    摘要: A method for operating a powertrain system including a torque machine coupled to a drive wheel of a vehicle includes determining a regenerative braking capacity of the powertrain system. In response to a net operator torque request including a braking torque request, a friction braking torque command to operate a friction brake system and a regenerative braking torque request for the torque machine are coincidentally generated, a torque command is generated for controlling operation of the torque machine in response to the regenerative braking torque request, and the friction braking torque command is adjusted by an amount corresponding to a difference between the braking torque request and the regenerative braking torque request.

    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.
