Abstract
Official abstract text for this publication.
A method of controlling a power inverter coupled to an electric motor in a vehicle powertrain having an engine is provided. The method includes generating a voltage waveform signal and a switching frequency signal for the inverter via a controller. At least one of the voltage waveform signal and the switching frequency signal is at least partially based on at least one commanded engine operating parameter. For example, the engine on/off state, engine torque, and engine speed can be considered. A vehicle having a controller configured to implement the method is also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling a power inverter coupled to a controller, to a voltage source, and to an electric motor in a vehicle powertrain having an engine, wherein the power inverter has inverter switches movable between open and closed positions, the method comprising: receiving via the controller a commanded engine operating parameter; wherein the commanded engine operating parameter includes at least one of a commanded on/off state of the engine, a co…
