    摘要： A rotor position estimating device includes a voltage application unit, a current detecting unit and an estimating unit. The voltage application unit is configured to apply a d-axis voltage to an electric motor including a salient-pole rotor during a stop of the electric motor. The current detecting unit is configured to detect a q-axis current flowing through the electric motor at the time when the d-axis voltage is applied. The estimating unit is configured to estimate a rotor position during a stop of the electric motor on the basis of the q-axis current detected by the current detecting unit. The voltage application unit is configured to set a voltage application time in correspondence with peak timing at which the q-axis current reaches a peak in a transitional response characteristic of the q-axis current at the time when the d-axis voltage is applied.

    摘要： A vehicle, including a motor having a rotor, a resolver that detects a rotation angle of the rotor and a control device, and a control method for the vehicle are provided. The control device executes rectangular-wave control over the motor using the rotation angle of the rotor, detected by the resolver, executes zero learning for learning a deviation between an origin of an actual rotation angle of the rotor and an origin of the detected rotation angle of the rotor, corrects the detected rotation angle of the rotor on the basis of a result of the zero learning, and, when the zero learning has not been completed yet, executes avoidance control for avoiding a rapid variation in output of the motor.

    摘要： A boost converter boosts a DC voltage of a DC power supply. An inverter converts the output voltage of the boost converter into an AC voltage. A control device that controls the boost converter reduces an output voltage instruction value of the boost converter when the rotation speed of the AC motor decreases and an absolute value of a variation rate of the rotation speed is not less than a predetermined value. The inverter is controlled in the control mode selected from a plurality of control modes including three modes of a sine wave PWM control mode, an overmodulation PWM control mode and a rectangular wave control mode. The control device of the boost converter reduces the output voltage instruction value of the boost converter only when the control mode of the inverter is the rectangular wave control mode or the overmodulation control mode.

    摘要： A plurality of current sensors are provided to correspond to a plurality of inverter circuits for driving a plurality of motor generators, respectively. Zero point adjustment of each current sensor is executed in a non-energized state recognized based on a stop of operation of the corresponding inverter circuit and when noise influence is determined to be small based on stops of operations of the other inverter circuits in the same casing. As a result, it is possible to avoid a risk of performing the zero point adjustment in a state in which an output of the current sensor is not exactly a value corresponding to zero current due to the noise influence from the other inverter circuits. In this way, it is possible to highly accurately execute the zero point adjustment of the current sensor for measuring motor driving current.

    摘要： A fuel cell has a unit cell whose output is increased. A unit cell of a fuel cell includes a cathode electrode having a gas diffusion layer and an electrode catalyst layer. The electrode catalyst layer is made of carbon black carrying a Pt—Mn-based alloy such as a Pt—Mn alloy on its particle surface. For operating the fuel cell which includes the cathode electrode, it is preferable to make the pressure of an oxygen-containing gas supplied to the cathode electrode higher than the pressure of an hydrogen-containing gas supplied to an anode electrode to make the pressure at the cathode electrode higher than the pressure at the anode electrode.
