Abstract

According to one or more embodiments, a steer by wire steering system includes a handwheel, and a handwheel actuator configured to secure a position of the handwheel. The securing includes determining a transition of the steer by wire steering system to an ingress/egress mode. The securing further includes, based on the determination that the steer by wire steering system is in the ingress/egress mode, computing a holding torque command based on a difference in a present angle of the handwheel and a target angle of the handwheel, which is caused by an input torque. Further, the securing includes generating a holding torque corresponding to the holding torque command to secure the position of the handwheel.
