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.

摘要： A hybrid powertrain system includes torque generative devices to transfer power to an output member. An operator torque request, a rotational direction and speed of the output member, and a signal output from a transmission range selector are monitored. When a change in a direction of intended motion is determined, the powertrain system can change rotational direction of the output member when the speed of the output member is less than a threshold. The powertrain can inhibit a change in the rotational direction of the output member.

摘要： A method for controlling the cranking of an engine of a vehicle powertrain system having a rechargeable energy storage system that is adapted to provide electric power to an electric machine, wherein the system is adapted to exit from the engine crank state as a function of an output voltage of the energy storage system to the electric machine during the crank state, if the output voltage is less than a crank undervoltage threshold for a predetermined crank time. According to the method, the crank undervoltage threshold is a function of the number of failed start attempts, generally decreasing as a function of the number of failed start attempts. The predetermined crank time is a function of a magnitude of a difference between the output voltage and the crank undervoltage threshold.
