ABSTRACT:
A tire pressure control system for a vehicle having wheels with tires includes a controller and tire pressure sensors each having a transceiver. The sensors are within respective tires. Each sensor transmits information regarding the pressure of its tire to the controller. The controller transmits to the sensors a signal having markings based on rotation of a selected wheel. The signal as received by each sensor includes variations resulting from rotation of its associated wheel. The variations of the signal as received by the sensor corresponding to the selected wheel agree with the markings and the variations of the signal as received by each of the remaining sensors vary with the markings. Each sensor correlates the variations of the signal as received by the sensor with the markings. The sensor in which the variations of the signal agree with the markings transmits a confirmation regarding same to the controller.
