Abstract
An apparatus for sensing pressure in vehicle tires includes an interrogator () for providing a tire pressure interrogation signal, and a tire pressure monitor () for sensing pressure within a first tire () of the vehicle () and providing an actual tire pressure signal. A first wheel speed sensor () associated with the first tire () provides a reference wheel speed signal upon movement of the vehicle (). A second wheel speed sensor () associated with a second tire () of the vehicle () provides a wheel speed signal upon movement of the vehicle. A controller () activates the interrogator (), monitors the actual tire pressure signal, and correlates the reference wheel speed signal with the wheel speed signal from the second wheel speed sensor () for determining a tire pressure value of the second tire ().
