Method of monitoring conditions of vehicle tires and tires containing a monitoring device therein

摘要

A method for monitoring various physical conditions of pneumatic tires, and to a tire including a monitoring device. More particularly, the invention relates to a method of monitoring tires which uses an active, self-powered programmable electronic device which is installed in or on the interior surface of a pneumatic tire or on a tire rim. This device can be used for monitoring, storing and telemetering information such as temperature, pressure, tire rotations and/or other operating conditions of a pneumatic tire, along with tire identification information. The device can be activated by externally transmitted radio frequency waves and in response, the device compares or transmits information and provides a warning in the event a preselected limit is exceeded. $$
