1. A vehicle system comprising:
a powertrain including an electric motor operatively coupled with an automated manual transmission; and
an electronic control system including a gear shift control module, a transmission control module, and a motor control module in operative communication with one another over one or more controller area networks;
wherein the electronic control system includes supervisory controls configured to:
arbitrate between a plurality of motor operation requests received over the one or more controller area networks to select a winning motor operation request, each of the plurality of motor operation requests including a parameter indicating a requested operation of the motor and a priority parameter, the supervisory controls arbitrating between the plurality of motor operation requests by evaluating the priority parameter, the plurality of motor operation requests including an operator torque request,
evaluate one or more shift inhibit conditions, and
command the electric motor to provide the winning motor operation request when none of the one or more shift inhibit conditions evaluate as true.
