摘要： An apparatus includes a multi-phase inverter, a fault detector to indicate a detection of a fault, a sensor to provide a speed signal indicative of whether a speed of a PM motor is greater than a transition speed, and a controller. The controller is operable to apply either an open-circuit response or a short-circuit response to the multi-phase inverter. The open-circuit response is applied when the speed of the PM motor is greater less than the transition speed and a fault is detected. The short-circuit response is applied when the speed of the PM motor is less greater than the transition speed and the fault is detected. The transition speed is either a fixed predetermined speed or an adjusted predetermined speed.

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： A control method is provided including detecting transmission output speed and a forward and reverse shift request, and executing inhibit limits when the detected speed exceeds a predetermined threshold speed. The inhibit limits slow the output speed to zero upon detection of a shift request at output speeds above the threshold, with a pedal progression map executed upon reaching zero output speed. The limits approach zero output torque as vehicle speed increases, reaching zero at a relatively high speed and simulating a neutral transmission upon a detected shift request at high speed. A vehicle is also provided having a transmission, a sensor for detecting transmission output speed, a sensor for detecting a shift request, and a PCM having an algorithm and a threshold transmission output speed. The algorithm inhibits a shift event in the direction opposite that of vehicle travel upon detection when vehicle speed is greater than the threshold.
