Abstract:
A control module for a vehicle includes a time recording module that stores timestamps that correspond to each of N teeth of a target wheel of the vehicle in memory. N is an integer. A position module generates M angular positions based on the timestamps. M is an integer greater than one. Each of the M angular positions corresponds to a space between adjacent ones of the N teeth. A position estimator determines position of the target wheel based on the M positions.
