An engine control system comprises a first torque request module that generates a first torque request, a second torque request module that generates a second torque request, a torque arbitration module, an arbitration feedback module, and a torque control module. The torque arbitration module selects one of the first and second torque requests and outputs an arbitrated torque based on the selected one of the first and second torque requests. The arbitration feedback module reports a status signal to the first torque request module. The status signal has a first value when the first torque request is the selected one of the first and second torque requests. The torque control module controls an engine to produce the arbitrated torque. The power source includes an internal combustion engine.
