Title:
HYBRID CONSTRUCTION MACHINE AND METHOD FOR MEASURING CAPACITANCE OF CAPACITOR OF HYBRID CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2011/145531
Kind Code:
A1
Abstract:
In order to enable more accurate measurement of the capacitance of an electric storage unit such as a capacitor, disclosed is a hybrid construction machine provided with a measurement unit (202) which measures the capacitance of a capacitor (22), and a monitoring unit (202) which monitors a first condition that an engine is being driven, a second condition that the adjustment value of a throttle dial (60) for adjusting the amount of fuel to be supplied to the engine is a maximum value, a third condition that a working machine and/or a slewing upper structure is being locked, and a fourth condition that the working mode is set to a power mode, and when all the first to fourth conditions are satisfied, transmits a control signal for starting the measurement of the capacitance of the capacitor (22) to the measurement unit (202). When all the conditions are not satisfied before the start of the measurement of the capacitance of the capacitor or during the measurement of the capacitance of the capacitor, a display control unit (203) performs a transition to a screen on which an unsatisfied condition is displayed to thereby suppress the start of the measurement and the continuation of the measurement.
