  • Patent number: 9429275
    Abstract: A hydraulic system for a hybrid module which is located between an engine and a transmission includes a parallel arrangement of a mechanical pump and an electric pump. Each pump is constructed and arranged to deliver oil to other portions of the hydraulic system depending on the operational mode. Three operational modes are described including an electric mode, a transition mode, and a cruise mode. Included is a lube splitter valve which prioritizes the delivery of oil between downstream components and the motor (eMachine). The motor temperature is monitored and an elevated motor temperature provides an indication of a clogged oil filter.
