Tire theft detection device and method of detecting tire theft
First Claim
1. A tire theft detection device comprising:
- a tilt angle sensor for detecting a tilt angle of a vehicle and outputting a tilt angle signal indicative of the tilt angle;
a chassis-side communication element disposed on a chassis of the vehicle, the chassis-side communication element communicating with a tire-side communication element responsive to the tilt angle signal output from the tilt angle sensor;
the tire-side communication element disposed on a tire of the vehicle, the tire-side communication element sending a reply signal in response to the communication from the chassis-side communication element; and
a controller for starting the communication between the tire-side communication element and the chassis-side communication element when the tilt angle signal is equal to or larger than a predetermined threshold, whereinthe controller determines that the tire is stolen when the chassis-side communication element is unable to receive the reply signal.

Abstract
A tilt angle sensor detects a tilt angle of a vehicle and outputs a tilt angle signal indicative of the tilt angle. A tire-side communication element is disposed on a tire of the vehicle, and sends a reply signal in response to the tilt angle signal. A chassis-side communication element communicates with the tire-side communication element. A controller starts a communication between the tire-side and the chassis-side communication elements when the tilt angle signal is equal to or larger than a predetermined threshold. The controller determines that the tire is stolen when the chassis-side communication element disables to receive the reply signal from the tire-side communication element.

9. A method of detecting a tire theft comprising:
-
detecting a tilt angle of a vehicle by a tilt angle sensor; outputting a tilt angle signal indicative of the tilt angle from a chassis-side communication element disposed on a chassis of the vehicle; sending a request signal from the chassis-side communication element to a tire-side communication element disposed on a tire of the vehicle to request a reply to the chassis-side communication element when the tilt angle signal is equal to or larger than a first predetermined threshold; and determining that the tire is stolen when the chassis-side communication is unable disables to receive a reply signal from the tire-side communication element. - View Dependent Claims (10)
