In a vehicle control apparatus, a host controller that collectively controls an engine controller and a converter is provided. In the host controller, an engine-power-generation-command generating unit and a generator-torque-command generating unit are provided. The 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 power-generation control unit 7 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 7 calculates a rotational-speed command value Éc_ref1 for the generator on the basis of a differential voltage value ”Vdc 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 Éc_ref1, such that the rotational speed Éc of the generator follows the rotational-speed command value Éc_ref1 and also such that the DC voltage Vdc follows the DC-voltage command value Vdc_ref so as to prevent overvoltage.

An object is to provide a magnetic-pole position detection apparatus for synchronous machines that allows a desired accuracy of magnetic-pole position detection regardless of variation in DC voltage of a DC voltage source. Calculation means (2a) changes a pulse width (tp) and a pulse-quiescent width (tn) in accordance with a DC voltage detection value (Vdc), using a pulse width determination section (22a), such that a desired accuracy of magnetic-pole position detection can be obtained regardless of variation in DC voltage of a DC voltage source (5). The calculation means (2a) also performs control such that a sampling timing is fixed at the end point of the pulse width (tp) of voltage vectors regardless of the DC voltage detection value (Vdc).
