摘要:
In a vehicle control apparatus, a system controller that overall controls an engine controller and a converter controller is provided. The system controller drives, through the converter controller, a generator with a generator-rotational-speed command value ωc_ref1 smaller than idling maintenance minimum rotational speed ωe_idol_min of an engine, starts, through the engine controller, fuel injection to the engine after elapse of a predetermined time, and, when the rotational speed of the engine reaches a predetermined rotational speed threshold ωe_th that is larger than the generator-rotational-speed command value ωe_ref and smaller than the idling maintenance minimum rotational speed ωe_idol_min, outputs, to a converter, a gate cutoff signal GSTOP for turning off energization to the generator.

In a host controller included in a vehicle control apparatus, a generator-torque-command generating unit monitors an abnormal operation of the engine on the basis of an engine power generation command and a detection signal of a rotating speed detector, switches, when the abnormal operation of the engine is detected, a generator torque command to the lowest value of a torque command value for abnormal time set in advance as the generator torque command, thereafter, gradually increases the generator torque command, and, after recording, as a torque limit value, the magnitude of the generator torque command (a torque command value for abnormal time 3) at the time when the abnormal operation of the engine is detected again, switches the generator torque command to a torque command value for abnormal time (a torque command value for abnormal time 2) having a value smaller than the torque limit value.

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.

A propulsion control device of a hybrid vehicle that enables, during an operating state of a train, flexible control corresponding to the operating state includes a total control section that totally controls a power generating device, a power storage device, and a load device. The total control section monitors total generated power in all converters in a train formation and controls, on the basis of the total generated power and a fuel consumption characteristic of engines, speed we of the engines and generated power of the converters to further reduce a total fuel consumption in the formation.

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.
