Abstract
According to one or more embodiments of the present invention a steer by wire steering system includes a deviation detection unit configured to determine a deviation signal that is indicative of a disturbance in one or more components coupled to a rack. The steer by wire steering system further includes a handwheel notification module configured to generate a modification signal based on the deviation signal, in response to the deviation signal being detected for at least a predetermined duration. The steer by wire steering system further includes a handwheel control module that generates an input command corresponding to a reference torque generated by a road wheel actuator, a feedback torque for a driver is generated based on the input command. The handwheel control module further modifies the input command using the modification signal, the modification providing a notification corresponding to the disturbance to the driver.
