    Abstract: A method for determining whether hands of an operator of a vehicle are positioned on a hand wheel of the vehicle is provided. The method generates a first frequency content below a first frequency from a hand wheel torque signal. The method generates a second frequency content above a second frequency from the first frequency content of the hand wheel torque signal. The method generates a hands on wheel (HOW) estimate signal based on the first frequency content and the second frequency content by determining a first contribution of the first frequency content to the HOW estimate signal, determining a second contribution of the second frequency content to the HOW estimate signal, and combining the first contribution and the second contribution to generate the HOW estimate signal. The method causes a system in a vehicle to operate based on the HOW estimate signal.

    Abstract: A method of controlling an electric power steering system of a vehicle is provided. The method determines that one or more hand wheel torque sensors of the vehicle are not enabled. The method generates an assist torque command by estimating a lateral acceleration of the vehicle based on a hand wheel angle and determining an amount of assist torque based on the estimated lateral acceleration. The method controls the electric power steering system using the generated assist torque command.

    Abstract: A method of controlling a power steering system of a vehicle is provided. The method determines a yaw rate of the vehicle. The method generates a hand wheel angle signal that indicates a position of a hand wheel of the vehicle based on the yaw rate. The method controls the power steering system by using the hand wheel angle signal.

    Abstract: A control system for a power steering system includes an error module that generates an error signal based on a difference of an estimated output vector and an output vector, a scaling module that calculates a feedback correction signal based on the error signal and an observer gain value, an extended state vector estimation module that determines an extended state vector estimate based on the feedback correction signal and a motor torque command, and a gain module that applies a gain to the extended state vector estimate to generate an estimated driver torque signal, the estimated driver torque signal is applied in control of the power steering system.

    Abstract: A method of controlling an electric power steering system of a vehicle is provided. The method estimates steering rack force to be caused by a tire of the vehicle and a surface of a ground with which the tire is in contact in response to determining that one or more hand wheel torque sensors of the vehicle are not enabled. The method generates a steering assist torque command based on the estimated steering rack force. The method controls the electric power steering system using the steering assist torque command.
