Abstract: A power transmission device of a work vehicle has an input shaft, an output shaft, a gear mechanism, and an electric motor. The gear mechanism has a planetary gear mechanism and transmits the rotation of the input shaft to the output shaft. The electric motor is connected to a rotating element of the planetary gear mechanism. The power transmission device is configured to change the rotation speed ratio of the output shaft with respect to the input shaft by changing the rotation speed of the electric motor. A control unit has a target torque determination unit and a target torque correcting unit. The target torque determination unit determines a target torque of the electric motor. The target torque correcting unit corrects the target torque according to a correction torque based on a moment of inertia of the electric motor.

Abstract: A work vehicle includes a pump brake control determining unit determines that a pump brake control is to be executed for causing a braking force to be generated by using a load on a hydraulic pump during braking. A pump brake torque control unit increases a pump brake torque to correspond to the load on the hydraulic pump during the pump brake control.

Abstract: A vehicle recognition unit of an information presenting device specifies a position of each of a plurality of vehicles, based on images captured by a plurality of imaging devices installed at a construction site. A vehicle designating unit receives designation of a designated vehicle, among the plurality of specified vehicles. A display control unit outputs a signal for displaying in an overlapping manner a proximity plot representing a position of another vehicle whose distance from the designated vehicle is less than a threshold on an overhead image of the construction site.
