摘要： A hybrid-vehicle power generator control apparatus includes an integrated control unit that issues a driving command and a control command to an engine control unit and an electric-power conversion system control unit, respectively, based on requested electric power requested by a load apparatus, and a limiter that limits the control command from the integrated control unit such that when rotation frequency of an electric power generator is same as or lower than a predetermined value, the value of torque generated by the electric power generator becomes smaller than the value of torque generated by an engine. A limitation of the control command by the limiter prevents torques of the engine and the electric power generator from stepping out of the stable operating points.

摘要： Switches change the resistance value of a charge/discharge circuit in a period from starting a discharging at an upper limit voltage until the voltage reaches a lower limit voltage. An electric charge estimator computes electric charge by time-integrating current from a start of the discharging to an arbitrarily determined time, and computes a relationship between electric charge and voltage of a power storage device. An internal resistance estimator computes internal resistance based on voltages and currents of the storage device at times when resistance values are different. An electric energy estimator computes a relationship between electric charge and open voltage based on electric charge, voltage, current and internal resistance of the storage device. During charging or discharging of the storage device, the electric energy estimator estimates the electric energy of the power storage device based on the electric charge, the open voltage, the internal resistance, and the charge/discharge current.

摘要： A power-generation control unit controls the amount of power a generator can generate, when it is connected to an engine, by controlling a converter that converts AC power output by the generator to DC power. The power-generation control unit calculates a rotational-speed command value ωc_ref1 for the generator on the basis of a differential voltage value ΔVdc between a DC-voltage command value Vdc_ref for a power storage device and a DC voltage Vdc of a DC link portion; and executes a PWM control on an output of the converter on the basis of this rotational-speed command value ωc_ref1 such that the rotational speed ωc of the generator follows the rotational-speed command value ωc_ref1 and also such that the DC voltage Vdc follows the DC-voltage command value Vdc_ref so as to prevent overvoltage.
