Abstract: The invention relates to a method of controlling a working machine. The method includes monitoring a detection region behind the working machine by means of a rear detection device; and determining whether the working machine is traveling forward or in reverse. The method further includes disregarding an object in the detection region detected by the rear detection device when the working machine is traveling forward. The invention also relates to a control system for controlling a working machine having a rear detection device arranged to monitor a detection region behind the working machine. The invention also relates to a working machine.

Abstract: A method is provided for controlling a gear shift from a forward gear to a reverse gear in a transmission arrangement, the method including the steps of: positioning a first locking mechanism and a first connecting mechanism at least in a partially engaged state for reducing a rotational speed of a planet carrier of a second planetary gear set; and positioning a second locking mechanism in an engaged state when a rotational speed of the planet carrier of the second planetary gear set is below a predetermined threshold limit.
