Title:

CONTROL DEVICE FOR CONSTRUCTION MACHINERY

Document Type and Number:

WIPO Patent Application WO/2017/154219

Kind Code:

A1

Abstract:

Provided is a control device for construction machinery that can maintain favorable operability for complex turning operations even when the power that can be supplied from an engine and the electrical power that can be supplied from an energy storage device fluctuate. A control device for construction machinery comprises: a front speed detector that detects the speed of a front drive unit; a turning body speed detector that detects the angular velocity of a turning body drive unit; a target trajectory calculation unit that calculates a target trajectory for a claw tip position of the front drive unit by incorporating the amount a front operation device is manipulated, the amount a turning operation device is manipulated, the speed of the front drive unit detected by the front speed detector, and the angular velocity of the turning body drive unit detected by the turning body speed detector; and an actuator power calculation unit that adjusts the power supplied to the front drive unit or the turning body drive unit so that the claw tip of the front drive unit follows the target trajectory calculated by the target trajectory calculation unit when the front operation device and the turning operation device are being simultaneously operated.
