    摘要: A first inverter and a second inverter supply two coil sets forming a three-phase motor with AC voltages, which are the same in amplitude but shifted by 30° in phase. Current detectors detect phase currents supplied from the inverters to the coil sets. Temperature estimation sections estimate temperatures of the inverters or the coil sets based on an integration value of the phase current detection values. A current command value limitation section limits upper limits of current command values of both coil sets based on the estimated temperatures Tm1 and Tm2. Thus, the inverters and the coils sets are protected from overheating without increasing torque ripple.

    摘要: An electrically driven power steering control apparatus for a vehicle gives a steering assist torque to a steering mechanism by supplying electric power to an electrically driven motor based on a steering operation made by a driver. This control apparatus detects tiredness of a driver, and restricts an operation of the electrically driven motor based on the detected tiredness of a driver.

    摘要: A sensitivity switchable detection circuit includes a high gain circuit for outputting a first signal, a low gain circuit for outputting a second signal, and an output switching circuit for switching between the first signal and the second signal. When the first signal is smaller than a lower limit, the first signal determines a detected signal. When the second signal is larger than an upper limit, the second signal determines the detected signal. When the first signal is larger than the lower limit and the second signal is lower than the upper limit, a weighting function that uses the first signal and the second signal as input variables determines the detected signal.

    摘要: In an electric motor drive apparatus capable of reliably preventing adverse effects on an electric motor, when a control force detected by a torque sensor exceeds a predetermined value, a temperature storing unit stores a temperature detected by a thermistor at that time, and a deviation calculating unit calculates a deviation between the next temperature detected by the thermistor and the temperature stored in the temperature storing unit. When the calculated deviation exceeds a predetermined value, a current limit decision unit sends a limit signal to a current limiting unit. Upon receipt of the limit signal, the current limiting unit gradually decreases the upper limit value of current flowing in the electric motor at a predetermined time interval.
