1. A vehicle wheel information processing device comprising:
- a plurality of vehicle wheel communication devices which are provided at a single vehicle wheel and which are not connected to each other; and
a vehicle body communication device that communicates wirelessly with the plurality of vehicle wheel communication devices, wherein a transmission pattern of a signal transmitted from each of the vehicle wheel communication devices is set to be different to the transmission pattern of each other signal in such a manner that the signals of two or more vehicle wheel communication devices do not overlap each other, when requested at the same time.

Abstract
A vehicle body communication device (200) transmits a request signal to both a wheel side sensor (31) that is provided in a valve (24) of a wheel (22), and a tire side sensor (32) that is embedded in a tire tread (28). When the wheel side sensor (31) and the tire side sensor (32) receive the request signal from the vehicle body communication device (200), respective return signals are transmitted to the vehicle body communication device (200). The respective transmission patterns are set to be different.

22. A vehicle wheel information processing method for receiving and processing vehicle wheel information from a plurality of vehicle wheel communication devices provided at a single wheel and not connected to each other, the method comprising:
-
a first step in which respective signals of each of the vehicle wheel communication devices are wirelessly transmitted to a vehicle body communication device using a transmission pattern that is different for each vehicle wheel communication device in such a manner that the signals of two or more vehicle wheel communication devices do not overlap each other, when requested at the same time; and
a second step in which the respective signals wirelessly transmitted from each vehicle wheel communication device are received by the vehicle body communication device. - View Dependent Claims (23, 24)
