Abstract: A display system includes a display and a controller. The controller causes the display to display a third figure representing a relative relationship between a first figure indicating a direction of a working implement of a working machine and a second figure indicating a direction of a target topography from the working machine.

Abstract: A first process acquires a true value of the position of a predetermined portion. A second process acquires a reference position of a work machine. A third process determines a plurality of correction candidate values of a parameter. The correction candidate values are used so that a calculation value of the position of the predetermined portion calculated based on the parameter from the reference position matches the true value. A fourth process calculates an assessment value indicative of the difference between the true value and a calculation value for each of plurality of correction candidate values. A fifth process determines a confirmation correction value of the parameter from among the plurality of correction candidate values based on the assessment value.

Abstract: A working vehicle includes a revolving pump output calculating section that calculates the revolving pump output where the output of an electric motor is converted to be the output of a hydraulic pump. A reduction amount determining section determines a reduction amount for the output of the hydraulic pump during the multiple operations based on the revolving pump output. A pump output determining section determines a value, where the reduction amount is subtracted from the output of the hydraulic pump which is determined according to the state with the multiple operations, in a first control mode as the output of the hydraulic pump during the multiple operations. The pump output determining section increases the output of the hydraulic pump during the multiple operations in a second control mode more than in the first control mode.

Abstract: A control system for a work vehicle includes a temperature detecting unit and a controller. The temperature detecting unit detects the temperature of the electrical drive system. The controller controls the output of an electric motor when the temperature of the electrical drive system detected by the temperature detecting unit exceeds a predetermined first threshold and an operating member of the movable body is positioned in a neutral position. The controller does not limit the output of the electric motor when the operating member for the movable body is being operated even when the temperature of the electrical drive system exceeds the first threshold.
