Title:
タイヤ盗難検出装置
Document Type and Number:
Japanese Patent JP4821714
Kind Code:
B2
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.
