Methods and systems for improving hybrid vehicle performance consistency

摘要

Systems and methods for improving hybrid vehicle performance and efficiency attributes are presented. In one example, an electric machine maximum available torque is controller limited so as to improve conservation of battery charge and driveline performance consistency. The electric machine torque may be limited as a function of driveline speed, battery discharge limit, and other parameters.

1. A driveline method, comprising:
adjusting a maximum driveline torque threshold in response to driveline speed and a battery discharge power limit; limiting driveline torque in response to the maximum driveline torque threshold; and reducing the maximum driveline torque threshold in response to boost pressure.
