Abstract

An embodiment of a system of a vehicle includes a power steering system that operates as commanded by control commands, and a control module configured to receive a first control command. The control module is also configured to generate a range signal indicative of a range of command values based on a plurality of input signals, generate a second control command based on a subset of the plurality of input signals, determine whether the first control command is out of the range for longer than a predetermined duration of time, and send the second control command to the power steering system in response to determining the first control command is out of the range for longer than the predetermined duration of time.
