  • Publication number: 20170058490
    Abstract: A working vehicle is provided with a hydraulic pump is driven using an engine. A hydraulic actuator is driven using hydraulic fluid which is discharged from the hydraulic pump. A power generator motor driven using the engine. An electric actuator is driven using electrical power which is generated using the power generator motor. An exhaust processing apparatus cleans exhaust from the engine. A reducing agent tank retains reducing agent which is supplied to the exhaust processing apparatus. A retention amount detecting section detects the retention amount of the reducing agent inside the reducing agent tank. An engine control section performs output restriction control where the output of the engine is reduced when the retention amount is equal to or less than a first threshold. The electric actuator control section restricts the output of the electric actuator during executing of the output restriction control.

  • 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.
