Patent number: 7941257Abstract: A tire pressure monitoring system includes sensors respectively associated with tires normally installed on a vehicle. Each sensor transmits a sensor signal indicative of a parameter of the associated tire to a controller. The signal strength of each sensor signal as received by the controller varies over time when the tire is rolling and remains constant over time when the tire is stationary. The controller generates a received signal strength indicator (RSSI) signal indicative of the signal strength of each sensor signal as received by the controller. The controller processes the RSSI signals along with a speed signal indicative of whether the vehicle is moving or is stationary to determine if any tire is stationary while the vehicle is moving, and generates a warning indicative of an unmonitored tire installed on the vehicle in place of a tire upon determining that the tire is stationary while the vehicle is moving.Type: GrantFiled: October 30, 2007Date of Patent: May 10, 2011Assignee: Lear CorporationInventors: Kevin Cotton, Keith E.
