Abstract
Technical solutions are described herein for steer-by-wire (SBW) steering systems to detect a rack-limiting condition and generate feedback signal that can provide responsive handwheel torque for a driver. According to one or more embodiments the steer-by-wire steering system includes a processor that receives input signals comprising a handwheel velocity signal and a vehicle speed signal. The processor determines a simulated left end stop position of a rack based on the input signals, and a simulated right end stop position of a rack based on the input signals. The processor compares a rack position with the simulated left end stop position and the simulated right end stop position. The processor generates a feedback signal based on a determination that the rack position is not within a range bound by the left end stop position and the right end stop position.
