  • Methods and systems for a hybrid vehicle
    Patent number: 9108638
    Abstract: Systems and methods for learning torque estimate errors and updating torque estimation models are presented. In one example, torque errors are learned during an engine shut-down, after a disconnect clutch coupled between an engine and an electric machine has been released. An updated torque estimation model is then used to control torque during subsequent engine operation to improve drive feel and vehicle performance.

  • SYSTEMS AND METHODS FOR DRIVELINE TORQUE CONTROL
    Publication number: 20150198243
    Abstract: Systems and methods for improving operation of a hybrid vehicle are presented. In one example, a difference between estimated torque output of an active torque source in a driveline and actual torque output of the active torque source is mitigated via entering a driveline speed control mode. The methods and systems may be useful when switching between different driveline modes of operation.
