  • Patent number: 9124208
    Abstract: In a vehicle, a control apparatus controls a power converter supplying a rotary machine which can operate as a drive motor of the vehicle, and controls a cooling apparatus for circulating a coolant fluid through the rotary machine and the power converter. When a temporary condition occurs immediately after commencement of the circulation, whereby the temperatures of the coolant fluid and of switching elements in the power converter are judged to concurrently exceed respective specified temperature thresholds, the control apparatus limits the maximum power that can be supplied from the power converter to a lower value than is normally available. When the temperature of the coolant fluid is judged to no longer exceed the corresponding temperature threshold, the limiting is released.

  • Patent number: 8884567
    Abstract: In a system for controlling a rotary machine, a circuit outputs an AC voltage to be applied to a rotary machine. A storage stores therein measurement-error information indicative of a measurement error of the measuring unit. A torque-feedback adjuster manipulates a phase of the output voltage of the circuit based on the rotational angle of the rotary machine measured by a measuring unit and the measurement-error information to adjust a torque of the rotary machine to a request torque. The phase is obtained from information fed back from the rotary machine. An abnormality determiner determines whether there is an abnormality to disable using accurate measurement-error information. A limiter limits adjustment of the torque of the rotary machine to the request torque by the torque-feedback adjuster when it is determined that there is an abnormality to disable using accurate measurement-error information.
