A control system and method for controlling a vehicle system, such as an engine, is taught. The controller uses the angular position of a rotating component, and in particular the angular phase of the rotating component to another rotating component, as an input. The input is determined with high resolution, yet is determined in a computationally efficient manner to reduce the amount of computation which must be performed by the controller. By producing a high resolution result in a computationally efficient manner, the result can be available to the controller almost immediately after the measurement is taken and the cost of controller can be less than it otherwise would be. In some embodiments, the system and method can also accurately determine the static angular position of one or more rotating members. The system and method are believed to be particularly suitable for determine the angular phasor between one or more camshafts and the crankshaft of an engine.
