Abstract
A vehicle power system includes an electric machine, an inverter electrically connected with the electric machine, and a controller. The controller, while injecting AC voltage output by the inverter into the electric machine as a DC voltage input to the inverter changes, drives a duty ratio of the inverter toward a constant value to obtain resolver offset information associated with the electric machine from a current response of the electric machine to the AC voltage.
