Abstract
A hybrid-type working machineincludes an engine; a supercharger; an electric generatorthat performs electricity generation by the driving force of the engineand assists the driving force of the enginethrough its own driving force; an inverter circuitA that is connected to an electric terminal of the electric generator; and a controllerwhich includes a nonvolatile memorythat stores first information indicating a correlation between the revolutions of the engine, the boost pressure of the superchargerand an output upper limit value of the engine, and drives the inverter circuitA. The controllercontrols the inverter circuitA so that the electric generatorassists the driving force when the required output exceeds the output upper limit value, based on a correlation stored in the nonvolatile memory
