This control method includes: activating the electric motor 41 by an activation operation; and regulating the activation of the electric motor 41 without depending on the activation operation when activation conditions are not satisfied. The activation conditions include a first condition related to the state of charge of the secondary battery 50.

[Problem] To provide a working machine in which an output section including an electric motor is disposed at a position farther away from a road surface. [Solution] A working machine 100 includes a traveling body 200 that can travel by a drive wheel 203. The drive wheel 203 is mounted on a side frame 2012. The side frame 2012 is connected to a lower side of a side portion of a center frame 2011. The working machine 100 includes an output section 1 and a transmission mechanism 3. The output section 1 is supported by the center frame 2011 and outputs a driving force of an electric motor 11. The transmission mechanism 3 transmits the driving force from the output section 1 to the drive wheel 203 side. The transmission mechanism 3 includes a transmission shaft portion 33. The transmission shaft portion 33 extends downward from the output section 1 side toward the drive wheel 203 side.

[Problem] There are provided a route generation method, a route generation program, and a route generation system that can easily generate a target route on which a work vehicle is caused to automatically travel in a non-rectangular work area.[Solution] In an automatic traveling system 1, a generation processing unit 213 sets one of a first route generation mode of generating the target route based on a first reference line that serves as a reference at a time of generating the target route, and a second route generation mode of generating the target route based on the first reference line and a second reference line having a different shape or azimuth from a shape or an azimuth of the first reference line.

[Problem] Provided are a power supply control method, a power supply control program, and a power supply control system capable of retaining information regarding automatic traveling even in a case where a key of a work vehicle is temporarily switched to an OFF state. [Solution] A vehicle control device 11 includes a storage processing unit 112 that stores information regarding automatic traveling in a storage unit 115 by using power supplied from a battery 18 in a case where a key switch of a work vehicle 1 is in an ON state, and a retention processing unit 114 that continues supply of power to the storage unit 115 when predetermined conditions for starting automatic traveling are satisfied and stops the supply of power to the storage unit 115 when the predetermined conditions are not satisfied in a case where the key switch is switched to an OFF state.

[Problem] Provided is a technique capable of improving convenience of a work vehicle capable of setting a maximum vehicle speed and a maximum engine rotation speed. [Solution] An exemplary work vehicle is a work vehicle including a display device. The display device is provided to be capable of displaying a setting confirmation screen on which a maximum vehicle speed display area for displaying a set value of a maximum vehicle speed and a maximum engine rotation speed display area for displaying a set value of a maximum engine rotation speed are displayed side by side. The setting confirmation screen includes a maximum vehicle speed operation area that is displayed side by side with the maximum vehicle speed display area and enables a change of the set value of the maximum vehicle speed, and a maximum engine rotation speed operation area that is displayed side by side with the maximum engine rotation speed display area and enables a change of the set value of the maximum engine rotation speed.

[Problem] Provided is a technique capable of improving convenience of a work vehicle capable of using a plurality of travel drive modes.[Solution] An exemplary work vehicle is a work vehicle switchable between a plurality of travel drive modes and between a plurality of speed change states, and includes a display device that displays a setting screen for setting the travel drive mode. The travel drive mode can be set for each of the speed change states using the setting screen.

[Problem] To provide a path generation method, a path generation program, and a path generation system capable of correcting the position of a target path along which to cause a work vehicle to automatically travel in a field including a work area and a non-work area. [Solution] An automatic traveling system 100 includes a setting processing unit 211 that sets a work area in which to cause a work vehicle 10 to perform work while causing the work vehicle 10 to automatically travel, and a non-work area outside the work area, a generation processing unit 212 that generates a target path along which to cause the work vehicle 10 to automatically travel, and a correction processing unit 213 that corrects the position of the target path when a correction operation to correct the position of the target path is received.

[Problem] To provide a path generation method, a path generation program, and a path generation system capable of generating a target path based on a reference line in an appropriate position. [Solution] An automatic traveling system 100 includes a setting processing unit 211 that sets the shape of a field, a work area located inside the field, and a headland area located inside the field and outside the work area, and a generation processing unit 212 that generates a target path along which to cause a work vehicle 10 to automatically travel, based on a reference line generated according to a predetermined operation, and the work area.

[Problem] Provided are a path generation method, a path generation program, a path generation system, and an automatic travel method capable of improving work efficiency in a case where work paths are connected at an obtuse angle. [Solution] The path generation method includes generating a target path including a first work path and a second work path following the first work path and causing a work vehicle to automatically travel. The path generation method includes, in a case where an angle formed between the first work path and the second work path is larger than 90 degrees and smaller than 180 degrees, setting either one of a first mode for generating a target path including a backward path at a connection portion between the first work path and the second work path and a second mode for generating a target path not including the backward path at the connection portion.

To provide a technique that can continuously operate an inboard load and can prevent a marine vessel from moving due to an accidental operation while a helmsman is taking a rest. A control system is a control system of a marine vessel including a battery and an inboard load, and has a steering suspension mode that restricts steering of the marine vessel and supplies electric power from the battery to the inboard load.
