Abstract
The disclosure relates to a method for operating a steering system of a vehicle having a front-axle steering assembly, a rear-axle steering assembly and a steering wheel. The method involves detecting a failure of the front-axle steering assembly, steering the vehicle exclusively via the rear-axle steering assembly based on a steering command issued by a driver via the steering wheel, comparing at least one detected physical value of the steering command with a limit value associated with the rear-axle steering assembly and, provided the at least one associated limit value is reached or exceeded by the at least one detected physical value of the steering command, applying a torque acting on the steering wheel via the electric motor coupled to the steering wheel, which torque counteracts the steering command.
