Abstract: A calculation apparatus includes a control unit configured to calculate a necessary distance that is necessary for a vehicle to perform lane change from a first travel lane to a second travel lane by combining a first distance that the vehicle travels while the vehicle waits to start the lane change, a second distance that the vehicle travels while a speed of the vehicle is adjusted, and a third distance that the vehicle travels while executing the lane change.

Abstract: A load sensing valve maintains a differential pressure at a set pressure by controlling a regulator in accordance with a differential pressure between a discharge pressure of a hydraulic pump and a load pressure of hydraulic actuators. A set pressure control device controls the set pressure. A controller controls the set pressure control device to reduce the set pressure more than when the work implement is being operated, when a predetermined determination condition that includes the work implement not being operated is satisfied.

Abstract: A user is notified of a recommendation lane as appropriate. A navigation system includes one or more processors, and one or more storage devices storing programs to be executed by the one or more processors. The one or more processors decide a lane change plan creation zone including a main lane group including a plurality of main lanes that is parallel to each other in a route between a place of departure and a destination, and a recommendation degree of each of a plurality of lane links included in the main lane group. The one or more processors generate a lane change plan on the basis of the lane change plan creation zone and the recommendation degree.

Abstract: To make it possible to accurately inform a user of a road that has become usable. A navigation device 1 includes a storing unit 10 that stores information concerning a map including unopened roads, a processing unit 12 that performs display of the map or a search for a route or the display of the map and the search for a route on the basis of the information concerning the map stored by the storing unit 10, and an acquiring unit 11 that acquires an opening situation of a road. The storing unit 10 stores, separately from the information concerning the map, the opening situation of the road acquired by the acquiring unit 11. The processing unit 12 performs the display of the map or the search for a route or the display of the map and the search for a route on the basis of the information stored by the storing unit.
