Tire Information Detecting Device
First Claim
1. A tire information detection device for use on a vehicle having wheels with tires, the device comprising:
- a housing fixed to a support member made of a conductive material and arrangeable on the vehicle;
a wheel velocity sensor, arranged in the housing, for detecting the rotation velocity of the wheel;
a receiver, arranged in the housing, for wirelessly receiving air pressure information of the tire; and
a controller for performing control in accordance with the detected rotation velocity and the air pressure information received by the receiver;
wherein the receiver includes a wireless frequency input terminal electrically connected to the support member.

Abstract
A tire information detection device including a housing fixed to a support member made of a conductive material and arranged on a vehicle is provided. A wheel velocity sensor for detecting the rotation velocity of a wheel and a receiver for wirelessly receiving air pressure information of a tire are arranged in the housing. A controller performs control in accordance with the detected rotation velocity and the air pressure information received by the receiver. The receiver includes a wireless frequency input terminal electrically connected to the support member. Therefore, the tire information detection device includes the receiver that stably receives information such as air pressure of the tire with a low cost while also being capable of processing vehicle velocity information.
