Abstract
Systems and methods for auto-location of tire pressure monitoring sensor units on a vehicle measure the angle of a wheel at two different times using a rim mounted or a tire mounted sensor and determines a difference in measured angles. The systems and methods provide for transmitting the angles and/or the difference in the measured angles along with a sensor identification to an electronic control module. Alternatively, the systems and methods provide for transmitting time differences to the electronic control module. The electronic control module correlates information transmitted from the wheel unit with antilock brake system data. A location of the wheel mounting the sensor is determined and the sensor identification is assigned.
