Abstract: A central network processing unit and a computer implemented method for providing site-specific management information associated with a restricted access construction site to a first user device in a wireless communications network is provided. The first user device is associated with a first vehicle being at or on-route to enter the restricted access construction site. The method includes obtaining vehicle characteristic information from the first vehicle and/or the first user device. The method also comprises determining site-specific management information associated with the restricted access construction site based on the obtained vehicle characteristic information. The method further comprises providing the determined site-specific management information to the first user device.

Abstract: A hydraulic system for a working machine includes a first electric machine connected to a first hydraulic machine; a second electric machine connected to a second hydraulic machine, an output side of the second hydraulic machine being connected to an input side of the first hydraulic machine; at least one hydraulic consumer hydraulically coupled to an output side of the first hydraulic machine via a supply line and configured to be powered by the first hydraulic machine; and a valve arrangement arranged between the hydraulic consumer and the first and second hydraulic machines, wherein the valve arrangement is configured to control a return flow of hydraulic fluid from the hydraulic consumer to either the input side of the first hydraulic machine or an input side of the second hydraulic machine based on a requested output pressure from the first hydraulic machine.

Abstract: The invention relates to a method of controlling a working machine. The working machine comprises a first power source arranged to drive a mechanical driveline, a hydraulic system comprising a hydraulic pump and an actuator arranged to be driven to move by the hydraulic pump, where the hydraulic pump is separated from, or disconnectable from, the first power source. The method comprises determining whether the working machine is in an increased response mode. The method further comprises increasing a response of the hydraulic system upon determining that the working machine is in the increased response mode.
