    摘要： A hybrid electric vehicle (HEV) has an algorithm for executing a method for diagnosing a high-voltage (HV) fault condition aboard the HEV. The HEV includes a high-voltage (HV) battery, an auxiliary power module (APM), a power inverter module (PIM), and a three-phase motor/generator unit (MGU). A controller executes the method to thereby measure a DC output current from the HV battery, a DC inlet current into the APM, and a pair of AC phase currents in the MGU. The method further includes calculating a DC inlet current into the PIM using the AC phase currents, diagnosing the HV fault condition using the DC output currents and the DC inlet currents, and executing a control action in response to the diagnosed condition. The method can include shutting off the APM to determine whether the APM is the root cause of the HV fault condition.

    摘要： Methods and apparatus are provided for determining whether one or more inverter sub-modules of an inverter module is operating properly. Amplitude of each stator current signal is regularly measured. For each current signal, a positive counter counts a number of consecutive times the amplitude of that current signal is less than a positive current threshold, while a negative counter counts a number of consecutive times the amplitude of that current signal is greater than a negative current threshold. If the positive counter or the negative counter exceeds a maximum count, it is determined that an inverter sub-module is operating abnormally.

    摘要： In accordance with exemplary embodiments, rotor temperature estimation is provided for estimating rotor temperatures of an electric motor in an electric vehicle. A method comprises estimating a rotor temperature in a controller for an electric motor of a vehicle using a fast-mode rotor temperature estimator for a time interval, and then deactivating the fast-mode rotor temperate estimator after the time interval and activating a normal-mode rotor temperature estimator in the controller for the electric motor of the vehicle. A system comprises an electric motor, a resistance rotor temperature estimator including a limit value limiting a temperature estimate increase for temperature estimates, and a controller for the electric motor, which uses the temperature estimate and is configured to temporarily increase the limit value of the resistance rotor temperature estimator providing a fast-mode rotor temperature estimate.

    摘要： A method is provided for controlling an induction motor having a rotor. The method includes receiving a torque command; comparing the torque command to a threshold torque value; generating, with a first estimation module, a first estimated rotor resistance when the torque command is less than or equal to the threshold torque value; generating, with a second estimation module, a second estimated rotor resistance when the torque command is greater than the threshold torque value; and generating control signals for the induction motor based on the first estimated rotor resistance or the second estimated rotor resistance.

    摘要： Position and speed correction are applied to observed values from a position sensor in order to operate an electric motor. Observed position values and observed speed values are obtained from the position sensor for time points during a sampling window, ideal position values and ideal speed values are determined for each of the time points, and position and speed error values are determined based on the observed and ideal values. Stored position information is updated using the position error values and the speed error values. The electric motor is operated using corrected position values and corrected speed values that are determined from the observed position values, the observed speed values, and the stored position information.
