摘要： The invention relates to a steering assembly (12) for a vehicle (10). The steering assembly (12) comprises a first steering actuator (14) and a second steering actuator (16). The first steering actuator (14) is adapted to be actuated in accordance with at least one signal issued from a motion control system (18) to control a steering angle of at least one steerable ground engaging member (20, 22) of the vehicle (10) to thereby control the steering of the vehicle (10). The first steering actuator (14) is associated with a first nominal steering capability, 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 (20, 22). The second steering actuator (16) is adapted to be actuated in accordance with at least one signal issued from the motion control system (18) to control the steering angle of the at least one steerable ground engaging member (20, 22) of the vehicle (10) to thereby control the steering of the vehicle (10). The second steering actuator (16) is associated with a second nominal steering capability, 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 steerale ground engaging member (20, 22). The motion control system (18) is adapted to, upon detection of a malfunction associated with the first steering actuator (14), associate the second steering actuator (17) 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.

摘要： The present disclosure relates to a method for controlling steering of a vehicle arrangement. The method is controlling steering of the vehicle arrangement during a turning maneuver, by applying a differential wheel speed by at least one of individually controllable electric machines and reducing the operational capacity of a power steering system, when a first power utilization value, obtained by operating the individually controllable electric machines with the differential wheel speed, is equal to, or greater than a second power utilization value, obtained by operating the power steering system during the turning maneuver.
