1. A hybrid system mounted on an industrial machine, the hybrid system comprising:
a rotation sensor which detects a rotation number of an engine;
at least either one of an accelerator sensor which detects an operation amount of an accelerator pedal and a rotation-number instruction unit which transmits a rotation-number signal instructing a certain rotation number to the engine; and
a control unit which controls an operation of the engine, wherein
the control unit executes control of calculating a torque determining factor for determining a system required torque as the hybrid system on the basis of at least either one of the operation amount of the accelerator pedal and the rotation-number signal transmitted by the rotation-number instruction unit, and control of calculating the system required torque on the basis of the rotation number detected by the rotation sensor and the calculated torque determining factor.
