Patent Images
1. An apparatus for alarming of tire deflation, comprising:
- deflation detection means for detecting tire deflation;
vehicle speed detection means for detecting speed of a vehicle; and
alarm means for selecting an alarm level from a table of alarm levels having different magnitudes, said selected alarm level depending on a detected tire deflation and a detected vehicle speed, and providing an alarm having a magnitude proportional to said selected alarm level to include, under a constant level of deflation, a greater magnitude of alarm proportional to a greater magnitude of the detected vehicle speed.

Abstract
An apparatus for alarming of tire deflation is provided in which reliability of an alarm is raised by a manner of alarming slightly when tire deflation is small and detection accuracy of a deflation detection mechanism is small, while alarming largely when tire deflation is large and deflation is detected with large accuracy. The apparatus comprises deflation detection means for detecting tire deflation; vehicle speed detection means for detecting a speed of a vehicle; and alarm means for deciding an alarm level depending on a detected tire deflation and a detected vehicle speed, and providing an alarm at the decided alarm level.
