Abstract: A limiting system for constraining a commanded steering angle for a vehicle including an electric power steering (EPS) system includes a controller in electronic communication with at least one other system of the vehicle. The controller executes instructions to receive a plurality of trajectory planning inputs that are each expressed as an array including a plurality of values, where the plurality of trajectory planning inputs includes a trajectory velocity array, a trajectory acceleration array, and a trajectory curvature array. The controller also executes instructions to determine a maximum rate of steering angle change based on the corresponding ideal rate of change of the commanded steering angle and the maximum rate change allowed by the EPS system.
