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.

Abstract: The invention relates to a method for predicting maintenance/replacement period for a component of a vehicle, the vehicle comprising a power-assisted steering system including a steering actuator (14) configured to assist in steering the vehicle at least as compensation for angular deviations of the road wheels (16) caused by road disturbances. The method comprises acquiring over time steering output data indicative of a magnitude and/or frequency of assisted steering as compensation for angular deviations of the road wheels (16) caused by road disturbances, comparing the acquired steering output data with stored component wear data, the stored component wear data being indicative of when maintenance/replacement of the component is due based on wear caused by road disturbances, and determining, based on the comparison of the acquired steering output data and the stored component wear data, whether or not maintenance/replacement of the component is due. The invention also relates to a system (10).

Abstract: 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.

Abstract: A method for controlling a vehicle brake system for a heavy duty vehicle including a primary brake system and an auxiliary brake system. The method includes configuring a wheel slip magnitude limit, obtaining a requested auxiliary brake torque, engaging the primary brake system at a torque determined in dependence of the requested auxiliary brake torque, while monitoring a wheel slip value, determining an allowable auxiliary brake torque in dependence of the requested auxiliary brake torque and the wheel slip value, and engaging the auxiliary brake system at the allowable auxiliary brake torque.
