Engine speed control for an engine in a hybrid electric vehicle powertrain for improved noise, vibration and harshness |
摘要 |
A control strategy is disclosed for regulating speed of an engine in a hybrid electric vehicle powertrain that includes an electric motor and gearing. An electrical power flow path and a mechanical power flow path are established. Electrical power is coordinated with mechanical power to effect an arbitrated engine speed for a given power demand that will result in an acceptable noise, vibration and harshness (NVH) characteristic for the powertrain and an acceptable powertrain efficiency.
