  • Working vehicle and working vehicle control method
    Patent number: 9540785
    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.
