    摘要： A construction machine or industrial vehicle having a power supply system which includes a chargeable and dischargeable capacitor and a feeder circuit connecting a battery and the capacitor to a load capable of power running and regeneration. The capacitor is connected through a DC/DC converter which includes a controller that controls energy charged or discharged by the capacitor through the DC/DC converter to the load. The controller includes a power running/regeneration operation estimater which estimates an operation pattern including a point of change between power running and regeneration modes of the motor, or DC current supplied to an inverter, or control lever information and previously stored operation pattern information, and a capacitor target voltage calculator which controls an output command value of the DC/DC converter according to the estimated operation pattern so that a capacitor target voltage sequentially decreases in power running and sequentially increases in regeneration.

    摘要： The present invention provides a motor controller capable of selecting a motor drive system that provides the best possible system efficiency, according to monitored parameters indicative of the vehicle condition and the conditions of the mounted components. A drive signal processing block of the motor controller outputs drive signals to the motor by using a first drive system and a second drive system causing less switching loss than the first drive system, depending on a demanded torque for the motor. A drive system determination block, when an operating point of the motor allows selection between the first drive system and the second drive system, performs switching from the first drive system to the second drive system, based on the condition of an electric component of the vehicle or the vehicle running condition.
