Abstract: A steering assembly for a vehicle comprises first and second steering actuators, each configured to be actuated in accordance with at least one signal issued from a motion control system to control a steering angle of at least one steerable ground engaging member of the vehicle. The first and second steering actuators are associated with corresponding first and second nominal steering capabilities, each defining at least one limitation of at least one of the following: steering angle, steering angle rate and steering torque, for the at least one steerable ground engaging member. The motion control system is adapted to, upon detection of a malfunction associated with the first steering actuator, associate the second steering actuator with a second enhanced steering capability instead of the second nominal steering capability. The second enhanced steering capability is different from the second nominal steering capability.
