Abstract: Systems and methods for improving hybrid vehicle torque control are presented. The system and methods included may estimate driveline torque via springs of a dual mass flywheel. The estimated driveline torque may provide feedback for adjusting operation of a driveline disconnect clutch and/or engine torque.

Abstract: Systems and methods for improving operation of a hybrid vehicle are presented. In one example, a method for transitioning between driveline braking and wheel brakes is provided.

Abstract: Systems and methods for improving operation of a hybrid vehicle are presented. In one example, driveline operation may be adjusted in response to operating the hybrid vehicle in a four wheel drivel low gear range. The approaches may improve vehicle drivability and reduce driveline degradation.

Abstract: A method and a system for improving operation of a hybrid vehicle are presented. In one example, operation of a hybrid driveline is adjusted in response to driving conditions that may cause wheel slip or a stuck vehicle. The approach may reduce driveline wear and improve vehicle drivability.

Abstract: Systems and methods for improving operation of a power take off are presented. In one example, the power take off may be rotated in two different directions. The approaches may improve operation of a power take off device.

Abstract: Systems and methods for reducing driveline mode change busyness for a hybrid vehicle are presented. The systems and methods may delay a driveline mode change in response to a time since a change from a first desired vehicle speed to a second vehicle speed, or alternatively, driveline mode changes may be initiated in response to an estimated time to change from the first desired vehicle speed to the second desired vehicle speed.

Abstract: Systems and methods for improving operation of a hybrid vehicle are presented. In one example, application of a driveline disconnect clutch to start an engine is described. The approach applies the driveline disconnect clutch to rotate an engine and at least partially disengages the driveline disconnect clutch to reduce the possibility of a reduction in torque applied to vehicle wheels.

Abstract: Systems and methods for improving operation of a hybrid vehicle are presented. In one example, operation of a driveline disconnect clutch is adjusted to compensate for clutch wear and manufacturing tolerances.

Abstract: A coaching system for drivers of vehicles monitors the power dissipation of a manual transmission clutch and, when the energy dissipated during an event is excessive, suggests modified driving technique. The system may monitor launch events, shift events, and steady state driving. The system may adjust the energy threshold at which a suggestion is provided based on vehicle weight or road gradient. The system may also adjust the energy threshold when an estimate of clutch temperature is elevated. The suggestion may be provided on a graphic display or may be provided verbally over a speaker. In some cases, the suggested may also be conveyed to a third party outside the vehicle.

Abstract: Systems and methods for improving operation of a hybrid vehicle are presented. In one example, an electrical load may be automatically activated to consume electrical energy produced during driveline braking so that driveline braking may be extended. The electrical load may be a windscreen heater or other device.

Abstract: A method and a system for improving operation of a hybrid vehicle are presented. In one example, torque converter impeller torque from beginning to end of transmission shifting is adjusted in response to variable driveline inertia. The approach may improve transmission shifting and reduce driveline torque disturbances.
