摘要:
To provide a hybrid type construction machine in which work can be kept on even if the amount of electricity stored in an electric storage device is out of an appropriate value. Both a hydraulic motor 27 and an electric motor 25 are provided for driving an upper swing structure 20. When the amount of electricity stored in a capacitor 24 is appropriate, the upper swing structure 20 is driven by both the hydraulic motor 27 and the electric motor 25. When the amount of electricity stored in the capacitor 24 exceeds an appropriate value, the mode is changed over to a mode in which the upper swing structure 20 is driven only by the hydraulic motor 27, and an assist electric generation motor 23 is assist-driven or engine-driven to thereby rapidly return the amount of electricity stored in the capacitor 24 to an appropriate range. The capacity of the capacitor 24 can be reduced, and the amount of electricity stored in the capacitor can be managed without losing the operability of swing motion.

The power-transmission device has an input shaft, an output shaft, a gear mechanism, and a motor. The gear mechanism includes a plurality of planetary gear mechanisms and a mode-switching mechanism, and transmits the rotations of the input shaft to the output shaft. The mode-switching mechanism selectively switches the drive-power transmission path of the power-transmission device between a plurality of modes. The motor is connected to the rotating elements of the planetary gear mechanisms. A target-input-torque determination unit determines the target input torque. The target input torque is a target value for the torque to be inputted to the power-transmission device. The target-output-torque determination unit determines the target output torque. The target output torque is a target value for the torque to be outputted from the power-transmission device. The command-torque determination unit uses the torque balance information to determine torque commands to the motor from the target input torque and the target output torque.

摘要:
A filter processor of a control apparatus for a rotary electric machine filters target torque for the rotary electric machine to suppress a vibrational frequency component of a drivetrain using a filter having a frequency transfer characteristic. A controller performs drive control of the rotary electric machine according to the filtered target torque. A parameter calculator calculates, according to a running condition of the vehicle, a parameter associated with a request value for responsivity of output torque of the rotary electric machine with respect to the target torque. A variable setter variably sets the frequency transfer characteristic of the filter to decrease a degree of attenuation of the vibrational frequency component with an increase of the request value for the responsivity of the output torque.
