Abstract: A method for scaling a stability signal in a steering system is provided and includes computing, by a torque boost module, an assist torque command to cause a motor of the steering system to generate an assist torque. Further, the method includes computing, by a stability compensation module, a stabilized torque command based on an input signal, the stabilized torque command modifying the assist torque command. Further, the method includes computing, by a stability monitoring module, a stability scaling factor to adjust the stabilized torque command based on a duration and severity of an instability detected in the input signal.

Abstract: An embodiment of a method of controlling one or more components of a vehicle includes receiving a reference steering command and one or more measurement signals related to a steering system of a vehicle, and estimating, by a processing device, a state of the steering system based on the one or more measurement signals, the steering system including at least a handwheel and a steering motor. The method also includes determining a maximum state achievable by the steering system at one or more times subsequent to receiving the one or more measurement signals, and controlling, by a control module, the steering system based on the steering reference command and the maximum state.

Abstract: Technical solutions are described for a payload detection module that detects payload using one or more steering system control signals and generates an axle load factor. An example payload detection module includes a rack torque module to determine a rack torque, a reference model module to determine a reference rack torque for the steering system based on a load scale factor, and a load factor calculation module to compute the axle load factor based on a difference between the rack torque and the reference rack torque. Further, a blend factor module determines a load blend factor according to the axle load factor. Further yet, a signal combiner combines a blended nominal base assist and a blended highload base assist according to the load blend factor, the combination modifying a motor torque command, the motor torque command being sent to a motor to generate assist torque.

Abstract: Technical solutions are described for facilitating a steering system to determine a motor velocity estimate for a motor of the steering system. For example, the steering system may include a state observer module that computes a base motor velocity estimate of the motor based on a plant model of the steering system. The steering system may further include a delay compensation module that computes a delay compensated velocity estimate based on the base motor velocity estimate and an acceleration of the motor. The steering system may further include a standstill detection module that modifies the delay compensated velocity estimate in response to a handwheel of the steering system being in standstill mode.
