Abstract

See full text

A construction machine comprises an electric motor/generator; an engine; an epicyclic gearing for rotating the electric motor/generator reversely when speed of a rotation output to a drive wheel is zero during running of the engine; a transmission configured to switch between a forward driving gear position and a backward driving gear position; and a controller for controlling the engine, the electric motor/generator and the transmission, based on at least an accelerator opening, and a state of charge in an electric storage device; the controller being configured to switch the forward driving gear position or the backward driving gear position to a direction opposite to a direction in which the construction machine is moving, and cause the electric motor/generator to generate reverse torque in a power running mode, when the electric storage device is in a fully charged state and the accelerator has been pressed down by a driver.
