Abstract
A control system for an air maintenance tire system is provided. The control system includes a sensor unit that in turn includes a pressure sensor for measuring a pressure in the tire cavity and an antenna for transmitting pressure data. A processor receives the pressure data and includes a memory for storing a predetermined low-pressure threshold. Actuation means that are in communication with the processor and actuate and de-actuate operation of the air maintenance tire system. A first signal is transmitted from the processor to the actuation means to actuate operation of the air maintenance tire system when the measured pressure in the tire cavity is below the threshold. A second signal is transmitted from the processor to the actuation means to de-actuate operation of the air maintenance tire system when the measured pressure in the tire cavity is at or above the threshold.
