    摘要: A vector control device includes a vector control unit computing an output voltage output from the electric power converter according to vector control based on torque command and flux command and generating a PWM signal for controlling the electric power converter based on the output voltage, a first flux-command generation unit generating a flux command for asynchronous PWM mode, and a second flux-command generation unit generating a flux command for synchronous PWM mode. When an output frequency of the electric power converter is lower than a predetermined value, a flux command generated by the first flux-command generation unit is input to the vector control unit, and when the output frequency of the electric power converter is equal to or higher than a predetermined value, a flux command generated by the second flux-command generation unit is input to the vector control unit.

    摘要: 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.
