The present disclosure relates to method for controlling a driving operation of an autonomously controlled vehicle. In particular, a navigation system is controlled to autonomously operate the vehicle in a direction from a position of loss of location to a first upcoming stop position; and to controlling the vehicle to a stand-still operation when the vehicle arrives at the stop position for calibration of a sensor arranged to measure an angular velocity of the vehicle.

The invention relates to a method of reducing or preventing lateral oscillations of at least one connected vehicle unit of a vehicle combination, the method comprising providing one or more parameters associated with a setup of the vehicle combination; determining, based on the one or more parameters, one or more critical frequencies having critical rearward amplification of a motion variable between the leading vehicle unit and the at least one connected vehicle unit; monitoring a steering input to the leading vehicle unit; determining whether the steering input excites any of the one or more critical frequencies; and automatically triggering a countermeasure for reducing or preventing lateral oscillations of the at least one connected vehicle unit upon determining that the steering input excites any of the one or more critical frequencies.

Method of reducing or preventing lateral oscillations of connected vehicle unit, control system, steering system, leading vehicle unit, and vehicle combination

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.
