Abstract
A system includes sensor modules, each associated with a wheel on a vehicle, and a receiver unit. Each sensor module calculates a rotation period associated with the wheel during turn mode vehicular motion and determines rotation direction of the associated wheel during straight vehicular motion. A data packet that includes a unique identifier for the sensor module, the rotation period, and the rotation direction are transmitted from each sensor module for receipt at the receiver unit. The receiver unit determines the steered wheels and non-steered wheels based on the rotation period, and the receiver unit can determine which wheels are on the right side or the left side of the vehicle based on the rotation direction. Knowledge of the steered and non-steered wheels and the rotation direction of the wheels, enables the receiver unit to assign locations of the sensor modules, and hence positions of the wheels of the vehicle.
