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 gear box for a working machine is arranged to be positioned in a first set of speed-changing gears and a second set of speed-changing gears. The gear box includes a gear box housing, an input shaft configured to receive torque, and an output shaft for supplying torque out, from the gear box, wherein the output shaft is connected to a planetary gear set of the gear box, a friction disc clutch arrangement which is arranged between a ring gear of the planetary gear set and the gear box housing for enabling connection of the ring gear to the gear box housing, and a control unit configured to controllably alternate the friction disc clutch arrangement between: an engaged state and an at least partially engaged state when the gear box is positioned in the first set of speed-changing gears, and between a disengaged state and an at least partially engaged state when the gear box is positioned in the second set of speed-changing gears. A corresponding method for controlling a gear box is also provided.

Abstract: A method of and a control unit arranged for controlling an internal combustion engine connected to a torque converter arranged to operate in a torque converter mode or a lock up mode are provided. The method includes determining whether the torque converter mode or the lock up mode is presently in operation and selecting to control an engine speed (N) in dependence of an operator input when the torque converter mode is present, and selecting to control an engine output power and/or engine output torque in dependence of operator input to the accelerator unit when the lock up mode is present.

Abstract: A method is provided for controlling a work machine during operation in a repeated work cycle including the steps of establishing a control strategy on the basis of at least one condition that varies in the course of the work cycle, and controlling at least one device in a work machine power transmission system in response to the established control strategy.

Abstract: A method is provided for controlling a vehicle, including receiving an operator input indicative of a desired power for at least one predetermined function, and variably controlling at least one pressure-actuated friction slip clutch in a vehicle powertrain in response to the received operator input in order to control a torque transmitted via the friction slip clutch.

Abstract: Method and arrangement for controlling movements of a work vehicle. The positional or geometric state of an equipment assembly for handling objects or material is determined and the control scheme which governs operation of at least one driveline component of the vehicle is varied depending on the determined equipment assembly state.

Abstract: A method for controlling the gears of a vehicle that has an automatic transmission that is arranged to change gear according to a plurality of gear modes that differ in that changing to a higher gear is carried out at different minimum engine speeds or, if the changing is carried out steplessly, with different degrees of gearing, with the transmission having a forward gear position for driving the vehicle forwards and a reverse gear position for driving the vehicle backwards, comprising detection of an operating parameter and, in response to this production of a parameter signal for a control unit, selection, that is carried out by the control unit, of one of the gear modes on the basis of the parameter signal's value. The parameter signal represents the total distance that the vehicle has been driven during an individual sequence with at least one of the forward gear position and the reverse gear position.
