Abstract:
A hybrid powertrain system includes an engine and a torque actuator coupled to a driveline to transfer tractive power to a wheel including a friction brake. A method includes monitoring an operator braking request and determining a request for regenerative braking torque. Operation of the torque actuator to react tractive power is inhibited when a fault is detected in the monitored request for regenerative braking torque and achieved regenerative braking torque.
