Abstract: Provided is a work machine including a controller configured to perform area restriction control for preventing a vehicle body from deviating from a work area set in a construction area. In this work machine, it is possible to easily set an area for which operation of the work machine is to be restricted in an actual space to a desired position, and to avoid displacement of the area for which the work machine is to be actually controlled from the set area. The work machine includes a controller configured to perform area restriction control for restricting operation of a vehicle body so as to prevent the vehicle body from deviating from a work area set in a construction area. The controller sets at least a part of the work area based on design data representing a final intended shape of a construction target in the construction area.

Abstract: Provided is a work machine including a front work device, the work machine including a state amount sensor that senses a state amount relating to an action state of the work device and a controller that controls an action of the work machine on the basis of an operation signal transmitted from a remote device by radio communication. The controller assesses a communication status of the radio communication, and, when restricting the action of the work machine on the basis of a result of the assessment, eases the restriction on the action of the work machine, depending on a sensing result from the state amount sensor. As a result, it is possible to appropriately restrict action on the basis of a communication status, while suppressing worsening of workability.

Abstract: In the invention, in automatic parking, a route from a parking start position to a target parking position is calculated prior to the start of parking. However, there are cases where an external environment recognition device cannot detect an obstacle at a distant or blind spot. In such a case, smooth parking is hindered when the vehicle is actually automatically parked. In the invention, in Step S1101, the vehicle is virtually moved from a parking start position 1201 in the direction of a turning position, and a turning position 1206 is calculated on a parking route 1205. In Step S1103, a preliminary route to a target parking position 1207 when the vehicle is turned back at the turning position 1206 is calculated. In the next Step S1104, it is determined whether the preliminary route can be generated, and when the preliminary route satisfies a predetermined condition, the route calculated by a candidate route calculation unit 501 is adopted as an automatic parking route.

Abstract: Unfortunately, even when a new area, which cannot be recognized from the parking start position, is detected in the surrounding area as the vehicle travels on the parking route, the new area cannot be used effectively as the parking route. In step S304, when there is an area for extending the parking route in the newly detected area, the route is determined to be extensible. In step S305, it is determined whether the vehicle can be parked with one turnabout without extending the route, and when it is determined that the vehicle cannot be parked with one turnabout, the process proceeds to step S307 to perform the route extension process. When the posture of the vehicle at the turning point does not exceed a predetermined value in step S306, the process also proceeds to step S307.

Abstract: A steering angular acceleration becomes steep in a transition curve section, and sudden control is required for steering follow-up control, so that there is a problem that a steering wheel behavior at the time of steering control is suddenly changed. In the straight section 710a, the steering angle does not change and remains at zero. In a transition curve section 711a (steering angle increasing section), the steering angle is corrected to a section 702 where the steering angle exceeds a target steering angle after a section 701 where the steering angle is below the target steering angle. In the arc section 712, the steering angle maintains a constant angle. In a transition curve section 711b (steering angle decreasing section), the steering angle is corrected to a section 704 where a steering angle is below a target steering angle after a section 703 where the steering angle exceeds the target steering angle. In the straight section 710b, the steering angle does not change and remains at zero.
