An embodiment of a system for evaluating a torque sensor includes an input module configured to receive torque signals from a hand wheel torque sensor in a vehicle, and a sensor evaluation module configured to perform monitoring a condition affecting the hand wheel torque sensor, and determining whether the condition indicates a desired situation in which a probability of an input torque being applied to the hand wheel is below a selected threshold. The sensor evaluation module is also configured to perform, based on detecting the desired situation, automatically analyzing the torque signals received during a time duration of the desired situation to estimate one or more torque sensor error values, and outputting at least one of a corrected torque signal and the one or more error values to a torque command generation module, the torque command generation module configured to generate a torque command to an electric motor.
