Abstract
A method and system of providing hydraulic pressure during a transition from gas-powered engine operation to electric motor operation in a hybrid electric vehicle. During the transition, main pressure arising from operation of a gas-powered engine with a main pump is matched with auxiliary pressure arising from operation of a battery-powered electric motor with an auxiliary pump. After matching the main and auxiliary pressures, the auxiliary pressure is boosted to an operational pressure in response to a triggering event.
