Method for controlling steering locking of a steer-by-wire steering system of a motor vehicle

Abstract

In a steer-by-wire steering system of a motor vehicle including a feedback actuator to simulate a steering feel to a steering device and including an electric motor with a motor shaft connected to a steering shaft to transmit a torque, and a steering lock including a latch connected to the steering shaft in a torsion-resistant manner and a lock to engage with the latch at locking positions to block a rotation of the steering shaft, a method for controlling steering locking of the steer-by-wire steering system includes, if an ignition is switched-off and a movement of the steering device is detected, determining a position of the steering shaft and a distance between the lock and a next locking position of the latch in a direction of the movement of the steering device, and if the distance is greater than a predefined value, transmitting a counter-torque to the steering shaft by the feedback-actuator in a direction opposite direction to the movement of the steering device until the locking position reaches the lock and the lock can engage with the latch.
