Abstract
A start-up method for a hybrid powertrain in which hydraulic pressure is generated in a casual start-up by an electric oil pump motor where certain predetermined conditions are satisfied and the casual start-up is abandoned and hydraulic pressure is generated by an engine where the predetermined conditions are not satisfied. The casual start-up is also abandoned where a vehicle operator seeks propulsion shortly after start-up and before an oil pump is rotating within a predetermined threshold of an oil pump target RPM.
