    摘要: A device for controlling an alternating-current motor includes a resolver for detecting a rotational position of an alternating-current motor; and a rectangular wave voltage control unit for performing control based on an output of the resolver to provide a rectangular wave voltage to each phase of the alternating-current motor. The control unit causes an amount of change Δθ in a voltage phase of the rectangular wave voltage of each phase from a switching reference phase of each phase to increase or decrease equally for each switching in one cycle of an electrical angle determined based on the output of the resolver. In this way, a device for controlling an alternating-current motor is provided to restrain occurrence of an offset current upon rectangular wave voltage control.

    摘要: A rotary electric device control device is formed substantially by three signal process flows. A first component is a part generating a 3-phase drive signal supplied from a torque instruction value to an inverter circuit. This is the part from d,q current map to a PWM conversion. A second component detects a drive current value from a motor/generator and feeds back it to the current instruction. This corresponds to a loop for performing coordinate conversion of the drive current and inputting it as a current instruction value to a subtractor. A third component calculates a drive power and rpm of the motor/generator, acquires an estimated torque value, compensates the current instruction value according to the estimated value, and compensates a torque change. This corresponds to a power calculation, an rpm calculation, a torque estimation, and a current instruction compensation unit.

    摘要: In the hybrid vehicle, a boost converter is controlled to make a post-boost voltage or a voltage on the side of an inverter become a target post-boost voltage corresponding to a target operation point of a motor in accordance with a target post-boost voltage setting map that divides an operation region of the motor into a non-boost region and a boost region when a operation point of the motor is included in the boost region. The target post-boost voltage setting map is prepared so that the non-boost region includes a region in which a loss produced by driving the motor when not boosting the post-boost voltages becomes smaller than the loss produced when boosting the post-boost voltage and the boost region includes a region in which the loss produced when boosting the post-boost voltage becomes smaller than the loss produced when not boosting the post-boost voltage.

    摘要: A hybrid vehicle generates vehicle driving force by the sum of a direct torque mechanically transmitted directly from an engine to a drive shaft through a power split device and an output torque of an MG. A PM-ECU selectively applies a running mode in which outputs of the engine and the MG are controlled such that the requested driving force for the entire vehicle is exerted on the drive shaft; and an S/D mode in which the requested driving force is exerted on the drive shaft by the direct torque in the state where the output torque of the MG is set at zero. An MG-ECU stops the operation of a power converter for controlling the output of the MG when the S/D mode is applied.
