Vehicle wheel information obtaining apparatus and wheel information processing apparatus
First Claim
1. A vehicle wheel information obtaining apparatus for obtaining wheel information relating to a wheel of a vehicle, said apparatus comprising:
- a wheel state detector which is provided on the wheel and which detects a state of the wheel;
a transmitter which is provided on the wheel and which transmits a wheel data set, as said wheel information, containing a wheel state data representing the detected state of the wheel and a wheel identification data identifying the wheel;
a receiver which is provided on a body of the vehicle and which receives said wheel data set transmitted by said transmitter;
a data processor which processes said wheel data set received by said receiver, said data processor having an identification-data registering mode for registering said wheel identification data contained in said wheel data set, and a wheel-state data obtaining mode for obtaining said wheel state data contained in said wheel data set; and
a communication-intensity reducing device which reduces at least one of a transmission strength of said transmitter and a reception sensitivity of said receiver, such that said at least one of said transmission strength and said reception sensitivity is lower when said data processor is in said identification-data registering mode, than when said data processor is in said wheel-state data obtaining mode.

Abstract
A vehicle wheel information obtaining apparatus for obtaining wheel information relating to a wheel of a vehicle. The apparatus includes: (a) a wheel state detector which detects a state of the wheel; (b) a transmitter which is provided on the wheel and which transmits a wheel data set containing a wheel state data representing the detected state of the wheel and a wheel identification data identifying the wheel; (c) a receiver which is provided on a vehicle body and which receives the wheel data set transmitted by the transmitter; (d) a data processor which processes the wheel data set received by the receiver; and (e) a communication-intensity reducing device which reduces a transmission strength of the transmitter or/and a reception sensitivity of the receiver, such that the transmission strength or/and the reception sensitivity is lower when the data processor is in an identification-data registering mode, than when the data processor is in a wheel-state data obtaining mode.

8. A vehicle wheel information obtaining apparatus for obtaining wheel information relating to a wheel of a vehicle, said apparatus comprising:
-
a wheel state detector which is provided on the wheel and which detects a state of the wheel;
a transmitter which is provided on the wheel and which transmits a wheel data set, as said wheel information, containing a wheel state data representing the detected state of the wheel and a wheel identification data identifying the wheel;
a receiver which is provided on a body of the vehicle and which receives said wheel data set transmitted by said transmitter;
a data processor which processes said wheel data set received by said receiver, said data processor having an identification-data registering mode for registering said wheel identification data contained in said wheel data set, and a wheel-state data obtaining mode for obtaining said wheel state data contained in said wheel data set; and
a communication-intensity changing device which changes at least one of a transmission strength of said transmitter and a reception sensitivity of said receiver, such that said at least one of said transmission strength and said reception sensitivity varies depending upon whether said data processor is in said identification-data registering mode or in said wheel-state data obtaining mode.

9. A vehicle wheel information processing apparatus for processing wheel information relating to a wheel of a vehicle, said apparatus comprising:
-
a receiver which is provided on a body of the vehicle and which receives a wheel data set, as said wheel information, containing a wheel state data representing a state of the wheel and a wheel identification data identifying the wheel;
a data processor which processes said wheel data set received by said receiver, said data processor having an identification-data registering mode for registering said wheel identification data contained in said wheel data set, and a wheel-state data obtaining mode for obtaining said wheel state data contained in said wheel data set; and
a reception-sensitivity reducing device which reduces a reception sensitivity of said receiver, such that said reception sensitivity is lower when said data processor is in said identification-data registering mode, than when said data processor is in said wheel-state data obtaining mode.
