    Abstract: A server notifies a user of a vehicle that is able to participate in DR. The server includes a communication device and a processing device. The communication device communicates with a provider server that stores information indicating an execution period and an execution location of at least one job given by a provider. The processing device performs a process of inquiring the provider server about whether the at least one job includes a target job through the communication device. The target job is a job of which the execution period is included in a DR period and the execution location is in a vicinity area of a DR location. When the at least one job includes the target job, the processing device performs a notification process of notifying the user of target job information indicating the execution period and the execution location of the target job.

  • Patent number: 11661725
    Abstract: A loaded machine information acquisition unit acquires position information and azimuth direction information of a transport vehicle. An earth removal position-specifying unit specifies an earth removal position for loading a load target onto the transport vehicle, based on the position information and the azimuth direction information. A bucket position-specifying unit specifies a position of a bucket. An operation signal generation unit generates an operation signal for moving the bucket from the specified position to the earth removal position.

  • Patent number: 11619025
    Abstract: A control device outputs an operation signal of a work equipment and a swing body for moving a work equipment to a loading point when receiving a loading command signal. The control device does not output a dumping operation signal for causing the bucket to dump earth in a case where an azimuth direction in which the swing body faces is within a first region from a starting point azimuth direction to a predetermined reference azimuth direction, the starting point azimuth direction being an azimuth direction in which the swing body faces when the loading command signal is received. The control device outputs the dumping operation signal in a case where the azimuth direction is within a second region from the reference azimuth direction to an end point azimuth direction in which the swing body faces when the work equipment is positioned at the loading point.

  • Publication number: 20220251802
    Abstract: Occurrence of a skid due to revolution of a revolving unit is suppressed. A work machine includes a traveling unit, a revolving unit revolvably mounted on the traveling unit, and a controller that controls operations of the work machine. The controller determines whether or not a skid of the traveling unit has occurred in a revolving operation of the revolving unit during an automatic operation of the work machine. When the controller determines that the skid has occurred, it performs processing for weakening rotational inertial force generated in the revolving operation.

  • Patent number: 11401688
    Abstract: A control device of a loading machine includes an adjustment determination unit and an operation signal output unit. The loading machine includes a swing motor and a swing body. The adjustment determination unit determines whether or not an angle formed by an azimuth direction of a swing body when the swing body stops and a target stop azimuth direction is less than an allowable angle based on an azimuth direction, a swing speed, and the target stop azimuth direction of the swing body during braking of the swing motor. The operation signal output unit outputs a swing control signal for driving the swing motor in a case in which it is determined that the angle formed by the azimuth direction of the swing body when the swing body stops and the target stop azimuth direction is equal to or greater than the allowable angle.

  • Patent number: 11286638
    Abstract: An avoidance position specification unit specifies an interference avoidance position that is higher than a loading object and has no loading object therebelow. A timing determination unit determines a swing start timing based on a remaining swing angle formed by a straight line that extends from a center of swing to a work equipment and a straight line that extends from the center of swing to an interference avoidance position, and a height of the interference avoidance position. An operation signal output unit outputs an operation signal of the work equipment in a case of not reaching the swing start timing and outputs an operation signal for swinging a swing body at swing speed higher than that when not reaching the swing start timing and an operation signal of the work equipment, in a case of reaching the swing start timing.
