METHOD AND SYSTEM FOR ADJUSTING HYBRID VEHICLE DRIVELINE TORQUE

摘要

Methods and systems for improving operation of a hybrid vehicle are presented. In one example, an engine torque estimate may be adapted in response to a torque converter impeller speed error. The methods and systems may reduce the possibility of driveline torque disturbances.

1. A method for controlling hybrid engine torque output, comprising:
during a transient torque increase responsive to a change in desired powertrain output torque, adjusting engine output torque and motor output torque responsive to the change in desired powertrain output torque, and further adjusting motor output torque in response to a torque converter impeller speed response.
