Abstract: A method and associated system for monitoring the on-vehicle yaw-rate sensor includes determining a vehicle heading during vehicle operation and determining a first vehicle heading parameter based thereon. A second vehicle heading parameter is determined via the yaw-rate sensor. A yaw-rate sensor bias parameter is determined based upon the first vehicle heading parameter and the second vehicle heading parameter. A first yaw term is determined via the yaw-rate sensor, and a final yaw term is determined based upon the first yaw term and the yaw-rate sensor bias parameter.
