    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 method of regulating a torque output of each of an internal combustion engine (ICE) and an electric machine (EM) in a hybrid powertrain system includes determining a desired axle torque of the hybrid powertrain system and arbitrating the desired axle torque and a first plurality of torque requests in an engine control module (ECM) of the hybrid powertrain system to provide an arbitrated axle torque request. The method further includes arbitrating a torque request, which is based on the arbitrated axle torque request, and a second plurality of torque requests in a hybrid control module (HCM) to provide a final torque request, and generating ICE control signals and EM control signals based on the final torque request.
