Abstract: Technical solutions are described for mitigating traction steer using an electric power steering system (EPS). A control system for a power steering system including a processor and memory are provided. The memory includes instructions that, when executed by the processor, cause the processor to generate a motor command as a function of a handwheel velocity, and to modify the motor command based upon a traction torque signal. A method for controlling a power steering system is also provided. The method includes generating a motor command as a function of a handwheel velocity; modifying the motor command based upon a traction torque signal; and applying the motor command to an actuator of the power steering system.

Abstract: A method for performing hysteresis shaping in a steer-by-wire (SbW) steering system of a vehicle includes determining a desired hysteresis associated with rotating a handwheel of the vehicle, determining, based on the desired hysteresis, whether to perform hysteresis subtraction or perform hysteresis addition, in response to a determination to perform hysteresis subtraction, calculating a hysteresis subtraction value, modifying an estimated rack load based on the hysteresis subtraction value, and generating a reference torque based on the estimated rack load as modified based on the hysteresis subtraction value, in response to a determination to perform hysteresis addition, calculating a hysteresis addition value and generating the reference torque based on hysteresis addition value, and controlling the handwheel based on the reference torque.

Abstract: A method for controlling a motor of a road wheel actuator (RWA) in a steer-by-wire (SbW) steering system of a vehicle includes providing a motor torque command signal to the motor, providing a dithering signal to the motor such that the dithering signal is applied to the motor torque command signal, the dithering signal being configured to allow road disturbances to cause movement of a rack bar of the SbW steering system, sensing the road disturbances, and generating an emulation signal based on the sensed road disturbances.

Abstract: A method for augmenting a return velocity of a handwheel coupled to a steering system of a vehicle includes calculating return-to-center (RtC) torque for the handwheel based on a vehicle speed and a position of the handwheel, calculating a return load value for the handwheel based on the RtC torque, providing the return load value as an input to an effort function of the steering system, and augmenting, based on the return load value and using the steering system, a return velocity of the handwheel.

Abstract: A method for rack force effort-based damping includes: receiving a handwheel velocity signal associated with rotational motion of a handwheel of a vehicle; determining a vehicle speed; identifying, in a rack force look-up table, a rack force value based on the handwheel velocity signal and the vehicle speed; generating a modified rack force signal by adding the rack force value to a rack force signal; identifying, in an effort look-up table, an effort value based on the modified rack force signal; and selectively controlling at least one aspect of a steering system based on the effort value.
