the tire-state data element transmitted from said non-mounted tire.

• a receiver which is provided in a body of the vehicle and which receives said tire data sets transmitted by said transmitters;
• a non-mounted-tire information determining portion which determines whether each of said tire data sets received by said receiver has been transmitted from said non-mounted tire or not;
• and
• a data processor which processes said tire data sets in a predetermined first manner when one of said tire data sets can be determined to have been transmitted from said non-mounted tire, said data processor processing said tire data sets in a predetermined second manner different from said predetermined first manner when none of said tire data sets can be determined to have been transmitted from said non-mounted tire.

• a receiver which is provided in a body of the vehicle and which receives said tire data sets transmitted by said transmitters;
• and
• a pressure-data processor which processes an air pressure data included in said at least one tire-state data element,
• wherein said pressure-data processor includes:
• an air-pressure abnormality determining portion which effects a determination as to whether an air pressure of each of said tires is lower than a predetermined minimum value or not;
• and
• an informing device which informs a vehicle operator of a result of said determination in one of different manners that is selected depending upon whether said result of said determination relates to said mounted tire or said non-mounted tire.

• and
• a data processor which processes said tire data sets received by said receiver,
• wherein said data processor includes a data-processing restricting portion which restricts processing of one of said tire data sets that has been transmitted from said non-mounted tire.

• tire state detectors which are provided in the respective tires and each of which detects a state of a corresponding one of said tires;
• transmitters which are provided in the respective tires and which transmit tire data sets, as said tire information, each containing at least one quantitative data element representative of the detected state of a corresponding one of said tires;
• a receiver which is provided in a body of the vehicle and which receives said tire data sets transmitted by said transmitters;
• a tire information sorter which sorts said tire data sets received by said receiver, according to a threshold value, on the basis of said quantitative data element;
• and
• a threshold-value determining portion which determines said threshold value during running of the vehicle.
