Abstract: A method for controlling motion of a heavy-duty vehicle includes estimating a current vehicle state comprising at least velocity and acceleration, wherein the estimated current state is associated with a current state uncertainty, estimating a future vehicle state based on the current vehicle state, and on a predictive motion model of the vehicle, wherein the future vehicle state is associated with a future vehicle state uncertainty, defining a vehicle control envelope representing an operational limit of the vehicle, wherein the vehicle control envelope defines a range of vehicle states, comparing the estimated future vehicle state, and the associated future vehicle state uncertainty, to the vehicle control envelope, and, if a probability that the future vehicle state breaches the control envelope is above a configured threshold value, limiting a motion capability of the vehicle.

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).

Abstract: A system for estimating an articulation angle of a vehicle combination comprises a motion sensor for sensing one or more linear and/or angular motion quantities of the vehicle combination and a dynamics-based estimator configured to estimate state variables, including the articulation angle on the basis of the sensed motion quantities, wherein the dynamics-based estimator is dependent on one or more masses and moments of inertia of the vehicle combination.

Abstract: 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.

Abstract: A control arrangement for a vehicle motion system including a braking function, comprising motion actuators with one or more brake actuators pertaining to the braking function, a first vehicle motion management controller (VMM1) and a second vehicle motion management controller (VMM2), forming a redundant assembly to control the braking function, wherein, in riding conditions, the first vehicle motion management controller controls the brake actuators with a current nominal expected braking performance, while the second vehicle motion management controller (VMM2) is in a waiting-to-operate mode, the control arrangement comprising a hot swap functionality in which the second vehicle motion management controller (VMM2) is configured to take over control of the brake actuators from the first vehicle motion management controller, with the current nominal expected braking performance, in a short time period (SWT) less than one second, preferably less than 0.5 second, preferably less than 0.
