Abstract: It is determined that assisting is required when a deviation of a target matching engine speed and a current engine speed is equal to or more than a predetermined value, and for a predetermined period of time since the time point at which it is determined that assisting is required, a target assist engine speed is set at a high rotation target matching engine speed which is more than the target matching engine speed, and thereafter the target assist engine speed is set gradually closer to the target matching engine speed, and an assist torque command value is output to the generator assisting output of the engine, and the engine speed is controlled, so that the engine speed attains the target assist engine speed.

Abstract: The disclosed rotating parking brake control device obviates the need for an operator to operate an emergency-stop switch. A hybrid controller, to which a brake is connected, outputs a drive control signal to a rotating electric motor to control drive of an upper rotating body and also controls the brake by generating a brake release command signal and outputting the brake release command signal to the brake. A pump controller also generates a brake release command signal, and the brake release command signal generated by the pump controller is transmitted to the hybrid controller through an inter-controller signal line. The brake release command signal is outputted to the brake only when the brake release command signal is generated by the hybrid controller and the brake release command signal is transmitted from the pump controller through the inter-controller signal line.
