Method and system for inhibiting operation in a commanded operating range state for a transmission of a powertrain system
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.

| Summary: | 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. |
