Apparatus and method for tire monitoring system
First Claim
1. A tire monitoring apparatus for a vehicle comprising:
- plural transmitting means respectively arranged in plural tires, each having a detecting means for detecting air pressure of the corresponding tire, and transmitting information including a detecting result by a radio wave;
plural receiving means arranged in the vehicle correspondingly to the respective plural transmitting means and receiving the information transmitted from the respective transmitting means, each of the receiving means having a signal receiving sensitivity changing means for changing signal receiving sensitivities; and
a control means for receiving the information from the receiving means and performing a control operation so as to display the detecting result included in the information at a display means,wherein each of the receiving means is arranged in such a manner that a distance between one receiving means and its corresponding transmitting means is made shorter than the other distances between the one receiving means and the other transmitting means,each of the receiving means is connected to the control means, so that each of the receiving means independently transmits the information to the control means when it receives the information contained in the radio wave, andthe control means controls the signal receiving sensitivity changing means such that each of the receiving means receives only the information included in the radio wave, which has a largest signal receiving level among the radio waves transmitted from the plural transmitting means.

Abstract
A tire monitoring apparatus for a vehicle has plural transmitters arranged in plural tires for detecting air pressure of the corresponding tire and transmitting information including a detecting result by a radio wave, plural receivers for receiving the information transmitted from the respective transmitters, and signal receiving sensitivity changing means for changing signal receiving sensitivities. In the apparatus, each of the receivers is arranged in such a manner that a distance between one receiver and its corresponding transmitter is made shorter than the other distances between the one receiver and the other transmitters. A control means controls the signal receiving sensitivity changing means such that each of the receivers receives only the information included in the radio wave, which has a largest signal receiving level among the radio waves transmitted from the plural transmitters.

-
plural transmitting means respectively arranged in plural tires, each having a detecting means for detecting air pressure of the corresponding tire, and transmitting information including a detecting result by a radio wave; plural receiving means arranged in the vehicle correspondingly to the respective plural transmitting means and receiving the information transmitted from the respective transmitting means, wherein each of the receiving means has a signal receiving sensitivity changing means for changing signal receiving sensitivities, and each of the receiving means is arranged in such a manner that a distance between one receiving means and its corresponding transmitting means is made shorter than the other distances between the one receiving means and the other transmitting means; and a control means for receiving the information from the receiving means and performing a control operation so as to display the detecting result included in the information at a display means, wherein a method of monitoring the conditions of the tires comprises the steps of; transmitting the information received by each of the receiving means to the control means, when each of the receiving means has received the information contained in the radio wave; and controlling, by the control means, the signal receiving sensitivity changing means such that each of the receiving means receives only the information included in the radio wave, which has a largest signal receiving level among the radio waves transmitted from the plural transmitting means. - View Dependent Claims (7, 8)
