  • Patent number: 12162520
    Abstract: An electric vehicle control device includes an idling-sliding control unit that provides control to reduce or prevent idling and sliding that may occur on a wheel of an electric vehicle. The idling-sliding control unit includes an idling-sliding detection unit for detecting idling or sliding that has occurred on the electric vehicle, and a torque command value generation unit that generates a torque command value used for reducing or preventing idling or sliding, based on output of the idling-sliding detection unit. When a prediction signal representing an anticipated occurrence of idling or sliding is inputted, the torque command value generation unit performs narrowing of the torque command value regardless of whether or not the idling-sliding control unit is performing idling-sliding control.

  • Patent number: 10910984
    Abstract: A control unit is configured to generate a first switching signal based on a voltage command value and a first carrier and a second switching signal based on the voltage command value and a second different carrier, and a characteristic calculation unit estimates and calculates at least one of a resistance value of an electric motor and a dead time error, which is the difference between an effective value of a dead time and a set value of the dead time, based on a first operating characteristic of a power conversion unit obtained when switching elements are driven with the first switching signal and a second operating characteristic of the power conversion unit obtained when the switching elements are driven with the second switching signal. The resistance value of the electric motor and the dead time error can be quickly calculated and estimated by a common structure.

    Abstract: A power converter includes a control unit that generates a modulated wave synchronized with an output voltage command and a carrier wave having a frequency higher than a frequency of the modulated wave, the control unit controlling the power converter by comparing the modulated wave and the carrier wave to output a switching signal for driving a switching element. When a modulation factor in converting DC power into AC power is equal to or higher than a mode switching modulation factor and is lower than ?/4, the power converter converts the DC power into the AC power in an over-modulation mode, in which switching of the switching element is stopped for a period longer than one cycle of the carrier wave, in a first period in which an output voltage command is positive and timing of a positive peak value of the output voltage command is included.
