Abstract:
1. Method for controlling a powertrain system including an engine and a torque actuator coupled to an output member, the output member coupled to a driveline to transfer tractive power to a wheel including a friction brake, the torque actuator operative to react tractive power transferred from the wheel, the method comprising: monitoring an operator braking request and determining a request for regenerative braking torque; monitoring the request for regenerative braking torque; commanding the torque actuator to react tractive power based upon the monitored request for regenerative braking torque; monitoring achieved regenerative braking torque; and inhibiting operation of the torque actuator when a fault is detected in one of the monitored request for regenerative braking torque and the monitored achieved regenerative braking torque.
